Problems solved by technology

[0006] In order to achieve the above purpose, the present invention provides a soft rock slope semi-rigid retaining structure and its construction method, which is suitable for high slopes and uses graded drainage to achieve the purpose of rapid drainage; at the same time, internal drainage pipes are pre-buried inside the slope , combined with horizontal drainage ditches and vertical drainage channels, can effectively drain the surface water of the slope, and solve the problem that the existing slope treatment technology is prone to weathering and disintegration of the surface rock of the slope, and the internal rock and soil of the slope generally have the problem of easy disintegration when encountering water. Problems of softening and creep deformation

Abstract

The invention discloses a soft rock side slope semi-rigid retaining structure and a construction method thereof. The soft rock side slope semi-rigid retaining structure comprises a drainage system which comprises a torrent groove, a slope bottom drainage ditch, a plurality of transverse drainage ditches, a plurality of longitudinal drainage channels and a plurality of drainage pipes; an anchoring system which comprises a cast-in-place concrete structure fixed on each stage of side slope platform and a plurality of anchor rods which are uniformly distributed on each stage of side slope platform at certain intervals; and a greening system which is arranged on a surface of an artificial slope and consists of greening blocks arranged in grids formed by interweaving a plurality of longitudinal drainage channels and a plurality of transverse drainage ditches. The soft rock side slope semi-rigid supporting and retaining structure and the construction method thereof are suitable for high side slopes, and a purpose of rapid drainage is achieved through graded drainage; and meanwhile, internal drainage pipes are pre-buried in the side slope and matched with transverse drainage ditches and longitudinal drainage channels, so water on the surface of the side slope can be effectively drained.

Description

technical field [0001] The invention belongs to the technical field of slope treatment, and relates to a soft rock slope semi-rigid retaining structure and a construction method thereof. Background technique [0002] With the development of my country's national economy, especially the construction of infrastructure such as hydropower projects, railways, highways and mining projects, a large number of exposed rock slopes will appear in these projects. Because rocky slopes generally have well-developed joints, no vegetation on the slope surface, high slope height, and severe weathering, under the action of wind and long-term rain erosion, rockfalls often occur; Generally, it has the characteristics of easy disintegration and softening when exposed to water, and large creep deformation. Under the long-term action of hot and humid environment, the shear strength of the soil body decreases rapidly. , have a significant impact on the stability of rock slopes. The surface of the...
