容易になる。Function> The bottom block includes a combination of an outer cylinder member and an invert holding member disposed within the outer cylinder member, and the outer cylinder member has the following features:
It has a pipe joint part for external piping connection, and the invert holding member has an invert part on one side, so when assembling the manhole, the invert holding member having the invert part is attached to the outer cylinder having the pipe joint part. It can be separated from the component and carried out in a separate process. When connecting external piping, insert the external piping into the pipe joint before placing the invert holding member inside the outer cylinder member, introduce its end into the empty internal space of the outer cylinder member, and then It can be connected by extruding it in the direction of other external piping. Therefore, external piping connection work becomes easier.

部が管継手部及び外部配管に連通ずるようになる。After the external piping connection work is completed, it is inserted into the outer cylinder member, which is an invert holding member. The invert holding member has an invert portion on one surface, and is disposed within the outer cylinder member such that the invert portion is located in a position corresponding to the pipe joint portion. Therefore, the invert holding member
The section comes into communication with the pipe joint section and external piping.

設冒位置を変更する必要もなくなる。If there is an in-plane rotational misalignment between the invert part provided on the invert holding member and the pipe joint part or external piping of the outer cylinder member, the invert holding member may be moved inside or outside the outer cylinder member. You can align the plane by rotating the plane. Therefore, even if a rotational position shift occurs, there is no need to redo the piping work on the external piping, and there is no need to change the installation position of the manhole.

できる。(C) Once the manhole has been installed, if it is found that the number of pipe joints in the manhole and the number of external pipes to be connected are different, it is sufficient to replace only the Invar 1 holding member. Change work is easy, and it is economical as it can reduce the cost at the time of change (one folded manhole can be replaced at the same time).
