Urban Curved Jacking Pipe Construction Survey Control
Based on the survey control procedure of underground curved pipe jacking project in Qinghefang Street, Hangzhou, this paper concludes the engineering survey control methods applied in urban underground curved pipe jacking process. Since straight-line surveying can be better controlled than curved surveying, this paper introduces a method to transfer the calculation of curved line problem into straight-line problem. In the project we use jacking pit as surveying zero point to perform coordinate transformation through indoor calculation. The jacking forward survey control, control point transfer surveying, during jacking survey control and urban underground curved jacking pipe survey control standard is detailed analyzed and discussed in the paper. The survey control accuracy assurance and error causes are also analyzed; several useful conclusions are made for similar projects.
