Description

Technical Field

[0001] The utility model relates to the technical field of municipal road inspection wells, in particular to a municipal road inspection well structure for preventing subsidence. Background Art

[0002] Municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns, and provide paid or free public products and services to residents based on government responsibilities and obligations. Among them, urban roads serve the internal system of the city, also known as municipal roads. Municipal roads are roads within the urban area. Municipal road inspection wells are set up for the maintenance of power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, street light lines and other urban underground infrastructure, and are easy to install. They are generally located at pipeline intersections, bends, changes in pipe diameter or slope, and at certain intervals on straight pipe sections to facilitate regular inspection of ancillary structures.

[0003] The existing patent (Announcement No.: CN202320670415.4) discloses a municipal road inspection well for preventing subsidence. The setting of the connecting ring can increase the force-bearing area, thereby preventing the connecting tube and the wellbore from sinking. The opening of the slide groove facilitates the limiting of the connecting tube, so that the connecting tube will not deviate when it sinks under pressure. The action of the spring can relieve the pressure of the connecting tube on the wellbore to a certain extent, and at the same time, it can provide a certain support for the connecting tube, leaving a certain amount of settlement space for the connecting tube, thereby reducing the possibility of wellbore settlement. At the same time, the setting of the support plate can support the wellbore. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved:

[0004] This solution achieves the anti-sinking effect by supporting the manhole cover with a spring, but the spring itself is prone to deformation during long-term squeezing and does not have a good anti-sinking effect. In addition, when the spring itself is damaged, it is difficult to repair and cannot be used for a long time. Utility Model Content

[0005] In order to improve the problem that the above-mentioned spring is easily deformed during long-term extrusion and cannot effectively prevent subsidence, the utility model provides a municipal road inspection well structure for preventing subsidence.

[0006] The utility model provides a municipal road inspection well structure for preventing subsidence, which adopts the following technical solutions:

[0009] Through the above technical scheme, it is convenient to share the pressure on the manhole cover body through the cooperation of the auxiliary block and the extension block, and distribute it as a whole to the surrounding areas of the ground, thereby reducing the probability of settlement of the manhole cover body. Secondly, by providing two symmetrically distributed top plates, when settlement occurs around, the top plate is squeezed to make the top plate on the other side provide auxiliary support to ensure the safety of the top plate.

[0013] Through the above technical solution, it is convenient to fix the fixed block through the wellbore, which facilitates the subsequent secondary anti-subsidence work.

[0014] Optionally, in the above-mentioned municipal road inspection well structure for preventing subsidence, the auxiliary block is in an "L"-shaped structure, the auxiliary block and the anti-sinking block are connected by hot-melt connection, and the anti-sinking block and the auxiliary block form a "T"-shaped structure.

[0015] Through the above technical solution, it is convenient to use the auxiliary block and the anti-sinking block to transmit the pressure of the extension block and the manhole cover body to the bottom, so as to avoid the manhole cover body from sinking due to excessive pressure.

[0016] Optionally, in the above-mentioned municipal road inspection well structure for preventing subsidence, linkage blocks are evenly and equidistantly distributed inside the fixed block, the linkage block is connected to the fixed block by concrete pouring, and an arc-shaped groove is opened in the center of the linkage block.

[0022] In summary, the present invention has at least one of the following beneficial effects:

[0023] By arranging an extension block and an anti-sinking block under the main body of the manhole cover, the main body of the manhole cover distributes the pressure to the anti-sinking block and the auxiliary block when pressed by a vehicle, thereby reducing the pressure on the main body of the manhole cover and preventing the main body of the manhole cover from sinking during use. Secondly, the anti-sinking block and the auxiliary block form a T-shaped structure, and the auxiliary block is an L-shaped structure, which increases the contact surface with the ground and prevents sinking around.

[0024] By arranging a support block and a linkage block under the manhole cover body, when the manhole cover body is about to sink, the support block squeezes the top plate, causing the top plate on the other side to rise, thereby supporting the manhole cover body. At the same time, the linkage block and the fixed block further share the pressure in the center of the manhole cover body, so that the central area will not sink. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-4 The utility model is described in further detail.

