Use Of Steel Fiber For Hydro Tunnel Projects

Production of hydropower using the river water that is fed by the melting snow is one of the most preferred ways of power generation. This is so because such projects subsidiary benefits such as irrigation benefits and if constructed with good material, they become economical in terms of the cost of maintenance and operation. Steel fiber reinforced concrete finds one of the most prominent applications in the projects related to hydro projects. This is the frequently encountered stress-resultant combination of high compressive forces and low bending moments in such projects can predominantly match by using the material properties of steel fibers only. This assures a low maintenance cost because of the material's resistance against the concentrated loads. Also, the use of this material simplifies the construction process and accelerates the speed of project execution. There has been a rising use of steel fibers in hydro projects purely on a volume fraction basis. As a result, consequently, a larger network of fibers are used within the concrete matrix which further alters the performance of the concrete due to higher confinements.

 

Hydro projects require great strength to make them reliable and durable. This is because any mistake done here can lead to irreversible damage. Moreover, the cost f repair is also high. The aspect ration i.e. the length and the diameter of the steel fiber for hydro tunnel projects has a great bearing on the performance of the steel-fiber-reinforced concrete (SFRC). Higher aspect ratios tend to yield better performance due to the anchorage lengths and fiber network. Precision Drawell has experience of over 20 years to manufacture steel fibers. Apart from different sizes and aspect ratios, they have the capability of manufacturing steel fibers in a different shape; straight, hooked end, and undulated, different form, different tensile strength i.e., high, medium, and low, and different materials, i.e. mild steel, galvanized or stainless steel. The company uses the best of the experience and technology to choose the right shape, form, size, tensile strength, and the material of steel fiber to be used in the project. Besides this, the completely new wire drawing machine can also be incorporated to add service mix.

According to the experts from the International Tunnel Association (ITA), use of steel fibers in place of traditional reinforcement can save the cots of tunnel lining by up to 40 percent. In addition to this, these steel fibre for hydro projects tunnel has numerous other qualities such as reduced use of time and steel for construction. This also means reducing the emissions of carbon dioxide. This is very important for the construction of eco-friendly projects. Precision Drawell makes the use of best methods and up-to-date manufacturing strategies to make the finest material possible. It is well known for the hi-tech types of equipment and technically strong solutions that are provided through its well-established manufacturing facility. Among the many; wet wire drawing machine, OTO type dry drawing machine, pickling phosphating facility, a straight line drawing machines, spheroidize annealing furnaces, and bell annealing furnaces are some of the machines that cater the needs of hi-tech manufacturing.
