冷再生机施工有没有地域和限制呢?

来源:https://www.sddhfjx.com/ 日期:2022-03-11
冷再生机施工有没有地域限制呢?全国各地的沥再路面均可使用此种工艺。据测算,若推广使用,一个地级市应配置3-5台。作为欧美发达地区已得到成熟应用的机型的,在国内保有量却如此地低,原因有多方面,进口机型昂贵的价格应该是主要原因之一。
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.
冷再生租赁机的工作装置是安装有大量专用铣刨刀的铣刨拌和转子。机器在旧路面上沿工作面行驶,转子下降到设定深度,高速旋转,铣刨并破碎拌和原路面材料(包括面层和基层),同时喷水系统根据行驶速度及铣刨深度,从伴随的水车中抽水,向工作装置罩壳内自动喷洒定量的水。
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.
水的输送量通过微处理器控制的泵送系统精确控制。铣刨转子将水与铣刨料充分拌和均匀。
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.
液体稳定剂,例如热沥青(冷再生机可选配乳化沥青喷洒装置)可通过专门设计的喷嘴将乳化沥青喷洒到工作装置罩壳内;粉状稳定剂,如水泥,可按设计添加量事先撒布在再生机工作面上,再生机将粉状稳定剂与路面和水一次性破碎并拌和均匀。
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.
就地冷再生技术不仅适用于高等级公路的维修与改造,也适用于一般道路及乡间公路的维修与改造。此技术在上世纪五十年代开始在欧美等国家得到应用,目前已是发达国家已获得较为普遍的应用,并常常作为路面维修的首选方案。
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.
自从我国在1998年从国外引进第一台路面冷再生机后,近几年来,就地冷再生技术在我国受到了业内人士普遍的关注与认同,推广普及速度很快,例如辽宁、吉林及河北等地区已经应用相当普遍,并且取得了良好的社会及经济效果。
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.
