Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a limiting manhole ring used for an anti-sinking manhole cover. Background Art

[0002] As the country continues to advance ecological and environmental governance, more and more cities have begun to address water pollution at the source. To this end, people dig sewers under urban roads and set up sewer wells and inspection wells on the roads. Manhole covers are usually needed to cover the sewer wells. Manhole covers are directly related to the flatness of the road surface, driving safety and comfort. At present, with the increasing traffic load and vehicle weight, manhole covers are prone to sinking together with the manhole seat during long-term use due to the simple support of the manhole cover and the manhole seat, resulting in a height difference between the manhole cover and the road surface, and causing uneven settlement of the road surface around the well, posing a safety hazard to pedestrians and vehicles.

[0003] For this reason, people have proposed anti-sinking manhole covers, which can reduce the sinking degree of manhole covers by improving the connection between the manhole cover and the manhole seat. In the process of installing anti-sinking manhole covers, it is often necessary to use a limit ring. The limit ring needs to be installed in the manhole seat, and then removed after compaction by small machinery. Then the anti-sinking manhole cover is installed and compacted together with the surrounding road surface. However, construction errors often occur in the construction of prefabricated or cast-in-place manhole seats. If the manhole seat is too large, it needs to be plugged later. If the manhole seat is too small, the limit ring cannot be installed.

[0004] Therefore, how to solve the problem of how to ensure that the limiting well ring can be used normally when there is a construction error in the well seat is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0034] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0035] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0036] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] In one embodiment, referring to the accompanying drawings, Figures 1 to 4 A limiting well ring for an anti-subsidence manhole cover, which reduces the diameter of a cylinder 100 so that one end of the cylinder 100 can be inserted into a well seat, and the cylinder 100 will not fall into the well, which can effectively solve the problem of construction errors in the well seat making it difficult to carry out construction, and ensure that the anti-subsidence manhole cover can be smoothly constructed within the allowable error range of the well seat, thereby ensuring the anti-subsidence effect of the anti-subsidence manhole cover, and has the characteristics of simple structure and easy operation.

[0039] Specifically, a limiting well ring for an anti-sinking well cover comprises a barrel 100 and a prefabricated adjustment ring 200, wherein the barrel 100 has a first end 110 and a second end 120, the first end 110 and the second end 120 are arranged opposite to each other, and the outer diameter of the barrel 100 decreases uniformly and linearly from the second end 120 to the first end 110. The inner wall of the prefabricated adjustment ring 200 matches the outer wall of the barrel 100, the inner diameter of the prefabricated adjustment ring 200 increases uniformly and linearly from one end to the other end of the prefabricated adjustment ring 200, and the inner diameter increase rate of the prefabricated adjustment ring 200 is the same as the outer diameter decrease rate of the barrel 100, so that the prefabricated adjustment ring 200 is sleeved on the outer side of the barrel 100. Accordingly, the first end 110 of the barrel 100 is suitable for matching with the well seat, so that the first end 110 of the barrel 100 is inserted into the well seat, and the prefabricated adjustment ring 200 is located on the well seat. The provision of the prefabricated adjustment ring 200 makes it convenient for construction personnel to inject concrete between the prefabricated adjustment ring 200 and the well seat according to the elevation data of the cylinder 100 to adjust the elevation difference between the road surface and the cylinder 100 .

[0040] In the prior art, when the inner diameter of the well seat is too large, it is often necessary to remove the well ring or to repair the leak between the limiting well ring and the well seat. When the inner diameter of the well seat is too small, the limiting well ring is difficult to insert into the well seat, and the well seat needs to be thinned. The operation process is complicated, resulting in extended construction time. In this embodiment, the outer diameter of the cylinder 100 increases uniformly and linearly from the first end 110 to the second end 120, so that the cross-section of the cylinder 100 is a variable cross-section. When a construction error occurs in the prefabricated well seat or the cast-in-place well seat, the inner diameter of the well seat is too large or too small, and the cylinder 100 can still be inserted into the well seat without the need for construction personnel to perform other processing, thereby effectively solving the problem of the well seat being unable to be constructed due to deviation. Moreover, the cylinder 100 does not need to be additionally provided with a fixed sliding device to prevent the limiting well ring from falling into the well.

[0041] In one embodiment, referring to the accompanying drawings, Figure 1 , Figure 2 , this embodiment further describes the cylinder 100. Specifically, a limiting well ring for an anti-sinking manhole cover further includes a plurality of elevation limiting blocks 130, and the plurality of elevation limiting blocks 130 are arranged in the cylinder 100 along the circumference of the cylinder 100.

[0042] Correspondingly, the elevation limit block 130 is located at the second end 120 of the cylinder 100 , and the upper end surface of the elevation limit block 130 is flush with the upper end surface of the cylinder 100 , so as to allow the level to measure the elevation data of the cylinder 100 .

[0043] Preferably, four elevation limit blocks 130 are provided, and the four elevation limit blocks 130 are evenly disposed on the inner wall of the cylinder 100 , and the angle between each two adjacent elevation limit blocks 130 is 90°.

