Waterpower automatic silt-washing device of inverted siphon in pressure water delivery pipe
The invention discloses waterpower automatic silt-washing device of an inverted siphon in a pressure water delivery pipe. The waterpower automatic silt-washing device comprises a horizontal silt-absorbing tube, a vertical mud-delivering tube and a ground surface mud-discharging tube. The horizontal silt-absorbing tube is arranged at the bottom of the inverted siphon in the pressure water delivery pipe, the two ends of the horizontal silt-absorbing tube are closed, silt-absorbing holes are formed in the periphery of the tube wall, and the total area of the openings of the silt-absorbing holes is smaller than the area of the cross section of the horizontal silt-absorbing tube. The vertical mud-delivering tube is arranged in a water-discharging silo of a pressure water delivery pipeline, the bottom end of the vertical mud-delivering tube is communicated with the horizontal silt-absorbing tube, the top end of the vertical mud-delivering tube is communicated with the ground surface mud-discharging tube, and the height of the vertical ground surface mud-discharging tube is smaller than that of a pressure water head in the inverted siphon. The ground surface mud-discharging tube is located on the ground surface, one end of the ground surface mud-discharging tube is communicated with the vertical mud-discharging tube, the other end of the ground surface mud-discharging tube is starched into a ground surface mud-discharging site, and a mud-discharging valve is arranged on the ground surface mud-discharging tube and is capable of controlling silt discharging. According to the waterpower automatic silt-washing device of the inverted siphon in the pressure water delivery pipe, waterpower automatic silt washing device on the inverted siphon in the pressure water delivery pipe can be achieved under the condition that tunnel emptying, labor decontamination or power decontamination are not needed, and the advantages of being safe, energy-saving, good in silt-washing effect, small in operation influence and convenient to construct are achieved.
