    Finely-rolled threaded steel bars are widely used in large-scale water conservancy projects

     

    Bridge construction technology took a giant leap forward with the introduction of the post-tension rod system, a pioneering move. This innovative construction method uses high-strength steel to strengthen bridge structures and is expected to improve the durability, efficiency and safety of infrastructure developments.

    In recent years, soil nailing has seen an increase in popularity due to advancements in technology. With the use of geotechnical engineering software, engineers can model and simulate the effects of soil nailing in different climates and terrains. This allows for more accurate predictions of the performance of reinforced structures and minimizes the risk of failure during the construction process.

    Soil nailing has also been utilized in the transportation industry. In the construction of highways and railways, soil nailing has been used to stabilize slopes and prevent landslides. By reinforcing the soil, soil nailing can make transportation routes safer and more reliable.

    Fully threaded steel bars are currently used to anchor and support the dam body form of the dam foundation. In the cable-stayed bridge, fully threaded bars are used as the main ribs and bridge foundations of the main tower. The use of fully threaded steel bars saves steel, reduces component area and reduces component weight.

    The continuous external thread is hot rolled. The shape of thread bar is shown as following figure. The main dimension ranges from ⌀15mm-⌀50mm and the grade ranges from 500/630Mpa to 1200/1330Mpa.
