Document Type and Number:
WIPO Patent Application WO/2022/016720
Kind Code:
A1
Abstract:
The present invention relates to the technical fields of foundation pit support construction and earth excavation. Disclosed is a temporary passage construction method employing a support structure in a deep foundation pit. The method comprises the following steps: S11, constructing a first intra-layer support; S12, constructing a first-stage temporary ramp, and excavating a first layer of earth to the bottom of a second intra-layer support; S13, constructing the second intra-layer support, and performing pouring to form a first-stage variable slope platform between support beams of the second intra-layer support, wherein the first-stage variable slope platform communicates with the first-stage temporary ramp; S14, constructing a second-stage temporary ramp, and excavating a second layer of earth to the bottom of a third intra-layer support; S15, constructing the third intra-layer support, and performing pouring to form a second-stage variable slope platform between support beams of the third intra-layer support, wherein the second-stage variable slope platform communicates with the second-stage temporary ramp; and S16, in the same manner as in steps S12 to S15, performing construction downwards in a foundation pit until the excavation reaches the bottom of the foundation pit. The temporary passage construction method employing a support structure in a deep foundation pit provided by the technical solution of the present invention greatly reduces time, conserves manpower, and reduces costs.
