中文Indlela yolwakhiwo olujikelezayo kunye nolugcweleyo lubizwa ngokuba yi-SUPERTOP eJapan. I-Steel casing isetyenziselwa ukukhusela udonga ngexesha lenkqubo yokubumba umngxuma. Ineempawu zomgangatho olungileyo wemfumba, akukho ngcoliseko lodaka, umsesane oluhlaza, kunye nokuncipha komlinganiso wokuzalisa ikhonkrithi. Iyakwazi ukusombulula ngokufanelekileyo iingxaki zokuwa komngxuma, ukucutheka kwentamo, kunye nokuzaliswa okuphezulu komlinganiso okwenzekayo xa iindlela eziqhelekileyo zisetyenziselwa ukwakhiwa kweemfumba kwindawo yokuzalisa idolophu kunye ne-karst landforms.
Ukwemba amatye
I-drill ejikelezayo epheleleyo inetorque eyomeleleyo, amandla okungena kunye nentloko yokusika, enokuthi igqibezele imisebenzi yolwakhiwo kulwakhiwo oluqinileyo. Ubulukhuni belitye obunokugrunjwa bunokufikelela: amandla acinezelayo angenawo uniaxial 150-200MPa; ngenxa yokusebenza kwayo ngokugqibeleleyo kokusika, isetyenziswe ngokubanzi ekusikeni: iibhloko zekhonkrithi, iibholiti zamandla aphezulu, ii-H piles, iipilisi zepayipi zensimbi kunye nokunye ukwakhiwa kokucoca.
Ulwakhiwo lwemfumba olufakwe kwimiqolomba
Izixhobo zokugaya ezijikelezayo ngokupheleleyo zineenzuzo ezingenakulinganiswa ekwakhiweni komqolomba ngaphezu kwezinye iinkqubo zokwakha: azifuni ukubuyisela umva kwamatye okanye i-casing eyongezelelweyo. Ngomsebenzi wayo olungileyo wokuhlengahlengisa ngokuthe nkqo, ukusebenza kokulawula okuzenzekelayo kwesantya sokomba, uxinzelelo lokomba, kunye netorque, inokugqiba ngokulula umsebenzi wokomba emqolombeni. Xa ugalela ikhonkrithi emqolombeni, uyenziwa kwi-casing, kwaye ikhonkrithi kunye nokongezwa kwe-arhente yokumisa ngokukhawuleza akulula ukulahlekelwa. Kwaye ngenxa yokuba isixhobo sokomba sinamandla amakhulu okutsala, sinokulibazisa ukutsala. Ke ngoko, inokugqiba kakuhle umsebenzi wokwakha iimfumba ezifakwe emqolombeni.
Ukuchaneka okuphezulu okuthe nkqo
Iyakwazi ukufezekisa ukuchaneka okuthe nkqo kwe-1/500 (i-rotary drilling rigs inokufikelela kwi-1/100), enye yeenkqubo zesiseko semfumba ngokuchaneka okuphezulu okuphezulu kwihlabathi.
1. Ulungelelwaniso lomatshini wokwakha imfumba ejikelezayo epheleleyo
Izixhobo eziphambili kunye namacandelo:
1. Umbhobho ojikelezayo ojikelezayo: ukwenza umngxuma
2. Isingxobo sentsimbi: ukhuseleko eludongeni
3. Isitishi samandla: sibonelela ngamandla enjini ejikelezayo epheleleyo
4. Ifolokhwe yokuphendula: ibonelela ngamandla okumelana nokuthintela i-injini ephambili ekutshintsheni ngexesha lokujikeleza okujikelezayo
5. Igumbi lokusebenza: iqonga lokusebenza, indawo yokusebenza yabasebenzi
Izixhobo ezincedisayo:
1. I-Rotary drilling rig okanye ukubamba: ukukhutshwa komhlaba, ukungena kwamatye, ukucocwa komngxuma
2. Umatshini wokukhupha umbhobho: ukukhutshwa kombhobho, ukujikeleza okupheleleyo ukwenza umsebenzi wokuhamba
3. I-crawler crane: ukuphakamisa umatshini oyintloko, isikhululo samandla, ifoloki yokusabela, njl.; ukubonelela ngenkxaso yefolokhwe yokusabela; ukuphakamisa i-cage yensimbi, i-concrete conduit, ukubamba umhlaba, njl.;
4. I-Excavator: ukulinganisa isayithi, ukucima i-slag, njl.
二.Inkqubo yokwakhiwa kwemfumba yentsimbi ejikelezayo epheleleyo
1. Ukulungiselela ukwakhiwa
Umsebenzi ophambili wokulungiselela ukwakhiwa kukulinganisa indawo. Ekubeni i-drilling rig inkulu kwaye inezixhobo ezininzi ezincedisayo ezinxulumene nazo, kukho iimfuno ezithile zokufikelela kumajelo kunye namaqonga omsebenzi. Ke ngoko, ukulungiswa kolwakhiwo kufuneka kuthathelwe ingqalelo imijelo yokwakha kunye neenqwelo moya ezifunekayo kwimisebenzi efana nemfumba yesiseko sentsimbi yokusetyenzwa kunye nokuveliswa, ukuthuthwa kwe-slag, ukuphakanyiswa kwentsimbi yentsimbi kunye nofakelo, kunye nokugalela isiseko sekhonkrithi.
