PILE HEAD PROCESSING APPARATUS
To improve efficiency in installing a concrete pile.SOLUTION: A pile head processing apparatus 10 removes excess concrete on the pile head part of a cast-in-place concrete pile before hardening, the pile head processing apparatus 10 including a weight column 11 that is hung within and inserted into a surface layer casing F provided in a pile hole, and a removal bucket 20 installed on the lower end of the weight column 11. The removal bucket 20 includes a bucket body 20a composed of a conic plate 21 which slopes upward from the center part toward the periphery, and a ring plate 22. A centering tool 40 is installed movably on the weight column 11, and the centering tool 40 engages with the surface layer casing F to position the weight column 11 at the center part of the pile hole. The removal bucket 20 is pressed against excess concrete due to a load of the weight column 11.SELECTED DRAWING: Figure 2
【課題】コンクリート杭の打設効率を向上させる。【解決手段】場所打ちコンクリート杭の杭頭部の余盛を硬化前に除去する杭頭処理装置１０は、杭孔に設けられた表層ケーシングＦの内部に吊り下げられて挿入される重り支柱１１と、重り支柱１１の下端に装着される除去バケット２０とを有する。除去バケット２０は、中心部から外周部に向けて上方に傾斜した円錐板２１と環状板２２からなるバケット本体２０ａを備えている。重り支柱１１には芯出し具４０が移動自在に装着され、芯出し具４０は表層ケーシングＦに係合して重り支柱１１を杭孔の中心部に位置決めする。重り支柱１１の荷重により除去バケット２０は余盛に押し込まれる。【選択図】図２
