摘要
随着社会经济的进步,我国的公路桥梁建设也在不断发展,方便了人们的出行。公路桥梁建设的持续增长对公路桥梁的施工技术与质量提出了更高的要求,特别是桩基方面的施工。当前,公路桥梁桩基施工中容易出现孔斜、塌孔、钢筋笼偏位,以及掉钻、卡钻、埋钻等问题,为了避免这些问题的出现,必须从公路桥梁桩基施工建设入手加强管理,从施工前准备阶段做好相关工作,合理应用钻孔、清孔、钢筋笼定位、混凝土灌注等施工技术,这样才能保证公路桥梁工程的安全性和稳定性。
At this stage,with the rapid development of social economy in China,the construction of highway bridges and other traffic areas is also developing constantly,making it convenient for people to travel.At the same time,higher requirements are put forward for the construction technology and quality of highway bridges,especially for the construction of pile foundations.At present,problems such as hole inclination,hole collapse,reinforcement cage offset,drill dropping,drill sticking,and drill burying are easy to occur in the construction of highway bridge pile foundation.In order to avoid these problems,we must strengthen management from the construction of highway bridge pile foundation,do a good job in the preparation stage before construction,and reasonably apply construction technologies such as drilling,hole cleaning,reinforcement cage positioning,and concrete pouring,so as to ensure the safety and stability of highway bridge engineering.
