Details >As a measure of foundation pit support, prestressed steel composite support is more and more used in foundation pit engineering projects as the surrounding environment of foundation pit becomes more and more complex and the underground space is used more and more fully today.
Details >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, and developed through a lot of engineering practice and application of green deep foundation pit support system - PREstressed fish-belly FOUNDATION pit steel support.
Details >Prestressed steel composite support compared with traditional concrete support, because is to use steel component assembly, don't need to carry on the in situ conservation, in the last stage, the steel members is also more convenient dismantling is reinforced concrete, shorten construction period, reduce the construction noise, and steel component reuse, recycle to reduce the cost, Meet the environmental requirements of energy conservation and emission reduction.
Details >Compared with the traditional steel composite bracing, prestressed steel composite bracing increases the construction procedure of applying prestress. The steel support of prestressed fish-belly foundation pit adopts special fish-belly beam structure. Under the premise of ensuring the construction quality, it further reduces the number of steel components, provides a more open construction space, makes the construction of earth digging, earth transport and underground structure more convenient, improves the construction period as a whole, and reduces the cost at the same time.
Details >Compared with the traditional steel composite bracing, the prestressed steel composite BRACING improves the overall stiffness and stability of the bracing system, and improves the safety of the foundation PIT bracing structure. Shanghai strong foundation prestressed fish belly & NBSP; The foundation pit steel support technology adopts prestressed fish-belly beam structure, which further reduces the number of steel members, provides open construction space, and makes excavation, transportation and underground structure construction more convenient.
Details >The prestressed steel composite support of Shanghai strong foundation adopts special fish-belly beam structure. This structure can reduce the use of steel components, significantly improve the construction conditions of underground space while ensuring the construction quality. Compared with the traditional support technology, the cost is reduced by more than 20%. The construction time of installation, demolition, excavation and underground structure is saved by 40%. The above.
Details >Prestressed concrete steel composite support relative to support more economic and environmental point in recycling of steel structure can be dismantled, compared with ordinary steel composite support, prestressed steel composite support need to release the prestressed before dismantling, Shanghai strong foundation prestressed steel belly type foundation pit support in ensuring construction quality under the condition of same, use less of steel members, It can provide more construction space, improve construction efficiency, shorten the construction period and reduce the cost.
Details >Recently, Shanghai strong foundation engineering co., LTD. (hereinafter referred to as the "Shanghai" strong foundation) conducted once a year the technician orientation, production vice general manager Zhou Youwang Li Jian, safe environmental protection, technology, quality manager, vice manager li small lift and administrative personnel section chief Lu Lu, engineer Xie Jiantao with 18 new technician participation.
Details >Section steel composite support is composed of standardized steel members, fast installation; No maintenance & NBSP; . The PRESTRESSED fish-BELLY FOUNDATION PIT steel support technology of Shanghai strong foundation consists of fish-belly beam, counter brace, Angle brace, column, beam, contact bar, high-strength contact, prestressed loading device and other standard components. Compared with the traditional support system, the steel components are reduced. Volume, support costs and construction costs have been reduced by more than 30%. The site acceptance and yard of steel components are also very important.
