深沟槽PCCP管龙门式起重机安装工法
摘要：
一种深沟槽PCCP管龙门式起重机安装工法，将龙门式起重机横跨沟槽两边和/或设置于沟槽底部，利用龙门式起重机完成PCCP管卸管、就位和/或安装作业。龙门式起重机选自大龙门式起重机、高低跨龙门式起重机和小龙门起重机。适用于沟槽宽度范围为10～30m；沟槽深度范围为8～10m的施工作业。该工法满足应急工期的需要，解决国内大型履带起重设备不足、成本高的现况，提高管道施工安全性。
摘要（英）：

The invention discloses a method for installing PCCPs (prestressed concrete cylinder pipes) in deep grooves by virtue of a gantry crane. The gantry crane stretches across the two sides of a groove and/or is arranged on the bottom of the groove, and is utilized to finish the operation of unloading, location and/or installation of a PCCP pipe. The gantry crane is selected from a large gantry crane, a high-low striding gantry crane and a small gantry crane, and is suitable for field operation with the width range of the groove from 10m to 30m and the depth range of the groove from 8m to 10m. The installation method provided by the invention meets the requirement of an emergency construction period, overcomes the current situation that large-scale crawler hoisting equipment in China is not enough and is high in cost, and can improve the security of the pipeline construction.
