摘要
铁路增建Ⅱ线锚固桩施工紧邻既有线,采用传统的钻爆法施工工艺易受"天窗"点施工的影响,人员和机械设备的施工效率大大降低,且安全风险高,成本较大。此文通过襄渝Ⅱ线锚固桩水磨钻施工工艺的经济技术分析,得出水磨钻的成本和定额基价。经过与传统钻爆法进行比较,显示出水磨钻施工工艺具有安全、经济、实用等特点,具有较好的推广利用价值。
The fact that construction points of anchor piles of added second railway line near the existing railway lines defies traditional drilling and blasting method which is easily affected by skylight -point construction and is characteristic of little efficiency, high risk and large cost. This paper calculates cost of water grinding and its quota price via the economic and technical analysis of water grinding construction technology in added second railway line of Chengyu line. Besides, it also finds out that water grinding construction technology has following characteristics ： safe, economic, useful as well as good popularization＆utility value.
