I-PDC HDD (I-Horizontal Directional Drilling) Izingcezu Zokubhoboza
umkhiqizo Incazelo
Lezi zingcezu ze-HDD cishe ezingabhubhi kanye nezinto ezifakiwe zingamelana nazo zonke izindawo ezinzima namapeshi amabi ongajikijelwa ngawo ukubhola. Kungakhathaliseki ukuthi umba amatshe noma ukungcola, i-Grand Construction ine-drill bitana efanele noma ifakele iphrojekthi yakho.
Izingcezu zokubhoboza ze-PDC HDD zingakwazi ukubhola uhlaka oluqinile oluphakathi nendawo ukuya kwelimaphakathi. Kuyatuswa ukubhoboza i-shale, i-mudstone, i-Cemented Sandstone kanye nedwala le-carbonate elinamandla amaphakathi okucindezela. Sinokukhethwa okukhulu kwezingcezu zokubhoboza ze-HDD, njengezingcezu zomshayeli we-milled-tooth zokwakheka okuthambile nokuxekethile. Ngokuvikelwa komugqa okuthuthukisiwe, insimbi eqinile ku-bevel kanye nokukhishwa kwekhoni yangaphakathi, izingcezu zomshayeli zingakwazi ukumelana nezimo ezinzima zokumba ezivame ukutholwa ezinhlelweni ze-HDD.
Enye yezinzuzo ezibalulekile zezingcezu zethu zokubhoboza i-HDD amandla azo akhethekile okuqondisa, azivumela ukuthi zizulazule ngokunembile ngisho nezinhlelo zokusebenza zokubhola eziyinselele eziyinselele. Kungakhathaliseki ukuthi ubhola ngaphansi komgwaqo wedolobha noma ngaphansi komfula, ungathembela kumabhithi ethu okubhola e-HDD ukuletha ukusebenza okunembayo, okuthembekile ngaso sonke isikhathi.
Ngokungeziwe emandleni azo okusika nokuqondisa, Izingcezu zethu Zokubhoboza Ezivundlile nazo ziklanyelwe ukunciphisa ukudlidliza nokunciphisa ukuguga nokudabuka emishinini yakho yokumba, esiza ukwandisa isikhathi sokuphila kwamathuluzi akho nokunciphisa isikhathi sokuphumula kumaphrojekthi akho okumba.
Ngokungafani namabhithi ajwayelekile aqondiswa yi-PDC, izingcezu zethu ze-Grand Construction zinikeza izinzuzo eziningi zokuklama, okuhlanganisa:
Idizayini yephrofayili eyandisiwe yokumba ngokushesha ekwakhekeni kwamadwala.
Izinzinzisi ezakhelwe ngaphakathi zokuzinza okuthuthukisiwe kwekholomu yokubhoboza.
Amathuluzi amaningi e-PDC empilo ende kunamabhithi okubhola ajwayelekile e-PDC.
Amabhithi ethu ajwayelekile aqondiswa nge-HDD atholakala ngosayizi ongu-5-1/2" no-6-1/2". Ibhithi ngalinye lifaka idizayini yethu yama-5-blade ehlala isikhathi eside futhi ehlonishwa kakhulu, okuhlanganisa ithuluzi le-PDC elingu-13mm, ukuze lisebenze ngobungcweti, elinembe futhi lisebenze kahle kunoma iyiphi iphrojekthi yokumba amatshe.
