1. Ukukhiqizwa kwezinqwaba zamapayipi ensimbi kanye ne-casing yensimbi
Amapayipi ensimbi asetshenziselwa izinqwaba zamapayipi ensimbi kanye nebhokisi lensimbi elisetshenziselwa ingxenye engaphansi kwamanzi yemigodi kokubili kugingqelwa esizeni. Ngokuvamile, amapuleti ensimbi anobukhulu obuyi-10-14mm akhethiwe, agoqwe abe yizigaba ezincane, bese ehlanganiswa zibe izingxenye ezinkulu. Ingxenye ngayinye yepayipi yensimbi ihlanganiswe namasongo angaphakathi nangaphandle, futhi ububanzi be-weld seam abukho ngaphansi kuka-2cm.
2. Umhlangano webhokisi elintantayo
Ibhokisi elintantayo liyisisekelo sika-crane ontantayo, ohlanganisa amabhokisi ensimbi amaningana amancane. Ibhokisi elincane lensimbi linomumo ongunxande elinamakhona ayindilinga ngezansi kanye nesimo esingunxande phezulu. Ipuleti lensimbi lebhokisi liwugqinsi elingu-3mm futhi linengxenye yensimbi ngaphakathi. Ingaphezulu lishiselwe nge-engeli yensimbi ne-steel plate enezimbobo zamabhawodi nezimbobo zokukhiya. Amabhokisi ensimbi amancane axhunywe kwelinye ngokusebenzisa amabhawodi nezikhonkwane zokukhiya, futhi izimbobo zebholidi yehange zigcinwe phezulu ukuze zixhume futhi zilungise imishini yehange noma ezinye izinto ezidinga ukulungiswa.
Sebenzisa i-crane yemoto ukuze uphakamise amabhokisi ensimbi amancane uwafake emanzini ngalinye ngalinye ogwini, futhi uwahlanganise ebhokisini elikhulu elintantayo ngokuwaxhuma ngamabhawodi nezikhonkwane zokukhiya.
3. Umhlangano we-crane ontantayo
I-crane entantayo iyisisetshenziswa esiphakamisayo sokusebenza kwamanzi, esakhiwe ngebhokisi elintantayo kanye ne-CWQ20 yensika ye-dismountable mast crane. Uma usuka kude, umzimba omkhulu ka-crane ontantayo uyi-tripod. Isakhiwo se-crane sakhiwe nge-boom, ikholomu, ukusekela okutshekile, isisekelo setafula elijikelezayo kanye nekhebhu. Isisekelo sesisekelo se-turntable ngokuyisisekelo singunxantathu ovamile, futhi amawintshi amathathu atholakala phakathi nendawo yomsila we-crane entantayo.
4. Misa inkundla engaphansi kwamanzi
(1) Ihange lika-crane elintantayo; Okokuqala, sebenzisa i-crane entantayo ukumisa ihange ebangeni elingama-60-100m ukusuka endaweni yenqwaba yomklamo, futhi usebenzise iflothi njengomaka.
(2) Ukulungiswa komkhumbi oqondisayo: Lapho ubeka umkhumbi oqondisayo, isikebhe esinenjini sisetshenziswa ukusunduza umkhumbi oqondisayo uye endaweni eklanyelwe inqwaba futhi uyihange. Khona-ke, amawintshi amane (okujwayeleke ukuthi awakwaziwa njengemishini okusetshenzwa kulengwa) emkhunjini oqondisayo asetshenziselwa ukubeka umkhumbi oqondisayo ngaphansi komyalo wokulinganisa, futhi umshini we-telescopic anchor usetshenziselwa ukukhulula ngokunembile indawo yenqwaba yenqwaba yepayipi ngalinye lensimbi emkhunjini oqondisayo ngokusho ukuma kwayo, futhi ifreyimu yokumisa ifakwe ngokulandelana.
(3) Ngaphansi kwenqwaba yamapayipi ensimbi: Ngemva kokuthi umkhumbi oqondisayo usumi, isikebhe esinenjini sizohambisa inqwaba yepayipi lensimbi elishiselwe endaweni yomkhumbi ngomkhumbi wokuthutha futhi simise u-crane ontantayo.
Phakamisa inqwaba yepayipi lensimbi, phawula ubude epayipini lensimbi, ulifake kusukela kuhlaka lokuma, bese ulicwilisa kancane ngesisindo salo. Ngemva kokuqinisekisa uphawu lobude epayipini lensimbi nokungena emfuleni, hlola ukuma bese wenza ukulungiswa. Phakamisa isando sokudlidliza sikagesi, usibeke phezulu kwepayipi lensimbi bese uliqinisa epuleti lensimbi. Qala isando sokudlidliza ukuze udlidlize inqwaba yepayipi lensimbi kuze kube yilapho ipayipi lensimbi liphindela emuva, khona-ke lingabhekwa njengelingene edwaleni elinesimo sezulu futhi ukudlidliza kungase kumiswe. Qaphela ukuma ngaso sonke isikhathi phakathi nenqubo yokushayela.
(4) Isiteji sokwakha sesiqediwe: izinqwaba zamapayipi ensimbi ziye zaqhutshwa futhi isiteji sakhiwe ngokuvumelana nomklamo wesikhulumi.
