[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, at least one rib is provided in the concave cavity of the cover body in an area where no planting box is arranged.

[0007] Furthermore, the tie rod hole vertically penetrates the rib plate.

[0008] Furthermore, the concave cavity of the cover body is divided into a plurality of independent areas by ribs, and a planting box is arranged in each independent area.

[0009] Furthermore, all the ribs in the cavity pass through the center of the cavity, and the angles between two adjacent ribs are the same.

[0010] Further, the contour shape of each independent area is the same as the contour of the planting box.

[0011] Furthermore, the pull rod comprises: a screw rod, a nut end of the screw rod is outside the cover body, and a threaded end of the screw rod passes through the pull rod hole and enters the well frame and is threadedly connected with the nut.

[0012] The beneficial effects of the utility model are:

[0013] 1) Arrange planting soil and green plants in the planting box to facilitate movement, so as to facilitate the opening of the manhole cover and the restoration of green plants;

[0014] 2) The planting effect is good, the whole structure can be integrated with the environment, forming an invisible form and easy to open;

[0015] 3) The ribs can effectively enhance the overall rigidity and bearing capacity of the cover;

[0016] 4) When the cover is not opened, the screw rod can fall down and be supported by the cover or the rib plate to hide the pull rod, prevent the pull rod from affecting passage, and avoid safety accidents caused by the pull rod being exposed. BRIEF DESCRIPTION OF THE DRAWINGS
