Background
The socket type flexible pipeline is usually used for interval or underground direct burial in the subway construction process, and is generally made of cast iron. During interval construction, the pipeline which leaves a factory is generally cut and processed due to overlarge radian of an interval section, for example, the installation length of the pipeline is generally 4 meters in a range of bending radius smaller than 500. After the above operation, the leakage condition usually occurs in the socket type flexible interface pipeline. The reason was analyzed as follows:
Reason 1, after the pipe spigot is cut, the surface treatment is not smooth, the flexible rubber ring is damaged in the bell and spigot connection process, the tightness is insufficient, and the risk of water leakage is easily formed;
Reason 2, when the flexible rubber ring is installed in an area with a smaller bending radius, the flexible rubber ring is easily stressed unevenly, the flexible rubber ring deforms due to extrusion, and the risk of water leakage occurs;
Reason 3, the ground direct-buried pipeline causes the support of the supporting pipeline to sink due to weak ground foundation pouring, and is easy to cause water leakage of the interface.
When water leakage occurs due to the reasons, the socket type flexible interface pipeline needs to be dismantled for problem treatment. After the socket type flexible interface pipeline is installed, the flexible rubber ring plays a resistance role when the socket is pulled out, so that great workload is caused for dismounting. The existing dismantling method is to pull the two connected pipelines apart by using a chain block, the pipeline is difficult to pull apart due to the flexibility of the chain block and uneven stress when the pipeline is pulled, and the speed of the chain block is too slow, so that the pipeline is time-consuming and labor-consuming to use.
