Construction method of underwater placing using treme tube and underwater injection device used in the method of construction

摘要

Problem to be solved: to realize a construction method and a water injection device of a structure capable of reducing the contact between the input material and water in the torme pipe.According to an underwater input device (1) according to one embodiment of the present invention, after the torme tube (10) is placed in water and the tube is filled with water, the gas is pumped from the gas pressure delivery part (30) into the treme tube (10) to drain water in the pipe, and then the cavity (10a) is discharged The material is put into the tube.Diagram
