Old cement concrete direct overlay construction process and construction equipment thereof

Abstract

The invention discloses an old cement concrete direct overlay construction process and construction equipment thereof, and relates to the technical field of overlay construction, the construction equipment comprises a supporting mechanism, the supporting mechanism comprises a base, and rollers are arranged at the bottom of the base. A transmission wheel is driven to rotate through a rotating motor, then a rotating wheel, a transverse rod, a transmission belt and a rotating shaft are driven to rotate, and then stirring blades on a threaded head are driven to rotate through the rotating shaft, so that asphalt concrete can be stirred in the horizontal direction and the vertical direction at the same time; the asphalt concrete processing speed of the equipment is improved, so that the use efficiency of the equipment is improved, the old pavement paved with an asphalt concrete surface layer is rolled through the road rolling rollers on the connecting arms, then a thin overlay is formed, the strength of the old pavement is improved, stains are resisted through the baffles, and the service life of the old pavement is prolonged. And stains are prevented from being attached to the surface of equipment when the road roller works.

Description

technical field [0001] The invention relates to the technical field of overcoat construction, in particular to an old cement concrete direct overcoat construction process and construction equipment thereof. Background technique [0002] Overlay refers to the fine stone thin asphalt surface layer laid on the original asphalt pavement in order to improve the use quality of the asphalt pavement, improve the waterproof, anti-skid ability and smoothness of the pavement. [0003] The following problems exist for the prior art: [0004] 1. The existing overlay construction equipment generally directly uses rollers to roll the old pavement on which asphalt concrete is applied, and it is easy to cause a large number of stains to be sputtered on the equipment body during the construction process; [0005] 2. The existing overcoat construction equipment generally only relies on a motor and a single baffle as a stirring blade to mix the asphalt concrete. The mixing rate is relatively p...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a direct overlay construction process of old cement concrete and its construction equipment. One of the purposes is to have the function of dustproof protection for the equipment, and solve the problem that the existing overlay construction equipment directly uses roller pairs to apply The old road surface of asphalt concrete is rolled, and a large amount of stains are easily splashed on the equipment body during the construction process; another purpose is to solve the problem that the existing overlay construction equipment only relies on an electrical and single-piece baffle As a mixing blade for mixing asphalt concrete, the mixing effect is not good, and the production speed is slow, so as to achieve the effect of enhancing the mixing speed and uniformity of the asphalt concrete.
