simbi yekuchengetedza mabhodhi
Iyo yakadzamirirwa kudzika kwecasing ichasangana nezvinodiwa zvekugadzira, uye kudzika kwakadzika kuchaita zvinotevera zvinodiwa:
1. Kana iyo casing yakavigwa munyika yakaoma kana mvura isina kudzika, kune iyo isingapindiki pasi pasi, kuvigwa kwakadzika kunofanira kuva 1.0-1.5 nguva yekunze kwekasi, asi kwete pasi pe1.0m; nokuda kwepasi rinopinda pasi rakadai sejecha uye silt, kudzika kwakavigwa kwakafanana nepamusoro, asi Zvinokurudzirwa kutsiva nevhu risingapindiki kusvika risingasviki 0.5m pazasi pemucheto wechubhu inodzivirira, uye dhayamita yekutsiva inofanira kudarika iyo. dhayamita yechubhu inodzivirira ne 0.5-1.0m.
2. Mumvura yakadzika uye murwizi ivhu rakapfava uye gobvu silt layer, mupendero wezasi wechubhu inodzivirira inofanira kupinda mukati mukati meiyo isingapindiki; kana pasina jira risingapindiki, rinofanira kupinda 0.5-1.0m muhurungudo nematombo makuru.
3. Pamibhedha yenzizi inobatwa nekukweshwa, mupendero wepasi wechubhu inodzivirira inofanira kupinda isingasviki 1.0m pazasi pe general scour line. Kune migero yenzizi yakakanganisika zvakanyanya nenharaunda scour, kumucheto kwepasi kwechubhu inodzivirira kunofanirwa kupinda isingasviki 1.0m pasi pemutsetse wenzvimbo.
4. Munzvimbo dzevhu dzakaomeswa nemwaka, mupendero wepasi wechubhu inodzivirira inofanira kupinda kwete pasi pe 0.5m muvhu risina chando pasi pemutsara wechando; munzvimbo dzepermafrost, mupendero wepasi wechubhu inodzivirira inofanira kupinda mukati me permafrost layer isingasviki 0.5 m. 0.5m.
5. Munyika yakaoma kana kuti mvura yakadzika isingasviki 3m uye pasina ivhu risina simba pasi pechitsuwa, casing inogona kuvigwa nenzira yakazaruka, uye ivhu revhu rakazadzwa pasi uye rakakomberedza. iyo casing inofanira kubatanidzwa muzvikamu.
6. Apo cylinder body iri pasi pe3m, uye silt uye ivhu rakapfava riri pasi pechitsuwa harisi gobvu, nzira yakazaruka yekuviga inogona kushandiswa; Kana sando inonyura, nzvimbo yendege, vertical inclination uye yekubatanidza mhando yecasing inofanira kunyatsodzorwa.
7. Mumvura umo kudzika kwemvura kwakakura kudarika 3m, chivharo chekudzivirira chinofanira kubatsiridzwa nepuratifomu yekushanda uye mutungamiri wekufambisa, uye nzira dzekudengenyeka, nyundo, jetting mvura, nezvimwewo zvinofanira kushandiswa kunyura.
8. Nzvimbo yepamusoro yekasi inofanira kuva 2m yakakwirira kudarika mvura yekuvaka kana chiyero chemvura yepasi, uye 0.5m yakakwirira kudarika nzvimbo yekuvaka, uye kureba kwayo kunofanira kuramba kuchizadzisa zvinodiwa zvekukwirira kwevhu revhu mugomba.
9. Nokuda kwechubhu yekudzivirira yakaiswa panzvimbo, kukanganisa kunobvumirwa kwepamusoro pepamusoro ndeye 50mm, uye kukanganisa kunobvumirwa kwekutsvaga ndeye 1%.
