Asphalt paving device for preventing cracks from being formed on pavement in rainy season environment

Abstract

The invention discloses an asphalt paving device for preventing cracks from being formed on a pavement in a rainy season environment in the technical field of road construction. The device comprises: a shell assembly, wherein the right side of a left shell is fixedly connected with a right shell; a tank clearing assembly, wherein the outer wall of a rotary drum is sleeved with driving gear rings which are arranged up and down; and a repairing and paving assembly comprising a pressing rod which is movably inserted into the inner cavity of the rotary drum, wherein the bottom end of the pressing rod is fixedly connected with a pressing disc. A drill bit part with a groove formed in the bottom surface is matched with a suction inlet, a driving shaft drives the rotary drum to rotate, and if cracks are caused by longitudinal displacement difference of the pavement, the balance state between the pressing disc and the pavement is broken, so that a balance rod is pushed out of the inner cavity of the pressing disc, supplementary materials are pressed into the pavement again, air flow continuously flows in the annular cavity, and drives the annular concentric plate to rotate continuously to make the supplementary materials trowelled, and then cracks in the pavement are found and treated quickly in time, so subsequent reworking operation is avoided, and the pavement construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an asphalt laying device for crack formation on the road surface in the rainy season environment. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can also use rigid cement concrete or semi-rigid hydraulic materials. [0003] Construction in the rainy season environment, due to the wet road surface and the infiltration of rainwater, it is easy to cause large-sc...

AI Technical Summary

Problems solved by technology

[0003] Construction in the rainy season environment, due to the wet road surface and the infiltration of rainwater, it is easy to cause large-scale potholes and damage to the road surface, and the asphalt pavement will collapse and crack. During the process of rolling and rolling, the temperature of the surface decreases, and the temperature at the bottom is higher. When compacting, the mixture in the middle and lower parts will generate a large shear stress and cause a difference in longitudinal displacement, and the upper layer will be deformed and shrunk. , which in turn causes cracks, potholes or looseness of the road surface, which reduces the quality of construction. For this reason, we propose a paving device for asphalt cracks in the rainy season environment
