Ko te rauemi nuinga (one, kirikiri): hanga, me te hoko

rauemi nuinga Non-konganuku he wāhanga faufaa i roto i te ahumahi hanga. Sand, kohatu mongamonga whakamahia i roto i te hanga o te raima, a whakapakaritia hanganga raima, ngā mōtā. E whakamahia ana ēnei rauemi mō te maimoatanga whenua, te whakamahere, mahi whenua. I roto i te ara whakamahia whare paru te rite apa roadbed underlayment. Ētahi momo o te kirikiri e whakamahia mō te whakamahine ngā wāhi tata.

Types o kirikiri me te onepu

Whakaröpütia rauemi hanga wewete katoa rite ki te maha paearu:

• takenga;
• āhuatanga physico-aunoa (kiato, mauroa, ātete matao, hāpainga wai);
• te hanga me te rahi o nga purapura;
• te taumata o te ira, te aroaro o poke waro me inorganic.

Tei Nature takenga kirikiri i runga i te rauemi tīmatanga. Te wehe puehu i toka, rukerukenga ore, e hanga nei i ngā rauemi tukurua me te metallurgical tuarua whiwhi i kuru hanga ururua (raima, pereki). He tika ti'aturi i runga i te rauemi o tona takenga āhuatanga Physico-pūkaha o te paru. Ko te rauemi tino rongonui, e hāngai ana ki toka kaha tiketike - ātete ki te distortion me te whakangaromanga e mahi aunoa. Kei te wehea rahi witi kirikiri ki te maha ngā momo: makeretanga (5 mm), reo (5-25 mm), me te nui (25-40 mm).

E wehea takenga Sand ki tūturu me horihori. hua Natural rauemi noa-rere i roto i te whanaketanga o te onepu onepu ranei me putunga kirikiri. Tei runga i te tupu wehewehe moana, awa onepu maunga ranei. Ko te momo tuatahi e rua he purapura atu porotaka me iti iho ihirangi o poke rite whakaritea ki ngā rauemi i roto i whakapakoko keri. Kei te wehea onepu ki nui, reo, me te iti i roto i pire rahi.

Production o onepu tūturu

Production o tūturu rauemi nuinga kore-konganuku tā maha ngā wāhanga:

• keri;
• tukatuka me te para (ki te hiahiatia);
• rokiroki.

Tata e keri e tuwhera tikanga momo katoa o ngā rauemi nuinga. keri poka onepu e excavators bulldozers ranei. I roto i te hanga o te onepu maunga, e tika ana ki te nui o poke me granules rahi rerekē o, e titau te reira atu tukatuka me te kai haamaitairaa. Kei tēnei tukanga i roto i te horoi me te kōmaka o te rauemi. Hoki te hanga o te hautanga iti whakamahia i roto i te hanga o te whare ranunga e hāngai ana i runga i sima, onepu taea atu huri takai kaiwawahi. E pā ana onepu Natural ki rauemi e pängia ana ki Shade, Heoi i roto i te maha whakamahia tona production tokomaha tonu mō te rauemi nuinga - he pūrere i roto i te puka o te koeko rāpopototia kōaro mō te pupuri me te tuku rauemi korakora.

keri awa onepu te hurihiko ara i roto i Faarii. Waka papa ki papua waipēhi mäminga rauemi raw i te raro o te awa i roto i te toku putunga waipēhi i runga i te pēke. rere hoki ki te awa wai, a ka noho tonu te onepu i roto i te puranga. I mata raro mātotoru rawa whakamahia ato'a peere ararewa.

Production o onepu horihori

Ko te wāhi matawhenua o putunga o onepu taiao kāore, e taea arahi ki te hē o tenei rauemi i roto i te tahi mau rohe. Production o onepu tāwhaiwhai taea te nuinga whakaoti tenei raruraru mā te whakarato i te hiahia e tika ana. rauemi korakora horihori whakaputaina e kuru toka pakeke me ētahi atu puna rauemi raw. Tei runga i te takenga mai o te rauemi ko nga momo e whai ake nei o te onepu horihori:

• Mongamonga. Whakamahia i roto i te titonga waikawa me te whakapaipai. I whakaputahia e kuru mapere, diabase, ōnewa ranei mātotoru slags metallurgical.
• onepu Light, organic me inorganic. whiwhi te rauemi nuinga te i pungapunga, rahoto, tuff, ahuwhenua me te rakau ururua.
• one parataiao - te hua o huri pākeho.
• onepu paru whakawhānui whiwhi i kuru toka keramzite - thermally te tuuraa i rauemi, he filler mo raima ono tekau me te moata.
• onepu maiengi i para.

hanga o te kohatu tukinotia

rauemi Raw mo te hanga o te kohatu mongamonga whakaputaina i roto i te whakapakoko opencast rerekē toka. whiriwhiri Tei runga i te āhuatanga o te moni tāpui me te kamaka keri te ara o te whanaketanga awa. Hoki ngā whakamana toka mārō ngingio tuatahi. Ko te puna i mua i-tāne whakatakotoria te tiaki te. Mongamonga noa i te pahūtanga o te kamaka ki mongamonga e kua riro mo te tukatuka atu.

