1. Kuongorora kweprojekiti
Iyo purojekiti inotora yakavhurika-yakatemwa kuvaka. Kana kudzika kwegomba renheyo kwakakura kupfuura 3 metres uye isingasviki 5 metres, iyo inotsigira chimiro inotsigirwa ne φ0.7m * 0.5m simende ivhu rinosanganisa murwi giravhiti rinochengetedza madziro. Apo kudzika kwegomba renheyo kwakakura kudarika mamita mashanu uye pasi pemamita gumi nerimwe, φ1.0m * 1.2m yakaboora murwi + imwe mutsara φ0.7m * 0.5m simende inosanganisa ivhu rekutsigira murwi rinoshandiswa. Iyo nheyo yegomba kudzika yakakura kupfuura 11 metres, uchishandisa φ1.2m * 1.4m yakaboora murwi + imwe mutsara φ0.7m * 0.5m simende ivhu rinosanganisa murwi rutsigiro.
2. Kukosha kwekutonga kwe verticality
Iyo verticality control yemapile ine kukosha kukuru kune kunotevera kuvakwa kwehwaro gomba. Kana verticality kutsauka akafinhwa mirwi kumativi nheyo gomba yakakura, zvichaita kutungamirira kusaenzana kushushikana yokuchengeta chimiro kumativi nheyo gomba, uye kuunza huru yakavanzwa ngozi kuchengeteka kwehwaro gomba. Panguva imwecheteyo, kana verticality kutsauka kwemurwi wakafinhwa yakakura, ichava nesimba guru pakuvaka uye kushandiswa kwechimiro chikuru munguva inotevera. Nekuda kweiyo yakakura verticality kutsauka kwemurwi wakafinhwa wakatenderedza chimiro chikuru, simba rakatenderedza chimiro chikuru richave risina kuenzana, izvo zvinozoita kuti pave nekutsemuka muchimiro chikuru, uye kuunza njodzi dzakavanzika kune kunotevera kushandiswa kweiyo huru chimiro.
3. Chikonzero chekutsauka kweperpendicularity
Kutsauka kwakamira kwemurwi webvunzo kwakakura. Kuburikidza nekuongororwa kweiyo purojekiti chaiyo, zvikonzero zvinotevera zvinopfupikiswa kubva pakusarudza kwemakanika kusvika kune yekupedzisira gomba kuumbwa:
3.1. Kusarudzwa kwezvimedu zvekuchera, iyo geological kuoma kweiyo inotenderera murwi yekuchera muchina mukuchera haina yunifomu, kusarudzwa kwezviboorero hazvigone kusangana nezvinodiwa zveakasiyana geological mamiriro, zvichikonzera kutsauka zvishoma, uye ipapo kutsauka kwakamira kwe. murwi wacho hauenderane nezvinodiwa zvekutsanangurwa.
3.2. Silinda yekudzivirira yakavigwa kunze kwenzvimbo.
3.3. Drill pipe displacement inoitika panguva yekuchera.
3.4. Kumisikidzwa kwekeji yesimbi hakuna nzvimbo, nekuda kwekugadzika kwakashata kwepadhi yekudzora simbi yesimbi, kutsauka kunokonzerwa nekutadza kutarisa pakati mushure mekunge simbi yesimbi iripo, kutsauka kunokonzerwa nekongiri yakakurumidza. perfusion kana kutsauka kunokonzerwa nepombi yakaturika keji yesimbi.
4. Verticality kutsauka kutonga matanho
4.1. Kusarudzwa kwe drill bit
Sarudza mabhiti eku drill zvinoenderana nemamiriro ekuumbwa:
① ivhu: sarudza chikamu chimwe chete chepasi pechibhorani chekuchera, kana iyo dhayamita idiki inogona kushandisa mabhakiti maviri kana nekuburutsa ndiro yekuchera bhaketi.
②Silt, isina kusimba yakabatana yevhu, ivhu rejecha, isina kunyatso kubatanidzwa hurungudo nehukuru diki: sarudza kaviri-pazasi bhaketi rekuchera.
