Description
Technical field
The present invention relates to the horizontal leakage preventing composite geo-membrane such as a kind of Wall in Plain Reservoir, man-made lake, cistern or municipal landfill yard
The technology of anti-floating under the conditions of phreatic high, belongs to water conservancy, municipal administration and prevents blending anti-uplift technical field.
Background technology
As social economy is fast-developing, many Wall in Plain Reservoir, man-made lake, cistern have been built in water conservancy, municipal sector
Or municipal landfill yard etc., in these engineerings, for anti-water-stop body（Or filtrate）Seepage, Jing is often in whole reservoir bottom（Or lake
Bottom, bottom of pond, hole bottom）Laying composite geo-membrane horizontal leakage preventing system.For the horizontal leakage preventing composite earthwork of groundwater level region
Film, the subsoil water uplift pressure under the burden pressure on film is less than film（Or flatulence pressure）When, composite geo-membrane will be caused
Float（Or heave）, or even destruction is produced, cause composite geo-membrane horizontal leakage preventing disabler.Therefore, it is necessary to take effectively arrange
Apply, prevent composite geo-membrane from producing and float（Or heave）Phenomenon.
At present, prevent the horizontal leakage preventing composite geo-membranes such as Wall in Plain Reservoir, man-made lake, cistern or municipal landfill yard from floating
（Or heave）Main method have：（1）Method by earthing ballast is taken on composite geo-membrane film, makes film upward pressure all the time
More than uplift pressure under film（Or flatulence pressure）；（2）When under film, uplift pressure is higher than burden pressure on film, by arrange non-return valve or
Special water supply valve is opened, subsoil water is introduced in storehouse（Or in lake, in pond, in hole）, make on film uplift under burden pressure and film
Power keeps balance；（3）Chinese invention patent ZL 201010011435.8 " a kind of method for laying anti-seepage geomembrane " is described and is passed through
Gas extraction system under laying film, the method that geomembrane inflatable is eliminated using vacuum pumping method.
All there is certain defect in said method：Method 1 arranges ballast soil on film, occupies reservoir, man-made lake, cistern
Or the volume of municipal landfill yard；Method 2 can cause some subsoil water inferior to enter in reservoir, man-made lake, cistern, affect water-retention
Water quality；Method 3 is only capable of solving the problems, such as flatulence and can not eliminating uplift pressure and float, and consumes energy, and increases operational and administrative expenses.
The content of the invention
To solve above-mentioned bottleneck problem, the invention provides one kind can be used for Wall in Plain Reservoir, man-made lake, cistern or municipal administration
Novel composite geo-membrane anchoring float Structure in the composite geo-membrane horizontal leakage preventing engineering such as landfill yard, the structure have anti-uplift
Power floats（Or anti-flatulence is heaved）Ability, without damage impermeable composite geomembrane function, and have easy construction, low cost
The advantages of honest and clean, effect is good.
The technical solution adopted for the present invention to solve the technical problems is：
The horizontal leakage preventing composite geo-membrane anchoring float Structure includes anti-floating composite geo-membrane, native anchor and anchor structure.Its feature
It is：
Described anti-floating composite geo-membrane is, in composite geo-membrane production process, to adopt non-woven geotextile in the one side of film,
Another side connects composite geo-membrane and anchor structure using suspender belt using the Woven geofabric for having suspender belt, spins geotechnique using having
Cloth undertakes and disperses anchor pole concentration power, to strengthen the ability that anti-floating composite geo-membrane resists uplift pressure；Described has having for suspender belt
Geotextiles are spun, woven geotextile or braided geotextile can be adopted, wherein suspender belt is high-strength material, suspender belt can be given birth in Woven geofabric
Woven into during product, and along the warp-wise of Woven geofabric（Longitudinal direction）It is evenly arranged, suspender belt spacing is floating according to undertaking
The type of the size and anchor structure of power determines；Described native anchor is exactly common anchor pole, will by jumbolter and Anchor Agent
Anchor pole is fixed in foundation soil；Described anchor structure refers to the attachment structure of anchor pole and anti-floating composite geo-membrane, multiple by anti-floating
The suspender belt closed on geomembrane can pass through to be to connect or weld realization with the connection of high-strength material suspender belt preset on anchor structure, also may be used
Using other connected modes, general wired anchor and point two kinds of anchor structures of anchor；Described line anchor anchor structure refers to and is combined anti-floating
Geomembrane is fixed on concrete beam（Or girder steel, plastic beam）On, and concrete beam（Or girder steel, plastic beam）Fixed by anchor pole；Described point
Anchor anchor structure refers to and for anti-floating composite geo-membrane to be directly fixed on Round Concrete block（Or circular steel plate, round plastic plate）On, it is circular
Concrete block（Or circular steel plate, round plastic plate）Fixed by anchor pole.
Contrast prior art, the beneficial effects of the present invention is：
The principle and mounting structure of the present invention is simple, the floating caused by ego resistance subsoil water uplift pressure by native anchor or gas
It is swollen cause heave.Compared with ballast soil anti-floating is set on the film with method 1, the present invention be not take up reservoir, man-made lake, cistern or
The volume of municipal landfill yard；Subsoil water is supplemented in storehouse with method 2, compared by water weight anti-floating on film, the present invention is not interfered with
The water quality of stored water in reservoir, man-made lake, cistern；Compared with 3 vacuum pumping method of method, the present invention being capable of anti-floating and saving
The energy；Compared with native anchor connection composite geo-membrane is directly used, this method can avoid composite geo-membrane local from drawing badly or seep water.
The present invention's is mainly characterized by：
（1）Composite geo-membrane adopts the one side of anti-floating composite geo-membrane, anti-floating composite geo-membrane to adopt common non-woven fabrics, separately
One side is the Woven geofabric for having suspender belt, and suspender belt is high-strength material suspender belt, can undertake the concentration power or line load of native anchor, and
Power is disperseed, it is to avoid geomembrane produces tensile failure or produces the excessive deformation in local.
（2）Using the restraining forceies opposing subsoil water uplift pressure or flatulence pressure of native anchor.
（3）Anti-floating composite geo-membrane is coupled together with native anchor by line anchor or point anchor anchor structure, make anti-floating composite earth
Work film has anti-floating and anti-flatulence ability.
Therefore, the invention provides one kind can be used for the composite earths such as Wall in Plain Reservoir, man-made lake, cistern or municipal landfill yard
New anti-floating composite geo-membrane anchoring float Structure in the flat seepage control project of work film water, lives anti-floating composite earthwork using native anchor anchor
Film, solves the problems, such as that composite geo-membrane is floated by subsoil water uplift pressure or flatulence heaves destruction, is that composite geo-membrane level is prevented
Ooze structural anti-buoyancy（Subsoil water uplift pressure）Or anti-drum（Flatulence）There is provided a kind of new method.
