DETERIORATED PIPE REPLACEMENT METHOD AND OPERATION MACHINE

摘要

PURPOSE:To replace a pipe easily by linking a conduit to a shaft to reach, and after that, connecting an operation machine to the head of a propeller machine, and drawing the operation machine with a front jack while pushing it with the propeller machine. CONSTITUTION:A propeller machine A is set in a starting shaft X, a metal crown is installed to the head of a conduit B with the inner diameter a little larger than the outer diameter of an existing pipe C at the head of the machine A, and the conduit B is propelled to a shaft Y to reach while rotating the conduit B. Then, an operation machine is installed to the propeller machine A, it is connected to a Gewinde steel rod F linking from a front jack E, a new Hume concrete pipe D is connected to the rear side of the operation machine 1, and the conduit B and the rear end of the existing pipe C are connected at the front side. Then, by operating the front jack E and the propeller machine A at a time, the conduit B and the existing pipe C are pushed out, and the pipe D is pulled and set. In such a way, the replacement can be carried out easily.
