1. Kugadzirwa kwesimbi pombi mirwi uye simbi casing
Mapombi esimbi anoshandiswa pamirwi yepombi dzesimbi uye simbi yekaseji inoshandiswa pachikamu chepasi pemvura chezvibhorani zvese zvakakungurutswa panzvimbo. Kazhinji, mahwendefa esimbi ane hupamhi hwe10-14mm anosarudzwa, akakungurutswa muzvikamu zviduku, uye obva aiswa muzvikamu zvikuru. Chikamu chega chega chepombi chesimbi chinosungirirwa nemhete dzemukati nekunze, uye hupamhi hwemusono we weld hausi pasi pe2cm.
2. Gungano rebhokisi rinoyangarara
Bhokisi rinoyangarara ndiro hwaro hwekireni inoyangarara, ine akati wandei mabhokisi esimbi. Bhokisi duku resimbi rine rectangular chimiro nemakona akatenderedzwa pasi uye rectangular chimiro kumusoro. Iyo ndiro yesimbi yebhokisi ndeye 3mm gobvu uye ine chidimbu chesimbi mukati. Kumusoro kwakasungwa nekona simbi uye ndiro yesimbi ine maburi ebhaudhi nemakomba ekukiya. Mabhokisi madiki esimbi akabatanidzwa kune rimwe nerimwe kuburikidza nemabhaudhi uye mapini ekuvhara, uye maburi eanchor bolt anochengeterwa kumusoro kuti abatanidze uye kugadzirisa anchor michina kana zvimwe midziyo inoda kugadziriswa.
Shandisa crane yemotokari kusimudza mabhokisi madiki esimbi mumvura rimwe nerimwe pamahombekombe, woaunganidza mubhokisi hombe rinoyangarara nekuabatanidza nemabhaudhi nemapini ekukiya.
3. Inoyangarara crane musangano
Iyo crane inoyangarara chishandiso chekusimudza chekushanda kwemvura, iyo inoumbwa nebhokisi rinoyangarara uye CWQ20 inodzika mast crane. Kubva kure, muviri mukuru wecrane inoyangarara itipodhi. Iyo crane chimiro inoumbwa ne boom, column, slant rutsigiro, rotary tafura base uye cab. Hwaro hwechigadziko cheturntable ndeye yenguva dzose katatu, uye mawinji matatu ari pakati pemuswe weiyo crane inoyangarara.
4. Gadzira chikuva chepasi pemvura
(1) Kireni inoyangarara inosungirira; Chekutanga, shandisa crane inoyangarara kumisa anchor pachinhambwe che60-100m kubva panzvimbo yedhizaini murwi, uye shandisa chinoyangarara sechiratidzo.
(2) Kugadzirisa ngarava: Pakuisa chikepe chinotungamira, chikepe chine mota chinoshandiswa kusundira chikepe chinotungamira kune chakagadzirwa murwi chinzvimbo uye nekuchimisa. Zvadaro, mahwindi mana (anowanzozivikanwa semichina yekumisa) pachikepe chinotungamira anoshandiswa kuisa ngarava inotungamira pasi peyero yekuraira, uye telescopic anchor muchina unoshandiswa kunyatso kuburitsa murwi wemurwi wepombi imwe neimwe yesimbi pane inotungamira ngarava maererano. marongero aro, uye furemu yekumisikidza inoiswa mukutevedzana.
(3) Pasi pemurwi wepombi yesimbi: Mushure mekunge ngarava inotungamira yamiswa, chikepe chine mota chinotakura murwi wepombi yesimbi yakasungwa kuenda kunzvimbo yepier nechikepe chekutakura uye kumisa crane inoyangarara.
Simudza murwi wepombi yesimbi, tara kureba papombi yesimbi, woipinza kubva pafuremu yekumisikidza, woinyudza zvishoma nezvishoma nehuremu hwayo. Mushure mekusimbisa chiratidzo chehurefu papombi yesimbi uye kupinda murwizi, tarisa verticality uye kugadzirisa. Simudza sando yekuzunguza yemagetsi, isa pamusoro pepombi yesimbi woisungirira pandiro yesimbi. Tanga nyundo yekuzunguza kuzunguza murwi wepombi yesimbi kusvika pombi yesimbi yadzokororwa, zvino inogona kunzi yapinda mudombo remamiriro ekunze uye kunyura kunyura kunogona kumiswa. Tarisa verticality nguva dzese panguva yekutyaira.
(4) Nzvimbo yekuvaka yakapedzwa: mapaipi epombi esimbi akafambiswa uye chikuva chakavakwa maererano nepuratifomu yakagadzirwa.
