[0021] Hereinafter, embodiments of the highway construction level instrument of the present invention will be described with reference to the accompanying drawings. Example 1

[0022] Figure 1-3The utility model shows a highway construction level meter of an embodiment of the present invention, which includes a level meter 1: the surface of the level meter 1 is provided with an annular groove 2, the inner wall of the annular groove 2 is provided with a cover shell 3, and the bottom of the cover shell 3 is adhered with a gasket 4, which is a rubber ring. The setting of the gasket 4 is used to pad the bottom of the cover shell 3 to avoid the situation that the cover shell 3 directly contacts the inner wall of the annular groove 2 and causes the surface of the latter to be damaged. The surface of the level meter 1 and the bottom of the cover shell 3 are respectively fixedly connected with a cylindrical box 5 and a rectangular block 6.
