The invention discloses an inspection well cover with a fixed structure, and relates to the field of municipal administration. The inspection well cover structurally comprises a wellbore and a well cover body; the well cover body is installed on a connecting ring, and multiple threaded rods are equidistantly arranged between the connecting ring and the wellbore in the circumferential direction; the lower ends of the threaded rods are fixed to the wellbore, and the upper ends of the threaded rods penetrate through the connecting ring and are slidably connected with the connecting ring; and adjusting nuts matched with the threaded rods in a threaded mode are arranged on the rod bodies, located on the lower part of the connecting ring, of the threaded rods in a sleeving mode. According to theinspection well cover with the fixed structure, by arranging the threaded rods and the adjusting nuts, the altitude difference of the well cover body can be accurately controlled, and well cover excursion is prevented; and meanwhile, through the arrangement of the threaded rods, the connection position of the well cover body and the wellbore can be strengthened, and the possibility of well coverand surrounding road surface sinking and fractures is greatly reduced.
