中文Ukujikeleza okugcwele kanye nendlela yokwakha egcwele ngokugcwele ibizwa ngokuthi yi-Supertop Method eJapan. Ukufakwa kwensimbi kusetshenziselwa ukuvikela udonga ngesikhathi senqubo yokwakhiwa komgodi. Inezici zekhwalithi enhle yenqwaba, akukho ukungcoliswa kodaka, indandatho eluhlaza, futhi inciphise ukukhokhiswa kokhonkolo kokugcwaliswa kokhonkolo. Ingaxazulula ngempumelelo izinkinga zokuwa kwe-hole, i-shrinkage yentamo, kanye nokugcwaliswa okuphezulu okwenzeka lapho izindlela ezijwayelekile zisetshenziselwa ukwakhiwa kwenqwaba yendawo yokugcwaliswa kwendawo ephakeme yasedolobheni.
Ukudonsa kwemvula
I-drill ephelele yokujikeleza okugcwele ine-torque eqinile, i-penetation Force kanye nekhanda lokusika, elingaqedela imisebenzi yokwakha ekwakhekeni kwamadwala ama-rock. Ubulukhuni be-rock olungachithwa lungafinyelela: amandla angenangqondo angu-150-200MPA; Ngenxa yokusebenza kwayo kokusika okuphelele, kusetshenziswe kabanzi ekusikeni: Amabhulokhi ukhonkolo, ama-bolts anamandla aphezulu, amaphayiphu we-H, amapayipi ensimbi nokunye ukwakhiwa okucacile.
Ukwakhiwa kwenqwaba ye-Cast-In-File ngemihume
Ama-rig ajikelezayo okujikeleza ngokugcwele anezinzuzo ezingenakuqhathaniswa eCave Construction phezu kwezinye izinqubo zokwakha: azidingi ukubhekelwa kabusha kwamadwala noma ukwengeza okwengeziwe. Ngokusebenza kwayo okulungiselelwe mpo okum mpo, ukusebenza okuzenzakalelayo kokushayela isivinini sokumba, ukumba kwengcindezi, ne-torque, kungaqedela kalula umsebenzi wokumba ngomhume. Lapho uthela ukhonkolo emhumeni, kwenziwa e-COSIng, futhi ukhonkolo ngokufakwa komenzeli osheshayo akulula ukulahlekelwa. Futhi ngoba i-rig evuthayo inamandla okudonsa anamandla, kungabambezeleka futhi ukudonsa. Ngakho-ke, ingaqedela kahle umsebenzi wokwakha wezinqwaba zezindawo eziseduze komhume.
Ukunemba okuphezulu okuphezulu
Kungakufeza ukunemba okuqondile kwama-1/500 (ama-rigs wokushayela ajikelezayo angafinyelela ku-1/11), okungenye yezinqubo zesisekelo sezinqwaba ngokunemba okuphezulu kakhulu emhlabeni.
1. Ukucushwa okugcwele okuvuselelwa kwenqwaba
Imishini eyinhloko nezakhi:
1. I-Rig evukelayo yokuvuselela i-rig: ukwakha umgodi
2. Ukufaka i-Steel: Ukuvikelwa Kodonga
I-3. Isiteshi samandla: Inikeza amandla injini ephelele evuselelwayo
4. Imfoloko Yokuphendula: Inikeza amandla okuphendula ukuvikela injini enkulu kusuka ekushintsheni ngesikhathi sokujikeleza okugcwele
I-5. Igumbi lokusebenza: Ipulatifomu yokusebenza, indawo yokusebenza yabasebenzi
OUSISISI SSISINISISISISISISISISISHINI:
1. I-Rotary Drilling Rig noma ukubamba: Ukukhishwa kwenhlabathi, ukungena kwedwala, ukuhlanza umgodi
2. Umshini wepayipi wepayipi: Ukukhishwa kwamapayipi, ukujikeleza okugcwele ukwakha ukusebenza kokugeleza
3. UCrawler Crane: Ukuphakamisa umshini omkhulu, isiteshi samandla, imfoloko yokuphendula, njll; ukuhlinzeka ukwesekwa kwemfoloko yokuphendula; Ukuphakamisa ikheji lensimbi, inkomba kakhonkolo, inhlabathi ebamba, njll;
4. Excarerator: Ukulinganisa isayithi, ukusula i-slag, njll.
二.Inqubo ephelele yokujikeleza kwensimbi ephelele inqubo yokwakha yenqwaba
1. Ukulungiselela ukwakhiwa
Umsebenzi oyinhloko wokulungiselela ukwakhiwa ukukhulisa isayithi. Njengoba i-rig yokumba inkulu futhi inemishini eminingi ehlobene ehlobene, kunezidingo ezithile zeziteshi zokufinyelela namapulatifomu okusebenza. Ngakho-ke, ukulungiswa kokwakha kudinga ukucubungula iziteshi zokwakha kanye nezindiza zomsebenzi ezidingekayo ukuze kusetshenzwe okufana nokukhiqizwa kwensimbi ye-pile yesisekelo kanye nokukhiqizwa, ukuthutha kwensimbi, ukuthululwa kokhonkolo kwensimbi
2. Ukulinganiswa nokwakheka
Okokuqala, ubuyekeze ngokucophelela izixhumanisi, ukuphakama kanye neminye imininingwane efanelekile enikezwe imidwebo ye-design. Ngemuva kokuqinisekisa ukuthi banembile, sebenzisa isiteshi esiphelele ukubeka isikhundla senqwaba. Ngemuva kokuthi isikhungo se-Pile sikhishwe, dweba umugqa wesiphambano eceleni kwesikhungo se-Pile kuya ku-1.5m kude futhi wenze uphawu lokuvikelwa kwenqwaba.
