In general, if strong acid and strong alkali are used to corrode, the car tank may be damaged, and the cost is high, requiring a lot of acid and alkali. Now there is a special cleaning industry, with a cost of about 5000. It needs to be hit with an air cannon. One person should go in and clean up the solidified concrete. Therefore, we should pay attention to the cleaning after use and the shutdown time control during use. The more timely the concrete mixing tank is stopped, the easier it is to clean up the concrete.
In addition, it should be noted that in this case, the vehicle damage insurance will not be compensated. According to the provisions of vehicle insurance: the damage of the vehicle caused by the movement and collision of its own goods or objects in the vehicle belongs to the scope of liability exemption. According to the principle of proximate cause of insurance, the direct cause of tank loss is tank shutdown and cement solidification, rather than tank loss caused by accident, so it is not compensated.
In other words, if the tank stops and the concrete solidifies, the insurance company cannot be required to compensate.
If the hydraulic system of the concrete mixer fails during operation, and there is no high-pressure oil pipe and emergency mixer nearby, the concrete in the mixing drum will solidify in the tank over time. Once the concrete solidifies, the tank will basically be scrapped.
So is there no room for maneuver? There is no absolute in the world. When the concrete mixer meets this special situation, if you don't want to replace the tank, you can ask professional cleaning personnel to break and dismantle the tank. The method is to cut a large hole for one access with oxygen welding, then use the breaking and dismantling machinery to break and dismantle it bit by bit, and finally enter the tank to break and dismantle it bit by bit until the concrete is cleaned. Finally, seal the cutting opening of the tank body with electric welding.
