Non-excavation pipe jacking construction method for crossing rock stratum
The invention provides a non-excavation pipe jacking construction method for crossing a rock stratum. The non-excavation pipe jacking construction method comprises the steps of building a construction control network, excavating a working well, installing a back wall, installing a guide rail in the working well, excavating a pilot tunnel, laying the guide rail in the pilot tunnel, extending a jacking pipe, grouting the pipe, dismantling the jacking pipe and the like. According to the method, a pipe jacking machine is not needed for construction, small-distance rock stratum pipe jacking construction is met, the adaptability to the pipe jacking section, the gradient and the trend is high, the construction cost is low, the construction period is controllable, the tunneling length per day is 1 m/d, stratum deformation is small, the excavation contour control is good, the pipe joint installation quality is controllable, and the construction safety is high.
本发明提供一种穿越岩层的非开挖顶管施工方法，包括建立施工控制网、开挖工作井、安装背墙、安装工作井内导轨、导洞开挖、铺设导洞内导轨、顶管延伸、管道注浆、顶管拆除等步骤。本发明无须采用顶管机施工，满足小距离岩层顶管施工，对顶管断面、坡度、走向适应性强，施工成本低，工期可控，每天掘进长度1m/d，地层变形小，开挖轮廓控制良好，管节安装质量可控，施工安全性较高。
