| description | The invention provides a prefabricated concrete inspection well. The prefabricated concrete inspection well comprises a base, a lower wellbore, a wellbore adjusting section, a well circle seat and a well cover plate which are sequentially arranged from bottom to top, wherein a well cavity communicating with the lower wellbore and the wellbore adjusting section is formed in the lower wellbore and the wellbore adjusting section; and an upper opening communicating with the well cavity is formed in the well circle seat, an anti-collapse piece is further arranged on the upper side of the well circle seat, embedded pipes are arranged in the inner wall of the lower wellbore and the inner wall of the wellbore adjusting section in an embedded mode, and a pulley assembly is arranged in the upper opening of the well circle seat. According to the prefabricated concrete inspection well, the problems that a roadbed around the well cover plate of the inspection well is extremely prone to sink and collapse, and heavy objects |
