Efficient roadbed flattening device for highway engineering construction

Abstract

The invention relates to the technical field of highway engineering flattening devices, and discloses an efficient roadbed flattening device for highway engineering construction.The efficient roadbed flattening device comprises a pressing wheel fixing frame and a pressing wheel roller body, and the left end and the right end of the pressing wheel roller body are connected to the left inner wall and the right inner wall of the pressing wheel fixing frame through rotating shafts correspondingly; holes are evenly distributed in the outer side wall of the pressing wheel roller body in the circumferential direction, a rolling sliding block is arranged in each hole, a weight adjusting inner cylinder is arranged in the pressing wheel roller body, supports are fixedly connected to the top faces of the left end and the right end of the pressing wheel fixing frame, and air pumps are fixedly connected to the top faces of the left ends of the supports. The left side and the right side of the bottom end of the pressing wheel fixing frame are each provided with two supporting connecting rods, the top face of each supporting connecting rod is provided with a hydraulic telescopic rod, operation is easy, use is convenient, and the claw rolling effect can be achieved without carrying, disassembling and installing a claw roller; and the working intensity of constructors is effectively reduced, and the construction efficiency of highway engineering is effectively improved.

Description

technical field [0001] The invention relates to the technical field of roadbed flattening, in particular to a high-efficiency roadbed flattening device for highway engineering construction. Background technique [0002] The subgrade has various cross-sections according to its filling and excavation height and terrain. Subgrade design mainly includes subgrade body engineering design, subgrade protection and reinforcement engineering design, and subgrade support engineering design. [0003] However, the existing highway subgrade needs to be flattened during the laying process to ensure the stability of the subsequent concrete pouring. Most of the existing highway subgrade is flattened by a roller, which is a heavy roller. Repeatedly moving on the road subgrade to achieve subgrade leveling, because the weight of the pressure roller is not adjustable, this will cause the subgrade to be flattened repeatedly, and the amount of one-way flattening is small, resulting in the subgrade...
