Concrete pump truck blockage treatment method:

The popularity of concrete pump trucks liberates the labor force of the public and improves the work efficiency of construction units, but it also strengthens the dependence of construction on concrete pump trucks. Once the pump truck fails, it will directly affect the construction progress, and Pipe blockage is a common fault of concrete pump trucks and needs to be dealt with in time.

1. Blockage at the outlet of the distribution valve

Judgment method: If the pumping system is suddenly interrupted, no abnormal noise is found, the equipment has strong vibration, and there is no corresponding vibration in the pipeline, it is judged that the outlet of the distribution valve is blocked.

Remedy: Pour cement slurry into the hopper, stop when it is enough, and force the passage to open several times. If this method is ineffective, it can only be removed manually, the connecting pipe is removed, and the debris in the valve is removed.

2. Blockage of the feed outlet

Judgment method: During the construction process, the hydraulic system of the pumping action machine is normal, there is no abnormal sound and vibration, there is large aggregate or agglomeration in the hopper, and it is found that the material mouth is stuck or arched and blocked.

Elimination method: during the construction process, the pump is operated in reverse to destroy the agglomeration, so that the commercial concrete is returned to the hopper for re-mixing, and then pumped forward. If it does not work and needs to be cleaned manually, it can be excluded.
