Group two floors of the building interior structure to adapt to large-scale casting site set up of the reinforced concrete column and beam combination to strengthen the stability and the earthquake resistance of buildings. The two main characteristics of the construction column pump are small volume, light weight, high configuration, stable performance, flexible and convenient use, and pumping distance, pumping concrete to good. It is the first choice for the two construction of concrete in your room. It is very troublesome to manually pour structural columns, which not only wastes time, but also makes the work efficiency very low. Therefore, the construction period is prolonged, causing unnecessary losses for the construction units. The pouring of special concrete pump using the construction column is hundreds times more than that of the artificial pouring, and it has good continuity, fast discharging and good quality of concrete.
