Description

Technical Field

[0001] The utility model relates to the field of manhole cover maintenance, in particular to a maintenance and installation structure for an anti-sinking manhole cover. Background Art

[0002] Manhole covers are generally round and are used in green belts, sidewalks, motor vehicle lanes, docks, etc. They are used to cover roads or deep wells to prevent people or objects from falling. Manhole covers can be divided into single-layer, double-layer, cast iron, ductile iron, composite, cement, etc. Especially in urban roads, manhole covers are used more frequently because of municipal rain protection and drainage pipelines. When manhole covers are used for a long time, they will sink due to the rolling of vehicles or heavy objects.

[0003] There are anti-sinking manhole covers on the market, such as the anti-sinking manhole cover disclosed in CN206128131U, in which an annular sinking platform is set on the inner circle of the manhole seat, and the manhole cover is placed on the annular sinking platform. Although such a setting can prevent sinking, a gap will appear between the manhole cover and the annular sinking platform, causing the manhole cover to easily jump and generate noise.

[0004] At present, a rubber ring is set at the bottom of the manhole cover to prevent the manhole cover from jumping. However, the rubber ring is prone to aging and failure when repeatedly squeezed, has a short service life, and needs to be replaced more frequently. When switching, the appropriate rubber ring needs to be cut according to the size of the gap, which is difficult to cut and has high maintenance costs. Utility Model Content

[0006] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0007] A maintenance and installation structure for an anti-sinking manhole cover comprises a manhole seat and a manhole cover, wherein the inner ring of the manhole seat is provided with an annular sinking platform, the upper surface of the annular sinking platform is provided with an annular accommodating groove, the accommodating groove is filled with a buffering filler layer, and a steel wire rope is embedded on the surface of the buffering filler layer; the manhole cover is closed on the manhole seat, and the bottom is pressed against the steel wire rope.

[0008] Furthermore, the surface of some positions of the steel wire rope is also covered with a fixing layer, and the fixing layer is fixedly bonded to the buffer filler layer.

[0009] Furthermore, the buffer filler layer and the fixing layer are made of the same material.

[0010] Furthermore, the buffer filler layer is an adhesive layer with buffering properties.

[0011] Furthermore, the surface of the buffer filler layer is lower than the notch of the accommodating groove, and the steel wire rope is also arranged in the accommodating groove to achieve positioning.

[0012] Furthermore, the manhole cover is connected to the manhole seat by a hinge or a groove and tenon.

[0013] Furthermore, the steel wire rope is obtained by twisting a plurality of steel wires, and the outer circumference of a plurality of positions of the steel wire rope is also coated with an epoxy resin layer.

[0014] Furthermore, a buckle is assembled in the accommodating groove, and the steel wire rope is buckled and fixed by the buckle.

[0015] Furthermore, the buckle is fixed on the annular sink.

[0016] The technical solution provided by the utility model has the following beneficial effects:

[0017] In the present application, the steel wire rope is supported against the bottom of the manhole cover, and the buffer filler layer at the bottom of the steel wire rope plays the role of fixing the steel wire rope and providing buffering. When the manhole cover is subjected to pressure, the steel wire rope acts on the buffer filler layer, and the buffering of the buffer filler layer prevents the manhole cover from jumping, thereby achieving sound elimination. At the same time, the steel wire rope is not easily damaged by aging, which improves its durability and effectively saves maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0027] Embodiment 1

[0028] Reference Figures 1 to 3 As shown, the present embodiment provides a maintenance and installation structure for an anti-sinking manhole cover, including a manhole seat 10 and a manhole cover 20. Specifically, the manhole cover 20 is connected to the manhole seat 10 by a hinge or a groove. The inner circle of the manhole seat 10 is provided with an annular sinking platform 11, and the upper surface 111 of the annular sinking platform 11 is provided with an annular accommodating groove 12. The accommodating groove 12 is filled with a buffering filler layer 31, and the surface of the buffering filler layer 31 is embedded with a steel wire rope 40; the setting of the annular groove 12 can limit the buffering filler layer 31, and the steel wire rope 40 embedded in the surface of the buffering filler layer 31 also achieves good limiting fixation, making the structure more stable. The manhole cover 20 covers the manhole seat 10, and the bottom is pressed against the steel wire rope 40, that is, the bottom circle of the manhole cover 20 is abutted by the steel wire rope 40.

