Description
Technical field
The present invention relates to technical field of civil engineering, more particularly to a kind of geo-grid reinforcement structure, and in particular to a kind of geotechnique
Compartment band, the production method of band and geotechnical grid.
Background technology
It is inferior soft for processing usually using polymeric synthetic material as geo-grid reinforcement material in civil engineering construction
Soil, swelled ground, sandy soil, marine clay etc., to meet requirement of the engineering construction to ground.These materials mainly include three types：
Geotextiles, GSZ, geotechnical grid.
Geotextiles are earliest geo-grid reinforcement materials, can have very high intensity and relatively low elongation percentage, have been had the disadvantage
Isolate upper and lower layer material entirely, be easily caused to form slide surface, so as to cause reinforcing engineering to fail；GSZ because its have it is very high
Tensile strength and relatively low elongation percentage, in extensively reacting the geo-grid reinforcement engineering for soil, level can be efficiently controlled
Load and deformation, it also has a limitation, be exactly can only dispersion level load, for vertical load can only " hard anti-", easily make
Into single-point destruction, differential settlement is formed, so as to cause engineering to fail.
Geotechnical grid is the new geo-grid reinforcement material for growing up recent years, and it has certain altitude, can be effective
Ground dispersion vertical load, the destruction line of slide for making ground road bed is transmitted toward deep layer, forms " deep ground " effect, reduces uneven
