近年来,山东省渠道衬砌的发展比较迅速,许多新建和扩建的大中型骨干输水工程都采用了混凝土板等衬砌措施,较好地解决了土基渠道渗漏损失大、边坡易坍塌和引黄灌区泥沙淤积等问题。本文结合胜利油田七干渠渠首段衬砌工程的排水试验和应用实践,就高地下水位条件下渠道衬砌的施工排水和防扬压力排水问题进行了总结和分析,以期供类似工程设计时参考。 In recent years, the development of channel lining in Shandong Province has been relatively rapid. Many newly built and expanded large and medium-sized backbone water diversion projects have adopted lining measures such as concrete slabs to better solve the problems of large leakage of earth-based channels, collapsibility of slopes and Sediment deposition in Yellow River Irrigation District and other issues. Based on the drainage test and application practice of lining construction in the first canal of Shengli Oilfield, this paper summarizes and analyzes the construction drainage and anti-Yang pressure drainage of canal lining under high underground water level in order to provide reference for similar engineering design.
