1. Kupanga milu yazitsulo zachitsulo ndi casing zitsulo
Mapaipi achitsulo omwe amagwiritsidwa ntchito popanga milu yazitsulo zachitsulo ndi chotengera chachitsulo chomwe chimagwiritsidwa ntchito pa gawo la pansi pamadzi la mabowo onse amakulungidwa pamalopo. Nthawi zambiri, mbale zachitsulo zokhala ndi makulidwe a 10-14mm zimasankhidwa, kukulungidwa m'zigawo zing'onozing'ono, kenako ndikuwotcherera m'zigawo zazikulu. Chigawo chilichonse cha chitsulo chitoliro chimapangidwa ndi mphete zamkati ndi zakunja, ndipo m'lifupi mwa msoko wa weld si osachepera 2cm.
2. Kusonkhana bokosi loyandama
Bokosi loyandama ndiye maziko a crane yoyandama, yokhala ndi mabokosi angapo achitsulo. Bokosi laling'ono lachitsulo limakhala ndi mawonekedwe amakona omwe ali ndi ngodya zozungulira pansi ndi mawonekedwe amakona apamwamba pamwamba. Chitsulo chachitsulo cha bokosilo ndi 3mm wandiweyani ndipo chimakhala ndi gawo lachitsulo mkati. Pamwamba pake amawotchedwa ndi ngodya yachitsulo ndi mbale yachitsulo yokhala ndi mabowo a bawuti ndi mabowo otsekera. Mabokosi azitsulo ang'onoang'ono amagwirizanitsidwa wina ndi mzake kudzera m'mabotolo ndi zikhomo zotsekera, ndipo mabowo a nangula amasungidwa pamwamba kuti agwirizane ndi kukonza makina a nangula kapena zipangizo zina zomwe ziyenera kukonzedwa.
Gwiritsani ntchito makina opangira galimoto kuti mukweze mabokosi ang'onoang'ono achitsulo m'madzi mmodzimmodzi pamphepete mwa nyanja, ndi kuwasonkhanitsa m'bokosi lalikulu loyandama powalumikiza ndi mabawuti ndi mapini okhoma.
3. Kusonkhana kwa crane yoyandama
Crane yoyandama ndi chipangizo chonyamulira madzi, chomwe chimapangidwa ndi bokosi loyandama ndi crane ya CWQ20 dismountable mast. Kuchokera patali, thupi lalikulu la crane yoyandama ndi katatu. Mapangidwe a crane amapangidwa ndi boom, column, support slant, rotary table base ndi cab. Maziko a turntable base kwenikweni ndi makona atatu wokhazikika, ndipo ma winchi atatu ali pakatikati pa mchira wa crane yoyandama.
4. Konzani nsanja pansi pa madzi
(1) Chingwe choyandama chozikika; Choyamba, gwiritsani ntchito chingwe choyandama kuti muyike nangula pa mtunda wa 60-100m kuchokera pomwe pali mulu wa mapangidwe, ndikugwiritsa ntchito choyandama ngati cholembera.
(2) Kukonzekera kotsogolera chombo: Poika chombo chotsogolera, bwato la injini limagwiritsidwa ntchito kukankhira sitimayo kumalo opangira mulu ndikuyiyika. Kenako, ma winchi anayi (omwe amadziwika kuti makina a nangula) pachombo chowongolera amagwiritsidwa ntchito kuyika chombo chowongolera pansi pa lamulo loyezera, ndipo makina a nangula a telescopic amagwiritsidwa ntchito kumasula bwino mulu wa mulu wa chitoliro chilichonse pachombo chowongolera molingana ndi malo ake, ndipo chimango choyika chimayikidwa motsatira.
(3) Pansi pa mulu wa chitoliro chachitsulo: Sitima yotsogolera itayimitsidwa, bwato lamoto limanyamula mulu wachitsulo chowotcherera kupita kumalo oboola ndi sitima yapamadzi ndikuyimitsa chikwangwani choyandama.
Kwezani mulu wa chitoliro chachitsulo, chongani kutalika kwa chitoliro chachitsulo, chilowetseni kuchokera pa chimango choyikirapo, ndikuchimiza pang'onopang'ono ndi kulemera kwake. Pambuyo potsimikizira chizindikiro cha kutalika pa chitoliro chachitsulo ndikulowa mumtsinje, fufuzani verticality ndikukonza. Kwezani nyundo yogwedera yamagetsi, ikani pamwamba pa chitoliro chachitsulo ndikuyimitsa pazitsulo. Yambani nyundo yogwedezeka kuti mugwedeze mulu wa chitoliro chachitsulo mpaka chitoliro chachitsulo chibwererenso, ndiye kuti chikhoza kuganiziridwa kuti chalowa mu thanthwe losasunthika ndipo kugwedezeka kungathe kuyimitsidwa. Yang'anani kuyimirira nthawi zonse poyendetsa galimoto.
(4) Ntchito yomangayi yatha: milu yazitsulo zazitsulo zayendetsedwa ndipo nsanja yamangidwa molingana ndi mapangidwe a nsanja.
