Description

Technical Field

[0001] The present application relates to the field of inspection wells, and in particular to an assembled inspection well and a construction method thereof. Background Art

[0002] Inspection wells are designed for easy maintenance of urban underground infrastructure, including power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and streetlight lines. They are typically located at pipeline intersections, bends, changes in pipe diameter or slope, and at regular intervals along straight pipe sections to facilitate regular inspection of ancillary structures.

[0003] A Chinese patent application with the authorization publication number CN109989427A discloses a road inspection well, comprising a shaft, a manhole cover mounted on the shaft, the shaft connected to a drainage pipe, and a protective mechanism disposed in the middle of the shaft. The protective mechanism comprises a protective net disposed within the shaft, and a plurality of connectors disposed between the protective net and the shaft for supporting the protective net, with the protective net and connectors being detachably connected. This solution employs a protective net within the shaft, so that if the manhole cover becomes damaged or cracked due to aging, pedestrians who accidentally fall into the shaft will fall onto the protective net, preventing them from falling completely to the bottom of the shaft.

[0004] In the process of realizing this application, the inventors found that there are at least the following problems in this technology: although the inspection well has improved the safety performance, pedestrians and vehicles will constantly run over the well cover on the road, and each time they run over it, pressure is applied to the well shaft. As time goes by, the well shaft will sink. Once the well shaft sinks, the drainage pipe is connected to the well shaft and does not sink with the well shaft. Therefore, the drainage pipe is prone to breakage, so it needs to be improved. Summary of the Invention

[0005] In order to improve the problem that once the wellbore sinks, the drainage pipe is easily broken because the drainage pipe is connected to the wellbore and does not sink with the wellbore, the present application provides an assembled inspection well and a construction method thereof.

[0006] In the first aspect, the present application provides an assembled inspection well adopting the following technical solution:

[0007] An assembled inspection well comprises a well seat, a well shaft and a well cover, the well seat is buried underground, the well shaft is fixed to the top of the well seat, the well cover is arranged on the top of the well shaft, a drainage pipe is arranged in communication with the well seat, a connecting hole is provided through the well seat, an upper hole and a lower hole are provided on the inner wall of the connecting hole, an upper plate is inserted and slidably arranged in the upper hole, a lower plate is inserted and slidably arranged in the lower hole, the lower plate and the upper plate are spliced ​​and connected, and a clearance hole is provided through the spliced ​​connection, the drainage pipe is arranged in the clearance hole, and a sealing component for preventing water in the well seat from leaking is provided between the inner wall of the connecting hole and the drainage pipe.

[0008] By adopting the above technical solution, when the well seat sinks, since the drainage pipe remains stationary and there is space between the upper plate and the bottom of the upper hole, the upper plate and the lower plate both slide upward in the vertical direction. Therefore, even if the well seat sinks, it will not cause the drainage pipe to sink, and the drainage pipe is not likely to break. The function of the sealing component is that when the drainage pipe is draining, the well seat will be filled with water. At this time, through the sealing component, the water in the well seat is not likely to leak out of the well seat, so that the soil around the well seat is not likely to collapse due to excessive water seepage.

[0009] Optionally, the sealing assembly includes a water retaining belt, a sealing sleeve, a fixing block and a fixing bolt. A fixing hole is opened on the inner wall of the connecting hole. The sealing sleeve is mounted on the fixing block. The water retaining belt is fixedly connected to the sealing sleeve. The water retaining belt is inserted into the connecting hole and the drain pipe passes through the water retaining belt and is fixedly connected to the water retaining belt. The fixing block is inserted into the fixing hole and the sealing sleeve is tightly attached to the inner wall of the fixing hole. The fixing block is fixed to the well seat by the fixing bolt.

[0010] By adopting the above technical solution, the well seat will be filled with water. At this time, the water in the well seat is not easy to leak out of the well seat through the water retaining belt, so that the soil around the well seat is not easy to collapse due to excessive water seepage.

[0011] Optionally, a prompt mechanism is provided between the upper plate and the shaft, and the prompt mechanism includes a trigger component and a prompt component. The trigger component is provided between the upper plate and the shaft, and the prompt component is provided on the shaft cover and connected to the trigger component.

