Is formed at an appropriate position in the straight pipe 10.
Using an air gun (not shown) or the like, an appropriate amount of the small block 21 of the water blocking wall forming material is driven into the straight pipe 11 by an arbitrary amount from any one of the end screw holes. In this case, as the material for forming the water blocking wall, a swelling material having an appropriate viscosity is used, and the swelling material is formed into an appropriate amount of small lumps as shown in FIG. Is to close.

る。As the water-blocking wall material, an appropriate swelling material is used. For example, a rubber compound such as natural rubber or neoprene rubber and a swellable urethane resin or swellable acrylic resin as a swellable resin are kneaded with an appropriate solvent. However, a material having an appropriate viscosity is used. All of the compositions of such swelling materials are known. Then, a small lump of such a viscous swelling material is sequentially struck little by little toward the inner wall of the straight pipe 10 by an air gun or the like, thereby closing the inside of the straight pipe.

０が完成する。In order to form the water blocking wall by driving the swelling material, the swelling material may be driven into the straight pipe portion of the turnbuckle in advance, or at the site of formwork and wall connection work. It may be performed as needed. Then, the water-blocking wall portion formed of the swelling material is formed by combining the small lumps with each other to form a water-blocking wall (plug) 2 made of the swelling material.

る。In general, at a work site having a retaining wall or the like, water often flows from outside the wall due to the environment of the foundation work, and the water is prevented from entering the new concrete casting formwork. It is important to. For example, water leaking from the retaining wall b in FIG. 1 travels through the screw rod 16 on the wall body b side and enters the straight pipe 10 from the end 14 of the buckle A.

することができる。However, in the present invention, since the water blocking wall 20 made of a swelling material is formed inside the straight pipe 10, when the water leaking into the straight pipe comes into contact with the water blocking wall material, the water blocking wall material itself is formed. Has an expansion rate of 10% to several tens%, and completely blocks the inside of the straight pipe. Therefore, it is possible to completely prevent, for example, water leaking from the mountain retaining wall b from traveling along the buckle A from the screw rod 16 and entering the form a.
