冷再生机具有哪些施工方式?

根据道路的原有结构,冷再生机的施工方案也不同,今天就给大家介绍一下:
According to the original structure of the road, the construction scheme of the cold regenerator is also different. Let's introduce it to you today:
在利用水泥进行就地冷再生时,外加料主要是水泥,水泥的通常用量按重量计在2%-5%之间比较合适。如果水泥的用量过多,容易使再生层变脆。为了获得良好的压实效果,同时还要加入适量的水。水
When using cement for in-situ cold regeneration, the additive is mainly cement, and the usual dosage of cement is between 2% - 5% by weight. If the amount of cement is too much, it is easy to make the recycled layer brittle. In order to obtain good compaction effect, an appropriate amount of water should be added at the same time. water
泥的加入方法有两种!一种是利用人工或专用机械将水泥预先撒布在需要再生的路面上。这时水的加入方法,是通过再生机上所配备的微机控制系统从跟班作业的运水车内输送到再生机的拌和仓中。
There are two ways to add mud! One is to use manual or special machinery to pre distribute cement on the road surface that needs regeneration. At this time, the water is added through the microcomputer control system equipped on the regenerator, which is transported from the water truck of the attendant to the mixing bin of the regenerator.
另一种方法是采用水泥稀浆搅拌输送车,将需要添加的水泥和水搅拌成水泥稀浆,再通过再生机上的控制系统将其输送到再生机的拌和仓中。
Another method is to use the cement slurry mixing truck to mix the cement and water to be added into cement slurry, and then transport it to the mixing bin of the regenerator through the control system on the regenerator.
上述两种加入方法各有利弊,预撒水泥法工艺简单, 但在施工过程中容易产生灰尘,不过这种方法有一个很大的优点,就是在控制用量方面非常方便。
The above two addition methods have their own advantages and disadvantages. The pre cement method is simple, but it is easy to produce dust in the construction process. However, this method has a great advantage, which is very convenient in controlling the dosage.
因为在施工中“ 再生机要分几个工作行程才能完成一个作业段内整幅路面的铣刨,而再生层的碾压要等到整个作业段全部施工工序完成之后才能进行
Because in the construction, the "recycling machine" can complete the milling of the whole pavement in an operation section only by dividing into several working strokes, and the rolling of the recycling layer can only be carried out after the completion of all construction processes in the whole operation section
这就形成先铣刨的路面和后铣刨的路面到碾压时所等待的时间间隔相差很多,在较热或较干燥的气候里,随着时间的拖延,先铣刨的路面水分蒸发得较多,而后铣刨的路面水分蒸发得较少。
This results in a great difference in the waiting time interval between the first milled pavement and the later milled pavement to rolling. In a hot or dry climate, with the delay of time, the water evaporation of the first milled pavement is more, and the water evaporation of the later milled pavement is less.
