Detailed Description
Example (b):
the invention provides a method for integrally paving a single asphalt concrete pavement with the width of more than 18m, which comprises the following steps:
s1: the discharge amount of the spreader is adjusted. The spreader is provided with a spiral conveying groove, and a spiral shaft for conveying materials is arranged in the spreader. The diameter and pitch of the blades of the screw shaft affect the discharge amount. Therefore, the discharge amount of the spreader is controlled by adjusting the diameter and pitch of the blades of the screw shaft. The blade diameter at each position in the spiral conveying groove has five gears of 480mm, 420mm, 360mm, 320mm and 280 mm. The screw pitch of all positions in the spiral conveying groove has three gear positions of 280mm, 420mm and 560 mm.
The screw shaft can be divided into several sections, the diameter and pitch of the blades of each section are controlled separately, and the rotation speed of each section is controlled separately. This just can be effectual the discharge capacity of guaranteeing the paver everywhere different. And different paving thicknesses of different lanes are ensured.
S2: and (5) paving the road surface.
S3: and detecting the paving quality of the paved section. Paving quality includes pavement flatness and pavement segregation. And immediately detecting the paving quality after paving.
S4: and finely adjusting the discharge amount of each paver according to the paving quality. Specifically, the discharge amount of the paver is adjusted according to the pavement flatness. The blade diameter of each position in the spiral conveying groove is provided with five gears; the screw pitch of each position in the spiral conveying groove is provided with three gears. In practice, when fine adjustment is performed, the gear positions within the interval between the gear positions cannot be adjusted when the gear positions within the interval are required. And the adjustment can be carried out in a mode of matching adjacent gears. For example, currently it is desirable to adjust the blade diameter to 460mm, the blade diameter may be adjusted to 480mm for a certain period of time before being adjusted to 420mm for a certain period of time. The final discharge and the discharge when the blade diameter is 460mm can be ensured by adjusting the running time ratio of the two blade diameters.
The method for integrally paving the single asphalt concrete pavement with the thickness of more than 18m adjusts the discharge amount of the paver, so that the discharge amounts of a new road and an old road are different. The discharge capacity of the old road side is greater than that of the new road side, and therefore the problem that the new road side and the old road side generate height difference due to large settling amount of the new road side after pavement construction is completed and put into use is avoided. The quality of the pavement is ensured. Meanwhile, the discharge amount of each lane is also adjusted. The road surface unevenness caused by the fact that the heavy lanes, the traffic lanes and the emergency lanes are not settled uniformly is avoided.
In addition, the paving quality was measured immediately after the paving was finished. Meanwhile, the discharging amount of the spreader is finely adjusted according to the spreading quality. The discharging amount of the rear paving is obtained according to the paving quality correction, so that the discharging amount of the rear paving is more accurate. Meanwhile, the discharge amount is continuously finely adjusted, the paving amount of each part and the adjacent part after paving is finished is corresponding, and the continuity of longitudinal connection of the road surface is better. Avoid because of the road bed discrepancy in height and the volume of paving remain invariable throughout and lead to comparatively obvious discrepancy in height to appear around the road surface.
In step S1, the amplitude of the front vibrator and the amplitude of the rear vibrator need to be adjusted. In step S4, the amplitude of the front vibrator and the amplitude of the rear vibrator are adjusted according to the degree of pavement segregation. The amplitude of the front vibrator and the amplitude of the rear vibrator jointly determine the segregation degree of the materials. The amplitude of the front vibrator and the amplitude of the rear vibrator are corrected in time according to the detected pavement segregation degree, and further serious material segregation is avoided.
The amplitude of the front vibrator has five gears of 0, 3, 6, 9 and 12. The amplitude of the rear vibrator has five gears of 0, 3, 5, 7 and 9. In the adjustment, the gear position may be adjusted to an appropriate value as needed.
In this embodiment, a plurality of material level indicators are arranged in the spiral conveying chute. The plurality of material level devices are connected with the controller. The controller adjusts the discharge amount of each part of the spiral conveying chute according to the data of the plurality of material level devices. The plurality of material level devices monitor the discharge amount of each part in the spiral conveying groove together, so that the discharge amount of each part in the spiral conveying groove is kept at a proper value.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
