Description

Technical Field

[0001] The utility model relates to the technical field of sleeves, in particular to a novel shrinkage stamping pre-embedded sleeve. Background Art

[0002] A sleeve usually refers to a mechanical part that is used to fix and protect other parts. It can also reduce friction and withstand pressure. The sleeve is usually hollow and can be put on other parts to fix, position and protect them. In different engineering and mechanical equipment, the material, size and purpose of the sleeve will be different to meet different work requirements.

[0003] The embedded sleeve is a prefabricated embedded part for quick installation in shield tunnels. It is used in conjunction with external channels, mounting bolts and other related accessories. It is effectively consolidated with the interior of the tunnel concrete and transmits external force to the concrete inside the tunnel. It can be used to fix any mechanical components. It has good corrosion resistance and dynamic load capacity, and is easy to install, highly safe and has a long service life. It is used for fixed support, suspension, fixed communications, contact networks, water supply and drainage, fire protection, evacuation platforms, shield doors and other system supports, and is widely used in urban rail transit, railways and intercity fields.

[0004] The existing shrinkage stamping embedded sleeve has certain disadvantages when used. When the existing shrinkage stamping embedded sleeve is used, the embedded sleeve is usually an embedded part that is integrally stamped or cast from a stainless steel material, which has serious material waste and high process cost. Therefore, it cannot meet people's needs. Utility Model Content
