Description

Road paving device for human living environment remediation

Technical Field

The invention belongs to the technical field of pavement construction, and particularly relates to a road paving device for repairing a living environment.

Background

The human living environment is the environment in which the human living is living. In the living environment, the road is smooth and tidy, and the convenience of traveling of residents and the comfort of living are closely related. For some remote areas, the situation that the resident areas are uneven in the road is still existed, and the road paving device is required to be adopted to remedy the local road surface. For concrete pavement which is lost over time, severe cracking and deformation can occur, and the pavement needs to be re-paved at the moment.

The flat vibrator is a road paving device commonly used in the concrete pavement paving process. When the concrete is paved, the concrete raw materials are stirred through a concrete mixer to form concrete mixture, and after the concrete mixture is conveyed to a paving area, the concrete is vibrated by using a flat vibrator, and meanwhile the concrete is leveled. The existing flat vibrator is provided with a flat plate for vibration and a vibration motor for providing vibration for the flat plate, and after the motor is started, the flat vibrator is dragged forwards or backwards at a proper speed, so that the pavement can be vibrated and leveled.

In order to avoid segregation of concrete, the slab vibrator cannot vibrate the concrete mixture in the same area for a long time. For a paving area with wider pavement and a paving area with larger pavement width variation degree, the area needs to be divided into a plurality of rows, the vibration and leveling of each row of concrete mixture in the whole paving area are realized by steering or transversely moving a flat plate of a vibrator, and the vibration time of a part of areas is longer in the steering and transversely moving processes of the flat plate; in addition, in order to avoid the occurrence of the vibration leakage phenomenon, the concrete mixture areas of the adjacent columns need to have a certain contact ratio, the concrete in the concrete mixture areas of the adjacent two columns is also easy to vibrate for a long time, and the situation of concrete segregation is easy to occur under the condition of excessive vibration time, so that the concrete coarse aggregate in the partial areas is sunk, and the overall strength of the concrete pavement is reduced.
