A protective device for foundation pits of highway bridge construction

Abstract

The invention discloses a foundation pit protection device for highway bridge construction, and relates to the field of foundation pit protection. The foundation pit protection device comprises a protection main plate. Multiple back face supporting frames are arranged on one side of the protection main plate. Multiple fixing rivets are arranged at the bottom ends of the multiple back face supporting frames. A buffer through hole is formed in the back face of each buffer rubber layer. Multiple bottom plates are arranged on the portions, located at the bottom ends of the buffer rubber layers, onone side of the protection main plate. Rotation supporting columns are arranged at the top end of the protection main plate. A first rotating shaft is arranged at the top end of each rotation supporting column. The top end of each second rotating shaft is connected with a solar panel. According to the foundation pit protection device, by means of the buffer rubber layers, buffer springs and the buffer through holes, impact caused when a person collides the protection device is converted into potential energy of the buffer springs, a display can generate enough brightness at night to remind pedestrians to pay attention to a foundation pit, the impact can be converted into pressure of the back face supporting frames on the ground, and the problem that because no good fixing devices are arranged, the protection device is likely to deviate is effectively solved.

Description

technical field [0001] The invention relates to the field of foundation pit protection, in particular to a foundation pit protection device for highway bridge construction. Background technique [0002] Nowadays, various cities are developing rapidly. During the construction of highways and bridges, it is often necessary to construct foundations. Usually, several large foundation pits will be dug on the ground. In order to prevent people from entering by mistake, guardrails are usually set up. That is, the foundation pit protection device. [0003] Nowadays, all foundation pit protection devices in the market generally do not have anti-collision facilities. When some pedestrians accidentally collide with the protection device by bicycle, it will cause pedestrian injury or cause certain economic losses, and the warning sign of the protection device is generally composed of a reflector. Not only The reminder function at night is not obvious enough, and it cannot provide a goo...
