Ko ēhea momo taputapu hanga mō ngā rori ka tino tere ake te kaupapa, ka whakaiti hoki i ngā utu?
Kua Whakaaro Anō Koe He Aha Te Āhua Pōturi O Ngā Kaupapa Rori Ahakoa Te Nui O Ngā Mea Rino I Te Papa Mahi?
Ki te taraiwa koe i mua i tētahi mahi huarahi, ā, ka kite koe i ngā mīhini kōwhai e takoto kau ana, tera pea ka pātai koe ki a koe anō, "Me aua momo taputapu hanga katoa mō ngā rori, he aha te kore ai e tere haere tetahi mea?" Ehara te whakautu i te hōiho; engari ko te mōhio ki te taputapu hei whakamahi, te wā, me te pēhea. Kei raro nei ka wehewehea e mātou ia momo taputapu hanga rori matua, tana mahi tūturu, me ngā huarahi huna e penapena ai—e tahuna ai rānei—te moni.
Te Tokotoru Whakaneke Whenua: Ngā Pūreretā, Ngā Kaitā, me te Mīhini Whakamātautau Kāore i te Tino Pai
Ka tīmata ngā mahi a ngā pūrutō mā te haehae me te pana i te oneone o runga. I te nuinga o ngā mahi o Amerika Te Raki, ka nekehia e rātou te 90–120 m³ ia hāora, engari ka heke taua tau mena ka wareware te kaiwhakahaere ki te whakatītaha i te mata mō te uku piri. Muri iho, ka utaina e ngā waru ngā rauemi ki a ia anō, ka tōia ngā rauemi i raro i te rua kiromita—ko ngā mea katoa e tawhiti atu ana ka tahaetia e ngā taraka para. Ko te mea pouri i konei ko te mīhini whakawātea motuka. E whakamanamana ana ngā pepa motuhake ki te 200 hp, engari ko tōna uara tūturu ko te tika o te arataki laser e pupuri ana i te whenua o raro i roto i te manawanui 10 mm. Ki te kore e kitea taua whakaritenga, ka ringihia e koe he 50 mm o te uku hei "whakamaeneene." Tata ki te $13 mano te nui o ngā rauemi koretake mō ia kiromita o te ara, āe!
Ngā Taputapu Whakakīkī: Sheepsfoot, Pneumatic, Smooth Drum rānei—Ko Wai ka Toa?
I muri i te wehenga atu o ngā kai-neke oneone, mā te whakakīkī e whakatau mēnā ka roa tō rori mō ngā tau tekau, mō ngā tau rua tekau rānei. Ka pokepokea e ngā roera waewae hipi te uku momona-makuku, ka pēhia ngā āputa hau ki raro iho i te 12%. Kāore ngā turanga kirikiri e pai ki aua waewae; me whakamahi rātou i te huinga pokepoke-me-pānga o ngā roera hau (rapa-takahi). I taua wā, ka whakaotihia e ngā whakakīkī wiri pahū maeneene te 150 mm o runga o te turanga kirikiri me te auau tata ki te 28–32 Hz—he teitei hei haruru i ngā matapihi tata, he iti hei karo i te pakaru o te kohatu. Whakawhitihia tētahi o ēnei roera, ā, ka iti rawa te matotoru, ka nui rawa rānei te matotoru, ka puta he pakaru wawe.
Te Mira, te Whakatakoto Papa, me te Oranga Ngaro o ngā Papa
I mua i te putanga mai o te uku hou, ka ngaua e ngā mīhini keri matao te mata tawhito tae atu ki te 100 mita ia meneti. Ka kiia e ngā kaiwhakahaere ko te "mira", ā, ko te mokowā o te pahu e whakatau ana mēnā ka waiho e koe he kakano pai, he paru rānei o te papa horoi. Kātahi ka pā te kirikiri o te kaihanga kirikiri ki te whāriki hou ki te matotoru e hiahiatia ana. Ka whakamahia e ngā mīhini keri kirikiri o ngā huarahi hou ngā pūoko oro hei pupuri i te rerekētanga matotoru i raro i te 3 mm—he iti noa iho, engari ko ia mirimita he rite ki te 12 kg o te ranunga mō ia mita tapawha. Mō tētahi mahi tekau kiromita te roa, e rua ngā ara, ka whakareatia taua hapa 3 mm ki te 240 tana o te uku, tata ki te $18 mano o ngā rauemi. Nō reira, he mea nui te kirikiri.
