Embodiment Construction

[0009] see figure 1 and figure 2 , the method of the present invention comprises the steps:

[0010] A steel bar 2 with a diameter of 25-32 mm is implanted horizontally or vertically in the underground wall 1 of the old station, and a steel corbel 4 is set at the junction of the roof 3 of the new station and the underground wall 1 of the old station and welded with the implanted steel bar 2, and the corbel 4 A reinforcement mesh sheet 5 with a diameter of 25-50 mm is installed below, and a water-expandable putty water-stop strip 6 and a full-section grouting pipe 7 are installed at the junction of the roof 3 of the new station and the underground wall 1, and then in the said Inject grout into the grouting pipe.

[0011] Said water-swellable putty waterstop strip 6 can adopt commercially available products, such as the product of the Changning brand produced by Shanghai Changning Rubber Factory.

[0012] figure 1 The middle is the case where the roof 3 of the new station i...

Abstract

The invention discloses a waterproofing treatment method for a seam between a novel station and an old station, comprising the following steps: reinforcing steel bars (2) are horizontally or vertically arranged inside an underground wall (1) of the old station; steel corbels (4) are arranged on connecting positions of crest slabs (3) of the novel station and the underground wall (1) of the old station and welded with embedded reinforcing steel bars (2); reinforcing mat plates (5) are arranged under the corbels (4); water swelling putty water-stop strips (6) and full-face injectable slip-casting pipes (7) are arranged on the connecting positions of the crest slabs (3) of the novel station and the underground wall (1), and the last step is to inject cement slurry in the slip-casting pipes. The invention can fully solve the structural water leakage problem due to differential settlement when the novel structure is connected with the old structure. After the waterproof node processing technology of the invention is adopted, water resistance in the seam of the novel structure and the old structure is effectively guaranteed and simultaneously settlement between the two structures is guaranteed.

Description

technical field [0001] The invention relates to a waterproof treatment method for buildings, in particular to a waterproof treatment method for joints between new stations and old stations. Background technique [0002] At present, there are many ways to deal with waterproof joints of buildings, such as stations, but the effective waterproof joint treatment technology between new and old stations is relatively immature, and there is a lack of effective technology in this regard. Contents of the invention [0003] The technical problem to be solved by the present invention is to disclose a waterproof treatment method for the seam between the new station and the old station, so as to meet the needs of related fields. [0004] Method of the present invention comprises the steps: [0005] Horizontally or vertically implant steel bars in the underground wall of the old station. Set steel corbels at the junction of the roof of the new station and the ground wall of the old stat...
