旋挖干作业成孔在城区中风化岩层中的应用

Application of Borehole Drilling in Weathered Rock Stratum in Urban Area

目前,随着国内市政工程的建设发展的趋势和环保要求提高,在市政工程中如何加快施工进度,确保施工质量,减少环境影响是施工企业需要思考的问题。以在城市高架桥桩基工程中,针对中风化岩层地区采用旋挖干作业成孔,解决泥浆的储运等问题,可为类似工程的施工提供借鉴。

With the development trend and environmental protection requirement of municipal engineering,how to speed up construction progress,ensure construction quality and reduce environmental impact in municipal engineering is a problem that construction enterprises need to think about.In this paper,in the project of the pile foundation of the urban viaduct,the problem of mud storage and transportation is solved by using rotary digging and drying in the middle weathered rock stratum.It can be used for reference for the construction of similar projects.
