Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, and more specifically, it relates to a warning device for road construction. Background Technology

[0002] Roads, as essential transportation infrastructure, play a vital role in economic development, social operation, and people's daily lives. With the acceleration of urbanization, the continuous growth of traffic flow, and the aging and upgrading of infrastructure, road construction activities are becoming increasingly frequent. Whether it is the construction of new roads, road widening, road surface repair, or the laying of underground pipelines, projects require the closure or partial closure of roads for a certain period of time. Currently, to ensure the safety of pedestrians, vehicles, and construction workers during road construction, warning devices are generally set up to warn pedestrians and vehicles. The most commonly used warning device is the warning sign, which generally consists of a support frame and a warning slogan. When in use, the warning sign is placed outside the construction area to warn pedestrians and vehicles.

[0003] The existing application number is CN202323565623.7. This utility model relates to the field of road warning technology and discloses a road warning device for engineering road construction. It includes a fixed base plate, with mounting structures threaded to both sides of the top of the fixed base plate. A mounting frame is fixedly connected to the top of the fixed base plate near the mounting structures. A warning sign body is fixedly connected to the top of the mounting frame via a disassembly structure. The disassembly structure includes a fixing plate, which is fixedly connected to both ends of the top of the mounting frame. A push rod is threaded to one end of the fixing plate. This road warning device for engineering road construction allows for quick disassembly and replacement of the warning sign body through the disassembly structure. The fixing plate restricts the basic position of the warning sign body, and the push rod and push plate work together to clamp the warning sign body, facilitating quick disassembly and replacement according to different needs and increasing its applicability.

[0004] Based on the above, when existing warning signs are in use, since they are generally placed directly on the road, they are easily blown over by the wind or knocked over by non-motorized vehicles. If workers do not notice the sign falling over in time, it can easily affect the warning effect of the sign. Utility Model Content
