摘　　要：宝鸡峡漆水河倒虹改建工程U型渡槽之间安装可卸式止水带,通常采用在槽身钢筋上固定预埋件的方法,此方法工作量大且难以保证位置精度,影响止水带的安装质量,易造成渗水现象;本文设计了一种预埋件固定安装定位装置,并详细阐述了固定装置的安装方法,解决了以上施工难题,为类似工程提供一定的借鉴价值。The detachable waterstop is installed between the U-shaped aqueduct of the Baojixia Qishuihe inverted rainbow reconstruction project. Usually, the method of fixing the embedded parts on the steel bar of the trough is used. This method has a large workload and it is difficult to ensure the position accuracy, which affects the installation quality of the waterstop and is easy to cause water leakage. This paper designs a fixed installation and positioning device for embedded parts, and elaborate on the installation method of the fixed device, which solves the above construction problems and provides a certain reference value for similar projects.
