Luke brand fine stone concrete pump full hydraulic control, automatic lubrication pump design, pumping head 15 meters, suitable for building floor pouring leveling, secondary structure column watering, mortar conveying. How to deal with the phenomenon that the conveying pipe is blocked during the conveying process.

Generally from cement, aggregate. Improper operation These points analyze the blockage. 1. Cement. When the amount of cement is too much, the bleeding is large, which causes segregation of concrete. When the concrete is isolated, you can choose to use fly ash or increase the amount of cement to reduce the water-cement ratio; or you can use the air-entraining or low-air-reducing water reducing agent.
2, aggregate. The sand ratio is too low and the sand is poorly graded. At this time, the sand rate can be appropriately increased (not lower than 41%), and the gradation of the sand is increased. The particle size is less than or equal to 0.3 mm, which is about 20%; 0.3-2.5 mm is about 75%; and 2.5-5.0 mm is about 5%.
3. Improper operation. The concrete supply was interrupted and the joint leaked cement slurry. This requires the construction personnel to prepare the feeding plan in advance according to the amount of pouring.
In addition to the above points, when the concrete pump is blocked, it is also possible to use a wooden hammer to knock the blocked part during the pumping-reverse pumping operation, so that the blocked aggregate can be disintegrated and the pipeline can be restored smoothly; Invalid, it is no longer possible to hit a hammer or other object that may damage the pipe.

When the location of the pipe block cannot be quickly determined or difficult to disassemble, we can choose to blow the concrete by air washing. In the case of pipe plugging, it is often necessary to wash the pipe in sections. If the pipe is divided into shorter pipe sections and can not be washed, it is necessary to remove all the pipes section by section, remove the concrete, and then rinse them with water.

When the fine stone concrete pump is blocked, it will affect the normal operation of the construction. In severe cases, it may even cause the machinery to be scrapped. This requires the construction operator to check before use, and also pay attention to keeping the conveying pipe unobstructed during use. Only the right operation will make the machine play its own value.
