Iindaba

Ngaphantsi kweemeko zemvula enzima, i-geotextile yokukhusela i-slope structure inokusebenzisa ngokufanelekileyo umphumo wayo wokukhusela. Kwiindawo apho i-geotextile ingagqunywanga, iinqununu eziphambili zisasaza kwaye zibhabha, zenze ezinye imigodi; Kwindawo egqunywe yi-geotextile, amathontsi emvula abetha i-geotextile, asasaza uxinzelelo kwaye anciphisa kakhulu amandla empembelelo kumhlaba wokuthambeka. Emva kokhukuliseko lwepetal, umthamo wokungenwa womzimba wasebukhosini uyancipha ngokuthe ngcembe, kwaye ukuqengqeleka kwethambeka kuye kube njalo. I-runoff yenziwa phakathi kwe-geotextiles, kwaye i-runoff isasazwa kwi-geotextile, ibangela ukuba amanzi emvula aqhube phantsi kwimeko ye-laminar. Ngenxa yempembelelo ye-geotextiles, i-grooves eyenziwe yi-runoff inzima ukudibanisa, kunye nenani elincinci le-grooves kunye nophuhliso olucothayo lwe-grooves. Ukhukuliseko lweegrooves ezintle aluqhelekanga kwaye kunzima ukwenza. Ukhukuliseko lomhlaba luncitshiswe kakhulu xa kuthelekiswa nethambeka elingenanto, kunye namasuntswana omhlaba adibana kwicala elingaphezulu le-geotextile kunye nemijelo evalekileyo kunye nemingxuma ethile phezulu.

Ngaphantsi kweemeko zemvula enkulu, izakhiwo eziphakanyisiweyo ze-geotextile zinokukhusela ngokufanelekileyo amathambeka, kwaye iyonke, i-geotextile inokugubungela izakhiwo eziphakanyisiweyo. Xa imvula ibetha i-geotextile, inokukhusela ngokufanelekileyo izakhiwo eziphakanyisiweyo kunye nokunciphisa impembelelo kubo. Kwinqanaba lokuqala lemvula, ukuthambeka okude kwesakhiwo esiphumayo kutsala amanzi amancinci; Kwinqanaba lamva lemvula, i-slope yesakhiwo esiphumayo sifunxa amanzi amaninzi. Emva kokhukuliseko, umthamo wokungena womhlaba uyehla ngokuthe ngcembe, kwaye ukubaleka kwethambeka kuye kwenzeke. I-runoff yenziwa phakathi kwe-geotextiles, kwaye ukuhamba ngesakhiwo esiphakanyisiweyo kuvaliwe, okubangelwa ukuhamba okucothayo. Ngexesha elifanayo, iinqununu zomhlaba ziqokelela kwindawo ephezulu yesakhiwo esiphakanyisiweyo, kwaye ukuhamba kwamanzi kuchithwa yi-geotextile, kubangela ukuba i-runoff iqhube kwi-laminar state. Ngenxa yobukho bezakhiwo ezijikelezayo, i-grooves eyenziwe yi-runoff inzima ukudibanisa, kunye nenani elincinci le-grooves kunye nophuhliso olucothayo. Ukhukuliseko lweegrooves ezintle luphuhliswe kancinci kwaye alukwazi ukubunjwa.

Ukhukuliseko lomhlaba luncitshiswe kakhulu xa kuthelekiswa nethambeka elingenanto, kunye namasuntswana adibana kwicala elingaphezulu lezakhiwo ezivelelayo kwaye avale imisele kunye neminye imingxuma phezulu. Impembelelo yayo yokukhusela ibalasele kakhulu. Ngenxa yempembelelo ethintelayo yezakhiwo eziphumayo kumasuntswana omhlaba, umphumo wokukhusela ubonakala ngakumbi kunezakhiwo ezingenayo.

Kwinkqubo yokwakhiwa kwe-geotextile, ukwenzela ukuba kuphuculwe umgangatho wokwakhiwa kobunjineli kunye nokuqinisekisa ukusebenza kakuhle kwe-geotextiles, le miba ilandelayo kufuneka inikwe ingqalelo. Okokuqala, thintela i-geotextiles ukuba yonakaliswe ngamatye. Ngenxa yelaphu elifana nendalo ye-geotextiles, xa libekwe kwigrabile, lisikwa ngokulula ngamatye abukhali ngexesha lokudibana nale gravel, ethintela ukusetyenziswa okusebenzayo kokucoca kunye nokuqina kwazo, ngaloo ndlela ziphulukana nexabiso labo lobukho. Kulwakhiwo lwekhonkrithi, kuyimfuneko ukubeka uluhlu lwesanti ecocekileyo phantsi kwe-geotextile okanye ukwenza umsebenzi wokucoca ofanelekileyo ukuze udlale indima efanelekileyo yokukhusela kunye nokukhusela. Okwesibini, ukusebenza kwe-tensile ye-geotextiles elukiweyo yomelele ngokubanzi kwicala le-longitudinal kunakwicala elinqamlezayo, kunye nobubanzi obuphakathi kwe-4-6 yeemitha. Kufuneka zihlanjululwe ngexesha lokwakhiwa komlambo, ezinokukhokelela ngokulula kwiindawo ezibuthathaka kunye nomonakalo wangaphandle. Nje ukuba i-geotextiles ihlangabezane neengxaki, akukho ndlela ilungileyo yokuzigcina ngokufanelekileyo. Ngoko ke, ekwakhiweni kwekhonkrithi, ingqwalasela kufuneka ihlawulwe ekwandiseni ngokuthe ngcembe unxweme lomlambo ukuthintela ukuqhekeka ngexesha lokubeka. Ekugqibeleni, ngexesha lenkqubo yokwakha isiseko, ubunzima bomthwalo kufuneka bunyuswe ngokuthe ngcembe kwaye uxinzelelo kumacala omabini kufuneka lugcinwe ngendlela efanayo njengoko kunokwenzeka. Ngakolunye uhlangothi, kunokuthintela umonakalo okanye i-sliding ye-geotextiles, kwaye ngakolunye uhlangothi, inokuphucula umsebenzi wokuhambisa amanzi eprojekthi yonke, ukwenza isiseko sizinzile.
