滈河倒虹设计全长4．76km，双管布里，安装直径2m承插式预应力钢筋混凝土预制压力管道。针对当地沟深坡陡等实际情况和管道安装要求，我们研制一套由带有行走部份的钢结构龙门吊架轨道和牵引设备，解决了大口径大重量管道陡坡段的运输及安装问题。
Bahe inverted siphon design a total length of 4.76km, double pipe, installation diameter 2m socket type prestressed concrete prefabricated pressure pipe. In view of the actual conditions such as the steep slope in the local ditch and the pipeline installation requirements, we have developed a set of steel gantry hanger rails and traction equipment with walking parts to solve the transportation and installation problems of large-diameter and large-weight pipe steep slope sections.
