Experts pointed out: fine aggregate concrete pump pipe during construction, to pump tube cleaning, which is an important step after pumping essential. Good cleaning method generally either cleaned pipes, and the pipe can be transported to the pouring of concrete all locations, so that not only save the amount of concrete, but also a considerable economic environment. Specifically, the step of cleaning the fine aggregate concrete pump has the following steps.
1, check the cutting ring and glasses, plates
Check the cutting ring and wear plate between the eyes, which is the key to the success of the direct kick cleaning method. If the cutting ring and the wear and tear is not serious eye plate, cutting ring and eye plate spacing <0.1 mm, and no more than one millimeter between them grooves scratch, you can use a direct kick method for cleaning.
2, short pipe cleaning method
Under normal circumstances, can be After pumping concrete pumping 0.15 ~ 0.25m \ +3 cement ratio of 1.5 or 1:2 mortar, then fill the water in the dispensing valve to start pumping, the concrete pumping pouring into place until the end of the delivery tube output until the water flows out. If the pipe is shorter, the cleaning effect is better, then the cleaning process ends.
3, long pipe cleaning method
If the pipe is longer or cleaning effect is not very good, you can open the hopper discharge doors and anti-pump, hopper and dispensing valve rinse. If pumping height up and> 20 m, you can choose with a wooden hammer percussion section at the bottom of the vertical pipe, if the percussion sound is very low, you need to bend apart, poured can accumulate large aggregates.
