Description
Technical Field
The invention belongs to the technical field of engineering mechanical equipment and construction methods required by road and airport construction, maintenance and repair and other pavement operations. In particular to a synchronous chip sealer.
Background
The synchronous chip seal technology becomes an important component in road construction and pavement maintenance and repair engineering. The synchronous chip seal is carried out by spraying asphalt (modified asphalt, etc.) and spreading mineral aggregate simultaneously, so that the asphalt binder and mineral aggregate have sufficient contact to reach maximum adhesion degree to form a thin layer of pavement. 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 road surfaces, airport runways and the like. Effectively improve road service performance and prolong road service life. The synchronous gravel seal layer paving equipment and the construction technical method have important influence on construction quality and performance.
At present, the domestic synchronous chip sealer construction generally adopts an operation mode that a synchronous chip sealer vehicle carries out an intermittent process. The method comprises the steps of firstly filling raw materials such as mineral aggregate, asphalt and the like in a stock yard, then driving the stock yard to a construction site to carry out construction operation, and when a certain raw material is used up, obtaining the stock yard again to be filled, and repeating the construction. Because synchronous chip seal car is every full a car raw and other materials quantity restriction, the area that can pave is limited to different width and mineral aggregate density and pitch spraying volume restraint in addition, and equipment must return to the stock ground and install the raw and other materials in the construction of long distance big engineering and arrive at the building site again and carry out the construction operation next time. 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 produced stub bars influence the overall construction quality in different degrees.
At present, the prior continuous type synchronous macadam seal equipment and technology adopts an asphalt spreader to spray asphalt firstly, and then the continuous type macadam spreader spreads mineral aggregate. However, the foreign continuous equipment introduced in the real production has not been accepted and recognized by the domestic market and industry for a long time! The synchronous broken stone seal layer vehicle construction is widely used in China for a long time. Although the related technologies of continuous synchronous chip sealer and construction method are disclosed and introduced in quite a lot of literature documents, the operability, popularization, reliability, construction quality, cost and the like of the continuous synchronous chip sealer are far from the comprehensive application performance of the synchronous chip sealer, and the real object is rarely seen in the actual production. The reason for this phenomenon is mainly three-fold: firstly, the existing continuous and synchronous chip sealer has strict requirements on the level of construction operation and managers; secondly, the continuous feeding process is complicated, the operation is not easy, and the construction quality is difficult to control; and then the continuous, smooth and stable matching operation among matched equipment is achieved, and the operation is complex and very difficult. The above problems have been long-standing.
Because the existing equipment design shows: the effective power of the equipment is limited, and the spraying and spreading width is limited, so that the one-time performance of the existing continuous and discontinuous synchronous stone crushing process meets the requirement of spreading the stone in the width of one lane. Therefore, the pavement of more than two lanes adopts a sequential splicing mode, so that the distribution ratio generated at the longitudinal and transverse joints is not uniform, the flatness of the joints is easy to generate unevenness and leakage pavement, the lap joint bonding degree and strength of the joints are unstable, and the quality problems of the integral pavement flatness, appearance color difference and the like are very difficult to control.
A great deal of research at home and abroad shows that the inadequate treatment between pavement layers is one of the important reasons for causing the quality problem of the pavement of the synchronous chip seal. Because the original road surface layer and the slurry seal layer or the micro-surface layer are two materials and processes with different structures, if the interlayer binding power is insufficient, the load, particularly heavy load and overload, brought by road traveling is added alternately in four seasons through the natural environment, and the interlayer extrusion and shearing deformation are accumulated continuously, so that the slurry seal layer or the micro-surface pavement has road surface diseases such as premature falling, cracks, pitted surfaces, oil bleeding and the like.
In addition, the existing equipment design scheme shows that: the effective power of the equipment is limited, and the functionality is single, so that when the prior synchronous chip sealer is used for preprocessing the pavement, the pretreatment needs to be carried out in advance by using separate equipment. Therefore, the scattered mineral aggregate in the construction process can not be cleaned in time, the bonding quality problem is caused, and the overall paving quality effect is directly influenced. In particular to a method for preprocessing the road surface before the synchronous gravel paving construction at present, which generally adopts non-special cleaning equipment and a shoulder portable blower to preprocess the road surface before the construction. The method obviously has very limited cleaning effect on the road surfaces of 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, uneconomical and not suitable for carbon peak reaching and carbon neutralization.
The above problems have not been solved effectively.