[0029] With such arrangement, when the manhole cover 20 is subjected to pressure, the steel wire rope 40 acts on the buffer filler layer 31, and the buffering of the buffer filler layer 31 prevents the manhole cover 20 from jumping, thereby achieving sound reduction. At the same time, the steel wire rope 40 is not easily aged and damaged, thereby improving durability and effectively saving maintenance costs.

[0030] Specifically, in this embodiment, the buffer filler layer 31 is an adhesive layer with buffering properties. The adhesive layer is fluid during preparation, which is convenient for filling and positioning the steel wire rope 40. After solidification, it has certain buffering properties, which is easy to prepare and easy to operate. The adhesive layer preferably uses an elastic grouting material disclosed in CN111792899A to prevent the road inspection well cover from bouncing, which has good performance. Of course, in other embodiments, materials such as casting glue, curtain wall glue or asphalt potting glue can also be used.

[0031] In this embodiment, in order to further fix the steel wire rope 40, the surface of some positions of the steel wire rope 40 is also covered with a fixing layer 32, such as the surface of the steel wire rope 40 at 0°, 90°, 180° and 270° positions is covered with a fixing layer 32, and the fixing layer 32 is fixedly bonded to the buffering filler layer 31, so that the steel wire rope 40 is completely fixed to prevent the steel wire rope 40 from being separated from the buffering filler layer 31. Of course, in other embodiments, the fixing layer 32 may not be provided.

[0032] Specifically, the buffer filler layer 31 and the fixing layer 32 are made of the same material, so there is no need to configure other materials, thus saving maintenance costs.

[0033] Specifically, in this embodiment, the surface of the buffer filler layer 31 is lower than the notch of the receiving groove 12, and the steel wire rope 40 is also arranged in the receiving groove 12 to achieve position limiting. In this way, the position limiting effect is better. Among them, the steel wire rope 40 protrudes from the notch of the receiving groove 12 to abut the manhole cover 20.

[0034] Through the scheme provided by this embodiment, the specific maintenance operation is as follows: when maintaining the manhole cover 20 in use, first, fence the road around the manhole cover 20, then open the manhole cover 20, and clean the annular sink 11; then configure the buffer filler layer 31, and fill the buffer filler layer 31 into the accommodating groove 12, roughly filling about half the depth of the accommodating groove 12, and then place the wire rope 40 in the accommodating groove 12. After the wire rope 40 is placed, cover the manhole cover 20, pre-press the wire rope 40, and make the wire rope 40 fit on the buffer filler layer 31; after the pre-pressing is completed, open the manhole cover 20 again, and cover a part of the surface of the wire rope 40 with a fixing layer 32; then, cover the manhole cover 20; and the repair is completed.

[0035] Embodiment 2

[0036] The maintenance and installation structure of the anti-sinking manhole cover provided in this embodiment is substantially the same as the structure of the first embodiment, except that: on the basis of the first embodiment, the following structure is added to the present embodiment: Figure 4 and Figure 5 As shown, the steel wire rope 40 is obtained by twisting a plurality of steel wires, and a plurality of positions of the steel wire rope 40 (such as Figure 4 The outer periphery of the steel wire rope 40 (six positions are shown) is also coated with an epoxy resin layer 41. In this way, the epoxy resin layer 41 can cover the outer periphery of the steel wire rope 40 and fill between the multiple steel wires, thereby further reinforcing the steel wire rope 40, better preventing the multiple steel wires constituting the steel wire rope 40 from spreading, and making the structure more stable.

[0037] Embodiment 3

[0038] The maintenance and installation structure of the anti-sinking manhole cover provided in this embodiment is substantially the same as the structure of the first embodiment, except that: Figure 6 As shown, in this embodiment, a buckle 50 is installed in the accommodating groove 12, and the steel wire rope 40 is buckled and fixed by the buckle 50. That is, the fixing layer 32 in the first embodiment is replaced with the buckle 50 in this embodiment; the steel wire rope 40 is buckled and fixed by the buckle 50, which can also well achieve anti-detachment.

[0039] Specifically, Figure 6 As shown, the buckle 50 is fixed on the annular sink 11. The buckle 50 can be pre-assembled on the annular sink 11, and then the buffer filler layer 31 is filled and the wire rope 40 is placed; when the wire rope 40 is placed, it is simultaneously inserted into the buckle 50, and the assembly is simple.

[0040] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
