PURPOSE:To easily perform a water pressure test even with respect to inclined piping, by allowing a truck to run by a winch in piping and mounting an apparatus such as a test band, which performs the water pressure test of the inner surface of a pipe joint part between the receiving port thereof and the insert port thereof, to said truck. CONSTITUTION:Piping 1 is arranged along the inclined ground and a receiving port 3 an insert port 4 are provided to a pipe joint part 2. A truck 6 is arranged in this piping 1 and a test band 9 is mounted to the truck 6. The test band 9 is formed into a ring shape along the inner surface of the piping 1 and one leading end thereof is closely contacted with the receiving port 3 through a rubber gasket 11 while the other end thereof is closely contacted with the insert port 4 in the same way and water pressure is applied to perform a close contact test. Water is sent to the test band 9 from the water tank 24 mounted to the truck 6. A wire 39 is attached to the bracket 38 of the truck 6 which is, in turn, allowed to run and stop by a winch 42. Because the truck is freely run by the winch 42, a water pressure test can be easily performed and water feed piping from the outside can be dispensed with because the water tank is mounted thereon. |
