Njengoko kuqalwe ukuhlaziywa kwesixeko esidala, iipayipu ezintywilisiweyo kunye neepayipu ezenziwe kwangaphambili ezakhiwa ngeminyaka yoo-1970 kunye noo-1980 ziya kuba zizinto ezibalulekileyo ezichaphazela inkqubela eqhelekileyo yokwakha. Ukuphathwa kweepayipu zesiseko ezazikho ekuqaleni kuye kwaba ngumxholo obalulekileyo kwicandelo lokwakhiwa kwe-geotechnical. Indlela yokwakha yeSuper Top ibonelela ngendlela entsha nesebenzayo yonyango.
Indlela yokwakha yeSuper Top (indlela yokubhoboza intsimbi ejikelezayo) yi-casing rotator esebenzisa uxinzelelo olusezantsi kunye ne-torque eveliswa zizixhobo ezijikelezileyo ezipheleleyo ukuqhuba i-casing yentsimbi ukuba ijikeleze, isebenzisa isenzo sokusika sentloko yokusika enamandla aphezulu kwindawo yombhobho emhlabeni, ibhoboze i-casing emhlabeni, ize isebenzise uzipho lokubamba ukususa imiqobo engaphakathi kwi-casing.
Iindlela eziphambili zokunyanga isiseko esikhoyo ngale sixhobo zezi zilandelayo:
Indlela yoku-1: Sebenzisa esi sixhobo ukugquma isiseko esikhoyo kumbhobho, uze usebenzise isando esinzima ukusiqhekeza, uze ekugqibeleni usebenzise isixhobo sokusibamba ukuze usikhuphe.
Indlela yesi-2: Sebenzisa esi sixhobo ukugquma isiseko esikhoyo kwipayipi, sebenzisa isibhamu samanzi esinoxinzelelo oluphezulu ukutyumza umhlaba ojikeleze inqwaba, uze uqhube i-wedge ende yentsimbi enxantathu ukulungisa inqwaba ekhoyo, ujikeleze i-casing, ujije inqwaba, uze ekugqibeleni usebenzise i-punch kunye ne-stack ukuze ukhuphe icandelo lenqwaba de kugqitywe unyango.
Indlela yesi-3: Ukusebenzisa esi sixhobo, isiseko esikhoyo sigqunywe ngepayiphu, kwaye kufakwa i-multi support shoe crusher kwi-casing. Uxinzelelo loyilo lwesakhiwo lwe-multi support shoe lusetyenziselwa ukufunxa eludongeni lwangaphakathi lwe-casing. Emva koko, i-casing rotary down pressure isetyenziselwa ukuqhuba i-multi support shoe crusher ukuba ibhoboze kwaye iphule inqwaba.

Le ndlela yokwakha yaziwa ngokuba yi "universal construction method" eJapan. Ezi zixhobo zinokufikelela kwi-1/500 verticality kwaye zinokusika amatye aqinileyo kunye nekhonkrithi eqinisiweyo, zibonelela ngezisombululo ezintsha kwiingxaki ezintsha ezidibana nazo kulwakhiwo lwe-geotechnical.
