A through-hole 3 having an inner diameter through which the branch pipe 2 (FIG. 2 and below) can be inserted is formed in the peripheral wall of the main pipe 1 made of RP, and has a center hole 4A having an inner diameter d smaller than the outer diameter D of the branch pipe 2. The packing member 4 is adhesively fixed to the outer periphery of the main pipe 1 so as to be concentric with the through hole 3, and then, as shown in FIG. And joining the end portion 2A of the branch pipe 2 to the inner surface 1A of the main pipe 1 with a watertight member 5 from the inside of the main pipe 1.

外周との間が確実に接着される。In the above embodiment, the packing member 4 is formed of an elastic sheet, and an elastic member made of a material that can be bonded to the main pipe 1 and the branch pipe 2, for example, a sheet made of synthetic rubber or urethane resin is used. Is done. Further, in the above embodiment, when the branch pipe 2 is inserted through the center hole 4A of the donut-shaped packing member 4, it is desirable to apply an adhesive in advance to the contact surfaces of each other. By applying the adhesive, the adhesive functions as a lubricant at an uncured stage, facilitating insertion, and at the time of curing, the packing 4 is used.

となり防水が確実に図られる。In the present invention, the donut-shaped packing 4 is adhered to the outer periphery of the main pipe 1 because the packing 4 is an elastic sheet. It can be glued out of the tube. In addition, since the inner diameter d of the center hole 4A is smaller than the outer diameter of the branch pipe 2, when the branch pipe 2 is inserted, the donut-shaped packing member 4 is effectively sealed around the pipe, and becomes tight against external groundwater pressure. Waterproofing is ensured.
