Man-machine opposite-roof non-excavation pipe burying construction method
The invention discloses a man-machine opposite-roof non-excavation pipe burying construction method which comprises the following steps: extracting the position of a pipe jacking working well according to the requirement of a designed pipeline position, and determining the positions of the two working wells through lofting of an RTK (Real Time Kinematic) measurement system or a total station; after the working position is determined, according to geological structure characteristics shown by a geological exploration report, a Larsen steel sheet pile or reinforced concrete form can be adopted for a pipe jacking working well according to geological conditions and design requirements, the size of a mechanical tunneling working well is 11.5 m * 8.5 m, the size of a manual tunneling working well is 9.5 m * 7.5 m, and the size of the working well is determined according to equipment, the pipe diameter of a pipeline and the working space. And the back wall adopts assembly type reinforcing equipment. The construction method has the beneficial effects that a synchronous opposite construction method of manual tunneling and mechanical tunneling is adopted, so that the dismantling and excavation operation area of the existing public infrastructure is effectively reduced under the condition that the construction period is greatly shortened.
本发明公开了人机对顶非开挖埋管施工方法，包括根据设计管线位置的要求，提取顶管工作井的位置，通过RTK测量系统或者全站仪放样确定两工作井的位置；确定工作位置后，根据地勘报告所示地质结构特点，顶管工作井根据地质情况和设计要求可采用拉森钢板桩或钢筋混凝土形式，机械掘进工作井为11.5m*8.5m，人工掘进工作井的的尺寸为9.5m*7.5m，工作井的尺寸根据设备、管道管径及作业空间确定，后背墙采用装配式加固设备。本发明的有益效果是，本工法采用人工掘进、机械掘进同步对向施工工法，大大缩短施工周期的情况下，有效的减少了对既有公共基础设施的拆除和开挖作业面积。
