Geosynthetics nijambo rusange kubikoresho byubukorikori bikoreshwa mubwubatsi. Nkibikoresho byubwubatsi bwa gisivili, ikoresha polimeri yubukorikori (nka plastiki, fibre chimique, reberi yubukorikori, nibindi) nkibikoresho fatizo kugirango ikore ibicuruzwa bitandukanye, bishyirwa mubutaka, hejuru cyangwa hagati yubutaka butandukanye. , kugira uruhare mu kurinda amazi no kurwanya amazi, gushimangira, kuvoma no kuyungurura no gusana ibidukikije.
Incamake yicyuzi
1. Hydrology
Icyuzi cy'umuringa umuringa uherereye mu kibaya. Hano hari imisozi mumajyaruguru, iburengerazuba no mumajyepfo yatandukanijwe na sisitemu y'amazi akikije. Icyuzi cyumurizo gifite ubuso bwa 5km². Hano hari amazi mu mwobo umwaka wose, kandi amazi ni menshi.
2. Imiterere y'isi
Ikibaya muri rusange kiri mu majyaruguru y'uburengerazuba-mu majyepfo y'iburasirazuba, kandi gihindukirira mu majyaruguru y'uburasirazuba ku gice cya Mizokou. Ikibaya kirakinguye, gifite ubugari bwa metero 100 n'uburebure bwa 6km. Urugomero rwambere rwicyuzi cyateganijwe ruri hagati yikibaya. Imiterere yubuso bwa banki irahanamye kandi ahantu hahanamye ni 25-35 °, aribwo buryo bwa tectonic denudation alpine landform.
3. Ubwubatsi bwa geologiya
Mugihe hategurwa gahunda yo kurwanya seepage yicyuzi cyumurizo, hagomba kubanza gukorwa ubushakashatsi bwubuhanga bwa geologiya bwakarere ka kigega. Igice cyubwubatsi cyakoze ubushakashatsi bwa geologiya yubushakashatsi bwicyuzi cy’ubudozi: nta makosa akomeye anyura mu kigega; Ubutaka bukomeye, icyiciro cyubwubatsi nicyiciro cya II; amazi yubutaka mukarere k’ibigega yiganjemo uburiri bwikirere bwikirere cyamazi; urutare ruhagaze neza, kandi hari ahantu hanini cyane ikirere gikwirakwizwa mukibanza cyurugomero, hamwe nimbaraga zikomeye. Byemejwe neza ko ikibanza cy’ubudozi ari ikibanza gihamye kandi gikwiye cyane cyane kubaka ububiko.
Gahunda yo kurwanya seepage yicyuzi
1. Guhitamo ibikoresho birwanya seepage
Kugeza ubu, ibikoresho bya artificiel anti-seepage bikoreshwa muri uyu mushinga ni geomembrane, sodium bentonite igipangu kitagira amazi, n'ibindi. yashyizwe hamwe na sodium bentonite yamazi adafite igipangu Horizontal immmeability.
2. Ikigega cyo munsi yubutaka bwamazi yo mumazi
Nyuma yo gusukurwa no kuvurwa, ikigega cya kaburimbo ya mmmm 300mm gishyirwa munsi yikigega nkigice cyo kuvoma amazi yubutaka, hanyuma hashyirwaho umwobo uhumye wamazi washyizwe munsi yikigega, hamwe numuyoboro wa DN500 usobekeranye. yashyizwe mu mwobo uhumye nkuyobora nyamukuru yo gutemba. Imiyoboro ihumye yo kuyobora imiyoboro yamazi yashyizwe kumurongo munsi yicyuzi cyumurizo. Hariho imyobo 3 ihumye yose hamwe, kandi itunganijwe ibumoso, hagati na iburyo mucyuzi.
3. Sisitemu yo kuvoma amazi yubutaka
Mu gice cy’amazi y’amazi y’ubutaka, hashyizweho umuyoboro w’amazi wa geotechnique, kandi hashyirwaho imiyoboro itwara amazi itabona hamwe n’imiyoboro y’amazi y’amazi ashyirwa muri buri mwobo w’ishami mu gace k’ibigega, uhuza umuyoboro munini uri munsi y’ikigega.
4. Gushyira ibikoresho byo kurwanya ibicuruzwa
Ibikoresho birwanya anti-seepage mu gice cy’ibigega by’umurizo bifata sodium ishingiye kuri bentonite y’amazi adafite amazi. Munsi yicyuzi cyumurizo, hashyizweho urwego rwamazi yo mumazi yubutaka. Urebye ko ari ngombwa kurinda sodium bentonite igipangu kitagira amazi, ubutaka bwa mmmm 300 z'ubutaka bwiza bushyirwa kumurongo wa kaburimbo nkigice cyo gukingira munsi ya membrane. Ahantu hahanamye, urusobe rwamazi ya geotechnique rushyirwa mubice bimwe nkigice cyo gukingira munsi ya sodium-bentonite yikingira amazi; mu tundi turere, 500g / m² geotextile yashyizweho nkigice cyo gukingira munsi ya membrane. Igice cyibumba cyumucyo mukarere ka kigega cyumurizo kirashobora gukoreshwa nkisoko yubutaka bwiza.
Imiterere ya anti-seepage hepfo yicyuzi cyumurizo nuburyo bukurikira: umurizo - sodium bentonite igipangu kitagira amazi - igitaka cya 300mm cyubutaka bwiza - 500g / m² geotextile - amazi yo mumazi yubutaka (300mm ya kaburimbo cyangwa urwego rusanzwe kandi rworoshye neza) , imiyoboro y'amazi Umuyoboro uhumye) urwego ruringaniza.
Imiterere ya anti-seepage igizwe nubudozi bwibidendezi (ntahantu hagaragara amazi yubutaka): umurizo - sodium bentonite uruganda rutagira amazi 500g / m² geotextile - kuringaniza ibice fatizo.
Imiterere ya anti-seepage kumurongo wuburebure bwikidendezi (hamwe n’ahantu hagaragara amazi y’ubutaka): umurizo - sodium ishingiye kuri bentonite y’amazi adafite amazi - igipande cy’amazi yo mu butaka (6.3mm ikomatanya imiyoboro y’amazi ya geotechniki, imiyoboro y’amazi ihumye) - kuringaniza ibice fatizo.
