The first sealing ring 32 is fixedly sleeved on the fixing plate 31, and the first sealing ring 32 is tightly pressed against the inner wall of the penetration hole 11. In the embodiment of the present application, two first sealing rings 32 are provided, so as to form a closed space between the fixing plate 31 and the wall 1; and indirectly improve the sealing between the sleeve 2 and the inner wall of the penetration hole 11.

[0034] See also Figure 1 and Figure 2 The fixing pipe 33 is fixed on the fixing plate 31, and the fixing pipe 33 is connected to the fixing groove 311. After the sleeve 2 is placed in the penetration hole 11, concrete slurry is injected into the fixing groove 311 through the fixing pipe 33; after the concrete slurry solidifies, the sleeve 2 can be fixed, so that the sleeve 2 is not easily removed from the penetration hole 11. The first rubber plug 34 is set in the end of the fixing pipe 33 away from the fixing plate 31. After the concrete slurry is injected, the first rubber plug 34 can be inserted into the fixing pipe 33 to prevent rainwater or other water from entering the fixing pipe 33.

[0035] See also Figure 1 and Figure 2 The connecting component includes: a sealing portion 4, a crushing portion 6 and a connecting portion 5. In the embodiment of the present application, two connecting components are provided, and the two connecting components are symmetrically arranged with the fixing plate 31 as the central axis.

In the process of filling the sealant into the filling tube 42, the crushing part 6 crushes the bag 52 to allow the sealant in the bag 52 to flow into the filling groove 511 through the connecting hole 532; after the sealant in the filling groove 511 solidifies, the connection between the sleeve 2 and the cable 12 can be completed, and the sealing between the connecting plate 51 and the cable 12 can be guaranteed.

[0040] See also Figure 1 and Figure 2 Furthermore, the connecting portion 5 also includes: a rubber block 54, which is arranged in the movable groove 22, and the rubber block 54 is fixedly connected to the movable block 53, and the rubber block 54 is used to improve the sealing between the connecting plate 51 and the movable groove 22; in the embodiment of the present application, there are two rubber blocks 54 in a single connecting portion 5, and the two rubber blocks 54 are symmetrically arranged with the movable block 53 as the center axis.

[0041] See also Figure 1 and Figure 2Furthermore, the connecting part 5 also includes: a water-absorbing sponge 55, which is arranged in the connecting groove 21, and the water-absorbing sponge 55 is sleeved on the cable 12. If rainwater seeps into between the sleeve 2 and the cable 12, the water-absorbing sponge 55 can quickly absorb the rainwater to prevent the rainwater from soaking the cable 12 for a long time, thereby improving safety.

[0042] See also Figure 1 and Figure 2 Specifically, an annular water-falling cavity 23 is provided on the sleeve 2, and a plurality of water inlet holes 24 are provided between the water-falling cavity 23 and the connecting groove 21; a water collecting trough 25 is provided on the inner bottom wall of the water-falling cavity 23. If the cable 12 is pulled or vibrated, and the movable block 53 is close to the water-absorbing sponge 55, the water-absorbing sponge 55 will be squeezed to squeeze the rainwater on the water-absorbing sponge 55 into the water-falling cavity 23 through the water inlet holes 24, and then automatically fall into the water collecting trough 25, so that the water-absorbing sponge 55 can absorb rainwater for a long time; at the same time, it can buffer the moving force.

[0043] See also Figure 2 and Figure 3 Furthermore, a drop hole 26 is provided on the bottom wall of the water collecting tank 25, and the drop hole 26 is in a truncated cone shape; a water outlet hole 27 is provided through the bottom wall of the drop hole 26. A blocking assembly 7 is provided in the drop hole 26, and the blocking assembly 7 includes: a mesh plate 71, a blocking block 72 and a spring 73, the mesh plate 71 is fixedly provided in the drop hole 26; the blocking block 72 is provided in the drop hole 26, the blocking block 72 is located below the mesh plate 71, and the blocking block 72 can move up and down in the vertical direction.

[0044] See also Figure 2 and Figure 3 , spring 73 is fixed between mesh plate 71 and blocking block 72, and spring 73 is used to reset blocking block 72; when the rainwater in sump 25 reaches a certain weight, blocking block 72 will move downward, thereby opening drop hole 26, so that rainwater in sump 25 can be discharged from outlet hole 27; if the weight is not enough, spring 73 can automatically reset blocking block 72, so that blocking block 72 continues to block drop hole 26, so that external rainwater is not easy to enter.

[0045] See also Figure 2The crushing part 6 includes: a pressing plate 61 and a crushing needle 62. The inner top wall of the movable groove 22 is penetrated with a pressing hole 28, and the pressing plate 61 is arranged in the pressing hole 28. One end of the crushing needle 62 is arranged in the pressing hole 28 and abuts against the pressing plate 61, and the other end penetrates into the bladder 52. During the process of filling the sealant, the sealant slurry will enter the pressing hole 28 to press the pressing plate 61 downward until the crushing needle 62 punctures the bottom of the bladder 52, so that the sealant slurry in the bladder 52 can flow into the filling groove 511 (and the top of the crushing needle 62 no longer remains in the pressing hole 28).

[0046] See also Figure 2 Furthermore, the side wall of the rupture needle 62 is wavy along its length. With such a configuration, after the rupture needle 62 pierces the bag 52, it is not easy for the puncture hole to be blocked by the rupture needle 62, thereby ensuring that the sealant can flow into the filling groove 511.

[0047] The working principle of a cable wall installation construction method of the present application is as follows: after the sleeve 2 is placed in the penetration hole 11, concrete slurry is injected into the fixing groove 311 using the fixing pipe 33; after the concrete slurry solidifies, the sleeve 2 can be fixed, so that the sleeve 2 is not easily removed from the penetration hole 11.
