Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal infrastructure, in particular to a method for intelligently repairing a municipal infrastructure inspection well at a fixed point. BACKGROUND

[0002] At present, China is comprehensively promoting the "urban renewal" process. In most old city renewal and reconstruction projects, the municipal infrastructure such as inspection wells has reached or is close to the preset construction period (generally 50 years). Inspection wells are set for the maintenance and installation of urban underground infrastructure such as power supply, water supply, drainage, sewage, communication, cable television, gas pipe, street lamp line, etc. They are generally set at the intersection of pipelines, at the turning point, at the point where the pipe diameter or slope changes, and at regular intervals on straight pipe sections to facilitate regular inspection of the auxiliary structures. The construction materials of inspection wells are generally stone, brick, concrete or reinforced concrete. Most of the inspection wells in China are brick-laid and coated with cement mortar, and a small number of inspection wells are also prefabricated with reinforced concrete. However, brick-laid or reinforced concrete prefabricated inspection wells are easily eroded by the humid environment of underground space after years of use (inspection wells of sewage pipelines are usually coated with anticorrosive paint during construction, but the anticorrosive paint will also fall off under the long-term corrosion of water vapor and sewage gas; inspection wells of rainwater pipelines and other municipal underground infrastructure are usually not coated with anticorrosive paint, and are more easily eroded by underground water vapor), thereby causing damage to the internal structure of the inspection well and causing structural defects such as concrete erosion, reinforcement exposure, well body leakage, deformation and even collapse, which poses a great safety hazard to the operation of the facilities.

[0003] For such dilapidated inspection wells, if they are demolished and rebuilt in the process of urban renewal, it will not only cost a lot and take a long time, but also cause the municipal underground infrastructure to be paralyzed during the reconstruction period. Therefore, there is an urgent need for an engineering technology that can quickly, accurately and non-excavation repair inspection wells, so as to greatly extend the service life of the inspection wells through in-situ repair at a lower cost.

[0004] Patent No. 201220244179.1 and patent No. 201720554794.5 both disclose technical solutions for repairing the target by fully and uniformly spraying paint on the side wall of the inspection well, but do not have technical solutions for targeted repair of the leakage of the inspection well side wall. In today's society with faster pace of urban residents' life and travel, the technical defects of such full and uniform spraying repair technology are increasingly exposed, which cannot accurately detect the leakage of the inspection well and cannot repair at a fixed point, and has defects such as complicated construction, long time-consuming, and waste of paint. SUMMARY

[0005] The technical problem solved by the present application is to provide a method for intelligently repairing a manhole of municipal infrastructure to overcome the defects that the manhole leakage cannot be accurately detected and cannot be repaired at a specific point in the prior art.

[0006] The present application solves the above technical problems by the following technical solutions:

[0008] S1, scanning a wall of the manhole by a probe part of a positioning assembly to obtain a to-be-repaired area on the wall;

[0009] S2, moving the repairing assembly in the manhole along a height direction by a driving assembly to align a nozzle part of the repairing assembly with the to-be-repaired area.

[0010] In the present application, the accurate detection and the specific repair of the manhole leakage are completed by the cooperation of the steps S1, S2 and S3, wherein in the step S1, the inner wall of the manhole is smoothly scanned by the positioning assembly to obtain an image, so as to determine the position of the abnormal to-be-repaired area; in the step S2, the nozzle part is smoothly aligned with the area to be repaired; and in the step S3, the specific repair is realized to overcome the defects of the full and uniform spraying repair of the manhole in the prior art, such as complicated construction, long time consumption and waste of paint, so as to significantly improve the work efficiency and save the materials.

[0011] Preferably, before the step S1, the following step S01 is further included: checking a water level in the manhole to determine whether to drain the stored water in the manhole.

[0012] In the present application, before the scanning and positioning of the abnormal to-be-repaired area in the manhole are performed, the originally stored water in the manhole needs to be drained to facilitate the operation and cooperation of the parts in a suitable environment and improve the accuracy of detection and repair.

Before step S1, step S03 of supplementing raw materials to the spray head component through the curing agent pump cabin is further included.

[0028] S12, the probe component acquires the to-be-repaired area on the well wall and sends the position information of the to-be-repaired area to the power supply controller;

Based on the structural characteristics of the driving assembly 1 and the diverse situations that may exist on site, the positions of the positioning assembly 2 and the repairing assembly connected with the driving assembly 1 need to be adjusted according to the repair requirements of the inspection well 6 at any time, which can increase the adaptability of the device for intelligently repairing the inspection well of municipal infrastructure.

[0111] As shown in Figure 1 and Figure 2As shown, in a preferred embodiment, the positioning component 2 and the repair component 4 can be respectively connected to the two sides of the traction chain 17. As the traction chain 17 rotates, the positioning component 2 and the repair component 4 move in opposite directions. The positioning component 2 and the repair component 4 can be connected to the same side of the traction chain 17. In a further preferred embodiment, the repair component 4 can also be disposed on the positioning component 2, and the two form an integral structure, both of which move with the traction chain 17.

