Vacuum-suction prefabricated integral drainage board fittings

The fittings are made of integral drainage boards with a prefabricated length and two ports through fusion and sealing and penetrate the perforated plastic pipe. The fittings are fixed to the holes at the connection with the hot-melt adhesive through fusion bonding, with the following characteristics:

(1) The connections are glued and sealed firmly to prevent the inhalation of silt.

(2) The fittings can be used for direct vacuum-suction water drainage and consolidation of the 5m ~ 7m shallow layer of supersoft silt, float sludge, and mud.

(3) The prefabricated integral drainage board fittings can replace the pipe connection process on the drainage board construction site, improving the efficiency of construction.
