Cast-in-place box girder support
The invention discloses a cast-in-place box girder support which comprises a plurality of support units distributed in the bridge direction of a cast-in-place box girder, each support unit comprises a plurality of PHC pipe piles distributed in the transverse direction of the cast-in-place box girder, a bearing platform is fixedly arranged at the tops of the PHC pipe piles, and a first steel pipe pile is arranged at the top of the bearing platform; the first steel pipe piles are connected through connecting supports, unloading sand boxes are arranged on the tops of the first steel pipe piles, distribution beams are arranged on the unloading sand boxes, and bailey beams are arranged on the distribution beams. According to the cast-in-place box beam support, the cast-in-place box beam support is formed by the steel pipe piles, the bailey beams and the distribution beams, the cast-in-place box beam support can be suitable for soft soil foundations and can also be suitable for the cast-in-place box beam construction environment with the clearance limited, the influence of foundation settlement on supporting of the cast-in-place box beam support structure is avoided, the PHC pipe piles do not need to be pulled out after being implanted into the foundation, and the construction efficiency is improved. The construction time is effectively saved, and the construction efficiency is improved.
本发明公开了一种现浇箱梁支架，包括沿现浇箱梁的桥向分部的多个支架单元，支架单元包括沿现浇箱梁横向分部的多根PHC管桩，PHC管桩的顶部固定设置有承台，承台的顶部设置有第一钢管桩，第一钢管桩和第一钢管桩之间通过连接支架相连接，第一钢管桩的顶部设置有卸荷砂箱，卸荷砂箱上设置有分配梁，分配梁上设置有贝雷梁。本发明提供的现浇箱梁支架，通过钢管桩+贝雷梁+分配梁形成现浇箱梁支架，使其既能够适用于软土地基，又能够适用于净空受限的现浇箱梁施工环境，避免地基沉降对现浇箱梁支架结构的支护造成影响，并且PHC管桩植入地基后无需拔除，有效的节省了施工时间，并提高施工效率。
