摘要
介绍了盖挖逆作法地铁车站中间桩柱施工定位装置的应用、使用方法以及中间桩柱的施工原理、工艺流程、格构柱倾斜量测等施工技术,通过大量实践证明:应用定位装置来寻找桩柱的中心位置,可以很好地解决地下车站施工的难题。
l^is paper introduces the application, application method, construction principle, process flow, lattice column inclination measurement and other construction techniques of the intermediate pile construction positioning device in the subway station with top down method. Through a large number of practices, it is proved that using the position device to find the center of the piles, can be a good solution to this problem underground station construction.
