U steel arch as a support tool has a great impact on the safety of coal mine tunnels and other scenes. Therefore, the quality of this product is the top priority in the production process, and it must also be guaranteed the stability during its use. After all, "safety and stability" is the foundation of all projects. However, many U steel arches on the market occasionally can not avoid the situation of instability, so what are the reasons for this phenomenon?

A lot of engineering practice shows that in high-stress soft rock roadways, high-resistance shrinkable U steel arch supports are unstable and destroyed. In addition to strength reasons, they are more structurally unstable. There are many reasons for this situation. In summary, there are three main reasons:

1. The strength of the U steel arch connector is low, or the structure of the connector is unreasonable, causing the U steel arch structure to become unstable;

2. Poor interaction between surrounding rock supports, resulting in poor stability of U steel arch support structure;

3. The U steel arch support does not adapt to the deformation characteristics of the surrounding rock of the roadway, resulting in structural instability of the U-shaped steel support.

The above are the reason for the U steel arch instability summarized by ZXSteelGroup for you. Since its establishment in the 1990s, ZXSteelGroup has been constantly improving its technology and optimizing its manufacturing procedures, and has done its utmost to provide our customers with the most stable and reliable U steel arch on the market.