Ko te rauemi raw tangohia tukua ki te huri kawea nei i roto i o ngā momo o crushers (pukapuka, crushers kauae, pānga, koeko). hanga Tīpakonga o technics te i runga i te momo o te hua whakamutunga rānei. I muri i kuru, rite ki te paru mai ki kōmaka. Kei te wehea te tikanga o te rauemi āta ki hautau rite ki te rahi witi. Tāutatanga Ko te sieves nui maha ki rua o diameters rerekē. Ko te hautau iti haere taumata katoa o ngā mata, noho i roto i te raupo. Ko te tukanga kōmaka i runga i te hautanga kohatu mongamonga kia horoi ki te tango poke paru.

Ko te momo matua o toka kirikiri

He he he rōpū tika nui o enei rauemi, engari i roto ia ratou te nuinga i roto i te tono i te whai ake:

• Ofa'i - te puehu tino roa o te take mai magmatic. Kei te hāngai te reira i runga i - kiripaka, Mika, me te wherepāra. Ko te tae tino noa - whero, māwhero, hina. No te mea o tona takenga mai, te whiriwhiri o tenei rauemi, kia hoatu aro ngā tiwhikete o ira. Nā ki te āhuatanga ōkiko me te pūkaha, te puka e tino paingia ana o paru.
• Kirikiri. Ko te pūtake o tenei toka kamaka rauemi. Te whakaputa i tenei ahua o te puehu i roto i te ara e rua - kuru toka (kirikiri mongamonga), me te āta o te awa whenua moana (kirikiri porotaka) ranei. I runga i te kaha o te ofa'i he nui iho engari iti iti radiation papamuri.
• Quartzite. Ko te rauemi nuinga o ngā kiripaka kamaka. e kore te mea iho ki te ofa'i kaha, engari te mea iti radiation papamuri. Ngā mihi ki te hanganga me te ātaahua colorings taketake tino paingia i roto i whakarakai.
• Pākeho. I whakaputahia e kuru toka parataiao. I runga i te kaha iho ki ētahi atu momo katoa o te otaota. Ko te pūtake o te dolomite me te kotakota. rerekētanga pai - utu iti.

Ngā wāhanga o te tono o ngā rauemi nuinga

Range o tono o kore-konganuku rauemi nuinga e tino nui, uhi tata katoa te wāhanga o te hanganga me te rawaka tono i roto i te tahi atu momo o te mahi:

• Te faaineineraa o te raima o rama rerekē.
• Production o ngā hua raima.
• Road hanga.
• rerewē taputapu, runways.
• Whenua.
• Livestock.
• Taputapu paparanga tiaki i runga i ngā mata ara haupapa.

Transportation o ngā rauemi nuinga

Te kawe rauemi nuinga i te tereina (tawhiti roa), ara, me te waka awa. Hoki waka tereina nga waka gondola tino pai, taraka, meatia cars - kaata tuwhera Special ki rere aunoa i te mata e. Hoki transportation o onepu me te putunga kirikiri rori taraka e tino tika ana. Tukunga o ngā rauemi nuinga e ngaahi vaká awa - te kōwhiringa waka na'ina'i, engari he hāngai anake i roto i te take o te wāhi arawai tata. I roto i te hariata kore te tūtohu i te ara ki te wahi o te tuku ki te ringihia enei rauemi i roto i te tahi atu waka i roto i te tikanga ki te karo te parekura.

Rokiroki me te hoko

I muri i te tangohanga me te, ki te hiahiatia, onepu kirikiri haamaitairaa i roto i te puka i kite reira ka tono ki te whare putunga te kiritaki. Ia momo me te hanganga hautanga o te rauemi nuinga rongoa wehe. kia wāhi rokiroki maeneene, e kore e ratou kohi anake. Ki te tika, kia atu tiaki i te manawa whenua. I roto i te hotoke, kua whakawāteatia nga rauemi o te hukarere me te hukapapa.

Supply o ngā rauemi konganuku-kore i te rokiroki tino maha e ara. Ko te okotahi he hinonga nui ki ngā rārangi peka tūmataiti. Hoki tukuna haumaru, me te watea o ngā rauemi ki te wāhi kiritaki rokiroki whakamutunga rawa ki rori uru watea. Ko te tikanga whakaritea waka mowhiti unilateral. Hoki ngāwari te utanga, me te ki te ārai Shade te Hiro whakamahia mō ngā rauemi nuinga. Hoki rama Artificial whakaratohia te i te po.
