CHIPPING DEVICE
PROBLEM TO BE SOLVED: To provide a chipping device capable of chipping a joint surface of a preceding element to impart high waterproof property thereto in constructing an underground wall-like structure even when a joint section between the preceding element and a subsequent element is positioned beneath an underground obstacle.SOLUTION: A chipping device 1 comprises a chipping mechanism 2 to chip a joint surface of a preceding element 10 and a support frame to support the chipping mechanism 2. The support frame has a main frame 4 and a turning arm 3 outwardly extended from the main frame 4 with a base end thereof connected to a lower section of the main frame 4 through a turning axis 32 in a manner that can turn in a vertical direction. The chipping mechanism 2 is attached to a tip section of the turning arm 3.SELECTED DRAWING: Figure 3
【課題】地中に壁状構造物を構築するにあたり、先行エレメントと後行エレメントの打継部が地中障害物の下方に位置する場合にも、先行エレメントの打継面に目荒らしによる高い止水性能を付与することの可能な目荒らし装置を提供する。【解決手段】目荒らし装置１に、先行エレメント１０の打継面を目荒らしする目荒らし機構２と、該目荒らし機構２を支持する支持フレームとを備えてなり、支持フレームは、本体フレーム４と、本体フレーム４より外方に張り出すよう、本体フレーム４の下部に回動軸３２を介して鉛直方向に回動自在に基端部を連結された回動アーム３とを備え、該回動アーム３の先端部に、前記目荒らし機構２が設置される。【選択図】図３
