What are the new supporting technologies for foundation pits?

A new type of foundation pit support technology-prestressed fish-bellied foundation pit steel support,

The prestressed fish-bellied steel support technology for foundation pit is based on the principle of prestress. Aiming at the shortcomings of traditional concrete internal support and steel support in controlling the deformation of foundation pit, through a lot of engineering research and practical application, an internal support structure system for deep foundation pit support is developed. The system is composed of fish-bellied beam (high-strength and low-relaxation steel strand as the upper chord), brace, angle brace, column, cross beam, connecting rod, high-strength contact, prestressed loading device and other standard parts to form a plane.

Compared with the traditional concrete internal support and steel support, it greatly improves the overall stiffness and stability of the support system. Combined with remote real-time monitoring system, the displacement of foundation pit can be effectively and accurately controlled and the deformation of foundation pit can be greatly reduced. This technology has made a great breakthrough in the internal support technology of deep foundation pit support, and it is the most advanced internal support technology in the world at present.
