[0002] Temporary fences are usually needed in various types of engineering construction. Temporary fences are used to demarcate construction areas to prevent non-construction personnel from entering the designated dangerous work areas, so as to achieve the purpose of safe construction. Existing temporary fences are usually made of steel frames and color steel plates, which are relatively fixed facilities. After multiple independent temporary fence units are transported to the site, they are spliced ​​in sequence along the designated dangerous work areas to form a complete temporary fence facility. The above-mentioned temporary fences have the following problems: First, the fixed fence units take up a lot of space, which is not convenient for storage and allocation, nor is it convenient for transfer and transportation to the site and between different construction sites; secondly, when arranging on site, multiple people need to be used to splice them piece by piece, and the gaps formed between adjacent fence units need to be sealed by other means, which requires a lot of work and low construction efficiency; thirdly, the enclosed dangerous work area is usually a circular closed area, and the existing temporary fences are not easy to construct the aforementioned closed circular area.

[0003] In summary, it is necessary to develop and design a movable temporary enclosure for dangerous work areas to solve the aforementioned technical problems. Utility Model Content
