In addition, affected by the cable layout, the technical difficulty of hole blocking is large, and different degrees of water seepage and leakage also occur in some projects in the later stage. Moreover, after the cable is blocked, it is not convenient for maintenance, and the replacement cost is relatively high. Content of the Utility Model

[0027] The present utility model will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0028] As Figures 1-5 shown, a waterproof structure applicable to an underground structural wall passing through a cable pipeline includes an underground structural wall 1, and also includes an inner side sealing plate 2, an outer side sealing plate 3, and a pipeline casing 4. An inner side sealing plate 2 is provided on the inner side of the underground structural wall 1 at the opening position. An exhaust pipe 21 is provided at the top of the first end of the inner side sealing plate 2, and a grouting pipe 22 is provided at the bottom of the second end of the inner side sealing plate 2;

[0029] An outer side sealing plate 3 is provided on the outer side of the underground structural wall 1 at the opening position. A plurality of pipeline casings 4 are welded on the outer side sealing plate 3, and the pipeline casings 4 are arranged according to the number of cables; A plurality of pipeline casings 4 are penetrated through the inner side sealing plate 2 and the outer side sealing plate 3, and the pipeline casings 4 are respectively welded to the inner side sealing plate 2 and the outer side sealing plate 3; The two sides of the inner side sealing plate 2 and the outer side sealing plate 3 are respectively fixed to the underground structural wall 1; Grouting 5 is provided in the space between the inner side sealing plate 2, the outer side sealing plate 3, and the plurality of pipeline casings 4. The grouting material adopts a non-shrinking and self-compacting material, and the strength of the grouting material is preferably one grade higher than the strength of the wall concrete.

[0030] The first end and the second end of the inner side sealing plate 2 are fixed to the underground structural wall 1 by cement nails.

[0031] The gap at the connection between the inner side sealing plate 2 and the underground structural wall 1 is sealed by a sealant 6 to ensure the density of the gap around the wall.

[0032] The first end and the second end of the outer side sealing plate 3 are fixed to the underground structural wall 1 by cement nails.

[0033] The gap at the connection between the outer side sealing plate 3 and the underground structural wall 1 is sealed by a sealant 6 to ensure the density of the gap around the wall.

[0034] After the outer side sealing plate 3 is fixed, the inner side sealing plate 2 is installed. The inner side sealing plate 2 is provided with an opening at the same position as the outer side sealing plate 3, and the pipeline casing 4 is penetrated and welded. The wall at the contact part with the sealing plate needs to be appropriately polished to ensure the flatness of the fit between the sealing plate and the wall.

[0035] The sizes of the inner and outer side sealing plates are 25 cm outward expansion around the opening position of the underground structural wall 1, and the thicknesses of the two side sealing plates need to be determined according to the opening size.

[0036] The diameter of the exhaust pipe 21 is 50 mm, and the diameter of the grouting pipe 22 is 50 mm.

[0037] The part of the pipeline casing 4 located outside the underground structural wall 1 bends upward, and the top elevation is attached to the top of the external pipe trench, and the distance from the top needs to meet the cable laying space, and the bending radius meets the installation requirements for cable laying.

[0039] Expansion sealant is provided in the gap between the two ends of the pipeline casing 4 and the cable to prevent accumulated water from flowing into the underground structural wall 1.

[0040] Specifically, the waterproof structure applicable to the underground structural wall crossing the cable pipeline is implemented in the following manner:

[0041] First, install the outer sealing plate 3, then install the inner sealing plate 2. After the inner and outer sealing plates are fixed by cement nails, set the sealant 6 at the gaps around the underground structural wall 1 of the inner and outer sealing plates, and then grout the space formed by the inner and outer sealing plates to fill it densely. The grout enters from the grouting pipe 22 and flows out from the exhaust pipe 21. The exhaust pipe 21 also serves as a return grouting pipe. After the cable laying is completed, use expansion sealant to block the two ends of each pipeline casing.

[0042] The above specific implementation manners are used to explain the present utility model, which is only the preferred embodiment of the present utility model, rather than a limitation to the present utility model.
