1. Ukuveliswa kweemfumba zemibhobho yensimbi kunye ne-casing yensimbi
Imibhobho yentsimbi esetyenziselwa iimfumba zemibhobho yentsimbi kunye nesingxobo sentsimbi esisetyenziselwa indawo engaphantsi kwamanzi yamaqula zombini ziqengqeleke kwisiza. Ngokuqhelekileyo, iipleyiti zetsimbi ezinobunzima be-10-14mm zikhethiweyo, zigqitywe zibe ngamacandelo amancinci, kwaye emva koko zifakwe kumacandelo amakhulu. Icandelo ngalinye lombhobho wensimbi lihlanganiswe ngamakhonkco angaphakathi nangaphandle, kwaye ububanzi be-weld seam ayikho ngaphantsi kwe-2cm.
2. Indibano yebhokisi edadayo
Ibhokisi edadayo isisiseko secrane edadayo, equlathe iibhokisi ezininzi zentsimbi. Ibhokisi yentsimbi encinci inesimo soxande kunye neekona ezijikelezileyo ngezantsi kunye nesimo sexande phezulu. Intsimbi yentsimbi yebhokisi i-3mm ubukhulu kwaye inesahlulo sentsimbi ngaphakathi. Umphezulu udityaniswe ngentsimbi ye-angle kunye nepleyiti yensimbi enemingxuma yebholiti kunye nemingxuma yokutshixa. Iibhokisi ezincinci zetsimbi zixhunywe omnye komnye ngeebholiti kunye nezikhonkwane zokutshixa, kwaye imingxuma ye-anchor bolt igcinwe phezulu ukuze idibanise kwaye ilungise oomatshini be-anchor okanye ezinye izixhobo ezifuna ukulungiswa.
Sebenzisa i-crane yemoto ukuphakamisa iibhokisi ezincinci zentsimbi emanzini enye nganye elunxwemeni, kwaye idibanise kwibhokisi enkulu edadayo ngokudibanisa ngeebholiti kunye nezikhonkwane zokutshixa.
3. Indibano yecrane edadayo
I-crane edadayo sisixhobo sokuphakamisa ukusebenza kwamanzi, esakhiwe ngebhokisi edadayo kunye ne-CWQ20 ye-mast crane ekhutshweyo. Xa usuka mgama, owona mzimba uphambili wecrane edadayo yi-tripod. Isakhiwo se-crane siqulunqwe nge-boom, ikholamu, inkxaso ye-slant, isiseko setafile ejikelezayo kunye nekhebhu. Isiseko sesiseko se-turntable ngokusisiseko ngunxantathu oqhelekileyo, kwaye ii-winches ezintathu zibekwe embindini womsila we-crane edadayo.
4. Misela iqonga elingaphantsi kwamanzi
(1) I-ankile yecrane edadayo; Okokuqala, sebenzisa ikhreyini edadayo ukumisa iiankile kumgama oyi-60-100m ukusuka kwindawo yoyilo lwemfumba, kwaye usebenzise intonga edadayo njengesiphawuli.
(2) Ukulungiswa kwenqanawa ekhokelayo: Xa ubeka isikhephe esikhokelayo, isikhephe esinenjini sisetyenziselwa ukutyhala inqanawa ekhokelayo ukuya kwindawo eyimfumba eyilelwe kwaye iyihange. Emva koko, ii-winches ezine (ezaziwa ngokuba ngoomatshini be-ankile) kwinqanawa ekhokelayo zisetyenziselwa ukubeka inqanawa ekhokelayo phantsi komyalelo womlinganiselo, kwaye umatshini we-ankile we-telescopic usetyenziselwa ukukhulula ngokuchanekileyo indawo yemfumba yemfumba nganye yombhobho wentsimbi kwinqanawa ekhokelayo ngokwendlela yokulinganisa. indawo yayo yokubeka, kunye nesakhelo sokumisa sifakwe ngokulandelelana.
(3) Ngaphantsi kwengqumba yombhobho wentsimbi: Emva kokuba inqanawa ekhokelayo imisiwe, isikhephe esinenjini siya kuthutha ingqumba yentsimbi edityanisiweyo yombhobho ukuya kwindawo yepier ngenqanawa yothutho kunye nedokhi yecrane edadayo.
Phakamisa ingqumba yombhobho wentsimbi, phawula ubude kumbhobho wentsimbi, uwufake ukusuka kwisakhelo sokumisa, uze uwutshone kancinci ngobunzima bawo. Emva kokuqinisekisa uphawu lobude kumbhobho wensimbi kunye nokungena emlanjeni, khangela i-verticality kwaye wenze ukulungiswa. Phakamisa isando sokungcangcazela kombane, sibeke phezulu kumbhobho wentsimbi kwaye uyibambe kwipleyiti yentsimbi. Qalisa isando sokungcangcazela ukuze ungcangcazele imfumba yombhobho wentsimbi de umbhobho wentsimbi ubuyele umva, emva koko unokuthathwa ngokuba ungene kwilitye elinesimo sezulu kunye nokutshona kwevibration kunokumiswa. Jonga ukuma ngamaxesha onke ngexesha lokuqhuba.
(4) Iqonga lokwakha ligqityiwe: iimfumba zemibhobho yensimbi ziye zaqhutyelwa kwaye iqonga lakhiwe ngokuhambelana noyilo lweqonga.
