THE MANUFACTURE PROCESS OF CENTRAL CONCRETE PILE IN THE FACTORY INCLUDES THE FOLLOWING STEPS:
-Step 1: Prepare production materials (sand, stone, cement, reinforcement, ...);
-Step 2: Welding the steel cage including erection of prestressed steel, steel belt, pile head code;
-Step 3: Steel stretch: As a pre-stressed step for concrete piles according to the designed stresses to have bending resistance moments when in use. Steel pulling results are kept in the laboratory;
-Step 4: Centrifugal rotation: This is a very important step to compact the concrete and normally there are 4 levels of rotation so that the pile can achieve the design quality;
-Step 5: Steamer pile: This step takes the pile into the steaming boiler at a temperature of about 100oC - / + 20 to decide to remove the mold early, hot steam will accelerate the process of concrete hydration in temperature environment. high. Usually steamed pile about 8 hours. Or depending on the technology of each manufacturing plant;
-Step 6: Remove the mold and check the product: This may be the last step if not through a high-pressure furnace depending on the progress or decisions related to the goods stored at the factory. In this step we will check and classify the types of piles of the right quality or other considerations;
-Step 7: Steaming through a high-pressure furnace: This is the way at factories with orders that need to be supplied quickly or want to increase the concrete grade, and as soon as the pile is removed from the high-pressure furnace, we can Pile the finished product;
-Step 8: Steam through the high pressure furnace: This is the period to check the quantity, quality, types of goods and transport to the project.
