Abstract
The utility model provides an environmental escape canal of adjustable structure, this structure of includes environmental escape canal and a plurality of adjustable gate, each adjustable gate sets up in environmental escape canal. When the retaining degree of depth in the ditch of environmental escape canal exceedes rectangle flashboard height often, and is at this moment rotatory circular rotatory handle will the spill flashboard slowly promotes extremely need the retaining degree of depth of control in the ditch of environmental escape canal, and will the triangle weir plate is installed on the spill flashboard, make up into a triangle sharp -crested weir, play the double effect of water gaging and accuse water. When run into drain off floodwaters flood season with the ditch in retaining time when reaching two kinds of operating modes of the upper limit, just at this moment require with the rectangle flashboard with the spill flashboard is mentioned simultaneously, and at this moment the adjustable gate is transformed into ordinary control floodgate, and water flows from the pocket floor, reaches the purpose that satisfies the escape canal and drain off floodwaters and impound in function and the evacuation ditch.
Description
Technical field
This utility model patent belongs to irrigation and water conservancy field, relates to having the environmental gutter structure retaining clean-up effect to the polluter entering drainage channel with agricultural area source form.
Background technology
Agricultural non-point pollution is before flowing into small reservoir wetland, and typically through some grades of channel systems, drainage channel covers with various weeds, and peasant often builds some temporary water dash facilities on raceway groove simultaneously, in order to reuse draining, and these all can slow down the speed of draining.Additionally, nitrogen phosphorus is absorbed and adsorbs by plant and soil in raceway groove, denitrogenation, dephosphorization, plant absorption, diafiltration and phosphorus deposition, nitrogen and phosphorus pollutants is converted and absorbs by the microorganism in raceway groove, thus plays nitrogen and phosphorus load in draining and preferably remove and purify.
Conventional drainage system major function meets the most merely the requirement of agricultural year and draining in terms of the water yield.Dirty function is subtracted, it is necessary on the basis of original drainage system, build new-type environmental gutter in order to make drainage system be also equipped with simultaneously.Owing to conventional drainage system is uncontrolled, it is necessary to changing without controlling drainage system is conservative control drainage system.
Summary of the invention
The purpose of this utility model is effectively to remove and purify nitrogen and phosphorus load, control Poyang Lake Basin widespread pollution from the overuse of fertilizers and pesticides in rural area in widespread pollution from the overuse of fertilizers and pesticides in rural area in agricultural drain, it is proposed that a kind of environmental gutter structure meeting draining and subtracting dirty double goal.
Environmental gutter is on the premise of satisfied design water drainage row's stain requires, using wide shallow formula transverse section as far as possible, use shallower longitudinal gradient, both sides are soil-slope, for preventing ditch slope from caving in and beneficially vegetation growth, following three kinds of methods can be used to carry out the design of side slope:
After the degradable ecology bag of a loads the soil being mixed with grass seed, stepped stack in ecological ditch two sides as shore protection, grass seed germinating growth after water flowing, form muskeg in ditch.
Stepped on the bank protection of b trapezoidal cross-section squeezing into several rows of close timber, timber first passes through preservative treatment in advance, then inserts soil between timber, planting plants on the ladder soil filling in soil.
The concrete with honeycombed spots precoated plate with multiple hole, to keep stability of slope, serike in the hole of concrete with honeycombed spots precoated plate are laid in both sides, c gutter.
The wetland plant of described environmental gutter bottom of trench planted on two sides is advisable with local main submerged plant or emergent aquactic plant, the floating plant such as such as Rhizoma Acori Graminei, Medulla Junci, Rhizoma Nelumbinis, Herba Typhae, Canna generalis Bailey, Rhizoma Iridis Tectori (emergent aquactic plant), Flos nymphaeae (Nymphaea teragona Georgi).
For reaching object above, the technical solution adopted in the utility model is a kind of adjustable environmental gutter structure, and this structure includes environmental gutter and multiple adjustable gate, and each adjustable gate locating is in environmental gutter.
Described adjustable gate is made up of rectangle flashboard 1, spill flashboard 2, triangle weir plate 3, chute 4, watertight rubber 5, gate slot 7, threaded hole 8, screw rod 9, connecting rod 10, circular rotating handle 11, rustless steel integral type lock chamber 12, preformed hole 13, guard box 14.
Rectangle flashboard 1 is positioned at the bottom of rustless steel integral type lock chamber 12, and spill flashboard 2 and rectangle flashboard 1 are placed in parallel in the bottom of rustless steel integral type lock chamber 12；Triangle weir plate 3 periphery is provided with chute 4, and triangle weir plate 3 is connected into a triangle sharp-crested weir by chute 4 and spill flashboard 2；Both sides, rustless steel integral type lock chamber 12 top are provided with preformed hole 13 at two; screw rod 9 is rotatably connected in the guard box 14 at rustless steel integral type lock chamber 12 top through threaded hole 8; the female thread matched with screw rod 9 external screw thread it is provided with in threaded hole 8; the top of connecting rod 10 is provided with circular rotating handle 11, and connecting rod 10 rotor shaft direction is consistent with screw rod 9 length direction.
The periphery of rectangle flashboard 1 is provided with gate slot 7, is provided with watertight rubber 5 between rectangle flashboard 1, spill flashboard 2 and rustless steel integral type lock chamber 12.
The top of described rectangle flashboard 1 is provided with overhead kick 6.

Fig. 5 is the front view of triangle weir plate.
In figure: 1, rectangle flashboard, 2, spill flashboard, 3, triangle weir plate, 4, chute, 5, watertight rubber; 6, overhead kick, 7, gate slot, 8, threaded hole, 9, screw rod, 10, connecting rod; 11, circular rotating handle, 12, rustless steel integral type lock chamber, 13, preformed hole, 14 guard boxs.
Detailed description of the invention
As Figure 1-5, adjustable gate is arranged every 300～500m in environmental gutter, it is achieved be adjusted gutter middle water level, day ordinary water level maintain 20～60cm and be advisable.
When the water-storage depth in the ditch of described environmental gutter exceedes described rectangle flashboard 1 the most constantly, at this moment described circular rotating handle 11 is rotated, the water-storage depth controlled is needed in described spill flashboard 2 is slowly promoted to described environmental gutter ditch, and described triangle weir plate 3 is arranged on described spill flashboard 2, it is combined into a triangle sharp-crested weir, the amount of playing water and the double effects of control water.
When run into drain off floodwaters flood season and ditch in storage time reach two kinds of operating modes of the upper limit time, the most just require to mention described rectangle flashboard 1 and described spill flashboard 2 simultaneously, the most adjustable gate is transformed into common control lock, water flows out from pocket floor, the purpose of water-retention in reaching to meet gutter function of flood drainage and empty ditch.
