Problems solved by technology

[0005] The present invention aims to solve and overcome the problem that the existing flexible retaining net cannot make full use of the strength of the loose rock and soil itself and the overall internal force of the flexible retaining net when impacted, and provides a structural layout that is reasonable and can fully utilize the loose rock The rock-soil body that blocks the movement by the strength of the soil itself and the flexible retaining net that systematically reduces the internal force of the structure and its design method

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as figure 1 As shown, the flexible retaining net of the present invention includes a support column 1 , a support rope 2 , a metal flexible net 3 , an anchor rope 4 , an energy dissipation device 5 and a short anchor rod 6 .

[0041] The support column 1 includes two end support columns 11 and a middle support column 12 between the two end support columns 11. In order to ensure the balance state of the support column 1 in space, the end support columns 11 and the middle support column 12 The top of the top is connected to the pull anchor rope 4 inclined to the top of the slope; the support column 1, that is, the end support column 11 and the middle support column 12, are all composed of a support column main body and a support column base hinged at the bottom end of the support column main body.

[0042]The support rope 2 is connec...

Abstract

The invention relates to a flexible barrier net and a design method thereof. The flexible barrier net includes main components such as a supporting column, a supporting rope and a metal flexible net.The supporting column is formed by a supporting column main body and a supporting column base. The supporting rope includes a longitudinal supporting rope, a top supporting rope, an intermediate supporting rope and a diagonal supporting rope connected between the supporting column and the metal flexible net. The lower part of the metal flexible net is arranged obliquely downstream of a slope; themetal flexible net is in a relaxed state when not impacted, the position of the bottom of the metal flexible net is fixed through a short anchor rod, and the bottom of the metal flexible net has redundancy and is folded in the upstream direction or embedded inside a slope body. The flexible barrier net is reasonable in structure, and the strength of loose rock and earth mass can be fully used to block moving rock and earth mass and systematically reduce the structural internal force.

Description

technical field [0001] The invention relates to a flexible protective structure, in particular to a flexible retaining net for retaining moving loose rock and soil bodies, especially mud-rock flows and collapse debris flows, and a design method thereof. Background technique [0002] Compared with the rigid reinforced concrete retaining structure, the flexible retaining net has many advantages such as excellent deformation buffering performance, good water permeability, convenient construction and installation, and environmental friendliness. It has been widely recognized in the fields of geological disasters, transportation, and mining. Existing flexible retaining mesh finalized products are derived from the demand for rockfall protection, mainly including high-strength metal flexible mesh, support columns, support ropes, anchor ropes, energy-dissipating devices and corresponding fixed foundations. In practical application, it is found that the flexible retaining net for roc...
