Page 24 571015 Case No. 91115280 V. Description of Invention (19). y In the manhole structure 21 of FIG. 12, the tubular i # is crimped and fixed to the one end 27 a of the cylindrical body 26 and the flexible body 27 by the expansion band 28, and the other end 27 b of the tubular body is tightened with a tie 29. Would like to connect to the 9th side of j ^, the tube-shaped flexible body 27M ^ 26. The concrete was washed inside to form the human body. The soil ^ is the same as the manhole structure 11 and the manhole structure 21, and its person; ^ 丨 Using the end 2 / a of the tubular flexible body 27 of μ u, the projecting bisexual joint = 25 is used in the opposite direction. The direction becomes the corner of the bend. The point of the square tubular body 26 of the sleeve steel pipe 30 is the same as that of FIG. 4. The end portion 27 a is installed in a shape that can be more different from one another. . This structure is beneficial. The heart easily absorbs the displacement of the manhole wall and the pipe, which has more inventive effects. According to the relationship between the person and the sister of the present invention, it is connected by a large cylindrical flexible body such as an earthquake. Different negative lanes: The earth's crust changes. When the manhole wall and the pipe, the tube flexible body can absorb the damage of the negative f2 from the f-position difference from the joint. The position can prevent the manhole wall and the pipe. After connecting the manhole in accordance with the present invention, the manhole can be pulled out with water-stopping structure. After the concrete has been laid by the advancing construction method, the operational core joint is installed in the pipe. When the manhole wall contract is constructed, Can improve the connection 'can simply make the tube and the manhole wall flexible to absorb the water resistance of the part.
