Description

Technical Field

[0001] This invention belongs to the field of road repair, specifically relating to a method and system for repairing manhole subsidence, and a magnetic rubber leveling manhole cover. Background Technology

[0002] On existing urban roads, manholes are often subjected to tens of tons of pressure, causing the manhole covers to collapse inward under the pressure, resulting in manhole settlement. This causes vehicles to bounce when passing over such settled manholes, creating a vicious cycle of vehicle damage and manhole settlement. It also generates significant traffic noise, greatly damaging the image of urban management and seriously affecting urban traffic safety.

[0003] Existing solutions mainly involve partial repairs, replacement of manhole covers and frames, or overall lifting of manholes. Even with frequent maintenance, road damage caused by manhole settlement continues to emerge, resulting in excessive maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] Example 1:

[0054] like Figure 1 As shown, the methods for repairing well subsidence include:

[0055] S1: Use scanning equipment to detect defects in manholes 100 in a defined road section, and obtain data on the type of manhole 100, manhole cover texture, manhole cover outer diameter, settlement at various points on the outer diameter, and relative elevation of the road surface 200 around the manhole 100.

[0056] In this embodiment, the scanning device can be a drone or an existing handheld specialized device. Defect detection mainly refers to the settlement of the inspection well 100. The type of inspection well 100 can be determined based on its outline and the inscription on its cover. Settlement data at various points on the outer diameter can be obtained by using a camera carried by a drone to fly around the opening of the inspection well 100.

[0057] S2: The data obtained in step S1 are transmitted to a preset computer for summary and analysis. The data to be repaired for the sunken manhole cover 102 and the sunken manhole seat 101 are automatically analyzed and sent to the corresponding processing equipment to produce the corresponding magnetic rubber strip and magnetic rubber leveling manhole cover 1.

[0058] In this embodiment, the sunken manhole cover 102 refers to the original manhole cover of the inspection well 100. The sunken manhole seat 101 refers to the original manhole seat of the inspection well 100. The data to be repaired includes the style, size, and material of the selected repair object. The repair objects mainly include the magnetic rubber leveling manhole cover 1 and the magnetic rubber strip.

[0059] Compared to existing technologies, this invention utilizes a scanning device to acquire information on all inspection wells 100. The scanning device analyzes, filters, and statistically processes the data, which is then quickly transmitted to the processing equipment via the Internet. After receiving the style, size, and material data of the object to be repaired, the processing equipment can quickly and effectively carry out customized production.

[0060] S3: Based on the data to be repaired, use a preset laser etching machine to etch identification marks on the upper surface of the magnetic rubber leveling manhole cover 1.

[0061] In this embodiment, the identification mark can be etched onto the magnetic rubber leveling manhole cover 1 by manual operation of the laser etching machine. Alternatively, a corresponding program can be pre-installed in the laser etching machine to etch the identification mark onto the magnetic rubber leveling manhole cover 1. The identification mark can be a pattern or text.

[0062] Compared to existing technologies, this invention also utilizes a laser etching machine to etch identification marks onto the magnetic rubber leveling manhole cover 1, ensuring that all or part of the information of the magnetic rubber leveling manhole cover 1 is preserved, so as to facilitate identification by maintenance personnel.

[0063] S4: Based on the corresponding magnetic strip and magnetic rubber leveling manhole cover 1, repair the corresponding sunken manhole cover 102 or sunken manhole seat 101.

[0064] In this embodiment, the action of repairing the corresponding sunken manhole cover 102 or sunken manhole seat 101 can be performed manually or by a preset automated device.

[0065] Among them, such as Figure 2 As shown, step S4 includes:

[0066] S41: Based on the settlement data at each point of the outer diameter and the outer diameter data of the manhole cover, as well as the relative elevation of the surrounding road surface 200, determine whether there is only a height difference between the bottom of the sunken manhole cover 102 and the top of the sunken manhole seat 101;

[0067] S42: If so, fix the corresponding magnetic adhesive strip to the pressure-bearing position of the sinkhole seat 101;

[0068] S43: If not, based on the type data of inspection well 100, identify whether the sunken well seat 101 is an upper-bearing or lower-bearing type;

[0069] S44: If the sunken manhole seat 101 is an upper support type, after the top of the sunken manhole seat 101 and the sunken manhole cover 102 are cleaned, install the corresponding hinge device 3 and opening device at the opening of the inspection well 100, and then, based on the height of the manhole cover sinking relative to the road surface 200, hinge the corresponding magnetic rubber leveling manhole cover 1 to the hinge device.

[0070] S45: If the sinkhole seat 101 is a bottom support type, after the top of the sinkhole cover 102 is cleaned, place the corresponding magnetic rubber leveling cover 1 on the top of the sinkhole cover 102.

[0071] In this embodiment, it can be remotely detected whether there is a height difference only between the bottom of the sunken manhole cover 102 and the top of the sunken manhole seat 101 by acquiring photos by drone, or it can be detected manually by special instruments.

[0072] Specifically, through steps S41-S45, the subsided inspection wells can be automatically repaired or assisted by manual repair to improve the efficiency of the repair.

[0073] Compared with existing technologies, steps S41-S45 can effectively reduce additional damage to various components of the inspection well 100, improve the overall lifespan of the inspection well 100, and reduce maintenance costs.

[0074] S5: Use drones and their scanning equipment to conduct regular inspections of the manholes 100 on the repaired road section. If the manhole cover or manhole seat sinks, repeat steps S1-S4.

[0075] Compared to existing technologies, the method of this invention requires the use of drones to periodically inspect the road section after the manholes 100 in the corresponding road section have been repaired, so as to detect and resolve problems in a timely manner.

