What are the requirements for the selection of concrete pump tubing and the setting of the bracket?
The bracket shall be determined by calculation and, if necessary, the structure of the position shall be checked;
2 concrete coarse aggregate maximum diameter of not more than 25mm, can be used within the diameter of not less than 125mm of the pump tube; concrete coarse aggregate maximum diameter of not more than 40mm, can be used within the diameter of not less than 150mm of the pump tube;
1 concrete pump pipe should be based on the pump model, the performance of the mixture, the total output, the unit output, transport distance and coarse aggregate size to choose;
3 delivery pump pipe fittings should be tightly connected to the pipeline to the pipeline should be smooth;
4 transport pump pipe should be fixed with a bracket, the bracket should be firmly connected with the structure, transport pump tube at the stent should be encrypted.
