- 鄯善-乌鲁木齐输气管道工程达圾城白杨河穿越施工中，首次采用开挖与管沟垂直的T形明沟、利用河床自然高差疏导汇集并排出管沟内积水的方法，不使用-台排水设备，完成了管道和通讯光缆的直埋敷设，为西北地区同类河流的管道穿越施工积累了成功的经验。
A method of digging T section type of drainage ditch vertitx'l tt the direction of pipeline us ing river bed natural altitude to converge and drain water in the pipeline dicth is first used in crossing Baiyang river of San-Wu pipeline project near Da Ban Cheng iIl Xin Jiang province.