[0076] In summary, the system of the present invention can use magnetic strips and magnetic rubber leveling covers with a certain degree of elasticity to eliminate the settlement height difference between the manhole cover and the manhole seat, as well as between the manhole cover / manhole seat and the road surface 200, reduce vehicle bouncing, improve driving comfort and safety, and effectively avoid direct contact between the vehicle and the manhole 100 structure, thereby reducing urban noise.

[0077] Example 2:

[0078] Reference Figure 3 Based on Embodiment 1, this example discloses a magnetic rubber leveling manhole cover 1, including a fabric-reinforced rubber panel 11, a stainless steel groove 12, a magnetic block 13, and a metal expansion rivet 14.

[0079] It should be noted in this example that the connection method of the magnetic rubber leveling manhole cover 1 is different for the upper-bearing and lower-bearing inspection wells 100.

[0080] Preferably, the magnetic rubber leveling manhole cover 1 is installed or placed on top of the sunken manhole cover 102 and is slightly higher than the surrounding road.

[0081] Preferably, the magnetic rubber leveling manhole cover 1 is 5mm higher than the surrounding road surface.

[0082] In this embodiment, the inspection well 100 is uniformly settled with a depth of less than 30mm. In the magnetic rubber leveling well cover 1, the stainless steel groove 12 is placed or installed on the top side of the sunken well cover 102. The metal expansion rivet 14 penetrates the stainless steel groove 12 and is fixedly connected to the cloth-reinforced rubber panel 11. The magnetic block 13 is set between the cloth-reinforced rubber panel 11 and the stainless steel groove 12.

[0083] In this embodiment, the magnetic block 13 is a galvanized magnetic block, which has the advantages of corrosion resistance and strong magnetism.

[0084] In this embodiment, multiple magnetic blocks 13 are evenly and spaced apart on the bottom of the fabric-reinforced rubber panel 11 to increase the adsorption force between the stainless steel groove 12 and the sunken manhole cover 102.

[0085] In this embodiment, the stainless steel channel 12 is a galvanized steel plate channel rolled with a thickness of 5mm.

[0086] Preferably, the metal expansion rivet 14 is a general-purpose aluminum alloy product, used to connect the rubber plate and the steel plate groove.

[0087] Specifically, the magnetic rubber leveling manhole cover 1 is a prefabricated component that can be directly placed or installed on the top side of the sunken manhole cover 102.

[0088] Compared with the prior art, the magnetic rubber leveling manhole cover of the present invention is quick to install, easy to replace when damaged or when the height difference needs to be readjusted, and has high applicability. It can be used for manhole covers of 100mm diameter and different degrees of subsidence in inspection wells.

[0089] Example 3:

[0090] Reference Figure 4 Based on Embodiment 1, this example discloses a magnetic rubber leveling manhole cover 1, applied to an upper-bearing manhole base. The magnetic rubber leveling manhole cover 1 includes a switching device 2 and a hinge device 3. In this embodiment, when the sunken manhole cover 102 or manhole base 101 experiences uneven settlement relative to the surrounding road, the prefabricated magnetic rubber leveling manhole cover 1 is composed of a fabric-reinforced rubber panel 11, a perforated rubber plate 15, a stainless steel groove 12, a magnetic block 13, metal expansion rivets 14, and an adhesive 16.

[0091] The perforated rubber sheet 15 is placed or installed on the top side of the sunken manhole cover 102. A stainless steel groove 12 is located on the top side of the perforated rubber sheet 15, and a fabric-reinforced rubber panel 11 is located on the top side of the stainless steel groove 12. Adhesive 16 is disposed between the stainless steel groove 12 and the fabric-reinforced rubber panel 11. Metal expansion rivets 14 penetrate the perforated rubber sheet 15 and the stainless steel groove 12, connecting to the fabric-reinforced rubber panel 11. A magnetic block 13 is disposed between the perforated rubber sheet 15 and the sunken manhole cover 102.

[0092] In this embodiment, the magnetic block 13 is also a galvanized magnetic block.

[0094] In this embodiment, the magnetic rubber leveling manhole cover is divided into two symmetrical parts to facilitate the maintenance of the inspection well 100.

[0095] In this embodiment, the switch device 2 is located on the top side of the two fabric-reinforced rubber panels 11, and is used to lock or open the two magnetic rubber leveling manhole covers. The hinge device is located on the manhole base 101.

[0096] In this embodiment, adhesive 16 is TY-51 engineering structural adhesive from Tianyu Company. This structural adhesive has the characteristics of fast curing speed, good penetration, strong adhesion, good toughness, high and low temperature resistance, and impact resistance. It can form a certain degree of chemical bond with concrete substrates, cast iron surfaces, glass surfaces, rubber and plastic sheets to form a strong coating film. It has the advantages of super strong adhesion, strong corrosion resistance, good weather resistance, and simple and quick construction.

[0097] In this embodiment, adhesive 16 is butyl rubber. Butyl rubber has good mechanical properties, including high bonding strength, high tensile strength, good elasticity and elongation, and can maintain flexibility. It is highly adaptable to interface deformation and cracking and can withstand a certain degree of displacement. In addition, it has stable chemical properties, waterproof sealing and chemical corrosion resistance, strong UV resistance, and good low-temperature resistance.

The thickness of the panel is sufficient to eliminate the height difference of the well cover settlement.

[0101] Option 2: When the maximum settlement depth of the inspection well 100 is between 50mm and 80mm, after adjusting the slope using a porous rubber sheet 15, a cloth-reinforced rubber panel 11 and a steel plate groove 16 are used to cover the sunken well base 101 and well cover 102.

[0102] Option 3: When the maximum outer diameter of the inspection well exceeds 80mm, divide the magnetic rubber leveling cover into two equal parts and install a hinge device and an opening device. Other procedures are the same as in Option 2.
