Description

The invention relates to the field of construction, including transport, road and hydraulic engineering, and can be used to strengthen earthworks for various purposes, in particular earthen embankments, dams, slopes of earthworks intended for the construction of various structures on them, etc. objects erected on weak, including swampy soils.

A device for strengthening an earthen structure is known, containing a platform with equipment for manufacturing piles using discharge-pulse technology and installed with the ability to move relative to the crossbars connecting the heads of the support pipes arranged in two rows (RF patent No. 2114957, 1997).

The device allows creating anti-deformation structures in the ground from rows of piles, but is not suitable for installing piles that do not fall into successive rows, if necessary.

It is also known a device for strengthening an earthen structure, including a supporting metal platform mounted on supports, drilling rigs and traction winches to move the platform to a given design step (RF patent No. 2609505, 2016). Another well-known device for the production of construction works contains a platform with the necessary equipment installed with the possibility of longitudinal movement relative to the crossbars connecting the heads of the support pipes arranged in two rows (RF patent No. 2662471, 2017).

And in these cases, the devices are not suitable for installing piles that do not fall into a sequential row, since the drilling rigs, both in the front and in the back of the platform, during operation move along with the platform only in the longitudinal direction and do not move in the transverse direction.

The proposed device, while retaining all the possibilities of installing piles in a row, allows, if necessary, to install additional parallel rows of piles and/or separate piles outside the rows of anti-deformation structures.

The need to install individual piles outside the rows may be caused by avoiding existing obstacles. Also, the transverse movement of the carriage, with drilling equipment placed on it, allows you to significantly expand the area of work on the manufacture and / or installation of piles in one longitudinal pass of the platform (creation of several parallel rows, etc.)

According to the invention, a device for strengthening earthworks contains a platform with working equipment located on its opposite sides for the manufacture and / or installation of piles and a winch. From below, the platform is equipped with longitudinal elements, which are made with the possibility of moving along the roller bearings mounted on the crossbars. Transition devices are movably connected to the crossbars for mounting on the heads of the support pipes. Transverse guides are installed on top of the platform, and equipment for the manufacture and/or installation of piles is placed on carriages that are movable along the transverse guides.

In a preferred embodiment of the invention, equipment for making and/or installing piles includes a drilling rig and a winch. Such equipment is used to make piles directly in the ground by filling drilled holes with a hardening material. However, such equipment can be, for example, piling rigs for driving prefabricated piles into the ground and / or other equipment.

The design of the carriage can be a rectangular frame on rollers mounted on transverse guides. Other forms of carriage are also possible.

The platform may consist of several (at least two) consecutive sections. In this case, the carriages for the drilling rig and the winch are installed on each of the extreme (front and last) sections.

When piles are made directly in the ground by filling drilled holes with hardening material, the equipment placed on the platform may include an electric generator and an electric pulse installation for producing electrical discharges in the holes.

The crossbars on which the platform rests can be made of two connected corner profiles or of an I-profile, with the bottom flange of which the heads of the support pipes are connected.

The essence of the invention is illustrated by drawings.

On FIG. 1 schematically shows the proposed device for strengthening earthworks, side view. On FIG. 2 - carriage in isometric view. On FIG. 3 - crossbar of two corner profiles (top view and bottom view), to which the heads of the support pipes are connected with the possibility of sliding along the crossbar. On FIG. 4 - transition device (glass) for attaching the crossbar to the head of the support pipe, front view.

On FIG. 1, position 1 indicates the platform, position 2 - crossbar, position 3 - roller bearings mounted on crossbars 2, position 4 - carriage, position 5 - transverse guides for carriage 4, position 6 - drilling machine, position 7 - adapter (glass) for attaching the crossbar to the head of the support pipe, position 8 is the support pipe, and the dotted lines below the pipe schematically show the wells.

On FIG. 2, position 9 indicates the clamps for attaching the drilling rig and the winch to the carriage 4. Position 10 indicates the seat for the operator of the drilling rig, position 11 is the handle for the drive of the transverse movement gearbox, position 12 is the device that fixes the position of the carriage after the transverse movement.

On FIG. 3 shows one of the possible designs of the crossbar 2, in which the crossbar itself is made of two corner profiles 13 connected to each other. Rollers 14 are installed on top of the crossbar, allowing you to move the platform in the longitudinal direction. In another constructive version, the bolt is made of an I-profile (not shown in the drawing). The rollers in this case are installed on the upper shelf of the I-beam. Adapter devices (glasses) are movably attached to the lower horizontal shelves of angle profiles or I-beams for mounting on the heads of support pipes, shown in more detail in Fig. four

On FIG. 4, position 15 indicates a reinforcing scarf, position 16 - hooks for the horizontal shelf of the crossbar, position 17 - cover of the adapter (glass)

Platform 1 lower longitudinal elements (not shown in the drawings) mounted on the rollers 14 with the possibility of independent movement relative to the crossbars 2 connecting adapters (glasses) 7 with the heads of the support pipes arranged in two rows. The execution of the platform from several connected sections allows you to move the platform along the slope when it deviates from a straight line.

Equipment for the production of works, in addition to drilling rigs and winches, may include a device for preparing a concrete mixture and water-cement mortar, containing a tank with water, containers with cement, containers with sand, a mortar mixer, a container for washing hoses, a compressor, an electric impulse installation, a device for supplying pipes to platform and installation in wells, etc. However, these components and parts of equipment are not mandatory for the proposed device, and when strengthening earthworks, they can be placed and used without direct connection with the platform.

Platform 1 is moved using a traction winch installed on the platform with a cable passed under the platform through a system of blocks and fixed on a crossbar 2 or an anchor, which is a transverse beam fixed relative to the support pipes.