[0012] By adopting the above technical solution, when the upper plate slides upward in the vertical direction until it contacts the bottom of the upper hole, the trigger component will operate. The operation of the trigger component will drive the prompt component on the manhole cover to rise, thereby reminding the staff that the manhole seat at this location can no longer be lowered and needs timely maintenance, and reminding pedestrians and vehicles on the road so that pedestrians and vehicles are not likely to run over the manhole cover at this location.

[0013] The top of the wellbore is provided with a trigger cavity and is communicated with the sliding hole. The inner wall of the trigger cavity is provided with a driving hole, one end of the driving rod is rotatably connected to the driving hole, and the other end is coaxially fixed with the driving gear, one end of the screw is rotatably connected to the inner wall of the trigger cavity and coaxially fixed with the driven gear, and the other end is connected to the prompt assembly, the driving gear is meshed with the driven gear, the swing rod is rotatably connected with the inner wall of the trigger cavity, a locking hole is provided on the driving rod, one end of the locking rod is connected to the swing rod, and the other end is inserted into the locking hole, and the balance spring is connected between the swing rod and the inner wall of the trigger cavity.

[0014] By adopting the above technical solution, when the upper plate slides upward in the vertical direction until it contacts the bottom of the upper hole, the trigger rod will lift the end of the swing rod located in the sliding hole, and the end of the swing rod away from the trigger rod will descend to drive the card rod to move out of the card hole. Then, since the coil spring was previously in a stored force state, the coil spring will be released to drive the drive rod to rotate. The rotation of the drive rod will drive the rotation of the driving gear, the driven gear and the screw in turn. The rotation of the screw will drive the reminder assembly on the manhole cover to rise.

[0015] Optionally, the prompt component includes a slider, a push rod, a support plate and a prompt cone, the slider is inserted and slides in the trigger chamber, the screw passes through the slider and is threadedly connected to the slider, a receiving hole is provided on the top of the manhole cover, the support plate is inserted and slides in the receiving hole, the prompt cone is fixed on the support plate and is located in the receiving hole, one end of the push rod is connected to the slider, and a through hole is provided at the bottom of the receiving hole. When the trigger assembly is operating, the end of the push rod away from the slider passes through the through hole and extends into the receiving hole to abut against the support plate.

[0016] By adopting the above technical solution, when the screw rotates, the rotation of the screw will drive the slider to slide upward in the vertical direction. At this time, the push rod will penetrate the penetration hole and extend into the accommodating hole to abut against the bottom wall of the supporting plate, and then lift the supporting plate upward in the vertical direction until the prompt cone extends out of the accommodating hole.

[0017] Optionally, a light-emitting component is provided between the manhole cover and the prompt cone, and the light-emitting component includes a solar panel, a grid plate, a light-emitting lamp, a battery, a light-emitting switch and a limit plate. A placement hole is provided on the top of the manhole cover, and the solar panel and the battery are both fixed in the placement hole. The solar panel charges the battery when exposed to light. The grid plate cover is provided at the opening of the placement hole. The light-emitting lamp is fixed on the prompt cone and electrically connected to the battery. A sliding groove is provided on the inner wall of the accommodating hole. The limit plate is inserted and slides in the sliding groove and is fixed to the supporting plate. The light-emitting switch is fixed on the limit plate and electrically connected to the light-emitting lamp.

[0018] By adopting the above technical solution, when the warning cone extends out of the accommodating hole, the light switch on the limit plate will abut against the inner wall of the slide groove and the light switch will be pressed and maintained in this state. At this time, the light will light up and remain in the bright state, thereby further warning pedestrians and vehicles on the road so that pedestrians and vehicles are not likely to run over the manhole cover at that location; and by converting solar energy into electrical energy for use, energy-saving effects can be achieved.

[0019] Optionally, a lighting assembly is provided in the well shaft, and the lighting assembly includes an LED light strip and a lighting switch.

The LED light strip is electrically connected to the lighting switch, and the lighting switch is electrically connected to the battery. A start-stop assembly for controlling the lighting switch is provided between the lighting switch and the well cover.

