Step 2: completing the assembly of entire grid
A) position that grid longitudinal rib is marked first on grid cross rib, is then successively inserted perpendicularly into longitudinal row for grid cross rib Hole of the water with side, and melting welding is adhesively fixed in intersection;
B) grid longitudinal rib is laid on the position that grid cross rib marks in advance, the two is viscous using melting welding at crossover location It connects, a kind of TGXG with drain function is finally made.
The present invention has following technological merit:
1. the present invention is made of grid cross rib, grid longitudinal rib and longitudinal drainage band, wherein grid cross rib and longitudinal rib are soil Work band not only has the function of excellent reinforcement, but also has efficient drainage performance.
2. being disposed with suction water cellulose inside longitudinal drainage band, wherein suction water cellulose is made of hydrophilic hygroscopic materials, With a large amount of fine drainage channels, water is sucked out from soil for elder generation, and then the water of suction is discharged along its internal drainage channel The soil body, therefore improve the discharging water efficiency of longitudinal drainage band.
3. longitudinal drainage band is fabricated to flat, its contact area with soil is increased, longitudinal drainage band is conducive to Draining.
4. being evenly arranged with vertical supporting plate inside longitudinal drainage band, it is enough anti-not only to ensure that longitudinal drainage band has Pressure energy power will not be subject to crushing during compacted subgrade, it is thus also avoided that its internal suction water cellulose is crushed, and then influences Its discharging water effect.
5. being provided with buckle structure and water suction cotton pad at longitudinal drainage band both ends, it can easily connect muti-piece and drain geotechnological lattice The longitudinal drainage band of grid, forms unobstructed drainage channel, therefore facilitate site operation, enhances the practical of drainage geogrid Property.
