SLINGING JIG OF BLOCK AND REMOVAL METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a slinging jig of a block and a removal method thereof, capable of securing safety of work.SOLUTION: A slinging jig 11 of an underwater block is provided for inserting a slinging string-like body 12 under the underwater block and hooking this slinging string-like body 12 on a lower part of the underwater block. The slinging jig comprises: a preceding string-like body 13 thinner than the slinging string-like body 12, for inserting the slinging string-like body 12 under the underwater block; a sheath pipe 14 through which this preceding string-like body 13 is inserted; and a floating body 15 provided on the tip of the preceding string-like body 13 inserted through this sheath pipe 14. The floating body 15 and the tip of the sheath pipe 14 are inserted under the underwater block from one side of the underwater block, and when the floating body 15 floats up on the other side, the sheath pipe 14 is extracted to one side. The slinging string-like body 12 is connected to the base end of the preceding string-like body 13, the slinging string-like body 12 is inserted under the underwater block by puling the preceding sting-like body 13 to the other side, and the slinging string-like body 12 can be hooked on the lower part of the underwater block.SELECTED DRAWING: Figure 1
【課題】作業の安全性を確保することができるブロックの玉掛用治具とその撤去方法を提供する。【解決手段】水中ブロックの下方に玉掛用紐状体１２を挿通し、この玉掛用紐状体１２を水中ブロックの下部に掛ける水中ブロックの玉掛用治具１１である。玉掛用紐状体１２より細く該玉掛用紐状体１２を水中ブロックの下方に通すための先行用紐状体１３と、この先行用紐状体１３が挿通される鞘管１４と、この鞘管１４に挿通した先行用紐状体１３の先端に設けた浮体１５とを備える。水中ブロックの一側から浮体１５と鞘管１４の先端を水中ブロックの下方に挿入し、浮体１５が他側に浮き上がったら、鞘管１４を一側に引き抜き、先行用紐状体１３の基端に玉掛用紐状体１２を連結し、先行用紐状体１３を他側に引っ張って玉掛用紐状体１２を水中ブロックの下方に挿通し、水中ブロックの下部に玉掛用紐状体１２を掛けることができる。【選択図】図１
