Safety issues should be paid attention to in the construction of the concrete pump

  • The Putzmeister boom pump shall be placed at a distance from the edge of the foundation pit.
  • When the wind force is greater than level 6, the concrete arm Putzmeister concrete pump shall not use the placing boom. When the weather is hot, cover the pipes with something like the wet sack.
  • Pipe laying line for the horizontal pump should be reasonable. The support must be tightly fixed and reliable. The pipe joint should be sealed and reliable.
  • The size of sand and gravel, the grade of cement and the proportion should meet the requirement of concrete pump machine. When pumping, the material in the hopper should be higher than the height of the suction inlet to prevent air pollution.
  • It is strictly forbidden to install the vertical pipeline directly on the pump outlet. Horizontal pipe of not less than 10m length shall be installed at the front end of the vertical pipe erection, and reverse valve shall be installed near the pump. When laying the downward sloping pipe, the lower end should be connected with a section of horizontal pipe, whose length is at least five times of the height difference of the dip. Otherwise, the bending pipe can be adopted to increase the stress. If the inclination is large, when necessary, the upper end of the ramp should be installed exhaust valve to facilitate exhaust.
  • The stop and lock brake of pumping equipment should be used at the same time, and the tire should be wedged tightly. The water tank should be filled with clean water. There should be no sundries in the hopper. And the lubrication points should be lubricated normally.
