长江口岸粉细砂拉森钢板桩围堰技术研究

Study on Larssen Steel Sheet Pile Cofferdam Technology in Silty Fine Sand at Changjiang Port

改革开放以后,我国国民经济快速发展,国家的基础设施建设也是遍地开花,尤其随着城市圈的不断扩大,城市内为了节约用地,多以桥梁形式进行道路建设。因此,本文依托庐铜项目站前四标铜陵长江大桥北岸引桥承台为工程背景,研究拉森钢板桩围堰的设计、工期提升、工艺质量控制等关键技术,为安徽乃至全国的粉细砂层地质开挖提供技术支持与方案比选。

Since the reform and opening up,China's national economy has developed rapidly,and national infrastructure construction has been carried out everywhere,especially with the continuous expansion of the urban circle,road construction is mostly carried out in the form of bridges in order to save land in the city.Therefore,based on the engineering background of Tongling Yangtze River Bridge north bank approach platform in the front four bid sections of the Lutong Project,this paper studies the design,construction period improvement,process quality control and other key technologies of Larssen steel sheet pile cofferdam,providing technical support and scheme comparison for the geological excavation of silty fine sand layer in Anhui and even the whole country.
