Whai hua dewatering: wellpoints, me pehea e mahi ratou me nga hua o te whakamahi i

wai whenua-takoto High tino arai mahi ohaoha, whakakiia waikeri mō ngā heke e haafifi i te tukanga hanga, whakaiti ratou tika, me te mauroa, horoi atu te turanga. Ki te mahi i tenei ranei e pae e tika ana mo te hanga, kawea dewatering tuatahi i roto. Wellpoints whakamahia ki raro i te taumata wai, tukua ki ite i te mahi ara i roto i nga tikanga hydrogeological tino matatini.

Ko te parau tumu taketake o te dewatering

Tīpakonga o te tikanga ngā mō te pā ana ki manawa whenua nui tei runga i taua tawhā rite te rahi me te hohonu rua o te hanganga whare he kaha'ú, geologic nāianei me ngā āhuatanga wai aa, me ētahi atu Heoi, kua whakamahia tetahi dewatering hangarau mō te kotahi whakaaro: .. E tukupu ana o te manawa whenua ki te hohonu taua i runga i e kore ratou e arai i te mahi hanga.

Ko te parau tumu whānui o dewatering tikanga ko ki te waihanga i tētahi kōrere whārua. I te taimau te kutētē te wai i roto i te apa oneone hanga he ahua o te kōrere. I roto i te wahi i reira kawea te dewatering te i roto i, i whai ahua ai wellpoints he pokapū kōhao. Ko te rerekētanga i waenganui i te taumata wai e hiahiatia ana me te wāhi i raro o te depressions kōrere-āhua i huaina korekore kōrere.

Ko te hohonu me te pūtoro o te korekore o te kōrere e whakatakotoria i roto i te ti'aturiraa i runga i nga whakaritenga motuhake me tikanga. E tonu ēnei tautuhinga mo te wā katoa e hiahiatia ana mō te whakahaeretanga o hanga. He mea nui kia ko wellpoint dewatering o te āhua tūturu, me te mea mutu te köurarangi te, ka whakatika i te wai whenua ki te taumata taketake.

wellpoints hoahoa

Enei whakaaro ngā o te ngongo, te mutunga momi o i tāutatia he tātari te. Nā ki te aroaro o te tātari i roto i te tāutanga kore e hinga totoka wellpoint (oneone, onepu, whatiwhatinga toka, a na rerekē. D.).

kua oti te whakarite te diameter me te roa o nga korere i runga i te hohonu o te arearenga heke mai, i te āhuatanga oneone me te hōkaiipurangi e hiahiatia ana rānei.

Te hātepe mahi wellpoints

Tātaitanga o wellpoints whakamana ki te faatura ki te diameter tika o te kōrere. I roto i te tūranga tika tāuta te taputapu e i roto i te whenua i te wahi i reira ka kia tū te taumata wai. Wellpoints mā te awakeri hono ki te papu mo te wai te kutētē. Ka taea e te awakeri te hanga i rapa, whakarewa, i ētahi atu momo o putorino ranei. Ko te mea matua ko te e he pono ratou.

Ko te whānuitanga wellpoint dewatering ka kia whai hua tei runga i te kōwhiringa tika o te kaha papu me te nui tatauranga me te diameter mātau o te putorino momi. Heoi, i ētahi wā e kore koe e taea e hua i te tū oti o te oneone wai-amo, ai runga ake te tetahi kahu aquitard o te wai (0.5-1 m) tonu. Ko tōna tango i te nuinga o rite e whakaritenga o te wa tuwhera, me te dewatering tono o ngā pūnaha köurarangi pūkoro mō te wai te kutētē i roto o ratou.

tikanga dewatering Wellpoint

He ngā tikanga o te whakaiti i te taumata o te manawa whenua mā wellpoints.

• Ki te hiahiatia te mahi hanga te dewatering iti, papua wellpoint he whaiaro-Priming me ngāwari. Ka taea e taua taputapu whakaiti i te taumata o te wai whenua ki te hohonu o 4,5-8,5 m. Ki te tika te mahi tae noa ki te hohonu mōrahi o dewatering whakamahi wellpoints motuhake te hanganga Aratiatia.
• Ki te takoto te tikanga kia heke te taumata manawa whenua ki te hohonu o 18-20 mita, te whakamahi i te ejector motuhake wellpoints papu wai - ejector.
• Hohonu e papua turai o te kaha nui whakamahia mō te dewatering ki te hohonu o runga i te 20 mita.
• E hāngai ana te tikanga korehau te i runga i te whakamahi o ejectors motuhake i roto i nei i te wāhi tātari korehau. E taea e ki tōtika whakaiti te taumata o te wai whenua i roto i ngā āhuatanga hydrogeological o nui haere whīwhiwhi taua pūnaha.

hāngai ana Tīpakonga o te tikanga ngā te i runga i nga āhuatanga dewatering o te whenua, i nga tikanga o to ratou tupu, me te kaha o te aquifer. I tua atu, whakaaro te whakarea tātari e hiahiatia, rohe heke wāhi hangarau hanga o te hanganga maina ranei ngā mahi, te roanga o te dewatering me dewatering āhuatanga o te taputapu.

tāuta wellpoints

Te tohu i te tāutanga o te taputapu dewatering tei runga i te āhuatanga o te oneone i te pae o te mahi hanga i mua nei.

• tono tikanga tāutanga waipēhi ka ki te hiahia whakaiti te taumata o te wai i roto i te takanga me te baked one oneone. Tenei tikanga tā injecting wai ki te pūrere tātari, ka te nei tuku iho ki te whenua.
• e tūtohu tikanga tāutanga Mechanical mō te dewatering wellpoint i roto i te kirikiri me te paru oneone. Hoki puna manga tāne i mua te whakamahi i ngā taputapu motuhake.

Ko te tikanga tino pai o te whakatakoto wellpoints me ratou tokomaha kei te whakaritea e te āhuatanga o te rohe o te waikeri me oneone āhuatanga.

Ko te painga o te whakamahi i wellpoint

• Te wātea o te taputapu dewatering.
• Kawekawe me noho pai o te tāutanga o te pūnaha.
• Kahore he take ki te whakamahi i te hiko (rere wellpoints i runga i diesel).
• Te kaha o te mahi.
• utu iti o te dewatering i roto i rite ki ētahi atu tikanga.
• kakama High.
