过河污水管道采用非开挖拉管技术的设计

Design and Application of Trenchless Technology to Municipal Sewage Pipeline Crossing River

近年来,随着施工技术水平的提高、施工设备能力的增强以及管材制作工艺的发展,非开挖拉管技术的应用越来越广泛。结合工程实例,根据地形、地貌、地质以及河流水文等情况,着重地对管道管材、覆盖深度、穿越轨迹、回拖力、钻机设备、扩孔、场地布置进行设计与计算,介绍非开挖拉管技术在污水管道穿越河流时的设计应用,供相关人员参考借鉴。

In recent years, with the improvement of construction technologies, enhancement of construction equipment capacities and development of pipe manufacturing process, trenchless technology has been applied more and more widely. Combined with the engineering example, according to the topog- raphy, geomorphology, geology and river hydrology, the pipe materials, cover depth, crossing path, pul- ling force, drilling equipment, bore reaming and site layout were designed and calculated. The design and application of trenchless technology to municipal sewage pipeline crossing river were introduced to provide the reference for the related personnel.
