Abstract

PURPOSE: To improve weak ground to ground of high strength by applying compound piling method of driving quicklime piles after driving in such material as earth and sand in the form of pile into ground.
CONSTITUTION: Firstly, to supplement the short of inorganic earth grain which is peculiar to specially weak ground 1, substance such as earth and sand equivalent to that unsatisfactory earth grain, for example, clayey soil, dried soil, lime etc. or one of the inorganic industrial scraps, or compound of not less than two of above substances shall be driven in the extra-weak ground 1 at optional interval and depth with usual equipment forming piles 2, and then, namely after compressed sinking due to water suction of piles 2 is finished, as the second step, quicklime piles 3 shall be driven in at about intermediate positions of above stated piles of earth and sand, etc. in similar depth, and shall be quickly compressed. Thus, improving ground eliminating peculiar property as weak ground is completed.
