Isixhobo sokugrumba esijikelezayo esibuyela umvayirobhothi yokugrumba ejikelezayo. Ifanelekile ekwakheni iindawo ezahlukeneyo ezintsonkothileyo ezifana nesanti ekhawulezayo, i-silt, udongwe, ilitye elincinci, umaleko wegrabile, amatye agugileyo, njl.njl., kwaye isetyenziswa kakhulu ekwakhiweni kwezakhiwo, iibhulorho, ukugcinwa kwamanzi, imithombo yamanzi, umbane, unxibelelwano, ukuhla kwamanzi ngobunjineli kunye nezinye iiprojekthi.
Umgaqo wokusebenzaisixhobo sokugrumba esijikelezayo:
Isixhobo sokubhola esibizwa ngokuba yi-reverse circulation sithetha ukuba xa sisebenza, i-rotary disc iya kuqhuba i-drill bit ukuze isike kwaye iphule ilitye nomhlaba emngxunyeni, ulwelo lokuhluza luya kugeleza luye ezantsi komngxuma ukusuka kumngxunya ojikelezayo phakathi kombhobho wokuhluza kunye nodonga lomngxuma, lupholise i-drill bit, luthwale i-slag yokuhluza ilitye kunye nomhlaba enqunyulweyo, kwaye lubuyele emhlabeni ukusuka kumngxunya wombhobho wokuhluza. Kwangaxeshanye, ulwelo lokuhluza luya kubuyela emngxunyeni ukuze lwenze umjikelo. Njengoko ububanzi bomngxunya wangaphakathi wombhobho wokuhluza buncinci kakhulu kunobo bomngxunya ophakathi, amanzi odaka kumbhobho wokuhluza anyuka ngokukhawuleza kakhulu kunokujikeleza okuqhelekileyo. Ayingomanzi acocekileyo kuphela, kodwa ikwanokuzisa i-slag yokuhluza phezulu kombhobho wokuhluza kwaye igeleze kwitanki yokuhluza udaka, apho udaka lunokuphinda lusetyenziswe emva kokucocwa.
Umgaqo kukufaka umbhobho wokugrumba emngxunyeni ozaliswe lulwelo lokugungxula, kwaye ngokujikeleza kwetafile ejikelezayo, qhuba intonga yokudlulisa umoya eqinileyo kunye ne-drill bit ukuze ujikeleze kwaye usike ilitye nomhlaba. Umoya ocinezelweyo utshizwa kwi-nozzle esezantsi kombhobho wokugrumba, wenze umxube wodaka, isanti, amanzi kunye negesi elula kunamanzi kumbhobho wokugrumba kunye nomhlaba kunye nesanti ezisikiweyo. Ngenxa yesiphumo esidibeneyo somahluko woxinzelelo phakathi kwangaphakathi nangaphandle kombhobho wokugrumba kunye nomfutho woxinzelelo lomoya, umxube wegesi yamanzi esanti yodaka uya kunyuka kunye nolwelo lokugrumba, kwaye uya kukhutshelwa kwidama lodaka lomhlaba okanye itanki yokugcina amanzi ngepayipi yoxinzelelo. Umhlaba, isanti, ilitye elimdaka kunye nelitye elimdaka liya kuhlala edamini lodaka, kwaye ulwelo lokugrumba luya kuphuma luye emngxunyeni kwakhona.
Iimpawu zeisixhobo sokugrumba esijikelezayo esibuyela umva:
1. I-drill yokujikeleza umva ixhotyiswe ngengalo yoomatshini enepayipi yokubhola, engasetyenziswa kwimingxunya ethe tye kunye neemeko ze-vertex encinci. Kwangaxeshanye, i-rig yokubhola ikwaxhotyiswe nge-winch ye-hydraulic encedisayo, enciphisa kakhulu amandla abasebenzi babasebenzi bomatshini, kwaye ilungele ukwakhiwa komatshini okukhuselekileyo nokuphucukileyo.
2. Isixhobo sokugrumba sithatha isixhobo sobunjineli sokukrumba kunye nesixhobo sokuhamba nge-hydraulic, esilungele ukushukunyiswa kwaye sifanelekile ngakumbi kwiindawo ezithe tyaba, iintaba, iinduli kunye nezinye iindlela zomhlaba. Isixhobo sokugrumba sixhotyiswe ngee-outriggers ezi-4, ngoko isixhobo sokugrumba asinakungcangcazela kakhulu kwaye sizinzile kakuhle ngexesha lokwakhiwa kwesixhobo sokugrumba.
3. Isixhobo sokugrumba esijikelezayo siqhutywa ngamandla ombane, nomsindo ophantsi kunye nongcoliseko, ukusebenza kakuhle okuphezulu kunye ne-coefficient enkulu yokugcina amandla.
4. Isixhobo sokugrumba esijikelezayo sisebenza ngeendlela ezininzi, kwaye zonke izinto eziphambili ziimveliso ezingabizi kakhulu. Inkqubo ixhotyiswe ngezixhobo zokukhusela uxinzelelo kunye nezixhobo ze-alamu.
5. Izibambo kunye nezixhobo zazo zonke ii-actuators ze-reverse circulation drilling rig zibekwe kwiqonga lokusebenza, elilungele kwaye lithembekile ekusebenzeni nasekulawuleni.
6. Isixhobo sokugrumba esijikelezayo sisebenzisa isakhelo sokugrumba esahlukileyo. Inkqubo yokugrumba inkulu, ukumelana nokugoba kukhulu, isakhiwo silula, ukugcinwa kulula, ukufuduka kulula, ukusebenza kwe-orifice kulula, kwaye ukugrumba i-angle enkulu ye-vertex kunokwakhiwa.
7. Isixhobo sokugrumba esijikelezayo esibuyela umva sisebenzisa intloko enkulu yamandla enomsebenzi wokuxhathisa impembelelo enkulu. Isantya sokujikeleza sifanelekile kwiimfuno zokujikeleza komoya okubuyela umva. Amandla okuphakamisa, i-torque kunye nezinye iiparameter zinokuhlangabezana neemfuno zomgqomo we-DTH ojikelezayo ongaphantsi kwe-100M kunye nezinye iimfuno zenkqubo.
