摘要
随着我国经济建设的不断发展,跨越大江大河的桥梁越建越多,而我国幅员辽阔,水文、地质复杂多变,水下基础工程施工不可预见的因素较多,施工难度大;以安徽省淮南孔李淮河大桥跨越淮河主航道桥工程为例,针对复杂水文地质条件,合理选择双壁钢围堰下沉控制的各种技术措施,并发明了一种实用新型专利的导向装置,大大提高了双壁钢围堰的定位精度,保证了双壁钢围堰顺利下沉,为今后同类型工程的施工提供了很好的借鉴意义。
With the continuous development of China＇s economic construction, the bridges across the river are more and more, but China has a vast territory, hydrology and geology are complex and changeable, underwater foundation engineering construction is not predictable, the construction is difficult. Taking Konglihuaihe bridge in Huainan across the Huaihe as an example, in view of the complex hydrogeological conditions, this paper makes a reasonable choice of various technical measures for double wall steel cofferdam subsidence control, invents a guiding device of the utility model, which greatly improves the positioning precision of the double wall steel cofferdam, ensures the smooth sinking of the double wall steel cofferdam, and provides a good reference for the future construction of the same type engineering.