[0031] Please refer to the attached figure in the instruction manual Figure 1-4 The utility model provides an embodiment: a municipal road inspection well structure for preventing subsidence, comprising an extension block 5 connected to the bottom of the well cover body 1, an auxiliary block 6 is arranged below the extension block 5, the extension block 5 is supported by the auxiliary block 6 and the extension block 5, an anti-sinking block 7 is connected below the auxiliary block 6, the well cover body 1 is located above the ground 4, the anti-sinking block 7 is used to distribute the pressure of the well cover body 1 to the ground 4 to prevent the edge from subsiding, and a well shaft 3 is arranged below the well cover body 1;

[0032] The fixed block 8 is internally connected to a linkage block 9, which is used to share the pressure in the central area with the fixed block 8 to prevent the center from settling. The linkage block 9 is internally connected to a sliding rod 10, and a bearing ball 11 is arranged below the sliding rod 10. The bearing ball 11 is used to drive the sliding rod 10 to rise and fall toward both sides to ensure its ease of use. A top plate 12 is connected above the sliding rod 10, and a support block 2 is arranged above the top plate 12. The support block 2 is adsorbed by the top plate 12 to prevent its shaking from causing shaking of the manhole cover body 1, and an adsorption magnet 13 is connected to the bottom of the support block 2.

[0033] See the attached drawings in the specification Figure 1-4 The connection between the manhole cover body 1 and the extension block 5 is a hot-melt connection. The extension block 5 is in a circular ring shape. The extension block 5 fits tightly on top of the auxiliary block 6. The extension block 5 distributes the pressure of the manhole cover body 1 to reduce its probability of settlement.

[0034] See the attached drawings in the specification Figure 1-4 The wellbore 3 is in a circular ring structure. The wellbore 3 is evenly and equidistantly distributed inside the ground 4. Fixed blocks 8 are evenly and equidistantly distributed outside the wellbore 3. The fixed blocks 8 are fixed by the wellbore 3 to facilitate the subsequent secondary anti-subsidence work.

[0035] See the attached drawings in the specification Figure 1-4 The auxiliary block 6 is in an "L"-shaped structure. The auxiliary block 6 and the anti-sinking block 7 are connected by hot-melt connection. The anti-sinking block 7 and the auxiliary block 6 form a "T"-shaped structure. The auxiliary block 6 and the anti-sinking block 7 cooperate to transmit the pressure of the extension block 5 and the manhole cover body 1 to the bottom, thereby avoiding the manhole cover body 1 from sinking due to excessive pressure.

[0036] See the attached drawings in the specification Figure 1-4 The linkage blocks 9 are evenly and equidistantly distributed inside the fixed block 8. The linkage blocks 9 are connected to the fixed block 8 by concrete pouring. An arc groove is opened in the center of the linkage block 9. The fixed block 8 cooperates with the linkage block 9 to provide auxiliary support for the linkage block 9 to ensure that the linkage block 9 will not be deformed due to excessive pressure.

[0037] See the attached drawings in the specification Figure 1-4 Bearing beads 11 are evenly and equidistantly distributed at the center of the linkage block 9, and sliding rods 10 are symmetrically distributed on both sides of the bearing beads 11. The sliding rods 10 and the top plate 12 are installed in an integrated manner. Through the cooperation between the linkage block 9 and the bearing beads 11, the top plate 12 and the sliding rods 10 can provide auxiliary support to the support block 2 to ensure that the support block 2 will not sink.

[0038] See the attached drawings in the specification Figure 1-4 The top plate 12 fits tightly against the support block 2, and adsorption magnets 13 are evenly and equidistantly distributed inside the support block 2. The adsorption magnets 13 and the top plate 12 are adsorbed on each other. The top plate 12 cooperates with the adsorption magnets 13 to prevent the support block 2 from shaking and deviating, which would affect subsequent use.

[0039] Working principle: When using the municipal road inspection well structure for preventing subsidence, first, during use, when a vehicle passes through the manhole cover body 1, pressure is applied to the manhole cover body 1, and the pressure on the edge of the manhole cover body 1 is distributed to the auxiliary block 6 by the extension block 5. The auxiliary block 6 then cooperates with the anti-sinking block 7 to evenly distribute the pressure to the surrounding ground 4, preventing the manhole cover body 1 and the extension block 5 below it from sinking;

[0040] As mentioned above, when a vehicle passes through the center of the manhole cover body 1, if the manhole cover body 1 is about to sink, it drives the support block 2 to descend, and the support block 2 presses against the top plate 12. The rear top plate 12 squeezes the bearing ball 11 through the sliding rod 10, so that the top plate 12 on the other side rises, thereby supporting the support block 2. As the vehicle passes by, the top plate 12 in the center area begins to descend, while the top plate 12 on the other side rises again, ensuring that the supporting force of the support block 2 changes as the center of gravity changes when the vehicle passes. At the same time, the linkage block 9 disperses the pressure from the fixed block 8 to prevent the linkage block 9 from deforming.

[0041] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
