Description
Technical field
This utility model relates to side slope protection technical field, particularly relates to a kind of protection network being applicable to side slope protection.
Background technology
In most of mountain areas that vegetation is destroyed or job site, it is often necessary to use guard system and prevent from sending out at any time
The burst dangerous situations such as the Rolling Stone of life, falling rocks, snowslide, mud-rock flow.In guard system main composition part be exactly steel wire grid net or
Wire rope net, steel wire grid net or wire rope net are to use intensity and the most extraordinary extraordinary steel wire of pliability or steel wire rope braiding
Form, during the use of steel wire grid net or wire rope net, connect between needing steel wire grid net or wire rope net two are thrown the net
Tapping into capable fastening to process, traditional mode is to use iron wire to be wound around fastening, or carries out wearing knot with common steel wire or steel wire rope,
But such fastening means easily causes winding steel wire in actual use to be loosened, slides, and construction and installation are extremely slow, are mounted to
This height, in the case of steel wire grid net or wire rope net are by very big impulse force, also exists great potential safety hazard.
Publication No. CN 203947760U, publication date is that the Chinese patent literature on November 19th, 2014 discloses one
Construction safety protection network is installed with fixing buckle, it is characterised in that: this fixing buckle is U-shaped buckle, and this U-shaped buckle is by two
Individual engaging lug and the joint portion composition for two described engaging lugs of connection, described engaging lug has for installing securing member
Installing hole.
Construction safety protection network disclosed in this patent documentation is installed with fixing buckle, after long-time use, U-shaped buckle
Yielding, tightness is deteriorated, it is impossible to bears bigger impulsive force, causes the protection effect of protection network to be deteriorated, there is potential safety hazard.
Publication No. CN 204224998U, publication date is that the Chinese patent literature of on 03 25th, 2015 discloses one
Side slope protective screen, steel cable the many groups woven network unit is formed, and described any one group of network unit includes having
First steel cable of crest and trough and second steel cable with trough and crest, the rhombus limit of described network unit is curved
Shape, it is characterised in that: described network unit also includes keeper, the trough of described first steel cable and the crest of the second steel cable
