地下立体交通箱涵管幕双重置换自动导向技术研究

Automatic Guidance Technique of Pipe Replaced by Box Culvert Jacking Process in Underground 3D Traffic

为适应地下立体交通工程箱涵顶进置换管幕施工的新方法,研究开发了一套以自动全站仪为主的智能导向系统。介绍了该智能导向系统的原理及关键技术,并结合该系统在上海金山既有铁路下顶进公路箱涵工程的顺利完成和成功应用,表明了该系统在实际施工中的优越性与实用性,具有自动化程度高、可靠性强、测量精度高的特点,可以为纠偏提供实时偏差信息,达到信息化施工的目标。

In order to adapt new underground 3D traffic method of pipe replaced by box culvert jacking process,a set of automatic guidance system based on total station was developed.This paper introduced the principle and key techniques of this system,and combined with successful application of culvert jacking highway under the existing railway project in Shanghai Jinshan.In actual construction this system proved to be excellent and have the following features：automatic,reliable,accurate,and it could provide real-time deviation for correction to achieve information construction.
