Indlela ukukhetha sokuprakthiza ngezibhakela

Eyokuqala isando kagesi wabonakala ngo-1932, futhi lokhu naphezu kweqiniso lokuthi sikakhokho walo yadalwa 1851. Kodwa hhayi iphuzu, nje punchers eminyakeni yamuva ube owande kakhulu insimbi. Lokhu cishe njalo umndeni, ngoba iyithuluzi elibalulekile lapho sifeza noma isiphi uhlobo ukulungisa. Kodwa ukuze ube ukulungele ukusebenza nganoma isiphi isikhathi, kudingeka zinakekele Ukukhetha izingxenye ingxenye. Manje sizoxoxa kanjani ukukhetha sokuprakthiza ilungelo ngezibhakela.

Ngaleso sikhathi samanje, baye basakaza kuzo zonke izinhlobo ezintathu izingxenye ezifana. Lokhu perforating sokuzivivinya ngoba SDS + futhi SDS Max, kodwa futhi entsha ngokuphelele, ngakho-ke, akukhona ethandwa kangaka SDS-phezulu. Nakuba kusengaphambili Kuyaphawuleka ukuthi onjiniyela ucabanga ukuthi leli sokuprakthiza engcono ukudala izimbobo-25 mm. Ngokuqondene nabantwana bami ababili bokuqala ongakhetha, basuke ikakhulu libhekene lwemidlalo yabo design futhi ubukhulu bayo esiphezulu. Iqiniso ukuthi SDS + - ke sokuzivivinya ngoba izando, nge isisindo ingqikithi amakhilogremu abafinyelela kwabahlanu. Kodwa SDS Max isivele eyenzelwe amathuluzi esindayo.

By endleleni, uma uthanda, ungathola adaptha akhethekile zisebenzisa SDS Max ku imishini ukukhanya, futhi SDS + - okunalokho ku esindayo. Nokho, akukho okuhle ngeke kuholele. Esimweni sokuqala kuzokhulisa bafake phezu isibhamu, kanti eyesibili - bafake we sokuprakthiza. Bobabili izinketho alilihle.

Uma ukhetha sokuprakthiza Punch, into yokuqala kufanele sinake kodaka yayo ukususwa. Okwamanje, kule umbandela, borax zingahlukaniswa zibe izinhlobo ezintathu: i-engela encane, ephezulu engela kanye isikulufa. Kwemisebenzi yoMnyango ukubonwa uyisabelo zokugcina - isikulufa. Iqiniso ukuthi uyakwazi ukunikeza ukususwa kakhulu okusheshayo sludge, okuyinto ziwusizo ngokukhethekile lapho Drilling izimbobo ejulile. Kodwa-ke kumele ngokucophelela kwasuka ahlabayo anemifantu ejulile yayisetshenziswa.

Manje uthinte ohlangothini kwezomnotho mayelana nodaba. Eshibhe ngeke sokuprakthiza ngezibhakela, njengokungathi efakwe ohlwini abakhiqizi Chinese noma inkampani yasekhaya. Nokho, ukuthenga imikhiqizo enjalo, kubalulekile ukubala kusengaphambili fragility yayo. Ngaphezu kwalokho, sokuzivivinya ezishibhile kungukuthi njalo esenziwe ngokuhambisana nale mithetho. Nokho, ungakwazi ukuncika okuthile okuhlukile. Kungenzeka ukuthi lokhu sokuprakthiza eyokusiza nganoma yisiphi unyaka owodwa. Kodwa lokhu okuhlukile, okuyinto akufanele ngempela into nethemba.

Nokho ikhambi engcono kungaba ukusebenzisa imikhiqizo ephuma yesibili intengo - ke sokuzivivinya kusuka abakhiqizi "ngoba i amateur." Ukusebenzisa kwabo cishe ephelele ekhaya.

Nokho, kukhona isigaba sesithathu intengo. Kuyinto augers okhokhelwayo. Bayoba isikhathi eside ngempela, futhi Ukucaciswa yabo zimane ezingeni eliphezulu kakhulu. Nokho, i-ukuthengwa kwezimpahla ezifana kufanele ukwaba ingxenye enkulu izimali.

Njengoba ayezithathele inothi ulwazi olungenhla, siyasibona kakade ngokuphepha uya esitolo bese ukhetha sokuprakthiza efaneleke kakhulu ngesibhamu.
