Deep foundation pit inverted arch prestressed concrete supporting structure and building method thereof
The invention discloses a deep foundation pit inverted arch prestressed concrete supporting structure and a building method thereof. The supporting structure comprises a foundation pit fender post wall, a concrete waist beam, a concrete supporting beam, and a concrete ring beam; the foundation pit fender post wall is used for installing the concrete waist beam; the concrete waist beam which is used for mounting the concrete ring beam; the concrete waist beam is tightly attached to the inner wall of the foundation pit fender pile wall; the concrete supporting beam is used for supporting the concrete ring beam; the first end of the concrete supporting beam is connected with the inner wall of the concrete waist beam, the second end of the concrete supporting beam is connected with the concrete ring beam; the concrete ring beam is used for installing a concrete formwork so as to pour concrete and form a deep foundation pit; and the outer side wall of the concrete ring beam is connected with the concrete formwork. According to the deep foundation pit inverted arch prestressed concrete supporting structure and the building method thereof, on one hand, before and in the excavation processof the foundation pit, the deformation of the foundation pit is controlled by applying prestress in a grading mode, so that the surrounding environment protection grade is improved; and on the otherhand, by arranging the ring beam and a prestressed inverted arch beam, the integrity of the horizontal supporting structure is improved, the section of the ring beam can be reduced, and the number oftree supporting piles is reduced.
一种深基坑反拱预应力混凝土支撑结构及其搭建方法，所述支撑结构包括：基坑围护桩墙，用于安装混凝土腰梁；混凝土腰梁，用于安装混凝土环梁；所述混凝土腰梁紧贴所述基坑围护桩墙内壁；混凝土支撑梁，用于支撑所述混凝土环梁；所述混凝土支撑梁第一端与所述混凝土腰梁内壁连接而第二端与所述混凝土环梁连接；混凝土环梁，用于安装混凝土模板，以浇筑混凝土并形成深基坑；所述混凝土环梁外侧壁与所述混凝土模板连接。本申请一方面，在基坑开挖前和开挖过程中，通过分级施加预应力控制基坑变形，提高周边环境保护等级；另一方面，通过设置环梁和预应力反拱梁，提高水平支撑结构整体性，且可减小环梁的截面，减少树托桩的数量。
