He hononga tata te tawhiti o te wiri i te raima me te wā wiri. Kia tawhiti rawa te wāhi e whakamahia ana, ā, kāore pea e nui te wiri e pā ki ngā wāhi iti o te raima. Waiho kia kotahi te tūranga mō te wā roa rawa, ā, ka tīmata pea te wehewehe o te ranunga e taea ana te whakamahi. Ko te otinga mahi ko te kaua e maumahara ki tētahi tau makutu, nā te mea he āhua kino te kore aro ki ngā tau makutu o te raima. Engari, me whakakotahi e ngā kaiwhakahaere te whānui o te pane wiri, te kaha ki te mahi i te raima, te ātea whakakaha me ngā tohu whakapūmau e kitea ana hei whakatau ko tēhea te wāhi hei whakauru i te wiri me te wā e neke atu ai.
Hei tīmatanga whai hua mō te mara, e taunaki ana a Wacker Neuson kia nekehia ngā pūwāhi rumaki mā te 8–10 ngā wā o te whānui o te pane o te wiri . E tohutohu ana hoki ki ngā kaiwhakahaere kia whakakīkī kia mutu rā anō te pikinga o ngā mirumiru hau, kia mutu hoki te huri o te tangi o te wiri. Mā ēnei kitenga e rua ka hoatu ki ngā tīma o te papa he mea whai hua ake i te tūtohi mokowā pumau: he tātaitanga tīmatanga ka taea te tirotiro ki ngā mahi a te raima.
Mā te mokowā tika o te whakaurunga wiri raima ka taea te taupatupatu i ngā rohe wiri whai hua huri noa i ngā pūwāhi whakaurunga tata. Ki te kore e taupatupatu, ka noho tonu pea ngā rīpene raima kāore i tino pakari i waenganui i a rātou. Ki te tata rawa ngā pūwāhi whakaurunga, ka heke te hua, ā, ka taea te wiri anō i te raima kua pakari i mua, kāore he painga tūturu.
Mā te ture 8–10-ngā-wā-o-te-upoko ka taea te tīmata i tētahi tātaitanga whaihua. Hei tauira, mā te pōka 38 mm ka puta he whānuitanga mokowā tīmatanga tata ki te 304–380 mm (12–15 inihi) . Ehara tēnei i te kī me whakamahi ia wiri 38 mm i taua mokowā tonu. Ka taea e te pupūtanga whakapakari, te ōritetanga o te raima me te mahi wiri te whakarerekē i te radius mahi whai hua, nō reira me whakaū te kaiwhakahaere kei te kitea te pānga o ia whakaurunga ki te rohe tata. E kī ana a Wacker Neuson ka rerekē te mahi whai hua i runga i ngā āhuatanga whakahaere, ā, e taunaki ana ia kia whakamātautauhia i raro i ngā āhuatanga o te papa mahi.
| Āhuatanga o te Pae | Huarahi Tīmata | Ngā mea hei tirotiro |
|---|---|---|
| Pōka 38 mm | Te tawhiti tata ki te 304–380 mm | Whakaūtia ngā rohe whakakotahitanga taupatupatu |
| Whakakaha pūmau | Whakamahia he upoko iti ake, ā, he tawhiti tata atu | Me haere noa te pōka i waenga i ngā pae |
| Wāhanga raima tuwhera nui | Mā te upoko nui ake ka taea te whakawhānui ake i te tawhiti | Tirohia te whānuitanga tuturu o te mahi |
| Raina pakari | Tīmatahia me te āta tirotiro me ngā whakaurunga tata | Kia mataara ki ngā mirumiru e toe ana me ngā wāhi kāore i te tino tau. |
He mea nui te rahi o te pane nā te mea he nui ake te pānga o ngā pane nui ki te raima, engari kāore te nui ake i te pai ake. Ka hoatu e Wacker Neuson te 30 mm hei tauira mō ngā hanganga whaiti me te 58 mm mō ngā wāhanga raima nui ake. I roto i ngā pou, i ngā pakitara rānei kua tino whakapakaritia, he mea nui ake te urunga atu i waenga i ngā pae i te hipoki arorau. Ko te pōka e kore e taea te tae atu ki te raima ehara i te mea whakamiharo, ahakoa te rahi o te āhua i roto i te rārangi pukapuka.
