Method for retarding and scattering running water through bamboo fence

Abstract

The invention discloses a method for retarding and scattering running water through a bamboo fence. The bamboo fence is composed of fence piles and a fence row and used for improving the stability of a slope with exposed soil. The method includes the following steps that 1, bamboo segments 4 cm-7 cm thick and 80 cm-100 cm long are made through cutting, the lower ends of the bamboo segments are cut into a horse ear shape, the upper ends of the bamboo segments are cushioned and rammed into soil, and the exterior of each bamboo segment is retained by 30 cm-40 cm, so that the fence piles are formed; 2, the fence piles are driven into a row along the isoheight of the slope, wherein the distance between the piles ranges from 70 cm to 100 cm; 3, thin bamboo poles 1 cm-1.5 cm thick are transversely placed and stacked side by side to form the fence row, the thin bamboo poles are sequentially interwoven upwards among the fence piles one by one from the ground surface, the top end of the fence row is pressed to make the bamboo poles abut against one another, and then the fence row and the fence piles are firmly bundled through bamboo pieces, wherein the height of the fence row ranges from 10 cm to 20 cm; 4, surface soil above the fence row is arranged to fill the gap between the fence row and the ground; 5, an additional pile is needed at the place where the bamboo fence stretches over an erosion gully, and thin bamboo segments are densely arranged to serve as auxiliary pipes till the gully is full of the thin bamboo segments in the width direction, wherein the pile body is higher than the edge of the gully by 30 cm.

Description

technical field [0001] The invention relates to a method for stagnating runoff, in particular to a method for stagnating runoff by using a bamboo fan. Background technique [0002] Runoff refers to the flow of rainfall and snowmelt water flowing along the surface or underground under the action of gravity. Runoff can be divided into surface runoff and underground runoff according to the flow mode, and surface runoff can be divided into slope flow and channel flow. Runoff erosion carries sediment, causing soil erosion and deterioration of the ecological environment. Excessive seepage runoff is prone to occur on bare soil slopes. It is planar runoff at the beginning of its formation, and soon develops and converges into gullies, starting the process of gully erosion. The eroded slope surface forms a network of rills, and then the rills converge in turn to form shallow rills. , Cut the ditch, so that the slope is covered with tree-like erosion ditch systems. Once the erosion...

Problems solved by technology

On steep slopes, the upturned soil is easy to slip and fall apart, making it difficult to achieve the goal of site preparation

Second, the thickness of the soil layer must meet the requirements for site preparation. If the soil layer is too thin, it is impossible to take measures for site preparation.

After the "5.12" earthquake, Mianzhu, Sichuan adopted Japanese mountain treatment techniques to restore post-disaster forest vegetation. The comprehensive reinforcement works include stone ladder engineering, earth bag ladder engineering, earth bag canal system engineering, wire cage retaining wall engineering, and wooden and bamboo fences Remarkable results, but high cost
