AI Technical Summary

Technical Problem

Existing safety protection devices cannot effectively protect the inner wall of deep foundation pits during construction. As the depth increases, the impact resistance weakens, and the construction time is extended, resulting in poor protection.

Method used

The structure employs a protective plate and protective netting. A buffer structure and airbags are installed on the side of the protective plate facing away from the pit. The protective netting is used to offset the force of soil sliding and enhance impact resistance. The airbags are replenished with air through air intake pipes to increase buffering performance and reduce noise transmission.

Benefits of technology

It improves the impact resistance and buffering performance during deep foundation pit construction, reduces airbag leakage caused by prolonged construction time, and enhances the protective effect and sound insulation performance.

Abstract

The application discloses a deep foundation pit construction safety protection device, which comprises a protection plate and a protection cloth net, the protection plate is divided into a buried end and an aboveground end, one side of the protection plate facing the foundation pit is in a planar shape, the other side of the protection plate is provided with a buffer structure, the inside of the protection plate is provided with a connecting mechanism, the other end of the connecting mechanism is provided with a supporting plate, the bottom of the supporting plate is provided with the protection cloth net, and the protection cloth net is located in the inside of the foundation pit; when the device is used, the inside of the foundation pit is protected by the protection cloth net, the soil sliding in the foundation pit can generate pressure on the protection cloth net, so that the protection plate has a counterclockwise rotation trend around the barycenter, and when an external object impacts the protection plate, the protection plate has a clockwise rotation trend, so that the soil sliding in the foundation pit can offset the force received by the protection plate when the protection plate is impacted.
