What is a trench cover?
Answer: ditch cover plate is a kind of appliance with one partition for mesh. Here it refers to the fence where the garbage is blocked by the sewer mouth. Trench cover plate has excellent corrosion resistance, high strength, strong pressure resistance, impact resistance and bearing capacity, easy to install, adjustable trench cover plate. Because there is no secondary use value, it has the characteristics of natural anti-theft.
How to control the quality of the trench cover plate is a very serious problem. Let's have a brief understanding of how to do it.
A: 1. Control the raw materials
The incoming inspection of the steel materials used in the trench cover plate is the primary link, which determines the final forming and performance of the trench cover plate. Our company has strict quality inspection standards. Only by selecting high-quality raw materials can we ensure the performance and quality of the field frequency, and strictly enforce the entry system of raw materials. All the sand, stone and steel bars used must be qualified. Mix concrete in strict accordance with the mix proportion approved by the test engineer. According to the theoretical mix proportion, determine the operation mix proportion of each plate of materials, make corresponding measuring tools, weigh accurately, and its deviation meets the specification requirements. At the same time, tag out the construction, mark the concrete operation mix proportion, so as to facilitate inspection and supervision.
2、 Strictly control production and design links
According to the production standard of trench cover plate, no error is allowed. Continuously introduce domestic advanced production equipment and technology, improve the quality of existing trench cover products, and strive to develop new products. According to the market demand, the detailed product R & D process is formulated to ensure the completion of new product R & D in a relatively short time.
3. Do a good job in the delivery inspection of the finished products. After the completion of our finished products, there will be professional quality inspectors to conduct quality inspection and test whether the products are standard. If the products are unqualified, they must be re produced.
It should be noted that the test engineer shall, in accordance with the requirements of the specification, spot check a group of test pieces for each machine and each shift, build a concrete test piece curing pool on the site, and maintain the test pieces here before they are sent to the laboratory. The laboratory shall conduct compressive strength test, and resolutely destroy the unqualified trench cover plate.
