Description

Technical Field

[0001] The utility model relates to the technical field of construction enclosures, and in particular comprises an assembled enclosure with a prefabricated concrete base. Background Art

[0002] With the continuous advancement of urbanization in my country, construction projects are spread all over the country. Before the construction of construction projects, the foundation trench or foundation pit is often excavated first. Therefore, before the construction of the foundation pit, a construction fence must be built to close the construction site and isolate the construction area from the living area and the pedestrian area outside the site to prevent unsafe factors at the construction site from causing harm to external pedestrians and vehicles, thereby avoiding safety hazards. Traditional construction fences have low installation efficiency, are not easy to dismantle, and have low turnover rates of materials after dismantling, resulting in material waste. In addition, the connection integrity between adjacent concrete enclosure base segments is poor, and the heavy weight makes construction and transportation difficult. When the wind blows, the overall stability of the enclosure structure is poor due to the bottom counterweight and fixation. It is easy to be blown down and cause safety hazards. Therefore, it is of great significance to study the prefabricated concrete base assembled enclosure. Utility Model Content
