Abstract
The utility model relates to a net for protecting the top and the flank of the tunnel for mines, composed of net sections and nodes. The net section is crossing. The intersections are fixedly connected by the nodes. The net section and the node form the mesh. The corner of the mesh is in an arc shape. The utility model has the advantages of low cost, corrosion resistance, fixed connection between the net section and the mesh, and convenient application and maintenance.
Description
The utility model relates to a kind of net of protecting mine laneway top, nation, be specially adapted to the colliery preparatory working Hu Ding, protect nation.
In mine laneway, enter in the tunnel for pressing the fractured rock or the coal fragment that cause with preventing, need lay catch net in the outside of support.At present; the catch net that in coal mine roadway, uses; mainly be that gauze wire cloth is knitted and formed as footpath, weft knitting with steel wire; mesh is a square; steel radial and transverse steel wire intersection are unfixing; the shortcoming of this background technology: the working service inconvenience is easily moved in price height, the stressed back of perishable, steel wire.
The purpose of this utility model is to avoid the shortcoming of background technology, proposes a kind of inexpensive, corrosion-resistant, a net burst cross fixation, a kind of easily plastics catch net of working service.
The utility model employing is fire-retardant, anti-static plastic is manufactured, and its structure is formed by netting thigh and anastomose, and the net thigh is two kinds of tiltlers that direction is vertical, and the intersection is an anastomose, nets thigh and web frame diamondwise mesh, and four angles of diamond-shaped meshes are circular arc.
The utility model is compared with background technology, its advantage:
1) price is low, has only 1/3rd of gauze wire cloth price;
2) corrosion-resistant, life-span long, press little local use can also reclaim multiplexing on ground;
3) net thigh and anastomose are fixing overall structure, and mesh is fixed, and has improved security reliability;
4) light weight, easily cutting, use, maintenance, convenient transportation have alleviated working strength of workers.
Accompanying drawing 1 is a planar elevation view of the present utility model;
Accompanying drawing 2 is the A-A sectional view of Fig. 1;
Accompanying drawing 3 is the B-B sectional view of Fig. 1.
That net strand and anastomose adopt is fire-retardant, anti-static plastic is manufactured, and net strand 1 is for intersecting body, and its angle is 90 degree, and the intersection is an anastomose 2, and the net thigh that intersects is fixed together.Net strand 1 and net strands 2 constitutes diamond-shaped meshes 3, and four angles of rhombus are circular arc, and net strand is ellipse with the cross section of anastomose.
Claims (3)
1, a kind of mining plastics retaining wall net is by orthogonal net burst (1) formation, and it is characterized in that: net strand (1) is by intersection body fire-retardant, that anti-static plastic is made, has anastomose (2) affixed in the intersection, net thigh and web frame diamondwise mesh (3).
2, mining plastics retaining wall net according to claim 1, the bight that it is characterized in that diamond-shaped meshes is a circular arc.
3, mining plastics retaining wall net according to claim 1 and 2 is characterized in that the cross section of net strand (1) and anastomose (2) is ellipse.
