[0020] In this example: a manhole cover with an adjustment ring includes a manhole barrel 1, a manhole seat 2 is provided on the manhole barrel 1, and a manhole cover 3 is provided on the manhole seat 2. The manhole seat 2 and the manhole barrel 1 are connected by an adjustment ring 4, a hook 5 is provided on the adjustment ring 4, and an anti-fall net 6 is provided on the hook 5.

[0021] Specifically, the well barrel 1 is the main structure of the device, which is used for water pouring and guiding, and the well seat 1 is installed in a pre-buried manner.

[0022] Specifically, the well seat 2 is used to support the well cover 3. When installing the well seat 2 and the well cover 3, it is necessary to ensure that the well seat 2 and the well cover 3 are flush with the asphalt road surface.

[0023] Specifically, the adjusting ring 4 is made of concrete material, and the adjusting ring 4 is used to bear and buffer the pressure from various road conditions on the well seat 2 and the well cover 3, so the concrete material has good compressive resistance; wherein, the adjusting ring 4 adopts an annular structure, and its diameter is greater than or equal to the inner diameter of the well barrel 1, preferably, equal to the inner diameter of the well barrel 1.

[0024] Specifically, during installation, the well barrel 1 is pre-buried and installed, then the well seat 2 is installed on the adjusting ring 4, and then the well cover 3 is installed on the well seat 2; wherein, the distance between the adjusting ring 4 and the road surface is controlled at 12-15cm, preferably, the distance between the adjusting ring 4 and the road surface is designed to be 12cm.

[0025] Specifically, the hook 5 is embedded in the adjusting ring 4 when it is cast and formed. The hook 5 is used to hang the anti-fall net 6. The hook 5 is made of anti-corrosion and rust-proof material, preferably 304 stainless steel. Among them, there are several hooks 5, and multiple hooks 5 can make the anti-fall net 6 stable and balanced. Preferably, 8 hooks 6 are provided and evenly distributed on the inner wall of the adjusting ring 4. Several hooks 6 are arranged on the same horizontal plane to ensure the balance of the anti-fall net.

[0026] Specifically, the hook 3 is divided into a bolt portion and a semicircular hook portion, the bolt portion is embedded in the adjusting ring 4, and the semicircular hook portion is arranged on the outer side of the adjusting ring 4.

[0027] In this example, the well seat 2 includes a horizontal plate 7 and a vertical plate 8 integrally connected at a right angle, a folded edge seat 14 is formed at the right-angle connection end of the horizontal plate 7 and the vertical plate 8, and the horizontal plate 7 is recessed upward to provide an upper recessed hole 9.

[0028] Specifically, in order to stably place the manhole cover 3, a right angle is provided, the right angle is formed by connecting the horizontal plate 7 and the vertical plate 8, and a folding seat 14 is formed;

[0029] Specifically, the folding seat 14 is formed by vertically sinking downward along the inner wall of the well seat 2, and the thickness of the well cover 3 is consistent with the folding height of the folding seat 14. This design enables the well seat 2 and the well cover to be flush after the well cover 3 is placed on the well seat 2.

[0030] In this example, the top of the adjusting ring 4 is recessed downward to form a lower recessed hole 10, and the side end of the adjusting ring 4 is provided with a screw hole 16.

[0031] In this example, a column 11 is provided between the upper concave hole 9 and the lower concave hole 10, and an upper reinforcing rib 12 and a lower reinforcing rib 13 are provided at the upper and lower ends of the column 11, respectively.

[0032] Specifically, in the traditional manhole seat 2, the pressure of the manhole cover 3 is borne only by the horizontal plate 7 and the vertical plate 8. The horizontal plate 7 will transfer the force to the asphalt pavement, and the landfill contact end of the asphalt pavement and the horizontal plate 7 is prone to pavement fracture. At the bottom of some complex road conditions, the asphalt pavement at the contact end may even fracture and tilt, which will cause the overall manhole seat 2 to bulge or sink relative to the road surface, affecting driving safety and drainage.

[0033] Specifically, in order to solve the above problems, a column 11 is provided, which directly connects the horizontal plate 7 of the lecture 2 with the adjusting ring 4, that is, a part of the pressure on the horizontal plate 7 is directly transmitted to the adjusting ring 4 through the column, and then a part is transmitted to the asphalt pavement, thereby alleviating the bearing pressure of the asphalt pavement.

