Abstract

PURPOSE: To make sure of welding by forming an impermeable membrane having an axial unit length in the shape of a cylinder to lap the circumferential end and, at the same time, connecting the axial rear end to the existing impermeable membrane axial end without making laps on their circumferential ends overlap each other. CONSTITUTION: The circumferential ends are lapped to make an impermeable membrane 6' having an axial unit length as a lap section Y' so as to form the impermeable membrane in the shape of a cylinder along the inside of a shield frame. Then, the axial rear end is made to overlap with the axial front end from the inside to form a lap X section to connect so as to slip by a required interval from lap Y sections on the circumferential ends of the exisiting impermeable membrane 6. Successively the coating and connection of the impermeable membranes are made to arrange the laps in the circumferential ends of the impermeable membranes in the shape of zigzag. By the constitution, breaking or the like in the case of connection can be decreased.
