摘要
北京农展南路热力外线工程1-2号段隧道与待建地铁朝阳公园车站设计结构高程相冲突,采用承托平台跨越地铁预留车站技术,在热力管沟下方做一个承托平台,平台上部做热力管沟,平台下部同期施做承托平台的格构柱及其桩基础、车站主体的围护桩、竖向支撑桩及阻水旋喷桩,保证了地铁车站在平台下方正常施工,满足了热力管沟结构安全及管线后期正常运行及维护。
The elevation of exterior heating pipeline no.l-2 segment tunnel on Nongzhan South Road of Beijing conflicts with the design structure of the planned Chaoyang Park Subway Station, so bearing platform crossing reserved subway station technique was adopted. A bearing platform under the heating pipeline trench and those simultaneously built under the platform included lattice column, pile foundation, enclosure pile for the main structure of station, vertical support and water-stop rotary spray pile. Smooth construction under the platform was guaranteed, satisfying the requirements for structural safety and normal operation and maintenance of the heating pipeline trench.
