Description
Technical field
The invention belongs to geotechnical engineering field more particularly to a kind of systems of seashore slope drainage.
Background technology
China has a vast territory, and geology terrain environment is complicated, and geological disaster takes place frequently, and wherein landslide disaster lives to human being's production
Form grave danger.The generation of most of landslide disasters is related with WATER LEVEL CHANGES.The rising of level of ground water causes slip mass
Unit weight increases, and sliding surface effective stress reduces, and shearing strength reduces, and then causes landslide failure.For side slope, water level is fast before slope
When speed declines, underground water seepage flow outside slope in slope generates penetration, increases sliding force, promotes landslide failure.Therefore discharge in time
Underground water in side slope keeps stability of groundwater level, all extremely crucial to prevention landslide disaster and emergency processing.
In common slope drainage method：Horizontal gravity formula drainage efficiency is low, it is necessary to which very long drilling, uses for a long time
The problem of being present with obstruction；The construction of subdrainage hole is complicated, and quantities is big, of high cost；Sump, which draws water, needs lasting power
Source, at the same it is difficult in maintenance.Summary slope drainage method has scholar to propose siphon drainage theory, side slope siphon drainage side
There is method osculum to arrange that convenient, water-collecting capacity is strong, it is good to cut drainage effect, drillable length that is needing is small, engineering construction speed is fast
The advantages that, however in the engineering for using siphon drainage method, when running into drought season, level of ground water reduces, and slopes do not have
There is water to need to discharge by siphonage, siphon drainge system would be at stop working state, the air meeting being dissolved in the water
It is gradually precipitated in the form of bubble, air is just will continue to accumulate in siphon pipe, reduced the vacuum degree in siphon pipe, cause siphon
It is difficult to be again started up even siphonage to disappear.
The content of the invention
For in the prior art use siphon drainage method be seashore slope drainage when, because level of ground water decline siphonage
After pause, vacuum degree reduces in siphon pipe, and siphonage is difficult the defects of voluntarily recovery.Present invention offer is a kind of to utilize wave energy
Start the siphon drainge system of siphonage in real time.
The technical solution adopted by the present invention to solve the technical problems is：A kind of self set-up type side slope siphon drainge system,
It is made of vertical type dykes and dams, gas chamber, siphon pipe, exhaust pipe, blowdown pipe, check valve, side is built in the parallel coastline of vertical type dykes and dams in
Before slope, the dam crest of vertical type dykes and dams sets gas chamber, and the front end of gas chamber is buried in below seawater levels 30cm, and the one of siphon pipe
End is extend into below slope underground water bit line, and the other end of siphon pipe is extend into through gas chamber below seawater levels, exhaust pipe
One end is extend into below the phreatic line of the trailing edge of side slope, and the other end of exhaust pipe is connected with gas chamber, and blowdown pipe is arranged on gas
Check valve is all set inside room upper end, exhaust pipe and blowdown pipe.
The exhaust pipe, gas can only discharge gas chamber by check valve, and gas cannot cover gas chamber；The tonifying Qi
Pipe, gas can only cover gas chamber by check valve, it is impossible to discharge gas chamber.
When self set-up type side slope siphon drainge system works, under wave action, fierce concussion occurs for liquid level in gas chamber.
When in gas chamber
When liquid level declines, the indoor pressure of gas is lower, and blowdown pipe covers air, under the water level of the water outlet of siphon pipe
It drops, vacuum degree increases in siphon pipe, power is provided for siphonage, even if causing when slope underground water position drops to a certain range
Siphonage temporarily ceases, and when level of ground water raises again, siphonage also can voluntarily be recovered, and ensure that side slope continuously
Draining；When gas chamber liquid level raises, the indoor pressure rise of gas, the air of exhaust pipe discharge enters side slope, exhaust pipe discharge
Air enters in the trailing edge soil body of side slope, forms non-saturated region, changes the percolation path of slope underground water, and water is made to flow out slope surface,
So as to reduce the level of ground water of side slope.
1. due to the design of gas chamber of the present invention, under wave action, fierce concussion, gas chamber liquid occur for the indoor liquid level of gas
The water level of siphon pipe water outlet increases the vacuum degree in siphon pipe, is provided to siphonage dynamic also with reduction when face reduces
Power provides safeguard for the voluntarily recovery of siphonage.
2. due to the design of exhaust pipe of the present invention, after pressure raises in gas chamber, the gas of discharge enters side slope, is formed non-
Saturation region changes the percolation path of slope underground water, and water is made to flow out slope surface, achievees the effect that inflatable drainage, so as to reduce side slope
Level of ground water.
3. due to the design of blowdown pipe of the present invention, for gas room air after exhaust pipe discharge, blowdown pipe constantly carries out tonifying Qi,
Whole system is made to maintain a dynamic equilibrium, is constantly played a role.

Fig. 2 is the partial schematic diagram of the vertical type dykes and dams part of the present invention.
1 side slope, 2 vertical type dykes and dams, 3 gas chambers, 4 siphon pipes, 5 exhaust pipes, 6 blowdown pipes, 7 phreatic lines, 8 in the figure
Non-saturated region, 9 check valves.
Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments, the objects and effects of the present invention will
It is more obvious.
As shown in Figs. 1-2, a kind of self set-up type side slope siphon drainge system, by vertical type dykes and dams 2, gas chamber 3, siphon pipe 4,
Exhaust pipe 5, blowdown pipe 6, check valve 9 form, and 2 parallel coastline of vertical type dykes and dams is built in before side slope 1, vertical type dykes and dams 2
Dam crest gas chamber 3 is set, the front end of gas chamber 3 is buried in below seawater levels 30cm, and one end of siphon pipe 4 extend into side slope 1
Below phreatic line 7, the other end of siphon pipe 4 is extend into through gas chamber 3 below seawater levels, and one end of exhaust pipe 5 is stretched into
To the phreatic line below 7 of the trailing edge of side slope 1, the other end of exhaust pipe 5 is connected with gas chamber 3, and blowdown pipe 6 is arranged on gas chamber 3
Check valve 9 is all set inside upper end, exhaust pipe 5 and blowdown pipe 6.
The exhaust pipe 5, gas can only discharge gas chamber 3 by check valve 9, and gas cannot cover gas chamber 3, the benefit
Tracheae 6, gas can only cover gas chamber 3 by check valve 9, it is impossible to discharge gas chamber 3.
When self set-up type side slope siphon drainge system works, under wave action, fierce shake occurs for liquid level in gas chamber 3
It swings.When liquid level declines in gas chamber 3, the pressure in gas chamber 3 is lower, and blowdown pipe 6 covers air, the water outlet of siphon pipe 4
Water level decreasing, vacuum degree increases in siphon pipe 4, power is provided for siphonage, even if when the level of ground water of side slope 1 drops to one
Determining scope causes siphonage to temporarily cease, and when level of ground water raises again, siphonage also can voluntarily be recovered, and ensure that side slope
1 continuously draining；When 3 liquid level of gas chamber raises, the pressure rise in gas chamber 3, the air that exhaust pipe 5 is discharged enters side slope
In the 1 trailing edge soil body, non-saturated region 8 is formed, changes the percolation path of 1 underground water of side slope, water is made to flow out slope surface, so as to reduce side
The level of ground water on slope 1.