5. Kuvigwa simbi casing
Nyatsoona nzvimbo yemurwi pachikuva uye isa dhizaini. Chikamu chebhokisi chinopinda murwizi chakasungirirwa zvakaenzanirana neplate yekusungirira padivi rekunze rekumusoro. Inosimudzwa nekireni inoyangarara ine danda remafudzi. Iyo casing inopfuura nepadhiraivha uye zvishoma nezvishoma inonyura nehuremu hwayo. Iyo yekusungirira ndiro inosungirirwa pane inotungamira furemu. Chikamu chinotevera checasing chinosimudzwa uchishandisa nzira imwechete uye welded kune chikamu chekare. Mushure mekunge casing yakareba zvakakwana, inonyura nekuda kwehuremu hwayo. Kana isingachanyura, ichave yakasungwa uye inotsiviwa pamusoro pekasi, uye sando yekuzunguza ichashandiswa kubvunda nekunyura. Kana iyo casing ikawedzera zvakanyanya, icharamba ichinyura kwemaminetsi mashanu isati yamira kunyura.
6. Kuvakwa kwemirwi yakacherwa
Mushure mekunge casing yavigwa, rig yekuchera inosimudzwa panzvimbo yekuchera kuvaka. Batanidza casing kugomba rematope uchishandisa tangi yevhu woiisa pachikuva. Gomba redhaka ibhokisi resimbi rakagadzirwa nesimbi ndiro uye rinosungirirwa pachikuva.
7. Bvisa gomba
Kuve nechokwadi kupinza kunobudirira, iyo gasi inosimudza reverse kutenderera nzira inoshandiswa kutsiva madhaka ese ari mugomba nemvura yakachena. Mudziyo mukuru wekutenderera kwemhepo unosimudza mhepo unosanganisira imwe 9m ³ air compressor, imwe 20cm slurry simbi pombi, imwe 3cm mhepo jekiseni hose, uye maviri madhaka pombi. Vhura kuvhura kwakarerekera kumusoro 40cm kubva pasi pepombi yesimbi woibatanidza nehose yemhepo. Paunenge uchichenesa gomba, dzikisa pombi yesimbi inorapika kusvika pa40cm kubva pasi pegomba, uye shandisa pombi dzemvura mbiri kuti urambe uchitumira mvura yakachena mugomba. Tanga air compressor uye shandisa musimboti wekutenderera kutenderera kupfapfaidza mvura kubva pakuvhurwa kwepamusoro kwepombi yesimbi ye slag. Munguva yekuvaka, zvinodikanwa kuve nechokwadi kuti musoro wemvura mukati megomba uri 1.5-2.0m pamusoro pemvura yerwizi kuti uderedze kumanikidza kwekunze pamadziro evhavha. Kucheneswa kwechibhorani kunofanira kuitwa nekuchenjerera, uye ukobvu hwesediment pasi pechibhorani hachifanire kudarika 5cm. Pamberi pekupinza (mushure mekuiswa kwecatheter), tarisa sedimentation mukati megomba. Kana ichipfuura zvinodiwa nedhizaini, ita chechipiri chekuchenesa gomba uchishandisa nzira imwechete kuti uone kuti sedimentation ukobvu ishoma pane yakataurwa kukosha.
8. Kudira kongiri
Kongiri inoshandiswa pakuchera mirwi inosanganiswa nenzira yepakati panzvimbo yekusanganiswa uye inotakurwa nematangi ekongiri kuenda kuchiteshi chechinguva. Misa chute pachiteshi chechinguvana, uye kongiri inotsvedza kubva muchute ichipinda muhopi pachikepe chekutakura. Ngarava yekutakura inobva yakwevera hopper kune pier uye inoisimudza neine crane inoyangarara yekudira. Iyo conduit inowanzovigwa pakadzika kwemamita 4-5 kuti ive nechokwadi chekubatana kwekongiri. Izvo zvinodikanwa kuve nechokwadi kuti nguva yega yega yekufambisa haipfuure maminetsi makumi mana uye kuve nechokwadi chekudonha kwekongiri.
9. Platform dismantling
Kuvakwa kwefaundesheni yemurwi kunopedzwa, uye chikuva chinoputswa kubva kumusoro kusvika pasi. Murwi wepombi uchadhonzwa kunze mushure mekubviswa kwematanda akachinjika uye akareba uye tsigiro yakatsetseka. Iyo crane inoyangarara inosimudza vibration sando inosunga zvakananga madziro epombi, inotanga sando yevibration, uye zvishoma nezvishoma inosimudza hoko uku ichibvunda kubvisa murwi wepombi. Vanyuchi vakapinda mumvura kuti vadimbure mirwi yepombi yakabatana nekongiri nedombo.
