Step one: Flush the pipeline with clean water
Since the ground pump pipeline is often fixed at the construction site, debris may appear in the pipeline. It is recommended to pump clean water first to flush the debris in the pipeline. , after flushing the pipe, try not to leave excess water in the pipe to avoid diluting the lubrication solution and failing to achieve the best lubrication effect.
Step 2: Check whether the pipe is intact
After flushing the pipe with clean water, check manually whether there is any leakage at the pump pipe connection as much as possible. If there is leakage, it needs to be repaired or replaced. part. If the water leakage is serious, slurry will leak out when pumping concrete and cause pipe blockage. We hope to nip the pipe blockage problem in the bud
Step 3: Prepare pipe lubricant
In Start preparing the lubricant solution ten minutes before the concrete arrives at the construction site. You can mix it directly in the hopper (if the hopper leaks and cannot be repaired, you need to prepare other containers). Prepare water and lubricant according to the table below according to the length of the pump pipe. After preparing the water, tear open the packaging bag and slowly pour the moisturizer powder into the water. Remember not to pour the moisturizer powder into the water quickly, as this will cause insufficient dissolution. When adding the lubricating agent powder, stir with a stick or turn on the reverse pump at the same time until the lubricating agent solution forms a viscous state. When the lubricating agent solution forms a viscous state, the lubricating agent solution has been prepared.
Step 4: Pump the lubricating agent to achieve lubricating
When the concrete arrives at the construction site, first turn on the pump and pump the lubricating solution. When the lubricating solution is used, pump the lubricant quickly. When finished, the concrete is slowly discharged along the inner wall of the hopper and pumped continuously. The first lubrication solution discharged from the pump pipe outlet must be discharged outside the formwork and cannot be poured directly into the concrete structure. Normal pouring can be started after observing with the naked eye that the lubrication solution has been drained out. Since the lubrication solution is relatively slippery, you must not step on it during the construction process to avoid accidents. The lubrication solution will naturally evaporate after 72 hours.
Concrete Pumping Tips
It is particularly critical to control the pumping speed of the first truck of concrete. At the beginning, the pipe resistance is large, and the operator cannot blindly try to be fast. Haste makes waste. . At this time, the pumping speed should be constant. After the pumping is normal, the pumping speed can be increased appropriately. When there are signs of pipe blockage or the slump of a certain truck of concrete is small, pumping should be done at a low speed to minimize the probability of pipe blockage.
