Description

Technical Field

[0001] This utility model relates to the field of waste disposal site drainage technology, specifically a waste disposal site flow guiding and erosion prevention structure. Background Technology

[0002] Spoil disposal sites are a general term for sites chosen for the disposal or stockpiling of unusable excavated earth and rock, demolished concrete, or their mixtures during engineering construction. These sites are most prone to severe soil erosion and even disasters. Soil erosion at spoil disposal sites includes hydraulic erosion, gravity erosion, mixed erosion, and wind erosion, with hydraulic erosion having the greatest impact. In situations with large upstream catchment areas and concentrated rainfall, improper drainage can cause erosion of the spoil, easily leading to collapses and debris flows, threatening the safety of sensitive downstream points. Therefore, reasonable and effective flood control and drainage engineering at spoil disposal sites is extremely important for their safety and stability.

[0003] Existing drainage measures for spoil heaps mainly involve setting up seepage blind ditches at the spoil heap base. However, some spoil heaps have large spoil heights and loose backfill, making it easy for surface water to seep in and soften the spoil. Setting up drainage channels only at the base cannot quickly and effectively remove water from inside the spoil heap. Rainwater rushes down the slope from the top, causing the slope to be eroded, resulting in surface erosion and gully erosion, and even threatening the slope stability of the spoil heap. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a highway crack repair device, which solves the problem that existing waste disposal site drainage measures cannot quickly and effectively remove water from inside the waste disposal site, and also solves the problem that the slope is eroded by rainwater, threatening the stability of the waste disposal site slope.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste disposal site diversion and erosion prevention structure, including a drainage ditch set on a slope, a cover plate installed above the drainage ditch, filter holes evenly distributed on the cover plate, and a wire mesh covering the slope surface between two drainage ditches, the wire mesh being fixed to the slope by an anchoring component.

[0006] With the above structural design, rainwater from the slope flows into the drainage ditch during rainy weather. The cover plate with filter holes installed at the top of the drainage ditch filters the rainwater, effectively blocking large particles of slag and garbage mixed in with the rainwater. This prevents debris from accumulating in the drainage ditch and affecting the drainage effect. Covering the slope with wire mesh can effectively solve the problem of slag landslides and prevent the slag dump from collapsing.

[0007] Preferably, the anchoring assembly includes a sleeve passing through the wire mesh, a cone head fixedly installed at the lower end of the sleeve, a connecting rod installed inside the sleeve, a fixed rod symmetrically rotatably connected to the connecting rod, a fixing groove opened on the sleeve near the fixed rod, a threaded rod installed at the upper end of the connecting rod, a rotating cylinder sleeved on the threaded rod, the rotating cylinder being threadedly connected to the threaded rod, and a turntable fixedly connected to the upper end of the rotating cylinder passing through the sleeve.

[0008] By adopting the above structural design, the rotating disc causes the rotating drum and the threaded rod to rotate relative to each other, thereby causing the threaded rod and the connecting rod to move downward. During the downward movement of the connecting rod, the fixing rod gradually extends out of the fixing groove, thereby increasing the anchoring strength of the anchoring component to the wire mesh and reducing soil erosion caused by rainwater scouring on the slope.

[0009] Preferably, the bottom of the drainage ditch is provided with baffles at equal intervals along its length.

[0010] By adopting the above structural design, the water baffle can effectively slow down the flow rate of water in the drainage ditch, prevent the water from damaging the main body of the drainage ditch due to excessive water flow, and extend the service life of the structure. At the same time, the water baffle can block the debris in the water flow and prevent the debris from accumulating at the bottom of the drainage ditch.

[0011] Preferably, water inlet pipes are provided on both sides of the drainage ditch, with one end of the water inlet pipe extending into the drainage ditch and the other end inserted into the slope.

