Intshayelelo emfutshane kwinkqubo yokuvelisa, iimpawu, ukubeka kunye neemfuno ze-welding ye-geomembrane edibeneyo

I-geomembrane edibeneyo ifudunyezwa yi-infrared kude kwi-oven kwelinye icala okanye macala omabini e-membrane, kwaye i-geotextile kunye ne-geomembrane zixinzelelwe kunye ne-roller yesikhokelo ukwenza i-geomembrane edibeneyo.Kukwakho nenkqubo yokuphosa i-geomembrane edibeneyo.Ifom yayo yengubo enye kunye nefilimu enye, iingubo ezimbini kunye nefilimu enye, iifilimu ezimbini kunye nengubo enye, iingubo ezintathu kunye neefilimu ezimbini, njl.

Iimbonakalo

I-geotextile isetyenziswa njengomaleko okhuselayo we-geomembrane ukukhusela umaleko ongagungqiyo kumonakalo.Ukuze kuncitshiswe imisebe ye-ultraviolet kunye nokwandisa ukumelana nokuguga, indlela yokungcwaba isetyenziselwa ukubeka.

1. Ububanzi beemitha ezi-2, iimitha ezi-3, iimitha ezi-4, iimitha ezi-6 kunye ne-8 yeemitha zezona zisebenzayo;

2. Ukuxhathisa okuphezulu kwe-puncture kunye ne-coefficient ephezulu ye-friction;

3. Ukumelana nokuguga okulungileyo, ukulungelelanisa uluhlu olubanzi lobushushu be-ambient;

4. Ukusebenza okugqwesileyo kokuchasana nokukhupha amanzi;

5. Isebenza kugcino lwamanzi, imichiza, ulwakhiwo, uthutho, umzila ongaphantsi komhlaba, itonela, ukulahlwa kwenkunkuma kunye nezinye iiprojekthi.

Ukusetyenzwa kweGrassroots

I-1) Uluhlu lwesiseko apho i-geomembrane edibeneyo ibekwe khona kufuneka ibe tyaba, kwaye umehluko wokuphakama kwendawo akufanele ube mkhulu kune-50mm.Susa iingcambu zomthi, iingcambu zengca kunye nezinto ezinzima ukuphepha umonakalo kwi-geomembrane edibeneyo.

Ukubekwa kwezinto ezidibeneyo ze-geomembrane

1) Okokuqala, khangela ukuba izinto zonakaliswe okanye cha.

I-2) I-geomembrane edibeneyo kufuneka ibekwe ngokwesikhokelo sayo esiphambili samandla, kwaye ngelo xesha, akufanele itsalwe ngokuqinileyo, kwaye inani elithile lokwandiswa kunye nokunciphisa kufuneka ligcinwe ukulungelelanisa ukuguqulwa kwe-matrix..

3) Xa ubeka, kufuneka uqiniswe ngesandla, ngaphandle kwemibimbi, kwaye usondele kwinqanaba eliphantsi lokuthwala.Kufuneka idityaniswe nangaliphi na ixesha kunye nevenkile ukuphepha ukuphakanyiswa ngumoya.Ukwakhiwa akukwazi ukuphunyezwa xa kukho amanzi amileyo okanye imvula, kwaye i-bentonite mat ebekwe ngosuku kufuneka ihlanganiswe ne-backfill.

4) Xa i-geomembrane edibeneyo ibekwe, kufuneka kubekho umda kuzo zombini iziphelo.Umda awuyi kuba ngaphantsi kwe-1000mm kwisiphelo ngasinye, kwaye uya kulungiswa ngokweemfuno zoyilo.

I-5) Ububanzi obuthile befilimu ye-PE kunye ne-PET fabric layer non-adhesive layer (oko kukuthi, ukugatywa komphetho) kugcinwe kumacala omabini e-geomembrane edibeneyo.Xa ubeka, isalathiso seyunithi nganye ye-geomembrane edibeneyo kufuneka ilungiswe ukuze iququzelele iiyunithi ezimbini ze-geomembrane edibeneyo.ukuwelda.

6) Kwi-geomembrane edibeneyo edibeneyo, akufanele kubekho ioli, amanzi, uthuli, njl.

I-7) Ngaphambi kwe-welding, lungisa ifilimu enye ye-PE kumacala amabini omthungo ukuze idibanise ububanzi obuthile.Ububanzi be-overlap buba yi-6-8cm kwaye icaba kwaye ayinamibimbi emhlophe.

Ukuwelda;

I-geomembrane ehlanganisiweyo idityaniswe kusetyenziswa umatshini we-welding we-double-track, kwaye umphezulu wefilimu ye-PE edityaniswe ngonyango lobushushu ishushu ukuze inyibilike umphezulu, ize idityaniswe kumzimba omnye ngoxinzelelo.

1) Welding bead lap ububanzi: 80 ~ 100mm;ukugoba kwendalo kwinqwelomoya nakwinqwelomoya ethe nkqo: 5% ~ 8% ngokulandelanayo;Ulwandiso olubekelwe bucala kunye nexabiso lokucutha: 3%~5%;inkunkuma eshiyekileyo: 2% ~5%.

2) Ubushushu obusebenzayo be-welding eshushu yi-280 ~ 300 ℃;isantya sokuhamba yi-2 ~ 3m/min;ifom ye-welding i-double-track welding.

3) Indlela yokulungisa iindawo ezonakalisiweyo, izinto zokusika ezineenkcukacha ezifanayo, ukudibanisa okutshisa okutshisayo okanye ukutywinwa ngeglue ekhethekileyo ye-geomembrane.

4) Ukudibanisa amalaphu angalukwanga kwi-weld bead, i-geotextile composite kumacala omabini e-membrane inokudityaniswa kunye nompu we-welding womoya oshushu ukuba ungaphantsi kwe-150g / m2, kwaye umatshini wokuthunga ophathwayo unokusetyenziselwa. ukuthunga ngaphezulu kwe-150g/m2.

5) Ukutywinwa kunye nokumisa amanzi kwi-nozzle engaphantsi kwamanzi kuya kutywinwa nge-GB ye-rubber yokumisa amanzi, ehlanganiswe ngesinyithi kwaye iphathwe nge-anti-corrosion.

Ukuzaliswa ngasemva

1. Xa u-backfilling, isantya sokubuyisela kufuneka silawulwe ngokweemfuno zoyilo kunye nokuhlaliswa kwesiseko.

2. Ngomaleko wokuqala wokuzaliswa komhlaba kwizinto ze-geosynthetic, umatshini wokuzalisa unokuhamba kuphela kwicala le-perpendicular ukuya kwindlela yokubeka izinto ze-geosynthetic, kunye noomatshini bokukhanya (uxinzelelo olungaphantsi kwe-55kPa) kufuneka lusetyenziswe ukusabalalisa okanye ukuqengqeleka.
