The two-way geogrid and slope are vertical and laid on flat and hard filler to prevent overlap, bending and direct contact.
High frequency vibration mode cannot be selected in steel rolling project, but static pressure shall prevail and medium and low speed shall be adopted.
By reasonably applying two-way geogrid reinforced gravel pile to soft foundation treatment, the foundation bearing capacity can be effectively improved and good construction effect can be achieved.
When placing a two-way earthwork grid, you can select the overlapping method for two adjacent vertical connections, and 0.25cm is the overlapping width.

Two way geogrid reinforcement materials with uniform stability and high strength can be selected to form various coarse-grained soils and reinforced layers, and good reinforcement effect can be achieved.
At the same time, the reinforced earth embankment and embankments on both sides shall be constructed, and the connection position shall be constructed reasonably.
Before laying two-way geogrid, various construction materials shall be checked to ensure that they meet the design requirements.
It is not easy to use the hole forming process that causes damage to the large-scale two-way geogrid around the pile by using pile sinking, impact hole driving pile, long spiral pile, etc.

Therefore, the overall construction quality of the gravel pile shall be fully understood according to the actual situation of the geogrid construction unit.
The main inspection items include porosity, elongation, durability, etc.

After laying earthwork synthetic materials, charging works shall be carried out immediately, and long-term exposure of materials is strictly prohibited.
According to the design length requirements, the blanking construction of two-way earthwork grid shall be strictly controlled, and it is required to increase about 300 ~ 500mm.

During the construction of manual hole digging pile, the two-way geogrid is cut and poured into the pile, which will not have an adverse impact on the safety and stability of the slope.
For the backfill area with two-way geogrid reinforcement belt, the adverse impact of pile foundation selection on two-way geogrid shall be considered.
The geogrid has soft soil road, which is to effectively improve the foundation bearing capacity and reduce settlement in the foundation reinforcement project.
When connecting the stress direction of geogrid, the connection strength exceeding the allowable strength shall be controlled in the design.
The cut-off grid in the construction of rotary bored cast-in-place pile can usually increase the grid on both sides of the pile, or leave margin in the grid design.
