Abstract

PURPOSE: To improve the quality of the ground and thereby to prevent risings of the ground over the adjacent zone by putting a casing into the weak ground, kneading the weak ground in the casing together with an improver and then withdrawing the casing.
CONSTITUTION: A bottomless hollow casing 1 is put into weak ground 2 by its own weight or vibration caused by any vibrating means. The pouring tube 4 of a filler means 3 is inserted into the ground within the casing and then drawn out pouring an improving agent such as sand, cement and a mixture thereof. Then the ground 5 and the improving agent 6 are kneaded and mixed with each other by the wings 7 of a kneader 8. Finally the casing 1 is drawn out of the ground 2. The improving agent 6 absorbs water to convert the weak ground into an improved one with the ground particles as a backbone. Thus improved ground will not rise irregularly over the adjacent zone.
