The invention belongs to the technical field of road engineering, and particularly relates to an expressway pavement finishing device which comprises a vehicle body and a milling roller. The milling roller is rotationally connected with the vehicle body through a bracket and is driven by a hydraulic motor to rotate; a group of oil cylinders are arranged at the bottom of the vehicle body at the side, close to the tail of the vehicle body, of the milling roller, driving units are fixedly connected to the ends of piston rods at the tops of the oil cylinders, and drilling barrels are rotationally connected to the bottoms of the driving units and penetrate through holes in the bottom of the vehicle body; the drilling barrels are driven by the driving unit to rotate; a storage box is fixedly connected in the vehicle body, the bottom of the storage box is communicated with a concrete pump, and an outlet of the concrete pump is rotationally and hermetically connected with the drilling barrel through a pumping pipe; sunken roadbed is uniformly punched through the drilling cylinder, and then rapid hardening concrete is pumped into the drilled hole through the concrete pump to form a pile. Thus, the bearing capacity of the roadbed is increased, and the recurrence of pavement injuries is reduced.
本发明属于道路工程技术领域，具体的说是一种高速公路路面修整装置，包括车体和铣刨辊；铣刨辊通过支架与车体转动连接，铣刨辊通过液压马达驱动旋转；铣刨辊靠近车体尾部一侧的车体底部设有一组油缸，油缸顶部的活塞杆端部固连有驱动单元，驱动单元底部转动连接有钻筒，钻筒贯穿车体底部的开孔；钻筒通过驱动单元带动旋转；车体内固连有储料箱，储料箱底部连通有混凝土泵，混凝土泵的出口通过泵送管与钻筒转动密封连接；通过钻筒对凹陷处路基进行均匀的打孔，之后通过混凝土泵向钻孔处泵入速凝混凝土成桩，增加路基的承载力，减少路面伤病复发。
