隧洞内大尺寸管道运输车

Vehicles for transporting large - diameter tube in tunnel

隧洞内安装大口径埋置式PCCP管道在我国还是首次,由于受空间条件限制,需使用特殊的施工车辆完成其运输和对接安装。目前可供选择的方案一是国外使用较多的驮梁式运管车,另一种是底承式运管车。文章就这两类设备进行了介绍和比较,并着重推荐了底承式运管车。

It is the first time in China for the PCCP tube with large diameter to be installed in tunnel. Special vehicles are necessary to carry out transport and butting due to spacial limitation. There are two schemes to be chosen, one is transport vehicle with packing beam, which is very popular worldwide, the other is the transport vehicle. In this paper a comparison is made for this two schemes and the latter one is recommended.