[0034] Specifically, the upper reinforcing rib 12 and the lower reinforcing rib 13 are arranged opposite to each other, the upper reinforcing rib 12 can increase the pressure resistance of the receiving end of the cross plate 7, and the lower reinforcing rib 13 can increase the pressure resistance of the receiving end of the adjusting ring 4, so that the column 11 is not easy to tilt or bend.

[0035] Specifically, the upper concave hole 9 and the lower concave hole 10 are used to receive the two ends of the clamping column 11 so that the column 11 will not shift.

[0036] Specifically, there are several upper recessed holes 9 and lower recessed holes 10, which are evenly arranged on the bottom of the well seat 2, and evenly arranged on the top of the adjustment ring 4. Preferably, four upper recessed holes 9 and four lower recessed holes 10 are used, which are symmetrically arranged on the well seat 2 and the adjustment ring 4 in the southeast, northwest and northeast directions, respectively, wherein the positions of the upper recessed holes 9 and the lower recessed holes 10 correspond to each other, and the corresponding columns 11 are correspondingly connected; in the above, the four recessed holes correspond to the four columns 11, which can protect the well seat 2 and the well cover 3 in a balanced and all-round manner.

[0037] Specifically, the upper concave hollow hole and the lower concave hole 10 can also adopt an annular groove design, that is, an annular groove is provided below the well seat 2 along the circumference of the well seat 2, and an annular groove is provided above the adjustment ring 4 along the circumference of the adjustment ring 4, and the upper annular groove and the lower annular groove are connected by a ring.

[0038] In this example, an elastic cushion layer 18 is provided at the contact end between the top of the column 11 and the upper recessed hole 9 and at the contact end between the bottom of the column 11 and the lower recessed hole 10 .

[0039] Specifically, in order to prevent the contact end of the column 11 and the concave hole from loosening or making abnormal noise when a vehicle passes by, an elastic cushion layer 18 is provided. The elastic cushion layer 18 is made of an elastic material with corrosion-resistant and wear-resistant properties, such as vulcanized chloroprene rubber;

[0040] Specifically, the chloroprene content in the vulcanized chloroprene rubber is greater than 40%. After vulcanization treatment, the rubber pad has good wear resistance, corrosion resistance, grease resistance and weather resistance; the pad layer can resist falling off and aging failure within 10 years.

[0041] In this example, a buffer hole 15 is provided on the folding seat 14 , and a buffer rubber pad is provided on the buffer hole 15 .

[0042] Specifically, the buffer rubber pad is also made of a corrosion-resistant and wear-resistant elastic material, preferably vulcanized chloroprene rubber.

[0043] In this example, the vertical plate 8 is fixedly connected to the screw hole 16 by means of expansion screws 17 .

[0044] Specifically, in order to further stabilize the well seat 2, the expansion screws 17 and the screw holes 16 are used to fix the vertical plate 8 on the adjustment ring 4, that is, the horizontal plate 7 is connected to the adjustment ring 4 through the columns, and the vertical plate 8 is connected to the adjustment ring 4 through the expansion screws. Therefore, the horizontal plate 7 and the vertical plate 8 are both stably designed, so that the well seat 2 can stably support the well cover 3, making it less likely for the well cover to tilt or sink.

[0045] In this example, the well base 2, the well cover 3 and the column 11 are all made of ductile iron, and the anti-fall net 6 is made of moisture-resistant and corrosion-resistant material.

[0046] Specifically, ductile iron is a common material in the prior art and will not be described in detail again.

[0047] The beneficial effects of the utility model are as follows: by providing a column and an adjusting ring, the horizontal plate of the well seat is indirectly connected to the adjusting ring, thereby alleviating the bearing pressure of the filler near the well seat; by adopting concrete material for the adjusting ring, the pressure-bearing performance is good; by adopting expansion screws for the fixed connection between the vertical plate and the adjusting ring, the vertical plate has a certain bearing force and can bear the pressure of the well cover; therefore, through the above design, the overall bearing pressure of the well seat is strong and it is not easy to tilt or sink, that is, the well cover will not tilt or sink.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
