Summary
Operators and related equipment management personnel should read the instruction manual carefully, master its structural principles, use and maintenance, and relevant knowledge of pumping concrete; when using and operating concrete pumps, they should strictly follow the instruction manual. Because the operator needs a process to fully grasp the mechanical properties, the instruction manual should be provided at random.
Trailer Concrete Pumps operation process:
First of all, operators and related equipment management personnel should read the instruction manual carefully, master its structural principles, use and maintenance, and relevant knowledge of pumping concrete; when using and operating concrete pumps, they should strictly follow the instruction manual. Because the operator needs a process to fully grasp the mechanical properties, the instruction manual should be provided at random. At the same time, special operating points should be formulated according to the instruction manual to achieve effective control of some variable factors in the pumping technology, such as pump position and pipeline layout.
The ground supporting the concrete pump should be flat and solid; the whole machine needs to be placed horizontally, and it should not be inclined during work. The outriggers should be able to support the whole machine stably and be locked or fixed reliably. The location of the pump should be convenient for the concrete mixer truck to enter and exit the concrete hopper and feed the hopper. It should also be considered to be beneficial to the pumping pipe and reduce the pumping pressure loss. At the same time, it needs to be close to the pouring site, and convenient for power supply and water supply.
Piping should be performed according to the characteristics of the construction site and the concrete pouring plan. When piping design, check whether the horizontal conversion distance of the pipeline is compatible with the pumping distance of the concrete pump. When piping, shorten the length of the pipeline as much as possible, and use fewer bends and hoses. The laying of pipelines should be convenient for pipeline cleaning, troubleshooting and disassembly. When the new pipe and the old pipe are mixed, the new pipe should be arranged at a place with a higher pumping pressure. During the piping process, a simple pipe layout diagram should be drawn to list the specifications and quantities of various fittings, pipe clamps, bends and hoses, and provide a list.
When vertical upward piping is needed, as the height increases, ie, the potential energy increases, there is a tendency for the concrete to flow back. Therefore, a certain length of horizontal pipeline should be laid between the concrete pump and the vertical piping to ensure sufficient resistance to prevent the concrete from flowing back. When pumping concrete for high-rise buildings, pipes need to be piped up vertically. At this time, the length of the ground horizontal pipe should not be less than 1/4 of the length of the vertical pipe. If, due to site constraints, the water pipe of the required length cannot be placed, a bent pipe or hose can be used instead.
