Jacking-pulling Construction Technology for Underground Box Culvert in Complex Environment and the Application

Abstract:

Combined with an engineering example of Shanghai rail transit line 2, the paper introduces a new jackingpulling technology for underground box culvert, which has advantages of convenient working in narrow area and light environmental impact with high guiding accuracy. This technology is an innovation and supplement to modern pipe jacking construction and a new technical means to underground box culvert construction by trenchless technology and provides solution to development and utilization of underground space in complex environment.
