摘要
北京地区地质与水文条件复杂,为提高盾构施工的安全性,在施工前对施工环境进行详细的分析与调查,组织专门的调查小组,收集工程范围内的所有管线图和竣工资料,在地下管线档案出现遗漏或位置不准确的情况下进行现场探测,并充分利用超前地质预报及地质保障技术,在施工前将所有地下空洞探测清楚。
Beijing has complex geological and hydrological conditions, including dense high-rise buildings and many highways, railways, rivers and lakes. In order to improve the safety in shield construction, detailed analysis and surveys on construction environment are carried out before construction, and special survey group is organized to collect data on all pipeline drawings and completion document within the project scope. Field survey is carried out where relevant data show that underground pipeline leaks or the position is inaccurate. All underground hollow spaces are detected through using advanced geological prediction and geological protection techniques before construction.
