Abstract
Description
Technical Field

[0002] In the construction of new pipe networks, it is very important to use closed water test and CCTV detection to detect leakage at the pipe joints, which is a very important task to inspect the construction quality. However, in the actual construction of the jacking pipe, dewatering wells are generally arranged around the working well and the jacking pipe line to lower the groundwater level. A section needs to be pushed in the jacking pipe and CCTV detection is performed. This method has the following disadvantages: First, during the detection process, it cannot truly reflect the water-stopping effect of the rubber ring at the pipe joint under the state of pressurized water after the dewatering well is removed after the construction is completed; second, multiple CCTV detections are required, which has a long cycle and high cost. If a closed water test is used to detect leakage, this method has the following disadvantages: first, it is necessary to carry out a closed water test after a one-time jacking forming, and it is impossible to grasp the construction quality of each section of the jacking pipe connection in time, which is not conducive to the control of the construction quality process; second, the length of the jacking pipe after the jacking forming is long, even more than 1km, and the pipe section is filled with water, which requires a lot of water and electricity, takes a long time, and does not conform to the concept of green, low-carbon and environmentally friendly construction; third, before carrying out the closed water test, all reserved holes need to be blocked in advance, which increases the cost.
[0003] Therefore, in order to solve such problems, we proposed a water-stopping device for detecting the rubber ring of the pipeline in a simulated underground pressurized water environment. Utility Model Content
