重复组装式导流桩坝施工消耗量研究

摘要

This paper analyzed the hydrolofical,meteorolofical and the spot feolofical conditions durinf the process of Outan emerfency repair and based on the observation of the number or amount of personnel,materials and machinery and the work process,made a quantitative analysis of the consumption of personnel,materials and machinery in the construction quota of the re-assembled diversion pile froin. The results show that the cost of the re-assembled pile dam is 128,000 Yuan/100 m,and in the case of sinfle pile lenfth of 20 m,the investment for every 100 extended meters of pile dam will be around 3. 2 million Yuan. Compared with the traditional earth-rock dam emerfency repair,the re-assembled diversion pile dam has showed some advantafes in terms of construction anti-interference,proJect investment and future maintenance,therefore,it has a precondition for popularization and application.%分析了重复组装式导流桩坝在欧坦抢险施工过程中的水文、气象和现场地质条件，结合施工过程中对人员、材料、机械使用数量和工作过程的观测，定量分析了重复组装式导流桩坝施工定额中人员、材料、机械的消耗量。结果表明：重复组装式导流桩的费用为12.8万元/100 m，在单桩长20 m的情况下，每100延米的桩坝投资约为320万元；与传统的土石结构抢险坝相比，重复组装式导流桩坝在施工的抗干扰性、工程投资、日后的管理维护等方面均表现出一定的优势，具备推广应用的前提条件。
