Study Of Structure Design And Construction Method Of Foundation Pit Support In Filling Sea Area

With the rapid development of economic and speeded-up of urbanization, the demand for resources of land increasingly urgent, people gradually refocus their eyes to the coastal area, constantly push forward the coastline, to expand the land area by artificial reclamation. At the same time, there is also some coastal cities need open up new land along the coast because the pressure of the development of the land for construction is limited, economic development and other factors. In short,Sea Reclamation has become an effective way to ease the shortage of land resource in coastal city. However, the particularity of reclaimed land geological conditions increased the difficulty of construction and other underground excavation engineering, to ensure the construction quality and the construction process of underground engineering safety, we must effective control ground water, eliminate security risks, reduce economic losses and ensure that the project completed efficiently and safely, by formulate and select possible construction schemesThis article on how to control the reclamation of groundwater, and deal with unexpected problems at any time during the construction process to make a little research:(1) Design of deep foundation. Mainly on anti-drain pit, piles and engaging the inner support for the design, combined with problems encountered in the construction, summed up the foundation pit design elements, and for the reclamation of the geological characteristics were studied as a seal bite pile Curtain in effect during the construction pit and bite pile construction process control points.(2) Heavy and difficult problems. In this paper, the project encountered in practice two heavy and difficult works are summarized, combined with the construction proposed solutions for the future reclamation project to provide the same type of important lessons.(3) Deep Pit Construction. The main measures to support the foundation pitexcavation construction methods are discussed, the construction of the high water level in response to the reclamation area taken for a more detailed description can be made to guide the future construction of the same type.(4) Data measured. Pit measured data combined with the proposed project,deformation monitoring excavation structure, systematic introduction to the principles of construction monitoring, content, frequency, and to monitor the value of the existing norms Foundation were analyzed, and for Wall retaining structure horizontal displacement monitoring, and ultimately determine the applicability of the method.
