Description

Construction waste removal system and method {SYSTEM AND METHOD FOR CONSTRUCTION WASTE REMOVAL}

The present invention relates to the removal of waste, in particular from waste from construction sites, commercial areas, industrial waste sites, townhouses, multi-family homes and condominiums.

In construction sites for new construction sites, remodeling, building refurbishment or modernization, industrial waste sites, one of the problems faced by builders, construction companies or construction establishments is the generation of significant amounts of waste and removal of waste. Conventional methods of removing waste and rubbish at construction and industrial sites have been implemented with multiple containers or bins for collecting waste at various locations on construction and industrial sites. Conventional containers or bins have a length of 6 meters, a diameter of 1.8 to 2.4 meters and a height of 0.9 to 2.4 meters. Such containers are commonly referred to as "roll-off" containers and may be wheeled to produce moving roll-off containers in fixed roll-off containers. Such rolloff containers typically have three standard dimensions: first 20 cubic yards, second 30 cubic yards, and third about 40 cubic yards.

For example, a 20 yard rolloff container is most effectively used at construction sites that handle heavy waste such as broken stone, concrete, asphalt, soil, bricks and tiles. 30 and 40 yard roll-off containers accept and store wood shavings, plasterboard, broken shingles, tree branches and finishing shavings, business and household waste, packaging waste such as cardboard, and lightweight materials such as cardboard and packaging materials. Regardless of the rolloff container selected, these rolloff containers are too heavy to lift in a truck with a front or rear end loader or to empty construction waste. Instead, the combined rolloff truck must pick up the rolloff container.

Such coupled rolloff trucks typically have a power inclined flatbed having a power winch at the front end (cap) of the truck. When a rolloff container is loaded, for example when loaded into a rolloff truck, when the container is delivered to its intended place of use, and filled to dump to a dumping site, the rolloff truck must come to the front end of the container. The front end of the truck bed is inclined upwards until the rear end of the bed is near the ground or pavement surface. The cable from the wave winch is attached to the load of the truck at the front end of the rolloff vessel and the vessel is winched up into the rolloff frame of the truck bed and the vessel rolls on the wheels. When the container is always winched on the roll-off frame of the truck bed, the container is locked in place and the truck bed is returned to its normal horizontal position and tilted. Empty roll-off containers may be placed at the intended place of use by separating from the roll-off truck at the storage facility or by reversing the above loading sequence.

The technique using a rolloff truck is not sufficient and time consuming. Rolloff trucks are run on a single rolloff truck process at a time for each rolloff container at the construction site, requiring a separate trip to the waste handling facility even if the rolloff container is not full. Another problem with the technique is that conventional roll-off vessels are made of heavy material such as metal and are made of a single integrated unit that cannot be disassembled. As such, each rolloff container has a fixed space that requires a certain amount of space at the construction site, regardless of whether the rolloff container is in use or waiting for use. Many construction sites have limited space for waste containers and empty roll-off containers.

Another problem relates to emptying the rolloff container. A central container with a special large dumping facility designed to lift the container upside down and empty it to empty the waste contents is common. Such dumping equipment is often expensive and requires skilled technicians to operate it. Moreover, it is not possible to make the waste in the roll-off container small to contain more waste in a roll-off container of the same size as a 30, 40, 60, 75 or 100 cubic yard container. Thus, despite the actual amount of waste in the roll-off container that will be much smaller than the capacity of the container, the central waste container has a capacity associated with the container having a constant size instead of a smaller amount based on the actual amount of construction waste in the container. Will fill it completely.

An object of the present invention is to overcome the problems of the prior art, and relates to a method, system and apparatus for removing waste at a construction site or industrial site.

One embodiment of the invention provides a system for removing construction waste. The system includes an assembled waste chute, the assembled waste chute having a set of waste chute sections joined together end to end and a waste container for disassembly configured to receive waste from a downstream end of the assembled waste chute. .

Embodiments of the present invention relate to methods, systems, and apparatus for removing construction waste from a construction site. According to an embodiment of the present invention, at the construction site, the end-to-end may be coupled to each other such that the multiple chute sections constitute the waste removal chute of the waste removal system. The constructed or assembled waste removal chute may be installed in a multistory building. In the disassembled state, the dismantled waste container can be transported to the construction site. The dismantled waste container is assembled and positioned to receive waste from the downstream end of the waste removal chute. A waste transport vehicle with a holding device, i.e., a gripper, is a central waste container which is configured to remove waste collected in a dismantled waste container, loads the waste into a waste receiving bed of the waste transport vehicle, and which can be provided in the waste removal system. It is configured to transport the collected wastes.

