Abstract:

PROBLEM TO BE SOLVED: To provide a novel sheath pipe for the foundation penetration, which can prevent deformation when casting concrete.SOLUTION: A sheath pipe 10 for the foundation penetration comprises: a sheath pipe body 30 having an upper opening 36a and a lateral opening; and a curing lid 50 attached to the upper opening of the sheath pipe body. The curing lid 50 has a fitting portion to be fitted in the upper opening 36a and can appropriately prevent deformation of the sheath pipe body 30 due to a raw concrete pressure during concrete casting since the curing lid supports a portion of the upper opening 36a of the sheath pipe body 30 from an inside. Further, the sheath pipe body 30 can prevent accidental disengagement of the curing lid 50 from the upper opening 36a since a retaining projection of the curing lid 50 projecting from an inner edge portion of the upper opening 36a is provided between the sheath pipe body 30 and the curing lid 50.SELECTED DRAWING: Figure 3
