The method for installing the anti-seepage and anti-leakage post-embedded device of the foundation pit support structure comprises the following steps:
and 1, before the construction of the internal structure 2, arranging a drainage hose 3 at the seepage area 11 of the foundation pit support structure 1. Specifically, in the foundation pit excavation stage, along with the excavation process, a drainage hose 3 is arranged in a leakage area, so that the concentrated drainage of leakage water is ensured, and the excavation quality is ensured. Steps 2 to 4 are performed at the stage of constructing the internal structure 2.

Based on the improvement: when the second end of the extension pipe section 42 is penetrated out through the hole, the cup opening structure 7 is propped against the inner side template 21 (shown in fig. 1); after the closure is attached to the butt end of the main pipe section 41, the cup opening structure 7 is filled with plastering mortar so that the plastering mortar covers the closure and is flush with the inside of the inner structure 2. Preferably, after the plugging member is connected to the butt end of the main pipe section 41, it is observed whether there is no water seepage (based on no water seepage observed by naked eyes) for a period of time (preferably 7 days), and if so, the plastering mortar is filled in the cup opening structure 7.
In order to further improve the self-waterproofing performance of the inner structure 2, at least one water stop plate 8 (which may be a ring-shaped steel plate) is fixed (full welded) to the outer periphery of the main pipe section 41, and preferably two water stop plates 8 are provided at intervals along the axial direction of the main pipe section 41. The leakage water cannot flow along the internal structure due to the obstruction of the plurality of water stop plates.
According to the invention, the smoothness and the attractiveness of the surface of the internal structure are ensured by the cooperation of the extension pipe section, the cup opening structure and the trowelling mortar.
The present invention has been described in detail with reference to the embodiments of the drawings, and those skilled in the art can make various modifications to the invention based on the above description.
