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

Embodiment 1

[0021] 1. Construction technology of bamboo fan on phyllite waste slag slope without erosion ditch. The slope is relatively flat with no erosion ditch. The deposits on the slope surface are road construction spoils, phyllite debris flakes, slippery, easy to scatter and slide each other; debris is easy to weather, easy to muddy when exposed to water, and under the lubrication of saturated infiltration rainwater, the debris is muddy. creep or collapse along the slope. The average slope of the slope exceeds 35°, and collapsed and scattered remnants can be seen in the steep middle of the slope. Bamboo fan construction steps: 1) Cut bamboo sections 4-7cm thick and 80-100cm long, cut the lower end into a horse-ear shape, add pads to the upper end and ram it into the soil, and leave 30-40cm outside as fan piles. 2) Drill piles in rows along the contour of the slope, with a pile distance of 70-100cm. 3) Thin bamboo poles with a thickness of 1 to 1.5 cm are laid horizontally and sta...

Embodiment 3

[0025] Construction technology of bamboo fan for phyllite rock landslides and sliding slopes. The slope surface is formed by the weathering and slumping of exposed phyllite, which is relatively broken, with a slope of 25°-30° and large fluctuations. The deposits on the slope surface are phyllite debris, flaky, slippery, and easy to fall and slide; the debris is easy to weather and muddy when exposed to water. Under the lubrication of saturated infiltration rainwater, the debris is muddy along the slope direction. Creep or collapse scattered. Bamboo fan construction steps: 1) Cut bamboo sections 4-7cm thick and 80-100cm long, cut the lower end into a horse-ear shape, add pads to the upper end and ram it into the soil, and leave 30-40cm outside as fan piles. 2) Drill piles in rows along the contour of the slope, with a pile distance of 70-100cm. 3) Thin bamboo poles with a thickness of 1 to 1.5 cm are laid horizontally and stacked side by side to form a fan row. The thin bambo...

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...
