摘要
结合象山隧道2号斜井施工段地质情况,介绍了采用竖直投料孔向斜井洞内输送混凝土的总体施工方案,并具体阐述了施工方法及工艺,提出了堵管的预防和处理措施,从而解决了进料和出渣的分离问题,对同类工程具有指导意义。
By combining with the geological situation in No.2 inclined shaft construction section of Xiangshan tunnel,the paper introduces the general construction scheme of transferring concrete to the inclined shaft by using the vertical feeding hole,indicates its construction method and craft,and points out the prevention of the pipe blocking and treatment measures,so as to solve the isolation problem of feeding and mucking,and have direction significance for similar projects.
