EXCAVATION DEVICE FOR UNDERMINING
PROBLEM TO BE SOLVED: To provide an excavation device for undermining in which the excavated soil produced in the undermining can be crushed to an extent capable of being discharged by a land pump while undermining the lower part of the underground obstacle.SOLUTION: An excavation device includes an excavation mechanism 3 for undermining, a crushing aid 4 for crushing the excavation soil in cooperation with the excavation mechanism 3 for undermining, and a support frame 2 in support of these. The excavation mechanism 3 for undermining comprises a rotary cutter disposed so that the rotating shaft extends in the groove width direction of an excavated groove 10. The support frame 2 comprises a body frame 5 and a turning arm 6 turned in the vertical direction. The excavation mechanism 3 for undermining and the crushing aid 4 are installed in the side becoming the upper surface when the turning arm 6 is overhung from the support frame 2.SELECTED DRAWING: Figure 5
【課題】地中障害物の下方を透かし掘りしつつ、透かし掘りにて発生する掘削残土を、揚泥ポンプにて排土可能な程度に破砕することの可能な透かし掘り用掘削装置を提供する。【解決手段】透かし掘り用掘削機構３と、透かし掘り用掘削機構３と協働して掘削土砂を破砕する破砕補助具４と、これらを支持する支持フレーム２と、を備え、透かし掘り用掘削機構３は、掘削溝１０の溝幅方向に回転軸が延在するよう配置されるロータリーカッタよりなり、支持フレーム２は、本体フレーム５と、鉛直方向に回動する回動アーム６よりなり、回動アーム６が支持フレーム２より張り出した際に上面となる側に、透かし掘り用掘削機構３と破砕補助具４を設置する。【選択図】図５
