Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering, and particularly relates to an anti-settlement structure of a precast inspection well. Background Art

[0002] An inspection well is provided for the convenience of maintenance or installation of power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipe, street lamp lines and other urban underground infrastructure. It is generally set at the pipe intersection, turning point, pipe diameter or slope change point, and at certain intervals on the straight pipe section. It is an auxiliary structure convenient for regular inspection.

[0003] In the existing inspection well, a well seat is generally precast inside the wellhead, and then the well cover is covered on the wellhead. In this way, the bearing capacity of the well cover will be all concentrated on the well seat. Due to the soil quality of the road surface, under the long-term rolling of vehicles, the well seat foundation is prone to collapse and settlement, resulting in the settlement of the connection part of the inspection well cover. This not only affects the driving comfort but also further aggravates the damage of the road structure. Summary of the Utility Model

[0004] The utility model provides an anti-settlement structure of a precast inspection well with high stability, easy installation and disassembly, and strong anti-settlement ability to solve the deficiencies of the prior art.

[0005] To achieve the above object, the utility model first proposes an anti-settlement structure of a precast inspection well, which includes an inspection well base. A plurality of insertion openings are symmetrically arranged at the center of the outer side of the inspection well base, and an anchor plate is installed in each insertion opening on the outer side of the inspection well base; the anchor plates are arranged radially along the inspection well base, and a plug pin matching the size of the insertion opening is provided at one end of the anchor plate. A locking assembly for locking the plug pin is installed in the inspection well base. After the plug pin of the anchor plate is inserted into the insertion opening, the plug pin is locked with the inspection well base through the locking assembly, so as to detachably fix the anchor plate on the inspection well base.

[0006] During the installation of the utility model, the anchor plate is inserted inside the insertion opening and fixed through the locking assembly. Through the plurality of anchor plates on the outer side of the inspection well base, the contact area between the inspection well base and the foundation is increased, and the force in the vertical direction is more balanced, thereby preventing the inspection well from settling; at the same time, during transportation, the inspection well base and the anchor plate can be disassembled, which is convenient for transportation.

[0007] In this embodiment, one end of the bolt that extends into the inspection well base is the locking end. A clamping groove is formed on the locking end of the bolt along the circumferential direction of the bolt. The locking assembly includes a plug board larger than the insertion opening. A slot is provided on the plug board, which matches the cross-sectional size of the position where the clamping groove on the bolt is located. A threaded hole is provided on the inner wall of the inspection well base, above the insertion opening. A through hole corresponding to the threaded hole is provided on the plug board, and a bolt is installed in the through hole. In the locked state, the slot of the plug board is aligned with the clamping groove, and the plug board is inserted into the clamping groove from top to bottom. The plug board is fixed to the inner wall of the inspection well base by the bolt installed in the threaded hole. The radial movement of the bolt is limited by the plug board, and the bolt can prevent the plug board from falling off, ensuring the reliability of the locking assembly.

[0008] In this embodiment, the anchoring plate includes a framework, an arc-shaped support plate, and a cross plate. The framework is arranged radially along the inspection well base. One end of the framework is provided with the bolt. Arc-shaped support plates are symmetrically fixed on both sides of the connection between the bolt and the framework. The arc-shaped support plate matches the outer circumferential radian of the inspection well base. Multiple groups of cross plates are arranged along the length direction on both sides of the other end of the framework. The cross plates are arranged horizontally and perpendicular to the framework. The cross plates can increase the contact area between the anchoring plate and the foundation, thereby further increasing the anti-settlement ability of the inspection well. After the bolt is inserted into the insertion opening, the arc-shaped support plate contacts the outer wall of the inspection well base, which can increase the contact area between the anchoring plate and the inspection well base. Cooperating with the plug board, the stability of the connection between the anchoring plate and the inspection well base is improved, while the pressure on the inspection well base is reduced, and the overall service life of the inspection well is prolonged.

