[0023] Reference Figure 1-4 This utility model discloses a protective device for a foundation pit, comprising a foundation pit body 1. Protective structures are provided at both the front and rear ends of the foundation pit body 1, and both protective structures are identical. Each protective structure includes an outer frame 2 and an inner frame 3. The inner ends of the outer frame 2 are fixedly connected to the outer sides of the inner frame 3 via corner blocks 4. Both the outer frame 2 and the inner frame 3 are I-shaped. A support frame 5 is fixed to the top of the outer frame 2. Reinforcing holes 6 penetrate the inner top surfaces of both support frames 5, extending into the inner side of the outer frame 2. All reinforcing holes 6 have the same inner diameter. In the prior art, this type of device does not provide protection for the foundation pit. The pit protection structure is designed with multiple reinforcements, which makes it prone to instability due to external factors, directly affecting its effectiveness. To address this issue, protective structures can be installed at both the front and rear ends of the main pit 1. This involves using outer frame 2, inner frame 3, and corner blocks 4 between the outer and inner frames 2 and 3 to double-reinforce the support frame 5. Reinforcement holes 6 are also provided to reinforce the inner side of the support frame 5, enhancing its rigidity and stability. This better protects the surrounding environment and construction safety, reducing safety hazards caused by the instability of individual support columns.

By inserting positioning columns into the inner side of the insertion positioning holes 14, the two outer frames 2 are reinforced, thereby achieving the effect of protecting the front and rear sides of the foundation pit. A reinforcing rod 15 is fixed between the two telescopic lower rods 7 on adjacent horizontal sides. The reinforcing rod 15 is cylindrical and is used to reinforce the two telescopic lower rods 7, thereby enhancing the stability of the display board 12.

[0027] A dustproof plate 16 is fixed to the top of the display frame 11 to prevent dust from entering the top of the display frame 11. The bottom surfaces of the two outer frames 2 and the inner frame 3 are roughened to avoid instability. Multiple corner blocks 4 are set at right angles to improve the external reinforcement effect of the corner blocks 4.

[0028] Working principle: First, protective structures are set at both the front and rear ends of the main body 1 of the foundation pit. That is, the outer frame 2, the inner frame 3, and the corner block 4 between the outer frame 2 and the inner frame 3 are used to double reinforce the support frame 5. Reinforcement holes 6 are opened to reinforce the inner side of the support frame 5, thereby enhancing the rigidity and stability of the support frame 5, thus better protecting the environment around the foundation pit and construction safety, and reducing safety hazards caused by the instability of individual support columns. Then, positioning columns are inserted into the inner side of the insertion positioning holes 14 to achieve the effect of reinforcing both outer frames 2, thereby achieving protection on both the front and rear sides of the foundation pit. Then, by setting two telescopic upper rods 8 and telescopic lower rods 7, the height position of the two telescopic lower rods 7 can be changed according to actual needs, thereby changing the overall height of the display board 12.
