我队自1980年以来,在冶金企业地下构筑物漏水漏油的防堵工作方面积累了一定的施工经验。在工作中我们的体会是:冶金企业的电缆隧道、地下生产线等漏水,应以堵为主、排为辅,堵排结合。而地下主电室、风机室、油库等漏水漏油,则应以“堵”为唯一施工方案。经过几年的施工实践,在自制出能带水作业快速凝固的MJ-1剂的有利条件下,筛选出防止水、油(汽油、柴油、润滑油等矿物油)渗漏的施工配方,现介绍如下。一、准备工作 1.先将渗漏处混凝土面的杂质、油垢、
Since 1980, our team has accumulated certain construction experience in preventing the leakage of oil leaking from underground structures of metallurgical enterprises. In our work, our experience is: leakage of cable tunnels and underground production lines of metallurgical enterprises should be mainly based on blockage, supplemented by platoons, and combined with blocking and platooning. Whereas leakage of oil leaks from underground main power rooms, fan rooms, oil depots, etc., “blocking” is the only construction plan. After several years of construction practice, under the favorable conditions of self-manufactured MJ-1 agent capable of rapid solidification with water, a construction formula for preventing leakage of water, oil (petroleum, diesel oil, lubricating oil and other mineral oils) was screened out. Introduced as follows. First, the preparation 1. First, the leakage of concrete surface impurities, grease,
