Reverse operation construction rapid channel sinking culvert construction method
The invention relates to a reverse operation construction rapid channel sinking culvert construction method. A sinking culvert is located below a road surface of a rapid channel. The construction method comprises the following steps of S1, obtaining precast piles and precast beams; S2, segmenting the road surface of the rapid channel; S3, performing piling construction; S4, performing high-pressure grouting; S5, mounting pavement beams and recovering the road surface of the rapid channel; S6, reducing the water level of the sinking culvert; S7, excavating the sinking culvert; S8, performing pouring; S9, mounting water collecting and draining systems; and S10, performing pipe sealing and pressure bearing. A segmented construction method is adopted, a passage road for pedestrians is reserved, and inconvenience brought to the pedestrians due to road sealing is avoided; the precast piles are used as vertical walls, so that cantilever supporting piles can be omitted; the precast beams are used as road surface structures, so that the construction progress is fast, and the manufacturing cost is low; and the required precast piles and the required precast beams are poured and formed outside a construction site, so that the problems that the road surface closing time is too long and the road surface area is occupied due to pouring and forming in the construction site are solved.
本发明涉及一种逆作业施工快速通道下沉涵洞施工方法，下沉涵洞处于快速通道路面下方，所述施工方法步骤为：S1：预制桩和梁，S2：快速通道路面分段，S3：打桩施工，S4：高压注浆，S5：安装路面梁并恢复快速通道路面，S6：下沉涵洞的降水位，S7：下沉涵洞的挖掘，S8：浇筑，S9：集水、排水系统安装，S10：封管承压，采用分段施工的方法，保留有行人的通行道路，避免封闭道路给行人带来的不便；预制桩用作竖向墙体，可以节省悬臂支护桩，用预制梁做路面结构，施工进度快，造价低；在施工场地外浇筑成型所需的预制桩与预制梁，避免在施工场地内浇筑成型导致路面封闭时间过久、占用路面面积的问题。