[0020] By adopting the above technical solution, when the ring block on the manhole cover is screwed into the threaded hole on the wellbore, the start-stop assembly will be separated from the lighting switch and the LED light strip will be kept off; once the well seat needs to be cleaned or repaired, the manhole cover is separated from the wellbore, and the start-stop assembly will automatically press the lighting switch to make the LED light strip light up and maintain this state, so that the staff can see the specific situation inside the well seat clearly and carry out cleaning or maintenance.

[0021] Optionally, the start-break assembly includes a push rod, a start-break spring and a rotating rod, the rotating rod is rotatably connected to the inner wall of the accommodating chamber, a threaded hole is provided on the top wall of the wellbore, and a ring block is fixedly provided on the bottom wall of the manhole cover, the ring block is threadedly connected to the threaded hole, and a push hole is provided on the inner wall of the threaded hole, one end of the push rod is inserted into the push hole and abuts against the ring block, the other end passes through the accommodating chamber and is hinged to the rotating rod, the start-break spring is sleeved on the push rod and one end is fixed to the bottom of the push hole, and the other end is fixed to the push rod, and a guide surface is provided at one end of the push rod located in the push hole.

[0022] By adopting the above technical solution, when the ring block on the manhole cover is screwed into the threaded hole on the wellbore, the ring block on the manhole cover will contact the guide surface on the push rod. At this time, the push rod will move into the accommodating cavity through the guide surface and the starting and breaking spring will be compressed. The movement of the push rod will drive the rotating rod to rotate to separate the bottom end of the rotating rod from the lighting switch to achieve the effect of turning off the LED light strip; when the ring block on the manhole cover is unscrewed from the threaded hole on the wellbore, the unscrewing of the ring block on the manhole cover will make space for the push rod, and the push rod will move into the threaded hole on the wellbore through the elastic force of the starting and breaking spring. At this time, the push rod will drive the rotating rod to rotate to make the bottom end of the rotating rod contact with the lighting switch and press the lighting switch to achieve the effect of turning on the LED light strip.

[0023] Optionally, a reinforcement assembly is provided on the well seat, and the reinforcement assembly includes an anchor rod, a screw rod and a grouting pipe.

[0024] By adopting the above technical solution, after the well seat is buried underground, the staff enters the well seat, passes their hand through the first hole and reaches into the reinforced hole to hold the screw rod, and then rotates the screw rod to drive the anchor rod to be inserted into the soil layer, thereby improving the stability of the well seat when buried underground, so that the well seat is not prone to rapid settlement in a short period of time.

[0025] In a second aspect, the present application provides a construction method for an assembled inspection well, which adopts the following technical solution:

[0026] A construction method for an assembled inspection well comprises the following steps:

[0031] S5. The worker puts his hand through the first hole and reaches into the reinforcement hole to hold the screw and rotate it. At this time, the anchor rod does not rotate but is inserted into the soil layer to enhance the stability of the well seat.

[0032] S6. Screw the grouting pipe into the first hole, and the ground personnel inject concrete slurry into the grouting pipe. At this time, the concrete slurry will be poured into the reinforcement hole, and then poured into the soil layer where the anchor rod is inserted through the grouting hole on the anchor rod.

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-7 This application is described in further detail.

[0048] The embodiment of the present application discloses an assembled inspection well. Figure 1 and Figure 2 An assembled inspection well includes a well base 1, a well shaft 2, and a well cover 3, and the well base 1, well shaft 2, and well cover 3 are all cylindrical. The top walls of the well base 1 and the well shaft 2 are both provided with an annular threaded hole 11, and the bottom walls of the well cover 3 and the well shaft 2 are both fixedly provided with an annular ring block 21, which is threadedly connected to the threaded hole 11, thereby completing the connection between the well base 1, the well shaft 2, and the well cover 3; and in the embodiment of the present application, the thread direction of the ring block 21 on the well cover 3 is opposite to that of the ring block 21 on the well shaft 2, so that when disassembling, it is only necessary to rotate the well cover 3 to separate the well cover 3 from the well shaft 2; and it is possible to separate the well shaft 2 from the well base 1 by rotating the well shaft 2.

