Geogrid construction process

Detect and clean the lower bearing layer → manually lay the Geogrid → lap, tie, fix → spread the upper roadbed soil → crush → test,

The geogrid is laid on the flat lower bearing layer according to the width required by the design. The upper and lower layers of the packing do not smash the debris of the geogrid. When the geogrid is laid, the direction of high strength is arranged perpendicular to the axis of the embankment. Geotechnical The grille is laid horizontally, and is tightly tensioned when laying, and is pulled tightly to avoid wrinkles, twists or potholes. The geogrid is spliced ​​along the longitudinal direction by a lap joint method, and the lap width is not less than 20 cm.

After laying the geogrid, manually lay the upper layer of filler, complete the rolling in time, avoid long-term exposure, and then use mechanical transportation, leveling, rolling, mechanical paving, rolling and pushing from the two sides to the middle, rolling from both sides In the middle, the degree of compaction is maintained to meet the specifications.

Eliminate all construction vehicles and construction machinery to drive or park on the paved geogrid. Check the quality of the geogrid at any time during construction. If it is damaged, puncture, tear, etc., repair or replace it.
