Background technology

In open slope, road and rail side slope etc., be often rich in a large amount of ponding, its source mainly comprises that the ponding in rainwater infiltration, upper slope or massif infiltrates, even comprises the number of ways such as stream pours into.Side slope internal water accumulation Upon Slope Stability is very unfavorable, is mainly manifested in: the intensity under (1) general rock dry state often its full water state intensity 1-2 doubly, therefore dry slope stability is apparently higher than moisture side slope; (2) there is the feature of meeting cement, disintegration in rocks as many in granite porphyry, mud stone, conglomerate, montmorillonite etc., and therefore its rock mass strength reduces rapidly, and slope stability decreases; (3) structural belt causes the key of slope instability often, and rock crushing in structural belt, containing fault gouge, has obvious rainwater argillization feature, and its frictional resistance will reduce rapidly thereupon; (4) in side slope, water content increases, and will cause side slope deadweight to increase, and unstability trend increases.As the landslide that heavy rain causes later, all stem from above-mentioned reason.Therefore, drainage side slope internal water accumulation to greatest extent, to safeguarding that the stability of side slope has very important effect.

The method of drainage open slope internal water accumulation generally has two kinds, and the one, in side slope, cut a hole lateral aperture (aperture is slightly downward-sloping in order to draining), in hole, settle gutter, ponding flows out automatically; Another kind is cutter upright opening, adopts the methods such as suction pump to extract out.First method is a kind of water discharge method of commonly using, its deficiency is that construction cost is high, timely construction drainage hole in the process that must form in side slope, if miss the best construction period, once side slope forms, and because of no operatton platform, almost cannot supplement cutter drain hole, it is distant with drainage area distance that second method is applicable to side slope surface distance, and lateral aperture drainage distance is long, the great side slope of difficulty of construction is hydrophobic; Or infiltration appears in the slope excavation later stage, personnel and equipment are difficult in established steep side slope construction, can only be in the region of side slope step construction.Employing upright opening is hydrophobic, shortcoming is as follows: (1) adopts submersible pump that the ponding oozing out in weep hole is extracted out conventionally, not only to spend a large amount of manpower and materials and set up power cable in cheating in the open, also must there be special personnel to be responsible for the operation of submersible pump, if field road and rail side slope is hydrophobic for a long time, this kind of method performance difficulty is larger; (2) general submersible pump lift is directly proportional to pump housing diameter, and small size pump lift is little, must adopt large volume pump could meet the hydrophobic requirement of side slope, therefore must adopt the large diameter holes such as φ 265mm, has the defects such as cost is high, speed of application is slow of punchinging; (3) submersible pump of installing in vertical weep hole is generally clarified water pump (slag stock pump volume is large), and because dirt in hole is more, loss is very large; (4) infiltration of vertical weep hole internal water accumulation is a process slowly, is a process faster and draw water, if mismanagement, suction pump is easy to because of idle running scaling loss.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described further, but protection scope of the present invention is not limited to the scope of following described detailed description of the invention.

Specific embodiment one

Fig. 1-3 are the schematic diagram of slope drainage system.This side slope automatic drain system mainly comprises three bigger devices: energy storage device, flip flop equipment and dewatering installation.

As shown in the figure, energy storage device comprises storage tank 3, accumulation of energy case 4, and the communicating pipe 17 between accumulation of energy case 4 and storage tank 3, the outlet pipe 11 being communicated with gutter 19, in addition, in order to ensure that the interior current of accumulation of energy case 4 can discharge smoothly and flow into, in energy storage device, can also arrange one and be positioned at the air inlet pipe 5 being communicated with atmospheric pressure on accumulation of energy case.

Flip flop equipment comprises suspension cylinder 20, rigidity float lever 13, guide cylinder 15, elasticity connection cord 12, limiting card 6, stop nut 14, guide peg 7, ball float 8, rigidity depression bar 9.

Wherein, the suspension cylinder 20 being connected with rigidity float lever 13 in charge for remittance hole 22 is a hollow sealing body, external diameter is less than charge for remittance bore dia, suspension cylinder 20 can freely be moved up and down charge for remittance hole 22 is interior, for example suspension cylinder 20 is the hollow circular cylinder of a sheet iron or plastic material, and its external diameter is charge for remittance hole 22(Φ 256mm) 2/3 left and right of diameter; Suspension cylinder 20 must long enoughs, and while guaranteeing that charge for remittance hole 22 internal water accumulation liquid levels raise, the suffered buoyancy of suspension cylinder 20 is greater than suspension cylinder 20 and rigidity float lever 13 is conducted oneself with dignity and the frictional resistance that is subject in up process.

