Embodiment

[0030] Such as figure 1 and 2 As shown, the active-passive hybrid trailing high-performance protective net includes a column 1, an intercepting mesh 2, a trailing mesh 3, multiple parallel support ropes 4, energy dissipation devices 5, anchor ropes 6, and end support ropes 7 , wherein several columns are arranged at intervals, the uppermost parallel support rope is hung on the top of all columns, and the lowermost parallel support rope is at a certain height from the ground, so as to reserve the opening space for falling rocks to pass through, and hang on the lower part of the column; The mesh is hung on multiple parallel support ropes, and both sides are hung on the end support ropes; the upper end of the trailing mesh is connected to the lower end of the intercepting mesh, and the lower end is freely placed on the slope; After the column passes through, it extends outward and is anchored on the supports at both ends; the anchor rope is tied to the upper end of the column an...

Abstract

The invention discloses an active and passive combined trailing high-performance protective screen. Multiple parallel supporting ropes are adopted to replace traditional up-down supporting ropes; the lowermost parallel supporting rope is lifted a certain distance away from the ground to form a lower open space which falling stone can pass through, so that a system has the open characteristic, and the falling stone can enter a trailing mesh area conveniently; meshes are divided into intercepting meshes and trailing meshes to enable the falling stone with a certain size to enter the trailing mesh area, after the falling stone is intercepted, through the open space at the lower portion of the lowermost parallel supporting rope and move to a prearranged collection area in the trailing direction; the trailing meshes can, to some extent, control the track of collapsed falling stone in a covered area. The active and passive combined trailing high-performance protective screen adopts the advantages of an active protective screen system and the advantages of a passive protective screen system, thereby having a high protection level and being easy to clean.

Description

technical field [0001] The invention relates to a flexible protection net with both passive interception and active control functions, in particular to an active and passive hybrid trailing high-performance protection net, which belongs to the field of disaster prevention structures. Background technique [0002] In recent years, rockfall on slopes has posed a serious threat to traffic safety and life and property safety, and flexible protective nets are usually used for prevention and control. Existing flexible protection systems are mainly divided into active flexible protection net systems and passive flexible protection net systems. [0003] The active protection system is covered with various types of flexible nets mainly made of steel wire rope nets and wrapped on the required protective slopes or rocks to limit the weathering, spalling or damage of rocky soil on the slope and the collapse of dangerous rocks (reinforcement), or to control rockfall Movement within a ce...
