At present, concrete pumps have been widely used in concrete engineering construction. By adopting the concrete delivery method, the construction party can not only reduce costs, but also save construction time and standardize the construction site. However, some problems are inevitable during use, such as the phenomenon of flow interruption during pumping. So why does the concrete pump have flow interruption? What harm will it cause? How to solve the flow interruption phenomenon during construction? Now we briefly analyze and introduce the causes of flow interruption and the methods to solve the problem of flow interruption.

Hazards of flow interruption

01

First, it is easy to cause concrete segregation, and some concrete dehydrates into dry and hard concrete, causing pipe blockage, especially when pumping low slump concrete;

Second, the concrete pressure in the pipeline and distribution valve is released at the moment of reversal, which impacts the hydraulic system of the concrete pump, causing damage to some parts and increasing energy loss. The harm of flow interruption is particularly obvious when pumping vertically, especially to a height of more than 50m.
