Description

Technical Field

[0001] The utility model relates to the technical field of traffic engineering, in particular to a construction fence. Background Art

[0002] Traffic engineering is the basic theory of research and development of traffic engineering discipline. It is a relatively young discipline derived from road engineering. It integrates several aspects related to traffic, such as people, vehicles, roads, environment and energy, into the unity of road traffic for research, in order to seek the planning, construction and management scheme of the traffic system with the maximum road capacity, the least traffic accidents, the fastest operating speed, the lowest transportation cost, the smallest environmental impact and the lowest energy consumption, so as to achieve the goals of safety, speed, economy, convenience, comfort, energy saving and low pollution.

[0003] In the construction of traffic engineering, corresponding fences are usually used for protection. There is a construction fence with a Chinese patent publication number of CN203188683U. The construction fence can be installed by inserting the vertical pole into the base and then inserting the iron pin into the through hole on the vertical pole. During the construction process, if the fence needs to be enclosed in a circle or a quadrangle or other required shapes, the hook of the first construction fence can be buckled with the hanging ring of the second construction fence, and the hook in the second construction fence can be buckled with the hanging ring in the third construction fence, and so on. At the same time, the angle of each fence base is adjusted to achieve the best stress angle, thereby ensuring the stability and tightness of the entire construction fence. When dismantling the construction fence, you only need to pull out each hook from the hanging ring and pull out the iron pin in the vertical pole; during the loading process, the fence and the base are loaded separately, which can greatly save loading space.

[0004] However, since the structure is an integral structure after being assembled, it is not convenient for entering and exiting the inside and outside, and its practicality is insufficient. Utility Model Content