3. Injini ephelele evuselelayo
Ngemuva kokuthi iphuzu likhishwe, liphakamise i-chassis evuselelayo, futhi maphakathi ne-chassis kufanele ahambisane nendawo enkabeni yenqwaba. Bese uphakamisa injini enkulu, uyifake ku-chassis, bese ekugcineni ufake ifreyimu yokuphendula.
4. Hoost bese ufaka i-casing yensimbi
Ngemuva kokuthi injini eyinhloko isendaweni, iphakamise bese ifaka i-casing yensimbi.
5. Kala futhi ulungise i-verticality
Ngemuva kokuthi umshini wokushayela ejikelezayo usendaweni, yenza ukumba okujikelezayo, bese ucindezela phansi lapho ujikeleza ukushayela i-casing, ukuze i-casing ingahle idonswe ngokushesha ekwakhiweni. Lapho ugaya ukufakwa kwensimbi, sebenzisa umugqa we-plumb ukuze ulungise i-verticality of the casing kwizikhombisi-xy.
I-6
Ngenkathi i-casing idonswa emhlabathini, i-crane isetshenziselwa ukukhipha ibhakede lokubamba odongeni lwangaphakathi lwe-casing ezansi komgodi ukuze ikhiphe inhlabathi noma isebenzisa i-rotary dring rig ukukhipha inhlabathi.
7. Ukufakwa kanye nokufakwa kwekheji lensimbi
Ngemuva kokumba kuya ekuphakameni okwenziwe, hlanza umgodi. Ngemuva kokudlula ekuhlolweni nokwamukelwa nguHlelo Lomhlaba, Ukugadwa kanye nePhathi A, Faka ikheji lensimbi.
8
Ngemuva kokuthi ikheji lensimbi lifakiwe, uthele ukhonkolo. Ngemuva kokuthi ukhonkolo uthululwa ekuphakameni okuthile, khipha i-casing. I-casing ingakhishwa isebenzisa umshini wepayipi wepayipi noma umshini wokujikeleza okugcwele.
三,. Izinzuzo zokwakhiwa okugcwele kokujikeleza:
1 Ingaxazulula ukwakhiwa kwenqwaba kumasayithi akhethekile, izimo ezikhethekile zokusebenza kanye ne-strata eyinkimbinkimbi, ngaphandle komsindo, akukho ukudlidliza nokuPhepha okuphezulu;
2 ayisebenzisi udaka, indawo esebenzayo ihlanzekile, ingakugwema ukuthi kungenzeka ukuthi udaka olungena kukhonkolo, oluvumelana nokwenza ngcono amandla ebhondi kakhonkolo emigoqweni yensimbi; kuvimbela i-backflow yenhlabathi, ayiklibhula udonga lomgodi lapho uphakamisa ukumba bese wehlisa ikheji lensimbi, futhi unemfucumfucu enganciphisi;
3 Lapho kwakhiwa i-rig evuthayo, kungahlulela kahle izici ze-stratum nezamatshe;
4 Ijubane lokumba liyashesha, elingafinyelela cishe ngo-14m / h kwezingqimba zenhlabathi ejwayelekile;
5 Ukujula kokumba kukhulu, futhi ukujula okuphezulu kungafinyelela cishe ngo-80m ngokuya ngezimo zenhlabathi;
6 IVerticality of the hole kulula ukuyiqonda, futhi i-verticality ingaba ne-1/500;
7 Akulula ukukhiqiza ukuwa komgodi, ikhwalithi yembobo iphakeme, phansi kuhlanzekile, ijubane liyashesha, futhi i-sediment ingasulwa cishe ku-30mm;
8 Ububanzi bembobo bujwayelekile futhi i-coeffing egcwalisa incane. Uma kuqhathaniswa nezinye izindlela zokwakha, inani elikhulu lekhonkolo lingasindiswa.
I-Rotary Drilling Hole yawa ngokungathi sína ngenxa yesendlalelo senhlabathi sangemuva sikhulu kakhulu futhi inamadwala amakhulu.
Umphumela owakha umgodi wokufaka okugcwele
Ama-rig ajikelezayo ajikelezayo awasetshenziswa kuphela ukwakhiwa kwesisekelo sezinqwaba ze-strata ehlukahlukene njenge-QuickSand, iKarst Landform, futhi ingasetshenziselwa ukugcwaliswa kwenqwaba ye-Bite, amakholomu ensimbi engaphansi komhlaba, nokususwa kwenqwaba.