Rigidity float lever 13 is a light rigidity body of rod, and material can adopt plastic conduit to make, and lower end is fixedly connected on the suspension cylinder 20 in charge for remittance hole, and upper end is connected with elasticity connection cord 12.When charge for remittance hole, 22 liquid levels rise, while reaching suspension cylinder 20 position, moved upward together by buoyancy suspension cylinder 20 and coupled rigidity float lever 13, and drive the former elasticity connection cord 12 in relaxed state to tighten gradually, and finally trigger filler block 10 and move.

Accumulation of energy case 4 sides are respectively installed a guide cylinder 15 up and down, rigidity float lever 13 is axially inserted in described guide cylinder 15, the diameter of guide cylinder 15 is a bit larger tham the diameter of rigidity float lever 13, to guarantee that rigidity float lever 13 moves freely vertically in charge for remittance hole 22, the motion of rigidity float lever 13 is not produced to too large frictional resistance again simultaneously; A stop nut 14 is installed on rigidity float lever 13 tops (being positioned at guide cylinder 15 tops), prevents too low elasticity connection cord 12 flip flop equipments that pull of its down position.

Elasticity connection cord 12 is the soft rope of scalability, and one end is connected with rigidity float lever 13 tops, and the other end is connected with filler block 10.Its effect is in the time that rigidity float lever 13 rises to certain position (water level in charge for remittance hole reaches Auto-drainage priming level 21), can open filler block 10, water in accumulation of energy case 4 is discharged and the final siphonage that triggers from gutter 19 rapidly, realize siphon drainage; Because this elastic threads has energy-storage function, open in a flash at filler block 10, the elasticity of its gathering can discharge rapidly, guarantees in 10 short time of filler block completely unlimited simultaneously.

Trigger mechanism in accumulation of energy case 4 comprises the compositions such as ball float 8, guide peg 7, rigidity depression bar 9, filler block 10, limiting card 6.Ball float 8 is the obturator that the cylindrical hole of up/down perforation has been designed in an axle center, the volume of ball float 8 depends on the buoyancy of ball float 8 in water, require the resistance producing when this power value must be greater than ball float 8, rigidity depression bar 9 is conducted oneself with dignity and ball float 8, rigidity depression bar 9 move on guide peg 7, this cylindrical hole diameter is greater than guide peg 7 diameters; Rigidity depression bar 9 is a hollow stem, is fixed on the cylindrical hole lower end of ball float 8, and its internal diameter is greater than guide peg 7 diameters.Guide peg 7 is passed to ball float 8 center cylindrical hole and rigidity depression bar 9, and be fixed on the case lid of accumulation of energy case 4, guarantee the dead in line of guide peg 7, ball float 8, rigidity depression bar 9, filler block 10, outlet pipe 11.Before automatic drain system starts, in accumulation of energy case 4, be full of water, ball float 8 and rigidity depression bar 9, under the effect of buoyancy, move on guide peg 7, and ball float 8 can arrive at accumulation of energy case case lid; In order to limit the domain of walker of ball float 8, can above accumulation of energy case 4 inner float balls 8, a limiting card 6 be set, for example limiting card 6 can be fixed on accumulation of energy case 4 medial surfaces, vertically passes limiting card 6 by guide peg 7; Limiting card also can be fixed on guide peg upper end, and is positioned at ball float 8 tops.Once touching filler block 10, elastic threads opens (, when water level in charge for remittance hole reaches Auto-drainage priming level 21), water in accumulation of energy case 4 is discharged from outlet pipe 11 fast, gutter 19 delivery ports again lead, the interior liquid level fast reducing of accumulation of energy case 4, ball float 8 declines with liquid level, when in the time that the interior water that flows to gutter 19 of accumulation of energy case 4 reaches requiring of siphonage when the height of liquid level (the head position of gutter 19 delivery ports lower than boring in), the interior liquid level of accumulation of energy case 4 is lower than ball float 8, ball float 8 loss of buoyance fall, rigidity depression bar 9 under ball float 8 is greater than the tension force of elastic threads to the design weight of lower compression filler block 10(ball float 8 and rigidity depression bar 9) close, make outlet pipe 11 upper ends in accumulation of energy case 4 airtight.Gutter 19 is identical with the diameter that inserts the interior drinking-water pipe 23 in charge for remittance hole 22, connects between the two by an one way valve 16.Once filler block 10 is closed, according to siphon principle, the water in charge for remittance hole 22 can pass through drinking-water pipe 23, one way valve 16 and gutter 19, flows out endlessly, until the position that the water level in boring exports lower than gutter 19.In order to reach above requirement, the gravity sum of the gravity of rigidity depression bar 9 and ball float 8 is less than ball float 8 suffered buoyancy in water; Suspension cylinder 20 and the gravity sum of rigidity float lever 13 are less than suspension cylinder 20 suffered buoyancy in water, in order to ensure under buoyancy ball float 8 or suspension cylinder 20 can drive rigidity depression bar 9 or rigidity float lever 13 floating.

