Efficient water suction and drainage device for slope rock soil

Abstract

The invention discloses an efficient water suction and drainage device for slope rock soil. The efficient water suction and drainage device comprises a rock soil slope, wherein a main drainage channel and a slope drainage channel are formed in the inclined side of the rock soil slope; a plurality of slope water inlet pipes are arranged at the bottom end of the slope drainage channel; the ends, away from the slope drainage channel, of the slope water inlet pipes communicate with a water storage cavity; a plurality of water suction systems are fixedly arranged on the side, away from the slope water inlet pipes, in the water storage cavity; and a plurality of water storage plug systems are connected to the bottom end in the water storage cavity. According to the efficient water suction and drainage device, the slope drainage channel is formed in the middle of the slope so that erosion of rainwater scouring to the slope soil can be reduced, meanwhile, water in the rock soil enters the water suction systems through water suction and drainage materials, capillary channels have the capillary suction force effect, the water in the rock soil can be actively sucked into capillary cavities through the water suction and drainage materials and then is drained into the water storage cavity, a siphon, the water storage plug systems and a water outlet plug system can guarantee the stability of the water amount in the water storage cavity, and soil loss cannot be caused while supply of water of vegetation on the surface of the soil is guaranteed.

Description

technical field [0001] The invention relates to the technical field of suction and drainage, in particular to a high-efficiency suction and drainage device for slope rock and soil. Background technique [0002] The side slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. [0003] At present, the damage to the slope caused by rainfall infiltration has become one of the serious threats in highway engineering. Rainfall, especially heavy rainfall, will cause the rock and soil of the slope to absorb water and expand. On the one hand, the hardness of the rock and soil will be reduced, and on the other hand, the soil will be loosened, which will cause serious soil loss under the erosion of rainwater. [0004] The patent number is 201910366393.0. The authorized patent document discloses a high-efficiency suction and drainage pipe used inside the rock and soil mass. The water in the water is quickly discharged, wi...

Problems solved by technology

[0005] Although the above-mentioned patent documents provide a suction and drainage device that can quickly absorb moisture in the soil, the device can only absorb moisture and cannot store moisture, resulting in a lack of moisture in the soil in the rock and soil. Although the hardness of the rock and soil can be guaranteed, the edge The vegetation on the slope cannot survive naturally. When heavy rainfall comes, the rainwater will wash away the soil without vegetation protection, and there will be soil loss, which will cause serious damage to the slope structure in the long run
