Description

Concrete pavement spreader Technical Field The utility model belongs to the technical field of construction equipment, and particularly relates to a concrete pavement spreader. Background In modern road construction, with rapid increase of urban traffic flow, ultra-wide road surfaces of two-way eight lanes and above have become the main stream configuration of high-grade roads. The traditional concrete paving equipment generally adopts an integral vibration compression roller structure, and the working width of the integral vibration compression roller structure is limited by the characteristics of material strength and structural rigidity. Engineering practice shows that when the length of the press roller exceeds 8 meters, remarkable middle flexural deformation can be generated in continuous vibration compaction operation, road surface flatness index is directly affected, and even structural failure of the press roller is caused when the road surface flatness index is severe. Prior art to address this problem, a multi-segment press roll splicing scheme is typically employed. However, the scheme has two technical defects that firstly, the axial gap formed between adjacent compression roller sections can cause the accumulation of concrete materials to form longitudinal bulges, secondly, in order to eliminate joint marks, a construction party needs to be provided with 2-3 auxiliary workers for carrying out real-time scraping operation, so that the labor cost is increased by 15% -20%, and the plasticity of the initial-setting concrete is reduced due to the hysteresis of manual operation.