[0049] Reference Figure 1 and Figure 2 A pair of drain pipes 192 are connected to the well seat 1, and the two drain pipes 192 are arranged opposite each other. A filter screen 35 is fixedly installed on the bottom wall of the well cover 3, and the filter screen 35 is inserted into the well shaft 2. The function of the filter screen 35 is to filter out some impurities when rainwater enters the well seat 1 through the well cover 3 on rainy days, thereby making the drain pipes 192 less likely to be blocked during drainage.

[0050] Reference Figure 1 and Figure 2 Two communication holes 12 are formed through the side wall of the well seat 1, and the two communication holes 12 correspond one-to-one to the two drainage pipes 192. An upper hole 13 is formed on the inner top wall of the communication hole 12, and a lower hole 14 is formed on the inner bottom wall. The depth of the upper hole 13 is greater than the depth of the lower hole 14. An upper plate 16 is inserted into the upper hole 13 and can slide in the vertical direction. A space is left between the upper plate 16 and the bottom of the upper hole 13. A lower plate 17 is inserted into the lower hole 14 and can slide in the vertical direction. The lower plate 17 contacts the bottom of the lower hole 14. The upper plate 16 and the lower plate 17 are spliced ​​and connected and are integrally formed.

[0051] Reference Figure 2 A clearance hole 18 is provided at the joint of the upper plate 16 and the lower plate 17, and a drainage pipe 192 is provided through the clearance hole 18. Since pedestrians and vehicles will constantly pass over the manhole cover 3 on the road, pressure is applied to the manhole 2 every time they pass over it. And as time goes by, when the manhole seat 1 is about to sink, since the drainage pipe 192 remains stationary and there is space between the upper plate 16 and the bottom of the upper hole 13, the upper plate 16 and the lower plate 17 both slide upward in the vertical direction. Therefore, even if the manhole seat 1 sinks, it will not cause the drainage pipe 192 to sink, and the drainage pipe 192 is not easy to break.

[0052] Reference Figure 1 A sealing component 4 is provided between the inner wall of the communicating hole 12 and the drain pipe 192. The function of the sealing component 4 is that when the drain pipe 192 is draining, the well seat 1 will be filled with water. At this time, through the sealing component 4, the water in the well seat 1 is not easy to leak out of the well seat 1, so that the soil around the well seat 1 is not easy to collapse due to excessive water seepage.

[0053] Reference Figure 2The sealing assembly 4 includes a water retaining strip 41, a sealing sleeve 42, a fixing block 43, and a fixing bolt 44. The water retaining strip 41 is adapted to be inserted into the communication hole 12. In the embodiment of the present application, the water retaining strip 41 is made of a flexible rubber material so that the water retaining strip 41 can be stretched or folded. The drain pipe 192 passes through the water retaining strip 41 and is fixedly connected to the water retaining strip 41. The circumferential inner wall of the communication hole 12 is provided with fixing holes 15. The sealing sleeve 42 is fixedly sleeved on the fixing block 43. In the embodiment of the present application, there are four sealing sleeves 42, and the four sealing sleeves 42 correspond one-to-one to the four sides of the water retaining strip 41. The sealing sleeves 42 are fixedly connected to the water retaining strip 41.

[0054] Reference Figure 2 The fixing block 43 is inserted into the fixing hole 15, and the sealing sleeve 42 is tightly attached to the inner wall of the fixing hole 15. The sealing sleeve 42 is used to prevent water in the well seat 1 from leaking out of the well seat 1. The fixing block 43 is fixed to the well seat 1 by fixing bolts 44. On the one hand, this improves the stability of the water retaining belt 41, and on the other hand, it is easy to remove and replace the water retaining belt 41 if it is damaged.

[0055] Reference Figure 1 and Figure 2 A prompt mechanism is provided between the upper plate 16 and the shaft 2. The prompt mechanism includes a trigger assembly 5 and a prompt assembly 6. The trigger assembly 5 is provided between the upper plate 16 and the shaft 2, and the prompt assembly 6 is provided on the manhole cover 3 and connected to the trigger assembly 5. When the upper plate 16 slides upward in the vertical direction until it contacts the bottom of the upper hole 13, the trigger assembly 5 will be activated. The operation of the trigger assembly 5 will drive the prompt assembly 6 on the manhole cover 3 to rise, thereby notifying the staff that the manhole seat 1 at this location can no longer be lowered and needs to be repaired in time, and also notifying pedestrians and vehicles on the road so that pedestrians and vehicles are less likely to run over the manhole cover 3 at this location.

