Concrete pump pipe blockage may influence the construction progress and quality. So how should we to prevent concrete pump pipe plug, as below:
1. In pipeline installation and design, as far as possible avoid 90 °C and s-shaped curved, to reduce the pumping commodity coagulation soil resistance, prevent clogging.
2. In order to guarantee the continuity of pumping concrete operation, to ensure the quality of commodity concrete pouring, homework in the interval time should not be too long, to prevent clogging. If for some reason interval for a long time, you should start every 5 ~ 10 min or so times pump or reverse and forward pump several times, to prevent clogging.
3. Pumping concrete products to pumping concrete products in strict accordance with the provisions of mixture ratio design, strict control of slump.
4. Choose the aggregate particle size must meet the requirements, should not be more than conveying pipe diameter of a quarter.To arm posture before
5. Pumping concrete products pipeline lubrication method has two kinds:
A: Traditional methods: with water lubrication tube first, then send a certain amount of mortar, and then pumping concrete products, in order to prevent clogging.
B: Scientific method: first use concrete pump special lubrication oil to lubrication piping, get through after can start pumping concrete products. This method operation is simple, the cost is very low. Now more large-scale industry, commodity concrete, arm posture pump truck leasing company etc.
6. In the hot summer, should use wet straw bag cover pipe, prevent in the process of pumping, commercial concrete falling too fast and produce wall tube.Above is a concrete pump pipe blockage prevention measures, hope to be of service, reduce the concrete pump pipe blockage accident.
