Description

Technical Field

[0001] The utility model relates to the technical field of urban drainage pipelines, in particular to a multifunctional pipeline cutting device. Background Technique

[0002] Urban drainage pipelines often encounter the following situations: 1. Encapsulated concrete in the pipeline overflows into the pipeline joint through the interface. After a long time, it becomes a caked block, seriously affecting the water flow in the pipeline; 2. Other foreign objects penetrate into the pipeline, such as anchor roots, steel bars, or tree roots, etc., affecting the water flow in the pipeline. Some sundries will be blocked when passing through, and over time, obstacles in the pipeline will be formed; 3. In the pipeline with a hidden branch pipe, when the whole section of the lining is repaired, it is necessary to cut the hidden interface to ensure the normal operation of drainage.

[0003] Due to various situations that are likely to cause blockage of drainage pipelines, the probability of drainage pipeline blockage is quite high, and it is necessary to often dredge and clean the drainage pipelines. However, currently, when dredging and cleaning drainage pipelines, high-pressure water flushing is usually used to remove various solid wastes, sand, soil, etc. in the pipeline. During cleaning, the flushing water flow selects a high-strength water pressure and adds a special cleaning agent, which can effectively flush foreign objects in the pipeline. However, for some relatively stubborn and difficult-to-remove foreign objects such as caked blocks and anchor roots, it is very difficult to effectively clean them. Content of the Utility Model
