多跨连续梁跨水源保护区成套施工技术

The Whole Sets of Construction Technology of Multi-span Continuous Beam across Water Source Protection Area

大广高速公路流溪河特大桥所跨河道为广州市二级水源保护区,环保要求高,水文条件复杂,因此要在高环保要求下开展相关施工技术研究,主要研究内容为:深厚卵石层钢管桩打设施工技术、斜交墩0#块支架搭设施工技术、钻孔桩泥浆孔内循环施工技术。

The river Liuxihe grand bridge of Daguang expressway crosses is a second-grade water source protection zone of Guangzhou with high environmental requirements and complex hydrological conditions, so the relevant research on construction technology should be carried out in the high environmental protection requirements. The main contents include construction technologies of thick gravel layer steel pipe driving, oblique pier 0# scaffold erection and bored pile hole inner circulation.