[0009] In this embodiment, the inspection well base is coaxially spliced by multiple splicing units. An insertion opening is provided on the outside of each splicing unit. A first socket is provided at the bottom end of the splicing unit, and a socket head matching the first socket is provided at the top end. During installation, the first socket at the lower side of the splicing unit located on the upper side is sleeved on the upper side of the socket head at the upper side of the splicing unit located on the lower side. Multiple splicing units can conveniently adjust the overall depth of the inspection well. When external forces such as local foundation settlement or load act, stress concentration will occur. Multiple splicing units can relieve the stress of the inspection well, avoid the settlement of the entire inspection well due to local settlement, and maintain the stability of the inspection well. The socket head and the first socket can ensure the airtightness of the entire inspection well.

[0010] In this embodiment, a manhole cover support frame is installed on the top of the inspection well base. The manhole cover support frame matches the inner and outer diameters of the splicing unit. A second socket matching the socket head is provided at the bottom end of the manhole cover support frame. The manhole cover support frame is connected through the cooperation of the second socket and the socket head. The second socket can ensure the airtightness between the manhole cover support frame and the inspection well when the leveling assembly adjusts the movement of the manhole cover support frame.

[0011] In this embodiment, a leveling component is further installed inside the manhole cover support frame. The leveling component includes sleeves evenly arranged along the center of the manhole cover support frame and adjusting rods threadedly connected to the sleeves. The sleeves are fixed to the inner wall of the manhole cover support frame in the vertical direction, and the adjusting rods are threadedly connected to the bottom of the sleeves. A support plate is fixed to the bottom of the adjusting rods. On the splicing unit at the top of the inspection well base, a horizontally arranged annular top plate that cooperates with the leveling component is installed on the inner side wall of its socket. The bottom of the manhole cover support frame is supported on the annular top plate through the leveling component. By rotating the adjusting rods, the overall angle and height of the manhole cover support frame can be adjusted to ensure that the manhole cover support frame is flush with the road surface, thereby avoiding the impact of subsequent unevenness between the manhole cover and the ground on the overall inspection well and the surrounding road structure, improving driving comfort and extending the overall service life of the inspection well.

[0012] In summary, the device has the characteristics of high stability, easy installation and disassembly, and strong anti-settlement ability. At the same time, its detachable feature facilitates transportation and assembly, reduces the settlement phenomenon at the joint of the manhole cover, improves driving comfort, and extends the service life of the road.

[0021] As Figures 1-5 shown, a settlement prevention structure for a precast inspection well includes a well base 1 of the inspection well. A plurality of insertion openings 2 are symmetrically arranged at the center of the outer side of the well base 1 of the inspection well. An anchor plate is installed in each insertion opening 2 on the outer side of the well base 1 of the inspection well.

[0022] The anchor plate is arranged radially along the well base 1 of the inspection well. One end of the anchor plate 3 is provided with a plug pin that matches the size of the insertion opening 2. A locking assembly for locking the plug pin is installed in the well base 1 of the inspection well. After the plug pin of the anchor plate 3 is inserted into the insertion opening 2, the plug pin is locked with the well base 1 of the inspection well through the locking assembly, so that the anchor plate 3 is detachably fixed to the well base 1 of the inspection well.

[0023] Further, after the anchor plate 3 is inserted into the insertion opening 2, the end of the plug pin extending into the well base 1 of the inspection well is the locking end. A card slot 4 is formed on the locking end of the plug pin along the circumferential direction of the plug pin. The locking assembly includes a plug plate 9 larger than the insertion opening 2. The plug plate 9 is provided with a slot that matches the cross-sectional size of the position where the card slot is located on the plug pin. A threaded hole 11 is provided on the inner wall of the well base 1 of the inspection well above the insertion opening 2. The plug plate 9 is provided with a through hole corresponding to the threaded hole 11. A bolt 10 is installed in the through hole. In the locked state, the slot of the plug plate 9 is aligned with the card slot 4, the plug plate 9 is inserted into the card slot from top to bottom, and then the bolt 10 on the plug plate 9 is tightened into the threaded hole 11. The radial movement of the plug pin is limited by the plug plate 9, and the bolt 10 can prevent the plug plate 9 from falling off, ensuring the reliability of the locking assembly.

