Foundation pit supporting structure combined support replacing system

Abstract

The invention provides a foundation pit supporting structure combined support replacing system. A horizontal support is internally provided with a first reinforcing rib in the length direction. The first reinforcing rib is provided with a first exposed end exposed out of a first end of the horizontal support. The first end is used for being connected with a first waist beam in an abutting mode, and the first exposed end is used for being connected into the first waist beam in an inserted mode. A second end is connected with a spacer in an abutting mode. The spacer is used for being connected with a vertical outer wall in an abutting mode. A throwing support is obliquely arranged. A first tail end of the throwing support is higher than a second tail end of the throwing support. The throwing support is internally provided with a second reinforcing rib in the length direction and provided with a second exposed end exposed out of the second tail end. The second tail end is used for being connected with the vertical outer wall in an abutting mode, the second exposed end is used for being connected into the vertical outer wall in an inserted mode, and the first tail end is used for being connected with a second waist beam in an abutting mode. The foundation pit supporting structure combined support replacing system can eliminate the influence of inner support replacing on continuous construction of a main structure, reduces a plurality of intermediate procedures, shortens the construction period of a key line, accelerates the construction progress of the main structure, reduces construction cost and is suitable for being applied and popularized in a large scale.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to the technical field of support replacement for foundation pit support structures, and specifically refers to a combined support replacement system for foundation pit support structures. Background technique [0002] For deep foundation pit projects in areas with complex hydrological and geological conditions such as reclamation areas, due to the limitations and influences of construction space, hydrological and geological conditions, and construction technology, most of them adopt the combined support structure of "internal support + support piles". [0003] See Figure 1A As shown, the existing supporting system in the foundation pit includes an enclosure structure 1 (also called a support pile), a first waist beam 2, a second waist beam 3, a first inner support 4 and a second inner support 5, wherein The enclosure structure 1 is vertically arranged, the first wais...

AI Technical Summary

Problems solved by technology

In the process of removing and replacing the traditional inner support, the space position of the inner support will inevitably affect the continuous construction of the main structure, increase the construction cost and prolong the construction period

See Figure 1A to Figure 1D As shown, the conventional main structure construction process is: main structure construction→outer wall waterproofing→scaffold removal→fertilizer tank backfill→power transmission belt construction→internal support removal→continue main structure construction, and so on. The construction process includes external wall waterproofing, repeated scaffolding and dismantling, fertilizer tank backfilling, power transmission belt construction, internal support removal, etc., which affects the continuous construction of the main structure, increases construction costs, and prolongs the construction period
