本考案は方向切替弁と油圧ピストンの相互作用で該油圧
ピストンを振動せしめる油圧振動弁を用いた油圧振動式
締固め機に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hydraulic vibrating compaction machine using a hydraulic vibrating valve that vibrates a hydraulic piston through interaction between a direction switching valve and a hydraulic piston.
現在、水道管、ガス管などの埋設工事において、埋戻上
の締固めに適した締固め機はない。Currently, there is no compaction machine suitable for compacting backfill in the construction of underground water pipes, gas pipes, etc.
埋設溝は幅が狭く深いため、通常のランフ、振動プレー
トは使用に適さない。The buried trench is narrow and deep, so normal ramps and vibrating plates are not suitable for use.
そのため埋戻しに山砂が用いられ、水棒めがなされてい
るが機械的に充分に締固めていないため、道路の埋設管
などには過大な負荷が加わり漏水、ガス洩れ等の原因と
なっている。For this reason, mountain sand is used for backfilling and water bars are used, but because it is not mechanically compacted sufficiently, excessive loads are placed on buried road pipes, causing water leaks, gas leaks, etc. ing.
また、土取り、土捨ての規制から掘削上を埋戻しに再利
用せざるを得ない社会情勢にあるため、この掘削土を埋

め立上る必要がある；本考案は上記点に鑑みなされたも
ので、埋戻上の締固めに適した大きな締固め力と作業性
、機動性を備えた油圧振動式締固め機を提供するもので
ある。In addition, due to regulations regarding earth removal and soil disposal, we have no choice but to reuse excavated soil for backfilling. It is necessary to stand up for compaction; the present invention was developed in view of the above points, and provides a hydraulic vibratory compaction machine with large compaction force, workability, and maneuverability suitable for compaction on backfill. It is something to do.
以下、本考案の実施例を図によって説明する。Hereinafter, embodiments of the present invention will be described with reference to the drawings.

成される。In the figure, a hydraulic power source 1 is installed on a traveling vehicle 2, a boom 3 that can move vertically and freely is attached to the traveling vehicle 2 via a tilting cylinder 11, and a supporting cylinder 12 is attached to the tip of the boom 3.
A hydraulic cylinder 4 is provided through the hydraulic cylinder 4, and a hydraulic vibration valve 7 is coupled to the rod 15 of the hydraulic cylinder 4 to vibrate the hydraulic piston 6 through interaction between the direction switching valve 5 and the hydraulic piston 6. 8 Compaction plate 9 at the tip
is provided, and the compaction plate 9 is pressed into the ground 10 by the hydraulic cylinder 4.
At the same time, the hydraulic vibrating valve 7 is made to oscillate, and the compaction plate 9 repeatedly hits and compacts the ground 10.

結合した締固め板９で地面１０を打撃締固める。A buried trench 14 in which a buried pipe 13 is installed for the traveling vehicle 2 having the above configuration.
The compaction plate 9 is pressurized by the hydraulic cylinder 4 in the ground 10 on the backfill of a required thickness, and the hydraulic pressure from the hydraulic source 1 is supplied to the hydraulic vibrating valve 7 to cause it to oscillate, which is connected to the hydraulic piston 6. The ground 10 is compacted by impact with the compaction board 9.
