The method of close water test has been used for a long time , so richer experience has been achieved . however , it not only takes pains and time , but also consumes raw materials during the close water test because of miscellaneous working procedures such as bricklaying in the two ends of pipe , water - repellent layer plastering , maintaining and water offletting , brick - block backouting after the test , especially in the region short of water and some drainage pipe with prop - pipe construction . in order to satisfy the fast development of municipal construction , new detection methods should be developed
闭水试验方法因其应用时间较长，目前已积累了较丰富的经验，但在闭水试验时，管道两端砌筑砖堵、抹防水层、养护、灌水浸泡，以及试验后的放水、砖堵拆除等繁杂工序，不仅费工、费时，而且消耗原材料，尤其是在缺水的地区以及顶管施工的无压管道，这些矛盾更加突出；因此，为满足迅速发展的市政建设需要，有必要探索新的检测方法，闭气试验就是其中一种，但是闭气试验目前还不完善，有待于进一步深入研究。
