Research On The Design And Construction Technology Of Deep Foundation Pit Support In Tian Jin He Chang Yuan Project

The rapid development of urban process in China in recent years, prompting the city infrastructure construction scale, the urban population increase gradually increased for senior, tall building project increased substantially. But because the land scarcity, making many of the senior project within the city to underground to space must be. Therefore, making full use of underground space of deep excavation engineering, including increased as the assistant engineering supporting structure is the guarantee of deep foundation pit engineering excavation and permanent building normal construction key link. Based on the deep foundation pit bracing structure design for a series of basic theory, the actual project where garden project from construction condition, cost, time limit, for feasibility schemes are set, ultimately through than plane unit calculation, soil economical and elastic resistance method calculation method in concrete design of retaining piles of deep foundation pit supporting supporting structure system. Meanwhile put forward for foundation pit bracing structure during the construction of key nodes corresponding technical measures and emergency plan etc and the purpose of monitoring solution of foundation pit discussed and conclusion analysis.
