Description
Technical field
The invention belongs to rock side slope falling rocks guard member field, be specifically related to a kind of wire rope net and comprise other guard members of wire rope net.
Background technology
Wire rope net is made up of wire rope, node connector and wire clips, it is to be twined on mould by a complete wire rope, form the diamond-shaped meshes of certain size, the end of wire rope adopts wire clips to connect, and the node place that wire rope intersects adopts special connector to fix.
What existing wire rope net node connected mode adopted is the cross buckle of galvanizing, its advantage is simple installation, but because existing cross buckle is to adopt the conventional galvanizing preservative treatment, its antiseptic property is relatively poor, intensity is lower, application life, this caused existing wire rope net to be had a greatly reduced quality on range of application and effect far below wire rope itself, the difficult satisfied requirement of putting into practice of protection effect.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, and a kind of labor and material saving, durable in use, the life-span is long, intensity is high wire rope net are provided, and the active protective screening and the falling rocks roll guard that comprise this wire rope net.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is a kind of wire rope net, described wire rope net is the latticed member that is woven into by wire rope, after the node place that described wire rope intersects is closely twined by the mild steel wire that plates the Gao Erfan preservative treatment, form the wire side node connector of a described wire rope net.
In the above-mentioned wire rope net, described wire side node connector preferably includes the Fixed Division, center that is wound in fork position, center, described node place and is wound in that four on the wire rope extend Fixed Divisions around the described node place.
In the above-mentioned wire rope net, described four extension Fixed Divisions preferably are approximate cross symmetric arrangement.
In the above-mentioned wire rope net, the winding number of turns of Fixed Division, described center is preferably 2 circles, and the winding number of turns of each described extension Fixed Division all is preferably 5 circles.
In the above-mentioned wire rope net, the diameter of described mild steel wire is preferably 3.0mm.
As a total technical conceive, the present invention also provides the active protective screening of a kind of massif or geotechnical body, described active protective screening is crisscross be compiled into latticed of longitudinal bracing rope and cross binding rope, the intersection of described longitudinal bracing rope and cross binding rope is provided with anchor pole, and described longitudinal bracing rope is connected with described anchor pole respectively with the cross binding rope and has carried out pre-stretch-draw; Lay an above-mentioned wire rope net in each grid of described active protective screening, every described wire rope net with its around the longitudinal bracing rope and the cross binding rope between sew up and connect and strain with sewing up rope.
Further improvement as the active protective screening of above-mentioned massif or geotechnical body, under described wire rope net, also be equipped with little mesh (relatively initiatively protective screening grid, the concrete aperture of this mesh can be determined according to putting into practice needs) twisted pair hexagon wire lath.
As a total technical conceive, the present invention also provides a kind of falling rocks roll guard, and described falling rocks roll guard mainly is spliced by many above-mentioned wire rope nets, and splicing place of adjacent two described wire rope nets is provided with the connection steel column; The top of described each wire rope net and bottom margin are respectively by a top braces rope and the series connection of bottom support rope, described falling rocks roll guard is provided with affixed many in ground towards a side of side slope and goes up the side slope supporting rope, and the both sides of the edge of described falling rocks roll guard are equipped with lateral support rope and the side direction connection cord affixed with ground.
Preferably, in the above-mentioned falling rocks roll guard, described on each an end of side slope supporting rope be connected in the top of described connection steel column, the other end is fixed in ground.
Preferably, in the above-mentioned falling rocks roll guard, an end of described lateral support rope is connected in the top of outermost described connection steel column, and the other end is fixed in ground; One end of described side direction connection cord is connected in the bottom of outermost described connection steel column, and the other end is fixed in ground.
In the above-mentioned falling rocks roll guard, described going up on side slope supporting rope, lateral support rope and the side direction connection cord all preferably is provided with sinker.
Compared with prior art, the invention has the advantages that:
(1) life-span is long; Wire side node connector in the wire rope net of the present invention adopts plating Gao Erfan preservative treatment, and the plating Gao Erfan amount of wire side node connector is 255g/m
2, the ordinary node connector then generally adopts zinc-plated processing, and its zinc-plated amount is 50 g/m
2～80 g/m
2Some in addition take mopping to carry out the top layer preservative treatment, even under the prerequisite of equal coating amount, the anticorrosion time limit of plating Gao Erfan itself also is 4～5 times of galvanizing amount, as seen, the application life of wire rope net of the present invention is much larger than the application life of ordinary steel wire netting, thereby ensured the application life of overall structure (for example the present invention's active protective screening and falling rocks roll guard) greatly, it belongs to a kind of high-energy wire rope absorption mesh (High-energy absorption nets is abbreviated as HEA).
(2) intensity height; Wire side node connector in the wire rope net of the present invention is to adopt the mild steel wire of plating Gao Erfan closely to twine the node of making, its tearing toughness can reach 24.4KN, and the tearing toughness of prior art employing cross buckle only is that 4.6 KN～13.5KN(quality difference is distinguished to some extent), this is when effectively improving node strength, can also effectively stop between the wire side wire rope changing of the relative positions to take place, thereby increase substantially the integral protection effect of wire rope net.
To sum up, wire rope net of the present invention and other guard members have labor and material saving, long, intensity advantages of higher of durable in use, life-span.
