[0034] like Figure 1-4 As shown, the present invention provides an anti-sinking manhole cover and an installation method thereof.

[0035] like Figure 1-3 As shown, an anti-sinking manhole cover includes a manhole cover plate 5, at least two limiting sheets 3 are arranged vertically above the manhole cover plate 5, a shielding sheet is arranged on the limiting sheet 3 located at the top, stone layers 1 are arranged between the limiting sheets 3 and between the limiting sheets 3 and the manhole cover plate 5, respectively, the limiting sheet 3 is composed of an embedded plate 3-1 and a movable plate 3-3 that are movably connected, and the longitudinal projection area of ​​the movable plate 3-3 is larger than the longitudinal projection area of ​​the manhole cover plate 5.

[0036] In the present invention, in order to prevent the manhole cover from collapsing in the asphalt pavement, multiple stone layers 1 are arranged above the manhole cover plate 5 to fill the gap above, which not only supports the surrounding asphalt, but also fills the road surface above the manhole cover plate 5, so that the road surface above the manhole cover plate 5 is smooth with the asphalt pavement. Among them, the multi-layer limiting sheet 3 is to improve the stability of each layer of stone above the manhole cover plate 5, so that each layer of stone is evenly stressed.

[0037] Among them, the longitudinal projection area of ​​the movable plate 3-3 is larger than the longitudinal projection area of ​​the manhole cover 5. In this way, when repairing, the stone layer 1 can be removed, the movable plate 3-3 can be opened, and the manhole cover 5 can be taken out, allowing workers to go down the well for repair.

[0038] At the same time, the setting of the stone layer 1 can effectively allow the accumulated water on the road surface to penetrate to the bottom. A water-absorbing layer can be set under each stone layer 1 to carry out preliminary water absorption, and the water can also be diverted to the water guide groove on the road surface. If the cost is not considered, water-absorbing stone can be used as the main raw material of the stone layer 1.

[0039] like Figure 4 As shown, the above-mentioned anti-sinking manhole cover, the installation method thereof comprises the following steps:

[0040] Step 1: excavate a manhole cover installation area, the manhole cover installation area is located at the upper end of the wellhead, the shape of the manhole cover installation area is cylindrical, the diameter of the manhole cover installation area is larger than the diameter of the wellhead, and the depth of the manhole cover installation area is within half a meter;

[0041] Step 2: Install the manhole cover plate 5 at the bottom of the manhole cover installation area so that the manhole cover plate 5 covers the wellhead;

[0042] Step 3: placing a stone layer 1 on the manhole cover 5, and installing a limiting sheet 3 on the stone layer 1, so that the edge of the limiting sheet 3 is located in the asphalt pavement outside the manhole cover installation area;

[0043] Step 4: placing a stone layer 1 on the limiting sheet 3, and installing the limiting sheet 3 on the stone layer 1, so that the edge of the limiting sheet 3 is located in the asphalt pavement outside the manhole cover installation area;

[0044] Step 5: Repeat step 4 until the height difference between the uppermost limiting sheet 3 and the asphalt road surface is 1-3 cm;

[0045] Step 6: Lay an anti-skid layer on the uppermost limiting sheet 3 so that the anti-skid layer is flush with the level of the asphalt pavement.

[0046] In the above steps, the manhole cover installation area in step 1 is used to install an anti-sinking manhole cover described in the present invention, which includes a manhole cover plate 5 and a limiting sheet 3 above it and a stone layer 1. Finally, the manhole cover installation area is filled so that the filled manhole cover installation area is smooth with the asphalt pavement. Due to the full filling inside, the support function for the asphalt pavement can be completed, thereby preventing the manhole cover from collapsing on the asphalt pavement. In steps 3 to 5, the function of the limiting sheet 3 is to layer the stones into multiple stone layers 1, so that when encountering disasters such as earthquakes, or when used normally, the gravity of the stones can be shared, thereby achieving the function of protecting the pavement. Therefore, the number of limiting sheets 3 is more than one, and there are multiple limiting sheets in the longitudinal direction. Generally, there can be three layers of limiting sheets 3, and the height difference between the uppermost limiting sheet 3 and the asphalt pavement is 1-3 cm. In this way, an anti-skid layer is laid on it in step 6 to make it flush with the level of the asphalt pavement. The pavement can be used normally.

[0047] In the present invention, in order to stably fix the edges of the upper and lower multiple limiting sheets 3 in the asphalt pavement, the edges of the two upper and lower adjacent limiting sheets 3 are connected by a fixing rod 4. The fixing rod 4 can be a rod that passes through the limiting sheets 3 in sequence, or it can be multiple rods that are sequentially connected to the edges of the two adjacent upper and lower limiting sheets 3 for fixing. In the present invention, it is recommended to use the first type, that is, a rod that passes through the limiting sheets 3 in sequence, and the edges of each limiting sheet 3 are respectively provided with holes. The construction personnel only need to insert the fixing rod 4 into the asphalt pavement in a scorched state according to the size, and pass through the holes between each limiting sheet 3 to achieve the position fixation of the multi-layer limiting sheets 3.