In the time that filler block 10 is closed, owing to there being a water tank communicating pipe 17 between accumulation of energy case 4 and storage tank 3, the displacement of this water tank communicating pipe 17 be less than gutter 19 displacement (as communicating pipes 17 displacement be gutter 19 displacement 1/5), water in storage tank 3 will be full of accumulation of energy case 4, ball float 8 and rigidity depression bar 9 can raise gradually with the rising of accumulation of energy case 4 waters surface, but filler block 10 is subject to the negative pressure of bottom siphon principle generation and the acting by external hydrostatic pressure that filler block 10 upper surfaces are subject to, and filler block 10 can not be opened.

Air inlet pipe 5 is positioned at accumulation of energy case 4 casing sides, and its lower end communicates with accumulation of energy case 4 inside, and its upper end communicates with atmosphere, and can guarantee that filler block 10 is opened time, the water in accumulation of energy case 4 can be discharged from delivery port rapidly; In the time that filler block 10 is closed, the water in storage tank 3 also can flow into accumulation of energy case 4 smoothly.

Outlet pipe 11 is positioned at accumulation of energy case 4 tank floor, outlet pipe 11 calibers are the more than 3 times of Diameter of connecting pipe between storage tank 3, accumulation of energy case 4, what ensure accumulation of energy case 4 goes out water speed much larger than water intake velocity, so that the water level before siphonage is occurred in accumulation of energy case 4 can decline rapidly, for example, the internal diameter Φ 55mm of outlet pipe 11, length 30m(comprises the long 20m of pipeline that horizontal range 10m and bench face are arranged), communicating pipes 17 internal diameter be Φ 18mm.When the water yield of holding in gutter 19 reaches can realize siphonage time, ball float 8 can fall sealing accumulation of energy case 4 outlet pipes 11 in time, can be because the water in storage tank 3 enters accumulation of energy case 4 continually, cause ball float 8 cannot fall to causing the filler block 10 cannot closing phenomenon.

Filler block 10 is movably connected on outlet pipe 11 mouth of pipe places, top of accumulation of energy case 4, be that a upper surface is plane, soffit is the stopper of parabolic surface shape, when filler block 10 is during in closure state, parabola shaped curved surface and circular effluent pipe mouth coincide, similar globe valve closed structure, can seal 11 mouthfuls of outlet pipes; Due to the parabolic surface profile of filler block 10, can adapt to the slight change of 11 mouthfuls of profiles of outlet pipe; Because filler block 10 upper surfaces are horizontal plane, from the effect of hydrostatic pressure, make filler block 10 tightly block outlet pipe 11 mouths of pipe simultaneously.Along with the rising of charge for remittance hole 22 interior water levels, charge for remittance hole 22 inner suspension cylinders 20 drive rigidity float lever 13 to rise, be fixed on elasticity connection cord 12 between rigidity float lever 13 and filler block 10 stressed gradually, but due to the effect of filler block 10 deadweights and its upper surface hydrostatic pressure, filler block 10 can not move; Now the water surface in charge for remittance hole 22 continues to rise, and drive suspension cylinder 20 and rigidity float lever 13 to continue synchronous rising, the suffered tension force of elastic threads is increasing, once the suffered tension force of elastic threads exceedes the effect of filler block 10 deadweights and its upper surface hydrostatic pressure, filler block 10 can be opened thereupon, in this moment, accumulation of energy case 4 internal water accumulations flow into rapidly 11 mouthfuls of outlet pipes, when flowing water enters 11 mouthfuls of outlet pipes, can apply a jacking force upwards to the filler block 10 of parabolic surface, make filler block 10 accelerate to open; The energy being stored in elastic threads under static balancing state discharges rapidly simultaneously, and elastic threads is shunk fast, and parabola shaped stopper thoroughly backs down, and forms larger streamflow, ensures that outlet pipe 11 water outlets are smooth.

In order to facilitate the folding of filler block, filler block 10 can be realized by rotary connecting device in the flexible connection at outlet pipe 11 mouth of pipe places, as, hinge.

