How to construct underwater geotextile for deep water soft foundation reclamation
Use special underwater geotextiles built by deck barges to lay the vessel. Before laying the geotextile, all preparations should be made.
Create a GPS differential reference station, input the GPS mobile station of the geotextile laying ship according to the data of the geotextile laying width and the cloth piece, and mark the placement position one by one, and then use it as an important basis for laying the geotextile.
The geotextile is laid by the dock and rolled into a reel inside the ship.
Fill up with gravel in advance when laying geotextile.
Make the anchor fixing the position of the geotextile well, and reasonably stretch and pour the anchor position according to the laying sequence.
The geotextile is rolled up and loosened, and then knotted inside the lifting loop, and then connected to the small anchor on the ship.
The pipelay anchor is positioned to the casting position and waiting for the best casting time after positioning.
It is helpful for smooth laying work during low tide.
