Milling machine set off new power for road reconstruction

In late September, the management section of Gejiu Highway introduced asphalt pavement milling machine for the first time for pavement treatment. In a short period of two days, more than 10,000 square meters of pits and subsidence were treated, which not only greatly accelerated the progress of road repair, but also significantly reduced the impact on passing vehicles. "The asphalt pavement milling machine is too good. It was supposed to work for more than a month and it was finished in two days. The work efficiency is really high." A road worker said. Before the road repair need to use artificial or mechanical road after the eradication of broken, not only the construction speed is slow, but also produce noise and dust, after the use of milling machine greatly shorten the road surface repair time, compared with the previous traditional construction methods, not only greatly improve the speed, repair quality is also very high. The labor intensity, operation safety and working environment of the staff have been greatly improved. The asphalt pavement milling machine can lift 20 to 30 meters of damaged road surface in one minute, and can clean 500 square meters of road surface per hour, while the manual digging and mending pits is only 6 square meters per day. Not only that. It strips off the damaged road surface evenly, does not hurt the roadbed, and is easy to resurface. After milling, a neat and flat milling surface and a straight milling boundary are formed to create conditions for re-paving of asphalt mixtures. After repair, the new and old paving layers are well connected and the joints are flush. The cut asphalt mixture can be directly used for the pavement surface layer, mixed with new asphalt heating, and then re-paved with high-quality surface layer, to avoid the waste of resources.

Working principle of milling machine

Pavement milling machine is one of the main types of asphalt pavement maintenance and construction machinery. One of the main equipment for asphalt concrete pavement maintenance and construction is mainly used for the excavation and renovation of asphalt concrete surface layers such as highways, urban roads, airports, freight yards, etc. It can also be used to remove defects such as pavement embossment, oil waves, reticulation, rutting, etc. It can also be used to excavate pavement pits and grooves, and milled cement pavement roughness. Milling the damaged old pavement with a road milling machine, and then laying a new surface layer is one of the most economical modern maintenance methods. Because of its high efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good mobility, milling of old materials can be directly recycled, etc., it is widely used in urban municipal roads and highway maintenance projects. main structure and working principle The general milling machine is composed of engine, frame, milling rotor, milling depth adjustment device, hydraulic components, aggregate conveying device, steering system and braking system. The milling rotor is the main working part of the milling machine. It is composed of the milling rotor shaft, the cutter seat and the cutter head. It directly contacts with the road and achieves the purpose of milling through its high-speed rotating milling cutter. The milling machine is equipped with an automatic leveling device, which uses the side cover of the milling rotor as the milling reference surface and controls two positioning hydraulic cylinders to keep the given milling depth constant; Its hydraulic system is used to drive the milling rotor to rotate, the whole machine to walk, auxiliary device work, etc. It is generally a closed hydraulic system with multiple pumps independent of each other, which does not interfere with each other and has high reliability when working. Some milling machines are equipped with inclination adjusters as required to control the inclination of the rotor. Generally, large milling machines have an aggregate conveying device composed of a conveyor belt and a collector, which can concentrate and transfer the milled bulk material to a random walking vehicle. The height of the conveying arm can be adjusted and can swing left and right to adjust the unloading position. When the specifications and models of the milling machine are different, their structure and layout are slightly different, but the basic working principle is the same or similar. The route of power transmission of milling machine: engine → hydraulic pump → hydraulic motor, hydraulic cylinder → working device.

Metengqi Floor Grinding Application Plan

After grinding and curing treatment, the factory floor has transformed—no longer dusty or sandy, with cracks and a dull, lackluster appearance—but now clean, dust-free, highly resistant to compression and abrasion, brilliantly reflective like a mirror, and incredibly easy to maintain. The dramatic difference between the treated and untreated areas is truly remarkable.
