Problems solved by technology

Such a construction method undoubtedly increases the difficulty of construction, which is mainly manifested in: 1. It is extremely difficult to transport the concrete blocks produced during the chiseling of the sealing enclosure out of the basement, and it generally needs to be transported several times to the reserved opening of the structure; The main machinery, first, the crusher is extremely easy to cause damage to the constructed structure, the construction noise is large, and the dust pollution is serious
The second is that although mechanical cutting and demolition can protect the structure, it is expensive and the construction period is slow, and it cannot achieve good economic benefits, so it is not widely used
Even if it is removed by cutting, it needs to be broken by a crusher before it can be transported out of the basement. It also has the disadvantages of being extremely easy to cause damage to the constructed structure, and the construction noise is large and the dust pollution is serious.
3. The partition wall sandwiched between the two foundation pit structures needs to be dug out from between the structures, which can only be removed manually, and other high-efficiency demolition mechanical tools cannot be used, so the construction efficiency is low and the operating surface is greatly restricted

Embodiment Construction

[0019] The method for removing the partition wall between foundation pits under the semi-reverse method of the present invention will be further described in detail below.

[0020] see Figure 1 to Figure 4 , this embodiment discloses a method for dismantling the partition wall between foundation pits under the semi-reverse method, which is used to remove the partition wall 2 between the foundation pit structure constructed first and the foundation pit structure constructed later, characterized in that it includes the following steps :

[0021] The first step is to construct the foundation pit structure first; after the construction of the foundation pit, after the earthwork excavation is completed, the structure is built back from the bottom plate structure upwards, and the foundation pit structure plate 4 and the partition wall 2 are constructed after each layer from the bottom plate structure There is a space for the post-casting tape that runs through from bottom to top, ...

Abstract

The invention provides a method for dismantling a division wall between foundation pits in a semi-reversed construction mode. The method is used for dismantling the division wall between an early-constructed foundation pit structure and a post-constructed foundation pit structure. The method includes the steps that the early-constructed foundation pit structure is constructed firstly; after earth excavation of the post-constructed foundation pit is completed, the structure is reconstructed upwards from a base plate structure, and the vertically-interpenetrating post-pouring belt space is reserved between each layer of the post-constructed foundation pit structure and the division wall from the base plate structure; the division wall is cut into concrete blocks convenient to hoist from bottom to top, and then a crane is utilized to directly hoist the concrete blocks out of the post-pouring belt space of the post-constructed foundation pit structure. Through the arrangement of the post-pouring belt space, the method has the advantages that the method enables the division wall to be dismantled more conveniently, effectively reduces construction cost, accelerates construction progress, saves resources, and has the effect of low-carbon construction.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for removing a partition wall between foundation pits under the semi-reverse method. Background technique [0002] With the continuous development of modern building construction technology, the underground structure is also developing into a diversified structure. The semi-inverted method technology has been adopted by more and more projects. In line with different functional requirements, the multi-foundation pit connection design has brought new challenges to underground engineering construction. Greater difficulty. [0003] At present, the construction plan for the construction of underground structures in adjacent foundation pits that needs to achieve structural connection is to complete the underground structure in two foundation pits, and the separation wall between the two foundation pits cannot be used in the construction of the two foundation pit structures...
