The invention relates to the technical field of municipal construction equipment, in particular to a warning board for municipal engineering construction. A technical problem to be solved is that theeffect of an existing warning board is poor at nights. In order to solve the technical problem, the invention provides the warning board for municipal engineering construction; the warning board for municipal engineering construction comprises a box body; a movable plate is fixedly connected to the bottom of the internal wall of the box body through a telescopic device; a one-way air flow device is arranged on one side of the telescopic device; an electronic display device is arranged at the top of the movable plate; a solar power supply device is arranged at the top of the movable plate; thetelescopic device comprises a gas tank welded at the bottom of the internal wall of the box body; and four cylinders are welded at the top of the gas tank. According to the warning board for municipalengineering construction, people can see clearly when the light is poor; and people can pay attention to the warning board in the distance so that people can get ready in advance to prevent vehicle accidents due to having no enough time to respond; and therefore, the life safety of a vehicle owner is enhanced.
Description
technical field [0001] The invention relates to the technical field of municipal construction equipment, in particular to a warning sign for municipal engineering construction.
