Nahea te aerodynamics taura?

Takitaha o tatou i te whakahuatia o te parau "parakaingaki" i mua i te kanohi e whakatika kaikohikohi me pūnaha whiowhio, e neke wai tupuhi, me te ururua kāinga. Heoi, e kore te mea anake te kōrero e taea te whakatakotoria i raro i te whenua tenei. Tētahi atu whakatinanatanga o te taura whatunga paipa raro protrudes pana i te wai.

whakaahuatanga

Ko te pūnaha whakaahuatia ko te whatunga o waka tauā raro me takere, e kua tāpae i roto i te waea me te taura hiko. he pūnaha taua taea ngā putorino me poka. Tuatahi mahi mō te whakapanga o taura, te mea te muri e hiahiatia ki te arotake i to ratou whakakapinga, tiaki me te whakapiki ake i te kaha.

Ka taea te whakatakotoria e te taura i roto i te ara tuwhera, e kore e nga aho whakamahia, e whakakapi ratou i nga toa o whare, huna me sewers. Ka whakapūmautia Raina i roto i tenei take e te tikanga o huaki motuhake.

Wāhui o aerodynamics taura

aerodynamics Cable tika ki te tiaki i nga waea i te ari kōhauhau me te kawenga o te oneone, me te papa kohatu. Kei te whakamahia te reira mo tetahi hanga, whakakapinga, me te wana o te whatunga waea, me te hiko, ka whakatuwhera i te oneone, me te whakangaro kahore he tika te mata ara.

Ngā momo o te taura parakaingaki

Ko te whakarōpū tino noa o aerodynamics taura ko tetahi e hāngai e te i runga i te tikanga o whakapanga pipelines. Tāutanga kawea putorino i roto i roto i te waikeri mua-keria. Heoi, whakapanga taea e trenchless, i te mea kei runga ake i te whenua i te taura, a kahore he raruraru te mata oneone. kawea taua tāutanga i roto i te hangarau kōhao whakapae.

kia rerekē taua pūnaha i roto i te rahi me te wāhanga ripeka āhua o puna, nga putorino ratou me te rauemi e whakamahia ana i roto i te hanga o ngā huānga. Ka taea e Wells e kirihou, pereki me te raima. Hoki taua pūnaha whakamahi korere:

• papa kiripaka;
• raima;
• kirihou;
• kaka kōata;
• muka te ware.

He kirihou me te papa kiripaka te tino rongonui. I roto i ētahi wā, hoki putorino whakamahia poraka kirihou, e whai wāhanga maha, ka karanga maha-takere.

pūrere taura tau mahani

arapaki Cable pana wai te takere e te hunga i te hohonu e, tei runga i te wahi i roto i te rauemi whakapanga roto putorino. kia ngotonga ngā i 40 ki te 200 cm. A, no te haere mai te reira ki putorino raima, e taea te whakanohoia e ratou hohonu, engari kia kia whakanohoia te kirihou i te hohonu tino i. faahohonu Mōrahi pipelines e te hunga i raro i te ara Wilkes i, engari te iti - i raro i nga rohe tiriti. I raro i huarahi e kei huānga i te hohonu toharite.

Ko te korere i te rītaha ki 4 mm ia mita, tenei taea te rere tūturu o te wai e taea te tomo i te awa. Taura me putorino i waenganui i nga poka kia whakanohoia i roto i te rārangi tika, engari tukua tonu te neke iti, e kore e waiho te reira nui atu i te 10 mm ia mita o te putorino. Katoa kei 25-150 m manholes, uara whakamutunga i runga i te taura whakapanga kaupapa. Roto te awa ki nui, me te basement kore e kawea i roto i ngōwaea i roto i putorino, no te mea kei te unu nga waea konei hoki te tamahanahana.

kia Kei parakaingaki teretetiera korere maha i roto i te awa kotahi, ai kia te waea mānukanuka te raro i roto i te hunga e e kei ofi ange ki te mata whenua. Kei te whakaaro te reira i te diameter 100 mm o tino pai, engari i roto i te mua whakamahia he putorino 15-cm, i te mea uaua atu ki te takoto taura. I roto i te paihere kore e waiho waea me taura hiko.

manholes taputapu

E eke Manholes mō te momo paipa taura i runga i te taua hangarau rite cesspools tikanga. tohu ratou he ipu ki te raro, te tihi o e kati te pao, ki waenganui reira me te kaki pai whakapumautia. Kua whakaritea nga taiepa taha o te rua mō te urunga me te putanga i te putorino ki ngā taura. Te nuinga o enei oko i pūnaha pao rua, te roto o nei he raka haumarutanga, te kī ki reira he wātea anake i te rangatira puna.

