Prestressed reinforced concrete supporting structure and construction method thereof
The invention provides a prestressed reinforced concrete supporting structure which comprises at least one layer of horizontal support, each layer of horizontal support at least comprises a horizontal beam, at least one horizontal beam comprises at least two structural sections, and the structural sections of the same horizontal beam are connected in sequence. The adjacent structural sections of the same horizontal beam are connected into a whole through a post-pouring main supporting beam, the post-pouring main supporting beam is constructed after prestress is applied to the adjacent structural sections, and each structural section is of a reinforced concrete structure. The invention further provides a construction method of the prestressed reinforced concrete supporting structure. The horizontal beam is divided into at least two structural sections, and the structural sections are connected into a whole after prestress is applied to the structural sections, so that the complete horizontal beam is formed. The problems that an existing reinforced concrete supporting structure can only passively resist the external soil pressure of the foundation pit and the deformation of the foundation pit is large due to the fact that no prestress exists can be smoothly solved, and the safety of foundation pit construction is improved.
本申请提出了一种预应力钢筋混凝土支撑结构，其包括至少一层水平支撑，每一层水平支撑至少包括一架水平梁，至少有一架水平梁包括至少两个结构段，同一架水平梁的各结构段顺序相接，同一架水平梁的相邻结构段经后浇主撑梁连接为一体，该后浇主撑梁是在对相邻结构段完成预应力施加后施工完成的，各结构段均为钢筋混凝土结构。本申请还提出了该预应力钢筋混凝土支撑结构的施工方法。本申请将水平梁分割为至少两个结构段，并在对各结构段完成预应力施加后连接为一体，形成一个完整的水平梁。本申请能够顺利地解决现有钢筋混凝土支撑结构由于没有预应力所导致的只能被动抵抗基坑外部土压力，基坑变形大的问题，提高了基坑施工的安全性。