Ngā Kaiwhakaari Tautoko e Whakaora ana i te Rā: Ngā Utaina Wira, Ngā Whakakīkī, me Ngā Pou Rama
Ka kohia e ngā mīhini uta wira ngā konganuku, ā, ka whāngai i te tipu uku; ka taea e te peere 3-m³ te huri i te 140 ngā wā ia hāora ina papatahi te papa. Tāpirihia he roera whakakīkī ki te taha o te kohi, ā, ka whakaitihia e koe te paheke o te potae uta mā te 8%, ka penapenahia te 12 rita o te hinu tīhi mō ia huringa. Kaua e wareware ki aua pourewa rama kanapa mō te mahi pō; ka inumia e ngā tauira LED te 0.6 rita ia hāora, kaua ki te 2.2 rita mō ngā pūangi whakarewa-haurua tawhito. Mō te kaupapa kotahi marama te roa, ka penapenahia e te pana anake te 1,150 rita o te wahie—ehara i te mea tino nui, engari he nui hei utu mō tētahi pona hou, tika?
Me pēhea te whiriwhiri i te waka tika me te kore e pakaru te tahua
Tīmata ki tētahi pūrongo oneone-pānga: ko te uku kirihou teitei he rite ki te waewae hipi me te 50 tana taraka para. Ko te oneone onepu? Whakawhitihia ki ngā taraka whakakī pahu maeneene me ngā taraka 30 tana. Muri iho, maherehia ngā tawhiti kawe; ko ngā waru te tikanga i raro i te 2 km, ko ngā taraka ka toa i tua atu i tēnā. Hei whakamutunga, tirohia ngā taumata tukunga ā-rohe. Ko te dozer whakamutunga Tier-4 e tahu ana i te 7% iti iho te wahie i te Tier-3, e whakaiti ana i te 2 tana o te CO₂ i roto i te 1,000 hāora mīhini. He pai ki ngā kiritaki taua tatauranga ina whaia e rātou ngā whiwhinga LEED.
Ngā Kōrero Pūrākau e Whakaiti ana i tō Pēke Moni
Pūrākau #1: "Ko te nui ake o ngā papa rakau he rite tonu ki te nui ake o te taumaha." Te Pono: ka taea e te papa rakau akomanga 10-mita te whakatakoto i te 600 tana ia hāora, engari ki te 200 tana anake te hua o tō tipu, ka noho noa te mea nui—ā, ka tahuna e 25 rita o te tīhiera ia hāora noho. Pūrākau #2: "Ka taea e koe te karo i te mira mena ka tāpiri noa koe i te 40 mm o te paparanga." Te Pono: ka kitea ngā kapiti whakaata i roto i ngā marama 18, ka akiakihia te mahi anō. Mā te whakapau $1.20 ia mita tapawha ki te mira i mua ka penapena $7.50 i te whakakapinga wawe. Pūrākau #3: "Kāore ngā roera maitai e hiahia ki te wai i runga i te ranunga wera." Ae; ki te kore he uku ka piri, ka kumea, ka waiho ngā rārangi ka huri hei poka i muri mai.
Rārangi Arowhai Tere i mua i tō Waitohu i te Kirimana Reti
- Kotahi mita te whānui o te pūoro? (āe, he pirihimana wetereo, koinā tā mātou he oro tangata)
- He pūoko auger oro kei te papa whakatō?
- Ka taea e te mīhini hurihuri makariri te whakawhiti i ngā pahu 1.2 m me ngā pahu 2 m i raro i te rua hāora?
- Kei te tutuki ngā pourewa rama i te rāhui haruru ā-rohe (<55 dB i te 50 m)?
Tīkina aua pouaka, ā, ka karohia e koe ngā kereme tino noa e pupuhi ana i ngā tahua mā te 15%.
Nō reira, he aha te hua tuturu o te mōhio ki ō taputapu rori?
Ehara i te mea ngāwari ki ngā tohunga mīhini te mārama ki ngā momo taputapu hanga tika mō ngā rori; ko te mea tere rawa atu mā ngā kaipupuri rakau kia oti wawe ai ngā mahi, kia whiwhi moni tāpiri, kia harikoa ai hoki te waka. Kōwhiria te roera tika, tohua te whānui tika o te papa, ā, whakaritea te mira i mua i te whakatakoto papa, ā, ka taea e koe te whakaheke ngāwari i te 7–10% o ngā para o te papa me ngā para rauemi. I roto i tētahi kaupapa $5 miriona, ko te $350–500 mano tēnā e hoki mai ana ki roto i tō pēke moni—he nui hei utu mō tō mahi e whai ake nei i mua i te whakaotinga o te tono a tō hoa whakataetae. Kāore i te tino kino, āe?
