Device for dredging blockage body of tunnel drainage pipe in combination with chemical solvent

Abstract

The invention discloses a device for dredging a blockage body of a tunnel drainage pipe in combination with a chemical solvent. The device is formed by connecting a blockage body crushing and dissolving device arranged in a pipeline and a liquid conveying device outside the pipeline; according to the blockage body crushing and dissolving device, a walking chassis and a motor are controlled to work through a PLC, the blockage body in the pipeline is cut and crushed section by section, and the ideal blockage body crushing effect can be achieved through the arrangement mode of a scraper type cutterhead and water-drop-shaped through holes; and meanwhile, necessary conditions are provided for blockage body chippings to enter an outer shell for full reaction, the liquid conveying device supplies a prepared chemical solvent to corresponding parts, the cut blockage body is subjected to full anti-dissolution, and the blockage body is changed into a liquid body to be discharged out of the device. According to the device, the output power of the cutter head, the spraying amount of the chemical solvent and the driving speed of the chassis can be adjusted in real time according to different pipeline blockage conditions, high automation and intelligence are achieved, and the application range of the device is widened.

Description

technical field [0001] The invention belongs to the technical field of tunnel drainage pipe dredging devices or equipment, and in particular relates to a device for dredging tunnel drainage pipe blockages in combination with chemical solvents. Background technique [0002] Due to the extensive use of concrete materials in tunnel construction, in areas with abundant groundwater, water infiltrates into concrete materials and carries calcium ions to precipitate, and with CO in water 3 2- and HCO 3 - The reaction produces insoluble substances such as calcium carbonate, which enter the tunnel drainage system with the water flow. Since there is no external pressure in the drainage system and the flow rate of water is small, insoluble substances such as calcium carbonate have good adhesion to the pipe wall of the tunnel drainage system. Groundwater cannot be discharged, lining strength is reduced and cracked, tunnel outage and other disasters. [0003] In addition, since the t...

AI Technical Summary

Problems solved by technology

Since there is no external pressure in the drainage system, the flow rate of water is relatively small, and insoluble substances such as calcium carbonate have good adhesion to the pipe wall of the tunnel drainage system. Groundwater cannot be discharged, lining strength is reduced and cracked, tunnel outage and other disasters

[0003] In addition, because the tunnel lining is a concealed project, it is inconvenient to repair after damage, and the accumulation rate of insoluble substances will become faster and faster with time