[0056] Reference Figure 2 and Figure 3 The trigger assembly 5 includes a trigger rod 51, a coil spring 52, a drive rod 53, a swing rod 54, a balance spring 55, a latch rod 56, a driving gear 57, a driven gear 58, and a screw 59. A sliding hole 23 is provided on the bottom wall of the wellbore 2. One end of the trigger rod 51 is inserted into the sliding hole 23 and can slide vertically, while the other end passes through the upper hole 13 and abuts against the top wall of the upper plate 16. In the embodiment of the present application, when the wellbore 2 is connected to the well seat 1, the trigger rod 51 is unlikely to fall into the upper hole 13 during the rotation of the wellbore 2. To prevent the trigger rod 51 from falling into the upper hole 13, a staff member can be arranged in the well seat 1 to hold the trigger rod 51 so that the trigger rod 51 does not fall into the upper hole 13. After the wellbore 2 is completed, the trigger rod 51 will automatically fall into the upper hole 13 due to its own weight.

[0057] Reference Figure 3A trigger chamber 22 is provided at the top of the shaft 2 and extends vertically downward, communicating with the slide hole 23. The trigger chamber 22 is L-shaped, with one end of a screw rod 59 rotatably connected to the inner bottom wall of the trigger chamber 22 and coaxially fixed to the driven gear 58, while the other end is connected to the prompt assembly 6. A drive hole 26 is provided on the inner wall of the trigger chamber 22. One end of a drive rod 53 is inserted into the drive hole 26 and rotatably connected to the bottom of the drive hole 26, while the other end is coaxially fixed to the driving gear 57. The drive rod 53 is arranged horizontally, and the driving gear 57 meshes with the driven gear 58. A coil spring 52 is sleeved on one end of the drive rod 53 located in the drive hole 26, with one end of the coil spring 52 fixed to the inner wall of the drive hole 26 and the other end fixed to the drive rod 53. In the embodiment of the present application, the initial state of the coil spring 52 is a stored force state.

[0058] Reference Figure 3 The swing lever 54 is rotatably connected to the inner wall of the trigger chamber 22 and is located below the drive lever 53. A latching hole 27 is defined in the side wall of the drive lever 53, distal to the coil spring 52. A latching rod 56 has one end fixedly connected to one end of the swing lever 54 and the other end inserted into the latching hole 27. The latching rod 56 can be rotated out of the latching hole 27. A balancing spring 55 is fixedly connected between the end of the swing lever 54 distal to the latching rod 56 and the inner bottom wall of the trigger chamber 22. The end of the swing lever 54 distal to the latching rod 56 extends into the slide hole 23. The balancing spring 55 maintains the swing lever 54 in a horizontal position, ensuring that the latching rod 56 is stably inserted into the latching hole 27.

[0059] Reference Figure 3 When the upper plate 16 slides upward in the vertical direction until it contacts the bottom of the upper hole 13, the trigger rod 51 lifts the end of the swing rod 54 located in the sliding hole 23, and the end of the swing rod 54 away from the trigger rod 51 will drop to drive the clamping rod 56 to move out of the clamping hole 27. Then, since the coil spring 52 was previously in a charged state, the coil spring 52 will be released at this time to drive the driving rod 53 to rotate. The rotation of the driving rod 53 will sequentially drive the rotation of the driving gear 57, the driven gear 58 and the screw 59. The rotation of the screw 59 will drive the prompt assembly 6 on the manhole cover 3 to rise, thereby reminding the staff that the manhole seat 1 at this location can no longer be lowered and needs timely maintenance, and reminding pedestrians and vehicles on the road so that pedestrians and vehicles are not likely to run over the manhole cover 3 at this location.

