Description
Technical field
The invention belongs to geotechnical engineering, coastal engineering field more particularly to a kind of devices of auxiliary 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
Constitute 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 side slope, water level is fast before slope
When speed declines, underground water seepage flow to 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, needs the drilling grown very much, uses for a long time
The problem of will appear 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.In 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 using siphon drainage method, when encountering drought season, level of ground water reduces, and slopes do not have
There is water to need to be discharged 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, so that the vacuum degree in siphon pipe is reduced, lead to siphon
It is difficult to be again started up even siphonage to disappear.
Invention content
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 defect voluntarily restored.Present invention offer is a kind of to utilize wave energy
Start 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 be arranged using Semi -- circular Breakwater auxiliary side slope
The device of water, by Semi -- circular Breakwater, catch can room, siphon pipe form, Semi -- circular Breakwater arrangement form is jetty, semi-circular anti-
The center of wave dike is equipped with partition wall, the laid inside back-up sand of Semi -- circular Breakwater, and the back of the body wave side of Semi -- circular Breakwater, which is equipped with, catches energy room,
The rear wall for catching energy room stretches into seawater face hereinafter, the antetheca for catching energy room is equipped with hole, and one end of siphon pipe extend into slope underground water
Bit line is hereinafter, the other end of siphon pipe passes through the rear wall for catching energy room to extend into seawater levels or less.
Further, the rear wall for catching energy room is buried in seawater levels 30cm or less.
Further, the levee body of the Semi -- circular Breakwater is precast reinforced mixed to be made of semicircular arch ring and bottom plate
Solidifying soil component.
When wave arrives, wave will produce more unrestrained after hitting the side of heading sea of Semi -- circular Breakwater, and cross Semi -- circular Breakwater
Hole of the wave at top by catching energy room antetheca is caught the indoor liquid level generation fierceness of energy and is shaken into energy room is caught.It can room catching
When interior liquid level drastically declines, the water level decreasing of the water outlet of siphon pipe, vacuum degree increases in siphon pipe, is provided for siphonage
Power, even if causing siphonage to temporarily cease when slope underground water position drops to a certain range, when level of ground water increases again,
Siphonage also can voluntarily be restored, and ensure that side slope continuously drains.
Advantages of the present invention is as follows.
1. since the present invention catches the design of energy room, in more unrestrained generation, catches the indoor liquid level of energy and fierce concussion occurs, catching
When energy room liquid level reduces, the water level of siphon pipe water outlet increases the vacuum degree in siphon pipe, gives siphonage also with reduction
Power is provided, is provided safeguard for the voluntarily recovery of siphonage.
2. due to Semi -- circular Breakwater levee body be arch, act on levee body head sea side wave force be directed toward the center of circle, generate
Horizontal direction wave force it is smaller, vertically to action of wave force in the side of heading sea of levee body, it is small that tilting moment generated to levee body, but be easy
Generate more unrestrained, waters in dike steadily impacted, the present invention using catches can room dissipate more unrestrained this portion of energy, and by this portion
Energy is divided to be converted into the power for starting siphon drainage.
3. the foundation stress of Semi -- circular Breakwater lightweight construction, generation is small, it is weakness to be particularly suitable for littoral zone ground
Soil base.
Description of the drawings
Fig. 1 is overall structure of the present invention.
Fig. 2 is the partial schematic diagram of the Semi -- circular Breakwater part of the present invention.
Energy room, 4 siphon pipes, 5 phreatic lines, 6 partition walls, 7 back-up sands are caught in 1 side slope, 2 Semi -- circular Breakwaters, 3 in the figure.
Specific implementation mode
Invention is further described in detail in the following with reference to the drawings and specific embodiments, and the objects and effects of the present invention will
It is more obvious.
As shown in Figs. 1-2, a kind of device being assisted slope drainage using Semi -- circular Breakwater, by Semi -- circular Breakwater 2, is caught
Energy room 3, siphon pipe 4 form, and 2 arrangement form of Semi -- circular Breakwater is jetty, and the center of Semi -- circular Breakwater 2 is equipped with partition wall 6, partly
The laid inside back-up sand 7 of round breakwater 2, the back of the body wave side of Semi -- circular Breakwater 2, which is equipped with, catches energy room 3, and the rear wall for catching energy room 3 stretches into
Hereinafter, the antetheca for catching energy room 3 is equipped with hole, one end of siphon pipe 4 extend into the phreatic line 5 of side slope 1 hereinafter, rainbow in seawater face
The other end of suction pipe 4 passes through the rear wall for catching energy room 3 to extend into seawater levels or less.
Further, the rear wall for catching energy room 3 is buried in seawater levels 30cm or less.
Further, the levee body of the Semi -- circular Breakwater 2 is precast reinforced to be made of semicircular arch ring and bottom plate
Concrete component.
When wave arrives, wave will produce more unrestrained after hitting the side of heading sea of Semi -- circular Breakwater 2, and cross Semi -- circular Breakwater
Hole of the wave by catching 3 antetheca of energy room at the top of 2 into energy room 3 is caught, shake by the liquid level generation fierceness caught in energy room 3.It is catching
Can be when liquid level drastically decline in room 3, the water level decreasing of the water outlet of siphon pipe 4, vacuum degree increases in siphon pipe 4, is siphon
Effect provides power, even if causing siphonage to temporarily cease when 1 level of ground water of side slope drops to a certain range, level of ground water is again
When secondary raising, siphonage also can voluntarily be restored, and ensure that side slope 1 continuously drains.
