チである。[Detailed description of the invention] In this invention, a shank rod 10 is protruded from the tip of a rock drilling machine 1 which is supported so as to be able to rise and fall along an upright guide cell 9, and a drilling rod 4 or a pile 5 is attached to the shaft 10 via an attachment 11. The hollow muffling tube 2 covering the bases of the shank rod 10, the attachment 11, and the drilling rod 4 or the pile 5 is attached to the tip thereof, and an inclined inner circumferential surface 3 is attached to the tip opening of the muffling tube 2. A rubber material 7 having an inclined outer circumferential surface 6 in contact with the inclined inner circumferential surface 3 is fitted to the base of the drilling rod 4 or stake 5, and a band 8 supporting the bottom surface of the rubber material 7 is fitted to the base of the drilling rod 4 or stake 5. The present invention relates to a muffling device that is fitted into a muffling device. Rock drilling machine 1
is a downward rock drilling machine supported by a guide cell 9 upright on the ground so as to be able to move up and down, and repeatedly strikes the shaft 10 with an internal piston to drill the base of the rod 4 or pile 5 through the attachment 11. This is a downward blow. As shown in FIGS. 2 and 3, the muffling cylinder 2 has a lead plate 12 stretched on its inner surface, and rubber plates 13, 13 stretched on its inner and outer surfaces. It is preferable to use a rubber band as the band 8. The attachment 11 has a female screw hole 14, and the shank rod 10 can be screwed into the upper end, and the base end of the rod 4 can be screwed into the lower end, or the base end of the stake 5 can be connected to the lower end. Note that 15 in the figure is a supporting body for the guide cell 9, and 16 is a lifting winch for the pile 5.

て密着する。 Therefore, when the shaft 10 is repeatedly struck by a piston using air or hydraulic pressure, and the base of the rod 4 or the pile 5 is struck downward through the attachment 11, the rod 4 can drill a pile hole. In addition, instead of the rod 4, the H-shaped steel pile 5 can be driven into the pile hole by striking the base of the H-shaped steel pile 5 downward in the same manner as described above. The impact sound caused by the repeated hitting between the piston and the shank rod 10 and the impact sound between the H-shaped steel pile 5 and the attachment 11 enters the silencer cylinder 2, which has the inclined inner circumferential surface 3 and the inclined outer circumferential surface 6 in contact therewith. The rubber material 7 prevents the sound from propagating to the outside of the sound deadening cylinder 2, thereby muffling the sound. The rod 4 or the stake 5 repeatedly moves downward due to the repeated beating, but the band 8 and the rubber material 7 tend to remain stationary due to inertia, and the muffler 2 descends, so the inclined inner circumferential surface 3 and the rubber Slanted outer peripheral surface 6 of material 7
and are in close contact with each other due to the impact vibration of the rod 4 or stake 5.
従来の土留用Ｈ形鋼親杭打設には振動や騒音が
発生し、そのため住民との間にトラブルが生じ市
街地におけるバイブロハンマー等の使用は大型で
あるため困難である欠陥があつた。 The conventional method of driving H-beam steel main piles for earth retaining has the disadvantage that it generates vibration and noise, which causes trouble with residents, and that it is difficult to use vibrohammers etc. in urban areas due to their large size.
本案は上記欠陥に鑑みなされたものであつて、
本案は上述のように構成したので穿岩機１および
穿孔用ロツド４又は杭５による土留用親杭打設に
おいて騒音が発生せず市街地における杭打設作業
を円滑に施工し得る実益がある。 This proposal was made in view of the above defects, and
Since the present invention is constructed as described above, there is a practical benefit in that no noise is generated when driving the earth retaining parent pile using the rock drilling machine 1 and the drilling rod 4 or the pile 5, and the pile driving work in urban areas can be carried out smoothly.

止することができる。 In addition, the vertical accuracy of the parent pile can be maintained, and the rod 4 or the pile 5 repeatedly moves downward due to the repeated hitting impact, but the band 8 and the rubber material 7 do not descend due to inertia and try to stay still, and the sound deadening cylinder 2 As the rubber member 7 descends, the inclined outer circumferential surface 6 of the rubber material 7 comes into close contact with the inclined inner circumferential surface 3 to form a closed chamber, and the band 8 also comes into close contact with the lower surface of the rubber material 7 to support the rubber material 7. The opening at the tip of the muffling cylinder 2 is strongly sealed by the rubber material 7 and the band 8, and the impact noise of the rock drilling machine 1 is sealed in the opening and can be prevented from radiating to the outside.
