狭窄地段的PCCP管道安装

The Installation of PCCP Pipes in A Narrow Zone

在PCCP管道安装施工中,需根据实际施工条件,合理选择吊装方法,以提高工作效率。文中主要介绍了万家寨引黄工程联接段PCCP输水工程中采用自制人字抱杆,解决个别地段因地形限制而不能采用大吨位吊车进行PCCP管道吊装的施工方法。

In the construction and installation of PCCP pipes, the main problems needed to be solved are lifting and installing. In order to improve the efficiency, choosing a rational method based on the practical situation is necessary. In the paper, a self-made A-framed derrick used in the PCCP engineering of the connection works, Wanjiazhai YRDP is introduced. This solves the restriction of certain region in which construction methods of using cranes erecting by overhanging PCCP pipe are impossible.
