In the technical scheme, the water stop is provided with a nose section, and the nose is arranged towards the direction of the rock stratum; a groove is formed in the top surface of the bottom plate at the parting position, and the nose section is arranged in the groove; the groove is filled with sealant, and a rubber rod is embedded in the nose of the water stop.
In the technical scheme, a flexible coiled material isolation layer is arranged between the cylinder wall and the rock stratum; and a protective cylinder is arranged on the outer wall of the top end of the cylinder wall.
In the technical scheme, the surface of the bottom plate at the parting position is provided with the isolation layer.
The utility model has the advantages that: through cutting off the section of thick bamboo wall and the department that links to each other of bottom plate, make section of thick bamboo wall bottom become the free end, make the bottom plate become the simply supported structural style in edge, effectively reduce the vertical bending moment and the radial bending moment in bottom plate edge of section of thick bamboo wall bottom to attenuate section of thick bamboo wall thickness, attenuate bottom plate edge thickness, save investment, reduce the construction degree of difficulty. The diameter of the top surface of the bottom plate is larger than the outer diameter of the cylinder wall, so that the bottom plate is embedded into the rock stratum to achieve the purpose of effective anti-floating. Through set up flexible coiled material isolation layer between section of thick bamboo wall and stratum, reduce the stratum to the constraint effect of section of thick bamboo wall concrete, reduce section of thick bamboo wall concrete because of the risk that initial stage is dry and temperature deformation produces the fracture. The purpose of effective water stopping is achieved by arranging one metal water stop belt and two water-swelling water stop strips. The purpose of enabling the water stop belt to adapt to deformation is achieved by adopting the metal water stop belt with the nose and embedding the hard rubber rod at the top end of the nose.
