Abstract:The rectangular pipe jacking method is widely used in the construction of urban municipal engineering such as underground utility tunnel, pedestrian passage and vehicle passage. Compared with the construction of most rectangular pipe jacking vertically crossing under the road, the rectangular pipe jacking of Fuquan Road runs horizontally under the road. At the same time, Fuquan Road is located in the main road of Changning District in the center of Shanghai, and the traffic and pedestrian flows are large, which makes the road settlement strictly required in the construction process of rectangular pipe jacking. In order to effectively control the road settlement, the technical measures such as cylinder pull-back devices, new anti-reverse devices and automatic soil and water compensation devices are adopted. And finally combined with the real-time data statistics of the road settlement monitoring by the third-party monitoring unit, the road settlement of Fuquan Road is controlled within 10mm.
