Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to a high pier steel bar binding protection frame for bridges. Background Art

[0002] Subway construction refers to the construction process of subway tracks, stations and other infrastructure underground. This includes underground tunnel excavation, track laying, station construction, ventilation system installation and other work. The elevated bridge structure that will exist on the subway construction line is used to support the subway track across roads, rivers, railways and other terrains. The bridge pier is a columnar structure that supports the bridge deck in the bridge. It is usually made of concrete or steel. It plays an important role in supporting and carrying the subway in subway construction. During the construction of the bridge pier, steel bars will be tied to strengthen the quality of the pier. When tying, it needs to be protected by a protective frame. The protective frame is a support structure used to provide safety protection. It is usually used in high-altitude operations, construction, bridge construction and other fields. It can effectively prevent falls and other risks and can be adjusted and assembled according to actual construction needs.

The key technical point is that the anti-fall net can prevent the operator from falling out of the operating frame. When the operator is performing steel bar tying work, the operator wears a safety belt. Wearing the safety belt can effectively prevent the operator from slipping or stepping on air and falling when performing high-altitude operations on the mold turning operation platform. The safety protection effect is good, which is conducive to ensuring the personal safety of the operator.
