Detailed Description
As shown in figures 1-2, the underground structure induction seam of the invention is arranged on a top plate 1 of a basement structure, and comprises the top plate 1 of the basement structure, an induction seam 2 is formed at the position where the structure top plate 1 needs to be provided with the seam in a breaking mode and serves as an easy-cracking part, a sealing structure 3 for sealing the lower opening of the induction seam 2 is fixedly arranged on the bottom surface of the structure top plate 1, a prefabricated cover plate 4 is arranged on the upper opening cover of the induction seam 2, a layer of JS waterproof paint 5 with the thickness of 2.0mm is coated in the induction seam 2, a drainage pipeline 6 connected with the outside is arranged at the bottom of the induction seam 2, the drainage pipeline 6 is led out from the lower part of the induction seam 2 and led into a sump of the basement, and the drainage pipeline 6 is arranged at intervals of 20m along the length direction of the induction seam 2.
The sealing structure 3 is of a reinforced concrete structure, is integrally U-shaped and is cast and molded together with the structural top plate 1. The inner wall of the upper part of the induction seam 2 is provided with a convex block 7, the convex block 7 is of a reinforced concrete structure and is cast and molded together with the structural top plate 1, the prefabricated cover plate 4 is arranged on the convex block 7 to seal the upper opening of the induction seam 2, and the gap between the prefabricated cover plate 4 and the structural top plate 1 is filled with an anticorrosive waterproof sealant 8 for sealing, so that the waterproof performance is improved.
