Code for design of concrete mixing station

This specification is applicable to concrete mixing station. The mixing station must have the functions of automatic metering and forced mixing, and the dust collector should be installed above the silo to meet the requirements of environmental protection. The mixing station requires reasonable organization, clear division of labor, and special types of work and testers to hold relevant certificates; Instruments and equipment meet the requirements of the project and have passed the inspection; Various rules and regulations are sound; The mixing area, storage yard and driving road should be hardened for foundation and pavement, and meet the requirements of heavy vehicle traffic and drainage. Equipment and facilities requirements: according to the concrete consumption of this project, the production capacity of the mixing station is reasonably set. In general, the cement tank: fly ash: mineral powder is configured according to the ratio of 1: 1, and the mixing station is reasonably set in consideration of factors such as long transportation distance and structural layout.

The measurement cycle shall comply with relevant regulations and have a valid certificate of conformity from the legal measurement department. The mixing and metering system shall be well maintained and run reliably. Quality control requirements in manufacturing process: establish raw material inspection account, raw material processing quantity registration form, raw material re-inspection sheet, and concrete mixing and concrete pouring record sheet issued by the tester before use, and measure strictly according to the quantity specified in the concrete pouring notice. Requirements for mixer operators: When lifting the hopper, it is forbidden to stand under the hopper, check the safety hook, check the brake condition of the mixer regularly, rinse and keep the mixer clean after work. Requirements for operators of special types of work: they must hold professional qualification certificates and operate in strict accordance with the operating rules of mechanical equipment to prevent illegal operation. Promotion material: Concrete mixing station is a kind of building material manufacturing equipment, which consists of five parts: mixer main machine, material weighing system, material conveying system, material storage system and control system. Its main working principle is that cement is used as cementing material, and raw materials such as sand and gravel, lime and cinder are mixed and stirred, and finally concrete is made as building wall material. Concrete mixing station has played an important role in China's construction industry since it was put into use, which is of course determined by its own advantages.
