Steep slope protective soft frame and construction method thereof

Abstract

The invention discloses a steep slope protective soft frame, wherein a first layer of soft frames is laid at the bottom of a steep slope, and a second layer of soft frames is laid above the first layer of soft frames by 20-40cm until the top of the slope. The first layer of soft frames is formed by the soft frames which are connected with one another and are fixed on the steep slope, each soft frame is formed in the way that: a frame is arranged at the back side of a panel, the bottom of the panel is fixed on the steep slope through a connection part, an overlap piece is respectively arranged at the left and the right sides of the panel for overlapping one panel with the adjacent panel, two sides of the upper and the lower frames of the back side of the panel are respectively provided with a mounting groove which has a clapboard inside, a shaft sleeve is arranged at the upper end of the clapboard, an anchor rod arranged in the shaft sleeve is fixed on the steep slope, soil is filled at the back side of the panel, and plants are grown on the back side of the panel. The construction method comprises steps of clearing up a sloping surface and laying the soft frames. The steep slope protective soft frame has the advantages of long service life, low maintenance cost, optimized environment of the steep slopes of two sides of a road and the like, and the steep slope protective soft frame can be applied for the steep slope protection of the two sides of railways, highways, mines, hydropower and other projects.

Description

technical field [0001] The invention belongs to the technical field of ecological protection and management in civil engineering, and in particular relates to the ecological management of steep vegetation slopes. Background technique [0002] In the construction of railways, highways, hydropower and other projects, it is often necessary to excavate a large number of slopes. The excavated slopes are eroded and damaged by wind and rain, resulting in instability, collapse and other diseases, and the excavation of the slopes destroys the original vegetation. Overburden, resulting in a large number of secondary bare land and serious soil erosion, affecting the ecological balance. With the strengthening of human awareness of environmental protection, ecological protection has become a development trend. At present, the commonly used methods of slope greening include reinforced concrete frame method, vegetation roll bedding method, alien soil vegetation belt method, fiber greening...

AI Technical Summary

Problems solved by technology

Because the flexible protection belt is very long, the soil filled behind the flexible protection belt is relatively heavy, and the flexible protection belt will be crushed in a short time, and the service life is very short, which increases the maintenance cost of the road, and for roads above 60° Steep slope, due to the low strength of the flexible protective belt, the long length of the flexible protective belt, and the heavy weight of the filling soil on the back of the flexible protective belt, this kind of flexible protective belt is not suitable for use on steep slopes
