Paipa tāutanga: Methods me Technologies

Ko te whanaketanga o te ahumahi hou, me te ōhanga tāone ko tino taea waho te whakamahi o pipelines mō ngā take rerekē. Kia whakaratohia mahi ore o te wai whakawera, parakaingaki, hau, rārangi hinu, a na i runga i. G. raro anake ki nga tikanga o hangarau me paerewa i roto i ta ratou whakapapanga. tikanga whakaminenga paipa, i reira e maha.

He aha ngā tikanga e taea te whakamahi

Tenei ko nga tikanga matua o te tāuta rārangi:

• tikanga Public tā te whakaminenga o huarahi i runga i nga tautoko, me te kotahi tatau me Faarii haere-i roto i.
• Kati trenchless ranei tikanga. Ko tā te reira i te tuuraa o pipelines i raro i te whenua, kahore whakatuwheratanga whenua.
• aratau Huna. I roto i tenei take, keria te totoro putorino o ngā rua.

No te raina whakaminenga, i runga i nga āhuatanga o te reo kawea rānei, e taea te whakamahi tikanga o tāutanga me te ambient tikanga o te putorino, i hanga o ngā rauemi rerekē: raima, whakarewa, kirihou, uku, papa kiripaka. I roto i te pa e taea te whakamana supply wai putorino whakapanga i roto i te taua waikeri ki ētahi atu kōrero (huarahi whakawera, ngā pūnaha taura me te t.). Kei te whakaaetia te reira ki te whakamahi i rite te hangarau awa me te hongere.

Āhuatanga he tikanga tuwhera o whakapanga pipelines

Na roto i te kia kawea ai he tukanga taua i roto i te whakapanga putorino whakawera, supply wai, rerenga parukore, me te pera i runga i. G. I raro i te whakamahi takere irava raina versus tikanga rua kua kotahi painga motuhake. e kore e putorino whakatakotoria i roto i a ratou i raro ki te pēhanga i roto i te haamaeeraa oneone nekehanga ranei, a reira muri roa. whakaaro te ngoikoretanga o tenei tikanga te ki kia rawakore uru ki rori, ki te tika, hanga ratou.

tāutanga paipa i roto i te takere rere ko atu te utu. Heoi, i roto i tenei take, tohunga te taviniraa kamupene whai wāhi ki te huarahi kahore i te hiahia mō te arearenga.

Runga ake putorino whenua te nuinga whariki anake i roto i ngā wāhi kino o whakataunga tangata, kia rite ki rori poto, me te pera i runga i. Tautoko D. raro kia ratou katoa o raima me te whakarewa hanganga, overpasses, whare me taiepa pera. D.

kia rerekē ngā tikanga pipelines i roto i ngā wāhi tāone. Otiia i roto i tetahi take unuhia te aho o whakataunga i roto o te rohe pēhanga i roto i te oneone i ngā tipu me ngā whare. E āwhina ana tēnei ki te tiaki i nga turanga o te pakaruhanga i roto i te take. tāone raro katoa taputapu e wehea ki ngā rōpū matua e toru: matua, tauwhiro, me te tohatoha. Ko te momo tuatahi e nui kōrero whatunga katoa o te kainga. pipelines tauwhiro i roto i te rohe o te pa, engari kahore e kore e whakamahi i te reira. raina tohatoha Piiraa whakawhānui i te matua tika ki te whare.

tikanga huna o whakapanga

whakamana paipa hanga e tenei tikanga te atu pinepine. Ko te painga matua o whakapanga putorino i roto i te waikeri ko tona cheapness whanaunga. Heoi, i roto i tenei take kia kitea te tukanga whakaminenga tino. I muri i te katoa, te uru ki nga putorino i roto i tenei take, ko te uaua, me te me whakarite e te hanga o te paipa e hiahiatia rite pinepine rite taea.

Ture o te mahi ki te gasket huna

Ka taea te whakamahi ngā rua i raro i te huarahi melkozaglublennye hohonu ranei. I roto i te take tuatahi, ko te paipa whakapapanga hanga e 50-90 cm. A, no te te whakamahi i te tikanga o te waikeri hohonu keri i raro i te mīti whenua. Whakapanga taea te kawea i roto i runga i te hohonu ahumahi o 5 m ina whakapanga rārangi putorino Ngā taua whakaaro .:

1. Ki te te raru oneone, e whakatakotoria putorino tika i runga i taua mea.
2. A, no te whakapanga i te hohonu o neke atu i te 4 m, ranei, ki te e hanga o rauemi kaha rawa nga ngongo, whakarite tïpako horihori. Na te mahi i te rārangi whakaratohia i roto i te tikanga hydrogeological huihui matatini.
3. rite te raro o te waikeri kei roto i te ara taua e haere mai i te putorino ki whakapā ki a ia puta noa. ki tonu ngā kau rohe i te onepu oneone ranei.
4. I roto i te aroaro o te wai whenua i roto i nga wahi i raro poka whakarite mo ratou hōneatanga.

