A third invention of the present application is a pipe connection method for connecting a new pipe body to a pipe body in a mine, and a new pipe body is obtained by the pipe transport device according to the first or second invention. It is transported to the vicinity of the pipe in the mine, and the new pipe is carried out while performing alignment with the roller conveyor as a fulcrum, and connected to the pipe in the mine.

According to the present invention, the following effects can be obtained.
(1) Pipe transportation and connection can be performed with a simple device.
By providing a roller conveyor on the upper surface of the mounting portion, the new pipe can be moved on the mounting portion, and positioning and connection of the new pipe with respect to the existing pipe can be performed efficiently.
There is no need to use a complicated and expensive device like a conventional cart-type transport cart, and there is no need to put the transport cart inside an existing pipe.
(2) Excellent flexibility in field conditions.
Since there is no need to put the transport cart on the existing pipe, the size of the transport cart is not limited by the size of the existing pipe, and the flexibility of adapting to the bottom plate height in the mine and the laying height of the pipe body is excellent. .
(3) Transportation work by one worker becomes possible.
By providing the guide portions on both side surfaces of the travel portion and the mounting portion, the pipe transport device travels along the mine, so that a steering operator on the transport cart side becomes unnecessary.
(4) The risk of contact can be reduced.
By providing the guide portion, it is possible to reduce the possibility that an operator or a tubular body contacts the wall surface in the mine.
In particular, the steering operator on the side of the transport truck has a high risk of contact because it is necessary to get inside the existing pipe. However, since the operator can be made unnecessary, the danger can be eliminated.
