 &The characteristics of our company's new square culvert mold are: First, the parts of the mold can cooperate and coordinate with each other. The mold is very stable, which not only greatly improves the accuracy of the product, but also greatly increases the pass rate; second, By replacing modules or changing the number of modules, the shape and size of the mold can be changed to manufacture square tube culverts of the required size. For square tube culverts of the same shape, only one set of molds need to be customized, which greatly reduces production costs. It also saves the time spent on making molds and speeds up the production schedule. Fourthly, it has a simple structure, easy operation and good practicability.
The square culvert components adopt a shed-type pressureless steam curing method. According to the principle of concrete strength increase, the time and amplitude of steam curing heating and cooling are controlled. The concrete is water-pressurized and allowed to rest for an hour before being pressureless steam cured. The heating gradient does not exceed &dg per hour, and the maximum temperature is &dg. The cooling gradient does not exceed &dg per hour. During the entire steam curing process, a dedicated person is responsible for checking and keeping records. The steam curing is controlled by a microcomputer control system based on the time data adjustment.
After the strength of the concrete reaches the strength that can be hoisted, first remove the end formwork, then remove the outer formwork, and tighten the inner formwork at the same time. After the bottom formwork is lifted by the jack, the top of the component is separated from the inner formwork, and the square culvert component is made. The culvert component and the bottom mold are moved out of the mold simultaneously, and the difference between the surface temperature of the square culvert component and the ambient temperature during demoulding is not greater than &dg.
Component Repair and Maintenance After the square culvert components are hoisted to the storage site, the square culvert components will be marked (production date, product model, etc.), and local defects in the square culvert components will be repaired. After repair, the square culvert components will be cured with water. Maintenance methods can be carried out by spraying or soaking in water. Component repair and maintenance: The finished components will be inspected for structural dimensions, appearance inspection and other relevant specifications and standards. At the same time, the components will be inspected, repaired and maintained again, and qualified products will be marked and await shipment from the factory.
The internal dimensions of the square culvert component of the embodiment are width, height, length, and wall thickness. To this end, the square culvert components can be combined to form an underground comprehensive pipe corridor according to the required length of the pipeline. The end molds of the prefabricated square culvert are connected according to the convex and concave patterns on both sides of the square culvert components. The square culvert components are also connected with water-swellable rubber strips to ensure tightness. The main raw materials of prefabricated square culverts are cement, fly ash, sand, gravel, admixtures, steel bars, embedded iron parts, etc. The concrete is waterproof concrete, and the mix ratio is cement g, fly ash g, sand g, gravel g, water g, admixture g, and steel bars g. Mix in an appropriate amount of micro-expanding agent to ensure that the anti-permeability level reaches the highest level and the anti-freeze level.
Therefore, our company ensures that high-quality, stable, and even development routes meet the needs of the enterprise for the industry market, focusing on development and integration with international technology. Through unremitting advancement of technology, the enterprise's application, innovation, development and progress will be more perfect.
