CORE MATERIAL AND SOIL CEMENT CONTINUOUS WALL CONSTRUCTION METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2014177827
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a construction method of a soil cement continuous wall and a core material used therefor, capable of erecting the core material, capable of improving an insertion property of the core material, capable of also securing erection accuracy and hole drilling accuracy of the core material even when constituted in this way, capable of further shortening a construction period, capable of reducing a frequency of jointly using a vibration hammer, and capable of construction of taking into consideration a neighbourhood environment.SOLUTION: A foundation is excavated by a multiple spindle kneading auger machine, and a continuous integral wall body is established by successively lapping an element of continuing an excavation round hole of containing a mixture of a consolidation liquid and excavation sediment in a state of being tied in a row in the foundation, or the foundation is excavated by a chain saw type cutter post connected to a base machine, and excavation of a groove and injection of a solidification liquid, mixing and agitation with in-site soil are executed by moving in the lateral direction, and when executing soil cement continuous wall construction for establishing a soil cement wall of continuing in the ground, H-shaped steel being a stress burden material (a core material) inserted into the excavation round hole of the element is installed by successively diametrically reducing a flange width so as to taper off toward the tip.
