在民用及工业生产中,各种用途的大型混凝土水池很多。水池混凝土施工完毕,必须不渗不漏,试水合格。如果发生局部渗漏现象,采用带水修堵方法,既可避免将水放进排出的重复作业,缩短工期,又可降低施工费用,节约水源。我们在几个大型钢筋混凝土水池的施工中,成功地进行了带水修堵渗漏工作,我们的做法与有关施工手册介绍的有所不同,现结合施工叙述如下: 1 水玻璃促凝剂的配制目前,水玻璃促凝剂的配方有多种,但有的配方配制的促凝剂与水泥拌合后,需凝结时
In civil and industrial production, there are many large concrete pools for various purposes. After the construction of the pool concrete is completed, it must be leak-proof and the test water is qualified. If partial leakage occurs, the use of a water-removing plugging method can avoid repeated operations of putting water into the discharge, shorten the construction period, reduce construction costs, and save water. In the construction of several large-scale reinforced concrete pools, we successfully carried out the work of repairing and leaking with water. Our approach is different from that described in the relevant construction manuals. Now the combined construction is described as follows: 1 The water glass coagulant Formulation At present, there are many formulas for the preparation of water glass coagulant, but some formulas for the preparation of coagulant and cement need to be condensed after mixing.
