Ditch pipe network protection body for slope protection and collapsing hill drainage and soil fixation

Abstract

The invention relates to a ditch pipe network protection body for slope protection and collapsing hill drainage and soil fixation. The ditch pipe network protection body for slope protection and collapsing hill drainage and soil fixation can be produced easily in a shaping mode and can be combined, assembled and constructed easily in the open air. According to the technical scheme, the ditch pipe network protection body for slope protection and collapsing hill drainage and soil fixation comprises an upper intercepting ditch which is formed in the top of a slope, a plurality of middle horizontal water guiding ditches which are sequentially formed downwards at intervals from the top of the slope, a lower drainage ditch which is formed in the bottom of the slope and a plurality of vertical drainage pipes which are arranged in parallel at intervals on the slope surface; the upper end and the lower end of each vertical drainage pipe are communicated with the upper intercepting ditch and the lower drainage ditch respectively, and each vertical drainage pipe is sequentially communicated with the middle horizontal water guiding ditches from top to bottom.

Description

technical field [0001] The invention relates to a technique for controlling water and soil loss, in particular to a ditch pipe network protection body used for slope protection and collapsed hill drainage and soil consolidation. Background technique [0002] The vast area of ​​hilly areas in our country, coupled with the rapid development of housing construction, transportation, and the expansion of various mining area development projects in recent years, has further aggravated soil erosion, which is widely distributed in various provinces, autonomous regions, and municipalities directly under the central government in our country. It leads to the reduction of cultivated land, land degradation, exacerbation of flood disasters, deterioration of the ecological environment, and serious harm to the development of the national economy and the production and life of the people. It has become the number one environmental problem in my country. [0003] During the roadbed, mine con...

Problems solved by technology

[0004] However, the above methods all adopt the rainwater diversion and drainage measures of the masonry concrete upper intercepting ditch and the lower side ditch of the water conservancy project. Its function is mainly to protect the whole project slope protection from hydraulic erosion. , the project cost is high, and new soil erosion is easy to occur outside the slope protection, and there is a lack of water erosion control measures

At the same time, none of the above methods consider the interaction between water flow and soil, and their protection of soil mainly depends on plant restoration.
