Cov kev cai lij choj rau kev kho qhov chaw geomembrane yog dab tsi?

Geomembrane anchorage muab faib ua kab rov tav anchorage thiab ntsug anchorage. Ib qho anchorage trench raug khawb hauv txoj kev nees kab rov tav, thiab qhov dav hauv qab trench yog 1.0 m, Groove tob 1.0 m, Cast-in-place concrete lossis backfill anchorage tom qab tso geomembrane, cross-section 1.0 mx1.0 m, Qhov tob yog 1 m.

Cov kev cai tshwj xeeb rau kev kho qhov chaw geomembrane feem ntau suav nrog cov hauv qab no:‌:

1. ​Kev teeb tsa kab ke thiab txoj kev‌:

• Lub geomembrane yuav tsum tau manually muab tso rau hauv cov ntu thiab cov blocks raws li qhov kev txiav txim ntawm thawj zaug upstream thiab tom qab ntawd downstream, thawj qhov nqes hav thiab tom qab ntawd groove hauv qab.
• Thaum tso, lub geomembrane yuav tsum tau so kom zoo, khaws cia 3% ~ 5% Qhov seem seem yog ua rau hauv hom kev so kom zoo li nthwv dej ntawm qhov tawm los hloov kho rau qhov hloov pauv ntawm qhov kub thiab qhov av qis ntawm lub hauv paus, thiab zam kev puas tsuaj rau cov khoom siv dag.
• Thaum tso cov geomembrane sib xyaw rau ntawm qhov chaw nqes hav, qhov kev teeb tsa ntawm cov pob qij txha yuav tsum sib luag lossis ntsug rau kab nqes hav loj, thiab yuav tsum tau muab tso rau hauv qhov kev txiav txim los ntawm sab saud mus rau hauv qab.
• 

• ​Txoj kev kho kom ruaj khov‌:

• ​Kev kho qhov anchor grooveHauv qhov chaw tsim kho, feem ntau siv cov trench anchorage. Raws li cov xwm txheej siv thiab cov xwm txheej kev ntxhov siab ntawm cov geomembrane tiv thaiv seepage, khawb lub trench anchoring nrog qhov dav thiab qhov tob tsim nyog, thiab qhov dav feem ntau yog 0.5 m-1.0 m, qhov tob yog 0.5 m-1m. Cov geomembrane tiv thaiv seepage raug tso rau hauv qhov anchoring ditch thiab cov av backfill raug compacted, thiab cov nyhuv kho zoo dua.

• ​Kev ceev faj txog kev tsim kho‌:

• Ua ntej tso geomembrane, ntxuav lub hauv paus kom paub tseeb tias lub hauv paus huv thiab tsis muaj cov khoom ntse, thiab ua kom lub pas dej ntawm lub pas dej tiaj tus raws li qhov yuav tsum tau tsim.
• Cov txheej txheem txuas geomembrane feem ntau suav nrog txoj kev vuam thermal thiab txoj kev sib txuas. Txoj kev vuam thermal yog qhov tsim nyog rau PE Composite geomembrane, txoj kev sib txuas feem ntau siv rau hauv zaj duab xis yas thiab cov khoom siv mos mos lossis RmPVC Kev Sib Txuas ntawm.
• Thaum lub sijhawm tso geomembrane, txheej cushion sab saud thiab txheej tiv thaiv rov qab, txhua yam khoom ntse yuav tsum tsis txhob kov lossis cuam tshuam rau geomembrane kom tiv thaiv geomembrane kom tsis txhob raug punctured.

Los ntawm cov kev cai saum toj no thiab cov txheej txheem kev tsim kho, qhov geomembrane nqes hav tuaj yeem kho tau zoo kom ntseeg tau tias nws ruaj khov thiab tiv thaiv kev seepage thaum siv.
