Description

Technical Field

[0001] The utility model relates to the technical field of municipal road construction, in particular to a protective device used for construction. Background Art

[0002] Municipal administration refers to the various administrative management work of the city, and also refers to market trade affairs. Urban management work includes industry and commerce, transportation, public security, culture and education, environment, health, and infrastructure. The municipal subject acts on the municipal political subject and its process. In a broad sense, municipal administration refers to the various management activities and processes of the city's political party organizations and state power organs to achieve the political, economic, cultural and social development of the city itself and the country. In a narrow sense, municipal administration refers to the management activities and processes of the city's state administrative organs on various administrative affairs and social public affairs within the city's jurisdiction. Roads, in terms of meaning, are infrastructure for various trackless vehicles and pedestrians to pass through; according to their usage characteristics, they are divided into highways, urban roads, rural roads, factory and mine roads, forestry roads, test roads, competition roads, automobile test roads, workshop passages, and school roads, etc. In ancient China, there were also post roads. In addition, it also refers to the way to achieve a certain goal, the way things develop and change.

[0003] At present, when municipal road construction is carried out on the market, it is necessary to set up protective devices around the construction site. In actual use, when setting up protective devices around the construction site, most of them will install protective poles around the construction site. Considering the risk of the protective poles being accidentally touched and tipped over, pre-buried holes will be opened in the ground, and the position of the protective poles will be fixed by pre-buried bolts. When the diameter of the pre-buried hole is smaller than the circular hole on the protective pole, the subsequent pre-buried holes will not be able to fix the position of the protective pole, thereby affecting the subsequent installation of the protective pole.
