Kuyobora Diameter + Yahinduwe Diameter + Ubwoko bwa Shank

Gufungura umwobo wa PLATO DTH birashobora gutanga kwaguka kumwobo kubintu bitandukanye bikenerwa no gucukura inyundo zikenewe, impamvu ziva mubucukuzi nubushobozi bwibikoresho kugeza aho akazi gakorerwa hamwe nibisobanuro byakazi. Mubyongeyeho, Gufungura umwobo wa Acedrills biraboneka mubishushanyo bitandukanye, buri kimwe gishobora kuba kibereye porogaramu zimwe. Iki gikoresho gikoreshwa muburyo bukoreshwa mu nganda kugirango habeho umwobo munini wa diameter.

Gufungura umwobo ni imyitozo yihariye ishobora gukoreshwa mu kwagura ubunini bwabayeho mbere. Mugihe runaka cyakazi birashobora kuba ngombwa kongera ubunini bwumwobo wabanje gucukurwa kugeza kuri diameter nini cyangwa gucukura umwobo munini wa diameter. Gufungura ibyobo byateguwe kubwiyi ntego, nuburyo bwiza bwo kwagura umwobo, bityo bits yitwa "Gufungura Hole". Imyitozo isanzwe ikubiyemo gucukura umwobo muto ugereranije nicyiciro cya mbere, nicyiciro cya kabiri nicyanyuma hanyuma ukarushaho kwaguka hamwe nu gufungura umwobo, kubera ko ibyo bishobora kuvamo umwobo utoroshye kandi bisaba imashini zidafite imbaraga. Kandi ibyiciro bitandukanye birashobora gushyirwaho kubisobanuro byo gucukura kugirango bigabanuke gukata no kuvanaho, hamwe nubushobozi bwa rig. Uretse ibyo, kuzunguruka kwizuba, gufungura umwobo wa DTH birimo imbaraga zinyeganyega zigira ingaruka kumutwe wimyitozo mu rutare cyangwa izindi substrate. Igikorwa kigira ingaruka zirashobora guhindagura urutare kandi nanone kigahata inyuma no hejuru, gifasha gusiba umwobo. Noneho, usibye kwagura umwobo, ufungura umwobo ushobora no guhanagura ibintu birenze.

Gucukura ibyobo binini birasabwa mu nganda nyinshi zitandukanye, nko gushakisha hydrocarubone, gucukura neza, no gucukura horizontal kuri tunel nibindi bikorwa nibindi. Gucukura umwobo munini birashobora gusaba imbaraga zidasanzwe hamwe nimashini nini cyane, kuburyo rero inzira rimwe na rimwe bikorwa mubyiciro byinshi. Rimwe na rimwe, ingano ntoya ugereranije izakoreshwa mu gucukura umwobo. Ubu buryo bwo gucukura busanzwe busaba imbaraga nke kuruta kubikora mu ntambwe imwe kandi birashobora no kuvamo umwobo uremereye. Nyuma yo gucukura umwobo wambere wicyitegererezo, hafungura umwobo ushobora kwagura umwobo. Mu bihe nk'ibi, ibisubizo birashobora kuba umwobo wuzuye washyizweho hamwe nibikoresho bidafite imbaraga zirenze uko byari bikenewe kugirango ucukure umwobo munini mugitangira.

Gufungura umwobo wa PLATO DTH biraboneka mumurambararo wahinduwe kuva kuri 130mm kugeza kuri 660mm (5 1/8 ”kugeza 26”) hamwe na shanki yashushanyije kugirango ihuze inyundo zizwi cyane za DTH, kandi zakozwe muburyo butandukanye kugirango zuzuze buri murima wihariye. ibisabwa. Acedrills ikoresha ibyuma byiza gusa mukubyara 'gufungura imyobo nayo, izaguha isaha kumasaha yo gucukura nta kibazo, kandi hamwe nabo uzahora umenya ko byakozwe hamwe nubwiza waje gutegereza. Mubyongeyeho, Acedrills irashobora kandi gukorana nawe mugushushanya umwobo mushya ufungura bito kugirango wongere imikorere mubihe byubutaka uhura nabyo kumurimo wawe nibiba ngombwa.

PLATO iri mumwanya wo guha abakiriya ibice byose byurwego rwibikoresho byo gucukura DTH, harimo inyundo za DTH, bits (cyangwa bits ibikoresho bihwanye) imiyoboro n'intebe zo kumena inyundo nibindi. Ibikoresho byacu byo gucukura DTH nabyo byateguwe neza kandi bikozwe mubucukuzi bwamabuye y'agaciro, inganda zicukura amazi, ubushakashatsi, ubwubatsi nubwubatsi.

