　　Customized rail steel bending machine, precision hydraulic I-beam cold bending machine manufacturer

　　Bending machines are now widely available in the market, capable of completing bending tasks for various types of steel such as channel steel, track steel, and round steel pipes. Different types of steel arches and arches with different angles require different grinding tools. The recognition of the bending machine in the market is very high now. Greatly improving the construction speed of profiles and saving labor for workers.

　　The I-beam bending arch machine uses the high-pressure power of machinery to prevent leakage

　　(1) Construction process: Determine the leakage point → Clean the leakage base surface → Drill holes → Clean → Install grouting nozzles → Inject foam grout under high pressure → Observe → Repair leaks → Remove grouting nozzles → Repair slot holes → Inspect → Complete leak repair

　　(2) Construction requirements:

　　1. Inspection: Carefully inspect the leaking area, clean the dirt near the leaking area, and prepare for grouting.

　　2. Drilling holes: grout holes are drilled at the leaking area, and diagonal holes can be drilled through the crack surface, with a general hole spacing of 10cm-20cm.

　　3. Burial nozzle sealing: Bury the grouting nozzle and seal it with quick drying cement.

　　4. Grouting: Determine the grouting pressure and amount based on the specific situation of the leakage site. Use a leak sealing grouting pump to inject water-soluble polyurethane into the crack. When pure grout appears in all adjacent holes, move it to the adjacent holes and grout under the specified pressure until it cannot be injected (injection rate ≤ 0.01L/min), and then close the valve. (The general grouting pressure is 0.3Mpa).

　　5. After 72 hours, check if there is any water seepage at the leakage site. If there is no water seepage, remove the grouting nozzle, seal the base surface with fast drying cement, and smooth it out.

　　Among various types of steel

　　The groove type rail is particularly unique and is known as the "rail in the middle". Compared with ordinary steel rails, this type of rail has an asymmetric groove on the rail head, with a complex shape, making it the most difficult type of rail to roll. Currently, only a few countries in the world, such as Ukraine and Germany, have mastered the production technology of this type of steel rail.

　　For many years, we have adhered to the strategy of expanding our product market. Faced with the current situation of weakened domestic demand for heavy rail, Ansteel has continuously increased its technological research and development efforts, actively exploring products in emerging fields, and the research and development of groove rail is one of them. As early as 2003, groove rails were successfully developed and mass-produced, filling the gap in the development and production of groove rails in China. They were successfully applied to the customized rail steel bending arch machine and precision hydraulic I-beam cold bending machine manufacturer for the Dalian tram line renovation and expansion project.
