既有深基坑内对已完桩筏基础改造技术应用

Deep within the existing pit of piled raft foundation has completed the transformation of technology applications

随着城市的发展进程,大量的既有建筑需要进行地基基础加固改造。背景工程在无先例可循的条件下,通过科技创新克服了既有深基坑内对已完桩筏基础改造的施工难题,填补了部分施工技术领域的空白,为今后类似工程施工提供借鉴。

With the process of urban development,a large number of existing buildings require reinforcement of foundation.Works in the context of the conditions precedent to follow,through technological innovation to overcome the deep pit within both of the completed construction of piled raft foundation transformation puzzle,fill the blank part of the technology in the field of construction,provide a reference for future similar projects.
