摘要:: 本文报道管道穿越埋深3.5～5m、大于5m和小于3.5m的三类坎儿井的施工方法，为新疆地区的管道建设工程提供了成功经验。
Oil pipeline constructed in Xinjiang area will cross the special underwater delivery installa-dons under the name of Kan Er Well’.Kan Er Well can be divided into 3 types:i. e. more than5m,less than 3. 5m and 3. 5m~5m according to the buried depth. The Kan Er Well crossing ofKu Erle to shanshan oil pipeline is successfully carried out by means of lintel protection (i. e. bytaking the concrete pipe which is upper bend and square-shaped as cross一over water pipe)andchanging mechnical operation into the labour operation,Therefore experiences for constructing oilpipeline in Xinjiang area are accummulated. (Note①:Kan Er Well-An irrigation system of wells connected by underground Channels used in Xinjiang area.)
