国内传统的桩头采用人工使用风镐的方法破除,施工期间噪声、振动和粉尘比较大,操作人员的劳动强度高。同时,破除后的桩头部位容易产生微裂缝,桩头表面也不平整,施工速度慢。主要介绍了目前欧洲桩头破除时采用的两种绿色施工技术:机械挤压破碎法和整体截除法。重点阐述了整体截除法之一的Recepieux法的施工工艺。对整体截除法的综合效益进行分析,并提出了在我国的有关实施建议。
The traditional domestic pile head by manual use of picks to get rid of, during construction noise, vibration and dust larger, the operator of high labor intensity. At the same time, the pile head after the rupture prone to micro-cracks, pile head surface is not smooth, slow construction. The paper mainly introduces two kinds of green construction techniques used in the current European pile head breaking: mechanical crushing and crushing method and overall cutting method. The article focuses on the construction of Recepieux method, which is one of the whole truncation methods. Analyzes the overall benefit of the law of total exclusion, and puts forward the relevant implementation suggestions in our country.
