Roadbed slope combined protection mechanical efficient construction method

The invention relates to the field of roadbed slope protection construction, in particular to a roadbed slope combined protection mechanical efficient construction method. An arch skeleton base grooveis mechanically excavated; a rotating drill bit is added on an excavator cantilever, and is used for excavating the base groove; the problems of low manual excavation efficiency and high cost in theprior art are solved; and meanwhile, manual finishing molding is cooperated to reduce disturbance on core soil of a slope, so that the overall working efficiency is improved. Excavation reserved soilin an arch skeleton is compacted by adopting a hydraulic flat rammer; and an electric hammer cooperates with the rammer to compact the arc corner positions, so that compact and smooth soil in the skeleton is effectively guaranteed, the excellent conditions are provided for installation of six-edge bricks in the next step, the secondary surface finishing is prevented, the time is saved, and the working efficiency index is im
