[0013] 1. The highway construction warning device is provided with a removable connecting plate, and multiple unit shells can be connected in series by connecting the connecting bolts at the end of the connecting plate with the fixing block. The number of unit shells can be increased or decreased by disassembling the connection between the connecting bolts and the fixing block, thereby achieving the effect of convenient assembly and disassembly, and being more convenient to use.

[0014] 2. The unit shell of the highway construction warning device is a hollow structure, which is light and easy to carry. Water is injected into the base to increase the weight of the base, making it more stable when the unit shell is placed on the road alone. Since multiple unit shells are connected in series to form a ring structure, adjacent unit shells can be connected by bolts as the axis and rotated to different angles, which not only greatly improves the stability of the overall placement, but also can be adjusted to different enclosure shapes according to needs, so as to enclose and warn the construction area, which is more practical.
