Papa waikeri me te waikeri hiato a Hongyue
Whakaahuatanga Poto:
He pereti waikeri ātete-wai me te waikeri whakakotahi e whakamahi ana i tētahi pereti kirihou mahi toi motuhake e kapi ana i te anga oko, e hanga ana i te kiriuhi anga piko, he anga tonu, he āputa toru-ahu me te teitei tautoko kua whakaritea, ka taea te tu atu i te teitei roa, kāore e taea te whakaputa i te ahua rerekē. Ka hipokina te tihi o te anga ki te paparanga tātari geotextile, kia kore ai e aukatia te awa waikeri nā ngā mea o waho, pērā i ngā matūriki, i te whakakī raima rānei.
Whakaahuatanga Hua
Ko te papa wai-ātete me te waikeri hiato he mea hanga mai i te kotahi, e rua rānei ngā paparanga o te geotextile kore-whatu me te paparanga o te geonet hangai-toru-ahu. He whānui te mahi a te "tātari whakamuri-waikeri-manawa-tiaki". Nā tēnei hanganga ka pai te mahi a te papa wai-ātete me te waikeri hiato i roto i ngā kaupapa maha, inā koa i roto i ngā kaupapa waikeri pērā i ngā rēriwe, ngā huarahi tere, ngā kauhanga, ngā kaupapa ā-tāone, ngā puna wai, me te tiaki pari.
Ngā horopaki tono
He whānuitia te whakamahinga o ngā papa wai me ngā papa rerenga wai hiato i roto i ngā momo mara hangarau:
1. Ngā rerewē, ngā huarahi tere, ngā kauhanga, ngā kaupapa ā-tāone: e whakamahia ana mō te waikeri me te tiaki.
2. Te parenga o te puna wai me te pari: e whakamahia ana mō te whakakaha me te tiaki.
3. Te maimoatanga ngohengohe o te turanga, te whakapakari i te papa rori, me te tiaki pari: te whakapai ake i te pumau me te pānga o te rerenga wai.
4. Whakakaha i te tautoko o te piriti, te tiaki i ngā pari takutai moana: te ārai i te horo me te tiaki i ngā hanganga.
5. Te whakato i te tuanui o raro whenua me te whakato tuanui: whakamahia hei ārai wai me te tango wai, hei tiaki i te hanganga.
Ngā Āhuatanga Mahi
1. Te kaha o te rerenga wai: he rite ki te pānga rerenga wai o te rerenga wai kirikiri kotahi mita te matotoru.
2. Kaha kume teitei: ka taea te tu atu i te kawenga pēhanga teitei, pērā i te kawenga pēhanga 3000Ka.
3. Ātete ki te waikura, te ātete ki te waikawa me te kawakore: he roa te ora mahi.
4. Hanganga watea: whakapotohia te wā hanga me te whakaiti i ngā utu.
5. Ngāwari pai: ka taea te piko i te hanganga me te urutau ki ngā whenua uaua.
