1. If it is difficult to implement one method, the following methods shall be adopted to discharge the commercial concrete immediately.

2、在托轮和滚道之间放入木楔，以控制搅拌筒的旋转，一定要注意；将发动机熄火，拆松液压马达的一根高压油管，搅拌筒可自由旋转，控制搅拌筒的旋转，使维修孔转到下部，然后打开维修孔，清理出筒内商品混凝土。此时一定要注意，商品混凝土排出完毕后，恢复商品混凝土水泥搅拌运输车原状。紧急清理水泥搅拌运输车内商品混凝土是我们每个水泥搅拌运输车司机都应该会的，在水泥搅拌运输车发生故障的时候，及时清理，将损失降到低。

2. Put a wooden wedge between the supporting wheel and the raceway to control the rotation of the mixing drum. Be sure to pay attention to it; Turn off the engine, remove a high-pressure oil pipe of the hydraulic motor, the mixing drum can rotate freely, control the rotation of the mixing drum, turn the maintenance hole to the lower part, and then open the maintenance hole to clean out the commercial concrete in the drum. At this time, it must be noted that after the commercial concrete is discharged, the commercial concrete cement mixer truck shall be restored to its original state. Every driver of cement mixer truck should be able to urgently clean the commercial concrete in the cement mixer truck.
