Definitions

  • the present invention relates to a device for equipping the outlet end of a drain siphoning pipe in order to allow this siphoning pipe to operate continuously or intermittently at a flow rate greater than a minimum critical flow rate determined by the conditions prevailing on the site.
  • Patent FR 593 203 and patent application EP 0 230 918 propose a siphon drainage device capable of operating permanently and autonomously without the risk of defusing and therefore not requiring repeated interventions or systematic monitoring.
  • the water pumped by siphoning comprises a significant proportion. dissolved gas.
  • the pressure decreases and part of the gas is released and causes the formation of bubbles.
  • These bubbles are entrained by the stream of water as long as it is strong enough.
  • the bubbles are no longer entrained by the current of water, they all go up to the high point of the siphon, meet there and create a single bubble by coalescence.
  • the bubble which stagnates at the top point of the siphon does not occupy the entire section of the pipe at the start and allows a certain flow of water to pass for a certain time, up to 'so that, by coalescence, it is large enough to stop the flow.
  • the present invention aims to overcome by proposing a device capable of operating continuously and autonomously without risk of defusing, without supply of external energy, not requiring d '' repeated interventions or systematic monitoring, and allowing the automatic stop of the operation of the siphoning pipe when the flow drops to reach the critical flow, and the automatic restart of the siphoning for a predetermined hydrostatic charge in the site to be drained.
  • the invention is exposed by taking the example of the drainage of a slope on a slope site where the ground is likely to slide, the drain being placed in a borehole. It is clear that this example is in no way limiting and that the invention can find its application in many other cases, depending on the specificity of the sites, as will appear to those skilled in the art.
  • the drain shown in FIG. 1 is vertical, but any inclination relative to the vertical giving downward penetration of the drain upstream is possible without the principle functioning being changed.
  • the drain represented is placed in a borehole, but as said above, could as well be beaten, vibrated or launched, depending on the known techniques. It consists of a first tube 1, for example of plastic material suitable for this use.
  • the tube 1 comprises over the part of its length intersecting the water inlets, a part provided with perforations and forming a strainer, and representing by its function the drain itself. At its lower end, it is preferably closed by a foot plug 2 preventing material from rising through the bottom of the drain. Between the tube 1 and the side walls of the borehole, a filter-forming material 3 can also be placed.
  • a second tube for example made of plastic material suitable for this use.
  • This tube comprises over a part of its length a part 4 provided with perforations and forming a strainer, possibly protected by a second filter (not shown).
  • the second tube is closed, and its walls are full to form a bowl or reservoir 5.
  • a tubular part with solid walls 6, terminated in the upper part for example by a device comprising at minus a substantially radial lateral outlet, and advantageously, according to site practice according to the specific conditions of the site, four radial outlets arranged in a cross 7 to allow access and mechanical support for the adequate outlet of a siphoning pipe 11
  • This top part is advantageously placed in a manhole.
  • the siphoning pipe 11 dips permanently by its lower end 12 in the bowl 5 of the second tube mounted inside the strainer part 4 and the solid part 6 of this second tube to come out of it by one of the side conduits of the top part 7 and, after a possible intermediate section which can be close to the horizontal, go down again through a pipe 9 preferably without climatic influence, towards an outlet at its end located, in altitude, at the level of the upper edge of the bowl 5 so that the siphoning can play without this bowl 5 can never be emptied by the siphon effect.
  • the end 13 of the siphoning pipe 11 can be, as provided in the state of the art already mentioned above, placed in an outlet manhole 10. According to the invention, the end 13 of the siphon pipe swim it is at the upper edge of the bowl 5 and is connected either directly or preferably by a swivel connector 19 on a rigid tube 14.
  • This rigid tube 14 can rotate around a horizontal axis 15 carried by a support 20 by the effect of a counterweight 16, the stroke of this tube being limited upwards and downwards, by a high stop 17 and a low stop 18.
  • the initiation of the siphon can be done by injection of water by the end of the rigid tube 14, until the siphoning pipe 11 is completely purged of its air and the position of the water in the drain at least one meter above the horizontal passing through the end 13 of the pipe 11.
  • the stopping of the water injection and the loading of the water in the drain relative to the end 13 of the siphon causes the drainage device to function.
  • the end 13 of the siphoning pipe. 11 before it reaches the level of the axis of rotation 15 is provided with a flexible U-shaped part fa promoting free movement up and down of the rigid pipe 14.
  • the weight of the water in the rigid tube 14 being motor relative to the counterweight 16, this tube is placed against the lower stop 18.
  • the siphon then flows at a flow higher than the critical flow mentioned above.
  • the imbalance will occur for a sufficient load in the drain allowing the flow beyond the critical flow until a possible new shutdown period.
  • the water entering the drain at atmospheric pressure, comprises a certain proportion of dissolved gas.
  • the siphoning pipe 11 When the water rises in the siphoning pipe 11, its pressure decreases, and gas bubbles appear. As long as the flow speed is sufficient, these bubbles are evacuated by the stream of water. On the other hand, at the critical flow, the bubbles are no longer evacuated.
  • the rigid end tube 14 empties, the bubbles of the siphoning pipe 11 all rise in the region of the high point.
  • the siphoning pipe 11 is constantly submerged in the bowl 5 which can never empty, the siphon can in no case be defused on this side, even when it is not there is more water in the borehole, for example in dry periods, the water levels always remaining at least at the level of the upper edge of the bowl 5.
  • the siphon will obviously no longer be active since there will be no more water to drain; but as soon as new infiltrations will occur in the drain and allow by the induced load the rise of the water in the rigid end tube 14, then its tilting, then the siphoning pipe 11 will become active again.
