Operators of concrete pump trucks must receive special training, be familiar with the mechanical performance of the pump trucks, master the operation methods and precautions of the pump trucks, earnestly perform the safety responsibilities of this position in production, and abide by the relevant safety regulations on site.

2 When conveying concrete with a concrete pump, the use and operation procedures shall be observed. The pipe joint and safety valve must be intact, and the pipe rack must be firm and separated from the structural formwork of the pumping part. Try to send it with water before transportation, relieve pressure during maintenance and try to send it after maintenance.

3 When the concrete used has admixture, the personnel mixed with admixture must be careful to prevent corrosion damage.

4 The parking place of the concrete pump truck should be hardened, the parking should be stable and firm, and the drainage facilities should be good to prevent collapse.

5 Before taking over the delivery pipe of the concrete pump truck, it must be carefully checked. Whether there are cracks, leakage, serious wear of pipe body, joint damage, etc. , should be repaired or shut down, so as to avoid accidents under greater pressure when pumping concrete.

⑥ The connection and erection of pump pipes must be reliable and firm. When suspended, steel pipes must be bent. In order to prevent swinging during pumping, anchor bolts can be used for reinforcement.

7 The connection of the conveying pipe of the concrete pump truck must use intact special clips, and there should be spare clips and wearing parts during construction.

8 When pumping concrete, people are not allowed to stand on both sides of the conduit 1 m to prevent the conduit from swinging and hurting people; No one is allowed to stand within 30 meters before the catheter exits, in case there is air in the pump, and the aggregate pumped out under high pressure may hurt people.

9. When installing and removing the conduit on the wall, the operator must abide by the safety requirements of aerial work and fasten the safety belt (rope); After installation, the conduit must be firmly connected with the wall to prevent toppling.

10 when installing and disassembling the pump pipe, the labor force should be sufficient, and it is not allowed to connect and disassemble the pipe; When the concrete needs to be pumped by water pressure after delivery, the connection of the water pressure plug should be rapid and accurate, and the personnel in the warehouse should pay attention to the water spraying at the discharge port to pour down the construction personnel.

1 1 The conduit shall not be dismantled at will, and the principle of top-down, back and forth shall be followed, and the dismantled conduit shall not be directly thrown from a height; After the catheter is removed, it must be placed on a flat site, and it shall not be piled up on the bent frame at will.

12 pump pipe must be hoisted to a flat site, washed clean, stacked smoothly and inspected. If it is damaged, it must be repaired in time.

13 During the operation of the pump truck, full-time personnel should be arranged to regularly inspect whether the catheter is loose and handle it at any time, and check the stability of the fixed bent and bracket of the catheter and whether there is obvious damage to the catheter.

14 before the operation of concrete pump truck, there must be perfect communication means at the pump truck site and in the concrete construction warehouse, so that the construction can be carried out safely.
