1. Isishwankathelo seprojekthi
Le projekthi isebenzisa ulwakhiwo oluvulekileyo. Ukuba ubunzulu bomngxuma wesiseko bungaphezulu kweemitha ezi-3 kwaye bungaphantsi kweemitha ezi-5, isakhiwo esixhasayo sixhaswa ludonga olugcina umxhuzulane lwesamente oluyi-φ0.7m*0.5m. Xa ubunzulu bomngxuma wesiseko bungaphezulu kweemitha ezi-5 kwaye bungaphantsi kweemitha ezili-11, kusetyenziswa inqwaba ebolileyo ye-φ1.0m*1.2m + umqolo omnye we-φ0.7m*0.5m. Ubunzulu bomngxuma wesiseko bungaphezulu kweemitha ezili-11, kusetyenziswa inqwaba ebolileyo ye-φ1.2m*1.4m + umqolo omnye we-φ0.7m*0.5m.
2. Ukubaluleka kolawulo oluthe nkqo
Ulawulo lokuma kweenqwaba lubaluleke kakhulu ekwakhiweni komngxuma wesiseko olandelayo. Ukuba ukuphambuka okuthe nkqo kweenqwaba ezibhoboziweyo ezijikeleze umngxuma wesiseko kukhulu, kuya kukhokelela ekuxinezelekeni okungalinganiyo kwesakhiwo sokugcina esijikeleze umngxuma wesiseko, kwaye kuzise iingozi ezinkulu ezifihlakeleyo kukhuseleko lomngxuma wesiseko. Kwangaxeshanye, ukuba ukuphambuka okuthe nkqo kwenqwaba ebhoboziweyo kukhulu, kuya kuba nefuthe elikhulu ekwakhiweni nasekusetyenzisweni kwesakhiwo esiphambili kwixesha elizayo. Ngenxa yokuphambuka okukhulu kokuma kwenqwaba ebhoboziweyo ejikeleze isakhiwo esiphambili, amandla ajikeleze isakhiwo esiphambili aya kungalingani, okuya kukhokelela kwiintanda kwisakhiwo esiphambili, kwaye kuzise iingozi ezifihlakeleyo ekusetyenzisweni okulandelayo kwesakhiwo esiphambili.
3. Isizathu sokuphambuka kokuma nkqo
Ukuphambuka okuthe nkqo kwenqwaba yovavanyo kukhulu. Ngokuhlalutywa kweprojekthi yokwenyani, ezi zizathu zilandelayo zishwankathelwe ukusuka ekukhethweni koomatshini ukuya ekwakhiweni komngxuma wokugqibela:
3.1. Ukukhethwa kwee-drill bits, ubulukhuni be-geological bomatshini wokumba ii-pile ezijikelezayo kwinkqubo yokumba ayifani, ukukhethwa kwee-drill bits akunakuhlangabezana neemfuno zeemeko ezahlukeneyo ze-geological, nto leyo ebangela ukuphambuka kwee-bit, kwaye ukuphambuka ngokuthe nkqo kwe-pile akuhlangabezani neemfuno zenkcazo.
3.2. Isilinda yokukhusela ifihliwe endaweni yayo.
3.3. Ukugutyungelwa kombhobho wokugrumba kwenzeka ngexesha lokugrumba.
3.4. Indawo ebekwe kuyo ikheyiji yentsimbi ayisebenzi kakuhle, ngenxa yokubekwa ngendlela engafanelekanga kwephedi yokulawula ikheyiji yentsimbi, ukuphambuka okubangelwa kukungaphumeleli ukujonga iziko emva kokuba ikheyiji yentsimbi isendaweni, ukuphambuka okubangelwa kukutyibilika kwekhonkrithi ngokukhawuleza okanye ukuphambuka okubangelwa ngumbhobho oxhoma ikheyiji yentsimbi.
4. Amanyathelo okulawula ukuphambuka ngokuthe nkqo
4.1. Ukukhethwa kwe-drill bit
Khetha ii-drill bits ngokweemeko zokwakheka:
1. Udongwe: Khetha isiseko esinye sebhakethi yokubhola ejikelezayo, ukuba ububanzi buncinci ungasebenzisa iibhakethi ezimbini okanye ibhakethi yokubhola eneepleyiti zokukhulula umthwalo.
②Idaka, umaleko womhlaba ongaqinanga, umhlaba onesihlabathi, umaleko welitye elincinane elidityanisiweyo kakuhle nobukhulu obuncinci bamasuntswana: khetha ibhakethi yokugrumba engaphantsi kabini.
