某新建高层住宅小区东西长367m,南北宽152m,由12幢22至26层的高层住宅和地下车库组成,采用先主楼后车库的施工顺序,依据地勘和水文资料,通过合理布井降水,采用平衡降水方法控制主楼的沉降变形,保证主楼安全,效果良好。根据工程实践,现将施工过程控制措施介绍如下。一、降水井的布置1.熟悉工程水文地质与基础设计依据地勘报告和现场开挖情况,拟开
The newly built high-rise residential district is 367m long and 152m wide from north to south. It consists of 12 high-rise residential buildings with underground floors from 22 to 26 storeys and an underground garage. According to the construction sequence of the main garage behind the main building and based on geological survey and hydrological data, Balance precipitation method is used to control the settlement of the main building and ensure the safety of the main building with good effect. According to engineering practice, the construction process control measures are introduced below. First, the placement of precipitation wells 1.
