人工挖孔灌注桩开挖岩层费用的计算方法

COST CALCULATION OF ROCK EXCAVATION FOR HAND DUG CAST-IN-SITU PILE

针对陕西省建筑工程费用计算用现行定额《陕西省建筑、装饰工程消耗量定额》(陕西省建设厅2004年)人工挖孔灌注桩子目中缺乏人工开挖岩层相关子目的情况,笔者结合工作经验,提出了几种人工挖孔灌注桩施工时开挖岩层费用的计算方法。

Current ratings for calculation engineering cost in Shaanxi Province are based on the ＂Building, decoration engineering consumption quota＂ in Shaanxi Province that was issued by Shaanxi Bureau of Construction in 2004, in which some sub-items relevant to hand excavation of rock layers are not included in the items of hand dug cast-in-situ pile. Combining with the writer＇ s experiences, some calculation methods for the cost of hand excavation of rock layers in hand dug cast-in-situ pile engineering are provided for reference.
