Abstract

PURPOSE:To curtail the cost and period of construction work by repeating a process in which a breaker is positioned at a given depth in the hollow of a hollow concrete pile and unnecessary portion of the pile is broken by the supply of energy from the ground's surface till the uppermost portion of the pile. CONSTITUTION:A breaker 5 is hung down by a wire rope 6 into the hollow 3 of a hollow concrete pile 2 driven into the ground 1 from above to a planned reference line 4 of the head. Pressure oil is supplied from an oil pressure unit 7 on the ground's surface to the oil-pressure operating part of the breaker 5 to operate the chisel 8 of the breaker 5 for breaking the lowermost part 9 of unnecessary portion 10 of the head of the pile 2 from inside. The breaker 5 is then further moved up to the next treating position to break unnecessary portion 10. The process is repeated up to the uppermost portion 11 of the pile head. Since the pile can be treated at the same time as excavation is progressed, the construction period can be shortened.

Effects of the Invention The first invention crushes piles buried in the ground from the inside, so there is no need to excavate to expose the next pile head each time the pile head is crushed, and it is difficult to do so during excavation. Since there are no obstacles, excavation is easy, and because the processing of thick materials can be done at the same time as excavation, the construction period can be shortened and construction costs can be reduced.

The third invention is that it is possible to crush a buried hollow concrete pile by powerfully applying a chisel using hydraulic pressure from inside the hollow hole, and in addition, pressure oil is distributed evenly from the hydraulic oil tank to each cylinder. Since the force is distributed evenly to the expansion and contraction of the piston, it is suitable for efficiently breaking cylindrical objects. Furthermore, since it uses a single-acting ram, the number of hydraulic hoses is small, making it easy to break. The structure of the device can be made compact, making it effective as a device that can be used directly to treat hollow concrete pile pile heads.
