Description
Technical field
The invention belongs to Geotechnical Engineering field, more particularly to a kind of seashore and the device of reservoir stability draining.
Background technology
China is vast in territory, and geology terrain environment is complicated, and geological disaster takes place frequently, and wherein landslide disaster is lived to human being's production
Constitute grave danger.The generation of most of landslide disasters is relevant with WATER LEVEL CHANGES.The rising of level of ground water causes slip mass
Unit weight increases, the reduction of sliding surface effective stress, and shearing strength reduces, and then causes landslide failure.For reservoir stability, as slope Qian Shui
During the rapid decrease of position, underground water produces penetration to seepage flow outside slope in slope, increases sliding force, promotes landslide failure.Therefore in time
Underground water in discharge side slope, keeps level of ground water to be in a relatively low level, can effectively prevent the generation on landslide.
In conventional slope drainage method:Horizontal drainage channel efficiency is low, and hole position selection is difficult, and long-time stability are poor, easily
There is obstruction and cause failure;Though subdrainage hole drainage effect is good, its construction is relative complex, and quantities is big, high cost;
Sump draws water needs lasting power source, while difficult in maintenance.Summary slope drainage method, has scholar to propose siphon
There is water discharge technology, side slope siphon drainage method osculum to arrange that convenient, water-collecting capacity is strong, cut the brill that drainage effect is good, need
The advantages of hole length is small, engineering construction speed is fast, but in the engineering using siphon drainage method, run into drought season
When, level of ground water reduction, siphon drainge system can temporarily in the state that is stopped, because the air being dissolved in the water can be with gas
The form of bubble is gradually separated out, in siphon pipe will continuous accumulation air, reduce the vacuum in siphon pipe, be such as in for a long time
Arrhea state, siphon drainage can be caused to restart difficult even siphon and interrupted.
The content of the invention
During in the prior art using siphon drainage method for seashore and reservoir stability draining, make because level of ground water declines siphon
After pause, vacuum reduction in siphon pipe, siphonage is difficult the defect voluntarily recovered.The present invention provides one kind and utilizes wave
The siphon drainage device of siphonage can in real time be started.
The technical solution adopted for the present invention to solve the technical problems is:It is a kind of to aid in slope drainage using hollow floating body
Device, is made up of hollow floating body, anchor cable, air chamber, siphon pipe, blast 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 chamber forms air chamber, one end of siphon pipe
It extend into below slope underground water bit line, the other end of siphon pipe is extend into below seawater levels through air chamber, the one of blast pipe
End is extend into below the phreatic line of the trailing edge of side slope, and the other end of blast pipe is connected with air chamber, and blowdown pipe is arranged on air chamber
Check valve is all set inside upper end, blast pipe and blowdown pipe.
Further, described hollow floating body submerges below seawater levels 30cm.
Further, described blast pipe, gas can only discharge air chamber by check valve, and gas can not cover air chamber, institute
The blowdown pipe stated, gas can only cover air chamber by check valve, it is impossible to discharge air chamber.
When a kind of device using hollow floating body auxiliary slope drainage works, under wave action, liquid level hair in air chamber
Raw fierce concussion.When liquid level declines in air chamber, the pressure step-down in air chamber, blowdown pipe covers air, the delivery port of siphon pipe
The water level decreasing at place, vacuum increases in siphon pipe, for siphonage provides power, even if when the level of ground water of side slope drops to
Certain limit causes siphonage to temporarily cease, and when level of ground water is raised again, siphonage also can voluntarily be recovered, it is ensured that side
Slope continuously draining;When air chamber liquid level is raised, the pressure in air chamber is raised, and the air of blast pipe discharge enters side slope
In the trailing edge soil body, non-saturated region is formed, change the percolation path of slope underground water, flow out water domatic, so as to reduce side slope
Level of ground water.
Advantages of the present invention is as follows.
1., due to the design of air chamber of the present invention, under wave action, there is fierce concussion, air chamber liquid in the liquid level in air chamber
The water level of siphon pipe water outlet increases the vacuum in siphon pipe also with reduction when face reduces, and provides dynamic to siphonage
Power, is that the voluntarily recovery of siphonage provides safeguard.
2., due to the design of blast pipe of the present invention, after pressure is raised in air chamber, the gas of discharge enters side slope, is formed non-
Saturation region, changes the percolation path of slope underground water, flows out water domatic, the effect of inflatable drainage is reached, so as to reduce side slope
Level of ground water.
3., due to the design of blowdown pipe of the present invention, from after blast pipe discharge, blowdown pipe constantly carries out tonifying Qi to gas room air,
Whole system is maintained a dynamic equilibrium, constantly play a role.
4. of the invention to converge wave energy using hollow floating body, it is built is not influenceed by ground and the depth of water;Build fast
Speed, it is easy to remove, and cost is smaller by water depth effect, while being applied to seashore side slope and reservoir stability.
