非开挖导向钻进轨迹的设计原则与控制方法

The principles of design and the method of control no-dig guided boring trajectory

讨论了轨迹设计与控制的重要性,提出了需要做的准备工作,导向孔的设计埋深、出入土角、弯曲半径的设计原则,控制测量的方法、原则及纠偏的方法,以期减少工程事故,减少施工成本,缩短施工周期,取得更好的经济社会效益。

This article discusses the importance of the design and control of the track,and proposes the essential preparation work,the design principles of the deep burying,out of earth angle and the bend radius of the pilot hole.The article also proposes the methods and principles of control survey,and the methods of its correction,aimed at reducing engineering accidents,reducing construction costs,shortening the construction period,and gaining better economic and social benefits.
