Cast-in-place beam support for soft foundation bridge in coastal area

A cast-in-place beam support for a soft foundation bridge in a coastal area is characterized in that a plurality of rows and columns of steel pipe columns are vertically driven into a soft foundation bearing stratum, I-shaped steel is arranged at the tops of longitudinal steel pipe columns, a bailey beam is transversely arranged on the I-shaped steel, a plurality of groups of II-shaped steel are longitudinally arranged on the bailey beam at intervals, and a full framing is transversely arranged on the II-shaped steel; the foundation bearing capacity is improved by adopting the steel pipe piles, the bailey beams and the full framing, and the framing is low in construction cost, stable in stress, large in safety coefficient, capable of safely and effectively completing cast-in-place beam construction and capable of being widely popularized in coastal areas. 一种沿海地区软基桥梁现浇梁支架,在软基持力层竖向打入若干行若干列钢管柱，纵向钢管柱顶部设置有一号工字钢，一号工字钢上横向设置有贝雷梁，贝雷梁上纵向间隔设置有若干组二号工字钢，二号工字钢上横向设置有满堂支架；本装置采用钢管桩+贝雷梁+满堂支架提高了地基承载力，该支架形式施工成本较低，支架受力稳定，安全系数较大，能
