Embodiment Construction
[0031] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0032] Such as Figure 1-9 As shown, a post-casting belt advanced water-stop construction method for abundant groundwater level, which is used for the construction of the post-casting belt of the foundation floor, the construction of the post-casting belt of the basement external wall, the construction of the construction joint of the basement external wall guide wall, and no waterproofing Post-cast beam slab construction is required.
[0033] 1. The construction of the post-pouring belt of the foundation floor includes the following steps:
[0034] (1) After the formwork of the post-cast belt of the foundation floor is supported, a 3*350 steel plate water stop 1 is added to the cast belt;
[0035] (2) The post-pouring belt construction of the basement raft slab adopts the advanced water-s...

The invention discloses a post-cast strip advanced water stop construction method for increasing the underground water level. The method can be used for foundation base plate post-cast strip construction, basement exterior wall post-cast strip construction, basement exterior wall guide wall construction joint construction and post-cast strip beam plate construction with no waterproof requirement. According to the post-cast strip advanced water stop construction method for increasing the underground water level, the whole project time limit can be greatly shortened, the phenomena that due to the fact that underground water is leaked into a basement, potential quality and safety hazards, slow work of labor and non-overlap joint of working procedures are caused, and economic benefit loss and social poor influences are caused are avoided.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a construction method for post-pouring and advanced water-stopping for abundant groundwater levels. Background technique [0002] Due to the high groundwater level in the project construction area, especially in the wet season, the water level is only about 2m above the ground surface, which is -2.8m relative to the building elevation, while the design raft top elevation of this project is -5.12m. In this way, the water in the foundation pit is likely to leak into the interior of the basement from the gaps in the steel mesh sheets at the vertical or horizontal post-pouring belts of the basement, causing certain quality and safety hazards. In general, the construction of the post-casting belt must wait until the two sides of the post-casting belt have settled evenly for a certain period of time before the sealing treatment can be carried out, which will affect the...
