Description
Technical field
The invention belongs to geotechnical engineering field more particularly to a kind of seashores and the device of reservoir stability draining.
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 leads to slip mass
Unit weight increases, and sliding surface effective stress reduces, and shearing strength reduces, and then leads to landslide failure.For reservoir stability, as slope Qian Shui
During the rapid decrease of position, underground water seepage flow outside slope in slope generates penetration, increases sliding force, promote landslide failure.Therefore in time
The underground water in side slope is discharged, level of ground water is kept to be in a relatively low level, the generation on landslide can be effectively prevent.
In common slope drainage method：Horizontal drainage channel efficiency is low, and the selection of hole position is difficult, and long-time stability are poor, easily
Appearance blocks and causes to fail；Though subdrainage hole drainage effect is good, its construction is relative complex, and quantities is big, of high cost；
Sump, which draws water, needs lasting power source, while difficult in maintenance.Summary slope drainage method, has scholar to propose siphon
Water discharge technology, side slope siphon drainage method have the brill that osculum arrangement is convenient, water-collecting capacity is strong, section drainage effect is good, needs
The advantages that hole length is small, engineering construction speed is fast, however in the engineering for using siphon drainage method, encounter drought season
When, level of ground water reduces, and siphon drainge system can temporarily be in stop working state, since the air being dissolved in the water can be with gas
The form of bubble is gradually precipitated, and air is just will continue to accumulate in siphon pipe, reduces the vacuum degree in siphon pipe, as being in for a long time
Arrhea state, siphon drainage can be caused to restart difficult even siphon and interrupted.
Invention content
During for using siphon drainage method as seashore and reservoir stability draining in the prior art, because level of ground water declines rainbow
After suction effect pause, vacuum degree reduces in siphon pipe, and siphonage is difficult the defects of voluntarily recovery.The present invention provides a kind of utilization
Wave energy starts the siphon drainage device of siphonage in real time.
The technical solution adopted by the present invention to solve the technical problems is：It is a kind of to assist slope drainage using hollow floating body
Device is made of hollow floating body, anchor cable, gas chamber, siphon pipe, exhaust pipe, blowdown pipe, check valve, and hollow floating body is upside down in side slope
The front water surface on, hollow floating body bottom is connected by anchor cable with ground, and hollow floating body inner cavity forms gas chamber, one end of siphon pipe
Extend into slope underground water bit line hereinafter, siphon pipe the other end pass through gas chamber extend into seawater levels hereinafter, exhaust pipe one
End extend into the phreatic line of the rear of side slope hereinafter, the other end of exhaust pipe is connected with gas chamber, and blowdown pipe is arranged on gas chamber
Check valve is all set inside upper end, exhaust pipe and blowdown pipe.
Further, the hollow floating body is submerged below seawater levels 30cm.
Further, the exhaust pipe, gas can only discharge gas chamber by check valve, and gas cannot cover gas chamber, institute
The blowdown pipe stated, gas can only cover gas chamber by check valve, it is impossible to discharge gas chamber.
When a kind of device using hollow floating body auxiliary slope drainage works, under wave action, liquid level is sent out in gas chamber
Raw fierce concussion.When liquid level declines in gas chamber, the indoor pressure of gas is lower, and blowdown pipe covers air, the water outlet of siphon pipe
The water level decreasing at place, vacuum degree increases in siphon pipe, power is provided for siphonage, even if the level of ground water when side slope drops to
A certain range causes siphonage to temporarily cease, and when level of ground water increases again, siphonage also can voluntarily be restored, and ensure that side
Slope continuously draining；When gas chamber liquid level increases, the indoor pressure raising of gas, the air of exhaust pipe discharge enters side slope
In the rear soil body, non-saturated region is formed, changes the percolation path of slope underground water, water is made to flow out slope surface, so as to reduce side slope
Level of ground water.
Advantages of the present invention is as follows.
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, the voluntarily recovery for siphonage provide safeguard.
2. due to the design of exhaust pipe of the present invention, in gas chamber after pressure raising, 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.
4. the present invention's converges wave energy using hollow floating body, build is not influenced by ground and the depth of water；It builds fast
Speed, it is easy to remove, and cost is smaller by water depth effect, while suitable for seashore side slope and reservoir stability.
