Ko te painga me te tono o nga Roopu Punga Whaiaro

Ko te mahi o te rakau punga torino hollow grouting he grouting, no reira ka kiia hoki he paipa grouting.Ka taea te huri i roto i te mahere whanui kia tutuki ai te pehanga tuatahi.I raro i te pehanga, ka rere atu te slurry o roto, ehara i te mea he pumau tonu ki runga i a ia ano, engari ka uru ano ki te kohao punga i te wa e puhake ana te slurry, ka whai waahi ki te whakakotahi i te toka huri noa.Kei a ia ano nga painga ki te tono me te whakamahere, na reira ka taea e ia te whakaatu i ona ake painga ki te tono:

1, Kei raro i tenei paanga ka taea te whakatutuki i te paanga tautoko tere tuatahi ka taea te whakahaere pai i te whakarereketanga o te toka a tawhio noa ka taea te whakatutuki i te paanga pai.

2、 Ka whakamahia he huarahi tuwhera ki te whakamahere, te whakauru i nga rakau punga me nga putorino.Ko tenei ahua o te whakamahere he nui nga painga.Mena he putorino tuku iho, ka ngaro pea na te toia whakamuri me te whakamuri, kaore e puta he ahuatanga penei.

3, Ka taea e ia te whakapai ake i te kounga o te kaupapa, he mea tika na te mea ka taea e ia te whakatutuki i te nui o te whakakii i te wa e pupuhi ana, me te taha o te pupuhi, ka taea te whakatutuki i te painga o te pupuhi.

4. He pai te noho koretake.Na te taapiri o etahi atu taputapu i te wa e whakamahia ana, ka piki ake tona koretake, ka taea e te slurry te takai i te rakau punga tuwhera katoa.Na tenei ka kore e puta te waikura i te wa e whakamahia ana ka taea te whakamahi mo te wa roa.

5、 He tino watea hoki i runga i te taputapu, he mea tino nui hoki.I te wa e watea ana i runga i te taputapu, ka taea te whakapoto i te waa patuiro me te wa hanga.I te taha o te taputapu, kare e hiahiatia he wiri hei whakatutuki i nga whakaritenga o te nati taputapu me te papa.
