Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of municipal drainage pipe, specifically relates to a municipal drainage pipeline. BACKGROUND

[0002] As a key component of the system, municipal drainage pipeline undertakes the heavy responsibility of collecting and transporting urban sewage and rainwater. However, during actual operation, the elbow part of the drainage pipeline frequently appears to be blocked, which brings many troubles to urban drainage.

[0003] As a component that changes the direction of water flow, the elbow is extremely prone to blockage due to its special structural design. When water flows through the elbow, the direction changes sharply, and the water flow speed decreases instantaneously, causing various solid impurities carried in the water, such as silt, leaves, household garbage, and industrial waste, to deposit at the elbow due to the lack of sufficient power. At the same time, the turbulent flow state formed by the water flow at the elbow makes it easier for impurities to adhere to the inner wall of the pipeline. With the accumulation of time, these sediments gradually increase, eventually leading to pipeline blockage. Elbow blockage not only affects drainage efficiency and causes urban waterlogging, but also may cause sewage overflow, causing serious pollution to the urban environment and breeding a large number of bacteria and mosquitoes, which endanger the health of residents.

[0004] Currently, to address the problem of elbow blockage of the drainage pipeline, artificial regular cleaning or the use of simple mechanical dredging tools is usually adopted. The internal space of the elbow is relatively narrow, and conventional cleaning tools are difficult to operate flexibly therein, making it difficult to reach the blocked position and clean the interior of the elbow.
