Prestressed section steel-reinforced concrete combined support and construction method thereof
The invention discloses a prestressed section steel-reinforced concrete combined support and a construction method thereof, and aims to provide a prestressed section steel-reinforced concrete combined support which can greatly reduce elastic compression deformation, creep deformation and shrinkage deformation of a concrete support, can greatly reduce the stress level of a passive area soil body in a pit, and can improve the construction efficiency. And therefore, the deformation of the foundation pit is reduced. A prestressed steel-reinforced concrete combined support comprises a first construction section concrete supporting beam, a second construction section concrete supporting beam and a steel-reinforced concrete beam, and one end of the first construction section concrete supporting beam is connected with an enclosure wall through the prestressed steel-reinforced concrete beam; the prestressed steel reinforced concrete beam comprises a prestressed pressurizing device, a profile steel supporting beam and concrete, the prestressed pressurizing device comprises a prestressed pressurizing component and a force retaining box, and the prestressed pressurizing component is used for applying prestress between the concrete supporting beam and the enclosure wall at the first construction section; the force retaining box is used for locking the prestress pressurizing component to apply prestress.
本发明公开了一种预应力型钢钢骨混凝土组合支撑及其施工方法，旨在提供一种能大幅减小混凝土支撑的弹性压缩变形、徐变变形和收缩变形，同时能大幅降低坑内被动区土体的应力水平，从而减小基坑变形的预应力型钢钢骨混凝土组合支撑及其施工方法。一种预应力型钢钢骨混凝土组合支撑，包括：先行施工段混凝土支撑梁,先行施工段混凝土支撑梁的一端通过预应力钢骨混凝土梁与围护墙连接；预应力钢骨混凝土梁，其包括预应力加压装置、型钢支撑梁及混凝土，预应力加压装置包括预应力加压构件及保力盒，其中预应力加压构件用于在先行施工段混凝土支撑梁与围护墙之间施加预应力，保力盒用于锁定预应力加压构件施加预应力。