Mō ngā kaimahi kirimana e pātai ana kia pēhea te roa o te wiri i te raima , ko te awhe tīmatanga tino whai hua ko te 5–15 hēkona mō ia whakaurunga . E ai ki te National Precast Concrete Association, e whakamahi ana i ngā aratohu a te Portland Cement Association, ka nui te whakapūmautanga o tēnei wā, ahakoa he rerekē te wā tuturu i runga i te rahi o te wiri, te kaha mahi o te raima me te hohonu o te mema.
Heoi, me whakaū te uati mutu i te whakaaro o te kaiwhakahaere, kaua e whakakapi. Me haere tonu te wiri i te mea e puta mai ana ngā mirumiru hau nui, ā, e kitea ana te noho o te raima i te taha o te pane. E taunaki ana a Wacker Neuson kia mutu te mahi ina kore e ara ake ngā mirumiru, ā, ka mutu te huri o te haruru rumaki. I roto i ngā kupu mahi, ko te tikanga o tēnei ka tere te urupare a te ranunga mākū, ka taea te mahi, engari ko te ranunga pakari me roa ake te wā, me tata atu rānei ngā pūwāhi whakauru.
| Pātai Whakahaere | Tohutoro Whaihua | Tirotiro Pae |
|---|---|---|
| Kia pēhea te roa mō ia whakaurunga? | Tata ki te 5–15 hēkona | Ka mutu te nuinga o ngā mirumiru nui, ā, ka tau te raima |
| Kia pēhea te tawhiti? | Tata ki te 8–10 × te whānui o te pane | Ka taupatupatu ngā rohe wiri tata |
| Kia pēhea te tere o te tango moni? | Tata ki te 3 hēkona mō ia 300 mm | Ka kati te kōhao i muri i te pōka |
| Tohutoro hiki mōrahi | Tata ki te 500 mm | Kei roto tonu i te taea te toro atu o te paparanga katoa |
| Te urunga ki te hiki o mua | Tata ki te 50–100 mm | Ka whakakotahi ngā paparanga hou e rua |
Ahakoa te wā wiri tika o te raima, ka moumou pea mēnā ka tere rawa te kume i te pōka. Ka taea e te tango tere te waiho i tētahi awa i muri i te pane i mua i te wā e rere ai te raima e karapoti ana ki te hoki. Ka hoatu e te NPCA tētahi ture whai hua mō te 3 hēkona mō ia 300 mm (1 putu) o te tango poutū . Ko te tikanga me tuku te wiri kia totohu i raro i tōna ake taumaha, kātahi ka tangohia mārire i te wā e kati ana te raima i muri i a ia.
Koinei anō te take me karo ngā kaiwhakahaere i te whakamahi i te pōka hei taputapu neke raima. Mā te tōia taha i roto i te ranunga ka puta he whakakotahitanga kore taurite, ā, ka uaua ake te pupuri i tētahi tauira whakauru pūnaha. Mā te whakaurunga poutū, te noho poto me te tango whakahaere ka māmā ake te mahi i te mahi mai i tētahi wāhanga o te ringihanga ki tētahi atu.
He māmā ake te whakakotahi i ngā pakitara hōhonu, ngā turanga me ētahi atu whakatakotoranga nunui i roto i ngā ararewa whakahaeretia, kaua e ngana ki te wiri i te hōhonutanga nui rawa i te wā kotahi. E taunaki ana a Wacker Neuson kia puritia ngā paparanga raima takitahi ki te mōrahi o te 500 mm . Ina whakatakotoria te paparanga hou e whai ake nei, me uru te pōka ki roto i te paparanga i raro iho i te 50–100 mm . Mā tēnei ka āwhina i ngā ararewa e rua kia whakakotahi puta noa i ō rāua atanga, kaua e mahi pērā i ngā paparanga motuhake.
