TECHNICAL FIELD

[0001] The present application relates to the technical field of slope geotechnical treatment, and particularly relates to a protection device for geotechnical slope treatment and a protection method. BACKGROUND

[0002] A slope refers to a slope surface with a certain slope formed on both sides of a roadbed to ensure the stability of the roadbed. In geotechnical engineering, slope protection of the roadbed is extremely important. Water is an important factor leading to slope instability. In the rainy season, excessive rainwater can cause drainage pressure on the slope of the geotechnical engineering, thereby increasing the dead weight of the slope structure and easily causing landslides and other accidents, threatening people's life safety and causing property losses. Generally, we will use a corresponding water seepage prevention structure to protect the slope of the geotechnical engineering to prevent rainwater from seeping into the inside of the slope, thereby achieving the purpose of protecting the slope.

[0003] The existing slope protection device usually uses a geomembrane, a waterproof blanket, a drainage board, a seepage ditch and the like. However, the geomembrane, the waterproof blanket and the like are prone to damage, have low water seepage prevention capability and poor service life. The drainage board and the seepage ditch are not easy to replace in the subsequent maintenance process, require a large amount of manpower and material resources, are complicated to operate, prolong the construction time of the project and need to be optimized and improved. Therefore, the present application provides a protection device for geotechnical slope treatment and a protection method. SUMMARY

[0004] The present application aims to solve the problems in the prior art that the geomembrane, the waterproof blanket and the like are prone to damage, aging or chemical corrosion in construction or use, resulting in a decrease in the water seepage prevention performance, the drainage board and the seepage ditch are buried in the inside of the slope, once blocked or failed, the excavation and repair need to consume a large amount of manpower and material resources, the traditional protection structure is complicated to install, the later maintenance and replacement may need to be completely removed, the construction period is prolonged and the cost is increased, and the present application provides a protection device for geotechnical slope treatment and a protection method.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: A protection device for geotechnical slope treatment, comprising a geotechnical slope body, a protection assembly is fixedly installed on the front face of the geotechnical slope body, a dam is fixedly connected to the outer wall of one side of the geotechnical slope body, and a drainage channel is arranged at the end of the dam away from the geotechnical slope body. The protective assembly includes multiple drainage frames, each of which has a hollow structure inside and drainage grooves on the outer surfaces of the upper and lower ends. A protective plate is fixedly connected to the bottom of the drainage frame, and a mounting rod is fixedly connected to the middle of the lower surface of the drainage frame. A bidirectional screw is rotatably connected to the inside of the mounting rod, and a first movable seat and a second movable seat are threadedly connected to the outer surface of the bidirectional screw. A folding plate is fixedly installed between the first movable seat and the second movable seat, and connecting blocks are fixedly connected to the outer walls of both sides of the first movable seat. The connecting block is fixedly connected to a sleeve rod at one end away from the first movable seat, and a soil-breaking cone is fixedly connected to the bottom of the sleeve rod.

[0006] Furthermore, a plurality of drainage holes are symmetrically and evenly spaced on the outer surface of the drainage frame, and the drainage holes are connected to the drainage grooves. Rainwater inside the drainage frame is guided into the hollow interior of the drainage frame through the plurality of drainage holes and then discharged through the drainage grooves.

[0007] Furthermore, the top of the bidirectional screw passes through the drainage frame, extends to the top and is fixedly connected with a fastening knob. The provision of the fastening knob makes it easier for workers to install and fix the screw.

[0008] Furthermore, a connecting piece is fixedly connected to the top of the drainage frame, and matching connecting holes are provided at positions corresponding to the connecting piece on the top of the drainage frame.

[0009] Furthermore, telescopic columns are symmetrically installed on the bottom of the protective plate, and the outer surface of the telescopic columns is sleeved with a return spring, and the top of the return spring is fixedly connected to the bottom of the protective plate.

[0010] Furthermore, the drainage trough is connected to the dam, and a plurality of drainage pipes are fixedly connected to one end of the dam away from the protective component. Rainwater is discharged into the dam through the drainage trough, and then the rainwater in the dam is discharged through the drainage pipes to avoid infiltration.

[0011] Furthermore, the outer surfaces of the mounting rod and the sleeve rod are provided with through grooves, and the mounting rod and the sleeve rod are slidingly connected. By providing the through grooves, when the bidirectional screw inside the mounting rod rotates, the sleeve rod is driven to slide up and down on the outer wall of the mounting rod through the first movable seat.

[0012] Furthermore, the protective plate fits the slope of the rock and soil slope, and the outer surfaces of the drainage frame and the protective plate are waterproofed. By waterproofing the outer surfaces of the drainage frame and the protective plate, the corrosion of the drainage frame and the protective plate caused by long-term contact with rainwater is slowed down.
