Description
Technical Field
The invention belongs to the technical field of municipal drainage, and relates to a pipeline sediment dredging and dredging method.
Background
The drainage pipeline is an engineering facility for collecting and conveying urban domestic sewage, industrial wastewater and rainwater. In recent years, with the acceleration of the urbanization process of China, the number and scale of the construction of drainage pipelines are increased year by year. Such as: in the thirteen-five period, the offshore city has the matched drainage pipeline of about 100 km in the central urban area and the newly-built drainage pipeline of about 310 km in the suburban area on the basis of the drainage pipeline with the total built length of about 9530 km. Increasingly perfect drainage pipeline systems provide convenience for conveying various sewage and rainwater in cities and towns, however, along with the gradual bulkiness of the drainage pipeline systems, the problems of water pollution, secondary disasters and the like of drainage pipelines are gradually obvious.
Taking a split-flow rainwater pipeline as an example, under the background of repeated rain and sewage mixing, random drainage of car-washing gear sewage and large amount of initial rain water surface source pollution, the rainwater pipeline becomes a collection place of a plurality of sewages, and the sewages are drained into rivers and lakes when being released into rivers in rainy days, thereby causing huge impact on water environment. For a split-flow sewage pipeline, the content of suspended particles in the sewage conveyed by the split-flow sewage pipeline is high, and sludge is easy to precipitate in a form in a pipe section with a large pipe diameter and a slow flow speed, so that the pipeline is blocked. For the combined drainage pipeline, the flow velocity of sewage in the pipeline with larger pipe diameter is slower in dry days, and suspended particles in the sewage are easy to precipitate to form sludge; in rainy days, due to the fact that the water quantity is increased sharply, sludge in the pipeline is flushed out, and therefore the problems of black and odorous rivers and lakes are frequently caused.
At present, aiming at the situation that dredging of a drainage pipeline is only limited to the situation of small pipe diameter, methods such as a high-pressure washing gun, manual traction or push-pull and the like are generally adopted to clean particles and sludge in the drainage pipeline out of the pipeline or push the particles and sludge to the pipeline with larger pipe diameter. However, no effective desilting and deslagging technology exists for the drainage pipeline with a large pipe diameter.
In addition, when the high-pressure washing gun is used for washing the sludge in the drainage pipeline, the washing effect is weakened due to the existence of components with larger particle size and harder texture in the sludge, and the washed sludge damages the pumping equipment due to the existence of hard components. Therefore, if the sludge in the drainage pipeline can be damaged before dredging, the flushing efficiency of the high-pressure flushing gun can be effectively improved, and the damage of a suction pump in the sludge pumping and collecting vehicle can be effectively avoided.
Therefore, the market is in need of a novel dredging technology capable of breaking hard components in drainage pipeline sludge.
