Tau whakarea onepu whakakiato i - te wāhanga e tika ana i roto i te kōwhiringa o te rauemi

Sand whakamahia i roto i te mara ngā o te hanga, na ko te mea nui ki te mohio me pehea ki te tātai i te nui e hiahiatia ana o tenei rauemi. Ki te puta te reira kia inea te i rōrahi, he mea nui ki te tango i ki pūkete te tohu pērā i raungaitinga one ōwehenga (Kaihoko haapotohia). Ko reira mahuinga ia i roto i tenei tatauranga. He nui tenei tohu ki te mārama me pēhea te raungaitinga.

Ko te rōrahi o te rauemi

ka mea a I kia pā tawhā he maha o ngā āhuatanga o waho, pērā i te aratau me te whānuitanga o te hariata. Ki te karo i ngā huringa i roto i te rōrahi o te onepu, ko te mea e tika ana ki te tino tiaki i te reira i te kino pūkaha me te tomo ki o te houku me huānga ke. Tirohia tenei rauemi kia tango te wahi tonu i te fariiraa, na ki te kaiwhiwhi kihai i titau i te kaiwhakarato. E kore te te tātaitanga o tenei tawhā uaua. Ki tenei me whakanuia e te nui tūturu o te rauemi i runga i te tau whakarea o hiri onepu. He he he utu, kua tāuta e GOST 9757-90. e kore e waiho te reira i runga ake i 1.15. Hei whakatau i te nui tūturu e tika ana ki te kawe i roto i inenga o te rōrahi o te tinana, engari e te reira teitei tūturu o te rauemi, nui atu i te taha.

ōwehenga raungaitinga onepu

Tenei tohu, tei runga:

• Temperature me te haumākū. Hei tauira, i roto i te hotoke kia puta kapia to'eto'e. Kei te tuhia hoki ratou rōrahi.
• tikanga o te hariata.
• whakarōpū rauemi nui rite ki GOST 25100-95 me GOST 8736-93 wahi e tohua tona haumākū tūturu me te mātotoru.
• Tei hoki onepu ōwehenga raungaitinga i runga i te wahi i riro ai. Hei tauira, he rerekē te rauemi i te rua i keria i te tāpae.

He mea nui ki te tango ki pūkete te take o te raungaitinga whanaunga o onepu. he tika i roto i te tātaitanga mea tenei ahua. Fele ko reira te ōwehenga o te kiato o te rauemi "maroke" (te kōhiwi). e tenei ki pūkete te ōwehenga raungaitinga onepu (SNP 2.05.02-85) ki te tawhā taua i roto i te whiwhi pūtake.

Tei Tātaitanga i runga i te maha o ngā āhuatanga:

• Mai i nga āhuatanga o te puna, te wahi i whiwhi te rauemi (alluviation waipēhi, he whakapai).
• I runga i te tikanga makariri.
• Mai i te kaupapa waka o te tuku o te rauemi ki te pae whakapanga.
• I te raraunga uruwhenua pūtake. He kua oti te tuhituhi raraunga pērā i te huru o te onepu, tona kiato tūturu me haumākū, me te pera i runga i.

Kaunihera

Hoki te faaotiraa o te tahi atu tohu e tango i te nui e tika ana o te tauira rauemi i te hohonu mata o e pā ana ki 20-25 cm, me te i te iti rawa te 50 cm i te taiepa o te tinana. He mea nui hoki te ako. kia tauira o tenei rauemi i runga i GOST 12071-84. Ano, kia whai ia o ratou he tapanga ◊oku ◊oatu fakataha, i tika nei kia tohua nga raraunga e tika ana. Kia mahara ki e i roto i te tikanga ki te tiaki ia ratou i utu atu i roto i nga mahi, he mea e tika ana te tīmatanga ki te tātai i te nui o onepu. Ko te tino nui i roto i te hanga o rori te tikanga tauwehe raungaitinga onepu, mai pānga ki te kaha hanganga.
