1. Basic concepts
Steel supports refer to steel pipes, H-shaped steels, angle steels, etc. used to enhance the stability of engineering structures. Generally, they are inclined connecting members, and the most common are herringbone and cross shapes. At present, steel supports are widely used in subways and foundation pits. Because the steel support can be recycled and reused, it is economical and environmentally friendly.
2. Scope of application
1. Simply put, the 16mm wall-thick support steel pipes, steel arches, and steel gratings used in the construction of subways are used for support. They block the soil wall of the culvert tunnel to prevent the collapse of the foundation pit. Widely used in construction.
2. The steel support components used in subway construction include fixed ends and flexible joint ends.
3. Specifications
The main specifications of steel support are Φ400, Φ580, Φ600, Φ609, Φ630, Φ800, etc.
