In order to rush time, the heavy manual cart transportation may cause heatstroke for workers. The lowest construction environment temperature in winter is about minus 20 ℃, the castable cannot be used normally, winter construction measures need to be adopted to heat stirring water, and in order to meet the normal construction temperature of the castable, the transportation from stirring to construction is very critical, the transportation efficiency is improved, and the shortening of the transportation time is a key link for ensuring the construction quality.
