Description

Technical Field

[0001] The present application relates to the technical field of foundation pit protection, and more specifically, to a foundation pit protection device. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. It is mainly used for pouring and constructing the foundation of the building. After the foundation pit is excavated, protective devices need to be installed on the adjacent ground to achieve the purpose of warning and protecting pedestrians and prevent them from falling and getting injured.

[0003] Prior art publication CN214883717U discloses a foundation pit protection device. The device comprises at least two protection bodies; a connecting structure connected between two adjacent protection bodies to allow relative rotation; and a support base movably mounted on the bottom of the at least two protection bodies, with a nail plate disposed on the bottom of the support base. This device allows for an adjustable angle between two adjacent protection bodies, thereby providing a barrier for various types of foundation pits.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] 1. The length of the device body cannot be adjusted. After splicing, it cannot adapt to the length of the foundation pit edge. There will be a situation where one more piece is longer and one less piece is shorter.

[0006] 2. The device is simply connected to the ground at the top of the foundation pit through the support bottom plate, and the supporting strength of the device is poor. When pedestrians accidentally collide with the device, the device is likely to fall into the foundation pit, and the protective performance is low.

[0007] Regarding the above-mentioned related technologies, the inventor believes that the length of the device body cannot be adjusted, and after splicing, it cannot be adapted to the length of the foundation pit edge. If there is one more piece, it will be longer, and if there is one less piece, it will be shorter. The device is simply connected to the ground at the top of the foundation pit through a supporting bottom plate, and the supporting strength of the device is poor. When a pedestrian accidentally collides with the device, the device is likely to tip over into the foundation pit, and the protective performance is low.

[0008] In view of this, we propose a foundation pit protection device. Utility Model Content

[0009] 1. Technical problems to be solved

[0010] The purpose of the present application is to provide a foundation pit protection device, which solves the problem in the above-mentioned background technology that the length of the device body cannot be adjusted and cannot be adapted to the length of the foundation pit edge after splicing. If one piece is too much, it will be longer, and if one piece is too little, it will be shorter. The device is simply connected to the top ground of the foundation pit through a supporting bottom plate, and the supporting strength of the device is poor. When a pedestrian accidentally collides with the device, the device is likely to tip over into the foundation pit, resulting in low protective performance. The technical effect is achieved.
