Abstract
The invention discloses a kind of job practices of mud anti-seepage underground diaphragm wall.This method is applicable to the underground engineering construction of deep excavation, high water level.Concrete grammar is the periphery in underground construction, excavates out closed trenches one, adds mud then in groove, quiet the stopping through 2-8 days, therefore mud form the anti-seepage underground diaphragm wall of flexible together and weak water permeability, and its impervious coefficient is 1-8m/d, can the fine needs that satisfy general underground engineering construction.
Description
The present invention relates to a kind of construction foundation working method that stops the underground water circulation, particularly a kind of mud anti-seepage underground diaphragm wall that is applicable to high water level, deep excavation project.
The practice of existing anti-seepage underground diaphragm wall is: excavate out a long and narrow deep trouth on ground along the periphery of need open excavation with plant equipment, put into reinforcing bar in the groove, penetration concrete then, build up one section reinforced concrete wall, carry out so piecemeal, and every section body of wall is linked to each other with certain joint style, form continuous steel concrete anti-seepage underground diaphragm wall one.This impervious diaphragm wall that is built up by steel concrete, its impervious effect is fine.But this wall of constructing needs higher technology, more plant equipment, complex process, cost height.
Purpose of the present invention is exactly that the mud anti-seepage underground diaphragm wall that a kind of cheap, technology is simple, be applicable to high water level, deep excavation project will be provided.
The present invention is achieved in that the periphery along deep excavation project, excavates out long and narrow closed trenches one on ground, adds in the digging time groove by water, swell soil and or the mud formed of clay.Mud can play the protection cell wall, prevent the effect of caving in the grooving process.Groove construction finishes, and allows mud in groove the quiet 2-8 of stopping days, slurry curing and form the anti-seepage underground diaphragm wall of one flexibility, weak water permeability.The content of swell soil and/or clay is generally the 15-40% of mud total weight in the mud.The transmission coefficient of this wall is 1-8m/d.The excavation width of groove should be determined according to geological condition, is generally 150mm-1000mm, and cutting depth should enter the rock stratum or more than the aquitard 50mm.
Method of the present invention, technology is simple, and the duration is short, and its cost only is equivalent to about 1/3 of concrete anti-seepage underground diaphragm wall, and technical performance can finely satisfy general underground engineering construction needs.
Claims (1)
1, a kind of job practices of anti-seepage underground diaphragm wall, it is characterized in that: the groove that excavates a closure on ground, add the mud of forming by water, swell soil and/or clay in the groove, through quiet stopping 2-8 days, slurry curing forms the anti-seepage underground diaphragm wall of flexible weak water permeability, the content of swell soil and/or clay accounts for the 15-40% of mud total weight in the mud, and the excavation width of groove is 150mm-1000mm, and cutting depth should enter the rock stratum or more than the aquitard 50mm.
