(2) A hydraulic flushing method: the method requires that the sludge in the drainage pipeline is not too much, and the blockage is directly washed by utilizing water with larger flow rate to pass through the blockage area, but the method is easy to cause new silting blockage of the upstream drainage pipeline. (3) Manual clearing method: the staff dredges through handheld tool at the inside manual work of pipeline, and some serious pipelines of jam can be cleared up to this method, but the space of pipeline is narrow, and the personnel of dredging crouches and can't carry out high-efficient mediation inside the pipeline, and staff's intensity of labour is big, and the cost of labor is high, has very big potential safety hazard simultaneously. (4) A high-pressure water jet dredging method: the method is characterized in that a special waterwheel engine drives a high-pressure water pump to pressurize water in the waterwheel, then the water is pressed to a nozzle, unidirectional reaction thrust is formed by means of water jetting of the nozzle to push the nozzle and a rubber pipe to move in a pipeline, the inner wall of the pipeline is washed while the nozzle and the rubber pipe move, and the high-pressure water jet dredging method is suitable for pipelines with various diameters, but the method can only be used for blocking a non-serious drainage pipeline and is low in dredging efficiency.
With the continuous expansion of urban scale, the problem of blockage and silting of drainage pipelines is becoming more and more serious. The blockage condition of the drainage pipeline is aggravated due to diversified blockage garbage in domestic drainage pipelines, such as kitchen garbage, construction garbage of construction units, concrete blocks and the like, thick hardened hard scale is arranged on the inner wall of the drainage pipeline, dredging of underground pipelines can not be effectively conducted through a winch dredging method, a hydraulic flushing method and a high-pressure water jet dredging method, the pipelines can only be dredged or broken and disassembled manually, if the blockage pipelines are directly excavated and replaced, the large engineering is needed, multiple departments are coordinated, the construction period is long, the cost is higher, and the normal operation of traffic is seriously influenced.
