Vibroflotation

I-Vibroflotation iyindlela ekhethekile yokuthuthukiswa komhlabathi esebenziselwa kakhulu emaphrojekthini akhethiwe ezisekelweni ezijulile nasezobuchwepheshe bomhlaba ukuze kukhuphuke amandla okuhamba nokuzinza kwezihlabathi ezithambile. Le ndlela yokwakha emhlabathini yedijithali isebenzisa amandla okudlidliza aphezulu ukuhlela amazakhi omhlabathi, kwehlisa ubudlelwano bokungena futhi kukhuphuke ubungako bezihlabathi, i-gravel, kanye namathuluzi alula afana nalawo. Le ndlela ibaluleke kakhulu kumaphrojekthi okwakha lapho izimo zomhlabathi zemvelo zinganele ukusekela izakhiwo ezinzima noma lapho ukulawula ukushintsha kubalulekile. I-Vibroflotation isebenza ngokufaka isibambo esisebenza ngokudlidliza, esaziwa ngokuthi i-vibratory pile hammer noma i-vibroflot, emhlabathini kuzindiza eziyinqaba ezivela ku-10 ukuya ngaphezulu kwama-100 amamitha. Iziphakamiso zenza amandla okuphazamiseka anqamule amazakhi omhlabathi ukuze avumele amazakhi omhlabathi ukuba abuyele endaweni ethambile, kuthuthukise kakhulu izakhiwo zomhlabathi ngaphandle kokudinga ukuhoxiswa noma ukususwa kwezinto. Inqubo ye-vibroflotation ngokuvamile ifaka ukufaka ithuluzi elinama-weight emhlabathini usebenzisa imishini eqhubekile noma izigebengu ezihambayo, lapho i-hammer yokudlidliza ibekelwe kumasipala akhethekile. Imishini ehamba phambili ye-vibratory inganikeza ama-frequency phakathi kuka-10 no-45 hertz enezinga lokucindezela le-5 kuya ku-15 millimeters, ukudala izimo ezinhle zokuthuthukiswa komhlabathi. Amanzi avame ukufakwa ngesikhathi senqubo ukuze kwehliswe ukuhlinzekwa phakathi kwamahlamvu omhlabathi futhi kwenze kube lula ukuhlela kabusha amazakhi, okwaziwa njengendlela yamanzi. Imishini esetshenziswa ku-vibroflotation ifaka ama-vibrators afakwe kumakhenikha, ama-vibroflotation akhethekile, nezicwecwana ezikhipha i-vibratory ezikwazi ukudala iziphakamiso ezilungiselelwe kahle. Udeep we- treatment uncike kuhlobo lomhlabathi, izimo zamanzi aphansi, kanye nemininingwane yemishini, lapho izinhlelo ze-crane-suspended vibratory zanika amandla ama-deep treatment angakaze afinyelelwe. Ukuqapha ikhwalithi kubalulekile, ngokuvamile kuhlanganisa ukuhlola ukuhlinzeka okujwayelekile, ukuhlola ukujula kwama-cone, kanye nokubheka ukuhamba ukuze kuqinisekiswe ukusebenza kahle kokuthuthukiswa komhlabathi nokuthi bakhiqizwe amandla okuthwala acace kakhulu. I-Vibroflotation isebenza kangcono emhlabathini angenamabhasi, kufaka phakathi izihlabathi, i-gravel eyisihlabathi, ne-gravel eyisihlabathi, futhi iba nekhono eliphansi emhlabathini onamakhilo aphezulu noma umhlanga. Le ndlela ibaluleke kakhulu kumaphrojekthi afaka izikhwama zokugcina ezinkulu, izikhungo zezimboni, ukufakwa kwemishini enzima, nezakhiwo ezidinga amandla okuthwala ahlukeneyo nokushintshwa okuncane. Izicelo zifaka izikhungo zokuthutha, izisekelo zezitezi ezisemanzini, ukunciphisa ukungena emikhakheni ye-seismic, kanye nokubuyisela emuva kwezimo ezinzima zomhlaba ngaphansi kwezinto ezikhona. Le ndlela ibaluleke kakhulu lapho ukufakwa kwepile ejulile kungabizi kahle noma lapho kudingeka ukuthi kube nokudlidliza okuncane kanye nosizi oluphansi uma kuqhathaniswa nalokhu okwakujwayelekile. I-Vibroflotation isetshenziswa futhi ngemva kwezinye izindlela zokuthuthukiswa komhlabathi futhi njengendlela yokulungiselela ngaphambi kokufaka ama-piles aphonsiwe noma adalwe endaweni. Ukubhekwa kwemvelo kwenza i-vibroflotation ibe nentshisekelo ngoba ikhulula isidingo sokufaka umhlabathi noma ukuhoxiswa okukhulu, kwehlisa ukulahleka kwezinto nasemathubeni okuhamba ngesikhathi sokuhlinzekwa kwezixazululo ezizinzile ezimweni ze-geotechnical ezinselele.
