Description

Technical Field

[0001] The utility model belongs to the technical field of equipment or devices for treating crystallization blockage in tunnel drainage systems, and in particular relates to a device for clearing blockage in tunnel drainage pipes. Background Art

[0002] In areas rich in groundwater, shotcrete has poor impermeability and is constantly corroded by corrosive groundwater in the early stages of construction. Groundwater easily penetrates shotcrete and invades the interior of the tunnel, affecting the durability of the tunnel structure and the construction process. In shotcrete, the gel material is continuously hydrated to produce hydration products such as calcium hydroxide and hydrated calcium silicate. When groundwater rich in corrosive ions continuously passes through the interior of the concrete, it dissolves the calcium ions in the concrete, causing the calcium ions to flow into the tunnel drainage system along with the corrosive liquid, accelerating the crystallization and blockage of the drainage system. This process is called the "calcium dissolution crystallization" phenomenon of tunnel shotcrete.

[0003] The calcium dissolution effect of shotcrete makes the groundwater solution flowing into the drainage system rich in calcium ions and other precipitates, which are easily combined with bicarbonate or carbonate ions to form calcium carbonate crystals attached to the surface of the drainage pipe, which causes the drainage pipe to be blocked over time. The blockage of the drainage system prevents the groundwater behind the lining from being discharged in time, and then acts on the outside of the support structure and the bottom of the road surface in the form of pressure, causing the lining and the road surface to bear additional additional water pressure, resulting in a large number of tunnels. Shortly after the construction, the lining cracks, water leakage and water on the road surface have appeared, seriously endangering the safety of tunnel operation.

[0004] At present, the technology for treating blockage in tunnel drainage pipes usually adopts tool cutting and high-pressure water dredging. However, the existing high-pressure water dredging device cannot turn at the bend of the drainage pipe and can only dredge locally along the direction of a single pipe.

[0038] The working principle of the utility model is as follows:

[0039] When in use, put the sleeve 3 and the high-pressure water pipe 4 into the longitudinal drainage pipe. Under the action of the self-propelled nozzle 5, the high-pressure water pipe 4 and the sleeve 3 move forward together, and the high-pressure water sprayed forward impacts and crushes the crystals in the longitudinal drainage pipe. At the same time, the industrial endoscope 6 transmits the image in the longitudinal drainage pipe 6 to the external host computer. When the operator observes the appearance of the annular drainage pipe and the transverse drainage pipe, the operator operates the external host computer to send a signal to the PLC controller 2-3, which controls the high-pressure water pump 2-2 to stop supplying water, and at the same time gives a signal to the wire-retracting motor 2-8. The wire-retracting motor 2-8 works, controls the contraction line 3-1 to shorten, and the sleeve body 3-2 is compressed. The end of the high-pressure water pipe 4 leaks out of the sleeve body 3-2, and the sleeve body 3-2 shrinks to the required After reaching the position, the PLC controller 2-3 sends signals to the turning motors 2-7 corresponding to two of the high-pressure water pipes 4. Different speeds are set for the four turning motors 2-7. The turning motors 2-7 control the contraction of the turning line 4-4 and use the differential speed to turn the high-pressure water pipe 4 until it is aligned with the annular drain pipe. The turning motor 2-7 stops working and the high-pressure water pump 2-2 starts to supply water. At this time, one group of high-pressure water pipes 4 goes straight in the longitudinal drain pipe, and the other two groups advance in the annular drain pipe and the transverse drain pipe respectively, so as to use the impact force of high-pressure water to clear the crystal blockage in the annular drain pipe and the transverse drain pipe. After cleaning, the casing 3 and the high-pressure water pipe 4 withdraw from the drain pipe together. After the casing 3 is reset, it re-enters the next section of the drain pipe for cleaning.
