闭气
water tight
biqi闭气(water tight)在堵口工程合龙后,采取阻水断流措施,阻止缝隙漏水。 用立堵法合龙,当合龙绿尚未蛰实,坝身仍然漏水,坝后翻花不止,大小远近不一,应辨明是底漏还是腰漏,如是底漏,说明绿体尚未到底,比较严重。闭气方法,一般有:①在正坝堵合后,除合龙蹄上加压土外,于口门坝前加修绿工,称为关门端。然后抛袋土及加修土俄,使之闭气;②双坝合龙时,用边坝合龙闭气,在正坝与边坝之间,用袋土及粘土填筑土柜,边坝之后再加后战,阻止透水;③修筑养水盆,即在坝后修筑围堤一道,把门口冲深的潭坑围起来,用以积蓄坝后渗水,抬高坝后水位与大河相平,即可闭气。对平堵的口门,因抛石渗漏严重,须采用①、②两种闭气办法,截堵渗流。(徐福龄)