[0060] Reference Figure 1 and Figure 4The prompt component 6 includes a slider 61, a push rod 62, a supporting plate 63 and a prompt cone 64. The slider 61 is adapted to be inserted into the trigger chamber 22 and can slide in the vertical direction. The end of the screw 59 away from the driven gear 58 passes through the slider 61 and is threadedly connected to the slider 61. The top wall of the manhole cover 3 is provided with a receiving hole 31. The supporting plate 63 is adapted to be inserted into the receiving hole 31 and can slide in the vertical direction. The bottom of the receiving hole 31 is provided with a through-hole 34 for the push rod 62 to pass through. In the embodiment of the present application, there are two push rods 62, and the two push rods 62 are fixed to the top of the slider 61 and are symmetrically arranged with the screw 59 as the center. In the embodiment of the present application, the opening area of ​​the receiving hole 31 is not large enough for pedestrians to step in or for the tires of vehicles to press in.

[0061] Reference Figure 4 The prompt cone 64 is fixed to the top wall of the supporting plate 63, and its initial state is that it is completely received in the accommodating hole 31. When the screw 59 is rotated, the rotation of the screw 59 will drive the slider 61 to slide upward in the vertical direction. At this time, the push rod 62 will penetrate the penetration hole 34 and extend into the accommodating hole 31 to abut against the bottom wall of the supporting plate 63, and then the supporting plate 63 will be lifted upward in the vertical direction until the prompt cone 64 extends out of the accommodating hole 31, thereby reminding the staff that the manhole seat 1 at this location can no longer be lowered and needs timely maintenance, and reminding pedestrians and vehicles on the road so that pedestrians and vehicles are not likely to run over the manhole cover 3 at this location.

[0062] Reference Figure 4 and Figure 5 A light-emitting assembly 7 is disposed between the manhole cover 3 and the warning cone 64. The light-emitting assembly 7 includes a solar panel 71, a grid plate 72, a light 73, a battery 74, a light switch 75, and a limit plate 76. A hole 33 is located at the center of the top wall of the manhole cover 3. The solar panel 71 is secured within the hole 33, and the battery 74 is secured to the bottom of the hole 33. When exposed to light, the solar panel 71 charges the battery 74. The grid plate 72 is welded to the opening of the hole 33. The grid plate 72 serves to prevent the solar panel 71 from receiving light and to prevent it from being crushed by pedestrians or vehicles.

[0063] Reference Figure 4 and Figure 5The light-emitting lamp 73 is fixed on the warning cone 64 and electrically connected to the battery 74. In the embodiment of the present application, there are four light-emitting lamps 73. The inner wall of the accommodating hole 31 is provided with a slide groove 32. The limiting plate 76 is inserted into the slide groove 32 and can slide in the vertical direction. The limiting plate 76 is fixedly connected to the supporting plate 63. The light-emitting switch 75 is fixed to the top wall of the limiting plate 76 and electrically connected to the light-emitting lamp 73. When the warning cone 64 extends out of the accommodating hole 31, the light-emitting switch 75 on the limiting plate 76 will abut against the inner top wall of the slide groove 32, pressing the light-emitting switch 75 and maintaining this state. At this time, the light-emitting lamp 73 will light up and remain in the light-emitting state, thereby further warning pedestrians and vehicles on the road so that pedestrians and vehicles are less likely to run over the manhole cover 3 at this location; and by converting solar energy into electrical energy for use, it can achieve an energy-saving effect.

[0064] Reference Figure 5 In addition, the battery 74 and the light 73 are covered with a transparent protective cover 731, and the protective cover 731 on the battery 74 is fixedly connected to the bottom of the placement hole 33, and the protective cover 731 on the light 73 is fixedly connected to the prompt cone 64. The function of the protective cover 731 is to prevent the battery 74 and the light 73 from being damaged by rain on rainy days.

[0065] Reference Figure 1 and Figure 6 A lighting assembly 8 is installed within the shaft 2. The lighting assembly 8 includes an LED light strip 81 and a lighting switch 82. The LED light strip 81 is fixed to the inner wall of the shaft 2 and spirally arranged in a vertical direction and electrically connected to the battery 74. The LED light strip 81 is also covered with a protective cover 731, which is fixedly connected to the inner wall of the shaft 2. A receiving chamber 24 is defined within the shaft 2 on a side away from the trigger chamber 22. The lighting switch 82 is fixed within the receiving chamber 24 and electrically connected to the LED light strip 81. A trip assembly 9 is provided between the lighting switch 82 and the ring block 21 on the shaft cover 3.

