Bridge abutment lifting construction method for reconstruction and extension of expressway
The invention discloses a bridge abutment lifting construction method for highway reconstruction and extension. The method comprises the following steps that supporting and protecting walls are driven into middle separation belts of a highway respectively, and then half old roadbeds are excavated to the bottom faces of the roadbeds respectively; (2) construction of a plurality of drilled piles, a half new bearing platform, a plurality of bearing platform bodies, a cap beam, a back wall and a lug wall is completed in sequence, earthwork filling and connecting beam plate erecting are completed, and normal traffic of a reconstructed half pavement is achieved firstly, and (3) lifting reconstruction construction of the other half new bearing platform is completed. According to the method, the problem that the other half of the new bearing platform cannot continue to be communicated when the half of the new bearing platform is lifted for construction is solved, meanwhile, it is guaranteed that when the half of the new bearing platform is constructed, disturbance cannot be generated to platform back earthwork of the constructed other half of the new bearing platform, and normal and safe passing of vehicles on the vehicle passing side of the other half of the new bearing platform is guaranteed. The construction difficulty is reduced, the construction safety is ensured, the construction difficulty of the supporting wall and the construction cost of bridge abutment lifting are remarkably reduced, and the construction efficiency is improved.
本发明公开了一种高速公路改扩建的桥台升高的施工方法：包括以下步骤：在高速公路中隔带处分别打入支护墙，然后分别挖掘半幅旧路基至路基底面。2)依次完成多根钻孔桩－半幅新承台－数个承台台身－帽梁、背墙和耳墙的施工，并完成土方填筑和架设连接梁板，使得改建好的半幅路面先正常通车，3)完成另半幅新桥台的升高改建施工。本发明解决了半幅新承台抬高施工时导致另半幅无法继续保通的难题，同时保证了半幅新承台施工时，不会对已施工结束的另半幅新承台台背土方产生扰动，确保另半幅通车侧车辆的正常安全通行。本发明降低了施工难度，确保施工安全，且显著降低了支护墙的施工难度和桥台升高的施工成本，提高了施工效率。