1. Udongwe oluqinileyo: khetha indawo yokungena enye (engaphantsi enye nembini inokuba) ibhakethi yokumba ejikelezayo, okanye amazinyo ebhakethi ajijekileyo.
Igrabile eqinisiweyo kunye namatye agutyungelwe ngamandla: kufuneka ixhotyiswe nge-conical spiral drill bit kunye ne-double-bottom drilling bucket (enobubanzi obunye bobukhulu be-particle enkulu, enobubanzi obuphindwe kabini)
⑤ilitye elijikelezileyo: lixhotyiswe nge-cylindrill core bit – i-conical spiral drill – ibhakethi yokubhola ejikelezayo ephindwe kabini, okanye i-spiral bit ethe tye – ibhakethi yokubhola ejikelezayo ephindwe kabini.
⑥Ilitye elinomoya obandayo: lixhotyiswe nge-cone cone core drill bit – i-conical spiral drill bit – ibhakethi yokubhola ejikelezayo ephindwe kabini ukuba ububanzi bukhulu kakhulu ukuba bufikelele kwinkqubo yokubhola eqongeni.
4.2. Ibhokisi igqunyiwe
Ukuze kugcinwe ukuma nkqo kwesilinda esikhuselayo xa kugqunywa isilinda esikhuselayo, ulawulo lokudibana kufuneka lwenziwe ngomgama owahlukileyo ukusuka kwinqwaba ekhokelayo ukuya kwiziko lenqwaba de umphezulu wesilinda esikhuselayo ufikelele kwindawo echaziweyo. Emva kokuba isilinda sigqunywe, indawo ephakathi yenqwaba iyabuyiselwa ngolu mgama kunye necala elichazwe ngaphambili, kwaye kufunyaniswa ukuba umbindi wesilinda uhambelana nombindi wesilinda, kwaye ulawulwa ngaphakathi koluhlu lwe-±5cm. Kwangaxeshanye, ujikelezo lwesilinda luyaxinwa ukuqinisekisa ukuba luzinzile kwaye aluyi kususwa okanye ludilike ngexesha lokugrumba.
4.3. Inkqubo yokugrumba
Inqwaba ebotshiweyo kufuneka ibholwe kancinci emva kokuvula umngxuma, ukuze kwenziwe ukhuselo oluhle noluzinzileyo eludongeni kwaye kuqinisekiswe indawo efanelekileyo yomngxuma. Ngexesha lenkqubo yokubhoboza, indawo yombhobho wokubhoboza ijongwa rhoqo nge-intersection yomgama, kwaye ukuphambuka kulungiswa ngoko nangoko de kube indawo yomngxuma imiselwe.
4.4. Ukubekwa kwekheyiji yentsimbi
Ukufunyanwa kokuphambuka kwengqimba yenqwaba kugqitywa kukuphambuka phakathi kombindi wekheyiji yentsimbi kunye nombindi wekheyiji eyilwe, ngoko ke indawo ebekwe kuyo ikheyiji yentsimbi yinto ebalulekileyo ekulawuleni ukuphambuka kwesikhundla senqwaba.
(1) Kusetyenziswa iibhari ezimbini zokuxhoma xa ikheyiji yentsimbi ibekwe phantsi ukuqinisekisa ukuba ikheyiji yentsimbi imile nkqo emva kokuphakanyiswa.
(2) Ngokweemfuno zekhowudi, kufuneka kongezwe iphedi yokukhusela, ingakumbi kwindawo ephezulu yenqwaba kufuneka kongezwe iphedi yokukhusela.
(3) Emva kokuba ikheyiji yentsimbi ibekwe emngxunyeni, tsala umgca onqamlezileyo ukuze ubone indawo esembindini, uze emva koko wenze umgama phakathi kombindi wendawo yokuhlangana kunye nokubuyiselwa kwenqwaba ngokuzoba inqwaba kunye necala elibekiweyo. Thelekisa umgca othe nkqo oxhonyiweyo nombindi wekheyiji yentsimbi, kwaye ulungise ikheyiji yentsimbi ngokushukumisa kancinci ikreyini ukuqinisekisa ukuba amaziko amabini ayahambelana, uze udibanise i-positioning bar ukuze wenze i-positioning bar ifikelele eludongeni lwesilinda esikhuselayo.
(4) Xa ikhonkrithi egalelweyo ikufutshane nekheyiji yentsimbi, yehlisa isantya sokugalelwa kwekhonkrithi kwaye ugcine indawo ye-catheter embindini womngxuma.
