Description

Technical Field

[0001] The utility model relates to the field of municipal construction, in particular to a micro-pipeline dredging and obstacle-clearing device driven by high-pressure hydraulic power. Background Art

[0002] With the rapid development of urban construction in my country, a large number of underground pipelines will inevitably have serious structural problems such as pipeline rupture, leakage, corrosion, etc. after being put into operation for several years due to external forces or their own service life. It is even very easy to damage the drainage pipes during the construction of urban underground structures, and flow into hydraulic materials such as cement slurry or concrete, causing serious blockage of the pipes. After the completion of the construction of some new pipelines, cement slurry infiltration caused by urbanization transformation and foundation grouting reinforcement is also easy to block the pipes. Due to the small diameter of the pipes, manual cleaning is difficult.

[0003] However, the existing pipeline clearing devices have fixed structures, large volumes, and are not suitable for deep-drilling pipelines, which have great limitations. If the pipe diameter is small, the operators cannot enter the pipeline for close-range clearing. If it is located under the existing roadway or in a section that is not suitable for excavation, excavation and replacement of the pipeline will cause traffic congestion and damage to other pipelines, causing great adverse social effects and increasing the cost.

[0004] According to patent number CN 109537714 A, a device for dredging the interior of a consolidation pipeline is disclosed, which relates to the field of municipal construction. The device for dredging the interior of a consolidation pipeline comprises a dredging rotary head, the interior of the dredging drill bit is hollow, one end of the dredging drill bit is provided with an obstacle removal device, the other end of the dredging drill bit is connected to a high-pressure driving device, the high-pressure driving device is provided with a mixture adsorption device, and the obstacle removal device comprises a conical high-pressure nozzle, a spray gun mouth and obstacle removal convex teeth. The device for dredging the interior of a consolidation pipeline, the dredging drill bit can be used to perform water flow impact and drilling cleaning operations on the sediment consolidated inside the sewage pipeline by using the obstacle removal convex teeth in conjunction with the conical high-pressure nozzle during the rotation process, and can effectively clean and dredge the dry and consolidated dirt in the urban sewage pipeline, effectively solving the problem of urban waterlogging caused by the blockage of dirt in the urban sewage pipeline. The device does not require manual entry into the drainage pipeline for dredging operations, which effectively saves manpower.

[0005] During use, it can only be driven electrically. In some more complex environments, electric drive cannot keep the device stable. At the same time, because auxiliary structures are installed on the device, the clearance route cannot be guaranteed to be stable during the clearance process. Therefore, high-pressure hydraulic-driven micro-pipeline clearing and obstacle removal devices are now needed. Utility Model Content
