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,管道兩端砌筑磚堵、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。

Back covered porous brick has been developed in the late period of 1990 ' s , and is produced by semi - dry - pressing method . it has such many advantages as high production efficiency , energy saving , high density , beautiful appearance , high strength , easy bricklaying , and can save 1 / 3 masonry mortar compared with solid brick 盲孔多孔磚是20世紀90年代后期研制成功的、用半干壓法壓制成型的封底多孔磚,它生產效率高,節約能耗,產品致密,外形好,強度高,易砌筑,用于砌體工程時,可節約1 3砂漿。