Hasi-uburyo bwa mwobo (DTH) bwatunganijwe muburyo bwo gucukura umwobo munini wa diametre hepfo mubikorwa byo gucukura hejuru, kandi izina ryayo ryaturutse kukuba uburyo bwa percussion (inyundo ya DTH) bukurikira bito bikamanuka mu mwobo, aho kuruta kuguma hamwe nibiryo nkabashoferi basanzwe na jackhammers.

Muri sisitemu yo gucukura DTH, inyundo na biti nibikorwa byibanze nibigize, kandi inyundo iherereye inyuma yinyuma ya biti kandi ikorera munsi yumwobo. Piston ikubita hejuru yubuso bwa biti, mugihe inyundo itanga icyerekezo kigororotse kandi gihamye cyimyitozo. Ibi bivuze ko nta ngaruka imbaraga zirekura zinyuze mubice byose mumurongo wimyitozo. Ingaruka zingufu nigipimo cyinjira rero ziguma zihoraho, tutitaye kuburebure bwumwobo. Piston ya drill ikoreshwa numwuka uhumeka utangwa unyuze mu nkoni ku gitutu cyo gutanga kiri hagati ya 5-25 (0.5-2.5 MPa / 70-360 PSI). Moteri yoroheje ya pneumatike cyangwa hydraulic yashyizwe hejuru yubutaka itanga kuzunguruka, kandi gutemagura ibintu bigerwaho numwuka uva mu nyundo haba n'umwuka uhumeka hamwe n'inshinge zatewe n'amazi cyangwa n'umwuka usanzwe wo mu kirombe hamwe n'ikusanyirizo ry'umukungugu.

Imiyoboro ya drill yohereza imbaraga zikenewe zo kugaburira hamwe no kuzunguruka kuri tike yuburyo bwo kugira ingaruka (inyundo) na biti, ndetse no gutanga umwuka ucometse ku nyundo no gukata amashanyarazi kubera ko umwuka wuzuye uhuha umwobo ukawusukura kandi ugatwara ibice hejuru. umwobo. Imiyoboro ya myitozo yongewe kumurongo wimyitozo ikurikiranye inyuma yinyundo uko umwobo ugera kure.

Gucukura DTH nuburyo bworoshye cyane kubakoresha kubucukuzi bwimbitse kandi bugororotse. Mu mwobo uri hagati ya mm 100-254 (4 ”~ 10”), gucukura DTH nuburyo bwiganje bwo gucukura muri iki gihe (cyane cyane iyo ubujyakuzimu burenze metero 20).

Uburyo bwa DTH bwo gucukura buragenda bwiyongera mubyamamare, hamwe no kwiyongera mubice byose byasabwe, harimo guturika-umwobo, iriba ryamazi, umusingi, peteroli na gaze, sisitemu yo gukonjesha no gucukura pompe zo guhanahana ubushyuhe. Kandi porogaramu yaje kuboneka kubutaka, aho icyerekezo cyo gucukura muri rusange kiri hejuru aho kumanuka.

Ibintu nyamukuru nibyiza byo gucukura DTH (cyane ugereranije no gucukura hejuru-inyundo):

1.Urugero runini rw'imyobo, harimo na diameter nini cyane;

2.Umwobo mwiza ugororotse muri 1.5% gutandukana udafite ibikoresho biyobora, byukuri kuruta inyundo yo hejuru, kubera ingaruka ziri mumwobo;

3.Gusukura umwobo mwiza, hamwe numwuka mwinshi wo koza umwobo ku nyundo;

4.Ubuziranenge bwumwobo, hamwe nurukuta rworoshye ndetse n’urwobo rwo kwishyuza byoroshye ibisasu;

5.Ubworoherane bwo gukora no kubungabunga;

6.Imbaraga zogukwirakwiza ingufu hamwe nubushobozi bwo gucukura umwobo muremure, hamwe no guhora byinjira kandi nta gutakaza ingufu mu ngingo zinyuze mu mugozi wimyitozo kuva itangira kugeza irangiye umwobo, kimwe ninyundo yo hejuru;

7.Kora imyanda mike kumanikwa, kumeneka kabiri, gucukura amabuye make na chute kumanikwa;

8.Ibiciro bito ku bikoresho bikoreshwa mu gucukura, kubera umugozi wimyitozo ntibikoreshwa ningufu ziremereye nkuko hamwe no gucukura inyundo zo hejuru hamwe nu mugozi wimyitozo rero biraramba cyane;

9.Kugabanya ibyago byo kugwa mumiterere yamabuye yamenetse kandi afite amakosa;

10.Urwego rwo hasi rw'urusaku ku kazi, kubera inyundo ikora munsi y'umwobo;

11.Ibipimo byinjira byinjira hafi yumuvuduko wumwuka, kubwibyo gukuba kabiri umuvuduko wumwuka bizavamo inshuro ebyiri kwinjira.
