[0035] refer to Figures 1 to 5 A method for covering a manhole cover under a road curb according to an embodiment of the present invention is described.

[0036] like Figures 1 to 5 As shown, the method for covering the manhole cover under the road curb according to an embodiment of the present invention includes:

[0037] Step 1: Design the length and width of the movable cover 100 according to the size of the manhole cover 20, and design the thickness of the movable cover 100 according to the distance from the manhole cover 20 to the road pavement 40;

[0038] Step 2: Pave the movable cover 100 on the manhole cover 20. The surface paving material and top elevation of the movable cover 100 are consistent with the surrounding road pavement 40.

[0039] Step 3: Design the width and height of the movable curb 200 according to the width and height of the fixed road curb 30, and design the length of the movable curb 200 according to the size of the manhole cover 20;

[0040] Step 4: Embed steel bars 220 in the fixed curbs 30 on both sides of the shielded area. The steel bars 220 extend toward the shielded area, and grooves are cut at corresponding positions on the lower ends of the movable curbs 200.

[0041] Step 5: Engage the lower end slot of the movable curb 200 with the embedded steel bars 220 extending from the fixed curb 30 , so that the movable curb 200 is embedded between the fixed curbs 30 on both sides of the shielding area.

[0042] like Figure 1 As shown, in order to alleviate traffic congestion, the road was widened. After the road was widened, the front end of the manhole cover 20 of the inspection well 10 was located in the motor vehicle lane 50, and the rear end of the manhole cover 20 was located in the green belt or the sidewalk, and the pavement surface 40 of the non-motor vehicle lane 50, resulting in the upper part of the manhole cover 20 on one side of the pavement surface 40 being left empty, posing a safety hazard.

[0043] like Figures 1 to 3 As shown, the length and width of the movable cover 100 are designed according to the size of the manhole cover 20, and the thickness of the movable cover 100 is designed according to the distance from the manhole cover 20 to the road pavement 40, so that the movable cover 100 can fill the empty area above the manhole cover 20. The paved movable cover 100 is placed within the opening range of the manhole cover 20 for shielding, and the surface paving material and top elevation of the movable cover 100 are consistent with the surrounding paving. Ensure that the lower manhole cover 20 is covered as a whole and does not exceed the range of the motor vehicle lane 50. A lifting hole 110 is opened on the movable cover 100. When the manhole cover 20 needs to be opened for inspection, the movable cover 100 is lifted by hooking the lifting hole 110 to move the movable cover 100 out of the shielding area.

[0044] The width and height of the movable curb 200 are designed based on the width and height of the fixed curb 30, and are consistent with those of the fixed curb 30. The length of the movable curb 200 is designed based on the dimensions of the manhole cover 20. Steel bars 220 are embedded in the fixed curbs 30 on both sides of the sheltered area, extending toward the sheltered area. Slots 210 are cut at corresponding locations on the lower ends of the movable curb 200. The slots at the lower ends of the movable curb 200 engage with the embedded steel bars 220 extending from the fixed curb 30, fitting the movable curb 200 between the fixed curbs 30 on both sides of the sheltered area. The material, width, and height of the movable curb 200 are consistent with those of the fixed curb 30, and its length is consistent with that of the movable cover 100, ensuring a harmonious and unified landscape effect. A through hole 230 is formed on the movable curbstone 200 . After removing the movable cover plate 100 , the movable curbstone 200 is lifted up by hooking the through hole 230 , and the movable curbstone 200 is moved.

[0045] Therefore, this method of covering the manhole cover under the road curb sets a movable cover 100 and a movable side stone 200 to cover the paved area left empty at the manhole mouth, which not only ensures the maintenance function of the manhole cover 20, but also prevents pedestrians from accidentally stepping on it and tripping; at the same time, the area of the movable cover 100 is filled according to the material of the paved area next to the road, taking into account the integrity and aesthetics of the road.

[0046] The movable cover 100 is provided in multiple pieces, and the multiple movable cover plates 100 are spliced together to cover the inspection well cover 20. The width of each movable cover plate 100 does not exceed 30cm, and the gap between the movable cover plate 100 and the road pavement 40 is 4mm; it is convenient to carry the movable cover plate 100 during maintenance.

[0047] like Figure 4 As shown, the movable cover 100 comprises a hot-dip galvanized angle steel frame 120, a reinforced concrete slab 130 with 220 steel bars, and a surface paving 140. The hot-dip galvanized angle steel frame 120 is protected by hot-dip galvanizing, and then concrete is poured to form the reinforced concrete slab 130 with 220 steel bars. The surface paving 140 is then paved atop the reinforced concrete slab 130 with 40 layers of surface paving. The design load-bearing capacity of the reinforced concrete slab 130 must meet the design load requirements of the area. The surface paving 140 is consistent with the surrounding paving and can be laid with materials such as artificial turf, sidewalk tiles, and colored asphalt.

[0048] like Figure 5 As shown, the diameter of the embedded steel bars 220 is 8mm, and the width of the slot 210 at the lower end of the movable curb 200 is 15mm. The length and position of the embedded steel bars 220 in the fixed curbs 30 on both sides of the shielded area should be consistent with the slot 210 of the movable curb 200 to ensure the fitting effect.

[0049] When the inspection well 10 needs to be opened for maintenance, first use the lifting hook to lift the movable cover 100 through the lifting hole 110 and move the movable cover 100 out of the shielding range; then use the lifting hook to lift and move the movable curb 200 through the through hole 230 of the movable curb 200, and then the inspection well cover 20 can be opened, and the maintenance personnel can go down the well for maintenance as usual. After the inspection is completed, the well cover 20 is closed, and the movable cover 100 and the movable curb 200 can be returned to their original state. When returning the movable curb 200, pay attention to the accurate fit of the slot 210 and the embedded steel bars 220 of the fixed curb 30 to avoid damaging the curb.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the spirit of the present invention.
