Its fast and convenient installation method can greatly shorten the construction period and reduce traffic pressure, and is therefore widely used in municipal engineering.

[0022] In the specific implementation process, it is worth pointing out that the shaped steel formwork 3 can shield the poured concrete layer 6, thereby ensuring that the concrete layer 6 can be smoothly formed, and the reinforcing ribs 7 can improve the pouring strength of the concrete layer 6;

[0023] Furthermore, a base 4 fixedly connected to the inner wall of the concrete layer 6 is attached to the top of the shaped steel formwork 3, and a manhole cover 5 is placed on the top of the base 4;

[0024] In the specific implementation process, it is worth pointing out that the base 4 can support the manhole cover 5, thereby closing and shielding the prefabricated modular post-injection inspection manhole;
