Problems solved by technology
[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that during the construction of the basement, when the roof and the inner support are at the same or similar elevation, the inner support will affect the construction of the side wall. If the inner support is removed before the side wall construction The support will cause a large displacement of the foundation pit and the defects that the safety cannot be guaranteed, thus providing a safe and reliable basement construction method

The invention provides a basement construction method, and belongs to the technical field of basement construction. The basement construction method comprises the following steps of mounting an innersupport on a supporting structure; arranging a foundation pit; before removing the inner support, constructing a basement raft in the foundation pit and a first-stage external wall, wherein the first-stage external wall is lower than the inner support, and embedding a water-stop steel plate at the top end of the first-stage external wall, wherein a part of the water-stop steel plate upwards extends out of the first-stage external wall; and filling parts between the raft and the supporting structure and between the first-stage external wall and the supporting structure with supporting packing;removing the inner support; and constructing a second-stage external wall at the top end of the first-stage external wall continuously until enabling the second-stage external wall to reach a top plate. The basement construction method can not only avoid deviation during the process of constructing the foundation pit, but also do not influence the subsequent construction of the top plate.
Description
technical field [0001] The invention relates to the technical field of basement construction, in particular to a basement construction method. Background technique [0002] As the basic part of the building, the basement has a variety of construction techniques and methods because of its importance. In order to ensure the safety and stability of the foundation pit during the construction of the basement, the foundation pit is usually stabilized in the form of a water-stop curtain + supporting piles. If the surrounding conditions of the foundation pit are complex and there are many buildings, etc., it is necessary to add internal supports to the support to ensure that the deformation of the foundation pit will not be too large and cause damage to the surrounding buildings. [0003] For the foundation pit support form with only one inner support, when constructing the basement structure, it is usually encountered that the elevation of the basement roof and the inner support i...
