He kaiwhakarato taputapu hanga mō ngā mīhini hanga mō ngā tau 30.
Whakaarohia tēnei: kua oti kē te whakakī i tētahi awaawa, he āhua piri te mata, kei te harikoa te kapa, ā, i muri i ngā marama e toru - he poka totohu. Kāore tetahi e hiahia ana ki taua kōrero ki te kiritaki. I te nuinga o te wā, ehara i te mea ko te rauemi whakakī, ko te mahi rānei a te kapa te take. Ko te mīhini hē mō te mahi. Ko te whiriwhiri i waenga i te rammer me te compactor he āhua iti noa iho pea, engari i runga i te papa hanga, ka noho ngā taipitopito iti hei akoranga utu nui. Ka whakamāramahia e tēnei aratohu ngā rerekētanga tūturu kia taea ai e koe te whakatau tika i mua i te ringihanga o te raima - kaua i muri mai.
I te tirohanga tuatahi, te āhua nei he rite tonu te mahi a te rammer me te pereti compactor: ka pēhi i te oneone, ka whakamahia te penehīni, te diesel rānei, ā, ka wiriwiri kia marere ai ō whakakī. Engari he rerekē te āhua o te pēhi i te oneone, ā, koia te rerekētanga katoa.
Ko te mahi a te tāmi tāmi — e kiia ana he pekepeke, koinei pea te īngoa pai rawa atu i roto i ngā taputapu hanga — mā te patupatu i te whenua i ngā wā katoa. Ka whakarewahia te mīhini ki runga e te pūnaha puna, ka panaia ki raro ki runga i te pereti turanga whaiti i waenga i te 500 me te 750 ngā whiu ia meneti. Whakaarohia he peinga pou e kore e mutu te ngenge, e uru ana ki roto i te awaawa. Ko taua pānga kaha, kukū, koinei tonu te mea e pakaru ai ngā matūriki oneone piripono, ka panaia te hau me te wai kua mau.
Engari, he wiri te mīhini whakakī pereti , kaua ki te pēneti. Mā te taumaha hurihuri o roto ka puta he wiri e haere ana i roto i tētahi pereti maitai whānui, papatahi, ki roto i te oneone i raro. Nā aua wiri ka ngaro te piri o ngā matūriki oneone ki a rātou anō mō tētahi wā poto, ka taea ai e rātou te neke me te mau ki tētahi whakaritenga matotoru ake. Ka tere te kapi i te whenua, ka ōrite hoki — he mea pai mō ngā wāhi tuwhera nui, ā, kāore i te tino pai ina mahi ana koe i roto i tētahi awaawa e rua putu te whānui.
Anei te wāhanga e warewarehia ana e te nuinga o ngā aratohu: ehara te momo oneone i te mea kotahi noa i roto i te maha. Koia te mea whakatau. Ki te hē tēnei mahi, ehara i te mea ka whakaiti noa i te whai huatanga — ka kino rawa atu pea te whakakīkī.
Ka honoa ngā matūriki paru me te uku mā te matū o te mata, ehara i te waku. He uaua, he pupuri i te makuku, ā, kāore e pai te aro ki te wiri - koia tonu te take he pakanga hinga te tuku i te mīhini whakakī pereti ki roto i te awaawa kua whakakiia ki te uku. Ko te mea e hiahiatia ana e te oneone piripono ko te pānga tika, te pānga auau hei wawahi i te hononga matūriki me te pana i ngā āputa hau. Koinei te whakaahuatanga mahi a te mīhini whakakī.
He āhuatanga makuku tēnei e kore e arohia. Ka pai te whakakī o te paru i te nui o te makuku - tata ki te 13 ki te 15 ōrau mō te nuinga o ngā oneone uku. I taua awhe makuku, ka taea e te rammer te whakatutuki i te hohonutanga o te whakakī o te 8 ki te 12 inihi i ia hiki. Ki te nui rawa te makuku, ka kirihou te oneone, ā, kāore e mau te matotoru. Ki te nui rawa te maroke, ā, ka ātete rawa ngā matūriki ki te whakakī. Mā te whakamātautau Proctor tere i mua i te tīmatanga o te mahi ka nui ake te wā e penapenahia ana i te utu.