5. Isingxobo sentsimbi yokungcwaba
Ukumisela ngokuchanekileyo indawo yemfumba kwiqonga kwaye ubeke isakhelo sesikhokelo. Icandelo le-casing elingena kwi-riverbed li-symmetrically welded kunye ne-clamp plate kwicala langaphandle eliphezulu. Iphakanyiswe yikhreyini edadayo enomqadi wamagxa. I-casing idlula kwisakhelo sesikhokelo kwaye iyancipha kancinci ngobunzima bayo. I-clamp plate ifakwe kwisikhokelo sesikhokelo. Icandelo elilandelayo le-casing liphakanyisiwe ngokusebenzisa indlela efanayo kwaye i-welded kwicandelo langaphambili. Emva kokuba i-casing inde ngokwaneleyo, iya kutshona ngenxa yobunzima bayo. Ukuba ayisatshoni, iya kudityaniswa kwaye ifakwe endaweni ephezulu kwi-casing, kwaye isando sokungcangcazela siya kusetyenziswa ukungcangcazela kunye nokutshona. Xa i-casing iphinda ibuyele kakhulu, iya kuqhubeka ukutshona imizuzu emi-5 ngaphambi kokuyeka ukutshona.
6. Ukwakhiwa kweemfumba ezombiweyo
Emva kokuba i-casing ingcwatywe, i-drilling rig iphakanyiswe kwindawo yokwakhiwa kokomba. Xhuma i-casing kumgodi wodaka usebenzisa itanki yodaka kwaye uyibeke eqongeni. Umngxuma wodaka yibhokisi yentsimbi eyenziwe ngeepleyiti zentsimbi yaza yadityaniswa eqongeni.
7. Sula umngxuma
Ukuqinisekisa ukunyuswa okuphumelelayo, indlela yokunyusa igesi ejikelezayo isetyenziselwa ukubuyisela lonke udaka olusemngxunyeni ngamanzi acocekileyo. Esona sixhobo singundoqo sokujikeleza umva sokuphakamisa umoya siquka i-9m ³ yomoya omnye, umbhobho omnye wentsimbi eludaka oyi-20cm, umbhobho omnye oyi-3cm, kunye neempompo zodaka ezimbini. Vula ukuvuleka okuthambekele ukuya phezulu kwi-40cm ukusuka ezantsi kumbhobho wentsimbi kwaye udibanise nombhobho womoya. Xa ucoca umngxuma, yehlisa umbhobho wentsimbi enodaka ukuya kwi-40cm ukusuka ezantsi komngxuma, kwaye usebenzise iimpompo zamanzi ezimbini ngokuqhubekayo ukuthumela amanzi acocekileyo emngxunyeni. Qala i-compressor yomoya kwaye usebenzise umgaqo wokujikeleza umva ukutshiza amanzi ukusuka kwindawo ephezulu yokuvulwa kombhobho wensimbi ye-slag. Ngethuba lenkqubo yokwakha, kuyimfuneko ukuqinisekisa ukuba intloko yamanzi ngaphakathi komngxuma i-1.5-2.0m ngaphezu komgangatho wamanzi omlambo ukunciphisa uxinzelelo lwangaphandle kwindonga ye-casing. Ukucocwa kwequla kufuneka kuqhutywe ngononophelo, kwaye ubukhulu bentlenga emazantsi equla akufanele budlule kwi-5cm. Ngaphambi kokufakwa (emva kokufakwa kwe-catheter), khangela i-sedimentation ngaphakathi komngxuma. Ukuba idlula iimfuno zoyilo, yenza ukucoca okwesibini komngxuma usebenzisa indlela efanayo ukuqinisekisa ukuba ubukhulu be-sedimentation bungaphantsi kwexabiso elichaziweyo.
8. Ukugalela ikhonkrithi
Ikhonkrithi esetyenziselwa ukugrumba iimfumba ixutywa ngendlela esembindini kwindawo yokuxuba kwaye ithuthwa ngeetanki zekonkile ukuya kwisikhululo sexeshana. Misa i-chute kwidokhi yethutyana, kunye nezilayidi zekhonkrithi ukusuka kwi-chute ukuya kwi-hopper kwinqanawa yokuthutha. Inqanawa yokuthutha emva koko irhuqa ihopper kwi-pier kwaye iyiphakamise nge-crane edadayo ukuze igalelwe. I-conduit ngokubanzi ingcwatywa kubunzulu be-4-5 yeemitha ukuqinisekisa ukuxinana kwekhonkrithi. Kuyimfuneko ukuqinisekisa ukuba ixesha ngalinye lokuthutha alidluli imizuzu engama-40 kunye nokuqinisekisa ukuchithwa kwekhonkrithi.
9. Ukudilizwa kweqonga
Ukwakhiwa kwesiseko semfumba kugqityiwe, kwaye iqonga liyachithwa ukusuka phezulu ukuya ezantsi. Umbhobho wombhobho uya kutsalwa emva kokususwa kweepali ezinqamlezayo kunye ne-longitudinal kunye nenkxaso ye-slant. I-crane edadayo ephakamisa isando sokungcangcazela iqinisa ngokuthe ngqo udonga lombhobho, iqale ihamile yokungcangcazela, kwaye kancinane iphakamisa ihuku ngelixa ingcangcazela ukususa imfumba yombhobho. Abantywili bangena emanzini ukuze banqumle iimfumba zemibhobho edityaniswe nekonkile namatye.
