PROCESS FOR CONSTRUCTING CONTINUOUS WALL OF DAM UNDER GROUND AND APPARATUS FOR THE SAME

摘要

PURPOSE: A process and an apparatus for forming a continuous wall of dam under ground are provided to make digged earth and cement adhesive uniformly admixed and rapidly solidified and cured by utilizing a rotator provided with rotating power from auger machine. CONSTITUTION: The apparatus comprises an auger machine(16), a rotator(2) to receive rotating power from the auger machine, a number of connection rods(3), agitation rods(4) and excavation rods(5) in order at an output axis of the rotator, single swivels mounted on the auger machine and the rotator, and a cement adhesive supplying line attached to each of the rods and another combined swivel(6) located at the output axis of the rotator to furnish pneumatic pressure and chemicals at the same time. By such construction of the apparatus, the excavation rod(5) having a number of excavation bits at equal space outputs the cement adhesive and the pneumatic pressure to form the continuous wall of a dam.
