Deep Foundation Pit Construction On The Surrounding Buildings On The Impact And Control

With the rapid development of China’s economy and city construction, more and more high-rise buildings, the depth of the pit is composed of5m,7m slowly to the9m, more than18m. With the high-rise building construction, influence of dewatering of foundation pit on the surrounding buildings has gradually aroused widespread concern in the community, precipitation less time is half a year, more than a year and a half, bring the settlement deformation, cracks in the wall, foundation settlement, tilt housing and underground pipelines cannot be used normally in varying degrees on the surrounding buildings, the cause the work stoppage, economic disputes, residents of collective complaints of group events, bring huge economic losses to the development of enterprises, but also have a tremendous impact on the surrounding residents, at the same time to social harmony with unstable factors. Therefore, we should be fully aware of deep foundation pit dewatering is not only the construction unit attaches great importance to the issue, but the development of company must carry out overall planning and coordination of the entire development project, from all angles of global research on deep foundation pit construction, system analysis of influence on Zhou Bianjian built the deep foundation pit construction, research solutions starting from the design phase of the project, is real estate enterprises must face the issue.This paper stands in the perspective of the construction unit, according to the actual situation of Ji’nan triumphant return to the new east area of foundation pit engineering as the background, from the whole project development height, from basic design scheme, design of high-rise building project, precipitation water monitoring design, foundation pit engineering quality control measures, emergency plan, selection of construction unit, design project node, coordination of government the competent departments and neighborhood relations, has carried on the system design and research, the deep foundation pit excavation depth is reduced, shortening the precipitation time, minimize the generation of deep foundation pit construction on the surrounding buildings influence measures, the enterprise provides guarantee measures can draw on the safety of foundation pit construction, which has good application value, the realization of social residents, enterprises, sharing a win-win situation.
