1. Pfupiso yepurojekiti
Purojekiti iyi inoshandisa kuvakwa kwakavhurika. Kana kudzika kwegomba renheyo kwakakura kupfuura mamita matatu uye pasi pemamita mashanu, chimiro chekutsigira chinotsigirwa nemadziro ekuchengetedza simba repasi pevhu resimende re φ0.7m*0.5m. Kana kudzika kwegomba renheyo kwakakura kupfuura mamita mashanu uye pasi pemamita gumi nerimwe, φ1.0m*1.2m bored pile + single row φ0.7m*0.5m cement soil mixing pile inoshandiswa. Kudzika kwegomba renheyo kwakakura kupfuura mamita gumi nerimwe, uchishandisa φ1.2m*1.4m bored pile + single row φ0.7m*0.5m cement soil mixing pile.
2. Kukosha kwekudzora kumira kwemusoro
Kudzora kutenderera kwemapombi kwakakosha zvikuru pakuvaka gomba renheyo. Kana kutenderera kwemapombi akaboorwa akakomberedza gomba renheyo kwakakura, kuchaita kuti chimiro chinochengetedza chisave chakaenzana chakakomberedza gomba renheyo, uye kuunza njodzi huru dzakavanzika kuchengetedzeka kwegomba renheyo. Panguva imwe chete, kana kutenderera kwemapombi akaboorwa kwakakura, kuchava nesimba guru pakuvakwa nekushandiswa kwechivakwa chikuru munguva inotevera. Nekuda kwekutenderera kukuru kwemapombi akaboorwa akakomberedza chivakwa chikuru, simba rakatenderedza chivakwa chikuru harizove rakaenzana, izvo zvichatungamira kumaburi muchivakwa chikuru, uye kuunza njodzi dzakavanzika pakushandiswa kunotevera kwechivakwa chikuru.
3. Chikonzero chekutsauka kwekutenderera
Kutsauka kwakamira kwemurwi webvunzo kwakakura. Kuburikidza nekuongorora purojekiti chaiyo, zvikonzero zvinotevera zvinopfupikiswa kubva pakusarudzwa kwemuchina kusvika pakuumbwa kwegomba rekupedzisira:
3.1. Kusarudzwa kwema drill bits, kuomarara kwe geological kwemuchina wekuchera pile rotary mukuita kwekuchera hakuna kufanana, kusarudzwa kwema drill bits hakugone kusangana nezvinodiwa nemamiriro akasiyana e geological, zvichikonzera kutsauka kwema bit, uye kutsauka kwakatwasuka kwe pile hakusviki pane zvinodiwa zvakanyorwa.
3.2. Sirinda yekudzivirira yakavigwa panzvimbo yayo.
3.3. Kubviswa kwepombi yekuboorera kunoitika panguva yekuboorera.
3.4. Nzvimbo yekeji yesimbi haina kumira zvakanaka, nekuda kwekusagadziriswa zvakanaka kwepedhi yekudzora keji yesimbi, kutsauka kunokonzerwa nekukundikana kutarisa pakati mushure mekunge keji yesimbi yaiswa, kutsauka kunokonzerwa nekuyerera kwekongiri nekukurumidza kana kutsauka kunokonzerwa nepombi yakaturikwa keji yesimbi.
4. Matanho ekudzora kutsauka kwekumusoro
4.1. Kusarudzwa kwechidimbu chekuboorera
Sarudza zvidhinha zvebooreso zvichienderana nemamiriro ekuumbwa:
1 ivhu: Sarudza pasi pebhaketi rinotenderera rekuchera, kana dhayamita iri diki, unogona kushandisa mabhaketi maviri kana nebhaketi rekuchera rekuburitsa ndiro.
②Ivhu rakasviba, harina kusimba, ivhu rejecha, dombo rakabatana zvisina kunaka rine zvidimbu zvidiki: sarudza bhaketi rekuboorera rine pasi peviri.
1. Ivhu rakaoma: sarudzai nzira imwe chete yekupinda (pasi rimwe chete nepaviri) bhaketi rekudhirowa rinotenderera, kana bhaketi remazino rakatwasuka.
