Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of slope protection equipment in high-altitude and cold regions, and specifically relates to a slope protection device for high-altitude and cold regions. Background Technology
[0002] Because of the thick snow accumulation in high-altitude and cold regions, a large amount of snowmelt seeps into the soil and cannot be drained. If the snowmelt is not drained for a long time after it seeps into the soil, it can easily cause landslides. Existing water channels that can drain snowmelt from the soil can easily cause soil to flow into the water channels, which is inconvenient for workers to operate and reduces the drainage effect. Summary of the Invention
[0003] The purpose of this invention is to allow workers to channel snowmelt that has seeped into the soil into the irrigation ditch, while preventing soil from flowing into the ditch along with the snowmelt. Furthermore, it prevents the anti-slip net from breaking when used, facilitating worker operation and improving drainage efficiency. The technical solution is as follows:

The slots 2-2 are symmetrically arranged at the upper edges of the left and right sides of the water channel 2-1. A through hole 2-3 is located above the left side of the water channel 2-1. Several support pillars 2-4 are evenly distributed horizontally along the right edge of the through hole 2-3. A waterproof coating 3 is applied to the lower surfaces of both the left and right sides of the water channel 2-1. The left side of the water channel 2-1 has a sloping shape. The filter screen 5 is inserted into the through hole 2-3. The filter device 4 includes a stone slab 4-1, filter holes 4-2, retaining strips 4-3, and pins 4-4. The upper surface of the stone slab 4-1 has a plurality of filter holes 4-2 evenly distributed. Retaining strips 4-3 are symmetrically inserted into the left and right edges of the lower surface of the stone slab 4-1. Each retaining strip 4-3 has a plurality of pins 4-4 vertically arranged evenly distributed in the middle of its lower surface. The retaining strips 4-3 are L-shaped. The retaining strips 4-3 are inserted into the retaining grooves 2-2, and the pins 4-4 are inserted into the lower surface of the retaining grooves 2-2. The stone slab 4-1 is T-shaped.

[0011] Reference Figures 1-4 The slope protection device for high-altitude and cold regions is characterized by comprising a road surface 1 and a drainage device 2 disposed inside the outer edge of the road surface 1. The drainage device 2 has a waterproof coating 3 on its left, right, and lower surfaces. A filter device 4 is inserted in the middle of the upper surface of the drainage device 2. A filter screen 5 is inserted in the middle of the upper left surface of the drainage device 2. A highway slope 6 is connected to the left surface of the road surface 1. A protection device 7 is connected to the middle of the slope surface of the highway slope 6.
[0012] When in use, first lay the protective device 7 on the surface of the roadside slope 6 to prevent the gravel from rolling down the roadside slope 6. When the snow melts, the snow water seeps into the soil. At the same time, the snow water flows down the slope of the roadside slope 6. Then, the snow water is filtered through the filter screen 5 and flows into the drainage device 2. When cleaning the drainage device 2, lift the filter device 4 and open the opening of the drainage device 2. When in use, the waterproof coating 3 prevents the snow water from seeping out of the drainage device 2 and seeping into the road surface 1, causing the road surface 1 to collapse.
[0013] Furthermore, the drainage device 2 includes a water channel 2-1, a slot 2-2, a through hole 2-3, and a support column 2-4. The slot 2-2 is symmetrically provided at the upper edge of the left and right sides inside the water channel 2-1. The through hole 2-3 is provided at the upper part of the left side surface of the water channel 2-1. Several supports 2-4 are evenly distributed horizontally at the right edge inside the through hole 2-3. The waterproof coating 3 is provided on the lower surface of each of the left and right sides inside the water channel 2-1. The left side surface of the water channel 2-1 is sloping. The filter screen 5 is inserted into the through hole 2-3.
[0014] When in use, snow water that seeps into the roadside slope 6 flows into the water channel 2-1 through the through hole 2-3. The support column 2-4 supports the through hole 2-3, and the filter device 4 is inserted into the slot 2-2 so that the upper surface of the filter device 4 is on the same horizontal plane as the upper surface of the water channel 2-1.
[0015] Furthermore, the filtering device 4 includes a stone slab 4-1, filter holes 4-2, clips 4-3, and pins 4-4. The upper surface of the stone slab 4-1 is evenly distributed with a plurality of filter holes 4-2. Clips 4-3 are symmetrically inserted at the left and right edges of the lower surface of the stone slab 4-1. A plurality of pins 4-4 are vertically and evenly distributed in the middle of the lower surface of each clip 4-3. The clips 4-3 are L-shaped. The dotted clips 4-3 are inserted into the slots 2-2. The pins 4-4 are inserted into the lower surface inside the slots 2-2. The stone slab 4-1 is T-shaped.
[0016] In use, first insert the two clips 4-3 into the two slots 2-2 respectively, and insert the nails 4-4 into the lower surface of the slots 2-2 to fix the clips 4-3. Then, insert the stone slab 4-1 onto the clips 4-3. Since the stone slab 4-1, the clips 4-3 and the upper surface of the water channel 2-1 are on the same horizontal plane, the snow water can flow through the filter holes 4-2 into the water channel 2-1 and be discharged.
[0017] Furthermore, the protective device 7 includes a side strip 7-1, a mesh 7-2, anchors 7-3, and barbs 7-4. The mesh 7-2 is inserted into the middle of the inner surface of the upper surface of the side strip 7-1. Several anchors 7-3 are evenly distributed around the middle of the upper surface of the side strip 7-1. Each anchor 7-3 has barbs 7-4 symmetrically connected to the lower side surface of its side. The side strip 7-1 and the mesh 7-2 are laid on the upper surface of the highway slope 6, and the anchors 7-3 are inserted into the inner surface of the upper surface of the highway slope 6.
[0018] When using it, first lay the edge strip 7-1 and the netting 7-2 on the upper surface of the highway slope 6, then insert the anchor nail 7-3 through the edge strip 7-1 into the highway slope 6 to fix the edge strip 7-1. The use of barbs 7-4 can prevent the netting 7-2 from being blown away by the wind, and can seep into the soil through the netting 7-2 when the snow melts.
[0019] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
