Ama-Cranes Asebenza Ngokuqinile E-Dynamic Compaction

Amakhreyini anzima okwenza ukwenziwa kokuhlanganiswa kwedinamiki awumqondo obalulekile ekuzinziseni umhlabathi nasekuthuthukiseni umhlaba, ikakhulukazi kubaphrojekthi abafuna ukulungiswa komhlabathi okukhulu ngaphambi kokufakwa kwamafonti ajulile noma izinhlelo zokuphatha umthwalo. Le ndlela ethile ibandakanya ukuwa kokulandelana kokuphakanyiswa kwezins weight ezinzima ezivela phezulu ukuze kudluliseke amandla okukhipha emhlabathini. Le nqubo ikhulisa umhlaba ongemihle noma ophansi, ithuthukisa amandla okuphatha, inciphisa amathuba okuhlungu, futhi ithuthukisa ukuzinza komhlaba jikelele ezindaweni ezinkulu. Amakhreyini anzima abe yinsiza eyinhloko yalolu work, anikela ngamathuba aphakeme okupaka, ukuzinza, kanye nokulawula ukunemba ukwenza izinhlelo zokuhlanganiswa kwedinamiki ngokuphepha nangempumelelo ezindawo zokwakha lapho izindlela ezivamile zokuhlanganiswa kwe-vibratory noma ezimile zikhombisa ukuba nezinkinga zokuthola izimfuneko zokuhlosiwe kwezobunjiniyela. Izilungiselelo zethuluzi zokuhlanganiswa kwedinamiki zisebenzisa amakhreyini anokukwazi okujwayelekile okuhlelwa phakathi kuka-100 no-500+ amathani, aphakanyiswe ngezinsiza ezikhethekile zokuphakamisa nezinhlelo zokuxhuma eziklanyelwe ukuphatha imithwalo yokuphazamiseka. Iziweight zokuhlanganiswa ngokwazo—ngokuvamile zikwazi phakathi kuka-10 no-40 amathani—zilungiswa zifeze phezulu (ngokuvamile ama-15 kuya kwe-30 metres) futhi zikhishwe ezimweni ezijwayelekile ezenzakalayo ezindaweni eziboniwe. Amandla adluliselwa ngexesha, alinganiswa ngezinga le-kilojoule-meters, akalingeni ngokucacile ngokususelwa ekwakhekeni komhlabathi, ukuphakama okumelwe kuthuthukiswe, nezimfuneko zokuphatha. Imisebenzi yakamuva ifaka phakathi izinsiza zokubhekela ezihlanganisa amaphaneli okukhula nezinsiza zokusebenza ukuze kuqondiswe impendulo yomhlaba nokuqinisekisa ukuthi izimfuneko zokuhlanganiswa kwendaba ezichaziwe zifezekile. Abasebenzisi kumele babe nofundo olukhethekile ngezindlela zokuhlanganiswa kwedinamiki, ukukala imithwalo, kanye nezinhlelo zokuphepha, njengoba ubunjalo bolwazi obunamandla bokusebenza kudinga ukunakwa okukhulu kokubeka amathuluzi, izindawo zokuphepha kwezisebenzi, kanye nezimo zemvelo. Ukwakha umhlabathi nge amakhreyini anzima kube nomphumela ophumelelayo ekwelathweni kwemithombo ebonakalayo, ukwakha izinto eziphathekayo, izindawo ezinzima eziphakathi, kanye nezinhlelo ezihlukahlukene zomhlabathi lapho izindlela ezivamile zingatholi ukuhlonzwa okujwayelekile. Le ndlela ibhekana nezimo zomhlabathi ezithile kufaka phakathi imithombo yamanzi, umhlaba ogcwele uye, kanye nezindawo ezenziwe ngezandla ezikhombisa amathuba aphezulu okuhlunga ngaphansi kwemithwalo yokwakha. Ukusetshenziswa kuhambisana nezimboni ezihlukahlukene zokwakha: izikhungo ezinkulu zezimboni ezifuna amapulatifomu azinzile, amaphrojekthi wezakhiwo kuhlanganisa umugqa wama-airport nezinsika zezinja, izikhungo zethuli nezinsiza zokugcina, ukuthuthukiswa kwezentengiso kanye nekhaya ledata, kanye nezinkulu ezikhangayo noma ezimele ezindaweni ezingezona ezinhle. Le ndlela ihlambululeka kalula emaphrojekthini afanelekile njengensiza yokuqala yokulungiswa komhlaba, ikakhulukazi uma ihlanganiswa nokushaywa kwezibani, ukufakwa kwe-caison, noma ezinye izindlela zokwakhiwa ezijulile. Ngokwakha izendlalelo zomhlabathi ezithuthukisiwe nezithambile ngaphambi kokufakwa kwezinsiza, ukwenziwa kwe-dynamic kunciphisa izingozi zokuhlunga okwehlukile, kuthuthukisa ukufana kokungqubuzana kwemikhono ezindaweni ezihlukahlukene, futhi kunciphisa izinkinga zokugcina isikhathi eside. Le ndlela ibhekisela ekuhlanganyeleni kwezindleko ezithokozisayo zokususa ngokuphelele nokufakwa, kuyilapho ihlinzeka ngezimiso zokuhlosiwe ezivumelanayo nezindlela ezinhle kakhulu zokwenza umhlaba, kwenza kube ithuluzi elibalulekile kubanjiniyela be-geotechnical abaphatha izinselelo ezithile zomhlaba kumaphrojekthi okuhlole neziqu zezimboni zomhlaba.