Ka mahi te onepu, te kirikiri, me te konganuku kuru i te waku i waenga i ngā matūriki. Ina pā te wiri ki ēnei rauemi, ka hinga te waku mō te wā poto, ā, ka tukuna ngā matūriki kia whakarite anō kia piri rawa atu - pērā i te rūrū i tētahi ipu kirikiri kia tau rawa. Mā te mīhini whakakī pereti e rere ana i te 75 ki te 100 Hz ka mahi i tēnei puta noa i tētahi wāhi whānui, he auau, he tere hoki.
Ka aha mēnā ka whakamahia he rammer ki runga i te oneone kirikiri? Ka werohia e te waewae whaiti ka nekehia te rauemi ki waho, kaua e pēhi ki raro. Ka puta he kōhao e karapotia ana e te oneone koretake, e āhua rite ana ki te kikī i te mata engari kāore rawa. He hapa tēnei i te mara e uaua ana ki te kite, ā, e ngāwari ana ki te pouri.
| Tauwehenga | Rammer Tāmi | Kaiwhakakī Pereti |
|---|---|---|
| Te āhua o tōna whakakīkī | Pānga patupatu (500–750 BPM) | Te wiri (75–100 Hz) |
| Momo oneone pai rawa atu | Honohono - uku me te paru | Poraka - onepu, kirikiri, kohatu kuru |
| Te hohonutanga o te hiki teitei rawa | 8–12 inihi mō ia haerenga | 6–8 inihi te paerewa; tae atu ki te 12 inihi mō ngā tauira hurihuri |
| Tere kapinga | Pōturi ake — pai rawa atu mō ngā wāhi kuiti | 3–4× te tere ake i ngā mata papatahi tuwhera |
| Taumaha noa | 130–200 pauna | 150–700 pauna i runga i te tauira |
Ko tētahi o ngā hapa e tino kitea ana i ngā mahi whakakīkī ko te ngana ki te whakakīkī i te nui rawa o ngā rauemi i roto i te kotahi haerenga. He mea mārama tēnei - he iti ake te wā e hiahiatia ana mēnā he iti ake te hiki. Engari kāore te ahupūngao e pai. Ka taea e te whakakīkī pereti te akiaki i tōna kaha wiri kia hohonu rawa i mua i te paunga o te mamaoa. Pana atu i taua hohonutanga, ā, ka puta he kirinuku matotoru i runga ake e noho ana i runga i ngā rauemi kua whakakīkīhia i raro. Ka huri taua atanga hei papa rahua i te wā e pāngia ai tētahi kawenga.
Mō tētahi mīhini whakakī pereti paerewa, ko te rohe mahi he 6 ki te 8 inihi o ngā rauemi wetewete mō ia hiki. Ka taea e ngā mīhini whakakī pereti hurihuri me te kaha whakatere teitei ake te pana i tēnā ki te 10 ki te 12 inihi i roto i ngā rauemi kirikiri kua pai te whakarōpū. Nā te mea he poutū ake te haere o tōna kaha pānga me te kaha nui ake mō ia wāhi, ka taea e te mīhini whakakī pereti te whakahaere i ngā hiki tae atu ki te 10 ki te 12 inihi i roto i te whakakī piri - he painga nui tēnei i roto i te whakakī hohonu o te awaawa, ina whakaitihia e ia huringa hiki kua penapenahia te wā mahi tūturu.
Ko tētahi atu mahanga noa ko te aromatawai i te whakakīkī mā te āhua. He iti noa iho ngā kōrero a te mata maeneene, mārō hoki mō te mea e tupu ana i raro i te 6 inihi. Ko te whakahaere i tētahi ine matotoru karihi, i tētahi whakamātautau kōne onepu rānei i te hohonutanga te whakaū pono anake - ā, he pai ki te mahi i tētahi mahi e raru ai te taunga.
