PRODUCTION OF GROUTING SOLUTION FOR SOLIDIFYING GROUND, PRODUCING APPARATUS, GROUTING AND GROUTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for producing grouting solution for solidifying ground, capable of preparing plural grouting a solutions and continuously preparing by classifying and fraction ating a suspension containing granules for solidification of ground different in particle diameters into a fine granules-containing suspension and a crude granules-containing suspension and an apparatus for producing the solution. SOLUTION: This method for producing a grouting solution for solidification of ground comprises classifying and fractionating a stock solution suspension containing granules for solidification of ground different in particle diameters into a suspension A containing granules having fine particle diameters and a suspension B containing crude particle diameters, respectively by centrifugal force. The apparatus for producing the grouting solution comprises a preparing tank 2 for stock solution suspension 1 and a granules-classying device 4 connected to the preparing tank 2 and classifying and fractionating respectively the suspension A from the upper part and the suspension B from the lower part by jetting and intorducing the stock solution suspension 1 thereinto. The method for grouting into ground comprises classifying and fractionating the suspension A and the suspension B to prepare plural grouting solutions for solidification of ground and selectively and continuously grouting one or plural kinds of grouting solutions according to conditions of ground to be grouted.
