水磨钻成孔施工定额测定及单价分析

Quota Determination and Uint Price of Water of Wate Mill Drilling

受既有构筑物、施工现场地形地貌及施工本身的技术条件等因素的影响,常规钻孔桩或人工(爆破)挖孔桩难以施工,可采用水磨钻人工挖孔施工,确保工程能够顺利实施。现行铁路工程预算中未有水磨钻成孔相关定额,以贵南高铁为依托,采用写实记录法测定了水磨钻成孔的工料机消耗,并对其进行了单价分析。

Affected by the existing structures, the topography of the construction site and the technical conditions of the construction, the drilled piles or artificial(blasting) dug piles are can’t be applied. Then water mill drilling can be applied to ensure the smooth implementation of the project. The current railway project budget quota doesn’t contains the quota of water mill drilling.This paper determinates the consumption of artificial, material and machinery, and analyzed the unit price relying on the guiyan-nanning high-speed railway.
