Problems solved by technology

However, due to the complex terrain and geological conditions in mountainous areas, large changes in rainfall intensity, incomplete technical system, time-consuming and labor-intensive factors, the efficiency of rainwater collection and utilization are both low, and ultimately the rainwater storage and utilization technology is widely used in mountainous areas. Not very widely used
Especially in the aspect of steep rocky mountains, because the traditional water storage device is located on the surface of the mountain and lacks a reasonable location, the application is even more lacking.

Embodiment 1

[0044] The construction method of rainwater external collection and internal storage system facing steep rocky mountains. For rocky mountains that cannot be used for rainwater storage due to steep slopes, rainwater collection surfaces, confluence ditches, sedimentation tanks and storage tanks are constructed from the top of the mountain; A trash rack for filtering and removing impurities is built between the confluence ditch and the sedimentation tank; impurities include litter, fallen leaves, sand and gravel; the confluence surface directly adopts the natural slope of a steep rocky mountain; the confluence ditch includes agricultural ditches, bucket ditches, The branch ditches and main ditches form a tree-like branch structure; the agricultural ditches are distributed in contour lines in the vertical direction and inverted slopes in the horizontal direction. The main channel leads to the sedimentation tank; the sedimentation tank is located at the end of the confluence ditch a...

Embodiment 2

[0047] The width of the confluence ditch is 30-50cm, the depth is 30-50cm, the vertical distribution is parallel to the contour line, the longitudinal slope is 1 / 500-1 / 300, and the horizontal slope is 5-10°; the bucket of the confluence ditch The width of the ditch is 50-80cm, the depth is 30-50cm, the longitudinal direction is perpendicular to the contour line, and the longitudinal slope depends on the terrain; The high lines are distributed in parallel, and the longitudinal slope is 1 / 500-1 / 300; the width of the main ditch of the confluence ditch is 100-120cm, and the depth is 50-60cm. The longitudinal direction is perpendicular to the contour line, and the longitudinal slope depends on the terrain.

Embodiment 4

[0049] The upper part of the cross-section of the water storage cellar is a semicircle, and the lower part is a rectangle, and the diameter of the upper semicircle is the same as the long side of the lower rectangle; for the water storage cellars whose rock structure stability is not up to standard, the reinforcement treatment shall be carried out as follows: Reinforce the upper part of the water storage cellar with anchors, steel rings, and corrugated steel plates; for the water storage cellars whose rock permeability does not meet the standard, anti-seepage treatment shall be carried out as follows: Lay anti-seepage at the bottom and side walls of the water storage cellar. Seepage membrane, impermeable cloth, impermeable board.

Abstract

The invention discloses a method for constructing a rainwater external collection and internal storage system for a steep stony mountain, and aims to solve the problem that rainwater collection and storage cannot be carried out on the stony mountain due to a steep slope of the mountain. According to the method, a rainwater collection surface, a confluence ditch, a sedimentation tank and a water storage cellar are constructed from the top of the mountain to the bottom, wherein the rainwater collection surface directly adopts a natural slope of the steep stony mountain, the confluence ditch comprises sub-lateral ditches, lateral ditches, branch ditches and a trunk ditch to form a tree-shaped branch structure, the sub-lateral ditches are longitudinally distributed in a contour line mode and transversely distributed in an inverted slope mode, the plurality of sub-lateral ditches converge to the lateral ditches, the plurality of lateral ditches converge to the branch ditches, the pluralityof branch ditches converge to the trunk ditch, the trunk ditch converges to the sedimentation tank, the sedimentation tank is positioned at the tail end of the confluence ditch and the front end of the water storage cellar, and the water storage cellar is constructed in a mountain body by adopting a rock mass excavation operation method according to the standards of deep hole digging, wide water collection, annual regulation and normal water supply. According to the method, the technical bottleneck of water conservancy development of the steep stony mountain is broken through.

Description

technical field [0001] The invention relates to the technical field of small-scale water conservancy projects for rainwater collection and storage, in particular to a brand-new construction method for rainwater external collection and internal storage system for rocky mountains that cannot collect rainwater due to steep slopes. Background technique [0002] With the rapid development of social economy and the influence of global climate change, our country and even the whole world are facing more and more pressing challenges of water problems. Among them, water resource shortage, water environmental pollution, water ecological degradation, flood and drought disasters and other issues have seriously threatened social and economic development, human health, living environment and national security. [0003] Water is the source of life, the key to production, and the foundation of ecology. Water is the main component of all living organisms, and it also has many physiological f...
