Abstract
The utility model provides a high-strength punched and welded earthwork lattice room and relates to the technical field of civil engineering. The high-strength punched and welded earthwork lattice room mainly consists of a plurality of polyethylene plates which are welded to form a three-dimensional lattice room structure through ultrasonic wave, the polyethylene plates are high-density polyethylene plates and are subjected to melting extrusion and drawing to form high-strength plates with low expansion and contraction ratio, the surfaces of the polyethylene plates are provided with a plurality of penetrating hole regions at equal intervals, and the penetrating hole regions are provided with a plurality of holes. The surfaces of the polyethylene plates are provided with the holes, so that the flexibility of the polyethylene plates is improved, pull crack phenomena caused by pulling during earthwork lattice room construction are effectively decreased, and the using quality of the earthwork lattice room is guaranteed.
Description
Technical field
The utility model relates to technical field of civil engineering, is specifically related to a kind of punching welding High strength geogrid.
Background technology
Geotechnical grid, has netted lattice cell structure, and it is capable of expansion and contraction, during transportation, can contract and gather into folds, and opens and filling soil stone or concrete material again during use, forms the structure with powerful lateral limitation and large rigidity.Be widely used in firm highway, railway bed; Bearing dyke and the shallow water river channel of carrying force administers; Prevent landslide and be subject to the hybrid barricade of carrying force; When running into subgrade, adopt geotechnical grid can greatly alleviate construction labour intensity, reduce roadbed thickness speed of application fast, performance is good, reduces greatly construction costs.
But current geotechnical grid is all a kind of three-dimensional netted lattice cell structure that polyethylene sheets is formed through high-tenacity welding, the geotechnical grid pliability of this structure is poor, during construction, need to stretch to two side stretching limits of geotechnical grid, because pliability is poor, easily there is drawing crack phenomenon, affected the use of geotechnical grid.
Utility model content
The utility model provides a kind of punching welding High strength geogrid, the poor problem of pliability existing to solve prior art.
The utility model is mainly comprised of some polyethylene boards, through supersonic welding, be connected into three-dimensional netted lattice cell structure, solving the technical scheme that its technical problem adopts is that polyethylene board is Hdpe, through melt extruding drawing-off, become the sheet material of the low expansion and contraction of high strength, polyethylene board surface is equidistant arranges some punch blocks, and punch block arranges some holes.
The utility model, by some holes being set on polyethylene board surface, has improved the pliability of polyethylene board, effectively reduces the drawing crack phenomenon causing due to stretching while knowing clearly geotechnical grid construction, has ensured the service property (quality) of geotechnical grid.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1 polyethylene board, 2 punch blocks, 21 holes in figure.
The specific embodiment
A kind of punching welding High strength geogrid, mainly by some polyethylene boards 1, formed, through supersonic welding, be connected into three-dimensional netted lattice cell structure, polyethylene board 1 is Hdpe, through melt extruding drawing-off, become the sheet material of the low expansion and contraction of high strength, polyethylene board 1 surface is equidistant arranges some punch blocks 2, and punch block arranges some holes 21.
Claims (1)
1. High strength geogrid is welded in a punching, mainly by some polyethylene boards, formed, through supersonic welding, be connected into three-dimensional netted lattice cell structure, it is characterized in that polyethylene board is Hdpe, through melt extruding drawing-off, become the sheet material of the low expansion and contraction of high strength, polyethylene board surface is equidistant arranges some punch blocks, and punch block arranges some holes.