Storage tank 3 is cubic water tank with accumulation of energy case 4, can adopt the plastic material such as steel plate or PVC, to ensure the application life under some adverse circumstances out of doors, provide sufficient moisture in order to ensure storage tank 3 for accumulation of energy case, make the automatic drain system can continuous operation, storage tank 3 volumes are minimum be the more than 3 times of accumulation of energy case 4 volumes, for example: the long 1.2m of storage tank 3, wide 1.0m, high 1.2m; The long 0.4m of accumulation of energy case 4, wide 0.4m, high 0.6m; 3 casees heights of roofs of air inlet pipe open height and storage tank of accumulation of energy case 4 air inlet pipe 5 are consistent.

As shown in Figure 1, dewatering installation comprises drinking-water pipe 23, one way valve 16, gutter 19.

Drinking-water pipe 23 one end are connected with one way valve 16, and the other end inserts charge for remittance hole 22 internal directs to Auto-drainage lowest water level 24 places.

One way valve 16 two ends are connected with drinking-water pipe 23, gutter 19 respectively, and position, between outlet pipe 11 bottom nozzles and drinking-water pipe 23, makes the water (flow) direction in accumulation of energy case 4 only flow into gutter 19, and can not flow into drinking-water pipe 23; Gutter can be identical with the caliber of drinking-water pipe 23, as gutter 19 and the internal diameter Φ 35mm of drinking-water pipe 23.

Gutter 19 is communicated with the outlet pipe 11 lower end mouths of pipe; Gutter 19 arranges downwards along side slope, and gutter 19 delivery port levels are lower than self-draining lowest water level 24 levels, ensure charge for remittance hole 22 internal water accumulations by drainage to Auto-drainage lowest water level 24.

Specific embodiment two

In order to realize the Auto-drainage of side slope of multistage layer, can form multistage automatic drain system by the side slope automatic drain system in multiple embodiment mono-, gutter 19 outfall of the side slope automatic drain system of upper level step can be connected with the storage tank 3 of the side slope automatic drain system of next stage step, the moisture of supply the latter storage tank 3 internal consumptions, realizes the discharge downwards step by step of side slope ponding.In the second level, the storage tank 3 of (sequence from top to bottom) automatic drain system of step and the automatic drain system of lower steps at different levels thereof arranges a bleed off pipe simultaneously, guarantee that the water that upper level gutter 19 is discharged fills after this storage tank 3, flow to the final water storage place of setting by bleed off pipe.

Specific embodiment three

Fig. 4, Fig. 5, Fig. 6, Fig. 7 are the schematic diagram of side slope automatic drain system draining action.Below in conjunction with the instantiation of the on-the-spot hydrophobic application of side slope in the open of side slope automatic drain system in brief description of the drawings the present invention.

In the time that the water level in charge for remittance hole 22 reaches Auto-drainage priming level 21, the slope drainage system being placed on certain open slope step starts, and finally makes drainage system generation siphonage, and charge for remittance hole 22 ponding are drawn out of, and reach the object of automatic drainage side slope ponding.

Specific implementation process is as follows:

Step 1, system initialization.Before automatic drain system starts, in accumulation of energy case 4, be full of water, ball float 8 and rigidity depression bar 9, under the effect of buoyancy, move on guide peg 7, until ball float 8 arrives at limiting card.

Step 2, as Fig. 1, when charge for remittance hole 22 liquid levels rise, while reaching suspension cylinder 20 position, moved upward together by buoyancy suspension cylinder 20 and coupled rigidity float lever 13.Rigidity float lever 13 drives and tightens gradually in the elastic threads of relaxed state in the process moving upward, the interior continuous storage elasticity potential energy of elasticity connection cord 12, filler block 10 under its deadweight and upper surface acting by external hydrostatic pressure thereof, still 11 mouthfuls of airtight outlet pipes, now flip flop equipment as shown in Figure 4.

Step 3, in the time that the water level in charge for remittance hole 22 reaches Auto-drainage priming level 21, rigidity float lever 13 rise and by the pulling force of elasticity connection cord 12 the most at last filler block 10 open, flip flop equipment state is as shown in Figure 5.Accumulation of energy case 4 internal water accumulations flow into rapidly 11 mouthfuls of outlet pipes, now current can apply a jacking force upwards to the filler block of parabolic surface 10, make filler block 10 accelerate to open, the energy being stored in elastic threads under static balancing state discharges rapidly simultaneously, elastic threads is shunk fast, parabola shaped stopper is thoroughly opened, and water outlet forms larger discharge, and flip flop equipment state as shown in Figure 6.

After step 4, filler block 10 are opened, water flow in accumulation of energy case 4 is characterized as: water flows out accumulation of energy case 4 by outlet pipe 11, water inflow accumulation of energy case 4 in storage tank 3 carries out water supply simultaneously, but the discharge of accumulation of energy case 4 water is far longer than the water yield flowing into from storage tank 3.