5. Chophimba chachitsulo chokwirira
Dziwani molondola malo a mulu pa nsanja ndikuyika chimango chowongolera. Chigawo cha choyikapo chomwe chimalowa mumtsinje chimawotcherera mofanana ndi mbale yochepetsera kumtunda wakunja. Imakwezedwa ndi chikwangwani choyandama chokhala ndi mtengo wamapewa. Chophimbacho chimadutsa mu chimango chowongolera ndikumira pang'onopang'ono ndi kulemera kwake. Chomangira chotchinga chimangiriridwa pa chimango chowongolera. Gawo lotsatira la casing limakwezedwa pogwiritsa ntchito njira yomweyo ndikuwotcherera ku gawo lapitalo. Chosungiracho chikatalika mokwanira, chimamira chifukwa cha kulemera kwake. Ngati sichimiranso, imawotchedwa ndi kusinthidwa pamwamba pa choyikapo, ndipo nyundo yogwedeza idzagwiritsidwa ntchito kunjenjemera ndi kumira. Chophimbacho chikabwereranso kwambiri, chimapitilira kumira kwa mphindi zisanu musanayime.
6. Kumanga milu yoboola
Pambuyo pokwiriridwa, chobowoleracho chimakwezedwa m'malo mwake kuti chibowole. Lumikizani chosungira ku dzenje lamatope pogwiritsa ntchito thanki yamatope ndikuyiyika pa nsanja. Dyenje lamatopelo ndi bokosi lachitsulo lopangidwa ndi zitsulo ndipo amawotchera papulatifomu.
7. Chotsani dzenje
Pofuna kuonetsetsa kuti kulowetsedwa bwino, njira yoyendetsera gasi yozungulira imagwiritsidwa ntchito kusintha matope onse mu dzenje ndi madzi oyera. Zida zazikulu zoyendetsera mpweya zimaphatikizansopo kompresa imodzi ya 9m ³, chitoliro chimodzi chachitsulo cha 20cm, paipi imodzi yojambulira mpweya ya 3cm, ndi mapampu awiri amatope. Tsegulani chitseko cholowera mmwamba 40cm kuchokera pansi pa chitoliro chachitsulo ndikuchilumikiza ndi payipi ya mpweya. Mukatsuka dzenjelo, tsitsani chitoliro chachitsulo cha slurry mpaka 40cm kuchokera pansi pa dzenje, ndipo gwiritsani ntchito mapampu awiri amadzi kuti mutumize madzi oyera mosalekeza mu dzenje. Yambitsani kompresa ya mpweya ndikugwiritsa ntchito mfundo yozungulira kuzungulira kuti mupopera madzi kuchokera kumtunda kwa chitoliro chachitsulo cha slag. Panthawi yomanga, m'pofunika kuonetsetsa kuti mutu wa madzi mkati mwa dzenje ndi 1.5-2.0m pamwamba pa mtsinje wa madzi kuti muchepetse kuthamanga kwa kunja kwa khoma la casing. Kuyeretsa pobowo kuyenera kuchitidwa mosamala, ndipo makulidwe a matope pansi pa dzenje asapitirire 5cm. Pamaso kulowetsedwa (pambuyo unsembe wa catheter), fufuzani sedimentation mkati dzenje. Ngati icho chikuposa zofunikira za mapangidwe, yeretsani dzenje kachiwiri pogwiritsa ntchito njira yomweyi kuti muwonetsetse kuti makulidwe a sedimentation ndi ocheperapo mtengo womwe watchulidwa.
8. Kuthira konkire
Konkire yomwe imagwiritsidwa ntchito pobowola milu imasakanizidwa mokhazikika pamalo osakanikirana ndikunyamulidwa ndi matanki a konkire kupita kumalo osakhalitsa. Khazikitsani chute pa doko losakhalitsa, ndipo konkriti imatsika kuchokera ku chute kupita ku hopper pa sitima yapamadzi. Sitima yapamadzi imakokera chipolopolocho ku bowo ndikuchikweza ndi crane yoyandama kuti ikathire. Njirayi nthawi zambiri imakwiriridwa pakuya kwa 4-5 metres kuonetsetsa kuti konkire imalumikizana. Ndikofunikira kuwonetsetsa kuti nthawi iliyonse yoyendera sipitilira mphindi 40 ndikuwonetsetsa kugwa kwa konkire.
9. Kugwetsa nsanja
Ntchito yomanga maziko a miluyo yatha, ndipo nsanjayo imaphwasuka kuchokera pamwamba mpaka pansi. Mulu wa chitolirocho udzatulutsidwa pambuyo pa kuchotsedwa kwa mizati yopingasa ndi yotalikirapo ndi chithandizo chokhazikika. Nyundo yoyandama yokweza chitoliro imamangitsa khoma la chitoliro, kuyambitsa nyundo yonjenjemera, ndikukweza mbedzayo pang'onopang'ono kwinaku ikunjenjemera kuchotsa mulu wa chitoliro. Osambira adalowa m'madzi kukadula milu ya mapaipi olumikizidwa ndi konkriti ndi mwala.
