Abstract
A high-strength steel-plastic geocell is formed by punching high-strength geocell sheets which are provided with ribs, connecting the punched high-strength geocell sheets via stainless steel rivets and then drawing. The high-strength steel-plastic geocell is characterized in that each geocell sheet consists of a substrate and ribs, and the ribs are arranged in the substrate. The substrate is made of high-density polyethylene and the ribs are made of steel wires. Strength of the geocell sheet can be equal to or higher than 300 MPa, and breaking elongation rate of the geocell sheet is lower than or equal to 3%. The ribs such as steel wires with low elongation are added in the substrate, thereby being capable of increasing strength greatly and improving performance and tension strength of the geocell fundamentally.
Description
Technical field
The utility model belongs to the geo-grid application, and specifically a kind of high strength steel that is applied to reinforce under the grounds such as railway, highway is moulded geotechnical grid.
Background technology
The common plastics geotechnical grid is a kind ofly to be connected through methods such as ultra-sonic welded by the thermoplastic sheet, be cellular stereoscopic grid after the expansion, it utilizes three-dimensional lateral confinement principle, can constitute the different cohesions of looking with fillers such as soil, sand, stone, in order to subgrade strengthening, the side slope protection of Rail Highway, build barricade etc.The tensile fracture of the unit width of this geotechnical grid sheet is little, and the elongation at break of lattice chamber sheet is big, the geotechnical grid behind existing now a kind of drawn, and lattice chamber sheet sheet strength is more than or equal to 150MPa, and the elongation at break of lattice chamber sheet is smaller or equal to 15%.Be difficult to satisfy the actual needs that use.
Summary of the invention
The purpose of this utility model provides a kind of high strength steel and moulds geotechnical grid, to overcome above-mentioned drawback.
The technical solution of the utility model is: a kind of high strength steel is moulded geotechnical grid, connects drawn by the high strength geotechnical grid sheet punching back of containing the muscle band with stainless steel rivet and is shaped, and described geotechnical grid sheet is made up of base material and muscle band, and the muscle band is arranged in the base material.
The material of described base material is a high density polyethylene (HDPE).
The material of described muscle band is a steel wire.
The beneficial effects of the utility model are:
Lattice of the present utility model chamber sheet strength can be more than or equal to 300MPa, and the elongation at break of lattice chamber sheet is less than or equal to 3%.Add muscle materials such as low elongation steel wire in the base material, can improve intensity greatly, improve the performance and the tensile strength of geotechnical grid at all.
Description of drawings
Fig. 1 is a cross section of the present utility model sectional structure schematic diagram.
Among the figure: 1 is that geotechnical grid sheet, 2 is that base material, 3 is the muscle band.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of high strength steel is moulded geotechnical grid, connects drawn by the high strength geotechnical grid stainless steel rivet that contains muscle band 3 and is shaped, and described geotechnical grid sheet 1 is made up of base material 2 and muscle band 3, and muscle band 3 is arranged in the base material 2.
The material of base material 2 is a high density polyethylene (HDPE).
The material of muscle band 3 is a steel wire.Muscle band 3 can staggered or parallel arrangement.
Can earlier muscle band 3 be arranged, and then the base material 2 of burden high density polyethylene (HDPE) material on it.
Muscle band 3 can longitudinally be arranged in base material 2, and muscle band 3 selected gauge of wire and quantity can be according to actual mode of occupation adjustment.
At last, geotechnical grid sheet 1 is coupled together, one group of bar shaped geotechnical grid sheet 1 that connects is launched along its vertical direction, form latticed three-dimensional lattice chamber by connecting folder.
During use, one group of geotechnical grid sheet 1 main body that connects is launched along axis direction, and then the suitable as required filler compactings such as sand, soil or rubble of filling out get final product.
