路面冷再生机的组成和工作原理!

来源:http://www.sddhfjx.com/ 日期:2020-08-29
  随着城市化进程的加快,全国各地都开始大规模的拆迁和维修路面,路面维修就要用到路面冷再生机,大家一起来了解一下吧!
  With the acceleration of urbanization process, large-scale demolition and maintenance of the road surface have been started all over the country. The pavement maintenance needs to use the cold recycling machine. Let's learn about it!
  一般来说,长期经受重型交通的路面会出现路基损坏的情况。为了消除这种损坏,需要对整个路面进行结构性维修。路面冷再生机租赁将铣刨料全部进行重新利用,加之其经济的处理方式,使得采用泡沫沥青进行冷再生施工成为一种开创性解决方案,终达到环保而经济的作用。
  Generally speaking, the roadbed will be damaged when the pavement is subjected to heavy traffic for a long time. In order to eliminate this damage, it is necessary to carry out structural maintenance on the whole pavement. The road cold recycling machine reuses all the milling materials, and its economic treatment mode makes the cold recycling construction of foamed asphalt become a pioneering solution, and finally achieves the environmental protection and economic role.

  路面冷再生机的组成和工作原理
  Composition and working principle of pavement cold recycling machine
  组成:路面冷再生机是沥青路面冷再生施工中的主要设备,一般由 动力系统、传动系统、工作装置、喷洒系统和操纵控制系统组成。
  Composition: pavement cold recycling machine is the main equipment in asphalt pavement cold recycling construction, which is generally composed of power system, transmission system, working device, spraying system and control system.
  工作原理:路面冷再生机向前行进时,转子向上旋转铣刨原路面材料,同时, 水通过软管从路面冷再生机连接的水车中输送过来,并在路面冷再生机的拌和仓中喷洒。水的输送量通过微处理器控制的泵送系统准确控制,以达到需要的含水量。铣刨转子将水与铣刨料充分拌和。液体稳定剂,例如热沥青 (冷再生机自带泡沫沥青发泡装置,可将热沥青加热到160- 180 °C,与少量水混合发泡)可通过专门设计的喷洒嘴被喷洒到拌和腔;粉状稳定剂如水泥需按设计添加量事先洒布在路面冷再生机前的路面上,路面冷再生机将粉状稳定剂与再生料和水一次性拌和。如遇再生层原级配不良的情况,可在再生前将所缺少的部分集料洒布在 路面上,通过与旧料拌和来改善原路面材料的级配。
  Working principle: when the road surface cold recycling machine moves forward, the rotor rotates upward to mill the raw road materials. At the same time, water is transported from the water truck connected with the road cold recycling machine through the hose, and is sprayed in the mixing bin of the road cold recycling machine. The water delivery capacity is accurately controlled by the microprocessor controlled pumping system to achieve the required water content. The milling rotor fully mixes water and milling material. Liquid stabilizer, such as hot asphalt (cold recycling machine) with foam asphalt foaming device, can heat asphalt to 160-180. (C, mixed with a small amount of water) can be sprayed into the mixing chamber through a specially designed spray nozzle; the powder stabilizer such as cement should be sprayed on the road surface in front of the pavement cold recycling machine according to the design amount, and the powder stabilizer is mixed with recycled materials and water at one time. If the original gradation of the recycled layer is poor, the missing aggregate can be spread on the pavement before regeneration, and the gradation of the raw pavement material can be improved by mixing with the old material.
