Problems solved by technology

[0003] The existing passive protection net uses the toughness of the net itself to buffer and dissipate energy from falling rocks, which is easy to cause damage to the net, and when the force on the net reaches the limit value, it will generate tension on the pillar, resulting in bending and damage to the pillar , cannot be used for a long time

Embodiment Construction

[0042] refer to Figure 1~2 , the present invention provides a technical solution: a landslide and rockfall protective net zipper structure with tough energy dissipation function, which is preset at the bottom of the slope, including:

[0043] The fixing component 1 is configured in multiples and is equidistantly fixed at a position close to the bottom of the slope;

[0044] A pillar 3, hinged on the fixed assembly 1;

[0045] In addition, two groups of support ropes 2 are fixed at the end of the pillar 3 away from the fixing assembly 1, and the ends of the two groups of support ropes 2 away from the pillar 3 are fixed in the slope through anchor rods;

[0046] a wire rope net 4 arranged between said pillars 3; and

[0047] The buffer assembly 5 is configured in multiples and is equidistantly socketed on the pillar 3 .

[0048] In this embodiment, a telescoping ring is fixed at the joint between the supporting rope 2 and the anchor rod to provide stretching resistance for t...

Abstract

The invention discloses a landslide collapse rockfall protective net zipper structure with a tough energy dissipation function, and relates to the technical field of rockfall protection, the landslide collapse rockfall protective net zipper structure is preset at the bottom of a side slope, and the landslide collapse rockfall protective net zipper structure comprises a plurality of fixing assemblies which are arranged and fixed at the positions, close to the bottom, of the side slope at equal intervals, supporting columns hinged to the fixing assemblies, a steel wire rope net, and a plurality of buffer assemblies; two sets of supporting ropes are fixed to the ends, away from the fixing assembly, of each supporting column, and the ends, away from the supporting columns, of the two sets of supporting ropes are fixed into the slope through anchor rods; the steel wire rope net is arranged between the supporting columns; and the multiple buffer assemblies are arranged and are connected to the supporting column in a sleeving mode at equal intervals.

Description

technical field [0001] The invention relates to the technical field of rockfall protection, in particular to a zipper structure of a landslide and rockfall protection net with the function of toughness and energy dissipation. Background technique [0002] The slope is prone to landslides due to the instability of the mountain, which will cause the slope to collapse and cause rockfall, which is prone to danger. Therefore, it is necessary to use the slope protection net. The slope protection net is a protective equipment used in expressway and railway landslides. Classification There are active protection and passive protection. [0003] The existing passive protection net uses the toughness of the net itself to buffer and dissipate energy from falling rocks, which is easy to cause damage to the net, and when the force on the net reaches the limit value, it will generate tension on the pillar, resulting in bending and damage to the pillar , cannot be used for a long time. ...
