冷再生機(jī)施工有沒有地域限制呢?全國各地的瀝再路面均可使用此種工藝。據(jù)測(cè)算,若推廣使用,一個(gè)地級(jí)市應(yīng)配置3-5臺(tái)。作為歐美發(fā)達(dá)地區(qū)已得到成熟應(yīng)用的機(jī)型的,在國內(nèi)保有量卻如此地低,原因有多方面,進(jìn)口機(jī)型昂貴的價(jià)格應(yīng)該是主要原因之一。
Is there any regional restriction on the construction of cold regenerator? This technology can be used in asphalt pavement all over the country. It is estimated that if it is popularized, a prefecture level city should be equipped with 3-5 sets. As a mature model in developed regions in Europe and America, the domestic ownership is so low for many reasons, and the high price of imported models should be one of the main reasons.
冷再生租賃機(jī)的工作裝置是安裝有大量專用銑刨刀的銑刨拌和轉(zhuǎn)子。機(jī)器在舊路面上沿工作面行駛,轉(zhuǎn)子下降到設(shè)定深度,高速旋轉(zhuǎn),銑刨并破碎拌和原路面材料(包括面層和基層),同時(shí)噴水系統(tǒng)根據(jù)行駛速度及銑刨深度,從伴隨的水車中抽水,向工作裝置罩殼內(nèi)自動(dòng)噴灑定量的水。
The working device of the cold regeneration rental machine is a milling mixing rotor equipped with a large number of special milling cutters. The machine runs along the working face on the old road surface, the rotor drops to the set depth, rotates at high speed, grinds, breaks and mixes the raw road materials (including surface course and base course). At the same time, the water spraying system draws water from the accompanying water truck according to the driving speed and milling depth, and automatically sprays a certain amount of water into the cover of the working device.
水的輸送量通過微處理器控制的泵送系統(tǒng)精確控制。銑刨轉(zhuǎn)子將水與銑刨料充分拌和均勻。
The delivery volume of water is accurately controlled by the pumping system controlled by microprocessor. The milling rotor shall fully mix the water and milling materials evenly.
液體穩(wěn)定劑,例如熱瀝青(冷再生機(jī)可選配乳化瀝青噴灑裝置)可通過專門設(shè)計(jì)的噴嘴將乳化瀝青噴灑到工作裝置罩殼內(nèi);粉狀穩(wěn)定劑,如水泥,可按設(shè)計(jì)添加量事先撒布在再生機(jī)工作面上,再生機(jī)將粉狀穩(wěn)定劑與路面和水一次性破碎并拌和均勻。
Liquid stabilizers, such as hot asphalt (the cold regenerator can be equipped with emulsified asphalt spraying device), can spray emulsified asphalt into the housing of the working device through specially designed nozzles; Powdery stabilizer, such as cement, can be spread on the working face of the regenerator according to the designed addition amount. The regenerator will crush and mix the powdery stabilizer with the pavement and water at one time.
就地冷再生技術(shù)不僅適用于高等級(jí)公路的維修與改造,也適用于一般道路及鄉(xiāng)間公路的維修與改造。此技術(shù)在上世紀(jì)五十年代開始在歐美等國家得到應(yīng)用,目前已是發(fā)達(dá)國家已獲得較為普遍的應(yīng)用,并常常作為路面維修的首選方案。
In situ cold regeneration technology is not only applicable to the maintenance and reconstruction of high-grade roads, but also to the maintenance and reconstruction of general roads and rural roads. This technology has been applied in Europe, America and other countries since the 1950s. At present, it has been widely used in developed countries, and is often used as the first choice for pavement maintenance.
自從我國在1998年從國外引進(jìn)第一臺(tái)路面冷再生機(jī)后,近幾年來,就地冷再生技術(shù)在我國受到了業(yè)內(nèi)人士普遍的關(guān)注與認(rèn)同,推廣普及速度很快,例如遼寧、吉林及河北等地區(qū)已經(jīng)應(yīng)用相當(dāng)普遍,并且取得了良好的社會(huì)及經(jīng)濟(jì)效果。
Since China introduced the first pavement cold recycling machine from abroad in 1998, in recent years, the in-situ cold recycling technology has been widely concerned and recognized by people in the industry in China, and the popularization speed is very fast. For example, it has been widely used in Liaoning, Jilin and Hebei, and has achieved good social and economic results.
