We all know that there are technical requirements for the operation of the concrete mixing pump truck. Strict operation in accordance with the technical requirements will help to improve the construction efficiency and avoid risks. The following is a summary of the operation requirements of the small mixer:
1. Ensure high concentration of operators
The energy level of the operator of the small concrete mixer is very important. The operator of the small concrete mixer truck should ensure the energy concentration during the construction of the pump truck, and pay attention to the parameters of the pump truck, especially the pressure gauge data of the small concrete mixer truck. Once abnormal data of pressure gauge is found, corresponding measures shall be taken in time to prevent pipeline blockage and ensure normal construction of pump truck. If the pipeline is blocked, it shall be handled according to the specification or contact the manufacturer's after-sales personnel.
2. Select the right pumping speed
More haste, less speed. Never adjust the pump speed too fast due to construction peak period and other reasons. Special attention shall be paid to the first pumping, so when the first time is used, the resistance of all pipes is relatively large, which requires the method of low-speed pumping, and the test shall be carried out after the pumping phenomenon is normal, so as to gradually improve the pumping speed of concrete.
3. Control the amount of paint at any time
In the construction process of small concrete mixer, the operator should always pay attention to the paint in the hopper, do not let the paint lower than the mixing shaft, of course, do not let the paint in the hopper accumulate too much. This is mainly because in the process of pumping, if there is too little paint in the hopper, it will simply inhale air, resulting in the explosion of pipe blockage. So what if there are too many paints in the funnel? Too much is not conducive to the timely sorting of coarse aggregate and large aggregate, and will also lead to the outbreak of pipe blockage.
4. Deal with the problem of low slump of concrete
In the construction of small concrete mixer, the constructors must pay attention to the slump of concrete in the hopper at all times. If the slump of bucket concrete is found to be very small in the construction process, it is unable to perform normal beating, and the operator cannot greedily take the forced injection or water mixing construction method, it is easy to form a blocking pipe and affect the power construction. What would you do? The builder should loosen the bottom of the concrete mixing funnel in time.
5. Pay attention to pipeline problems
In the construction process, if the small-scale concrete mixer needs to stop, it must control the stop time, otherwise it will form concrete in the pipeline, which will bring inconvenience to the next construction and easily form the phenomenon of pipeline blockage. In addition, after the completion of construction, the small concrete mixer truck shall clean the pipeline in time, and ensure the cleanness and cleanness of the pipeline to prevent the pipeline from being used next time.
