Concrete mixing plant at this stage of industry development problems

　　Under the role of construction cost, the surrounding environment restrictions and other factors, concrete mixing plant equipment in the daily use of different degrees of problems, the surrounding environment of the project, construction quality have a negative impact. The managers should pay great attention to this problem, strengthen the safety management and improve the standardization of equipment operation.

 

　　There are many villages and fish ponds around the project. The mixing plant is the basic equipment to promote the construction operation, and it adopts the form of operating subcontracting, which generally has the problems of high staff mobility, low staff quality and insufficient financial support, leading to the long-term chaotic operation and management of the mixing plant, and the concrete testing station is responsible for the quality testing of various raw materials used for mixing, but the professional quality of the staff is low, and the whole concrete Mixing station testing station of high precision talent ration is not enough, and staff in quality management awareness, professionalism and other aspects are very poor, and engineering requirements for the performance of mixed materials can be disconnected, testing work in jerry-building, improper technical control and other issues are common. In this environment, the quality of concrete can not be guaranteed, and construction safety hazards are increasing. In the concrete production process, there are also various problems related to personnel, such as cutting corners, inaccurate measurement of the amount of raw materials, etc., the quality of the concrete produced does not meet the quality of the material substandard. The lack of effective incentive mechanism concrete quality can not be guaranteed, resulting in construction quality adverse effects, fundamentally affect the quality of construction, fundamentally also adverse effects on the quality of construction.

 

　　The main building of the mixer mainly includes inclined belt motor, admixture scale, crushing scale, sand and gravel material buffer bucket, mixer and other working parts. Mixer mainframe daily maintenance and fault diagnosis, should pay attention to the inspection of the liner, observe its wear and tear, if found damaged, should be replaced immediately to prevent the concrete due to damage to the liner wear bottom plate. Check the centralized lubrication system of the mixer mainframe to ensure that the saturation and status of the lubricant meet the operational requirements. Attention should be paid to the timely replacement of the gear oil of the reducer of the mixer mainframe in accordance with the relevant regulations, and strictly distinguish between the different types of gear oil used in winter and summer. Mixer main building in the water scale, powder scale, admixture scale, oblique belt motor and other parts are generally referred to collectively as four scales, in the structure structure, attention should be paid to maintain sufficient relative independent activity space between the scales. Pay attention to keep the sensor dry and clean, check whether the terminals are reliably and firmly connected, so as not to affect the accuracy of the scale.

 

　　In the maintenance of the inclined belt motor, the gear oil of the reducer needs to be replaced regularly. Like the host gear oil, it is also necessary to strictly distinguish the gear oil type applicable in winter and summer. According to the daily operation and working principle of concrete mixing plant, the mixing host can be the core working part of the whole equipment, which directly affects the overall operation efficiency and operation quality of mechanical equipment. The tank commonly used in the mixer is a very important working equipment, which may be worn out in daily operation. In addition, the liner plate, mixing shaft arm, mixer blade and other parts may also wear out, so the concrete mixing plant needs to be inspected and replaced in time. At the same time, pay attention to adjust the gap between the wall of the mixer host and the blades to ensure the actual operating requirements of the load. After each completed concrete mixing operation, the whole tank needs to be cleaned inside and outside, while checking whether concrete remains in the mixer spindle, blades, tank wall and other locations.

 

　　Specifically, sand and stone account for a large proportion of the raw material composition of concrete, which tends to generate a large amount of dust when mixing. The serious problem of dust pollution around concrete mixing plants not only affects the ecological environment, but also increases the probability of construction workers suffering from lung disease and other related diseases. In addition, the sewage generated during the cleaning process inside the concrete mixer is likely to have a negative impact on the water environment in the area where the project is located, and the water pollution problem is serious.
