Machine for constructing concrete pavement of large-span road

Abstract

The invention relates to a machine for constructing the concrete pavement of a large-span road, which comprises a conveying belt, a hopper truck, a right box-type vibrating device and a left box-type vibrating device, a right conveying auger and a left conveying auger, wherein the conveying belt is arranged on a truss; the hopper truck is arranged on a hopper truck traveling gear rail by a hopper truck traveling gear and can move along the hopper truck traveling gear rail; and the right conveying auger and the left conveying auger are arranged on the truss and are connected with two vibrating lifting control devices. By using the road machine, a large amount of distributing equipment and labor for pouring concrete is saved, and the construction quality of road concrete pouring can be ensured. In the road machine, the truss is assembled section by section, so the truss is convenient to install, use, operate and maintain; and the machine integrates concrete distributing, paving, vibrating and leveling, so the construction cost is reduced substantially.

Description

technical field [0001] The invention relates to a road construction machine for large-span road concrete pavement. Background technique [0002] At present, concrete road construction has the characteristics of long construction line, tight construction period, heavy tasks, and large amount of concrete pouring. During the construction process, a large number of road construction personnel need to be invested, and the construction speed is relatively slow. It is not a one-time forming, and it cannot be used for long-distance continuous operation. Sometimes the construction quality cannot be guaranteed, especially in the construction of long-span and wide road pavement, the concrete is directly poured on the road surface, and then paved by road construction workers, which is not only easy Cause the concrete to spread unevenly on the road surface, and the workload is heavy, the concrete piled up for a long time is difficult for vibrating densely, affects the construction qualit...

[0002] At present, concrete road construction has the characteristics of long construction line, tight construction period, heavy tasks, and large amount of concrete pouring. During the construction process, a large number of road construction personnel need to be invested, and the construction speed is relatively slow. It is not a one-time forming, and it cannot be used for long-distance continuous operation. Sometimes the construction quality cannot be guaranteed, especially in the construction of long-span and wide road pavement, the concrete is directly poured on the road surface, and then paved by road construction workers, which is not only easy It causes uneven paving of concrete on the road surface, and the workload is heavy. The concrete piled up for a long time is not easy to vibrate and compact, which affects the construction quality of the entire road surface.

The existing equipment with concrete paving and vibrating can only pave and vibrate in one direction, one-way paving and vibrating, the construction speed is slow, and there are easy dead angles at the edge of paving and vibrating, and follow-up Manual paving, vibrating and leveling are labor-intensive and affect construction quality
