The prestressed steel composite support technology adopted in the foundation pit support construction of Shanghai strong foundation is based on the principle of prestress, aiming at the shortcomings of traditional support, through a lot of engineering practice and application of the development of green deep foundation pit support system-Prestressed fish-belly steel bracing for foundation pit.
Prestressed steel composite support is made of steel components assembled on site. Compared with the traditional concrete support, it reduces the time of field die support and concrete curing. Steel components can be recycled, further saving costs and reducing industrial waste and noise.
Compared with the traditional steel bracing, the prestressed fish-belly steel bracing can eliminate most of the compression deformation of the bracing before excavation, thus improving the safety of the supporting structure and reducing the deformation of the foundation pit. In the process of excavation, the prestressed the stomach type steel structure can support supporting structure for soil and water pressure may produce the large or sudden construction load, prestressed measures such as adjusting by loading device, to ensure safety and control of retaining structure deformation of the surrounding, effectively protect the foundation pit surrounding building, material, municipal roads and pipelines such as environmental safety; Compared with the traditional support, the fish belly beam structure uses less steel components, which provides sufficient construction space, improves the construction conditions of underground engineering, and also facilitates excavation, soil transport and demolition of foundation pit, thus reducing the cost 20%Above, the installation, demolition, excavation and underground structure construction period is shortened40% The above.
