The traditional steel support is widely used in subway and foundation pit. The prestressed fish-belly steel structure support technology is a kind of deep foundation pit internal support structure system developed based on the principle of prestress.
Strong foundation has obtained dozens of innovative technologies in pile foundation engineering, foundation pit engineering, water foundation treatment, land foundation treatment, and has been authorized invention patents54Item, Utility model patent82Item, Appearance design7To promote industrial technological progress as the way of enterprise survival, more than 20 years, in each different period, with continuous innovation results to support the development of enterprises.
A,Conventional steel support
Process principle:
Traditional steel support refers to the use of steel pipes,HSection steel, Angle steel and other engineering structures to enhance the stability of the general situation is inclined connecting members, the most common are herringbone and cross shape, is widely used in the subway, foundation pit enclosure.
Advantages of process:
(1Composed of steel components, easy to install and disassemble;
(2) can be reused,Reduce construction waste generation,Cost savings,Green environmental protection.
Second,Prestressed fish-belly steel bracing for foundation pit
Process principle:
The prestressed fish-belly foundation pit steel structure supporting technology used by our company is based on the principle of prestress,For traditional concrete support, steel support of foundation pit deformation control ability, through a large number of engineering research and application practice, developed a kind of deep foundation pit support structure within the system, it is composed of the stomach beam bent (high strength low relaxation of steel strand as a component), the tide, horn, column, beam, link rod, high strength contact, prestress loading devices such as standard parts, Forming plane prestressed support system and three-dimensional support structure system.
Advantages of process:
(1) improve the safety degree of foundation pit supporting structure and reduce the deformation of foundation pit;
(2) Reduce the impact of underground space on the surrounding environment, and component materials can be recycled and reused;
(3) compared to traditional supportcostTo reduce20%, the construction period of underground structure is shortened40%.
