[0002] Municipal engineering refers to urban infrastructure projects that are planned, designed, constructed and maintained by the government or government departments, including roads, bridges, drainage systems, public transportation facilities, etc. The construction and maintenance of municipal engineering is crucial to the development of cities and the quality of life of residents.

[0003] Warning signs for municipal engineering are mainly used to remind citizens to pay attention to construction areas or traffic control areas to ensure construction and traffic safety. Warning signs usually indicate information such as the construction unit, construction time, construction content, and related safety tips to help citizens avoid accidents. Warning signs play an important warning and guiding role in municipal engineering and are one of the important measures to ensure construction and traffic safety.

[0004] The existing warning signs for municipal engineering still have the following problems: in actual use, the existing warning signs for municipal engineering are often used in construction sections, and road construction often generates a lot of dust, which is very easy to adhere to the warning signs. Over time, thick dust will adhere to the warning signs, which is very easy to affect the observation of personnel, thereby reducing the warning effect and bringing many inconveniences to the use;

[0005] Moreover, in municipal engineering, warning signs are mostly installed by screws, which makes it very inconvenient for personnel to replace warning signs of various contents and sizes. Moreover, when used at night, they are mostly warned by reflective layers, and the warning effect is not ideal.

[0006] In view of this, we propose a warning sign for municipal engineering. Utility Model Content
