Support changing device for dismantling shared enclosure structure of adjacent foundation pits and construction method of support changing device

Abstract

The invention relates to a support changing device for dismantling a shared enclosure structure of adjacent foundation pits and a construction method of the support changing device. The device comprises a first embedded part, a first steel support, a second embedded part, a second steel support and filling structures, wherein the first embedded part is embedded and fixed to the end part, close to the enclosure structure, of a first main body structure in a first foundation pit; the first steel support is horizontally and fixedly connected between the first embedded part and main reinforcements of the enclosure structure; the second embedded part is embedded and fixed at the end part, close to the enclosure structure, of a second main body structure in a second foundation pit; the second steel support is horizontally and fixedly connected between the second embedded part and the main reinforcements of the enclosure structure; and the filling structures are plugged in gaps among the end part of the first steel support, the end part of the second steel support and the main reinforcements of the enclosure structure. The first steel support and the second steel support are oppositely connected to the two sides of the enclosure structure, connection of the structures on the two sides is enhanced through the filling structures, a force transmission system is formed, normal force transmission of the structures is guaranteed, and the safety of foundation pit construction is guaranteed. The device can be dismounted through cutting, and construction is convenient.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a support changing device and a construction method for dismantling a shared enclosure structure of adjacent foundation pits. Background technique [0002] Two adjacent foundation pits are usually provided with a common enclosure, such as bored piles or ground connection walls. According to the construction conditions, the foundation pit construction is completed first, and then the foundation pit is excavated after excavation. [0003] refer to figure 1 It is a schematic diagram of the construction state of the shared enclosure structure of adjacent foundation pits in the prior art. to combine figure 1 As shown, a common enclosure structure 30a is set between the foundation pit 10a excavated ahead and the foundation pit excavated later 20a. The multi-layer structural slab 11a is constructed in the foundation pit 10a ahead. A reinforced concrete force transmission belt 1...
