Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a safety protection device for deep foundation pits in building construction. Background Art

[0002] A deep foundation pit in building construction refers to a foundation pit with a relatively large depth, usually used for projects such as underground parking lots, underground shopping malls, and subway stations. When constructing a deep foundation pit in building construction, special attention needs to be paid to aspects such as the support, drainage, monitoring, and safety of the foundation pit.

[0003] Generally, a fence is set at the upper end of the deep foundation pit to ensure that surrounding pedestrians or vehicles do not accidentally enter the dangerous area and provide additional safety protection.

[0004] However, since the bottom of the existing fence is connected to the ground by bolts, and the upper end of the fence is not further supported and fixed, the overall structure of the fence is very unstable, increasing the risk of tipping or collapsing, and the protection effect is poor. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a safety protection device for deep foundation pits in building construction to solve the above existing problems.
