长距离混凝土输水管道水压试验若干问题的探讨

Discussion on Water Pressure Testing of Concrete Pipeline for Long Distance Water Conveyance

水压试验是压力管道竣工验收之前必须履行的一个试验项目。对长距离混凝土输水管道水压试验过程中遇到的具体问题———“渗水”与“漏水”现象的划分界线、“保持恒压”的实施办法、相邻试压段之间连接段管道的试压办法以及严密性试验时降压 0 1MPa所经过的时间t1的测定等 ,结合运城地区引黄济运供水工程的实际 。

Water pressure testing is indispensable before the final completion and acceptance of pressure pipeline construction. Some common problems in pressure testing are described including the discrimination of seepage and leakage , persistent preservation of constant pressure, testing of connective pipe of two adjacent sections and t 1 (time course of pressure drop 0 1 MPa) examination on the practices of Yellow River Water Diverting Engineering to Yuncheng city, Shanxi Province.
