Description

Technical Field

[0001] The utility model relates to a sewer manhole cover, and more specifically, mainly relates to a self-supporting anti-sinking manhole cover installation structure. Background Art

[0002] With the acceleration of urbanization in my country, municipal infrastructure, especially urban road construction, has developed rapidly. Sewer manhole covers are widely used in municipal engineering, especially in the reconstruction of old urban roads. Due to problems in products, design, construction and use, sewer manhole covers have a large number of quality problems such as overall sinking of the manhole cover, internal sinking, cracking around the well, and bulging of the manhole cover. Especially for the manhole covers used on the main road, if there is sinking, it will cause problems such as vehicle jumping, abnormal noise of the manhole cover, and manhole cover falling off when passing by, which seriously affects driving comfort and safety, and also causes noise nuisance to the public, but it is a "pain point" problem in the city that has not been solved. The currently widely used adjustable anti-sinking manhole covers are developed on the basis of traditional manhole covers. The flange surface is added to increase the pressure area of ​​the manhole cover and reduce the amount of settlement. It is a general trend in the development of manhole covers, and there are many related research results. However, in the actual application process, there are still a lot of problems such as overall sinking, large height difference between the manhole cover and the road surface, and internal settlement of the manhole cover. In summary, the main reasons why adjustable anti-sinking manhole covers still have these problems on a large scale are: the quality problem of the overall sinking of the manhole cover is caused by the asphalt mixture under the flange surface not being fully compacted; the problem of the height difference between the manhole cover and the road surface not meeting the requirements of the specification is caused by the inability to accurately measure the amount of asphalt mixture stuffed under the flange surface; and the internal settlement of the manhole cover is caused by the aging and deformation of the rubber strip inside the manhole cover. Therefore, it is necessary to study and improve the structure of the above-mentioned manhole covers. Utility Model Content

[0003] One of the purposes of the present utility model is to provide a self-supporting anti-sinking manhole cover installation structure in view of the above-mentioned deficiencies, in the hope of solving the technical problems that similar manhole covers in the prior art are prone to overall sinking, especially the sinking of manhole covers used on roads, which easily affects the passability of vehicles.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model provides a self-supporting anti-sinking manhole cover installation structure, comprising a manhole cover body and a supporting cylinder, wherein the manhole cover body is installed on the upper part of the supporting cylinder and is flush with the road surface, the supporting cylinder is sleeved on the outside of the shaft, and the side of the supporting cylinder is also provided with at least two supporting cross beams, the outer ends of the supporting cross beams are embedded in concrete supporting blocks, and the concrete supporting blocks are placed in the slag on the side of the shaft, and the density of the slag below the concrete supporting blocks is greater than the density of the slag on the side of the shaft.

[0006] Preferably, a further technical solution is: a supporting edge is provided on the inner wall of the supporting cylinder, and the supporting edge is placed above the well opening.

[0007] A further technical solution is: a rubber ring with a C-shaped longitudinal section and an outward opening is provided on the supporting edge, and the outer edge of the manhole cover body is used to be embedded in the outward opening of the rubber ring.

[0008] A further technical solution is: a slot is provided on the concrete support block, and a block body corresponding to the slot is provided on the outer end of the support beam on the support cylinder, and the block body is used to engage into the slot from the upper part of the concrete support block.

[0009] A further technical solution is that the well is placed near the middle of the road surface and is connected to an underground drainage channel.

[0010] Compared with the prior art, one of the beneficial effects of the present invention is that by adding a supporting cylinder installed on the outside of the shaft, and fixing the cylinder on the concrete supporting block through a supporting crossbeam, and the concrete supporting block is fixed on the compacted slag, a stronger supporting effect can be provided to the installation position of the manhole cover body, thereby preventing it from sinking due to repeated rolling by vehicles during use. It is particularly suitable for installation and use on the manhole in the middle of the road. At the same time, the self-supporting anti-sinking manhole cover installation structure provided by the present invention is simple and easy to operate, and can be installed and used on shafts of various specifications, with a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram for illustrating an embodiment of the utility model.

[0012] Figure 2 It is a partially enlarged view for illustrating the installation position of the manhole cover body in another embodiment of the utility model.

