Repairing device and method for urban underground drainage pipeline

Abstract

The invention discloses a repairing device for an urban underground drainage pipeline. The repairing device includes a disk-shaped horizontal plate, a horizontal column and a capacity box fixedly sleeving the horizontal column, a clearing device for clearing impurities on the inner wall of the pipeline is installed on the horizontal plate, and the side wall of the capacity box is fixedly connectedwith a repairing mechanism for repairing the underground drainage pipeline. The invention further provides a repairing method of the urban underground drainage pipeline. The repairing method includesthe following steps that S1, a body of the repairing device is placed in the underground drainage pipeline; and S2, the height of a telescopic rod on the horizontal plate and a limiting pin and a pinhole on a sleeve and a hollow pipe are adjusted to adjust the heights of a brush and an arc-shaped block. According to the repairing device and method for the urban underground drainage pipeline, theinner wall of the pipeline is cleared and then cleaned through a cleaning device, the pipeline repairing effect is ensured, through arrangement of a motor, the repairing mechanism can be driven to rotate to make pipeline repairing more uniform, the clearing height and repairing height can be adjusted by the clearing device and the repairing mechanism, and the repairing device is suitable for drainage pipes with different pipe diameters and sizes.

Description

technical field [0001] The invention relates to the field of urban construction, in particular to a repair device and method for urban underground drainage pipes. Background technique [0002] Urban drainage pipes are called the "underground lifeline" of the city. They shoulder the important tasks of urban sewage and waterlogging. With the rapid development of cities, underground pipes have been laid continuously and rapidly. However, as urban underground pipes increase in service life, The use function of the pipeline cannot meet the actual needs due to urban development, the pipeline is subjected to electrochemical corrosion of the soil layer, the structural damage or aging degree is increasing, and the structure and strength of the pipeline cannot meet the operating requirements. [0003] Most of the existing urban drainage pipeline repairs have been repaired inside the drainage channel. Before the repair, the inner wall of the pipeline needs to be cleaned and repaired. T...

[0002] Urban drainage pipes are called the "underground lifeline" of the city. They shoulder the important tasks of urban sewage and waterlogging. With the rapid development of cities, underground pipes have been laid continuously and rapidly. However, as urban underground pipes increase in service life, The use function of the pipeline cannot meet the actual needs due to urban development, the pipeline is subjected to electrochemical corrosion of the soil layer, the structural damage or aging degree is increasing, and the structure and strength of the pipeline cannot meet the operating requirements.

[0003] Most of the existing urban drainage pipeline repairs have been repaired inside the drainage channel. Before the repair, the inner wall of the pipeline needs to be cleaned and repaired. The existing cleaning device is to clean the inner wall of the pipeline through high-pressure spray guns and other devices, but There will be impurities remaining on it after cleaning, which will affect subsequent repairs. In addition, the existing urban underground drainage pipeline repair method is to repair after the pipeline cleaning device is cleaned. There are many devices carried, and the devices need to be installed one by one. It is a waste of time to transport more and more pipes to the pipeline. This method is more troublesome when there are a large number of pipelines in the city that need to be repaired.