③ivhu rakaoma: sarudza imwe inlet (imwechete uye yakapetwa kaviri pasi inogona kuva) inotenderera yekuchera bhakiti rekuchera, kana mazino emugomo akatwasuka.
④ matombo akaiswa simende uye matombo akaomeswa zvakanyanya: inoda kuve yakashongedzerwa ine conical spiral drill bit uye kaviri-pazasi rotary bhakiti rekuchera (ine dhayamita imwe chete yehukuru particle size, ine dhayamita yakapetwa kaviri)
⑤stroke Bedrock: yakashongedzerwa necylindrical core drill bit - conical spiral drill - kaviri-pazasi rotary bhaketi, kana yakatwasuka spiral dhiri - kaviri-pazasi rotary bhakiti rekuchera.
⑥Breezed Bedrock: yakashongedzerwa necone core drill bit - conical spiral drill bit - kaviri-pazasi rotary bhakiti rekuchera kana dhayamita rakakurisa kuti ritore danho rekuchera.
4.2. Casing yakavigwa
Kuti uchengetedze verticality yecylinder yekudzivirira pakuviga silinda yekudzivirira, kudzora kwemharadzano kunofanirwa kuitwa nedaro rakasiyana kubva pamurwi unotungamira kuenda kunzvimbo yemurwi kusvika kumusoro kwecylinder yekudzivirira yasvika pakakwirira. Mushure mekunge casing yavigwa, nzvimbo yepakati yemurwi inodzoreredzwa neichi chinhambwe uye negwara rakatemerwa, uye zvinoonekwa kana pakati pekasi inopindirana nepakati pemurwi, uye inodzorwa mukati mehupamhi hwe ± 5cm. . Panguva imwecheteyo, iyo yakapoteredza casing inoputirwa kuti ione kuti yakagadzikana uye haizogadziriswi kana kuparara panguva yekuchera.
4.3. Kuchera maitiro
Murwi wakacherwa unofanirwa kudonhedzwa zvishoma nezvishoma mushure mekuvhura gomba, kuitira kuti ugadzire yakanaka uye yakagadzikana kudzivirira kwemadziro uye kuve nechokwadi chenzvimbo chaiyo yegomba. Panguva yekuchera, nzvimbo yepombi yekuchera inotariswa nguva dzose nemharadzano yedaro, uye kutsauka kunogadziriswa pakarepo kusvikira nzvimbo yegomba yaiswa.
4.4. Kuiswa kwekeji yesimbi
Pile verticality deviation inoonekwa nekutsauka pakati pepakati pekeji yesimbi nepakati pemurwi wakagadzirwa, saka kuiswa kwekeji yesimbi chinhu chakakosha mukutonga kwekutsauka kwenzvimbo.
(1) Mabhawa maviri akarembera anoshandiswa kana keji yesimbi yakaiswa pasi kuti ive nechokwadi cheperpendicularity yekeji yesimbi mushure mekusimudza.
(2) Zvinoenderana nezvinodiwa nekodhi, iyo pedhi yekudzivirira inofanirwa kuwedzerwa, kunyanya munzvimbo yemurwi yepamusoro inofanira kuwedzerwa imwe padhi yekudzivirira.
(3) Mushure mekunge keji yesimbi yaiswa mugomba, dhonza mutsara kuti uone nzvimbo yepakati, uye wobva waita chinhambwe pakati pepakati pemharadzano uye kudzoreredza kwemurwi nekudhirowa murwi uye nzira yakatarwa. Enzanisa mutsara wakarembera wakamira nepakati pekeji yesimbi, uye gadzirisa keji yesimbi nekufambisa zvishoma crane kuti uone kuti nzvimbo mbiri idzi dzinopindirana, wobva washongedza bhara rekumisa kuita kuti bhara rekumisa risvike kumadziro evhavha inodzivirira.
(4) Kana kongiri yakadururwa iri pedyo nekeji yesimbi, deredza kasipidhi yekudira kongiri uye chengetedza nzvimbo ye catheter pakati pegomba.
