一. Ukulungiselela ulwakhiwo
1, Unyango lwenqanaba lengca
Ngaphambi kokubeka inethiwekhi yokukhupha amanzi ye-geocomposite, umaleko osisiseko kufuneka ucocwe kakuhle ukuqinisekisa ukuba akukho zikhonkwane ziqinileyo ezifana negrabile kunye neebhloko kumphezulu, kwaye ubunzulu kunye nokuqina okufunekayo kuyilo kufuneka kuhlangatyezwane nako. Ubunzulu abuyi kuba ngaphezu kwe-15 mm, Iqondo lokuqina kufuneka lihlangabezane nemigangatho yoyilo lobunjineli. Umphezulu womaleko osisiseko kufuneka ugcinwe womile ukuze kuthintelwe impembelelo yokufuma ekusebenzeni kwenethi yokukhupha amanzi.
2, Ukuhlolwa kwezinto
Ngaphambi kokuba kwakhiwe, inethiwekhi yokukhupha amanzi ye-geocomposite kufuneka ihlolwe ngokupheleleyo ukuqinisekisa ukuba ayonakalanga okanye ayonakaliswanga, kwaye ikwahlangabezana neemfuno zoyilo. Ingqwalasela ekhethekileyo kufuneka inikwe ekujongeni inxalenye engundoqo yenethi yokukhupha amanzi ukuqinisekisa ukuba isakhiwo sayo esinamacala amathathu sigqibelele kwaye asinakuguquguquka okanye konakala.
3. Iimeko zeNdalo
Xa kubekwa inethiwekhi yokukhupha amanzi ye-geocomposite, ubushushu bangaphandle kufuneka bube yi-5 ℃. Ingenziwa phantsi kweemeko zemozulu ezingaphezulu, amandla omoya angaphantsi kwenqanaba lesi-4, kwaye kungabikho mvula okanye ikhephu, ukuze kuqinisekiswe umgangatho wolwakhiwo.
二. Iinkcukacha zokubeka
1, Ulwalathiso lokubeka
Iinethiwekhi zokuhambisa amanzi ezibizwa ngokuba yi-geocomposite kufuneka zibekwe phantsi kwethambeka, ukuqinisekisa ukuba ubude bukwicala lokuhamba kwamanzi. Kwezinye iindawo ezinde nezithe nkqo, kufuneka kuqwalaselwe ngokukodwa ukusebenzisa ubude obupheleleyo be-material roll phezulu kwethambeka ukuze kuthintelwe ukuchaphazela impembelelo yokukhupha amanzi ngenxa yokusikwa.
2, Ukuphathwa kweMiqobo
Xa udibana nemiqobo ngexesha lokubeka, njengemibhobho yokukhupha amanzi okanye imigodi yokubeka esweni, sika inethi yokukhupha amanzi uze uyibeke ecaleni kwemiqobo ukuqinisekisa ukuba akukho msantsa phakathi kwemiqobo nezinto ezisetyenziswayo. Xa usika, i-geotextile esezantsi kunye ne-geonet core ye-composite drainage net kufuneka idibane nemiqobo, kwaye i-geotextile ephezulu kufuneka ibe nomda owaneleyo, ukuze ikwazi ukugotywa phantsi kwenethi yokukhupha amanzi ukukhusela i-geonet core eveziweyo.
3, Iimfuno zokubeka
Xa ubeka, inethi yokukhupha amanzi kufuneka ilungiswe kwaye igudiswe, kufutshane nomaleko osisiseko, kwaye akufuneki kubekho ukugqwetheka, imibimbi okanye i-Stack Phenomenon enzima. Inxalenye ekufutshane yomphetho odibeneyo kwicala lobude benethiwekhi yokukhupha amanzi edibeneyo ubuncinane yi-100 mm, Sebenzisa kwakhona i-HDPE Plastic belt binding, ibhande lokubopha kufuneka libe kwi-Stack enzima. I-shaft ye-geonet enye ubuncinane iphakathi kwenxalenye kwaye idlula kwi-shaft ye-geonet enye ubuncinane. Isithuba sokubopha esidibeneyo ecaleni kwethambeka elisecaleni yi-150 mm, Isithuba sokubopha phakathi kwamalungu kuzo zombini iziphelo zomsele wokubambelela kunye nezantsi kwendawo yokulahla inkunkuma nayo yi-150 mm.
