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] Such as 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 i...

Abstract

The invention discloses a pipe gallery joint waterproofness test method, which is used for carrying out a waterproofness test on a jack type pipe gallery. Water is injected into an axial joint in a labyrinth type butt joint by utilizing a water injection pipe. Compared with a method for injecting the water from the outer side to the inner side, the method for injecting the water from the middle and extending the water to two outer ends has the advantage that equivalently two groups of waterproofness tests are carried out at the same time, so that the test efficiency is greatly improved, the test time is shortened, and the problem that the test effect is influenced because the water injection time is not accurate, the water pressure cannot be increased and the like due to transverse diffusion of water flow during water injection is also avoided. The pipe gallery joint waterproofness test method has the advantages of being convenient, rapid and efficient in operation, accurate in test result 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...
