High-strength prestressed steel strands: How should bridges be constructed
High-strength prestressed steel strands are widely used in the industry. So how are they used? First, we install a prestressed steel pipe. Then, use this material for installation and confirm the accurate position of the corrugated pipe during use, with the top surface of the box or the support platform serving as the cutting point for the wire. Then 4 cut by the wheel teeth, root by root, and use certain products to fix it to ensure the overall construction.
Each raw material entering the site needs to be matched using this vernier caliper for subsequent inspection. Confirm the position according to the design drawings, then fix it and start the installation. After the concrete pouring and maintenance, test it with standards. Once a certain strength is reached, install the jack on top and start the tensile construction. Finally, after completion, we need to seal the cross-beam at low speed. This completes the overall corresponding force performance.
Let's take a look at the honeycomb structure, which is made of a thin circle and winding. This structure is also widely used. Therefore, the high-strength prestressed steel strands used in bridges are very necessary for the post-tensioned concrete structure. The flat corrugated pipe is made based on this circular pipe and is usually used with different work templates. Here, we suggest that you should use steel strips for winding, bite the mouth tightly during the material process, and press the raised corrugations.
The high-strength prestressed steel strands produced by our company have good versatility, interchangeability, reasonable formula, easy to use, and are very light. After completion, you should conduct an earthquake resistance test, 30 If there is no leakage or seepage for minutes, and the tension is intact and the tensile time can be completed, it indicates that the work is completed. Generally, all pipes can be sealed, and drainage pipes can also be installed, which can meet the needs of pressure grouting and vacuum installation.
