ENVIRONMENTALLY-CONSIDERATE PILE HEAD PROCESSING METHOD
PROBLEM TO BE SOLVED: To provide pile head processing method to be performed in a safe work environment, the processing method being capable of enhancing work precision and reduce labor, at the same time reducing noise, vibration, dust, and exhaust gas discharge generated during the pile head processing work.SOLUTION: A pile head processing method enables reduction of noise, vibration, dust, and exhaust gas, mitigates environmental contamination from work, and reduces labor for workers, and is performed by using mainly electrically- and hydraulically-driven machines, in the following steps for: attaching an edge isolating member 15 for protection and curing and a marking member 20 that serve as marks in excavation work, and constructing a cast-in-place pile, the edge isolating member and the marking member being useful in work that follows for quickly and easily exposing excess concrete 34, without damaging a main reinforcement 5 of the cast-in-place pile; performing a survey so as to enable forming of a cut groove 47 and an appropriate number of drilled hole spaces 56 along entire circumference of the pile, without interfering with the main reinforcement 5; installing a crushed material and a crushing tool 54 in the hole; forming a fracture surface 69 along the cut groove 47; and removing the excess concrete 34 in a lump.SELECTED DRAWING: Figure 1
【課題】杭頭処理作業に於いて発生する、騒音・振動・粉塵・排気ガス排出を抑制し、施工精度の向上と労力の軽減を可能とし、安全な環境で行う杭頭処理作業を提供する。【解決の手段】掘削作業の目印となる、保護養生縁切り材１５、マーキング部材２０を取り付け、場所打ち杭造成後、目印部材の効果により杭構成の主筋５を損傷させること無く余盛コンクリート３４の露呈作業を軽易に行い、探査により主筋５に干渉せず杭全周に切断溝４７及び適当数量の穿穴空間５６を施し、その穴内に破砕材・破砕工具５４を設置し、切断溝４７に沿って破断面６９を形成し、余盛コンクリート３４を塊状で除去する。作業に際しては電力・油圧機材を主として使用することにより、騒音・振動・粉塵・排気ガスを抑え、作業公害・環境公害に対処し、且労働者の労力軽減を可能とした杭頭処理工法。【選択図】図１
