在立井设计施工中要解决的一个关键问题就是井壁渗水问题。根据我国多年来建井的经验,找到立井井壁渗水的途径,分析了立井井壁产生裂缝以及井壁接茬发生渗水的原因,并提出有效可行的办法。高抗渗混凝土的配制解决了井壁本身渗水的问题;通过对井壁接茬的物理、化学处理以及接茬结构的优化设计,可以有效解决接茬渗透问题。
One of the key issues to be solved in the design and construction of vertical shafts is the seepage of borehole wall. According to the experience of our country to build wells over the years, we can find out the ways of water seepage in shaft wall, analyze the causes of cracks in shaft wall and the seepage of shaft wall stubble, and put forward the effective and feasible methods. The preparation of high impervious concrete solves the problem of water seepage in the wall of the well itself. The physical and chemical treatment of the well wall and the optimal design of the stubble structure can effectively solve the problem of the seepage of the stubble.