2. Umlinganiselo kunye noyilo
Okokuqala, qwalasela ngokucophelela ulungelelwaniso, ukuphakama kunye nolunye ulwazi olufanelekileyo olunikezwa yimizobo yoyilo. Emva kokuqinisekisa ukuba zichanekile, sebenzisa isikhululo sisonke ukubeka indawo yemfumba. Emva kokuba iziko lemfumba libekiwe, krwela umgca onqamlezayo ecaleni kweziko lengqumba ukuya kwi-1.5m kude kwaye wenze uphawu lokukhusela imfumba.
3. Injini ejikelezayo epheleleyo kwindawo
Emva kokuba inqaku likhutshiwe, phakamisa i-chassis ejikelezayo ngokupheleleyo, kwaye umbindi we-chassis kufuneka uhambelane nombindi wemfumba. Emva koko phakamisa injini ephambili, uyifake kwi-chassis, kwaye ekugqibeleni ufake ifolokhwe yokusabela.
4. Phakamisa kwaye ufake i-casing yentsimbi
Emva kokuba injini ephambili isendaweni, phakamisa kwaye ufake i-casing yentsimbi.
5. Ukulinganisa kunye nokulungelelanisa ukuqina
Emva kokuba umatshini wokugaya i-rotary usendaweni, yenza i-rotary drilling, kwaye ucinezele i-casing ngelixa ujikeleza ukuqhubela i-casing, ukwenzela ukuba i-casing ifakwe ngokukhawuleza kwi-formation. Xa ugrumba i-casing yentsimbi, sebenzisa i-plumb line ukulungisa ukuthe nkqo kwe-casing kwiindlela ze-XY.
6. Ukwemba i-Casing kunye nokutsalwa komhlaba
Ngelixa i-casing yombiwa emhlabeni, i-crane isetyenziselwa ukukhulula i-emele yokubamba ecaleni kodonga lwangaphakathi lwe-casing ukuya ezantsi komngxuma ukukhupha umhlaba ngokubamba okanye ukusebenzisa i-rotary drilling rig ukukhupha umhlaba.
7. Ukwenziwa kunye nokufakwa kwe-cage yensimbi
Emva kokugrumba ukuya kwindawo ephakanyisiweyo, coca umngxuma. Emva kokuphumelela ukuhlolwa kunye nokwamkelwa ngumhlaba, ukulawulwa kunye neParty A, faka i-cage yensimbi.
8. Ukugalelwa kwekhonkrithi, ukutsalwa kwecasing, kunye nokugalelwa kwemfumba
Emva kokuba i-cage yensimbi ifakwe, uthele ikhonkrithi. Emva kokuba ikhonkrithi igalelwe ukuphakama okuthile, khupha i-casing. I-casing inokutsalwa ngaphandle usebenzisa umatshini wokutshiza umbhobho okanye umatshini oyintloko wokujikeleza ngokupheleleyo.
三,. Izinto eziluncedo kulwakhiwo olujikeleza ngokupheleleyo:
I-1 inokusombulula ukwakhiwa kweemfumba kwiindawo ezikhethekileyo, iimeko ezikhethekileyo zokusebenza kunye ne-strata eyinkimbinkimbi, ngaphandle kwengxolo, akukho vibration kunye nokusebenza okuphezulu kokhuseleko;
I-2 Ayisebenzisi udaka, indawo esebenzayo icocekile, inokuphepheka ukuba kunokwenzeka ukuba udaka lungene kwikhonkrithi, olunceda ekuphuculeni ukuqina kwebhondi yekhonkrithi kwiintsimbi zetsimbi; ikhusela umva komhlaba, ayikhuphi udonga lomngxuma xa uphakamisa i-drill kunye nokunciphisa i-cage yensimbi, kwaye ine-debrilling encinci;
3 Xa kusakha i-drilling rig, inokugweba ngokufanelekileyo i-stratum kunye neempawu zamatye;
4 Isantya sokomba siyakhawuleza, esinokufikelela malunga ne-14m/h kumaleko omhlaba jikelele;
5 Ubunzulu bokomba bukhulu, kwaye ubunzulu obukhulu bungafikelela malunga ne-80m ngokweemeko zomaleko womhlaba;
6 Ukuma komngxuma kulula ukukuqonda, kwaye ukuphakama kunokuchaneka ukuya kwi-1/500;
I-7 Akulula ukuvelisa ukudilika komngxuma, umgangatho womngxuma uphezulu, umzantsi ucocekile, isantya sikhawuleza, kwaye intlenga inokucocwa ukuya kwi-30mm;
8 Ububanzi bomngxuma busemgangathweni kwaye i-coefficient yokuzalisa incinci. Xa kuthelekiswa nezinye iindlela zokubumba umngxuma, umthamo omkhulu wekhonkrithi unokugcinwa.
Umngxuma wokugrumba ojikelezayo uye wawa kakhulu ngenxa yomaleko womhlaba wokuzaliswa ngasemva ubutyebe kakhulu kwaye unamatye amakhulu.
Isiphumo sokwenza umngxuma wecasing epheleleyo
Iirigi zokugrumba ezijikelezayo azisetyenziswanga kuphela kulwakhiwo lwesiseko semfumba kwiistrata ezahlukeneyo ezintsonkothileyo ezifana ne-quicksand, i-karst landforms, kunye ne-backfill ephezulu kakhulu, kodwa inokusetyenziselwa ulwakhiwo lwemfumba yokuluma, iintsika zentsimbi zikaloliwe, kunye nokususwa kwemfumba.
