Experimental Study On Technique Of Seepage Control Of Levee And Dam

Many dams and levees need seepage treatment in our country. In recent years, many new techniques of seepage control of levee and dam have been studied which are suit for Chinese condition, but each new technique has its advantage and disadvantage and limitations. There is no precedent that high-pressure jet grouting and mould vibrosinging of impervious panel walls are comprehensively applied in one project. Combining underground dam construction of Wang River in LaiZhou, this dissertation experiments and studies comprehensive application of these two techniques, expounds and proves the possibility and reasonability of comprehensive application, and sets up relevant construction technology and parameter.This dissertation including three parts:Part one reviews and summarizes the general conditions of development and present conditions of operation of levee and dam in our country, discusses the principles, advantages and disadvantages as well as flexibilities of present seepage control of levee and dam.Combining underground dam construction of Wang River in LaiZhou, part tow experiments and studies comprehensive application of high-pressure jet grouting and mould vibrosinging of impervious panel walls, discusses experimental course and construction technology of single pore and shallow continuous walls of high-pressure jet grouting, mould vibrosinging of impervious panel walls, combined walls of high jet and mould vibrosinging , as well as combined surrounding well.Part three analyzes experimental results. By excavating check, pumping experiment, indoors experiment, it is proved that every checked and measured index of seepage control body of high jet combined mould vibrosinking reaches designed requirement, and by analysis of work efficiency and economy , it is also proved that combination of both sides is higher work efficiency, lower investment than high-pressure jet technology.
