Title:
OPEN FOUNDATION PIT BLOCK CONSTRUCTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/023246
Kind Code:
A1
Abstract:
The present invention relates to the technical field of foundation pit engineering, and relates to an open foundation pit block construction system and method. The problem in which a partition wall enclosure structure cannot be constructed after an existing foundation pit is excavated, and thereby construction cannot be expedited locally, is targeted. In the present invention, for a foundation pit that has been excavated but cannot be constructed by dividing an enclosure system to achieve partial priority construction for the foundation pit, the foundation pit is divided into a pre-construction region, a support replacement region and a post-construction region; the support replacement region is located between the pre-construction region and the post-construction region; each support in the foundation pit comprises a horizontal support that penetrates the pre-construction region, the support replacement region and the post-construction region, and a longitudinal support intersecting with the horizontal support; a support replacement structure for supporting the support replacement region is provided, so that a support of a corresponding layer of the pre-construction region may first be removed, and an underground structure of the corresponding layer of the pre-construction region may then be constructed, and thereby the priority construction of the partial region of the foundation pit may be implemented without needing the overall construction of the foundation pit to be complete, which thus meets the requirements for special construction periods.