[0044] In the prior art, no elevation stop block 130 is provided in the cylinder 100, and construction personnel often need to directly measure the elevation difference of multiple points on the upper end surface of the cylinder 100 through a level. However, the cylinder 100 is easily damaged during transportation or construction, which makes the upper end surface of the cylinder 100 uneven, thereby reducing the leveling accuracy. In this embodiment, an elevation stop block 130 is provided on the inner wall of the cylinder 100, and the elevation stop block 130 is not easy to be damaged. The elevation stop block 130 cooperates with the prefabricated adjustment ring 200 to assist the level to measure and obtain the inclination data of the cylinder 100. When in use, the first end 110 of the cylinder 100 is inserted into the well seat, and the construction personnel use a level to measure the elevation difference of the elevation limit block 130, and obtain the inclination data of the cylinder 100 through calculation. The construction personnel adjust the prefabricated adjustment ring 200 and the cylinder 100 according to the relevant information so that the inclination degree of the two is the same as the slope of the road, and inject concrete between the prefabricated adjustment ring 200 and the well seat to maintain the corresponding inclination angle of the prefabricated adjustment ring 200 and the cylinder 100.

[0045] Preferably, the elevation limit block 130 is provided with a through hole for a rope to pass through. When adjusting the height of the cylinder 100 , construction workers can use a rope to pass through several through holes of the elevation limit block 130 to adjust the inclination of the cylinder 100 .

[0046] Preferably, the prefabricated adjusting ring 200 is made of concrete, and the strength of the concrete used in the prefabricated adjusting ring 200 is higher than that of the concrete of the well seat. Of course, in actual production applications, the elevation limit block 130 can also be set to other numbers to achieve the purpose of leveling with the prefabricated adjusting ring 200. It is not described in detail here and is within the protection scope of the present utility model.

[0047] In one embodiment, referring to the accompanying drawings, Figure 2 , this embodiment further illustrates the cylinder 100. Specifically, a bottom cover 140 is further provided in the cylinder 100, and the bottom cover 140 is detachably provided in the cylinder 100 and is located at the first end 110. It can be understood that by detachably providing the bottom cover 140 in the cylinder 100, when the first end 110 is inserted into the wellbore, the bottom cover 140 is provided in the cylinder 100, and when concrete is poured around the limiting well ring, the bottom cover 140 can prevent substances in the external environment such as concrete from entering the well seat, and at the same time, the provision of the bottom cover 140 can improve the structural strength of the cylinder 100, and avoid deformation of the cylinder 100 when compacting the concrete,

[0048] Furthermore, an inner wall support is also provided on the inner wall of the cylinder 100, and the inner wall support is detachably connected to the cylinder 100. The inner wall support can further improve the structural strength of the cylinder 100 and prevent the cylinder 100 from deforming when the concrete is poured.

[0049] Specifically, the inner wall support is configured as a cross support frame 150 , and the cross support frame 150 includes two support rods 151 . The two support rods 151 are cross-connected and configured, and an end of each support rod 151 is configured to contact the inner wall of the cylinder 100 .

[0050] Preferably, two cross support frames 150 are provided, namely a first cross support frame and a second cross support frame, which are arranged in sequence from top to bottom in the cylinder 100. The second cross support frame is arranged at the first end 110 and is located above the bottom cover 140, and the first cross support frame is arranged in the middle of the cylinder 100.

[0051] In actual production applications, the number of the cross support frames 150 is not limited to two, and may also be set to other numbers to achieve the purpose of improving the structural strength of the cylinder 100.

[0052] In one embodiment, this embodiment provides another specific form of the inner wall support. Specifically, the inner wall support is configured as an annular structure that matches the well seat, and the inner support includes a telescopic rod, a first support half ring and a second support half ring. Correspondingly, both ends of the first support half ring are respectively provided with mounting holes, and both ends of the second support half ring are respectively provided with clamping rods that match the mounting holes. The clamping rods and the mounting holes are mutually clamped and matched to achieve the connection and fixation of the first support half ring and the second support half ring. Among them, the telescopic rod includes a first rod member and a second rod member, and one end of the second rod member is movably arranged in the first rod member and is threadedly connected to the first rod member to adjust the length of the telescopic rod. Correspondingly, both ends of the telescopic rod are respectively provided with arc-shaped support plates that match the first support half ring and the second support half ring. When in use, construction workers connect and fix the first support half ring and the second support half ring, place the first support half ring and the second support half ring in the cylinder 100, set the telescopic rod between the first support half ring and the second support half ring, and adjust the supporting force of the inner wall support by adjusting the length of the telescopic rod to improve the structural strength of the cylinder 100.

[0053] Of course, the inner support member can also be set as a pressure-resistant ring that matches the cylinder 100. In actual production applications, the inner support member can also be set in other forms, which are not explained here one by one and are all within the protection scope of the present utility model.

[0054] In one embodiment, referring to the accompanying drawings, Figure 1, this embodiment further describes the cylinder 100. A handle hole 160 is also provided on the cylinder 100, and the provision of the handle hole 160 facilitates the construction personnel to carry the cylinder 100 to the well seat. Correspondingly, a reinforcing plate 170 is also provided on the inner wall of the cylinder 100, and a through hole matching the handle hole 160 is provided on the reinforcing plate 170, and the reinforcing plate 170 is located at the handle hole 160, so as to improve the local strength of the cylinder 100.

[0055] Of course, in actual production applications, in addition to the handle hole 160, a handle can also be provided on the cylinder 100 to facilitate construction personnel to extract and place the limiting well ring. This is not described in detail here and is within the protection scope of the present utility model.

[0056] In one embodiment, this embodiment further illustrates the barrel 100, setting the outer diameter of the barrel 100 to D, the inner diameter of the well seat to d, and the range of the outer diameter D of the barrel 100 to d-20mm to d+30mm, so as to facilitate inserting the first end 110 of the barrel 100 into the well seat with a certain degree of construction error.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
