Pipe jacking construction method for underneath passing expressway open channel
The invention belongs to the technical field of pipe jacking construction, and particularly relates to a pipe jacking construction method for an open channel of an underneath pass expressway, which comprises the following steps of: 1, manufacturing a blade foot and an open caisson, namely manufacturing the blade foot, well body reinforcing steel bars, a bracket, a template and concrete, and temporarily plugging a reserved hole by adopting a brick wall made of brick Mu20 bricks and M10 cement paste; secondly, the well body is excavated for sinking, and sinking can be started when the concrete strength of the open caisson reaches 100% of the design strength. According to the pipe jacking construction method for underneath passing the open channel of the expressway, when a slurry balance pipe jacking machine inclines, a laser receiver can not receive light rays, a circumferential dynamic inclination detection mechanism can be controlled to do circumferential motion to detect the inclination direction, and therefore a corresponding inclination deviation correction driving mechanism is controlled to conduct deviation correction operation; therefore, drilling dislocation caused by deviation of the drilling angle is avoided, construction efficiency is improved, real-time monitoring and deviation correction can be conducted on the tool bit in time, and the axis, the elevation and the linetype of the pipeline are guaranteed to the maximum degree.
本发明属于顶管施工技术领域，尤其是一种下穿高速公路明渠顶管施工方法，包括：步骤一、刃脚及沉井制作，包括刃脚以及井身钢筋、支架、模板和混凝土，预留洞口采用砖砌Mu20砖及M10水泥浆的砖墙临时封堵；步骤二、井身挖土下沉，沉井混凝土强度达到设计强度100％时可开始下沉。该下穿高速公路明渠顶管施工方法，在泥水平衡顶管机发生倾斜时激光接收器接收不到光线即可控制圆周动态倾斜检测机构进行圆周运动检测倾斜方向，从而控制对应的倾斜纠偏驱动机构进行纠偏操作，进而避免钻孔角度发生偏移导致钻孔错位，从而增强了施工的效率，能够及时对刀头实时监控及纠偏，最大程度的保证管道的轴线、标高及线型。
