河南省洛阳市东华桥工程采用了钻孔下沉预制空心桩新工艺,经初步实践证明:它是一种改革就地灌注混凝土桩的好方法。简介如下。一、东华桥工程概况洛阳市东华桥为4孔15米预应力钢筋混凝土空心板桥,全长62.42米,桥梁总宽26.5米。下部结构详见图1,墩台的系盖梁 Donghua Bridge Project of Luoyang City, Henan Province, adopted a new process of precast hollow piles with borehole sinking. Preliminary practice proves that it is a good way to reform the in-situ pouring concrete piles. Brief introduction is as follows. I. Introduction of Donghua Bridge Project Donghua Bridge in Luoyang is a 4-hole 15-meter prestressed reinforced concrete hollow slab bridge with a total length of 62.42 meters and a total bridge width of 26.5 meters.