1 is a diagram of a waste removal chute and waste container of a waste transportation system constructed in accordance with the principles of the present invention. As shown in FIG. 1, the waste transportation system 100 includes a waste removal chute 102, a waste container 104, and a waste transportation vehicle 106 having a gripping device 204, that is, a disposal arm (FIG. 2). Reference). The waste removal chute 102 includes multiple chute sections 110 and end chute sections 112. Each chute section 110 includes a hole located proximate the lateral angle hopper 114. The foundation of the side angle hopper 114 may be attached to the building floor 108 of a multi-story building. The height between building floors is between about 315 cm and about 465 cm. A detailed description of the chute section 110 is described below with reference to FIG. 3.

The waste container 104 is a dismantled waste container that can be assembled and positioned to be received downstream of the waste removal chute 102, ie from the chute section 112. For example, as shown in FIG. 1, the dismantled waste container 104 is located below the output end of the chute section 112. The dismantled waste container 104 may include a plurality of walls, ie a pair of sidewalls, a removable front wall, a removable back wall, and a removable bottom coupled to the plurality of walls. To describe in more detail the structure of the dismantled waste container 104, see patent application 12 / 058,412, entitled "Waste Removal Vessel Structure," filed March 28, 2008, which is incorporated herein by reference. Just do it.

2 shows a perspective view of a waste holding truck of a waste transportation system constructed in accordance with the principles of the present invention. As shown in FIG. 2, the waste holding truck 106 of the waste transportation system 100 is supported by the front and rear wheels 205, 207, respectively, and is arranged along the longitudinal axis of the truck 106. It includes a chassis (201) including). The main frame 203 further includes an operator cap 202, a boom 204 and a waste receiving truck bed 206. The worker cap 202 may be mounted to the chassis 201 in front of the truck 106. The chassis 201 may be mounted adjacent to the boom 204 and worker cap 202, which in turn mount the gripping material gripping mechanism 216. As shown in FIG. 5, in an embodiment, the gripping mechanism 216, i. And a first jaw 228 and a second jaw 230. Base 232 may be coupled to boom 204 by pivot pin 229. The opening and closing of the first jaw 228 and the second jaw 230 are controlled from the operator control console 222 at the operator station 220 and can be activated by another pair of hydraulic members 238, 240. The boom 204 is a relatively pivotable and extendable member 224, 226 interconnected by a hydraulic cylinder 225 and a pivot 227 that are selectively operable to move relative power between the boom members 224, 226. ). The other hydraulic cylinder 223 may be interposed between the brace 221 and the boom element 224 so that the position of the boom element 224 can be changed. In this manner, the gripper device 216 may be moved from the dismantled waste storage position to the working position when the gripper is located in the receiving area of the dismantled waste container 104.

As the gripping mechanism 216 is customized, the jaws 228 and 230 have a cutting edge 250 having a length of about 122 cm made of reinforced steel. In an embodiment, the width of the gripping mechanism 216 may be increased by a 1.27 cm thick sheet steel by welding to the gripping mechanism 216. Note that the increased width of the gripping mechanism provides a large waste bonding surface area on the outer sides of the jaws 228, 230, which means that when the gripper 216 collides, the crushing and compressing capabilities of the gripping mechanism 216 Improves. The debris and debris are compressed and compacted to be pressed into the waste receiving truck bed 206. Accordingly, the speed at which the waste receiving truck bed 206 is loaded and compressed is greatly improved by increasing the working surface area 252 of the jaws 228 and 230. When fully deployed, the jaws 228 and 230 of the gripping mechanism 216 open about 19 cm.

The waste receiving truck bed 206 is formed by the front wall 210, the rear wall 211 and a pair of side walls 214. The pair of side walls 214 are spaced apart from each other by respective widths of the front wall 210 and the rear wall 211, respectively. Each sidewall 214 includes an extension flap 212 that preferably exceeds the height of each sidewall 214 above each height of the front wall 210 and the rear wall 211. Each extension flap 212 is rotatably connected to each sidewall 214 and retains waste in the waste receiving truck bed 206 to increase the total amount of construction waste located within the waste receiving truck bed 206. And the waste is reduced by the use of a smaller gripping mechanism 216 to fill the waste receiving truck bed 206 against the waste capacity. Thus, the use of the extension flap 212 and / or the use of the gripper 216 is greatly improved over conventional rolloff containers and their associated rolloff trucks, and the transport vehicle 106 is partially filled (not compacted) in the waste reservoir. Instead of a partial load pouring out of the rolloff vessel, it may have a total load corresponding to the compacted capacity of one or more vessels.

