How to control the quality of the trench cover is a very serious problem. Let's briefly understand how to do it.
1. Turn off the raw materials
The inspection of the steel materials used in the trench cover is an important link. It determines the final formation and performance of the trench cover. Our company has strict quality inspection standards. Only high-quality raw materials can guarantee the performance and quality of the field frequency. The entry system of raw materials must be qualified for the sand, stone and steel bars used. Mix the concrete in strict accordance with the mix ratio approved by the test engineer. According to the theoretical mix ratio, determine the operation mix ratio of each plate, and make the corresponding measuring tools, and the weighing is accurate, and the deviation meets the specification requirements. At the same time, the concrete operation mix ratio is indicated for inspection and supervision.
2. Strictly control production and design links
According to the production standard of trench cover, there must be no errors. Continuously introduce advanced production equipment and production technology in-house, improve the quality of existing trench cover products, and strive to develop new products. And according to market needs, a detailed product research and development process has been formulated to ensure that the research and development of new products can be completed in a relatively short time.
3. Do the factory inspection of finished products,
After our finished products are completed, there will be quality inspectors to conduct quality inspections to check whether the products are standard. If the products are unqualified, they must be re-produced.
It should be noted that, in accordance with the requirements of the specification, the test engineer randomly inspects the test specimens of each machine and each shift, and builds a concrete specimen curing pool on the construction site. The specimens are cured here before the test specimens are sent to the laboratory. Compressive strength test, resolutely destroy the unqualified trench cover.