[0013] In the figure, 1 is the manhole cover body, 2 is the supporting cylinder, 3 is the shaft, 4 is the supporting beam, 5 is the concrete supporting block, 6 is the supporting edge, and 7 is the rubber ring. DETAILED DESCRIPTION

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] refer to Figure 1As shown, one embodiment of the utility model is a self-supporting anti-settling manhole cover installation structure, including a manhole cover body 1 and a supporting cylinder 2. The manhole cover body 1 is installed on the upper part of the supporting cylinder 2 and is flush with the road surface. The aforementioned supporting cylinder 2 needs to be sleeved on the outside of the shaft 3. More importantly, at least two supporting beams 4 need to be designed on the side of the aforementioned supporting cylinder 2. The supporting beams 4 can be welded to the supporting cylinder 2 or detachably fixed to the supporting cylinder 2 by buckles, and the outer ends of the supporting beams 4 are embedded in concrete supporting blocks 5, and the concrete supporting blocks 5 are placed in the slag on the side of the shaft 3, and the slag located at the bottom of the concrete supporting blocks 5 needs to be compacted in advance. Figure 1 As shown in the middle A area, it has a strong supporting force to prevent the concrete support block 5 from sinking due to long-term pressure, thereby causing the manhole cover 1 to sink. Therefore, before the manhole cover structure is installed, the lower slag needs to be compacted in advance, that is, the density of the slag below the concrete support block 5 should be much greater than the density of the slag on the side of the well 3. After the slag is compacted, the supporting force that the slag can provide should generally be much greater than the pressure on the manhole cover 1 during use. The aforementioned well 3 can be set near the middle of the road surface and connected to the underground drainage channel.

[0016] In this embodiment, by adding a supporting cylinder 2 installed on the outside of the shaft, and fixing the supporting cylinder 2 on the concrete supporting block 5 through the supporting crossbeam 4, and the concrete supporting block 5 is fixed on the compacted debris, it can provide a stronger support for the installation position of the manhole cover body 1, avoiding its settlement caused by repeated rolling by vehicles during use, and is particularly suitable for installation and use in a manhole in the middle of a wider road.

[0017] Preferably, in order to facilitate the installation of the manhole cover body 1, an annular supporting edge 6 can be directly provided on the inner wall of the supporting cylinder 2, and the supporting edge is placed above the well 3 opening, and then the manhole cover body 1 can be directly placed on the aforementioned supporting edge 6 to complete the installation. Figure 2 As shown, in order to ensure the sealing performance of the manhole cover body 1 after installation, a rubber ring 7 with a C-shaped longitudinal section and an outward opening can be added to the supporting edge 6, so that the outer edge of the manhole cover body 1 can be embedded in the outward opening of the rubber ring 7. The rubber ring 7 can not only make the manhole cover body 1 sealed, but also play a certain buffering role between the annular supporting edge 6 and the lower part of the manhole cover body 1, further improving the settlement problem caused by the manhole cover body 1 being rolled.

[0018] On the other hand, to facilitate installation, the end of the above-mentioned supporting beam 4 and the concrete supporting block 5 can be designed as a detachable installation structure. For example, in the present embodiment, a slot is added to the above-mentioned concrete supporting block 5, and then a block body corresponding to the slot is added to the outer end of the supporting beam 4 on the supporting cylinder 2. The outer end of the supporting beam 4 can be fixed to the concrete supporting block 5 by engaging the block body from the upper part of the concrete supporting block 5 into the slot, so that the supporting cylinder 2 and the concrete supporting block 5 form a self-supporting structure.

[0019] refer to Figure 1 As shown, in actual use of the above preferred embodiment of the utility model, first, when designing the pavement, determine the position of the sewer manhole, and then, during the construction process, pre-bury the concrete support block 5 in the slag around the sewer manhole, and at the same time, compact the slag below the concrete support block 5 to give it a strong supporting force. After the concrete support block 5 is pre-buried and the manhole is processed, the overall support cylinder 2 is placed from top to bottom along the outer edge of the shaft 3. When the support cylinder 2 is lowered to the specified position, the outer end of the support beam 4 is fixed on the concrete support block 5 to form a self-supporting structure, and then the manhole cover body 1 is placed on the support edge 6 on the inner wall of the support cylinder 2 to complete the installation of the self-supporting anti-settling manhole cover.
