Soft Base Processing Specification

Soft Base Processing Specification

Layout the base:

1 Try to use the way of cross-laying, so that the width of each compartment corresponds to the width of the embankment as much as possible, because the two-way strength of the compartment is consistent of the soft base improvement;
The 2 cells are pulled vertically in the direction of the bank axis, and no slack is allowed. It should be manually tightened. The geocell can be sewn as needed;
3 by weighting (referring to the filling in the grid of the marginal compartment) or inserting the nail to position the compartment on processing of the soft ground, without moving due to filling;
4 Check the cell for damage before paving the soft soil. If found, it should be disposed of immediately;
5 After paving the high-strength geocell, it should be filled on the soft base within 48 hours. 

Filling the soil:

A. There should be no slack in the laying of high-strength geotechnical cells, and try to tighten them manually before filling.
B. Fill the soil symmetrically from the center to the sides, and it is inverted U-shaped. The filling is used to keep the high-strength geocells under tension. C. The height of the earth unloading shall not exceed 1m to prevent local subsidence.
D. Pay attention to the size and weight of the PVD construction machinery to avoid the occurrence of ruts larger than 7~8cm. 
E. The filled soil is 50cm after being crushed.
