Document Type and Number:
Japanese Patent JP3390750
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the sealing performance of a clearance between an insertion hole and a pipe unit while improving seal workability, by simplifying seal of the clearance between the insertion hole and the pipe unit.
SOLUTION: A hand hole H formed into a box shape by vertically providing a sidewall 12 in a bottom wall 10 and formed with a recessed part 15 having an opening port 14 in an upper end of the sidewall 12 is prepared; an insertion hole 13 for inserting a pipe unit K is drilled so as to make its intermediate part external periphery communicate with the recessed part 15 in a surface part 11 of the sidewall 12 of this hand hole H; the pipe unit K is inserted to the insertion hole 13; thereafter, sealing agent M is poured in from the opening port 14 of the recessed part 15; an external periphery of the pipe unit K exposed in the recessed part 15 from the intermediate part of the insertion hole 13 makes the sealing agent M adhere; it is buried in the recessed part 15; and the pipe unit K and the insertion hole 13 are connected to be sealed with the sealing agent M.
