Geotechnical dewatering bag laying is to be laid by artificial tide when the beach is exposed at low tide level. Before laying, block stones, sundries and other objects that impede quality should be removed before laying.

Before laying the HDPE geomembrane, please supervise the engineer to fully confirm the site conditions to ensure that the foundation surface is flat, free of unevenness, and no sharp particles and hard debris that may damage the HDPE geomembrane. The materials (various performance indicators, whether there are bubbles, holes, wrinkles, damage, etc. on the surface) are sent to a third-party organization for strict inspection and qualified, and then laid after confirmation.

Geotechnical pipe bag or a large-scale pipe bag and inclusion made of high-strength geotextile, its diameter can be changed according to needs, and the length has exceeded tens of meters. Geotechnical pipe bags were originally used in dike engineering. At present, through the efforts of the majority of technical workers, they have been applied to environmental protection, agriculture and other fields. With the deepening of people's research, their application fields will become more and more extensive.

Construction method and technology of geocell: 1. Working face: Some existing slopes have reached the requirements, slope restoration is under way, and working face will be provided one after another. The smoothness of slope is directly related to the success or failure of geosynclast grass protection. It tends to produce stress concentration and cracking of the solder joints in the lattice chamber.

Geotextile tube bag is a new type of sludge dewatering consolidation technology, in the construction site will mud pumping by pumping system has higher strength and filterability of tube bag, bag of localized wall geotextiles and drainage, by gravity and bag wall tension, to make the moisture in the mud discharge quickly, and the solid particles in the mud are retained in the bag.
