theprojectLocated on the ancient road of Yongding River,It is located in the core of Beijing, close to the office building of Ministry of Housing and Urban-Rural Development, PRC, surrounded by numerous buildings, roads and municipal pipelines, as well as foundation pitsThe excavation depth reaches 25.1m .The construction site is narrow and small, and the quality requirements, as well as the transport out of the earth are very largeThe challenge.
The foundation pit of the project adopts the steel support technology of prestressed fish-belly foundation pit. Compared with the traditional concrete support, this technology has the following advantages:
(1) adopt standardized components, bolt connection, on-site installation and disassembly,Construction speed is fast,The noise is small;Components can be recycled, no construction waste, green environmental protection.
(2)Prestressed fish-belly steel supports apply sufficient prestress before opening of the foundation pit. Most of the compression deformation of the support is eliminated, so as to improve the safety of the foundation pit supporting structure. Reduces the deformation of the foundation pit,Adjust the prestress by loading device and other measures . It can ensure the safety of supporting structure and control the deformation of surrounding soil . Effectively protect the foundation pit surrounding construction ( constitutive ) Environmental safety of buildings, municipal roads and pipelines.
(3) The steel support arrangement can provide larger construction working face, convenient and quick excavation, and at the same timeReduce the installation, demolition and earthwork excavation period of the enclosure structure.
