How to control the quality of the Trench Cover
How to control the quality of the trench cover is a very serious problem. Let's take a brief look at what to do if it is done.
1.put the good raw materials off
The inspection of the steel raw materials used in the trench cover is the first step. It determines the final forming and performance of the trench cover. Our company has strict quality inspection standards. The quality and raw materials can be selected to ensure the performance and quality of the field frequency. The entry system of raw materials must be fully qualified for the sand, stone and steel used. Mix the concrete strictly according to the proportion approved by the test engineer. According to the theoretical mix ratio, determine the operation ratio of each material, and make the corresponding measuring tools, the weighing is accurate, the deviation meets the requirements of the specification, and the construction is listed at the same time, indicating the concrete operation ratio, which is convenient for inspection and supervision.
2.Strictly control production and design
According to the production standards of the trench cover, there must be no errors. Continuously introduce domestic advanced production equipment and production technology, improve the quality of existing trench cover products, and strive to develop new products. And according to the needs of the market, we have developed a detailed product development process to ensure the completion of new product development in the shortest possible time.
3.Do a good job of factory inspection of finished products. After the finished products are finished, there will be professional quality inspectors to carry out quality inspections to check whether the products are standardized. If the products are not qualified, they must be re-produced.
It should be noted that the test engineer shall inspect a set of test pieces for each shift of each machine according to the requirements of the specification, and construct a concrete test piece maintenance pool at the site, where the test pieces are to be maintained before being sent to the test room, and the test room is made. The compressive strength test was carried out resolutely on the unqualified trench cover.