He ngāwari te wareware i taua taupatupatu iti i te wā e ringihia ana te kohatu, engari he mahi nui tāna. Mā te whakamutu i te poka i te rohe i waenga i ngā paparanga ka waiho he atanga kāore i te tino pakari. Ka moumou taima noa iho te tākai hohonu ki roto i ngā rauemi kua oti kē te whakapūmau. Ko te whāinga he taupatupatu whakahaere, ehara i te keri keri whenua.
He pai te whānui o te pane mō te whakatau tata i te mokowā o te wiri poker , engari kāore te whānui anake e whakaahua i te pūnaha wiri katoa. Ka pā hoki te auau me te kaha ki te whakawhiti i te wiri ki te raima hou. Hei tauira taputapu, ka whakarārangihia e Multiquip he wiri ā-roto UM13825 38 mm i te 200–258 Hz, he rite ki te 12,000–15,500 wiri ia meneti , me te kaha o te 0.77 mm. He uara motuhake ēnei mō te tauira, kaua ki ngā whāinga whānui, engari e whakaatu ana he aha ngā pane poker e rua he rite te rahi kāore e mahi tahi.
Mō te whiriwhiri taputapu, me titiro ngā kaiwhakatū ki tua atu i te mana o te motuka, i te whānui rānei o te pane anake. Ko te rahi ōrite, te auau mahi, te roa o te pou, te hinganga o te raima me te tahora whakapakari, ka pā katoa ki te ngāwari o te mahi a te kaiwhakahaere ki te whakatutuki i te whakapūmautanga ōrite puta noa i te ringihanga.
Ko te wiri iti e kitea ana i roto i ngā putunga hau e toe ana, i ngā kokonga kāore i tino whakakīia, i te raima rānei kāore anō kia taurite ki te taha o te whakakaha. Ehara i te mea ko te pupuri i te wiri i te wāhi kotahi mō te wā roa te otinga; he pai ake pea te whakauru tata atu me te pūnaha. E whakatūpato ana a Wacker Neuson ko te wiri poto rawa ka waiho te hau kia mau, engari ko te wiri nui rawa ka arahi ki te wehewehe.
Ko te ture māmā rawa atu mō te wāhi mahi ko te whakakotahi i te wā me te tirotiro. Tīmata ki te awhe 5–15 hēkona, mātakitaki i ngā mirumiru, whakarongo ki te wiri, tirohia mēnā kua tau te raima e karapoti ana. Kātahi ka āta hoki atu, ka neke ki te wāhi e taupatupatu ana i muri mai. Mā tēnei huarahi ka taea e ngā kaiwhakahaere te mahi anō me te kore e whakaaro he rite tonu te mahi a ia ranunga raima.
Ko te tīmatanga whai hua he tata ki te 8–10 ngā wā o te whānui o te pane wiri . Mō te pane 38 mm, he rite tēnā ki te 304–380 mm pea. Me whakarerekē te mokowā tuturu mēnā he iti ake te rohe wiri whai hua o te whakakaha, te raima mārō, te whakamātautau papa rānei.
Tata ki te 5–15 hēkona ia whakaurunga he awhe tīmatanga whaihua. Neke atu ina mutu te nuinga o ngā mirumiru nunui, kua tau te raima, ā, kua pumau te tangi o te wiri.
Mō te raima hou e whakatakotoria ana ki roto i ngā ararewa, ko te urunga tata ki te 50–100 mm ki roto i te paparanga o mua he tohutoro whai hua mō te hono i ngā paparanga e rua i te wā e whakaūngia ana.
Kāo. Ka taea e ngā pane nui ake te kapi i te raima, engari me matua puta te āputa whakakaha me ngā rahi o ngā wāhanga. He maha ngā wā ka whai hua ake ngā pane iti mō ngā mahi whaiti me ngā whakakaha kapi, engari ko ngā pane nui ake he pai mō ngā wāhanga tuwhera.
