Description

Technical Field

[0001] This utility model relates to the field of underground pipeline repair technology, specifically a trenchless repair device for municipal underground pipelines. Background Technology

[0002] With the acceleration of urbanization, underground pipelines, as key infrastructure for transporting liquids, gases or loose solids, are widely distributed underground in cities. However, underground pipelines are subject to various pressures, corrosion and geological changes over a long period of time, making them prone to cracks, gaps and other damage, which seriously threaten their normal operation and thus affect the orderly operation of the city.

[0003] Traditional pipeline repair methods often require large-scale excavation, which is not only costly and time-consuming but also causes significant disruption to the surrounding environment and traffic. To address this challenge, trenchless repair technology has emerged, and trenchless repair devices for municipal underground pipelines are gaining increasing attention. One typical device consists of a remote-controlled vehicle equipped with a storage tank and a pump. The pump is connected to a flow guide, and the vehicle has an electric push rod and a leveling roller underneath. In operation, the vehicle is positioned above the damaged area, and the pump pumps the repair fluid from the storage tank, which is then dripped through the flow guide onto the damaged area at the bottom of the pipe. The leveling roller and electric heating box then complete the subsequent operations. However, this device has significant limitations. Because pipelines are circular and deeply buried underground, the location of the damage is highly random. The flow guide lacks angle adjustment capabilities. If the damage is located above or to the sides of the pipeline, the flow guide, which cannot be flexibly turned, cannot accurately guide the repair fluid, making repair work impossible. This greatly reduces the device's practicality in handling complex conditions and fails to meet the diverse needs of current municipal pipeline repair. Therefore, we propose a trenchless repair device for municipal underground pipelines. Utility Model Content

[0016] A trenchless repair device for municipal underground pipelines is provided, which has the following beneficial effects:

[0017] 1. Precise Repair: Through the coordinated operation of the angle adjustment motor, electric telescopic rod, and rotation drive motor in the spray adjustment component, the angle and position of the guide nozzle can be flexibly adjusted. Whether it is above, below, or on both sides of the pipeline, the repair fluid can be precisely sprayed onto the damaged point.
