就地冷再生常用的一種施工方案如何
來(lái)源：http://kqj188.com/ 日期：2022-09-17 發(fā)布人：
根據(jù)原有道路結(jié)構(gòu)和新設(shè)計(jì)方案的不同，就地冷再生可以組合出多種施工方案！以水泥為添加料對(duì)瀝青路面進(jìn)行就地冷再生是常用的一種方案。下面冷再生機(jī)租賃廠家為您講講。
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.
在利用水泥進(jìn)行就地冷再生時(shí)，外加料主要是水泥，水泥的通常用量按重量計(jì)在2%-5%之間比較合適。如果水泥的用量過(guò)多，容易使再生層變脆。同時(shí)還要加入適量的水。
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.
水泥的加入方法有兩種，一種是利用人工或?qū)Ｓ脵C(jī)械將水泥預(yù)先撒布在需要再生的路面上。這時(shí)水的加入方法，是通過(guò)冷再生機(jī)上所配備的微機(jī)控制系統(tǒng)從跟班作業(yè)的運(yùn)水車內(nèi)輸送到冷再生機(jī)的拌和倉(cāng)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.
另一種方法是采用水泥稀漿攪拌輸送車，將需要添加的水泥和水?dāng)嚢璩伤嘞{，再通過(guò)冷再生機(jī)上的控制系統(tǒng)將其輸送到冷再生機(jī)的拌和倉(cāng)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.
這種方法的優(yōu)點(diǎn)就是在控制用量方面非常方便。因?yàn)樵谑┕ぶ欣湓偕鷻C(jī)要分幾個(gè)工作行程才能完成一個(gè)作業(yè)段內(nèi)整幅路面的銑刨，而再生層的突出要等到整個(gè)作業(yè)段全部施工工序完成之后才能進(jìn)行，這就形成先銑刨的路面和后銑刨的路面到突出時(shí)所等待的時(shí)間間隔相差很多。
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.
實(shí)際上各種施工方案的工作原理都是一樣，區(qū)別是摻入材料的不同，加入的方法也有所不同。以上的方法希望能夠幫助到您，您還有問(wèn)題就來(lái)我們網(wǎng)站http://kqj188.com咨詢吧。
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://kqj188.com Consult.
