摘要
结合光辉大桥施工实例,根据工程项目特点及施工作业条件,通过方案比选,创新性的采用冲孔开槽置桩、在围堰内外两侧抛填沙袋等的工艺,有效解决了钢板桩围堰在深水、浅覆盖层、河床下覆岩层较硬等恶劣环境下的适用性难题,同时提高了工效、节约了成本,对类似项目极具借鉴意义。
In this paper,combining the construction of bridge glory,according to the project characteristic and construction conditions,through scheme comparison,the innovative adopt the punching slot piles on both sides,both inside and outside the cofferdam fill sandbags,such as technology,effectively solve the steel sheet pile cofferdam in the deep and shallow overburden,riverbed overburden stratum under hard conditions under the applicability of the problem,and raised the working efficiency,saving the cost and reference significance for similar projects.