[0012] By adopting the above structural design, rainwater that seeps into the slope is introduced into the drainage ditch through water pipes, thereby reducing the softening effect of rainwater on the slag soil.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. During rainy weather, rainwater from the slope flows into the drainage ditch. The cover plate with filter holes installed at the top of the drainage ditch filters the rainwater, effectively blocking large particles of slag and garbage mixed in with the rainwater. This prevents debris from accumulating in the drainage ditch and affecting the drainage effect. Covering the slope with wire mesh can effectively solve the problem of landslides caused by waste disposal and prevent the waste disposal site from collapsing.

[0015] 2. By rotating the turntable, the drum and the threaded rod rotate relative to each other, which in turn causes the threaded rod and the connecting rod to move downward. As the connecting rod moves downward, the fixing rod gradually extends out of the fixing groove, thereby increasing the anchoring strength of the anchoring component to the wire mesh and reducing soil erosion caused by rainwater scouring on the slope.

[0016] 3. By setting up a water baffle, the flow rate of water in the drainage ditch can be effectively slowed down, preventing the water from flowing too fast and damaging the main body of the drainage ditch, thus extending the service life of the structure. At the same time, the water baffle can block the debris in the water flow and prevent the debris from accumulating at the bottom of the drainage ditch.

[0017] 4. Rainwater that seeps into the slope is introduced into the drainage ditch through water pipes to reduce the softening effect of rainwater on the slag. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a diversion and anti-erosion structure for a spoil disposal site, including a drainage ditch 1 set on a slope 5. Multiple drainage ditches 1 are set at equal intervals along the slope of the spoil disposal site. A cover plate 2 is installed above the drainage ditch 1. The two ends of the cover plate 2 are snapped into the side wall of the drainage ditch 1. The cover plate 2 is evenly distributed with filter holes 201. A wire mesh 3 is covered on the slope between two drainage ditches 1. The wire mesh 3 is fixed to the slope 5 by an anchoring component 4.

[0024] The anchoring assembly 4 includes a sleeve 401 passing through the wire mesh 3. A cone head 402 is fixedly installed at the lower end of the sleeve 401. A connecting rod 403 is installed inside the sleeve 401. A fixing rod 407 is symmetrically rotatably connected to the connecting rod 403. A fixing groove 408 is opened on the sleeve 401 near the fixing rod 407. A threaded rod 404 is installed at the upper end of the connecting rod 403. A rotating cylinder 405 is sleeved on the threaded rod 404. The rotating cylinder 405 is threadedly connected to the threaded rod 404. The upper end of the rotating cylinder 405 passes through the sleeve 401 and is fixedly connected to a turntable 406. One end of the fixing rod 407 connected to the connecting rod 403 is located above the other end of the fixing rod 407. A limiting cylinder 409 is fixedly connected to the lower end of the sleeve 401, and the lower end of the connecting rod 403 extends into the limiting cylinder 409.

[0025] Water baffles 101 are provided at equal intervals along the length of the bottom of the drainage ditch 1.

[0026] Water pipes 102 are provided on both sides of the drainage ditch 1. One end of the water pipe 102 extends into the drainage ditch 1, and the other end of the water pipe 102 is inserted into the slope 5.

[0027] Working principle: In use, a wire mesh 3 of the same size as the slope surface of the spoil disposal site is covered on the slope 5. Several anchoring components 4 are driven into the slope 5 along the side of the wire mesh 3. Then, the turntable 406 is rotated, so that the rotating drum 405 and the threaded rod 404 rotate relative to each other. This causes the threaded rod 404 and the connecting rod 403 to move downward. During the downward movement of the connecting rod 403, the fixing rod 407 gradually extends out of the fixing groove 408, thereby increasing the anchoring strength of the anchoring components 4 to the wire mesh 3. During rainy weather, rainwater on slope 5 flows into drainage ditch 1. The rainwater flowing into drainage ditch 1 is filtered by the cover plate 2 with filter holes 201 set on the upper part of drainage ditch 1. The water baffle 101 set in drainage ditch 1 can effectively slow down the flow rate of water in drainage ditch 1 and prevent the water from damaging the main body of drainage ditch 1 too fast. The water pipe 102 introduces the rainwater that seeps into slope 5 into drainage ditch 1, reducing the softening effect of rainwater on the slag.
