在灌注法和表面处理法进行施工时,除了了大型自动的沥青洒布车喷洒外还有相当一部分地区、相当面积的路面仍用小型喷油车进行施工,尤其是对路面的修补所占比重更大。无论采用那种形式的洒布,液体沥青最终是由喷嘴喷岀的,喷嘴的好坏直接影响着路面的修筑质量。因此,要选择并正确使用喷嘴。下面仅就国内普遍采用的涡旋式沥青喷嘴的使用做一简单的介绍,以期引起人们的重视。所谓涡旋式沥青喷嘴就是液态热沥青在喷头体内产生旋转而后通过喷油孔喷出。它的好
In the perfusion method and surface treatment method for construction, in addition to large-scale automatic asphalt spraying vehicle there is a considerable part of the area, a considerable area of the road is still small jet fuel truck construction, especially the proportion of the repair of the road Bigger Regardless of the type of sprinkle, the liquid asphalt is ultimately sprayed by the nozzle, the nozzle directly affects the quality of the construction of the road. Therefore, choose and use the nozzle correctly. The following is only a general introduction of the domestic use of spiral asphalt nozzle to make a brief introduction, with a view to cause people’s attention. The so-called vortex asphalt nozzle is the liquid hot asphalt produced in the nozzle body rotation and then spray through the injection hole. its advantage
