Description

The present invention relates to a kind ofly drain deep under ground by one or more devices that are contained in the water that underground gutter collects by siphon.

Traditionally, draining or draw water by the filtering head of linking vacuum pump and to realize, otherwise may the time by overcoming centrifugal force by underground horizontal drainage, rhone, draining wall or spout realization, under the situation of need with rhone or draining wall, if can not overcome centrifugal force, then draw water with pump.

These schemes exist critical defect simultaneously.Draw water and be subjected to the restriction of the user's set that must use.Because the position of required gradient and underground level, and be subjected to the water-bound layer to soak into efficient the slip low and face of land to have disconnected these drainage pipes, so concerning drainage pipe, produced rig and can meet the requirements of problem.

Rhone only can be paid attention to when 4 meters of depth capacitys.Draining wall (growth of rhone) need be same with molded wall mounting technique, thereby be expensive, and the only limited efficient of draining spout.

In French Patent (FRP) 737965, considered to occur too much at need when boring, with underground horizontal drain pipe road and the vertical drainage pipeline of dependence siphon drainage or the possible alternative of drain hole, but do not provide example or or even real the description.For priming charge, a described siphonal end must be connected on the valve, water can be flowed out and do not allow air enter, and priming charge or reset the waterflooding requirement syphon and the aspirator of water pump or vacuum pump links, and after draining acquires a certain degree, this syphon stops automatically, frequently (every day) reset by the operating personnel that have portable or fixed hand pump, carry out suction operation unless the aspirator that motor drives permanently is installed.The result of this technology is that the water surface alternately rises, descends, and it and desirable soil stability run in the opposite direction.What is more, because the drain hole for the treatment of siphon must be positioned at the place that often being difficult to of differing widely arrives, and it is considerable to be used for the equipment and the personnel Equivalent of trouble hunting and supervision, so this technology has been abandoned, although it is very high to make way for aforesaid cost, more cheap comparatively speaking scheme.

The object of the present invention is to provide a kind of can forever and independently work, do not need priming charge, thereby the siphon drainage device that does not need to repeat to keep in repair and often monitor, to overcome the shortcoming of the prior art of discussing just now.

By following description as can be seen the present invention constitute the feature of claim content and clear and definite advantage, can understand better with reference to the accompanying drawings, wherein:

Fig. 1 illustrates the principle of siphon drainage device of the present invention with the section sketch map;

Fig. 2 sets up the device example that is used to drain the infiltration of inclined route upstream of the present invention with the profile perspective demonstration.

In following content, the present invention is described with the example that drains the upstream infiltration that is positioned at the inclined route that slides easily on ground.Very clear, this example is restrictive absolutely not, and the present invention can be applied under many other situations, and this point is clearly for the skilled people of art technology.

Drainage pipe is vertical among Fig. 1, but from all being feasible to any gradient the level vertically, its operating principle does not change.This gutter or be placed in the pre-drilled hole is perhaps smash or is inflated and place underground by hammering, shake according to known technology.It is made of a pipe made from the plastic material that for example is fit to its purposes basically.This root pipe has on its most length and forms screen filter, and correctly says by its function and to represent this gutter, worn the part 1 in hole.The low side of pipe seals, and its sidewall is entity, is accumulator 2 to form a cup.The pipe top has the cylindrical portions may of the solid side wall 4 of a band upward opening.This upper part 4 also comprises at least one side pipe 5, and exposes the top in manhole, covers with lid 7 usually, forms a manhole that has habitual key very expediently.Be subjected to water layer 9(Fig. 2 from the upstream) infiltration pass screen filter part 1 and enter gutter, and, meanwhile reduced the water level of downstream water layer (being designated as 10) with its a certain plane of filling with the top edge that is higher than cup 2.

In this pipe, the low side 3 of a syphon 6 is immersed in the cup 2 all the time, in gutter, upwards extend, and draw by side pipe 5, after that may exist through one section, basic horizontal, as to cross over this road changeover portion 11, drop to an outlet of its end 8, terminal 8 level height is identical with the plane of cup 2 top edge, and cup 2 is not by this siphonic effect emptying so that siphonic effect can take place.

Pressure and other cavitations and the phenomenon of bleeding considering atmospheric pressure, in syphon 6, lose, in order to work reliably, the peak that should be noted that pipe 11 respectively and the difference in height between the water surface in the well at the upper plane of cup 2 and the port of export 8 or the port of export 8 places or pond not above 9 meters.

Can be clear that by above-mentioned, because the end 3 of syphon 6 is immersed in the cup 2 that can not be drained all the time, siphon is inoperative in this side till the ass ascends the ladder, even the water level of water layer 9,10 is reduced to the horizontal plane of cup 2 top edge, perhaps when arid season is reduced to lower water level, still like this.In this case, siphon is obviously no longer carried out, because no longer include the water that need drain, but as soon as new infiltration enters the trend that gutter and water level have rising, siphon will recover its activity automatically.

Be inhaled into the problem of syphon 6 owing to exist air from the port of export 8, allow terminal 8 to have the structure that upwarps, for example the crotch-shaped shown in the accompanying drawing can be avoided this problem.Similarly, still be arranged on this end 8 in the place that required water-head is provided as mentioned above, can be placed in the well such as the such known type of overflow well, perhaps be placed in the drain, this drain can keep its water level with common drawing water when needed.

As has mentioned the front, under extreme case, cavitation might take place and the phenomenon of bleeding, and produce air pocket at pipe 6 tops in syphon 6, operate as normal is had a negative impact.These phenomenons depend on the inner surface situation and the siphon speed of syphon 6 to a great extent.Therefore, the pipe that preferably uses for example on record RILSAN types of material of plastic material to make, this pipe provides fabulous result.

Have again, according to the peculiar underground water situation of soil itself, can be with the parallel side by side installation of the syphon of two or three different-diameters, they remedy mutually according to ambient conditions local and/or at that time.

In addition, one or more syphon covers in protective sleeve at transition portion 11 with to lower part 12 valuably from the outlet of gutter by side pipe 5, and protective sleeve itself is protected in a pipe trench with traditional husky fixation.The buried depth of pipe trench and side pipe 5 or export 8 the degree of depth and should be enough to antifreeze with respect to the face of land.

It may be noted that, just now the technology of being narrated allows gutter to use in isolated mode, perhaps leading to one with parallel connection perhaps is that the mode of the public outlet in overflow well is used, perhaps with cascade system, promptly a upstream row water pipe is used by the mode that siphon enters a downstream row water pipe, all these operational modes can combine with any method of suiting measures to local conditions, and comprise with traditional underground horizontal drain pipe using jointly.

Just as already mentioned, also have residual water level in cup 2, this just prevents that syphon is inoperative, and as soon as infiltration occurs this water level is raise, and just makes syphon get back to circulation status.

For initial priming charge, three kinds of possible schemes are arranged: gutter is injected into supplementing water is higher than syphon 6 up to water level peak, perhaps bleed in siphonal outlet 8, perhaps preferably can inject water from exporting 8, its advantage is to drive the whole air that exist in the syphon away.

When siphon drainage pipe of the present invention is inserted when underground at arid season, they can start by water filling immediately, as what mentioned, in case and they are ready to rise above the top edge of cup 2 at the water level of wet season water layer, just go into circulation, this is a significant advantage with respect to traditional siphon technology with having no obstacle.
