水上曲线形鱼腹式现浇钢筋混凝土箱梁支模技术研究

Study on Cast-in-situ Reinforced Concrete Box Girder with Curved Fish-Belly

曲线性鱼腹式桥梁是现代交通中的一种重要桥型,此桥型线条优美,造型轻巧,适合复杂地形,常用于陆地上,如城市立交桥的匝道和穿越复杂山区的桥梁。曲线桥身常采用预制吊装施工。水上曲线型鱼腹式满堂支架支模现浇施工较为罕见,目前此类施工经验尚少,文章以清远市滨江公园市政景观桥水上曲线形鱼腹式现浇钢筋混凝土箱梁施工为例,详细阐叙此类桥梁混凝土梁身支模独特的关键施工技术。

Curved fish-abutting bridge is an important bridge in modern traffic.It is beautiful and light in shape, suitable for complicated terrain.It is commonly used on land, such as ramp of city overpass and bridge crossing complex mountain.Curved bridge body is usually used prefabricated lifting construction.In this paper, Qingyuan City, Riverside Park, landscape curved fish-shaped cast- in-situ fish-style cast-in-place reinforced concrete box girder of construction, for example, in the construction of the water-This paper expounds the key construction technology of this type of bridge beam concrete beam in detail.
