DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides a technical solution, such as Figure 1-Figure 3 As shown; a maintenance well structure for rapid maintenance of municipal roads, comprising: an inspection well section 1, arranged below the road and spaced a certain height from the road surface, with a regular hexagonal boss 11 provided at its upper end: a replacement groove 2, opened on the upper outer side of the inspection well section 1, with a replacement cylinder seat 21 embedded inside, and the lower end of the replacement cylinder seat 21 is sleeved on the inspection well section 1.

[0028] In the embodiment of the utility model, the setting of the regular hexagonal boss 11 at the upper end of the inspection well section 1 can enable the precast concrete well ring 3 to be quickly inserted into the inspection well section 1 and prevent it from rotating, so that the precast concrete well ring 3 can utilize its own gravity to be stably placed in the replacement groove 2, making the inspection well maintenance more convenient and faster.

[0029] In the embodiment of the present invention, the setting of the replacement groove 2 is utilized so that when the inspection manhole cover 32 is damaged or the asphalt pavement around it is damaged and needs to be replaced, the staff can directly lift out the precast concrete well ring 3, the inspection manhole cover 32, the outer base 4, and the precast asphalt surface layer 5 as a whole, thereby facilitating the replacement of the new inspection manhole structure.

[0030] The precast concrete well ring 3 is arranged above the inspection well section 1, and a regular hexagonal groove 31 is opened at its lower end. The regular hexagonal groove 31 is mounted on the upper end of the inspection well section 1, and an inspection well cover 32 is installed at its upper end. The inner wall side surface is provided with lifting grooves 33, which are evenly distributed. U-shaped reinforcement ribs 34 are installed in the lifting grooves 33, and the U-shaped reinforcement ribs 34 extend out of the precast concrete well ring 3; the outer base 4 is arranged below the outer surface of the precast concrete well ring 3 and embedded in the precast concrete well ring 3, and is connected to the U-shaped reinforcement ribs 34. Short reinforcement ribs 41 are arranged inside it, and the short reinforcement ribs 41 are vertically evenly distributed and connected to the outer base 4 and the U-shaped reinforcement ribs 34. Inorganic binder 42 is filled inside it; the precast asphalt surface layer 5 is arranged above the outer base 4 and the precast concrete well ring 3, and wraps the inspection well cover 32. Its thickness is the same as that of the road asphalt surface layer.

[0031] In the embodiment of the present invention, the regular hexagonal groove 31 provided at the lower end of the precast concrete well ring 3 can be used to quickly connect the well ring with the inspection well section 1, and ensure the firmness of the connection to avoid shaking.

[0032] In the embodiment of the utility model, the lifting groove 33 and the U-shaped reinforcement rib 34 are arranged so that the lifting hook can be quickly mounted on the U-shaped reinforcement rib 34, thereby facilitating the lifting of the entire device, and the inspection well structure can be quickly disassembled and installed through lifting, making the operation more convenient and quick.

[0033] In the embodiment of the present invention, the provision of the U-shaped reinforcement ribs 34 can make the connection between the outer base 4 and the precast concrete well ring 3 more stable, ensure the safety of the device hoisting, avoid leakage of the inorganic binder 42, and by providing the reinforcement short ribs 41, the outer base 4 is fixed more firmly to avoid deformation.

[0034] In the embodiment of the present invention, the prefabricated asphalt surface layer 5 is directly prefabricated above the inorganic binder 42 and the prefabricated concrete well ring 3, so that the road surface can be directly passed after the inspection well is repaired, avoiding the collapse of the asphalt surface layer 5 due to vehicle rolling, and improving maintenance efficiency.

[0035] In the embodiment of the present invention, the thickness of the prefabricated asphalt surface layer 5 is the same as the thickness of the asphalt surface layer of the road surface. At the same time, the size of the prefabricated asphalt surface layer 5 is the same as the outer diameter of the outer base 4, so that the entire device can be embedded in the replacement groove 2, making the inspection well maintenance faster and more convenient.

[0036] In the present invention, the outer base 4 is embedded in the replacement cartridge seat 21 in the replacement slot 2, making the device replacement more efficient and stable.

[0037] In the present invention, the upper end of the outer base 4 is flush with the upper surface of the road base, thereby ensuring that the prefabricated asphalt surface layer 5 is aligned with the asphalt surface layer of the road.

[0038] In the present invention, there is a certain gap between the outer side of the prefabricated asphalt surface layer 5 and the inner wall of the replacement groove 2, the gap width is the same as the wall thickness of the replacement cylinder seat 21, and modified asphalt 6 is filled therein; by filling the modified asphalt 6, its fluidity can be utilized to fill the gap, thereby ensuring the flatness of the road surface, and at the same time, the prefabricated asphalt surface layer 5 can be quickly connected with the road asphalt surface layer.

[0039] In the present invention, the same short reinforcement ribs 41 are installed between the U-shaped reinforcement ribs 34 and correspond to the positions of the short reinforcement ribs 41 between the outer base 4 and the U-shaped reinforcement ribs 34 , thereby improving the connection strength of the outer base 4 .

[0040] In the present invention, the upper surface of the prefabricated asphalt surface layer 5 and the upper surface of the inspection well cover 32 are on the same horizontal plane, ensuring the flatness of the road surface after the inspection well is replaced.

[0041] When using the utility model, the staff opens the manhole cover and inserts the lifting hook into the manhole so that it is hung on the U-shaped reinforcement rib 34 in the lifting groove 33. Then, the staff uses the lifting equipment to drag the damaged manhole structure upward, thereby lifting it together with the outer base 4 and the broken prefabricated asphalt surface layer 5, and then lifts it out of the replacement tank 2 and hoisted it onto the transportation equipment.

[0042] Then the staff removes the hook, opens the manhole cover 32 of the new manhole structure, inserts the hook into it, and then hangs it on the U-shaped reinforcement rib 34 in the internal lifting groove 33. Then, the new manhole structure is hoisted into the replacement groove 2 by using the lifting equipment, and the outer base 4 is embedded in the replacement cylinder seat 21. At the same time, during the hoisting process, the new manhole structure is rotated so that the regular hexagonal groove 31 at the lower end of the precast concrete well ring 3 is aligned with the regular hexagonal boss 11 of the manhole section 1. Then, the new manhole structure is controlled to descend so that the precast concrete well ring 3 is fitted onto the manhole section 1.

[0043] At this time, the upper surface of the prefabricated asphalt surface layer 5 is aligned with the upper end of the asphalt surface layer of the road surface. The staff takes out the modified asphalt, fills it into the gap between the prefabricated asphalt surface layer 5 and the asphalt surface layer of the road surface, and smoothes it.

[0044] When the inspection well structure is manufactured, the outer base 4 and the U-shaped reinforcement ribs 34 are cast inside the precast concrete well ring 3 when the precast concrete well ring 3 is cast in the mold, so that the outer base 4 and the U-shaped reinforcement ribs 34 are fixed together with the precast concrete well ring 3. Subsequently, the short reinforcement ribs 41 are welded and welded between the U-shaped reinforcement ribs 34 and between the U-shaped reinforcement ribs 34 and the outer base 4.

[0045] Then, it is hoisted into a prefabricated trough set on the ground, and the inorganic binder 42 is filled into the outer base 4 and compacted, and then a prefabricated asphalt surface layer 5 is laid on it and wrapped around the inspection well cover 32.
