Leakage caused by imperfect sealing of the pipeline will affect the quality of concrete pouring on the one hand, and reduce the slump of the concrete and the loss of pumping pressure on the other hand, which will lead to the blockage of the pipeline. The pipeline joint is not tightly sealed, the pipe clamp is loose or the sealing ring is damaged, causing slurry leakage.

The pumped concrete should be designed in strict accordance with the regulations, the slump should be strictly controlled, and the following principles should be followed. (1) The ratio of the large particle size of the coarse aggregate to the diameter of the conveying pipe should be: when the pumping height is below 50 m, the

The cleaning of the concrete placing boom machine is very important. It is inevitable that some impurities will be left on the concrete placing boom machine after use, which will cause the concrete placing machine to rust. It’s easy to get started when it’s time, and the concrete placing boom machine also needs to be cleaned.

Concrete spreaders are divided into manual concrete placing booms and hydraulic concrete placing booms. According to different pouring environments and individual requirements, develop mobile hydraulic concrete placing booms, walking hydraulic placing booms, independent hydraulic placing booms, elevator shaft climbing hydraulic concrete placing booms, floor slabs Jack-up hydraulic distributing placing boom machine, horizontal hydraulic distributing machineplacing booms, etc.

(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

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.

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,

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.