momo Tāuta huna: āhuatanga hangarau

rārangi whakaminenga Hangarau tae atu tīpakohia i runga i te aha rauemi whakamahia te putorino te rānei. Polymeric e rave rahi mongamonga paiherea (ki runga, ki te 18-24 m roto i te roa) tika i te wāhi rokiroki, a ka tukua ki te wahi o gaskets. Here, i roto i te wā raumati e kohia e ratou ki te aho tonu, a ka whakanohoia i roto i te waikeri. whakamana tāutanga e mīhini fehokotaki'anga pūkoro. I roto i te hotoke whakatakotoria te putorino i roto i te waikeri me tetahi hono e te pia i te tikanga o mowhiti rapa ranei.

Paipa hanga uku hua te pikitanga i runga ki raro. I mua ki te tāutanga o te putorino kua tirotirohia hoki te aroaro o maramara. Hono e ratou whenu uku muranga sealingly me whakaaro raka o te slurry sima. Mō putorino rite pai, me te raima. Ka rite ki te hiri i roto i tenei take e taea te te whakamahi i te mowhiti rapa.

pipelines papa kiripaka sima ki te pēhanga ki runga ki te 0.6 MPa kohia mā te whakamahi i dvuhburtnyh papa kiripaka mamau, a ki te pēhanga ki 0.9 MPa - te whakamahi i te rino flanged. E whakamahi putorino Non-pēhanga karekau porotakaroa. Steel ara te faaineine te whakamahi i fehokotaki'anga.

tikanga trenchless

Paipa Kei te nuinga whakamahia tenei tikanga i te mea e taea hoki te hangarau whakaminenga piringa. Hei tauira, rite i raro i te rārangi kume huarahi pukumahi, rerewē, taputapu waho, me ētahi atu nga tikanga e whai ake nei mo te whakapanga trenchless o pipelines ..:

• poka,;
• aki i roto i;
• kōhao whakapae;
• whakangungu rakau, peia.

jacking

E ai ki tenei hangarau wawahia e pipelines i roto i te onematua me paru oneone. Ki te taea te whakatakotoria ona whakamahi o pipelines ake ki te 60 m Lies tenei tikanga e whai ake nei .:

• He tawhito ngongo maitai i te matamata;
• i te tetahi tawhiti i te tutukitanga keria te poka, me te whakaturia te reira i roto i te Jack waipēhi i runga i te tautoko;
• Kei te tuku iho te reira i ki te rua ki te ngongo whakaurua ki roto i te ngongo diameter iti - «tukipū";
• whakaputaina he poka oneone poua.

Mā te tenei tikanga te whenua i waho e kore e taea te nekehia atu. I roto i te tukanga o te poka hiri e te paenga o te okana.

jacking tikanga, me whakangungu rakau peia hangarau

Kei te hoki ēnei hangarau tino maha whakamahia, ki te tika, te hanga pipelines i raro i te mau fifi. Paipa i pahaki taea ki te hinga ngaahi faingata'a ki runga ki te rau mita. Te ngongo i roto i tenei take e akina atu te mutunga tuwhera ki te whenua. Ko te hua i roto i nekehia atu ai te he plug whenua.

Poka whakangungu rakau ngā o te tautoko, te mata, me te wāhanga hiawero. whakarato ana te rua o te tapahi toka me ngā hanganga hikinga i roto i te ngohi. Ko te wahi tautoko e te puka o te whakakai me tikanga ki te hoatu i te hanganga te rigidity tika. Kei te wahi hiku te mamao whakahaere whakangungu rakau.

kōhao whakapae aronga

whakaaro tenei tikanga te te utu tino. Otira kua ia tetahi painga mārama. Ka taea e te tango te reira i ara te tino mātotoru oneone ki te whakamahi o taua hangarau. Wiri whenua i roto i tenei take e hanga ai o rakau motuhake hono e inihi. Ka taea te kawea arearenga i i te tere 1,5-19 m / h. Kia aroha mai, e kore e taea te whakamahi i tenei hangarau i roto i te aroaro o te manawa whenua rohe.

Ko te kupu, ko te pai rawa o ngā tikanga tei whakapanga pipelines i runga i nga āhuatanga o te oneone, te rauemi o te hanga o putorino, e hiahiatia ana te hanga. I roto i tetahi take, me te aru nga kahiwi hangarau whakaminenga rite. raina High-kounga - kī te mahi maeneene o te tipu ahumahi me taputapu terenga.
