[0002] The foundation pit is a deep pit or a large pit dug below the ground in civil engineering and construction engineering for building basements, subway stations, underground passages, underground pipelines, foundations, etc. The foundation pit guardrail is a safety protection facility specially used for surrounding the construction site foundation pit or deep excavation area, aiming to prevent personnel from accidentally falling, prevent construction materials or equipment from falling into the foundation pit, and remind the surrounding personnel of the existence of potential dangerous areas. The foundation pit guardrail is an important part of the safety measures of the construction site, and is crucial for the safety of the construction personnel and the passing pedestrians.

[0003] The design of the existing foundation pit guardrail has obvious defects, mainly including its non-dismountability, insufficient adaptability to special-shaped foundation pits, and significantly insufficient warning ability in the night or low light conditions. Due to the fixed design of these guardrails, it is difficult to flexibly respond to the changing needs of the construction site, especially when encountering non-standard size or special-shaped foundation pits, the insufficient adaptability leads to security protection vulnerabilities. In addition, its night warning function is insufficient, often unable to effectively remind the construction personnel and the passing pedestrians of the potential risks due to the non-obvious warning signs, increasing the possibility of accidents. These shortcomings limit the safety and effectiveness of the foundation pit guardrail in actual application, and need to be improved through design and technological innovation.

[0006] According to one aspect of the utility model, the T-shaped connecting rod comprises: a limiting body, a rod body and a conical head;

[0007] The limiting body is fixedly connected above the rod body, and the conical head is fixedly connected below the rod body, and the diameter of the rod body is smaller than the size of the left and right connecting components.

[0008] According to one aspect of the utility model, the cavity base includes: cavity base upper surface rectangular connecting port and circular sand inlet, the rectangular connecting port with the column corresponding connection.

[0009] According to one aspect of the utility model, the infrared automatic response lighting assembly includes: horizontal plate, LED lamp, microprocessor infrared sensor and light response module

This design not only improves the construction efficiency, but also reduces the construction cost, and at the same time makes the guardrail can be reused in different construction occasions, prolongs the service life of the product.

[0013] The design of left and right connecting components can make the assembled guardrail rotate at a certain angle, so that the whole guardrail structure is suitable for foundation pits of various shapes. The design of cavity base increases the stability of the guardrail. By filling sand into the sand inlet of the base cavity and the plug-in structure of the column and the base, the stability and wind resistance of the guardrail can be effectively improved, and stability can be maintained in severe weather conditions.

The tip of the conical head can reduce the resistance during plugging, making the installation process smoother. This design is particularly suitable for occasions that require frequent installation and disassembly, improving work efficiency. After the conical head is inserted into the connecting component, due to its shape characteristics, it can form a tighter contact with the inner wall of the connecting component, enhancing the stability of the connection. This physical locking effect can effectively prevent the T-shaped connecting rod from loosening during use, and at the same time achieve secondary fixation of the guardrail, thereby ensuring the overall stability and safety of the guardrail.

The infrared automatic sensing lighting assembly combines infrared sensors and light sensing modules, which can automatically turn on and off according to changes in environmental light and human activity, effectively saving energy and reducing unnecessary waste of electrical energy, in line with the concept of green environmental protection. The outer side of the infrared automatic sensing lighting assembly is fixedly connected with the slogan board, which can be used to publish safety warning information or indication information, enhancing the information transmission function of the guardrail, and helping to improve the management efficiency and safety level of the construction area.
