AI Technical Summary
Technical Problem
[0003]现有的非开挖清淤方式包括高压射流水清洗以及机械疏通，当管道内有石头之类的固体物时，无法通过高压射流水清洗将固体物带出至管外，机械疏通则容易破坏管壁，并且对软性淤泥的清理效果较差
Benefits of technology
本实用新型的清淤组件由第一射流基座、第二射流基座和气囊组件共同构成，在移动的过程中，第二射流基座对污水管道的内壁进行一次冲刷，气囊组件再次对污水管道的内壁进行清理并带动管内固体物移动，第一射流基座对污水管道的内壁进行二次冲刷，通过对管内壁进行多次清理，提高了清淤质量。

Abstract
The utility model discloses a kind of sewage pipeline non-excavation dredging devices, including high-pressure water jet dredging assembly and air bag assembly, the high-pressure water jet dredging assembly connects water pipe, the high-pressure water jet dredging assembly and air bag assembly are used to carry out dredging to sewage pipeline main body, the high-pressure water jet dredging assembly includes first jet base and second jet base, the first jet base is communicated with second jet base by communicating pipe, the air bag assembly includes fixed seat and air bag main body. The utility model relies on the reaction force of high-pressure water flow and drives the whole dredging device to move, dredging is carried out in pipe, the inner wall of sewage pipeline is flushed once by second jet base, air bag assembly is cleaned again to the inner wall of sewage pipeline and drives solid object in pipe to move, the inner wall of sewage pipeline is flushed twice by first jet base, when dredging device moves out of sewage pipeline, solid object is taken out together.
