Description

Micro-surfacing paver

Technical Field

The utility model belongs to the field of engineering machinery required by road and airport construction, maintenance and repair and other pavement operations. In particular to a slurry seal vehicle and micro-surfacing paving equipment.

Background

Micro surfacing and slurry sealing technologies have become an important component in road construction and pavement maintenance and repair projects. The micro-surfacing and slurry sealing is that a slurry mixture is formed by continuously mixing stone grains or sand, stone powder, cement, water and additives with certain gradation with emulsified asphalt (high molecular polymer modified emulsified asphalt), then the mixture is quickly and uniformly spread on the road surface to be constructed, and then the processes of emulsion breaking, water separation, evaporation, solidification, forming and the like are carried out to form a sealing or rutting filler. The method can be used for performing preventive maintenance, early maintenance, rut filling and repairing, pavement appearance improvement and the like on the surface function of the road. The adhesive has the functions of adhesion, water resistance and the like in the lower sealing layer in the construction of the road surface and the airport runway. Effectively improves the road service performance and prolongs the service life of the road. Micro-surfacing, slurry seal paving equipment and a construction technical method have important influence on construction quality and performance.

At present, the micro surfacing and slurry seal construction in China generally adopts a slurry seal vehicle to carry out paving operation in an intermittent process. The method comprises the steps of filling raw materials such as mineral aggregate, emulsified asphalt, water and the like in a stock yard, driving the stock yard to a construction site for construction operation, obtaining the stock yard again when a certain raw material is used up, and repeating the construction. The limited quantity of raw materials is limited when the slurry seal vehicle is filled with one vehicle, and only a limited area can be paved due to the requirements of different widths and thicknesses; in the long-distance large engineering construction, the equipment must return to a stock yard to be additionally provided with raw materials and then drives to the construction site again to carry out the next construction operation. Therefore, most time of equipment is wasted on transporting raw materials, high equipment utilization rate is low, and construction efficiency is not ideal. Usually, a plurality of devices are adopted to sequentially operate in turn in large-scale engineering, so that the paving joint is easy to frequently occur in the long-distance construction process to influence the quality of the whole pavement. The low-speed and constant-speed running of the truck chassis under the working conditions of heavy load and load change in the construction process is difficult to control; the low-speed and uniform-speed running range of the truck chassis is very limited, and the control and the adjustment are more difficult to realize under the working condition of heavy load and load change. The reduction ratio of the truck chassis gearbox is also troubled by the fact that the low-speed construction speed and the high-speed transportation running speed cannot be achieved at the same time. Different operation personnel of different model equipment often can take place different shop front quality phenomena at same construction road section construction operation, especially different appearance quality problem. In addition, each operation necessarily generates a process stub bar, and the process stub bar is generally discarded. The generated stub bar waste is accumulated on the total engineering quantity in a non-small amount, so that a large amount of non-renewable resources are wasted, the capital loss is caused, and the natural environment is damaged.

Although the existing continuous micro-surfacing equipment can avoid the problems of frequent generation of stub bars, joints and the like in an intermittent process theoretically, the theoretical construction quality and the construction efficiency are superior to those of intermittent process construction. However, most of the existing continuous slurry seal vehicles and continuous micro-surfacing equipment currently need special supporting equipment, and one type is as follows: the special material transfer vehicle is provided with emulsified asphalt, water and mineral aggregate supply on the same vehicle; the other is that: and feeding materials right in front of the slurry vehicle by adopting independent continuous feeding equipment, and sequentially conveying the emulsified asphalt, the water and the mineral aggregate in batches by the material conveying vehicle, the feeding equipment and the slurry seal vehicle in sequence. But the foreign continuous equipment introduced in the real production has not been accepted and recognized by the domestic market and the industry for a long time! Slurry seal vehicle-type micro-surfacing equipment construction is widely used in China for a long time. Although the related technologies of continuous micro-surfacing or slurry seal equipment and construction methods are disclosed and introduced in quite a lot of literature documents, the operability, popularization, reliability, construction quality, cost and the like of the related technologies are far from the comprehensive application performance of slurry seal vehicles, and the real objects are rarely seen in actual production. The reason for this phenomenon is mainly three-fold: firstly, the existing continuous slurry seal or micro-surfacing equipment has strict requirements on the level of construction operation and management personnel, the loading process is complicated, the equipment is not easy to operate, and the construction quality is difficult to control; secondly, special matching equipment matched with the special matching equipment needs to be adopted, and particularly, the overall use cost of the matching equipment is high; and then the continuous, smooth and stable matching operation among matched equipment is complicated and very difficult. The above-mentioned historical problems have long existed.

Because the existing equipment design shows: the effective power of the equipment is limited, and the capacity for stirring the emulsified asphalt mixture is limited, so that the existing continuous and discontinuous micro-surfacing process can only meet the requirement of paving the asphalt mixture in the width of one lane at one time. Therefore, the lanes with more than two widths are spliced and paved in sequence, segregation occurs at the longitudinal joint, the flatness of the longitudinal joint is easy to generate high-low dislocation, the lap joint bonding degree and the strength of the longitudinal joint are weak, and the quality problems of the flatness of the whole pavement, the appearance color difference and the like are very difficult to control.

A great deal of research at home and abroad shows that the improper treatment between pavement layers is one of the important reasons for causing the quality problem of micro-surfacing or slurry sealing pavement, because the original road surface layer and the slurry sealing or micro-surfacing surface layer are two materials and processes with different structures, if the interlayer binding force is insufficient, the load caused by road running is added alternately in four seasons in the natural environment, particularly heavy load and overload, and the extrusion and shear deformation between the layers are continuously accumulated, so that the problems of premature falling, cracks, rough surfaces, pushing, uneven pavement and the like of the slurry sealing or micro-surfacing pavement are caused.

In addition, the existing equipment design scheme shows that: the effective power of the equipment is limited, and the functionality is single, so that the prior micro-surfacing pretreatment process for the pavement needs to be carried out in advance by using separate equipment. Thereby the unrestrained mineral aggregate can't in time be cleared up in the work progress, must cause the device of paving to be raised in a same place and slide produced quality problems such as lou material, race material, directly influence the quality effect that paves. In particular to a method for pretreating the road surface before paving construction at present, which generally adopts non-special cleaning equipment and a shoulder portable blower to pretreat the road surface before construction. The method obviously has very limited road surface cleaning effect on the deposited ash layer, the asphalt oxidation layer, the unstable material and the like of the original road surface, and can not meet the design requirement of the construction process. And the method is very labor-consuming, time-consuming, low in construction efficiency, large in occupied equipment and manpower, high in construction cost and uneconomical.

The above problems have not been solved effectively.
