Cast-in-place box girder construction method for firstly solidifying and then erecting full framing in sea beach area
The invention discloses a cast-in-place box girder construction method for firstly solidifying and then erecting a full framing in a sea beach area, which comprises the following steps of: forming an artificial hard shell layer, a broken stone hardcore and a concrete hardcore on the surface of the sea beach area, then sequentially performing foundation prepressing, erecting the full framing, prepressing a bracket, and cast-in-place box girders on the full framing after removing load. According to the construction method, a shallow foundation treatment method is adopted, the surface bearing capacity of the mud flat foundation is fully exerted, settlement control in the cast-in-place box girder pouring period is achieved, and the problems that in a traditional method, steel pipe piles, trestles and other treatment modes need to be adopted, the manufacturing cost is high, construction is tedious, and the period is long are solved; the construction efficiency is improved, the construction cost is saved, the construction period is shortened, and the cast-in-place box girder can be rapidly built in the sea beach area.
本发明公开了一种海域滩涂地区先固化后搭设满堂支架的现浇箱梁施工方法，通过在海域滩涂地区表面形成人工硬壳层、碎石垫层、砼垫层，再依次做地基预压、搭设满堂支架、支架预压、卸除荷载后在满堂支架上现浇箱梁，这样的施工方法采用浅层地基处理方法，不但充分发挥了滩涂地基表面承载能力，实现了现浇箱梁浇筑期间的沉降控制，还克服了传统方法必须采用钢管桩、栈桥等处理形式中造价较高、施工繁琐、周期长的问题，提高了施工效率、节约了施工造价、缩短了施工周期，能实现在海域滩涂地区快速建造现浇箱梁。