[0048] In the present invention, in order to facilitate the installation of the limiting sheet 3, the inner panel 3-1 of the limiting sheet 3 includes a first sub-inner panel and a second sub-inner panel, and the first sub-inner panel and the second sub-inner panel have opposite edges with notches, and the notches of the first sub-inner panel and the second sub-inner panel are arranged opposite to each other, and the opposite edges of the first sub-inner panel and the second sub-inner panel are detachably connected;

[0049] The movable plate 3-3 of the limiting sheet 3 includes a first movable sub-plate and a second movable sub-plate, and the opposite edges of the first movable sub-plate and the second movable sub-plate are detachably connected via a locking mechanism 3-2;

[0050] The notch edge of the first sub-inner panel is movably connected to the first sub-movable panel, and the notch edge of the second sub-inner panel is movably connected to the second sub-movable panel.

[0051] In this way, during installation, the limiting sheet 3 can be heated by hot melting, so that the first sub-embedded plate and the second sub-embedded plate are respectively embedded in the asphalt pavement under high temperature, so that during installation, the asphalt pavement can be quickly installed without damaging it. When it is necessary to go down the well later, just open the movable plate 3-3, take out the manhole cover 5, and go down the well to complete the maintenance process.

[0052] For more convenient operation, considering that the present invention has a stone layer 1, the first sub-movable plate has a hollow structure inside, and the upper and lower inner walls of the first sub-movable plate are respectively provided with a slide groove 3-5, and at least one heat conducting block 3-4 is slidably connected to the slide groove 3-5, and the heat conducting block 3-4 is connected to the first sub-movable plate;

[0053] The interior of the second movable sub-plate is a hollow structure, and the upper and lower inner walls of the second movable sub-plate are respectively provided with two slide grooves 3-5, and at least one heat conducting block 3-4 is slidably connected to the slide groove 3-5, and the heat conducting block 3-4 is connected to the second movable sub-plate.

[0054] The present invention realizes that when going down the well, the movable plate 3-3 can be completely embedded in the inner plate 3-1 through the sliding connection between the movable plate 3-3 and the inner plate 3-1, so that it has a larger movable area. At the same time, through the embedding method, when the limiting sheet 3 is heated, the inner plate 3-1 can be heated by heating the movable plate 3-3 through the heat conductive block 3-4. In the present invention, the material of the limiting sheet 3 can be selected from materials with high thermal conductivity, such as iron sheets and steel plates, which have both high hardness and high thermal conductivity. In the present invention, the limiting sheet 3 is installed by high heat, and the inner plate 3-1 can be inserted into the asphalt pavement in a high heat state.

[0055] In the present invention, a plurality of holes 3-6 are provided on the movable plate 3-3, which can increase the air permeability of the manhole cover installation area and also have a good water guiding effect when guiding water, thereby preventing the limiting sheet 3 from being corroded by the accumulated rainwater.

[0056] At the same time, in order to better limit the various limiting sheets 3 in the manhole cover installation area, the present invention sets a limiting ring 6 on the manhole cover plate 5, and the limiting ring 6 is used to pass through the fixing rope 2, and the fixing rope 2 is also used to pass through each of the limiting sheets 3 and then fix it on the top layer. During installation, the fixing rope 2 can be passed through the limiting ring 6 on the manhole cover plate 5, and then the construction worker pulls the fixing rope 2 upward to keep it in a vertical state, and fills stones at the same time, fixes a layer of limiting sheets 3, and then passes the fixing rope 2 through the limiting sheets 3 and then winds the fixing rope 2 on the current limiting sheets 3, so that the construction worker pulls the fixing rope 2 upward to keep it in a vertical state, and fills stones at the same time, fixes a layer of limiting sheets 3, and then passes the fixing rope 2 through the limiting sheets 3 and then winds the fixing rope 2 on the current limiting sheets 3, and repeats the process until the limiting sheets 3 on the top layer are already located in the position about inside the road surface 1-3. The method of the present invention can make the position of each limiting sheet 3 relatively fixed under the action of the stone layer 1, ensuring the stability of the limiting sheet 3.

[0057] In the present invention, a water-absorbing layer is arranged on the top of the manhole cover 5, which is used to absorb some rainwater or corrosive seepage water. An anti-skid layer is arranged on the topmost limiting sheet 3, which is used to ensure the stability of pedestrians walking on the road.

[0058] In the present invention, the bottom of the manhole cover 5 is used to support the limit block 7 of the well side wall, which is used to prevent the manhole cover 5 from moving at the wellhead. At the same time, a water absorption layer is arranged on the top of the manhole cover 5, and a water absorption layer is arranged on the outside of each stone layer 1, and the water absorption layer is used to absorb some rainwater or corrosive seepage water.

[0059] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
