River-crossing-section double-layer cast-in-place bridge flood-fighting support foundation and construction method thereof
The invention discloses a river-crossing section double-layer cast-in-place bridge flood control support foundation and a construction method thereof.The support foundation comprises a construction platform arranged in a river channel, and the construction platform comprises a sheet pile assembly, a drainage assembly and a foundation; the drainage assembly comprises a plurality of drainage pipe fittings embedded in the foundation, each drainage pipe fitting is formed by splicing a plurality of single pieces, and each single piece comprises a water passing pipe on the innermost layer, a fixing pipe on the middle layer and a supporting pipe on the outermost layer. An original lower structure construction platform is fully utilized, the drainage assembly buried in the foundation is adopted to conduct flow guiding on watercourse drainage under the condition that the watercourse is not recovered, the ground serves as a support platform after being hardened to achieve upper structure construction, the construction cost is reduced, and the construction method is more suitable for middle and small span municipal cast-in-place bridge construction.
本发明公开了跨河段双层现浇桥梁度汛支架基础及其施工方法，其中，支架基础包括设置在河道中的施工平台，所述施工平台包括板桩组件、排水组件和地基；所述排水组件包括若干个埋设在地基内部的排水管件，所述排水管件由若干段单件拼接形成，每个单件包括最内层的通水管、中间层的固定管、以及最外层的支撑管。本发明充分利用了原有下部结构施工平台，在未恢复河道的情况下采用埋设于地基中的排水组件对河道排涝进行导流，地面硬化后作为支架平台实现上部结构施工，降低了施工成本，更加适用于中小跨度的市政现浇桥梁施工中。
