Isingeniso esifushane senqubo yokukhiqiza, izici, izidingo zokubeka kanye nokushisela ze-geomembrane eyinhlanganisela

I-geomembrane eyinhlanganisela ishisiswe yi-infrared ekude kuhhavini ohlangothini olulodwa noma izinhlangothi zombili zolwelwesi, futhi i-geotextile ne-geomembrane zicindezelwa ndawonye ngerola eliqondisayo ukuze kwakheke i-geomembrane eyinhlanganisela.Kukhona nenqubo yokusakaza i-geomembrane eyinhlanganisela.Ifomu layo liyindwangu eyodwa nefilimu eyodwa, izindwangu ezimbili nefilimu eyodwa, amafilimu amabili nendwangu eyodwa, izindwangu ezintathu namafilimu amabili, njll.

Izici

I-geotextile isetshenziswa njengongqimba oluvikelayo lwe-geomembrane ukuze kuvikelwe ungqimba olungagxumeki ekulimaleni.Ukuze unciphise imisebe ye-ultraviolet futhi ukwandise ukumelana nokuguga, indlela yokungcwatshwa isetshenziselwa ukubeka.

1. Ububanzi obungamamitha angu-2, amamitha angu-3, ​​amamitha angu-4, amamitha angu-6 namamitha angu-8 yibo obusebenza kakhulu;

2. High ukubhoboza ukumelana kanye high friction coefficient;

3. Ukumelana nokuguga okuhle, ukuzivumelanisa nezinga lokushisa elihlukahlukene elizungezile;

4. Ukusebenza okuhle kakhulu kwe-anti-drainage;

5. Isebenza endaweni yokongiwa kwamanzi, amakhemikhali, ezokwakha, ezokuthutha, indlela ehamba ngaphansi, umhubhe, ukulahlwa kukadoti namanye amaphrojekthi.

Ukucutshungulwa kwe-Grassroots

1) Isendlalelo sesisekelo lapho i-geomembrane eyinhlanganisela ebekwe khona kufanele ibe isicaba, futhi umehluko wobude bendawo akufanele ube mkhulu kuno-50mm.Susa izimpande zesihlahla, izimpande zotshani kanye nezinto eziqinile ukuze ugweme ukulimala kwe-geomembrane eyinhlanganisela.

Ukubekwa kwezinto ezihlanganisiwe ze-geomembrane

1) Okokuqala, hlola ukuthi impahla yonakele noma cha.

I-2) I-geomembrane ehlanganisiwe kufanele ibekwe ngokuvumelana nesiqondiso samandla ayo amakhulu, futhi ngesikhathi esifanayo, akufanele idonswe ngokuqinile, futhi inani elithile lokunwetshwa nokufinyela kufanele ligcinwe ukuze livumelane nokuguqulwa kwe-matrix..

3) Uma ubeka, kufanele uqiniswe ngesandla, ngaphandle kwemibimbi, futhi usondelene nongqimba oluphansi lokuthwala.Kufanele ihlanganiswe noma nini nesitolo ukugwema ukuphakanyiswa umoya.Ukwakhiwa akukwazi ukwenziwa lapho kunamanzi amile noma imvula, futhi i-bentonite mat ebekwe ngosuku kufanele ihlanganiswe ne-backfill.

4) Lapho i-geomembrane eyinhlanganisela ibekwa, kufanele kube khona umkhawulo emikhawulweni yomibili.Imajini akumele ibe ngaphansi kuka-1000mm ekugcineni ngakunye, futhi izolungiswa ngokuvumelana nezidingo zokuklama.

5) Ububanzi obuthile befilimu ye-PE nendwangu ye-PET ungqimba olunganamatheli (okungukuthi, ukwenqatshwa komphetho) kugcinwe ezinhlangothini zombili ze-geomembrane eyinhlanganisela.Lapho ubeka, isiqondiso seyunithi ngayinye ye-geomembrane eyinhlanganisela kufanele ilungiswe ukuze kube lula amayunithi amabili we-geomembrane eyinhlanganisela.ukushisela.

6) Ku-geomembrane ehlanganisiwe ehlanganisiwe, akufanele kube khona amafutha, amanzi, uthuli, njll.

7) Ngaphambi kokushisela, lungisa ifilimu eyodwa ye-PE ezinhlangothini ezimbili zomthungo ukuze ihambisane nobubanzi obuthile.Ububanzi bokugqagqana ngokuvamile bungu-6-8cm futhi buyisicaba futhi asinamibimbi emhlophe.

Ukushisela;

I-geomembrane eyinhlanganisela ishiselwe kusetshenziswa umshini wokushisela we-track-track, futhi ingaphezulu lefilimu ye-PE exhunywe ukwelashwa kokushisa iyashiswa ukuze incibilike phezulu, bese ihlanganiswa emzimbeni owodwa ngengcindezi.

1) Welding bead ethangeni ububanzi: 80 ~ 100mm;ukugoqa kwemvelo endizeni kanye nendiza eqondile: 5% ~ 8% ngokulandelana;ukunwetshwa okugodliwe kanye nenani lokufinyela: 3%~5%;izinsalela ezisele: 2% ~ 5%.

2) Izinga lokushisa elisebenzayo le-hot melt welding lingu-280 ~ 300 ℃;ijubane lokuhamba ngu-2 ~ 3m/min;ifomu lokushisela liyi-double-track welding.

I-3) Indlela yokulungisa izingxenye ezilimele, izinto zokusika ezinezincazelo ezifanayo, ukubopha okushisayo okuncibilikayo noma ukufakwa uphawu ngeglue ekhethekile ye-geomembrane.

4) Ukuze kuxhunywe izindwangu ezingezona ezilukiwe ku-weld bead, inhlanganisela ye-geotextile ezinhlangothini zombili zolwelwesi ingashiselwa ngesibhamu esishisela umoya oshisayo uma ingaphansi kwe-150g/m2, futhi umshini wokuthunga ophathwayo ungasetshenziswa. ukuthunga ngaphezu kuka-150g/m2.

5) Indawo yokuvala nokumisa amanzi yomlomo ongaphansi kwamanzi kufanele ivalwe ngomugqa wokumisa amanzi werabha we-GB, usongwe ngensimbi futhi uphathwe nge-anti-corrosion.

Gcwalisa emuva

1. Uma ugcwalisa emuva, isivinini sokugcwalisa kufanele silawulwe ngokuya ngezidingo zokuklama kanye nokuxazululwa kwesisekelo.

2. Ngesendlalelo sokuqala sokugcwaliswa kwenhlabathi ezintweni ze-geosynthetic, umshini wokugcwalisa ungagijima kuphela uhambisane nesiqondiso se-perpendicular ukuya ekubekweni kwezinto ezibonakalayo ze-geosynthetic, kanye nemishini yokukhanya (ingcindezi engaphansi kuka-55kPa) kufanele isetshenziselwe ukusabalalisa noma ukuginqika.
