Amathuba Okuphakamisa (Tampers)

Emkhakheni wokwakha izisekelo ezijulile kanye neziqu ze-geotechnical, ukusetshenziswa kwezinsika zokucindezela, ezivame ukubizwa nge-tampers, kudlala indima ebalulekile ekukhuleni kwemisebenzi yokwakha kanye nokuphathwa kwezinsika. Zenzelwe njengengxenye yemishini yokucindezela edlulele, lezi zinsika ezisindayo ziwelwa ukusuka ebangeni elinqunyiwe phezulu emhlabeni ukuze ziqinise umhlabathi ophukile noma ongenampumeleli, ngaleyo ndlela kuthuthukiswe izimo ze-geotechnical zendawo. Le nqubo ibalulekile ekulungiseleleni umhlaba wezinhlelo ezihlukahlukene, kuhlanganisa ukufakwa kwezinduku, izisekelo zokwakha, nezakhiwo ze-pavement. Umsebenzi wezinsika zokucindezela ulula kodwa ophumelelayo. Ngokusebenzisa amandla e-gravitational, lezi zinsika zizuza amandla amakhulu okuphazamiseka uma zihlala emhlabeni. Lolu suku lungacindezela amaqoqo omhlabathi, kunciphisa izikhala futhi kukhuphule ubuningi, obalulekile ekusekeleni izakhiwo ezinzima. Ukuvuma kwabantu bokucindezela kuncike ezinhlelweni ezahlukahlukene, kuhlanganisa nesisindo se-tamper, ukuphakama kokuwela, kanye nohlobo lomhlaba. Ngokuvamile, izinsika zokucindezela zingaba phakathi kuka-1,000 kuya ku-10,000 pounds noma ngaphezulu, nezinga lokuwela elihlukile ngokwezimfuneko zomsebenzi othile. Izicelo ezinkulu zezinsika zokucindezela emsebenzini wokwakha izisekelo ezijulile kanye nezobuchwepheshe zihlanganisa izindlela zokuthuthukisa umhlaba, ukulungiselela indawo yokwakha, kanye nokunciphisa izingozi ezihlobene nokuhlala nokukhucululwa emithonjeni ye-seismic. Zizoba namandla kakhulu ezindaweni ezinezinsika eziphukile noma izindawo zokugcwalisa, lapho izindlela ezijwayelekile zokucindezela zingase zibe neqhaza elikhulu. Ngokuthuthukisa izimpawu zomhlabathi, ama-tamper asiza ekwenzeni izakhiwo njengemigwaqo, izakhiwo eziphezulu, nezinsiza zezimboni ziqinile, kuqinisekisa ukusebenza isikhathi eside nokuphepha. Uma kukhethwa izinsika zokucindezela, izici eziningi kufanele zicabangele ukuqinisekisa ukusebenza kahle kwezicelo ezithile. Isisindo nesakhiwo se-tamper kufanele sivumelane nezimpawu zomhlaba kanye hlubuku lokucindezela okudingekayo. Ngaphezu kwalokho, ukusebenza kahle okuqhubekayo kungathintwa uhlobo lwezinto ezisebenza ngokuzenzakalelayo ezisetshenziswe, njenge-system ye-drop hammer, evumela ukuphakama kokuwela okuhlelekile kanye nezinguquko zamandla okuphazamiseka. Ukuqonda umkhawulo wombono, kuhlanganisa nezici zemvelo nezimo ze-site, kuzokwakha ukufaneleka kokukhetha isisindo se-tamper esifanele. Ngokufingqa, izinsika zokucindezela, noma ama-tamper, azisebenzi kahle ezimeni zokwakha izisekelo ezijulile kanye ne-engineering ye-geotechnical. Ikhono lazo lokuthuthukisa ubuningi nemisebenzi yendawo kusekela impumelelo yezinhlelo zokwakha ezihlukahlukene. Njengoba amabhizinisi efuna ukuthuthukisa ukusetha kwazo nokuqhuba izisekelo, ukusebenzisa izinsika zokucindezela eziphezulu ezivela kumakethe yokuhweba eqinisekisiwe kuqinisekisa ukuthi zisebenza kahle ezinhlelweni zazo. Kungabe uthenga noma uqhuba, ukufinyelela ama-tamper afanele kungaba nomthelela omkhulu ezingeni nasekugcineni kwezakhiwo ezakhiwe.
