According to the data provided by the concrete blending terminal, summed up some experiences and lessons in the application of pumping asset concrete blocking pump, pipe plugging, I wish to aid you concrete good friends. Pump concrete is identified by uniform worldly top quality, stable high quality, quickly feeding speed, can be a continual upright and straight transport, high production performance and also labor conserving. Due to the fact that the communicating pump is delivered and also poured along the pipe, the pipeline clog is one of the most distressing thing for pumping concrete.
Concern: what is the reason for dragging the pipe to pump the concrete to the deep foundation pit? What procedures should be taken?
Answer: When the deepness of the deep structure pit surpasses 5m, the concrete mix in the likely pipe area from the ground to the bottom of the pit obtains a large descending attraction, so that the mix moves down, and also the gas goes up to the turning part as well as types gas blocking. The connecting issue can be addressed by setting 180 flexes a few meters at the lower end of the likely pipe section, or the exhaust valve can be offered at the upper end of the lower bend pipeline.
Concern: if pumping concrete is reduced mark, is not good to dozen? Because just recently linked a set of single, is the pillow, with C20, pump hand reflect a little negative, I mosted likely to the site to see discovered the pump played really hard, I ask yourself whether because of low quality concrete because less concrete dose, communication is not really couple of, plus is the cause of the great stone, rocks, so poor play?
Solution: might be your mix ratio layout is not sensible, low strength pumping concrete mix ratio style to use “double mix” mineral material, specifically blended at the same time a lot of slag powder and also powder ash, make the powder of concrete is reasonably a lot more, specifically beneficial to pumping. Via the “double combined” low stamina quality pumping concrete workability, fluidity, pumping efficiency have been enhanced, at the same time, the 28d compressive stamina of concrete can meet the layout demands and also within a reasonable variety, than average concrete cost savings, reduce expenses, and concrete is very easy to resonance, uniform, good resilience. C25 as well as C20 additionally make use of the “dual blending” technique to make the lining concrete attain far better economic benefits as well as quality effect.
If you can choose resources, the result will certainly be better, such as with reduced quality concrete, rated sand, as well as utilizing excellent admixture with concrete versatility. Adjust on the basis of resources in addition to raise the amount of concrete, there is to allow the water minimizing representative makers to think of a means, they will certainly change the preparation of decreasing the including agent according to your situation.
