A manhole ring beam 2 is installed above the brick-lined shaft 1. The thickness of the brick-lined shaft 1 is the same as that of the manhole ring beam 2. The inner wall of the brick-lined shaft 1 and the part between the brick-lined shaft 1 and the original ground layer are plastered with cement to prevent the brick-lined shaft 1 from being eroded by liquid. A manhole ring 3 is provided above the manhole ring beam 2, and a manhole cover 4 is installed above the manhole ring 3. The manhole ring 3 includes a manhole cover seat 16 and a manhole seat 13. The manhole seat 13 includes a vertical part 18 and a horizontal part 17. The vertical part 18 is cylindrical. The manhole cover seat 16 is annular and is connected to the inner wall of the vertical part 18. The manhole seat 13 is connected to the manhole ring beam 2 by expansion bolts 5. The gap 7 between the manhole ring beam 2 and the original concrete road layer 6 is filled with a concrete mixture, and the gap 7 and the top surface of the original concrete road layer 6 are leveled with a ruler and a scraper. The manhole ring 3 and the original concrete road layer 6 are leveled through a leveling layer 8, and the leveling layer 8 is poured with the same material as the original concrete road layer 6. A gasket 9 is provided between the horizontal part 17 and the manhole ring beam 2, so that the manhole cover 4 is flush with the surrounding road surface after installation, ensuring the smoothness of the road surface. Below the original concrete road layer 6 is the original ground layer structure. The top opening of the brick-lined shaft 1 can be higher than, lower than or equal to the bottom surface of the original concrete road layer 6. The top of the manhole ring beam 2 is lower than the top surface of the original concrete road layer, ensuring that after the manhole ring 3, the manhole cover 4 and the manhole seat 13 are installed on the manhole ring beam 2, the position of the manhole cover 4 is not higher than the top surface of the original concrete road layer 6.

[0025] During the process of cutting and excavating the road surface, the periphery of the manhole ring beam 2 is cut and excavated into a regular hexagon structure form as Figure 3 shown for construction. Refer to Figure 1 to install the manhole ring beam 2, the manhole ring 3 and the manhole cover 4, so that the installation construction of the manhole ring beam 2, the manhole ring 3 and the manhole cover 4 is in force balance, ensuring the structural stability.
