At present, when the road surface around the inspection well has a large traffic load, the road surface around the inspection well often suffers from subsidence, so it is often necessary to renovate the road surface around the inspection well. In the renovation construction of the road surface around the inspection well, the ground around the manhole cover is first excavated to form a renovation foundation pit. After the well seat and the manhole cover ring seat are replaced and re-elevated, asphalt concrete is re-poured in the renovation foundation pit, and the renovation foundation pit is filled and repaired to form a new road surface. The above renovation process is simple, and the service life of the road surface around the inspection well after renovation is low, and there is room for optimization. Summary of the invention

[0004] In order to increase the service life of the road surface around the refurbished inspection well, one of the purposes of the present application is to provide a road surface reinforcement structure around the inspection well.

[0006] By adopting the above technical scheme, a reinforced casing is added in the renovated foundation pit, and a reinforcing component is arranged between the reinforced casing and the renovated well seat. On the one hand, the contact area between the renovated well seat and the soil layer is increased, and the anti-subsidence performance of the renovated well seat is improved. On the other hand, the reinforcing component supports and reinforces the road surface around the inspection well, thereby reducing the possibility of collapse of the road surface around the renovated inspection well and improving the service life of the road surface around the renovated inspection well.

[0007] Preferably, guide holes are radially penetrated through the circumferential wall of the reinforced casing, and a plurality of guide holes are provided and distributed along the circumference of the reinforced casing. Reinforcement holes corresponding to the positions of the guide holes are provided on the inner circumferential wall of the renovation foundation pit. The reinforcement assembly includes a reinforcement tube arranged on the renovation well seat and a reinforcement rod slidably connected to the reinforcement tube, and the ends of the reinforcement rod are successively passed through the guide hole and the reinforcement hole.

[0008] By adopting the above technical solution, after the renovation well seat and the reinforced casing are installed, the reinforcement rod is slid so that the ends of the reinforcement rod are successively passed through the guide hole and the reinforcement hole, and the reinforcement rod is inserted into the old concrete layer, so that the renovation well seat and the surrounding pavement structure layer form a solid and stable body, reducing the possibility of displacement of the renovation well seat due to mechanical rolling load, and further reducing the possibility of sinking displacement of the inspection well and subsidence of the road surface around the inspection well.

[0009] Preferably, a protective ring groove is opened on the upper part of the renovation foundation pit, and the protective ring groove is located above the reinforcement hole. The upper part of the reinforcement casing is protrudingly provided with a protective ring plate embedded in the protective ring groove.

[0010] By adopting the above technical solution, a protective ring plate is added, and after the reinforced casing is placed in the renovation pit, the outer peripheral wall of the reinforced casing abuts against the inner peripheral wall of the renovation pit, and the protective ring plate of the reinforced casing abuts against the bottom inner wall of the protective ring groove. The staff uses a handheld drilling equipment to drill the peripheral wall of the renovation pit through the guide hole to form a reinforced hole. The protective ring plate presses the soil above the reinforced hole to reduce the possibility of collapse of the soil around the renovation pit due to the drilling operation.

[0011] Preferably, a sliding ring cavity is axially opened on the lower end face of the reinforced casing, a supporting ring plate is arranged below the reinforced casing, the upper end face of the supporting ring plate is fixedly connected with a sliding ring plate slidably inserted in the sliding ring cavity, the lower end face of the supporting ring plate abuts against the bottom inner wall of the renovation foundation pit, and the reinforced casing is provided with an adjusting part for adjusting the sliding position of the sliding ring plate.

[0012] By adopting the above technical solution, the position of the sliding ring plate in the sliding ring cavity is adjusted by the adjusting member, thereby adjusting the height position of the reinforcing casing, thereby adjusting the height position of the guide hole, so that the guide hole and the reinforcing rod are at the same height position, thereby improving the convenience of the reinforcing rod threading operation.

[0013] Preferably, the lower end surface of the reinforcing rod is provided with a slot for clamping the bottom inner wall of the guide hole, and a casting gap is provided between the protective ring plate and the inner peripheral wall of the protective ring groove. When the bottom inner wall of the guide hole is clamped in the slot, a casting gap is provided between the protective ring plate and the bottom inner wall of the protective ring groove.

