What is the arrangement of the concrete pump pipe?
As an indispensable conveying system in modern building construction, the reasonable arrangement of concrete pump pipe is directly related to concrete pumping efficiency, construction quality and project safety. As a professional supplier of concrete pump pipe fittings, we are well aware of the importance of scientific and reasonable pipe arrangement for the whole construction process.
Basic principles of concrete pump pipe layout
Concrete pump pipe arrangement needs to follow a few basic principles: first, the pipeline should be as short as possible to shorten the conveying distance, reduce the number of elbows, in order to reduce the pumping resistance; second, the pipeline arrangement should maintain a relatively stable slope, to avoid the emergence of the “hump” or “depression”, to prevent the concrete in the pipeline to produce segregation; finally, the pipeline must be fixed firmly, to prevent displacement or vibration in the process of high-pressure pumping. Reasonable arrangement can significantly reduce the risk of pipe blockage and improve pumping efficiency by more than 30%.
Technical points of horizontal and vertical arrangement
In horizontal arrangement, the pipe should be laid smoothly along the ground or support, with a fixing point set every 2-3 meters, and additional reinforcement should be provided at the bend. Vertical arrangement is more complicated, and it is necessary to set up a firm support frame at each floor to withstand the huge impact force when pumping. It is worth noting that, in the vertical upward pumping, the bottom horizontal section length should not be less than 1/4 of the vertical height, this “horizontal buffer section” can effectively reduce the impact of the falling concrete to prevent segregation phenomenon.
Piping arrangement strategy for special construction environment
For ultra-high-rise buildings or long-distance pumping, relay pump relay technology can be used, and the piping system can be arranged in sections. In narrow construction sites, the combination of 45° and 90° bends can be used flexibly to optimize the piping direction under space-constrained conditions. In winter construction, it is also necessary to consider thermal insulation measures for the pipeline to prevent the concrete temperature from dropping too quickly to affect the fluidity.
As a professional pump pipe supplier, we suggest that the construction party fully understand the site conditions before arranging the pipes, choose the suitable pipe diameter and wall thickness, use high-quality fittings and seals, and regularly check the wear of the pipes. Scientific and reasonable arrangement of pumping pipe can not only improve construction efficiency, but also protect the quality of the project and reduce construction costs, which is an important part of modern building construction that cannot be ignored.
