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...
