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 technology, the enhancement of construction equipment capacity and the development of pipe manufacturing technology, the application of non-digging pipe pulling technology is more and more widely. According to the engineering example, according to the topography, geomorphology, geology and river hydrology, the design and calculation of pipe and pipe, depth of cover, traverse path, back drag force, drilling equipment, reaming and site layout are emphasized. The design and application of pipe technology in the sewage pipe crossing the river for reference by relevant personnel.
