It is constituted with dirty sewage channel , shawan river brake , shawan river repairing , yanfang road peak pipe , in which sewage channel arises from shawan river and ends at liantang river with total length of 7075m and planned total investment of 400 million rmb 由污水通道、沙湾河水闸、沙湾河整治、延芳路顶管组成，其中，污水通道起于沙湾河，终点至莲塘河，全长7075米，计划总投资4亿元。
Finally , an example of circular jacking pipe constructed by smw method was analyzed , cws ' s specificity of material zoning in circular direction was clarified . the paper ' s main research findings are to propose ring - beam load - distribution theory provide cws ' s calculation method and program software 最后，对一个用smw工法建造的圆形顶管工作井工程实例进行了分析，阐明了沿环向材料分区时的工作井的一些特殊特征。
By analysis the results of in - situ monitoring in the process of pipe jacking , the law of surface deformation perpendicular to pipe axis and along pipe axis , the sub - surface movements perpendicular to the axis of pipe and along the axis of pipe are studied 通过对顶管工程现场测试数据的分析，研究了顶管施工引起的管道周围土体的移动规律，包括地面横截面和纵向截面变形规律、深层土体沿管道轴线方向和垂直于管壁方向移动规律。