Tei runga i te wahi i te whatunga taura, kia puna:

• bushing;
• o te i runga i;
• wehenga.

tāuta te momo tuatahi kei runga i ngā wāhanga tika, ranei i roto i ngā wāhi i reira e kore ko te ine i te rārangi torotika neke atu i te 30 °. Ki te whakaaro o te runga, me te tahuri ki nga poka, kia tū tata whare ranei i roto i ngā wāhanga o te piko whatunga aua ratou. E kei puna wehe i te huarahi ngā retraction takere maha ranei.

He aha atu e hiahia ana koe ki te mohio e pā ana ki te manholes

Construction o aerodynamics taura kia whakarato mo te tāutanga o puna o rerekē te rahi o, kia waiho ratou nui, a to ratou i te whai wāhi ki te mahi ki te taura, ka tāuta i te taputapu. ipu rua i hanga o ngā rauemi rerekē, engari i roto i nga tau tata kua whakamahia piki hua kirihou ki rara. Ko rawa pono hoki ngā tono i reira e kore te mea nui te kawenga tenei. Hei tauira, i roto i aerodynamics taura e taea te whakatau tūmataiti momo tauira Pit CCP-2, tona diameter ko 136 cm, te reira te taea ki te tāuta i te taputapu.

Mahi i runga i te aerodynamics taura: he taura ki te conductors parahi

Whakapanga o aerodynamics taura, ka e kia whakamahia ki te parahi kaiwhakahaere taura, whakarato te hiahia mō te tāutanga i runga i te mutunga hiri o te taura i te tōkena maitai piauau. Hoki ka whakaritea te reira waea tokotoko. kawea Cabling i roto i runga i te ngā hangarau, whakarato ai hoki whakamau i te pahū taura i runga i ngā pūrere i te momo kōwiri kaata ranei.

E kawea ēnei mahi i te taha o te ope o te poka. Kei te whangai Cable ki te wahi o runga o te pahū, me i te kokoru hongere kia kia kirihou ringaringa taura ranei whakaiti. I te farii haamata te puna tuhi i te tokotoko waea ki te taura, i i te kai pai o te mānukanuka ki te pahū taura kei te tonu aroturuki. A, no te whakapanga iho i roto i te pito whanganga, e takina i te pito mo tightness me te pai i runga i tamahanahana. tāutanga Cable i roto i aerodynamics taura i roto i te hotoke kia whakamana i te pāmahana kahore i raro i te 10 ° C, te mea ki te hanga he takotoranga o mata, tae ai te pāmahana ambient -20 ° C.

Āhuatanga putorino rua-taiepa

aerodynamics ngongo taura Double-taiepa i pakeke mowhiti tiketike, e taea ki te tu atu pikaunga mīhini faahiahia, rawa ki te faatura ki te hua kowakawaka ratou. Paipa i ngäwari pai, ki te awhina o ratou e taea te tiki e koe a tawhio noa te mau fifi i roto i te ara o te ara.

Ka taea e ratou te mahi i runga i te whānui o pāmahana ngā, me te aroaro o oko motuhake taea ki te hanga i ara o tetahi whīwhiwhi. kia whai taua putorino ki te taura tau mahani he roa o 35 ki te 150 m, e tukua e ratou i roto i coils, me whai nairona broaching. Ahakoa i pāmahana iti, pupuri ratou te elasticity me te iti rawa piko pūtoro ko 8 diameters.

mutunga

Ki te tika, he pai eke i roto i te rohe tiriti kia whakaaro i roto i te kaha utanga hoahoa i te 10 taranata. Ki te whakaaro ki te halá, ka faarahi tenei tawhā ki te 80 taranata.