3 shows a perspective view of a single section of the waste removal chute shown in FIG. 1 constructed in accordance with the principles of the present invention. As shown in FIG. 3, the chute section 110 is a 90 cm diameter rolled steel tube, ie a side wall 306, made of 16 gauge galvanized steel forming an upstream end 301 and a downstream end 304. It may be a steel tube. The chute section 110 has a cross section 312 and has a hole at the downstream end 304 that is the same upstream end 302 as the hole or cross section 314. In an embodiment, the chute section 110 has ribs or rims 308, 310 at the ends 302, 304, respectively. The lip or rim 308 of the first chute section 110 is configured to engage with the lip or rim 310 of the second chute section 110. At this joining point, the first chute section and the second chute section are joined end to end to form one continuous waste chute.

In an embodiment, the cross-section or hole of the upstream end 302 is such that the cross-section of the downstream end 304 can be pressurized to the upstream end 302 such that the cross-section of the downstream end 304 forms a strong union between the two chute sections 110. Have a slightly larger cross-section or hole than 304). The formed strong union may be further reinforced by welding. In an embodiment, the chute section 110 is made of a gauge of metal thickness and / or other metal, such as a 16 gauge galvanized sheet metal, to form a rolled tube along various diameters. In addition, the individual chute sections 110 may be between 315 and 465 cm because the height between the floors of the building varies between about 315 and about 465 cm. Alternatively, one or more chute sections may be joined together to correspond to the floor height of a particular building.

FIG. 4 shows a perspective view of the side angle hopper of the waste disposal chute section shown in FIG. 3. As shown in FIG. 4, the lateral angle hopper 114 may be secured to the waste removal chute section 110 to include a hole 403 for receiving waste into the assembled waste chute 102. The side angle hopper 402 has a lower panel 406 forming a hole 403 and a pair of side panels 404 coupled to the back panel 402. In an embodiment, the bottom panel 406 of the side angle hopper 114 receives bolts such that the side angle hopper 114 can be bolted to the building floor 108 to provide support to the assembled removal chute 102. A plurality of holes 408 for the purpose. Although FIG. 4 shows the bottom panel 406 of the lateral angle hopper 114 with four holes 408, more or fewer holes are used for the lateral angle hopper 114 (waste) with respect to the building floor 108. It may be provided to properly secure the removal chute 102. In an embodiment, the side angle hopper 114 may be formed of different metals, to form side angle hoppers according to the metal thickness of different diameters and / or gauges. That is, it can be formed from galvanized sheet metal of 10 gauge or the like.

In operation, the waste removal system can be greatly reduced in overall cost, providing a more efficient process for removing waste at construction sites. The process of removing construction waste from the construction site involves transporting a series of waste chute sections at the construction site, joining a series of waste chute sections together end-to-end to assemble the waste chute, and installing the waste chute in a multi-story building. It includes. The process transports one or more dismantled waste containers to the construction site, connects several side members to the foundation member corresponding to adjacent side members, assembles 20 to 120 yards of dismantled waste containers, and downstream of the installed waste chute. It may further comprise installing one or more dismantled waste containers to receive waste from the stage and downstream of the installed waste chute. The process may further comprise preparing a waste transport vehicle, removing waste received from the dismantled waste container, and placing it on a waste receiving bed of the waste transport vehicle. Waste received from dismantled waste containers may be compressed and compacted in a waste receiving bed of a waste transport vehicle by a gripping mechanism 216 such as a gripper or a pair of extension flaps 212. For example, the waste receiving bed of a waste transport vehicle has a compact capacity of 40 cubic yards. The waste transport vehicle removes waste from the first waste container having a non-compact capacity of 20 cubic yards. Next, the waste transport vehicle removes the waste from the second waste container having a non-compact capacity of 20 cubic yards. The waste transport vehicle is relocated and removes waste from a third waste container having a non-compact capacity of 20 cubic yards. Next, the waste transport vehicle removes waste from the fourth waste container having a non-compact capacity of 20 cubic yards. In this embodiment, if a rolloff truck associated with a conventional rolloff container is used, four trips are required for the central waste container corresponding to 8 cubic yards of waste filling. Instead, the disclosed waste removal system and method of the present invention consists of a single trip of the central waste container corresponding to the filling of 40 cubic yards of compact waste. Thus, the disclosed waste removal systems and methods can save a significant amount of manpower, fuel, tire wear, time and cost compared to prior art rolloff systems. Finally, the fully packed waste transport vehicle can be moved to a central waste container to load the collected construction waste.

While the invention has been described in terms of preferred embodiments, the invention is not limited to the specific constructions disclosed and by way of example shown in the drawings. It is to be understood that modifications and equivalents are possible without departing from the scope of the present invention.