[0066] Reference Figure 6 When the ring block 21 on the manhole cover 3 is screwed into the threaded hole 11 on the wellbore 2, the starting and breaking assembly 9 will be separated from the lighting switch 82 and the LED light strip 81 will be kept off; once the well seat 1 needs to be cleaned or repaired, the manhole cover 3 is separated from the wellbore 2. At this time, the starting and breaking assembly 9 will automatically press the lighting switch 82 to make the LED light strip 81 light up and maintain this state, so that the staff can see the specific situation inside the well seat 1 clearly, so that the staff can carry out cleaning or maintenance.

[0067] Reference Figure 6The trip assembly 9 includes a push rod 91, a trip spring 92, and a rotating rod 93. The rotating rod 93 is rotatably connected to the inner wall of the accommodating chamber 24. A push hole 25 is formed in the inner wall of the threaded hole 11 on the shaft 2. One end of the push rod 91 is inserted into the push hole 25 and abuts against the ring block 21 on the manhole cover 3. The other end extends into the accommodating chamber 24 and is hinged to the top of the rotating rod 93. The bottom end of the rotating rod 93 is separated from the lighting switch 82. A guide surface 911 is provided on the top wall of the push rod 91 at one end located in the push hole 25. When the ring block 21 is screwed out of the threaded hole 11, the push rod 91 extends into the threaded hole 11. At this time, the end of the guide surface 911 near the accommodating chamber 24 is lower than the opening of the push hole 25.

[0068] Reference Figure 6 The trip spring 92 is sleeved on one end of the push rod 91 located in the push hole 25, with one end fixedly connected to the bottom of the push hole 25 and the other end fixedly connected to the side wall of the push rod 91. When the push rod 91 abuts the ring block 21 on the manhole cover 3, the trip spring 92 is in a compressed state. In the embodiment of the present application, the threaded hole 11 on the shaft 2 has a thread distance from the top of the push hole 25 opening to the opening of the threaded hole 11, so that when the ring block 21 on the shaft 3 is screwed out of the threaded hole 11 on the shaft 2, the push rod 91 will affect the ring block 21 on the shaft 2.

[0069] Reference Figure 6 When the ring block 21 on the manhole cover 3 is screwed into the threaded hole 11 on the well shaft 2, the ring block 21 on the manhole cover 3 will contact the guide surface 911 on the push rod 91. At this time, the push rod 91 will move into the accommodating cavity 24 through the guide surface 911 and the trip spring 92 will be compressed. The movement of the push rod 91 will drive the rotating rod 93 to rotate so that the bottom end of the rotating rod 93 is separated from the lighting switch 82, thereby turning off the LED light strip 81; when the ring block 21 on the manhole cover 3 is unscrewed from the threaded hole 11 on the well shaft 2, the unscrewing of the ring block 21 on the manhole cover 3 will make space for the push rod 91, and the push rod 91 will move into the threaded hole 11 on the well shaft 2 by the elastic force of the trip spring 92. At this time, the push rod 91 will drive the rotating rod 93 to rotate so that the bottom end of the rotating rod 93 contacts the lighting switch 82 and presses the lighting switch 82 to turn on the LED light strip 81.

[0070] Reference Figure 1 and Figure 7 A reinforcement assembly 10 is provided at the bottom of the well seat 1, and the reinforcement assembly 10 includes an anchor rod 101, a screw rod 102 and a slurry guide pipe 103. A reinforcement hole 19 is opened on the outer wall of the well seat 1 and below the drainage pipe 192. One end of the anchor rod 101 is inserted into the reinforcement hole 19 and the other end is inserted into the soil layer. When the well seat 1 is not buried underground, the anchor rod 101 is completely received in the reinforcement hole 19. In the embodiment of the present application, the anchor rod 101 is set to be square and the end away from the reinforcement hole 19 is a pointed end.

