Ko te kupenga waikeri hiato-toru-ahu he rauemi waikeri e whakamahia whānuitia ana i roto i ngā kaupapa nui. Nā, me pēhea te hono i te wā hanga?
1. Te whakatikatika i te ahunga hononga
I te whakatakotoranga o te kupenga waikeri hiato-toru-ahu, whakatikatikahia te ahunga o te roera rauemi kia tika ai te ahunga roa o te roera rauemi ki te ahunga matua o te rori, o te kaupapa rānei. Mā tēnei whakatikatika ka taea e te kupenga waikeri te pupuri i te mahi waikeri pumau i te wā e pikau ana i ngā kawenga, te whakapai ake i te ara rere o te wai, me te whakapai ake i te pai o te waikeri. Ki te kore e tika te whakatikatika i te ahunga, ka arahi pea ki te waikeri ngoikore, ki te kohikohi wai ā-rohe rānei, ka pā ki te pānga o te kaupapa.
2. Te whakamutu rauemi me te taupatupatu
Me whakamutu te kupenga waikeri whakakotahi-toru-ahu, ā, me taupoki ngā geotextile i runga i ngā pūtake geonet tata i te taha o te hurihanga rauemi. I te wā e taupoki ana, kia tino papatahi te geotextile, kia kore e miro, ā, kia tutuki te roa o te taupoki i ngā whakaritenga hoahoa. I te nuinga o te wā, kaua e iti iho i te 15cm te roa o te taupoki roa, ā, me whakahaere te roa o te taupoki whakararo i roto i te awhe o te 30-90cm. Ki te kore e ranea te roa o te taupoki ka kore e ranea te kaha o te hononga, ka pā ki te pumau o te kupenga waikeri; i te mea ka nui rawa te taupoki ka nui ake te para rauemi me te uaua o te hanga.
3. Te whakamahinga o ngā hononga
I roto i te tukatuka hononga, he mea tino nui te whiriwhiri me te whakamahi i ngā hononga. I te nuinga o te wā, ka whakamahia ngā whitiki kirihou mā, kōwhai rānei, ngā whitiki polymer rānei hei hono i ngā matua geonet o ngā rōra geotextile tata. I te wā e hono ana, whakamahia ngā hononga hei whakau i a rātou i ētahi wā (pēnei i te 30cm, 1m rānei) i te roanga o te rōra rauemi. Me nui te kaha me te pakari o ngā hononga kia mau ai ngā hononga. Ki te kore e whakamahia tika ngā hononga, ka wetekina, ka taka rānei ngā hononga, ka pā ki te pānga rerenga wai o te kupenga rerenga wai.
4. Te whakapiri i ngā geotextiles e taupatupatu ana
Mena ka whakatakotoria te kupenga waikeri whakakotahi-toru-ahu i waenganui i te turanga, te turanga me te turanga raro, me whakau ngā kakano whenua e taupatupatu ana. Ko ngā tikanga whakau ko te whakarewa poro tonu, te whakarewa pane papatahi, te tuitui rānei. I te wā e whakarewa ana, kia ātaahua, kia kore he whakarewa paheke, he pekepeke rānei ngā whakarewa; i te wā e tuitui ana, ka taea te whakamahi i te tuitui pane papatahi, te tuitui whānui rānei hei whakatutuki i ngā whakaritenga roa tuitui iti rawa. Ka taea e te whakau te whakarei ake i te kaha me te pumau o ngā hononga, ā, ka ārai i te nekeneke, te pakaru rānei o ngā kakano whenua i te wā e whakarārangihia ana ngā whakakī.
5. Te maimoatanga taiao motuhake
I ngā taiao motuhake, pērā i te wā he kōhatu matotoru kei runga i te mata o te urunga turanga kirikiri, hei ārai i te wero i te geomembrane ārai-mimi, me horahia he paparanga angiangi o te onepu whakaranu (3-5cm te matotoru) ka hurihia ki runga i te mata o te urunga turanga kirikiri. Me kapi katoa te mata o te urunga turanga kirikiri e te paparanga onepu, ā, kaua he kirikiri he rahi matūriki neke atu i te 4mm i roto i te paparanga onepu. I te wā e hanga ana i roto i ngā taiao makariri, pāmahana teitei rānei, me mahi ngā mahi tiaki tika, pērā i te hononga whakamahana me te whakarerekē i te wā hanga, kia kore ai e pāngia te kounga o ngā hononga e te taiao.
E kitea ana i runga ake nei, ko te maimoatanga hononga o te kupenga waikeri hiato-toru-ahu he hononga matua i roto i te tukanga hanga, e pā tika ana ki te pānga waikeri me te pumau whānui o te kupenga waikeri. Mā te whai i ngā whakaritenga o te whakatikatika ahunga hononga, te whakamutu me te taupatupatu rauemi, te whakamahi hononga, te whakapiri i ngā papanga whenua taupatupatu me te maimoatanga taiao motuhake ka taea te whakarite i te kaha me te pumau o ngā hononga me te whakapai ake i te whai huatanga o te waikeri me te roa o te mahi o te kupenga waikeri.