三. Iinkcukacha ezihambelanayo
1, Indlela yokudibanisa i-Lap
Xa inethi yokukhupha amanzi ye-geocomposite ijikeleziswa, kufuneka kusetyenziswe izibophelelo zeplastiki okanye izinto zepolymer ukudibanisa, kwaye iibhanti zesinyithi okanye izibophelelo zesinyithi akufuneki zisetyenziswe. Umbala wokudibanisa kufuneka ube mhlophe okanye umthubi ukuze kube lula ukujonga. Kwi-geotextile ephezulu, ubunzima obuncinci yi-Stack 150 mm ； I-geotextile esezantsi kufuneka ijikeleziswe ngokupheleleyo, kwaye i-geotextile ephezulu inokudityaniswa ngokuthunga okanye ukuwelda. Ubuncinane umqolo omnye weenaliti ezinemisonto emibini kufuneka usetyenziswe kwijoyinti, umsonto wokuthunga kufuneka ube nemisonto emininzi, kwaye uxinzelelo oluncinci aluyi kuba ngaphantsi kwe-60 N ， Kufuneka kwakhona ibe nokugqwala kweekhemikhali kunye nokumelana ne-ultraviolet okufana nee-geotextile.
2, iinkcukacha ezihambelanayo
Ngexesha lenkqubo yokugquma, kufuneka kuqwalaselwe ngokukodwa ukutywinwa kwenxalenye egqumayo ukuze kuthintelwe ukufuma okanye amasuntswana amancinci ukuba angangeni kwisiseko se-drainage mesh. Indlela yokubopha ngobushushu, ubushushu kufuneka bulawulwe ngokungqongqo ukuze kuthintelwe ukutsha kwi-geotextile. Zonke iindawo ezigqumayo kufuneka zihlolwe ngononophelo ukuqinisekisa ukuba akukho nto "engekhoyo yokuthungwa", kwaye ukuba kukho nayiphi na into efunyenweyo, imithungo kufuneka ilungiswe ngexesha.
Ukuzalisa i-backfilling kunye nokuxinana
1, Izinto zokugcwalisa umva
Emva kokuba uthungelwano lokukhupha amanzi lubekwe, unyango lokugcwalisa amanzi emva kwexesha kufuneka lwenziwe. Izinto zokugcwalisa amanzi emva kufuneka zenziwe ngegrabile okanye isanti elungisiweyo kakuhle, kwaye kuphephe ukusebenzisa amatye amakhulu ukuze kungalimazi uthungelwano lokukhupha amanzi. Ukugcwalisa amanzi emva kufuneka kwenziwe kumacala omabini ngaxeshanye ukuze kuthintelwe ukuguquka kothungelwano lokukhupha amanzi ngenxa yomthwalo obekwe kwicala elinye.
2, iimfuno zokuxinana
Izinto ezizalisa emva kufuneka ziqiniswe zibe ziingqimba, kwaye ubukhulu bomaleko ngamnye mabungadluli kwi-30 cm. Ngexesha lokuqiniseka, kufuneka kusetyenziswe iindlela ezilula zoomatshini okanye zezandla ukuze kuthintelwe uxinzelelo olugqithisileyo kwinethiwekhi yokukhupha amanzi. Umaleko ozalisa emva kufuneka uhlangabezane noxinano kunye nobunzima obufunekayo kuyilo.
Ukwamkelwa kunye nokugcinwa
1. Iikhrayitheriya zokwamkelwa
Emva kokuba ulwakhiwo lugqityiwe, umgangatho wokubekwa kwenethiwekhi yokukhupha amanzi ye-geocomposite kufuneka wamkelwe ngokupheleleyo. Umxholo wokwamkelwa uquka kodwa awupheleli apho: indlela yokubekwa kwenethiwekhi yokukhupha amanzi, umgangatho wokudibana, ubuncinci kunye nokuba tyaba komaleko wokugcwalisa umva, njl. Kwakhona jonga ukuba inkqubo yokukhupha amanzi ayithintelwanga kwaye uqinisekise ukuba isiphumo sokukhupha amanzi siyafezekisa injongo oyifunayo.
2, Ulondolozo kunye nokuhlolwa
Ngexesha lokusetyenziswa, inethiwekhi yokukhupha amanzi ye-geocomposite kufuneka ihlolwe kwaye igcinwe rhoqo. Umxholo wokuhlolwa uquka ukuthembeka kwenethi yokukhupha amanzi, ukuqina kweendawo ezidibeneyo kunye nesiphumo sokukhupha amanzi. Ukuba kufunyenwe iingxaki, kufuneka zijongwane nazo kwangethuba ukuze kuthintelwe ukuphazamisa uzinzo kunye nokuqina kwesakhiwo sobunjineli.
Njengoko kunokubonwa koku kungasentla, kuphela yi-Geocomposite drainage net echanekileyo enokuqinisekisa ukusebenza kwayo ngokupheleleyo. Ukususela ekulungiseleleni ulwakhiwo ukuya ekubekeni, ukudibana, ukuzalisa umva kunye nokwamkelwa, zonke iinkalo kufuneka zithobele ngokungqongqo iimfuno zeenkcukacha ukuqinisekisa ukuba yonke inkqubo iyahlangabezana neemfuno zoyilo. Kungale ndlela kuphela apho ukusebenza kokukhupha amanzi kwinethiwekhi yokukhupha amanzi ye-geocomposite kunokuthi kuphunyezwe ngokupheleleyo kwaye uzinzo kunye nokuqina kwesakhiwo sobunjineli kuphuculwe.
