WATER CONDUIT FOR DRIVING METHOD OF PILE USING PRESSURE WATER

摘要

PURPOSE: To promote driving efficiency of a driving pile by forming a water conduit main body of a hose body having movability. ;CONSTITUTION: A water conduit 1 is constituted of water conduit main bodies 2 of hose bodies having movability and connection bodies 3 provided to both ends of the water conduit main bodies 2 and having male screws 3a screwable to water conduit connection devices 4 welded 8 in advance at specific intervals lengthwise of a driving pile 6. After that, the water conduit 1 is so constituted that a mounting position of the water conduit 1 to the driving pile 6 is not always provided on the straight line lengthwise of the driving pile 6, and the water conduit 1 is instantaneously mounted to the driving pile 6 between the connection devices 4 mounted in advance. Then, in the case a plurality of water conduits 1 are connected, welding work of the water conduits 1 or length adjusting work such as cutting, etc., with the connection is not required, and the water conduits 1 are connected respectively to the driving pile 6 instantaneously. According to the constitution, the water conduit 1 is speedily mounted, and driving efficiency of the driving pile 6 can be promoted.;COPYRIGHT: (C)1995,JPO
