り、極めて単純化された工程から構成される。The present invention has the following effects because it has the above configuration and method. (1) Since the casing and the connecting member can be attached and detached using the existing propulsion cylinder, a dedicated cylinder for moving the connecting member in the axial direction is not required, and the piping device of the small-diameter pipe propulsion machine is greatly reduced. Cost can be reduced. (2) Since the attachment and detachment of the casing and the connecting member can be performed extremely easily using the existing propulsion cylinder, the construction period of the buried pipe propulsion construction can be shortened and the construction cost can be reduced. (3) Since the guide fixed to the pressing plate member and guiding the casing to the pressing plate member is provided, the positioning of the casing with respect to the connecting member connected to the pressing plate member is automatically and reliably performed, and the connection with the casing is established. The efficiency of the connection work with the member can be improved. (4) After connecting the connecting member to the casing and removing the temporary fixing member, the propulsion cylinder is contracted to retract the pressing plate member, and until the pressing plate member and the connecting member are connected by the temporary fixing member. Except that the temporary fixing member is removed only between the casings, the casing and the connecting member are connected by the temporary fixing member, and are constituted by an extremely simplified process.

ができる。(5) In the method of attaching and detaching the connection member to and from the casing of the piping device of the small-diameter pipe propulsion device, the connection member is connected to the casing, the temporary fixing member is removed, and then the propulsion cylinder is contracted. The casing and the connecting member are connected by a temporary fixing member, except that the temporary fixing member is removed only until the pressing plate member is retracted and the pressing plate member and the connecting member are connected by the temporary fixing member,
Since the steps are extremely simplified, the efficiency of the connection operation between the casing and the connection member can be greatly improved. (6) In the method of removing the connection member from the casing, the propulsion cylinder is contracted to retract the pressing plate member,
When the contraction of the propulsion cylinder is stopped when the engagement portion of the connection member and the engagement portion fixed to the push plate member are aligned, and the push plate member and the connection member are connected by the temporary fixing member, During the contraction of the propulsion cylinder until the joints are aligned, the stability of the connecting member is improved because the connecting member is connected to the casing. In addition, by temporarily retracting the push plate member by contracting the propulsion cylinder after releasing the connection between the connection member and the casing, a temporary fixing member is provided between the engagement portion of the connection member and the engagement portion fixed to the push plate member. Is automatically engaged,
The connection work efficiency between the connection member and the casing can be improved.
