Amathrekhi anomast eWide-Angle (okubambekayo)

Amarigidhi wokupholisa ama-anchors ahamba nge-crawler anemast aphakeme afaka ingqalasizinda ekhethekile yokwakha izisekelo ezijulile, eyenzelwe ukusebenza okuphakeme kokugodla ezindaweni ezinzima ze-geotechnical. Lezi zinqola zenza ukufakwa kweziqiniseko zomhlaba ezimise okungafani, okuvumela ochwepheshe ukuba baphendule izinqubo zokugonda ukuze zihambisane nezimo ezithile zesayithi nezidingo ze-load. Uhlelo lwe-mast olukhulu lwenza kube lula ukuba abasebenzi bafezekise ukugonda okunqamulelayo kusuka kokungaphezulu kuze kube sezingeni eliphakeme, kuhlanganisa ubunye obukhulu ekufakeni ama-anchors. Le njongo ibalulekile ekutholeni izinselelo ezinzima zezisekelo lapho ukugonda okwejwayelekile kunganele, ikakhulukazi emisebenzini yokuzinza kwezakhiwo, ukufakwa kwemidlalo yokugcina, kanye nosizo lwemisebenzi engaphansi komhlaba lapho imithwalo ibalulekile futhi kudingeka izinhlelo zama-anchors ezihambisana nemikhondo eminingi. Indlela yobuchwepheshe engemuva kokugondiswa kwe-mast enkulu ibandakanya izinto zokulungisa ezinemininingwane ezigcina ukuzinza kokugonda ngesikhathi i-mast isebenza ezingeni eliphakeme kulesi simo se-horizontal. Iziphakathi ezinamathiselwe ku-crawler zinikeza ukuhamba okuhle ezindaweni ezingalingani kanye nezindawo ezivinjwe, okubalulekile emisebenzini yezezimali ethinta amagquma noma izakhiwo ezikhona. Lezi zinqola ngokuvamile zisebenzisa izinhlelo zokugondiswa kwe-rotary ezineziqondiso zokugonda ezilungisekayo nezilawulayo ukuze ziphumelele emifudlaneni yembali ethile - kusukela kukhilimu oluthambile nezinsalela kuya kumamaki anempilo. I-rig yokugoda kufanele igcine umfutho ofanayo nokujikeleza ngenkathi i-mast ithokozisa, kudinga izinhlelo ze-hydraulic ezithuthukile kanye nezikhangiso zokulawula ze-elekthronikhi. Abasebenzi basebenzisa ama-inclinometer aphuma emibhoshongweni kanye nezinsiza zokuhlola ukuqinisekisa ukuthi izinqubo zokugonda zihambelana nezincazelo zomqondo, kuqinisekisa ukuthi ukufakwa kweziqinisekiso kufinyelela ezingeni ezilinganisiwe nezijulile. Inqubo yokufaka ama-anchors iqhubeka ngalesi sikhathi sokuhlola, lapho imishini yokuhlukanisa ephezulu ifaka i-cement noma i-chemical grout emabhodweni afakiwe, idala ubudlelwano obungapheli obuphakela izimoto nezinsiza ezizungezile. Izicelo zokuchema ngamast omakhasi aphezulu zibhekene nemikhakha eminingi yokwakha nezinsiza ze-geotechnical. Iziphakamiso zokuzinza kwemikhondo zisebenzisa ama-anchors akhulayo ukuze kuqinise iziqongo ezingazinzile ezibhekene nokukl webala noma ukuchitha, lapho ama-arrays ama-anchors adalwe ukuze aphathe izinhlelo ezithile zokwehluleka ezitholakele ngokuhlola kwe-geotechnical. Izinhlelo zokwesekwa zesikhashana zezigebengu ezijulile zisebenzisa ukugonda kwe-anchors ukuhlinzeka ukufakwa okuhambelana, ikakhulukazi ezindaweni zasemadolobheni lapho izindonga eziphathekayo noma imihlangano ye-diaphragm idinga ukuhlinzekwa. Imisebenzi ye-infrastructure yangaphansi komhlaba - kufaka phakathi ukwakhiwa kwezintambo, ukumba amabhakede, kanye nokuthuthukiswa kwe-subway - kuncike ezinhlelweni ze-anchor ezikhaliphayo ukuze kujiye iziqubulo zemanzi kwangathi ekugcineni akukho kuvaliwe kwendawo ngezikhathi zokwakha. Imisebenzi yokugcina izakhiwo izuza ekulinganiseni okukhuluma ngezindlela ezibhalwe phansi kahle, ikakhulukazi lapho izici zomhlaba zifaka izakhiwo eziphakeme noma ziqukethe amathe amancane. Izimo zomhlabathi nosawoti zithinta kakhulu ukusebenza kwe-mast enkulu. Izinto eziphilayo zophondo ezineziqonde ezimile ezifaka ama-anchors ahlala isikhathi eside ngaphandle kokusekelwa futhi zenza izindlela zokugonda ezibukeka kahle. Izici ezinganhlanga ne-rok mix zidinga ukuhlela kwezobuchwepheshe okucacile futhi ngokuvamise kudingeka izinhlelo zokuhlola ukuqinisekisa ubuqiniso bembhoshongo. Izindawo ezicindezelwe kanye nezimo eziphakeme zendawo yamanzi zidinga izindlela zokuhlola ezikhethekile nezinyathelo zokuhlola imbhobho. Umongo owujulile wezokwakha ama-anchors kudinga ukuhlolwa kwe-geotechnical okuphelele kanye nokwakhiwa kobuchwepheshe, kucacisa izindawo zokugonda, imithwalo ye-anchor, amajikijolo, kanye nezinhlelo zokhuni ezithuthukisa ukusebenza kwesisekelo ngenkathi zigcina ukuphepha kokwakha kanye nezindleko ezisebenzayo phakathi kwezimo ezihlukahlukene zomhlaba.