5. Ibhokisi lensimbi yokungcwaba
Thola ngokunembile indawo yenqwaba endaweni yesikhulumi bese ubeka uhlaka lomhlahlandlela. Ingxenye ye-casing engena emfuleni ishiselwe ngokulinganayo nge-clamp plate ohlangothini olungaphandle lwaphezulu. Iphakanyiswe u-crane ontantayo onesigxobo sehlombe. I-casing idlula kuhlaka lomhlahlandlela futhi izika kancane ngesisindo sayo. I-clamp plate iboshiwe kuhlaka lomhlahlandlela. Ingxenye elandelayo ye-casing iphakanyiswa kusetshenziswa indlela efanayo futhi ishiselwe esigabeni sangaphambilini. Ngemva kokuba i-casing isinde ngokwanele, izocwila ngenxa yesisindo sayo. Uma ingasacwi, izoshiselwa futhi ifakwe esikhundleni phezulu, futhi isando sokudlidliza sizosetshenziselwa ukudlidliza nokuzika. Uma i-casing iphindeka kakhulu, izoqhubeka nokucwila imizuzu emi-5 ngaphambi kokuyeka ukucwila.
6. Ukwakhiwa kwezinqwaba ezimboziwe
Ngemva kokuba i-casing ingcwatshiwe, i-rig yokumba iyaphakanyiswa endaweni ukuze kwakhiwe. Xhuma i-casing emgodini wodaka usebenzisa ithangi lodaka bese ulibeka endaweni yesikhulumi. Umgodi wodaka yibhokisi lensimbi elenziwe ngezingcwecwe zensimbi futhi elishiselwe endaweni yesikhulumi.
7. Imbobo ecacile
Ukuqinisekisa ukumnika okuphumelelayo, indlela yokuhambisa igesi ehlehlayo isetshenziselwa ukufaka amanzi ahlanzekile esikhundleni salo lonke udaka emgodini. Okokusebenza okuyinhloko kokujikeleza kokuhlehla komoya kuhlanganisa i-air compressor eyodwa engu-9m ³, ipayipi elilodwa lensimbi elinodaka elingu-20cm, ipayipi lomjovo lomoya elingu-3cm, kanye namaphampu odaka amabili. Vula imbobo ethambekele phezulu engu-40cm ukusuka phansi kwepayipi lensimbi bese uyixhuma epayipini lomoya. Lapho uhlanza imbobo, yehlisa ipayipi lensimbi enodaka liye ku-40cm ukusuka phansi embobeni, bese usebenzisa amaphampu amanzi amabili ngokuqhubekayo ukuthumela amanzi ahlanzekile emgodini. Qala i-compressor yomoya futhi usebenzise isimiso sokujikeleza okuphambene ukuze ufafaze amanzi kusukela ekuvuleni okuphezulu kwepayipi lensimbi ye-slag. Ngesikhathi senqubo yokwakha, kuyadingeka ukuqinisekisa ukuthi ikhanda lamanzi ngaphakathi komgodi liyi-1.5-2.0m ngaphezu kwezinga lamanzi omfula ukuze kuncishiswe ukucindezela kwangaphandle odongeni lwe-casing. Ukuhlanzwa kwe-borehole kufanele kwenziwe ngokucophelela, futhi ubukhulu be-sediment ngaphansi kwe-borehole akufanele budlule u-5cm. Ngaphambi kokufakwa (ngemuva kokufakwa kwe-catheter), hlola ukucwiliswa kwe-sedimentation ngaphakathi komgodi. Uma idlula izidingo zokuklama, yenza ukuhlanza kwesibili komgodi usebenzisa indlela efanayo ukuze uqinisekise ukuthi ukushuba kwe-sedimentation kungaphansi kwenani elishiwo.
8. Ukuthela ukhonkolo
Ukhonkolo osetshenziselwa ukumba izinqwaba uxutshwa ngendlela emaphakathi endaweni yokuxuba bese uthuthwa ngamathangi kakhonkolo ukuyiswa esikhumulweni semikhumbi sesikhashana. Misa i-chute esikhumulweni semikhumbi sesikhashana, bese ukhonkolo ushelela ukusuka ku-chute ungene ku-hopper emkhunjini wokuthutha. Umkhumbi wezokuthutha ube usuhudulela i-hopper endaweni bese uyiphakamisa nge-crane entantayo ukuze ithulule. I-conduit ngokuvamile ingcwatshwa ekujuleni kwamamitha angu-4-5 ukuze kuqinisekiswe ukubumbana kukakhonkolo. Kudingekile ukuqinisekisa ukuthi isikhathi ngasinye sokuthutha asidluli imizuzu engama-40 nokuqinisekisa ukuwohloka kokhonkolo.
9. Ukudilizwa kwenkundla
Ukwakhiwa kwesisekelo senqwaba kuyaqedwa, futhi isiteji siyadilizwa kusukela phezulu kuye phansi. Inqwaba yamapayipi kufanele ikhishwe ngemva kokususwa kwemishayo eguquguqukayo kanye ne-longitudinal kanye nokusekela okutshekile. I-crane entantayo ephakamisa isando sokudlidliza ibopha ngokuqondile udonga lwepayipi, iqala isando sokudlidliza, futhi iphakamise kancane ihhuku ngenkathi idlidliza ukuze ikhiphe inqwaba yepayipi. Abatshuzi bangene emanzini ukuze banqamule izinqwaba zamapayipi axhunywe kukhonkolo nedwala.
