Municipal road before-filling rolling device

Abstract

The invention relates to a municipal road before-filling rolling device. The municipal road before-filling rolling device comprises a connecting frame, a cleaning device, a collecting device, a flattening device, a rolling roller and a transmission device, the cleaning device is connected into the connecting frame through a bearing, the collecting device is mounted on the right of the cleaning device, the collecting device is mounted on the inner wall of the connecting frame, and the problems that when an existing device carries out rolling on a municipal road before filling, a foundation before road filling cannot be cleaned, the phenomenon that garbage on the foundation affects later rolling is prone to appearing, the rolling effect is reduced, meanwhile, an uneven foundation cannot be rolled after flattening firstly, the phenomenon that the rolled foundation is prone to causing inconsistent density is caused, the rolling efficiency and he rolling effect are reduced, a rolling wheelafter rolling cannot be cleaned, after rolling, connecting is prone to appearing, and flatness of the rolled foundation is reduced can be solved.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a pre-filling rolling equipment for municipal pavement. Background technique [0002] The structural layer of the municipal road pavement mainly includes the surface layer, the base layer and the cushion layer. The surface layer is located at the top of the entire pavement structure and is the layer that most directly reflects the performance of the pavement. The materials used to build the high-grade road surface layer are mainly asphalt Concrete and cement concrete, etc., the base layer is located under the surface layer, on the cushion or roadbed, and the base layer mainly bears the vertical force of the wheel transmitted by the surface layer, so it needs to choose high strength, high rigidity, and sufficient water stability. The cushion layer is the layer between the base and the soil foundation. Not all pavement structures need to be equipped with a cushion la...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that the existing equipment cannot realize the function of cleaning the foundation before the road filling when the existing equipment is used for rolling and compacting the municipal road surface, so that the rubbish on the foundation is likely to affect the subsequent rolling, thereby reducing the cost of rolling. At the same time, it is not possible to smooth the raised and uneven foundation first before rolling it. The density of the ground after rolling is likely to be inconsistent, which reduces the efficiency of rolling and the effect of rolling. Moreover, the rolling wheels after rolling cannot be cleaned, and joint phenomena are prone to occur after rolling, thereby reducing the smoothness of the foundation after rolling.
