棱镜铅垂装置与顶管自动导向系统在顶管施工中的应用

Application of Prism Plumb Device and Pipe Jacking Automatic Guidance System in Pipe Jacking Construction

顶管施工工艺在市政雨污水排管、自来水供水排管、电厂取排水排管等领域得到了广泛运用。顶管施工过程中,确保顶管机沿设计轴线开挖是非常重要的。这就需要对顶管机的空间位置进行实时测量,以确定顶管机是否有偏离设计轴线的情况。以上海周邓公路污水干管完善工程为背景,阐述一种安装于顶管机内使测量目标棱镜始终铅垂的装置,该装置与顶管自动导向系统配合使用,在施工过程中可对顶管机进行实时定位测量,效果显著。

Pipe jacking construction technology has been widely used in municipal rainwater and sewage drainage pipe,tap water supply drainage pipe,power plant water intake and drainage pipe and other fields.In the process of pipe jacking construction,it is very important to ensure that the pipe jacking machine excavates along the design axis.It requires realtime measurement of the spatial position of the pipe jacking machine to determine whether the pipe jacking machine deviates from the design axis.Taking the improvement project of sewage main pipe of Zhoudeng highway in Shanghai as the background,a device installed in the pipe jacking machine to make the measuring target prism always plumb is expounded.The device is used in conjunction with the pipe jacking automatic guidance system,which can carry out realtime positioning and measurement of the pipe jacking machine during construction,and the effect is remarkable.
