SEA DEEP CEMENT MIXING METHOD USING DEEP CEMENT MIXING BARGE FOR REINFORCEMENT OF UNDERWATER GROUND

摘要

The present invention relates to a sea deep cement mixing method using a deep cement mixing barge for underwater ground improvement which is carried out anytime without any influence of sea environment like tides and allows a deep cement mixing barge to accurately correspond to a construction line of the underwater ground through GPS measurement, thus conducting rapid construction at an accurate position. According to the present invention, the sea deep cement mixing method includes a first step of locating a deep cement mixing barge for underwater ground improvement at a construction line of the underwater ground; a second step of fixing the deep cement mixing barge at the construction line of the underwater ground; a third step of arranging two or more deep mixing equipment mounted on the deep cement mixing barge fixed to the construction line of the underwater ground in one row on the same line; and a fourth step of allowing the two or more deep mixing equipment arranged in the one row to excavate the underwater ground in the same direction as each other and to mix slurry. On the other hand, the sea deep cement mixing method further includes a fifth step of arranging the deep mixing equipment in another row in the deep cement mixing barge after the fourth step and allowing the deep mixing equipment to excavate the underwater ground in the same direction as each other and to mix slurry; and a sixth step of moving the deep cement mixing barge after the fifth step, locating and fixing the deep cement mixing barge to another construction line and repeatedly conducting the third, fourth and fifth steps to complete the underwater ground improvement.
