我们在使用混凝土自上料搅拌车的时候难免会出现一些问题，若是混凝土自上料搅拌车堵管了应该怎样处理呢？下面就是混凝土自上料搅拌车厂家为大家整理的方法。

When we use the concrete self-feeding mixer truck, we will inevitably encounter some problems. What should we do if the concrete self-feeding mixer truck is blocked? The following is how the manufacturer of the concrete self-loading mixer truck sorted it out for you.

正常情况下，混凝土在泵送管道形成柱状流体，呈悬浮状态流动。流体表面包有一层水泥浆，水泥浆层作为一种润滑剂与管壁接触，骨料之间基本上不产生相对运动。当粗骨料中的某些骨料运动受阻，后面的骨料运动速度因受影响而渐渐滞缓，致使管道内粗骨料形成集结，支撑粗骨料的砂浆被挤走，余下来的间隙由小骨料填补。这样，骨料密度增大，使该段管道内集合物沿管道径向膨胀，水泥浆润滑层被破坏，运动阻力增大，速度变慢，直运动停止而产生堵塞。

Under normal conditions, the concrete forms a columnar fluid in the center of the pumping pipeline and flows in a suspended state. There is a layer of cement slurry on the surface of the fluid. As a lubricant, the cement slurry layer contacts the pipe wall, and there is basically no relative movement between the aggregates. When the movement of some aggregates in the coarse aggregate is blocked, the movement speed of the subsequent aggregates will gradually slow down due to the impact, resulting in the formation of aggregates in the pipeline, the mortar supporting the coarse aggregate is squeezed out, and the remaining gap is filled by small aggregates. In this way, the aggregate density increases, which makes the aggregates in the pipeline expand radially along the pipeline, the cement slurry lubrication layer is damaged, the movement resistance increases, and the speed slows down until the movement stops, resulting in blockage.
