Concrete pump truck block pipe you need to do this

Concrete pump truck anti-blocking pipe you need to do this:

Regardless of the size of the site, prior to the construction of the corresponding planning and design, concrete pump truck installation and design of the pipeline, as far as possible to avoid 90° and S bend. Try not to use the pump pipe with obvious pits, in order to reduce the resistance of pumping concrete, prevent blocking. Usually, if the pump is often switched between high and low pressure, the hopper of the pump truck needs to be raised about 20cm, so as to increase the hopper product, so as to ensure that the concrete will not flow out.

Because the 700 type of forced mixer in unloading, it is better to finish unloading, so that the flow into the hopper of the concrete force is evenly proportioned. At the same time, in order to ensure the continuity of pumping concrete and ensure the quality of concrete pouring, the interval time in the operation should not be too long to prevent clogging.

In addition to the reasonable use of the mixer, the pump tube should be checked regularly. If the wear degree of the pump tube in one direction is large, the tube should be switched to the other position in time. If the thickness of the pump tube is too thin, the new tube should be replaced in time to prevent the pump tube from exploding in the process of work or plugging caused by the replacement of the pump tube for a long time. Because one of the reasons for blocking the pipe is the long interval between stops, so the construction personnel should start a pump every 20 minutes or so or several times of reverse and positive pump, if necessary, the circulation pump to prevent blockage.

If the unloading, the back of the concrete stone is more, especially when the concrete slump is larger, more attention should be paid to, if it is a large volume of mixing and machine, can do a storage hopper in advance, to ensure continuous feeding.
