How to install geotextile membranes?

There are two laying methods for geotextiles.

Choose an appropriate method between manual rolling and mechanical assistance for laying. Regardless of the method, ensure that the geotextile surface is laid flat and allows for some deformation allowance. The mechanical assistance method involves placing the geotextile roll on the arm架 of the laying boat's traction mechanism and securing it firmly. The laying boat then slowly enters the laying area, precisely positioning the location to be laid using the GPS global positioning system, and proceeds with the laying.

Geotextile membrane for landfill application involves several steps. Firstly, the subgrade is leveled using sand. Then, the geotextile membrane is laid. It's important to note that the membrane should not be too tight; the buried portion should be wavy. Subsequently, sand is used to fill the geotextile as a transition layer, typically around 10 centimeters thick. Finally, a protective layer is laid on top using concrete.

Resurface Coverage

Geotextile membranes should be covered with backfill immediately after installation. The side walls and top plates within a 2-meter range are backfilled with loam soil, achieving a compaction level of over 95%. The soil within a 0.5-meter range of the side walls is compacted manually. After the soil thickness on the top plate reaches 0.3 meters, light roller compaction is applied. As shown in the following figure.
