Since most private enterprises adopt family management and lack of professional production management personnel, there are many deficiencies in production management. Now I will give you a brief explanation of the concentration errors that concrete mixing plant are prone to make.
1. Mix the cement and admixture in the concrete mixing plant
(1) Each silo in the concrete enterprise should be listed and clearly marked, and the name, origin, model, inspection status, storage date, etc. of the raw materials should be indicated; (2) The closed storage tank in the company should be in the pump tube Lock the mouth to prevent unfamiliar drivers from making mistakes. The keys are kept by the company's full-time receivers and are responsible for unlocking and entering the warehouse; (3) Regularly train the full-time receivers to strengthen their work responsibility, improve business level, and eliminate Mixing silos of cement.
2. When the admixture of the concrete mixing plant is water, it cannot be removed.
(1) Strengthen the education of the operator's work responsibility, because the work is negligent, which leads to the existence of hidden engineering quality hazards, causing huge losses to the enterprise; (2) The mechanic strengthens the inspection of the equipment, do not wait for the equipment to be damaged before repairing, More maintenance and inspections should be done to eliminate problems in the bud. In addition, there are many types of electronic valves, don't be greedy for cheap, buy poor quality and have a short service life. Imported ones should be purchased. The quality is better, the accuracy and sensitivity are good, and the service life is long; (3) The tester should observe the production process Effectively monitor and control the quality of the concrete delivered from the factory to prevent unqualified products from being delivered to customers.
3. The mixing ratio of the concrete mixing plant is wrong.
(1) Strengthen the professional knowledge training of testers and operators, and be familiar with the materials stored in each silo and the name in the computer before taking the post; (2) After the operator enters the ratio in the computer, it must be reviewed and confirmed by the tester After signing the review sheet, the production can be organized.
4. Purchase and use unqualified materials
(1) The division of responsibilities of the company should be clear, the quality of the laboratory should be controlled, and the quantity of the receivers should be controlled; (2) The company should have a strict management system to prohibit employees from doing things that harm the public and the private; (3) The testers should be strengthened during the production process The inspection of the raw materials will promptly report any abnormalities and take emergency measures.
5. Concrete sent to the wrong construction site
(1) Strengthen the company's internal management, and strictly prohibit the delivery of concrete to the wrong construction site, resulting in hidden quality problems; (2) Production scheduling should strengthen the supervision and management of the vehicle operation by GPS. If the vehicle transportation direction is found to be wrong, verification should be stopped immediately.
The above is the concentration error that the concrete mixing plant is prone to make.
