摘要
杭州市某市政工程地下综合管廊与道路提升改造工程分别立项建设,结合地下综合管廊建设“规划先行、适度超前、因地制宜、统筹兼顾”的原则,地下综合管廊已建设完成。现需在地下综合管廊附近施工桥梁桩基础,通过对地下综合管廊超前处理、桥梁桩基采取永久钢护筒保护施工技术措施。不仅对桥梁桩基成孔施工防塌孔,同时减小桩基施工对成型管廊的振动与干扰。
The underground comprehensive pipeline Gallery of a municipal project in Hangzhou and the road elevation and transformation project have been constructed separately.The underground comprehensive pipeline Gallery has been completed according to the principle of“planning first,moderately leading,adapting measures to local conditions and overall consideration”.It is necessary to construct the bridge pile foundation near the underground comprehensive pipe gallery.Through the pre-treatment of underground comprehensive pipe gallery and the protection construction technology of permanent steel barrel for the bridge pile foundation,not only the collapse prevention for the hole-forming construction of the bridge pile foundation,but also the vibration and interference of the pile foundation construction to the formed pipe gallery are reduced.
