Description

Technical Field

[0001] This application belongs to the field of drainage pipeline technology, and more specifically, relates to a drainage pipeline anti-settlement device. Background Technology

[0002] Traditional drainage and settlement prevention methods often involve using a large pipe inside a smaller pipe and filling the gap between the two pipes with foam sealant. This method can solve the settlement problem of drainage pipes to some extent. However, when the ground settles unevenly, the sealing foam sealant adheres tightly to the drainage pipe and cannot fall off or be damaged as the drainage pipe settles as a whole. This leads to the leakage of foul odors and the overflow of wastewater from the drainage pipe, which pollutes the air and the environment. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of this application is to provide a drainage pipe anti-settlement device with a simple and compact structure, which can rotate or move horizontally when the ground settles, thereby reducing the risk of damage to the drainage pipe.
