就地冷再生常用的一种施工方案如何

来源:http://www.tclqgc.com/ 日期:2022-09-17 发布人:guanli
根据原有道路结构和新设计方案的不同,就地冷再生可以组合出多种施工方案!以水泥为添加料对沥青路面进行就地冷再生是常用的一种方案。下面冷再生机租赁厂家为您讲讲。
According to the difference between the original road structure and the new design scheme, a variety of construction schemes can be combined by cold recycling in place! In situ cold recycling of asphalt pavement with cement as additive is a common scheme. Let's talk about the cold regenerator rental manufacturer.
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。同时还要加入适量的水。
When the cement is used for on-site cold regeneration, the additive is mainly cement, and the normal amount of cement is between 2% and 5% by weight. If the amount of cement is too much, it is easy to make the regeneration layer brittle. At the same time, add some water.
水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,是通过冷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冷再生机的拌和仓中。
There are two ways to add cement. One is to use manual or special machinery to pre spread cement on the pavement to be recycled. At this time, the method of adding water is to transfer it from the water truck working with the shift to the mixing bin of the cold regenerator through the microcomputer control system equipped on the cold 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,再通过冷再生机上的控制系统将其输送到冷再生机的拌和仓中。
Another method is to use cement slurry mixer truck to mix the cement and water to be added into cement slurry, and then transport it to the mixing bin of the cold recycling machine through the control system on the cold recycling machine.
这种方法的优点就是在控制用量方面非常方便。因为在施工中冷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,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。
The advantage of this method is that it is very convenient to control the dosage. During construction, the cold recycling machine can only complete the milling of the whole pavement in one operation section by several working trips, and the rolling of the recycling layer can only be carried out after the completion of all construction procedures in the whole operation section, which results in a large difference in the time interval between the first milling pavement and the later milling pavement and the rolling.
实际上各种施工方案的工作原理都是一样,区别是掺入材料的不同,加入的方法也有所不同。以上的方法希望能够帮助到您,您还有问题就来我们网站http://www.tclqgc.com咨询吧。
In fact, the working principles of various construction schemes are the same. The difference is that the materials are mixed in different ways. I hope the above methods can help you. If you have any questions, please come to our website http://www.tclqgc.com Consult.
