Concrete pumps are among the most important equipment in the construction industry. They are used to transfer and pour liquid concrete for the best results. Pouring liquid concrete is definitely the most important task in most projects and concrete pumps are used to complete them in the most effective and clean manner. When they are working smoothly, concrete pumps will help to speed up the construction process and make the job look great.
It is always nice to see concrete pumps working without any problem. In reality, however, there are times the machines run into problems. Obstructions in the pump lines are among the commonest problems experienced during concrete pumping. Many times, obstructions lead to costly delays and throw a project behind schedule when they are not rectified in time. It is better to avoid them entirely. To be able to avoid concrete pump blockages, you need to understand the possible causes and take measures to eliminate them. Here, we will briefly discuss five possible causes of concrete pump blockages:
Problem with the Concrete Mix
This is the cause of most cases of pump blockage. When there is an issue with the mix in the form of the concrete not retaining enough water, blockage is inevitable. This can be caused by poor materials like poorly graded sand and inexperience of individuals carrying out the mixing. There can also be mix issue when concrete pumping is delayed for a long time and the mix sets too hard. It will become stiff and difficult to pump.
There are certain operator errors that can lead to blockages. Careless hose handling, for instance, can impede the flow of the liquid concrete and cause blockages. It is highly recommended that only skilled and experienced operators handle concrete pumping.
Issues with the pipelines can quickly cause concrete pump blockages. Such issues can result when the capacity of the concrete pump and the produced horsepower are not sufficient to handle the task at hand. Coupling large-diameter hose with a narrower hose will also affect the flow of the concrete through the pipeline and this will result to blockage.
The Use of Poor Quality Materials
It is important that the concrete to be pumped is of the right quality. When the concrete is not suitable for pumping as a result of poor quality materials, issues like blockages are inevitable. The inclusion of sub-standard mortar in the mix and the improper selection of additives can meaningfully increase the chances of blockages.
Poor Maintenance of Pipelines
Every aspect of the concrete pump needs to be properly maintained. When there is negligence of any kind, issues will arise. The pipelines need to be properly cleaned on a regular basis. It is also important that worn gaskets, couplings, and weld collars be replaced as soon as possible.
Preventing concrete blockages is a lot easier than fixing them every now and then. Knowing the commonest possible causes of the problem, you have to take the necessary steps to prevent concrete pump blockages.Pumps Concrete
