冷再生機施工有沒有地域和限制呢?

冷再生機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。據測算,若推廣使用,一個地級市應配置3-5臺。作為歐美發(fā)達地區(qū)已得到成熟應用的機型的,在國內保有量卻如此地低,原因有多方面,進口機型昂貴的價格應該是主要原因之一。
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.
冷再生租賃機的工作裝置是安裝有大量專用銑刨刀的銑刨拌和轉子。機器在舊路面上沿工作面行駛,轉子下降到設定深度,高速旋轉,銑刨并破碎拌和原路面材料(包括面層和基層),同時噴水系統(tǒng)根據行駛速度及銑刨深度,從伴隨的水車中抽水,向工作裝置罩殼內自動噴灑定量的水。
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(冷再生機可選配乳化瀝青噴灑裝置)可通過專門設計的噴嘴將乳化瀝青噴灑到工作裝置罩殼內;粉狀穩(wěn)定劑,如水泥,可按設計添加量事先撒布在再生機工作面上,再生機將粉狀穩(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.
就地冷再生技術不僅適用于高等級公路的維修與改造,也適用于一般道路及鄉(xiāng)間公路的維修與改造。此技術在上世紀五十年代開始在歐美等國家得到應用,目前已是發(fā)達國家已獲得較為普遍的應用,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年從國外引進第一臺路面冷再生機后,近幾年來,就地冷再生技術在我國受到了業(yè)內人士普遍的關注與認同,推廣普及速度很快,例如遼寧、吉林及河北等地區(qū)已經應用相當普遍,并且取得了良好的社會及經濟效果。
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.