Kia tika tā tātou kōrero mō tēnei, nā te mea he nui ake te kino i tā te nuinga o ngā kaiārahi e kī nei. Ko te whakamahi i te mīhini whakakī pereti ki runga i te rua uku-maha tētahi o ngā tino take e kitea ana mō te taunga rerekē i muri i te hanganga. Ka whakakīia e te wiri ngā rauemi kirikiri katoa kei roto i te ranunga engari ka waiho ngā pute piripono e herea noatia ana i raro. E ono marama i muri mai, ka heke te mata o te rori, ka neke te paipa ratonga, ā, ka tae mai te pire whakatika me te riri o te kiritaki.
Ko te raruraru whakamuri — te whakamahi i te patu i runga i te papa raro kirikiri mō te whariki poraka, te ara waka rānei — ka puta he mātotoru kore taurite puta noa i te papa. Ko ētahi wāhi ka piri pai ki te wāhi e pā tika ana te waewae; ko ngā wāhi i waenga i ngā ara kāore. Kia tīmata te utaina o ngā waka, ka whai ake te taunga o ngā pūwāhi me ngā hononga pakaru. Koinei te momo rahunga e ngāwari ana te whakapae i te kounga o ngā rauemi, engari ko te kōwhiringa taputapu te tino take.
Tērā anō hoki te koki kakahu o te mīhini e tika ana kia whakahuatia. Mā te whakamahi i te rammer ki runga i te rauemi kirikiri ka tere ake te kakahu o te pereti waewae me te huihuinga puna, nā te mea ka whawhai te mīhini ki te nekehanga rauemi kaua ki te ātete ki te whakakīkī. Ehara i te mea ka puta he hua kino mēnā ka whakamahia he taputapu hē — ka tere ake te whakapoto i te roa o te ora o ngā taputapu i tā te kamupene reti e mōhio ai.
He māmā ake te anga whakatau i tōna āhua. Mena kei te mahi koe i roto i tētahi awaawa, i te taha o tētahi turanga, i tētahi wāhi iti rānei he whakakī piripono, he whakakī whakauru rānei — ko te rammer tō mīhini. Nā tōna āhua whaiti, tōna kaha pānga nui, me tōna urunga hohonu, koinei anake te kōwhiringa whai hua i roto i ēnei āhuatanga. Mena kei te whakarite koe i tētahi turanga tuwhera mō tētahi rori, papa waka, taupee, huarahi waka rānei mā te whakamahi i te rauemi turanga kirikiri, he tere ake te whakakī pereti, he ōrite ake, ā, he pai ake te pai ki te whanonga o te rauemi i raro i te wiri.
He maha ngā kaimahi kirimana mātau e pupuri ana i ngā mīhini e rua, nā te mea he maha ngā wāhi mahi e whai ana i ngā āhuatanga e rua. Ehara tēnā i te mahi tāpiri – kei te whakaritehia tēnā. Ka taea e te rammer me te pereti compactor te mahi tahi te whakatutuki i ngā āhuatanga compaction katoa ka tūtaki koe i roto i ngā kirimana whānui, ā, he iti ake te utu i te utu o tētahi mahi compaction kotahi kāore i angitu.
Ehara te tautohetohe mō te mīhini rammer me te compactor i te mea ko tēhea mīhini te mea pai ake. Engari ko te mārama he raruraru pūtaiao rauemi te compacting, ā, ko te taputapu tika ko te mea e rite ana ki te ahupūngao o te oneone i tō wāhi. Mā te tika o tēnā, ka whai wāhi te katoa ki te whawhai.
Tohutohu tere mō te mara: me whakataurite tonu ngā raraunga whakakīkī a Proctor o tō pūrongo hangarau whenua me te hohonutanga hiki i tūtohutia e te kaihanga mō te mīhini motuhake e whakamahia ana e koe. Mā ēnei tau e rua e ārai i te nuinga o ngā rahunga whakakīkī i mua i te tīmatanga.
