Adjacent deep and shallow foundation pit support system and construction method
The invention relates to an adjacent deep and shallow foundation pit support system and a construction method. The adjacent deep and shallow foundation pit support system is composed of a foundation pit support system A and a foundation pit support system B; top beams on the two sides of the foundation pit support system A and the foundation pit support system B are connected through reinforced concrete connecting beams to form a double-row pile support structure, and it is guaranteed that the two foundation pit support systems can deform in a coordinated mode; and an inclined throwing support is arranged on the side, adjacent to the foundation pit A in the foundation pit support system A, of the foundation pit B in the foundation pit support system B. The double-row pile support structure is formed by connecting the two foundation pit support piles through the reinforced concrete connecting beams, and the technical problem that when the foundation pits are close to each other and the excavation depths are inconsistent, internal force and deformation generated by excavation adjacent to the foundation pits affect each other and are overlapped with each other to cause instability of a support system in an existing foundation pit structure can be solved.
本发明涉及一种紧邻深浅基坑围护体系及施工方法，该体系由A基坑围护体系和B基坑围护体系构成；所述A基坑围护体系和B基坑围护体系的两侧冠梁通过钢筋混凝土连梁相连形成双排桩围护结构，保证两个基坑围护体系能协调变形；所述B基坑围护体系中的B基坑与A基坑围护体系中的A基坑相临侧设置斜抛撑。本发明采用两基坑围护桩通过钢筋混凝土连梁相连形成双排桩围护结构，能够解决现有基坑结构存在的在基坑相距较近且开挖深度不一致时，紧邻基坑开挖产生的内力与变形会相互影响,相互叠加,造成支护体系失稳的技术问题。
