Problems solved by technology

[0003] However, the traditional test method needs to make a whole pipe joint for waterproof test. The preparation in the early stage is time-consuming and labor-intensive, and the test steps are cumbersome, and it cannot simulate different stress conditions and deformation conditions of the pipe gallery. The scope of application is not wide

Embodiment

[0030] like figure 1 As shown, in the waterproof test method for pipe gallery joints in this embodiment, the pipe gallery is a plug-in type pipe gallery, and its butt joint 1 is a labyrinth joint, including a first radial joint 11, an axial joint 12 and a second radial joint. Two radial joints 13, the butt joint 1 also includes several sealing layers, the pipe gallery also includes a water injection pipe 14, the end of the water injection pipe 14 communicates with the axial joint 12, and several sealing layers are in the butt joint 1 is arranged symmetrically with respect to the access point of the water injection pipe 14, and water is injected into the axial joint 12 through the water injection pipe 14 during the test. Compared with the method of injecting water from the outside to the inside, this method of injecting water from the middle and extending to the two outer ends is equivalent to conducting two sets of waterproof tests at the same time, which not only greatly impr...

Abstract

The invention discloses a waterproof test method for pipe gallery joints, which is used for waterproof testing of socket-type pipe galleries. Compared with the method of injecting water from the outside to the inside, the method of extending the outer end is equivalent to carrying out two sets of waterproof tests at the same time. Inaccurate water injection time and inability to increase the water pressure and other problems that affect the test results. The waterproof test method for pipe gallery joints of the present invention has the advantages of convenient operation, fast and efficient, accurate test results, and the like.

Description

technical field [0001] The invention relates to a sealing test method, in particular to a waterproof test method for pipe gallery joints. Background technique [0002] Comprehensive pipe gallery refers to the comprehensive corridor of underground urban pipelines, that is, to build a tunnel underground space underground in the city, and integrate various pipelines such as electricity, communication, water supply and drainage, and natural gas according to certain spatial layout requirements, and set up special maintenance facilities at the same time. Channels, hoisting ports and monitoring systems, etc., form an integrated underground pipeline corridor. The existing comprehensive pipe gallery needs to bear the uneven settlement of the foundation soil or the action of seismic waves, etc., and once the water leaks due to this situation, its internal pipeline is extremely easy to be damaged, so it is necessary to waterproof the joints of the pipe sections before use Test, throug...
