Problems solved by technology

Since people cannot enter the interior of the pipeline to check the location of the defect point, epoxy resin is generally used as a curing glue for repair materials. However, the curing time of epoxy resin is long, which leads to a longer operation period, so people start to use UV curing glue to fix the defects. Instead of epoxy resin for repair, but UV curing glue needs ultraviolet light to cure

Embodiment 1

[0051] See figure 1 with figure 2 , A pipeline repair airbag, comprising two positioning frames 2 and an airbag body 1 connected to the two positioning frames 2. The airbag body 1 is made of a resin having translucency. The airbag body 1 and the two positioning frames 2 are enclosed to form an airbag cavity 11 in which the airbag body 1 is inflated by inflation. The positioning frame 2 is also connected with an ultraviolet lamp assembly 3 arranged inside the airbag cavity 11. The ultraviolet lamp assembly 3 includes an ultraviolet lamp body 32 connected to the positioning frame 2 through a lamp holder 31, and a protective cover 33 covering the outer periphery of the ultraviolet lamp body 32. The protective cover 33 is a wire mesh frame enclosed by iron wires, so that the ultraviolet Light can pass through the protective cover 33. The positioning frame 2 is also provided with a connecting tube 4 communicating with the airbag cavity 11, and the connecting tube 4 includes a ch...

Embodiment 2

[0058] See Figure 9 to Figure 13 , A pipeline repair process using the first embodiment includes the following steps:

[0059] Pipeline cleaning, see Picture 9

[0060] Step 1.1, determine the section of underground pipeline 91 that needs to be repaired, and set up road barriers 61 and warning signs 62 in the circumferential direction at the two drainage wells 6 that are located at both ends of the section of underground pipeline 91 and communicate with the section of underground pipeline 91. (For ease of presentation, The two drainage wells 6 are respectively named the first drainage well 63 and the second drainage well 64);

[0061] Step1.2, manually enter the first drainage well 63 and the second drainage well 64, and separate the underground pipe 91 in the section that needs to be repaired and the underground pipe 9 in the section that does not need to be repaired by a sealing plate 65 with a water hole;

[0062] Step1.3, park the dredging vehicle 71 near the first drainage wel...

Abstract

The invention discloses a pipe repair airbag and a pipe repair process adopting the pipe repair airbag, and solves the problem of capability of curing UV curing glue by ultraviolet irradiation. The pipe repair airbag comprises a cylindrical airbag body, and positioning frames connected to the two end parts of the airbag body; the airbag body is made of a rubber film with light transmittance; airbag cavities for inflation are formed between the positioning frames and the airbag body; the positioning frames are connected with ultraviolet lamp modules inserted in the airbag cavities; the ultraviolet lamp modules comprise lamp bases fixedly arranged on the positioning frames, and ultraviolet lamp bodies connected to the lamp bases; the the positioning frames are connected with protective covers covering the peripheries of the ultraviolet lamp bodies. The pipe repair airbag can cure the UV curing glue, shortens the repair time, saves the construction period and the labor cost, and is excellent in repair effect.

Description

Technical field [0001] The invention relates to pipeline repair, in particular to a pipeline repair airbag and a pipeline repair process using the pipeline repair airbag. Background technique [0002] In the past, when municipal drainage pipelines, agricultural water, industrial water and tap water pipelines, gas pipelines and other underground pipelines and inspection wells were damaged, in order to repair the damaged section, it was usually necessary to excavate the ground of the damaged section of the pipeline. , To replace the damaged section of the pipeline. Obviously, the above-mentioned method of overall repairing damaged underground pipelines and inspection wells after excavation is labor-intensive, time-consuming, low-efficiency and high-cost. [0003] In recent years, a non-excavation integral repair method has been developed and used in practical applications to repair the above-mentioned damaged underground pipelines and inspection well sections as a whole. Such as Fi...