[0071] Reference Figure 7 A connecting hole 1012 is formed on the end wall of one end of the anchor rod 101 located in the reinforcement hole 19. The screw rod 102 is rotatably connected to the inner wall of the reinforcement hole 19 and is arranged horizontally. The end of the screw rod 102 near the anchor rod 101 is threadedly connected to the connecting hole 1012. A first hole 191 is formed at the center of the inner bottom wall of the well seat 1 and is connected to the reinforcement hole 19. After the well seat 1 is buried underground, a worker enters the well seat 1, passes his hand through the first hole 191 and reaches into the reinforcement hole 19 to grasp the screw rod 102, and then rotates the screw rod 102 to drive the anchor rod 101 into the soil layer, thereby improving the stability of the well seat 1 when buried underground and preventing the well seat 1 from rapidly settling in a short period of time.

[0072] Reference Figure 7 The grouting pipe 103 is threadedly connected to the first hole 191 and the grouting pipe 103 is connected to the reinforcement hole 19. The side wall of the anchor rod 101 is penetrated with a grouting hole 1011 and the grouting hole 1011 is connected to the reinforcement hole 19. When the well seat 1 is buried underground, the grouting pipe 103 is screwed into the first hole 191, and then the concrete slurry is transported to the reinforcement hole 19 through the grouting pipe 103, and then transported from the reinforcement hole 19 to the grouting hole 1011 on the anchor rod 101, and finally from the grouting hole 1011. 11 is grouting the soil layer into which the anchor rod 101 is inserted; after the concrete slurry solidifies, the stability of the anchor rod 101 after being inserted into the soil layer can be enhanced, thereby indirectly further improving the stability of the well seat 1, so as to further prevent the well seat 1 from rapidly settling in a short period of time; and the function of the grouting pipe 103 is not only to transport the concrete slurry, but also when the staff is lifted from the ground to the well seat 1 by the lifting rope, the staff can support the grouting pipe 103 and slide downward along the grouting pipe 103.

[0073] In the embodiment of the present application, when the well seat 1 cannot sink any further, the staff cannot open the well cover 3 and can repair the sinking of the well seat 1 by breaking the ground from the outside of the well seat 1.

[0074] The implementation principle of an assembled inspection well in an embodiment of the present application is as follows: when the well seat 1 sinks, since the drainage pipe 192 remains stationary and there is space between the upper plate 16 and the bottom of the upper hole 13, the upper plate 16 and the lower plate 17 both slide upward in the vertical direction. Therefore, even if the well seat 1 sinks, it will not cause the drainage pipe 192 to sink, and the drainage pipe 192 is not likely to break.

[0075] The embodiment of the present application also discloses a construction method of an assembled inspection well.

[0076] A construction method for an assembled inspection well comprises the following steps:

[0077] S1. Excavate a foundation pit on the ground and place the well seat 1 in the foundation pit;

[0078] S2, push the drainage pipe 192 into the well seat 1;

[0079] S3, fixing the sealing assembly 4 between the drain pipe 192 and the inner wall of the communication hole 12;

[0080] S4. Screw the ring block 21 on the wellbore 2 into the threaded hole 11 on the well seat 1, thereby completing the connection between the wellbore 2 and the well seat 1;

[0081] S5. The worker puts his hand through the first hole 191 and reaches into the reinforcement hole 19 to hold the screw rod 102 and rotate it. At this time, the anchor rod 101 does not rotate but is inserted into the soil layer to enhance the stability of the well seat 1.

[0082] S6. Screw the grouting pipe 103 into the first hole 191, and the ground personnel inject concrete slurry into the grouting pipe 103. At this time, the concrete slurry will be poured into the reinforcement hole 19, and then poured into the soil layer where the anchor rod 101 is inserted through the grouting hole 1011 on the anchor rod 101. After the concrete slurry solidifies, it can improve the stability of the anchor rod 101 after it is inserted into the soil layer.

[0083] S7. Screw the ring block 21 on the manhole cover 3 into the threaded hole 11 on the wellbore 2, thereby completing the connection between the manhole cover 3 and the wellbore 2, and then completing the installation of the entire inspection well.

[0084] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
