I roto i te hanganga huarahi, he ngoikore te hononga rori o te papa rori, he maha ngā wā ka puta he taunga koretake, he pakaru o te papa rori me ētahi atu mate nā te urunga o te wai whenua, ngā rerekētanga o ngā rauemi whakakī me te keri, me te hangarau hanga koretake. Ko te whatunga waikeri hiato-toru-ahu he rauemi e whakamahia whānuitia ana hei whakaoti i ēnei raruraru. Nā reira, he aha āna whakamahinga i roto i te papa rori o te hononga tapahi-whakakī?
1. Ngā take o ngā mate me ngā whakaritenga rerenga wai o te papa rori o te hononga tapahi-whakakī
Ko ngā mate o te papa rori e puta mai ana i ngā raruraru e whai ake nei:
1. Te urunga wai whenua me ngā rerekētanga rauemi
Nā te rerekētanga o ngā taumata wai whenua i te hononga i waenga i te wāhi whakakī me te wāhi keri, ka puta he pikinga waipēhi, ka ngohengohe, ka horoia rānei te wāhi whakakī.
2. Ngā hapa o te tukanga hanga
I roto i ngā tukanga tuku iho, he mea noa ngā raruraru pēnei i te keri koretake o ngā kaupae me te kore e ranea te whakakī i te hononga tapahi-whakakī.
2. Ngā painga hangarau o te kupenga waikeri hiato-toru-ahu
1. He pai te mahi whakaheke wai me te ārai-tātari
Ko te kupenga waikeri hiato-toru-ahu he mea hanga mai i te geotextile taha-rua me te matua mata-toru-ahu o waenganui. Ko te matotoru o te matua mata he 5-7.6mm, ko te poreness he >90%, ā, ko te kaha waikeri he 1.2×10⁻³m²/s, he rite ki te paparanga kirikiri matotoru 1m. Ko te awa waikeri i hangaia e ōna rara poutū me ōna rara piko ka taea te pupuri i te kawe wai pumau i raro i te kawenga teitei (3000kPa).
2. Te kaha o te kume me te whakapakari turanga
Ka taea e te kaha kume roa me te kaha whakarara o te kupenga waikeri hiato-toru-ahu te eke ki te 50-120kN/m, ka taea te whakakapi i te mahi whakapakari o ētahi geogrids. Ina whakatakotoria ki te hononga o te whakakī me te keri, ka taea e tōna hanganga matua mata te whakamarara i te kukū ahotea me te whakaiti i te whakataunga rerekē.
3. Te pakari me te watea o te hanga
He mea hanga ki te polyethylene matotoru (HDPE) me te muka polyester, he ātete ki ngā hihi ultraviolet, te waikura waikawa me te kawakore, ā, he roa te ora mō te >50 tau. Nā ōna āhuatanga mama (te taumaha mō ia wāhanga horahanga <1.5kg/m²) ka māmā te whakatakoto ā-ringa, ā-mīhini rānei, ā, ko te pai o te hanganga he 40% teitei ake i ngā paparanga kirikiri tuku iho.
III. Ngā wāhi hanga me te whakahaere kounga
1. Te maimoatanga o te mata o raro
Ko te whānui o te kaupae keri i te hononga o te keri me te keri he ≥1m, ko te hohonutanga he rite ki te paparanga oneone totoka, ā, ko te hapa papatahi o te mata he ≤15mm. Tangohia ngā mea koi kia kore ai e werohia te kupenga waikeri.
2. Te tukanga whakatakoto
(1) Ka whakatakotoria te kupenga waikeri i te taha o te tuaka o te rori, ā, ko te ahunga matua o te kaha he poutū ki te taumata;
(2) Ka whakapumautia te taupatupatu mā te whakarewa wera rewa, mā te whao āhua-U rānei, me te tawhiti o te ≤1m;
(3) Ko te rahi mōrahi o te matūriki o te whakakī i muri i te oneone he ≤6cm, ā, ka whakamahia ngā mīhini māmā hei whakakīkī kia kore ai e pakaru te pūtake o te mata.
3. Te tirotiro kounga
I muri i te whakatakotoranga, me whakahaere te whakamātautau kawe wai (uara paerewa ≥1×10⁻³m²/s) me te whakamātautau kaha taupatupatu (kaha kume ≥80% o te uara hoahoa).
E kitea ana i te kōrero o runga ake nei, ka taea e te whatunga rerenga wai hiato-toru-ahu te whakapai ake i te pumau me te roa o te papa rori hononga whakakī-keri mā roto i ōna painga o te rerenga wai whai hua, te whakakaha kume me te roa.