[0112] like Figure 9 As shown, the implementation method also includes the following steps: S5, dismantling the device for intelligent fixed-point repair of municipal infrastructure manholes; S6, removing the airbag 10 installed at the interface between the manhole 6 and the upstream and downstream drainage pipes 8, and releasing the air; S7, cleaning the device for intelligent fixed-point repair of municipal infrastructure manholes. After the installation and operation processes are completed, the device for intelligent fixed-point repair of municipal infrastructure manholes is dismantled sequentially. The advantage of doing so is that, based on the environmental characteristics and construction characteristics around the manholes, the device closest to the ground is dismantled first, and the device closest to the bottom of the manhole is dismantled last, which conforms to the on-site dismantling process and improves the efficiency of dismantling.

[0113] Specifically, such as Figure 7 , Figure 8 and Figure 9 As shown, the method for intelligent fixed-point repair of municipal infrastructure manholes is divided into three stages: installation, operation, and dismantling.

[0114] Specifically, such as Figure 7 As shown, the installation stage can be divided into the following steps: First, pre-install the internal components of the positioning assembly 2, power controller 3, repair assembly 4, and curing agent pump chamber 5. For inspection wells 6 with high water levels 7, airbags 10 must be installed at the interfaces between the inspection well 6 and the upstream and downstream drainage pipes 8, and air must be inflated into the airbags 10 to block the water from the upstream drainage pipes 8, while simultaneously pumping out the accumulated water outside the airbags 10. For inspection wells 6 with low water levels 7, this step can be skipped. Then, connect the support base 11, support rod 12, driven sprocket 16, telescopic rod 14, support top rod 13, and drive sprocket 15 in sequence. Adjust the length of the telescopic rod 14 so that the overall height of the drive assembly 1 exceeds the depth of the inspection well 6 by 0.3-1.5 m. Then, place the drive assembly 1 vertically inside the inspection well. Install the traction chain 17 on the drive sprocket 15 and driven sprocket 16, connect the shaft of the motor 18 to the central shaft of the drive sprocket 15, and then fix the motor bracket 19. S01, S02, and S03 can be selected in any order, depending on the specific construction environment.

[0115] Specifically, such as Figure 8As shown, the operation stage can be divided into the following steps: the connecting hanging ring 21 of the positioning assembly 2 is engaged with the top pin shaft of the traction chain 17 on one side of the driving assembly 1, then the positioning assembly 2 is uniformly moved from the top of the inspection well 6 to the bottom of the inspection well 6 by the control of the power supply controller 3, and the internal structure of the inspection well 6 is scanned and imaged in three dimensions; when the positioning assembly 2 moves to the bottom of the inspection well 6, the connecting hanging ring 21 of the repair assembly is engaged with the top pin shaft of the traction chain 17 on the other side of the driving assembly 1, then the repair assembly 4 is uniformly moved from the top of the inspection well 6 to the bottom of the inspection well 6 by the control of the power supply controller 3, and the solidifying agent is sprayed according to the scanning result of the internal structure of the inspection well 6 by the positioning assembly 2, so as to realize the repair of the inspection well 6; when the repair assembly 4 moves to the bottom of the inspection well 6, the positioning assembly 2 on the other side of the driving assembly 1 just moves to the top of the inspection well 6, the positioning assembly 2 is removed, then the repair assembly 4 is transported from the bottom of the inspection well 6 to the top of the inspection well 6, and the repair assembly 4 is removed; the installation positions of the positioning assembly 2 and the repair assembly 4 on the driving assembly 1 are adjusted, and the above steps are repeated, so as to complete the whole leakage detection and pinpointing repair operation of the inspection well 6.

[0116] Specifically, as shown in Figure 9 the disassembly stage can be divided into the following steps: the connection between the electric motor 18 and the driving sprocket 15 is disassembled, the connection between the motor support 19 and the ground is disassembled, then the traction chain 17 is disassembled from the driving sprocket 15 and the driven sprocket 16; the driving assembly 1 is taken out of the inspection well 6, the length of the telescopic rod 14 is compressed to the shortest, then the support base 11, the support bottom rod 12, the driven sprocket 16, the telescopic rod 14, the support top rod 13 and the driving sprocket 15 are disassembled in sequence; for the inspection well 6 with a high inspection well water level 7, the air in the air bag 10 installed at the interface between the inspection well 6 and the upstream and downstream drainage pipelines 8 is emptied; the internal components of the positioning assembly 2, the power supply controller 3, the repair assembly 4 and the solidifying agent pump cabin 5 are disassembled, cleaned and placed, ready for next use.

[0117] The inspection well repaired by the embodiment is expected to extend the service life by 20-30 years.