[0014] By adopting the above technical scheme, after the renovation of the well seat and the reinforcement casing are installed, the sliding reinforcement rod is made so that the ends of the reinforcement rod are successively inserted into the guide hole and the reinforcement hole, and the reinforcement casing is driven to move up relative to the sliding ring plate through the adjusting member. On the one hand, the bottom inner wall of the guide hole is embedded in the card groove, which effectively reduces the possibility of the reinforcement rod sliding back and out of the reinforcement hole. On the other hand, there is a casting gap between the bottom inner wall of the protective ring plate and the protective ring groove. The staff fills the bonding liquid through the casting gap between the protective ring plate and the inner peripheral wall of the protective ring groove. The bonding liquid flows into and fills the casting gap between the protective ring plate and the bottom inner wall of the protective ring groove, thereby repairing / reinforcing the soil around the renovation foundation pit and fixing the reinforcement casing.

[0015] Preferably, the reinforced casing has an installation cavity located above the guide hole and connected to the guide hole, the reinforced casing is provided with a blocking block which is connected to the installation cavity by sliding along the axial direction of the reinforced casing, the reinforced casing is provided with an elastic member built into the installation cavity to force the blocking block to normally slide and retract into the installation cavity, a linkage member is provided between the blocking block and the sliding ring plate, and when the reinforced casing moves up relative to the support ring plate, the blocking block is driven to move downward relative to the reinforced casing through the linkage member.

[0016] By adopting the above technical scheme, under normal conditions, the elastic member forces the blocking block to slide and retract into the installation cavity, thereby improving the convenience of the reinforcing rod insertion operation and the convenience of the drilling operation on the renovation of the foundation pit wall. After the ends of the reinforcing rod are successively inserted into the guide hole and the reinforcing hole, the reinforcing casing is driven to move up relative to the sliding ring plate through the adjusting member, so that the bottom inner wall of the guide hole is embedded in the groove, and in the process of the reinforcing casing moving up relative to the sliding ring plate, the sliding ring plate drives the blocking block to move down relative to the reinforcing casing through the linkage member, so that the lower end face of the blocking block abuts against the upper end face of the reinforcing rod, so that the blocking block blocks the gap between the reinforcing rod and the top inner wall of the guide hole, effectively reducing the possibility of waste caused by the bonding liquid flowing out through the gap between the outer peripheral wall of the reinforcing casing and the inner peripheral wall of the renovation foundation pit and the guide hole in turn, facilitating the bonding liquid to flow into the reinforcing hole, so that the reinforcing rod and the old soil are fixed as one.

[0017] Preferably, a slide groove is provided on the inner wall of the installation cavity, and the slide groove is connected to the inner wall of the guide hole.

The linkage part is a linkage rope passed through the rope threading hole, one end of the linkage rope is fixedly connected to the first slider, and the other end of the linkage rope is fixedly connected to the sliding ring plate.

[0018] By adopting the above technical solution, when the reinforcing casing moves up relative to the sliding ring plate, the sliding ring plate pulls the blocking block downward relative to the reinforcing casing through the linkage rope, so that the lower end surface of the blocking block abuts against the upper end surface of the reinforcing rod.

[0019] Preferably, the reinforcement assembly further comprises a metal rib mesh arranged on the reinforcement tube and the reinforcement rod.

[0020] By adopting the above technical solution and adding metal mesh, on the one hand, the metal mesh can effectively absorb the tensile stress inside the asphalt concrete, delay the occurrence of cracks such as reflection, temperature and differential settlement, thereby reducing the risk of cracking in the renovated road surface; on the other hand, it can improve the tensile and shear strength of the asphalt concrete layer structure, making the road surface structure more stable; on the other hand, the metal mesh can limit the displacement of asphalt concrete aggregates and reduce the rutting deformation of the asphalt concrete surface layer, thereby extending the service life of the road surface.

[0021] Preferably, the upper end surfaces of the reinforcing tube and the reinforcing rod are penetrated with mounting holes, the metal mesh is protrudingly fixed with mounting screws inserted in the mounting holes, and the ends of the mounting screws are threadedly connected with anti-slip nuts.

[0022] By adopting the above technical solution, after the renovation of the well seat and the reinforced casing are installed, the reinforcing rod is slid so that the ends of the reinforcing rod are successively inserted into the guide hole and the reinforcement hole, and the installation screws on the metal mesh are respectively inserted into the installation holes on the reinforcing pipe and the reinforcing rod, and locked with anti-slip nuts to achieve the fixation of the metal mesh.

[0023] In order to increase the service life of the road surface around the refurbished inspection well, the second purpose of the present application is to provide a method for reinforcing the road surface reinforcement structure around the inspection well.

On the one hand, the contact area between the renovation well seat and the soil layer is increased to improve the anti-settling performance of the renovation well seat.
