While doing a good job in road maintenance, we should also maintain the road construction machines, which can prolong the service life of the machines. What are the maintenance methods for the cold regenerator?

合理的使用瀝青設(shè)備，使其潛力限度地發(fā)揮，是公路機械化施工企業(yè)之所求，而保養(yǎng)和維修是程度發(fā)揮機械效益的必要前提。近年來，我單位在公路機械化施工中，按照“使用和保養(yǎng)并重”的原則進行管理，改變了以前施工中只注重機械使用，不注重機械保養(yǎng)，很多易于發(fā)現(xiàn)的問題被忽略，結(jié)果使有些設(shè)備的小問題變成大故障，有些甚提前報廢。這不僅大大增加了機械維修成本，而且延誤了施工，有的甚造成工程質(zhì)量問題。針對這跟著城市發(fā)展速度的加快，各地都在大規(guī)模的拆遷和修理路面，路面修理就要用到路面冷再生機，大家一起來了解一下吧！

Rational use of asphalt equipment to give full play to its potential is the requirement of highway mechanized construction enterprises, and maintenance and repair are the necessary premise to give full play to mechanical benefits. In recent years, our company has managed in accordance with the principle of "paying equal attention to use and maintenance" in highway mechanized construction, which has changed the previous construction that only paid attention to the use of machinery and did not pay attention to the maintenance of machinery, and many easily found problems have been ignored. As a result, some small problems of equipment have become major faults, and some even scrapped in advance. This not only greatly increases the cost of mechanical maintenance, but also delays the construction, and some even cause engineering quality problems. In view of this, with the acceleration of urban development, large-scale demolition and pavement repair are being carried out all over the country. Pavement cold recycling machine is required for pavement repair. Let's have a look!

一般來說，路面長時間經(jīng)受重型交通，會導(dǎo)致路基損壞。為了這種損壞，需要對整個路面進行結(jié)構(gòu)性修理。路面冷再生機將銑刨料全部進行從頭使用，加之其經(jīng)濟的處理方式，使得采用泡沫瀝青進行冷再生施工成為一種開創(chuàng)性解決方案，到達而經(jīng)濟的效果。

Generally speaking, the pavement will be damaged by heavy traffic for a long time. In order to eliminate this damage, the whole pavement needs to be structurally repaired. The road cold recycling machine has used all kinds of milling materials from scratch. Combined with its economic processing mode, the cold recycling construction of foamed asphalt has become a pioneering solution to achieve environmental protection and economic effect.

路面冷再生機的組成和作業(yè)原理

Composition and working principle of pavement cold regenerator

組成：路面冷再生機是瀝青路面冷再生施工中的首要設(shè)備，一般由動力體系、傳動體系、作業(yè)設(shè)備、噴灑體系和操作操控體系組成。

Composition: pavement cold recycling machine is the primary equipment in asphalt pavement cold recycling construction. It is generally composed of power system, transmission system, operation equipment, spraying system and operation and control system.

作業(yè)原理：路面冷再生機向前行進時，轉(zhuǎn)子向上旋轉(zhuǎn)銑刨原路面資料，同時，水經(jīng)過軟管從路面冷再生機銜接的水車中輸送過來，并在路面冷再生機的攪拌倉中噴灑。水的輸送量經(jīng)過微處理器操控的泵送體系操控，以到達需要的含水量。銑刨轉(zhuǎn)子將水與銑刨料充沛攪拌。液體穩(wěn)定劑，例如熱瀝青可經(jīng)過專門規(guī)劃的噴灑嘴被噴灑到攪拌腔；粉狀穩(wěn)定劑如水泥需按規(guī)劃增加量事先灑布在路面冷再生機前的路面上，路面冷再生機將粉狀穩(wěn)定劑與再生料和水一次性攪拌。如遇再生層原級配不良的情況，可在再生前將所缺少的部分集料灑布在路面上，經(jīng)過與舊料攪拌來改善原路面資料的級配。

Operation principle: when the road surface cold regenerator moves forward, the rotor rotates upward to mill the original road surface data. At the same time, the water is transported from the water truck connected with the road surface cold regenerator through the hose and sprayed in the mixing bin of the road surface cold regenerator. The delivery volume of water is controlled by the pumping system controlled by microprocessor to reach the required water content. The milling rotor will fully mix the water with the milling material. Liquid stabilizers, such as hot asphalt, can be sprayed into the mixing chamber through specially planned spray nozzles; Powdery stabilizer such as cement shall be sprinkled on the pavement in front of the pavement cold regenerator according to the planned increase. The pavement cold regenerator will mix the powdery stabilizer with recycled materials and water at one time. If the original gradation of the recycled layer is poor, the missing part of the aggregate can be sprinkled on the pavement before regeneration, and the gradation of the original pavement data can be improved by mixing with the old material.

路面冷再生機的施工辦法在全球范圍內(nèi)已得到遍及認可，它在瀝青路面的修理方面受到了路途建設(shè)部門和修建公司越來越多的關(guān)注。種情況，我們在機械管理上制訂并確定了每班保養(yǎng)內(nèi)容，并督促實施。每月的月底進行瀝青設(shè)備強制保養(yǎng)2-3天，使很多故障在未出現(xiàn)前就被排除了。

The construction method of pavement cold recycling machine has been widely recognized all over the world. It has attracted more and more attention from road construction departments and construction companies in the repair of asphalt pavement. In this case, we formulated and determined the maintenance contents of each shift in mechanical management, and supervised the implementation. Mandatory maintenance of asphalt equipment is carried out at the end of each month for 2-3 days, so that many faults are eliminated before they appear.
