Description
Technical Field
The invention relates to a paver, in particular to a continuous feeding system of the paver and a continuous micro-surfacing paver adopting the feeding system.
Background
With the rapid development of highway construction in China, the construction and use of a large number of highways make the task of road maintenance more and more important, especially the maintenance of high-grade highways. The contents of the maintenance and repair of the high-grade highway pavement include several modes of pavement surface treatment, local pavement repair, crack filling, pavement renovation and reconstruction and the like. Slurry seals are one type of treatment for the surface of a pavement that is a close-graded mixture of aggregate, emulsified asphalt, mineral fines, additives and water. The operation time of slurry seal is short, and the traffic can be quickly recovered; the road surface structure can be improved, the waterproofness is improved, the friction coefficient of the road surface is increased, and slight crack repair and rut filling can be carried out. In particular, with the improvement of the quality of micro-surfacing technology, the modified emulsified asphalt slurry seal technology is increasingly adopted in the pavement maintenance of high-grade highways (including expressways).
At present, most of slurry layer sealing machines at home and abroad are in an intermittent operation mode, namely, aggregate, emulsified asphalt, water, mineral fine materials and the like are filled in a stock ground, then construction operation is carried out on the stock ground, and after the construction is finished, the stock ground is pulled, and the operation is repeated. Because the efficiency of slurry seal is very high when the construction operation: when a whole car of raw materials (9m of aggregate, 2.5T modified emulsified asphalt, water and the like are filled up and a seal layer with the thickness of 8mm is paved) is filled up, 1200-1500 square meters can be paved in only 12 minutes. However, due to the intermittent operation mode, the slurry sealing machine must unload the spreading box and go to a temporary material factory for loading after the spreading is finished. Each time of feeding is about 30 minutes, if construction on a highway is required to drive according to a specified access and return from a next exit, the time is longer (for example, the time for one round trip of the highway back and forth by 40Km from a stock yard to a construction site is 1.5 to 2 hours at minimum, and 5 vehicles are dry at most in one day), so that the working efficiency of each slurry sealing machine is reduced and is often less than 30 percent, and for this reason, in some places, in order to improve the power, a plurality of slurry sealing machines have to be used, the materials are transported circularly, and a paving box is shared. This undoubtedly increases the equipment investment cost. In order to solve the contradiction, a convenient and fast feeding device is needed urgently, and the transportation vehicle, the feeding device and the slurry sealing machine are matched, so that the materials can be quickly fed on site, the continuous operation of the spreading machine is realized, and the road is not occupied during feeding.
Moreover, the loading of aggregate of most slurry seal machines at home and abroad is finished by a loader at present, so that a stock ground is required, and the operation is finished by the special matched loader, so that the inconvenience is brought to operation construction, the equipment investment cost and the operation cost are increased, and the resource waste and the cost are increased.