1. Matombo akachekwa nesimbi uye matombo akapwanyika zvakasimba: anofanira kunge aine chinhu chinoboorera chine denderedzwa resimbi uye bhaketi rekuboorera rine pasi peviri (rine dhayamita imwe chete yehukuru hwezvimedu zvakakura, rine dhayamita mbiri)
⑤dombo repasi pevhu: rakashongedzwa nechinhu chinoboorera checylindrical core - dhiri rekona rakatenderera - bhaketi rekuboorera rinotenderera rine pasi pevhu, kana bhaketi rekuboorera rakatenderera rakatwasuka - bhaketi rekuboorera rinotenderera rine pasi pevhu.
⑥dombo rine mhepo inofefetera: rakashongedzwa nekoni yekoni yekoni yekoni - kona yekoni yekoni yekoni - kona yekubikira inotenderera ine pasi peviri kana dhayamita yacho yakakura zvakanyanya kuti ikwanise kukwira padanho rekuboorera.
4.2. Kesi yakavigwa
Kuti sirinda yekudzivirira irambe yakamira pakuviga sirinda yekudzivirira, kudzora kuyambuka kunofanirwa kuitwa nedaro rakasiyana kubva pamurwi unotungamira kusvika pakati pemurwi kusvika pamusoro pesirinda yekudzivirira yasvika pakakwirira yakatarwa. Mushure mekunge kaburi yavigwa, nzvimbo yepakati pemurwi inodzoserwa nedaro iri uye gwara rakatarwa kare, uye zvinoonekwa kana pakati pekaburi ichienderana nepakati pemurwi, uye inodzorwa mukati me ±5cm. Panguva imwe chete, nzvimbo yakakomberedza kaburi inonamirwa kuti ive nechokwadi chekuti yakagadzikana uye haizodzivisiki kana kuputsika panguva yekuboora.
4.3. Maitiro ekuboorera
Murwi wakaboorwa unofanira kuboorwa zvishoma nezvishoma mushure mekuvhura gomba, kuitira kuti pave nekudzivirira kwakanaka uye kwakasimba pamadziro uye kuve nechokwadi chekuti gomba riri panzvimbo yakakodzera. Munguva yekuboorwa, nzvimbo yepombi yekuboorera inoongororwa nguva nenguva nekusangana kwedaro, uye kutsauka kunogadziriswa pakarepo kusvika nzvimbo yegomba yagadziriswa.
4.4. Nzvimbo yekeji yesimbi
Kuonekwa kwekutsauka kwemurwi wesimbi kunobva pakutsauka pakati penzvimbo yesimbi nechepakati penzvimbo yakagadzirwa, saka nzvimbo yenzvimbo yesimbi chinhu chakakosha mukudzora kutsauka kwenzvimbo yesimbi.
(1) Matanda maviri ekurembera anoshandiswa kana keji yesimbi yaiswa pasi kuti ive nechokwadi chekuti keji yesimbi yakamira zvakanaka mushure mekusimudzwa.
(2) Zvinoenderana nezvinodiwa nekodhi, padhi rekudzivirira rinofanira kuwedzerwa, kunyanya panzvimbo yepamusoro pemurwi panofanira kuwedzerwa padhi rekudzivirira.
(3) Mushure mekunge keji yesimbi yaiswa mugomba, dhonza mutsetse wepakati kuti uone nzvimbo yepakati, wobva waita daro riri pakati pepakati penzvimbo yekusangana nekudzoreredzwa kwemurwi nekudhirowa murwi negwara rakatarwa. Enzanisa mutsetse wakamira wakarembera nepakati pekeji yesimbi, uye gadzirisa keji yesimbi nekufambisa crane zvishoma kuti uve nechokwadi chekuti nzvimbo mbiri dzacho dzakabatana, wobva wabatanidza mutsetse wekuisa kuti mutsetse wekuisa usvike pamadziro esirinda yekudzivirira.
(4) Kana kongiri yakadururwa yave pedyo nekeji yesimbi, deredza kumhanya kwekudurura kongiri uye chengeta nzvimbo yekatheta pakati pegomba.