[0024] The anchor plate 3 includes a framework, an arc-shaped support plate 8 and a transverse plate 16. The framework is arranged radially along the inspection well base 1. The plug is provided at one end of the framework. Arc-shaped support plates 8 are symmetrically fixed on both sides of the framework at the connection between the plug and the framework. The arc-shaped support plate 8 matches the outer circumferential radian of the inspection well base 1. Multiple groups of transverse plates 16 are arranged along the length direction on both sides of the other end of the framework. The transverse plates 16 are arranged horizontally and perpendicular to the framework. The transverse plates 16 can increase the contact area between the anchor plate 3 and the foundation, thereby further increasing the anti-settlement ability of the inspection well. After the plug is inserted into the insertion interface 2, the arc-shaped support plate 8 contacts the outer wall of the inspection well base 1, which can increase the contact area between the anchor plate 3 and the inspection well base 1. Cooperating with the insertion plate 9, it improves the connection stability between the anchor plate 3 and the inspection well base 1, and at the same time reduces the pressure on the inspection well base 1 and extends the overall service life of the inspection well.

[0025] When the utility model is installed, the anchor plate 3 is inserted inside the insertion interface 2 and fixed by the insertion plate 9. Multiple anchor plates 3 outside the inspection well base 1 increase the contact area between the inspection well base 1 and the foundation, and make the force in the vertical direction more balanced, thereby preventing the inspection well from settling. When transporting, the inspection well base 1 and the anchor plate 3 can be disassembled for convenient transportation.

[0026] Further, the inspection well base 1 is coaxially spliced by multiple splicing units. An insertion interface 3 is provided on the outside of each splicing unit. A first socket 7 is provided at the bottom end of the splicing unit, and a socket joint 6 matching the first socket 7 is provided at the top end. When installing, the first socket 7 at the lower side of the splicing unit located on the upper side is sleeved on the upper side of the socket joint 6 at the upper side of the splicing unit located on the lower side. Multiple splicing units can conveniently adjust the overall depth of the inspection well. And when external forces such as local foundation settlement or load action occur, stress concentration will be generated. Multiple splicing units can relieve the stress of the inspection well, avoid the settlement of the entire inspection well caused by local settlement, and maintain the stability of the inspection well. The socket joint 6 and the first socket 7 can ensure the airtightness of the whole inspection well.

[0027] A manhole cover support frame 5 is installed on the top of the inspection well base 1. The manhole cover support frame 5 matches the inner and outer diameters of the splicing unit. A second socket 12 matching the socket joint 6 is provided at the bottom end of the manhole cover support frame 5. The manhole cover support frame 5 is connected through the cooperation of the second socket 12 and the socket joint 6. The second socket 12 can ensure the airtightness between the manhole cover support frame 5 and the inspection well when the leveling component adjusts the movement of the manhole cover support frame 5.

[0028] A leveling component is also installed inside the manhole cover support frame 5. The leveling component includes sleeves 13 evenly arranged along the center of the manhole cover support frame 5 and adjusting rods 14 threadedly connected to the sleeves 13. The sleeves 13 are fixed on the inner wall of the manhole cover support frame 5 in the vertical direction, and the adjusting rods 14 are threadedly connected to the bottoms of the sleeves 13. A support plate is fixed to the bottom of the adjusting rod 14. On the splicing unit at the top of the inspection well base 1, a horizontally arranged annular top plate 15 that cooperates with the leveling component is installed on the inner side wall of its receiving joint 6. By rotating the adjusting rod 14, the overall angle and height of the manhole cover support frame 5 can be adjusted to ensure that the manhole cover support frame 5 is flush with the road surface, thereby avoiding the impact of subsequent unevenness between the manhole cover and the ground on the overall inspection well and the surrounding road structure, improving driving comfort and extending the overall service life of the inspection well.
