Abstract
The invention relates to a ribbed high-strength geotextile prepared from a flexible polyethylene net (2) and reinforcing ribs (1). The ribbed high-strength geotextile is characterized in that the reinforcing ribs (1) are in a grid shape, the flexible polyethylene net (2) is paved on and connected with the reinforcing ribs (1) into a whole, the reinforcing ribs (1) are integrally extruded and formed into a sheet grid, and the polyethylene net (2) and the reinforcing ribs (1) are ultrasonically welded and formed into a whole. The geotextile of the invention has high overall strength and low elongation as well as prolonged service life because the friction between the geotextile and the foundation is reinforced by convex and concave surfaces formed by the reinforcing ribs and the flexible polyethylene net.
Description
Technical field
The present invention relates to the construction project field, specifically be applied to the protection of railway, highway slope, a kind of reinforcement high strength geotextiles in field such as stabilization of dam foundation in the hydraulic engineering.
Background technology
Geotextiles is a kind of ground stabilization material that is applied to fields such as railway, highway, hydraulic engineering.Mainly act as treatment of soft foundation, slope protection etc.The present domestic multiple composite earthwork cloth of having invented, purpose all are for the tensile strength that strengthens geotextiles, reduce elongation per unit length, prolong the application life of geotextiles.Chinese patent application number is " 94207066 ", name be called " geotextiles " patent disclosure the geotextiles that is composited mutually of a kind of fibrage and polythene net, purpose is the intensity that strengthens geotextiles, reduce elongation per unit length, but fibrage and polythene net all belong to soft material, still have defectives such as easy displacement in the application on railway, highway slope and dam foundation slope.
Summary of the invention
The objective of the invention is to invent a kind of reinforcement high strength geotextiles, the reinforcing rib of this geotextiles adopts the polypropylene material extrusion modling and plays the effect of high strength skeleton, and it is online that the process supersonic welding is connected on soft polyethylene again.
Technical scheme of the present invention is:
A kind of reinforcement high strength geotextiles comprises soft polythene net and reinforcing rib, and described reinforcing rib is that latticed, soft polythene net is laid on the reinforcing rib, and binding is an integral body.
Described reinforcing rib is the sheet grid of monolithic extruded moulding.
Described polythene net and reinforcing rib adopt ultrasonic bonding to be shaped to an integral body.
The invention has the beneficial effects as follows:
Geotextiles bulk strength height of the present invention, elongation per unit length is low, because the male and fomale(M﹠F) that reinforcing rib and soft polyethylene net are combined to form has strengthened the frictional force of geotextiles and ground, has prolonged the application life of geotextiles.
The soft polyethylene net and the reinforcing rib of geotextiles of the present invention form by ultrasonic bonding, and it has overcome, and common geotextiles tensile strength is low, and elongation per unit length is big, with defectives such as foundation material frictional force are little, have and make simply, and intensity is big, advantages such as long service life.Be applicable to the slope protection in the engineerings such as railway, highway, water conservancy.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 is that polythene net, 2 is reinforcing rib.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
A kind of reinforcement high strength geotextiles comprises soft polythene net 2 and reinforcing rib 1, and described reinforcing rib 1 is that latticed, soft polythene net 2 is laid on the reinforcing rib 1, and binding is an integral body.
Reinforcing rib 1 is the sheet grid of monolithic extruded moulding.Through the monolithic extruded one-tenth trellis of equipment, polythene net 2 and reinforcing rib 1 adopt ultrasonic bonding to be shaped to an integral body to reinforcing rib 2 by polythene material.
Claims (3)
1. a reinforcement high strength geotextiles comprises soft polythene net (2) and reinforcing rib (1), it is characterized in that described reinforcing rib (1) for latticed, and soft polythene net (2) is laid on the reinforcing rib (1), and is connected to an integral body.
2. reinforcement high strength geotextiles according to claim 1 is characterized in that described reinforcing rib (1) is the sheet grid of monolithic extruded moulding.
3. reinforcement high strength geotextiles according to claim 1 is characterized in that described polythene net (2) and reinforcing rib (1) adopt ultrasonic bonding to be shaped to an integral body.
