Support changing structure of deep foundation pit and construction method of support changing structure
The invention relates to a support changing structure of a deep foundation pit, a bottom plate of the foundation pit comprises an existing section, a to-be-cast section and a post-cast strip formed between the existing section and the to-be-cast section, the support changing structure comprises a supporting rod and a supporting rod, the supporting rod is embedded in the existing section, a part of the supporting rod protrudes towards the to-be-cast section, and the supporting rod is formed by pouring concrete; the reinforcing reinforcement cage is fixed at the end part of the supporting rod and is fixedly connected with the reinforcement cage of the to-be-cast section; and the reinforcing band is formed by pouring, and the reinforcing reinforcement cage is embedded in the reinforcing band. The problems that traditional profile steel support replacement is high in consumption and does not meet the green construction requirement are effectively solved, the concrete support replacement structure is used for replacing traditional profile steel, under the condition that force transmission is not affected, the construction period is shortened, the concrete support replacement structure is directly poured into a part of a bottom plate, and therefore the concept of green development is met.
本发明涉及一种深基坑的换撑结构，基坑的底板包括既有段、待浇段以及形成于既有段和待浇段之间的后浇带，换撑结构包括：埋设于既有段且有部分向待浇段凸伸的支撑杆，支撑杆由混凝土浇筑而成；固定于支撑杆的端部的加强钢筋笼，加强钢筋笼与待浇段的钢筋笼固定连接；以及浇筑形成的加强带，加强钢筋笼埋设于加强带内。本发明有效的解决了传统型钢换撑消耗大且不符合绿色施工要求的问题，通过使用砼换撑结构代替传统型钢，在不影响传力的情况下，缩短工期，且直接浇筑成为底板的一部分，从而符合绿色发展的理念。
