The fine stone concrete pump is a special type of concrete pump. This concrete pump is widely used in floor heating projects and floor construction, so it is welcomed by the majority of construction parties. So on the construction site, what are the pumping requirements of the fine stone concrete pump? Now let’s take a closer look.

(1) What matters should be paid attention to when entering coarse and fine aggregates?

Coarse aggregate should mainly control its particle size, gradation, grain shape, stone powder content, and mud content. Each vehicle shall undergo a macro inspection, and shall not be unloaded if it is unqualified; in addition, various indicators shall be inspected in batches in accordance with the requirements of the regulations. Fine aggregate should be controlled fineness modulus, mud content

What preparations need to be made to improve the working efficiency of the wet spray machine

In order to ensure the quality of wet spray and improve the efficiency of the wet spray machine, the preparations need to be done before the wet spray machine starts. What kind of preparations need to be done? Next, the author will discuss it for everyone.

A small loader is a heavy-duty mechanical equipment that is often used in construction projects, and it is also one of our more common equipment on the market. The service life and work efficiency of the loader are closely related to the management method of the enterprise. If we are negligent in the maintenance and management of the loader when working with it, it is likely to cause more damage to the equipment in the later period. With the increase in loss,

Shandong loader is one of the more commonly used equipment in construction engineering. The main application range is in road construction and building construction. Sometimes it is also used in hydropower construction, even port construction and mine construction. It can be applied in all aspects. The main work content of this equipment is to load some relatively scattered materials, such as soil or sand. Of course, it can also be used for light excavation operations.

When using a wet spraying machine, starting is a step. Only a successful start can be used to enter the normal wet spraying process. Therefore, in order to ensure that the concrete wet spraying machine starts successfully, it must be carefully checked after it is started. Let me discuss it for everyone.

The traditional spraying support technology of underground space mainly relies on manual operation of spraying machine construction, spraying a certain thickness of concrete to achieve the supporting effect. In the traditional spraying environment, there are a large number of dust particles, noise pollution is also quite serious, and there is a danger of underground collapse, which poses a serious threat to the life and safety of operators in underground space construction.

For the safety of the construction personnel, the safety operation process of the wet spray manipulator is specially made: 1. It is strictly forbidden to use the manipulator as a crane or lifting platform. 2. Do not move the vehicle and operate the manipulator at the same time. After the vehicle reaches the working position, it must be fixed to prevent rolling: use the handbrake, turn off the engine, and place the driving direction joystick in the neutral position.

1. Blockage at the discharge port of the distribution valve
The discharge port is blocked, usually the pumping system is suddenly interrupted, and there is abnormal sound, the equipment has strong vibration, but there is no corresponding vibration in the pipeline.
Remedy: Pour cement slurry into the hopper, and start the pump repeatedly in forward and reverse directions to force the passage to open. If this method is not daring, you can only remove it manually

Concrete piston overall wear, partial wear, ablation wear, strain, and later maintenance methods.

Partial overall wear

1. Main features of overall wear

The radial wear of the lip part of the concrete piston of the concrete pump accessories is basically the same, and the wear marks are relatively uniform.
