CONNECTION STRUCTURE BETWEEN BUCKET AND CONNECTION CASING, AND EXCAVATED HOLE BACKFILL METHOD
PROBLEM TO BE SOLVED: To provide a connection structure between a bucket and a connection casing, along with an excavated hole backfill method, the bucket being capable of removing residual soil from the excavated hole.SOLUTION: A connection structure comprises a first connection structural body 21 fixed on a bucket 1 and a second connection structural body 31 fixed on a connection casing 10. The bucket includes a peripheral surface part 2 and a bottom surface part 3 provided on an edge side in an axial direction of the peripheral surface part and having an intake port for taking in sediment. The first connection structural body 21 is fixed on the other edge side in the axial direction of the peripheral surface part 2, while the second connection structural body 31 is fixed on an edge side in an axial direction of the connection casing 10. Either the first connection structural body 21 or the second connection structural body 31 is fitted inside the other. On an outer peripheral surface of the either the first or the second connection structural body fitted inside has a protrusion 32 protruding outward fixed at a plurality of locations in a circumferential direction, while an insertion part 22 into which the protrusion 32 is inserted is formed at a location corresponding to the protrusion 32 on the other. A stopper 40 is inserted between the insertion part 22 and the protrusion 32.SELECTED DRAWING: Figure 2
【課題】残留土を掘削穴から取り除くことができるバケットと接続用ケーシングとの接続構造及び掘削穴埋め戻し工法を提供する。【解決手段】バケット１に固定された第１接続構造体２１及び接続用ケーシング１０に固定された第２接続構造体３１で構成され、バケットは、周面部２及び軸方向の一端側に設けられ、土砂を取り込む取り込み口を備えた底面部３を有し、第１接続構造体２１は、周面部２の軸方向の他端側に固定され、第２接続構造体３１は接続用ケーシング１０の軸方向の一端側に固定され、第１接続構造体２１及び第２接続構造体３１の一方が他方の内部にはめ込まれ、これらの一方の外周面には、外側に突出した突起体３２が周方向の複数の位置に固定され、他方には突起体３２に対応する位置に、突起体３２を挿入させる被挿入部２２が形成され、被挿入部２２と突起体３２との間に挿入されるストッパー４０が設けられている。【選択図】図２
