Inethi yokukhupha amanzi edityanisiweyo enemilinganiselo emithathu isetyenziswa kakhulu kwimisebenzi emikhulu. Ngoko ke, kufuneka idityaniswe njani ngexesha lokwakha?
1. Uhlengahlengiso lwesikhokelo esidibeneyo
Xa ubeka inethi yokukhupha amanzi edityanisiweyo enamacala amathathu, lungisa indlela yomqulu wezinto ukuqinisekisa ukuba ubude becala lomqulu wezinto bume nkqo kwicala eliphambili lendlela okanye iprojekthi. Olu hlengahlengiso luvumela inethi yokukhupha amanzi ukuba igcine ukusebenza kakuhle kokukhupha amanzi xa ithwala imithwalo, iphucule indlela yokuhamba kwamanzi, kwaye iphucule ukusebenza kakuhle kokukhupha amanzi. Ukuba icala alilungiswanga kakuhle, linokukhokelela ekutsaleni amanzi kakubi okanye ekuqokeleleni kwamanzi kwindawo ethile, okuchaphazela isiphumo seprojekthi.
2. Ukupheliswa kwezinto kunye nokudibana kwazo
Inethi yokukhupha amanzi edityanisiweyo enamacala amathathu kufuneka ipheliswe, kwaye ii-geotextile ezikwi-geonet cores ezikufutshane mazigqunywe kwicala le-material roll. Xa ugqunywe, qiniseka ukuba i-geotextile ithe tyaba kwaye ayinamibimbi, kwaye ubude bogqunywe buhlangabezana neemfuno zoyilo. Ngokubanzi, ubude bogqunywe obude abungaphantsi kwe-15cm, kwaye ubude bogqunywe obunqamlezileyo bulawulwa ngaphakathi koluhlu lwe-30-90cm. Ubude bogqunywe obunganelanga bunokubangela amandla angonelanga kwi-joint, okuchaphazela ukuzinza kwenethi yokukhupha amanzi; ngelixa ugqunywe obugqithisileyo bunokunyusa inkunkuma yezinto kunye nobunzima bokwakha.
3. Ukusetyenziswa kwezihlanganisi
Kwinkqubo yokudibanisa, ukukhetha nokusebenzisa izihlanganisi kubaluleke kakhulu. Ngokubanzi, kusetyenziswa izikhonkwane zeplastiki ezimhlophe okanye ezimthubi okanye imitya yepolymer ukudibanisa ii-geonet cores zemiqolo ye-geotextile ekufutshane. Xa udibanisa, sebenzisa izihlanganisi ukuzilungisa ngamaxesha athile (njenge-30cm okanye i-1m) kubude bomqukumbelo wezinto. Izihlanganisi kufuneka zibe namandla aneleyo kunye nokuqina ukuqinisekisa ukuzinza kwamalungu. Ukuba izihlanganisi zisetyenziswa ngendlela engafanelekanga, amalungu anokukhululeka okanye awe, nto leyo echaphazela isiphumo sokukhupha amanzi kwinethi yokukhupha amanzi.
4. Ukulungiswa kwee-geotextile ezidibanayo
Ukuba inethi yokukhupha amanzi edityanisiweyo enamacala amathathu ibekwe phakathi kwesiseko, isiseko kunye ne-subbase, ii-geotextile ezidityanisiweyo kufuneka zilungiswe. Iindlela zokulungisa ziquka ukuwelda okuqhubekayo, ukuwelda kwentloko ethe tyaba okanye ukuthungwa. Xa uthunga, qiniseka ukuba ii-welds zicocekile, zintle kwaye azinazo ii-welding ezityibilikayo kunye nokutsiba; xa uthunga, ukuthungwa kwentloko ethe tyaba okanye ukuthungwa ngokubanzi kunokusetyenziswa ukuhlangabezana neemfuno zobude obuncinci bokuthungwa. Ukulungisa kunokuphucula amandla kunye nokuzinza kwamalungu kwaye kuthintele ii-geotextile ekubeni zisuswe okanye zonakale ngexesha lokufakwa kwezizalisi.
5. Unyango olukhethekileyo lokusingqongileyo
Kwiindawo ezikhethekileyo, njengaxa kukho amatye arhabaxa phezu komqamelo wesiseko segrabile, ukuze kuthintelwe ukuba ingabhobozi i-geomembrane engangeniyo amanzi, kufuneka kusasazwe umaleko omncinci wesanti exutyiweyo (ubude obuyi-3-5cm) kwaye uqengqelwe phezu komqamelo wesiseko segrabile. Umaleko wesanti kufuneka ugubungele ngokupheleleyo umphezulu womqamelo wesiseko segrabile, kwaye akufuneki kubekho grabile enobukhulu besuntswana obungaphezulu kwe-4mm kumaleko wesanti. Xa kusakhiwa kwiindawo ezibandayo okanye ezinobushushu obuphezulu, kufuneka kuthathwe amanyathelo okukhusela afanelekileyo, anjengezihlanganisi zokufudumeza kunye nokulungisa ixesha lokwakha, ukuqinisekisa ukuba umgangatho wamalungu awuchaphazeleki yindalo esingqongileyo.
Njengoko kunokubonwa koku kungasentla, unyango oludibeneyo lwenethi yokukhupha amanzi edityanisiweyo enemilinganiselo emithathu lukhonkco oluphambili kwinkqubo yokwakha, oluhambelana ngokuthe ngqo nesiphumo sokukhupha amanzi kunye nokuzinza ngokubanzi kwenethi yokukhupha amanzi. Ukulandela iinkcukacha zokulungiswa kwendlela edibeneyo, ukupheliswa kwezinto kunye nokugqithisana, ukusetyenziswa kwesixhumi, ukulungiswa kwe-geotextile edibeneyo kunye nonyango olukhethekileyo lokusingqongileyo kunokuqinisekisa amandla kunye nokuzinza kwamalungu kunye nokuphucula ukusebenza kakuhle kokukhupha amanzi kunye nobomi benkonzo yenethi yokukhupha amanzi.
