測壓管法
英文
manometer method-
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
閉水試驗方法因其應用時間較長，目前已積累了較豐富的經驗，但在閉水試驗時，管道兩端砌築磚堵、抹防水層、養護、灌水浸泡，以及試驗后的放水、磚堵拆除等繁雜工序，不僅費工、費時，而且消耗原材料，尤其是在缺水的地區以及頂管施工的無壓管道，這些矛盾更加突出；因此，為滿足迅速發展的市政建設需要，有必要探索新的檢測方法，閉氣試驗就是其中一種，但是閉氣試驗目前還不完善，有待于進一步深入研究。Measuring methods of the heater or filament current and voltage for electronic tubes
