Masiku ano, khonde latha kale kukhala chipinda chothandizira zinthu zosiyanasiyana koma osafunikira (kungoyankhula zinyalala, zomwe ndikupepesa kuti muponye). Mu nthawi yathu yothandiza, eni ochulukirapo komanso ochulukirapo amawona ngati njira yowonjezera mita yambiri.
Kuti achite izi, amatenthetsedwa. Komabe, chifukwa cha zovuta zazikulu zamafuta otembereredwa pamsika wamakono, ndizosavuta kulakwitsa posankha zochita, zomwe zimangowopa kukhudzana ndi nyengo yozizira.
Mitundu ya Kukupitira kwa Parset
"Bridge" yayikulu "pa khonde lotenthedwa ndi linga. Chifukwa chake, iyenera kukhala yoyenera kulipira chidwi mukamagwira ntchito pa khonde la khonde.
Ndikotheka kugwirizanitsa pampando pogwiritsa ntchito zinthu zosiyanasiyana. Masiku ano, kutentha zotsatirazi kumagwiritsidwa ntchito kawirikawiri:
- Strerofoam;
- Penophol;
- Penplex;
- Minvata.
Kusankha kwamphamvu kumakhudza mwachindunji zisonyezo zowerengera zamatenthedwe otentha m'chigawo chanu.
Chifukwa chake, sikofunikira kutsatira mwadzidzidzi malingaliro a ambuye akodzola ku mizinda ina. Ganizirani momwe makulidwe makulidwe a khondeyo amakhala oyenera pankhani iliyonse.
Zogwirizana ndi mawonekedwe a zinthuzo
Kufanizira kwa Makhalidwe Abwino
Chizindikiro chachikulu chaukadaulo cha zinthu zotchinga zamagetsi ndizomwe zimayenda bwino. Chowonadi chakuti chiwerengerochi ndi chachikulu, kutentha kochepa kumatha kugwirizira izi. Kufukula zosiyanasiyana kumakhala ndi mawonekedwe osiyanasiyana othandiza. Tikuwonetsa mndandanda wazinthu zopindika kwambiri zamagetsi zomwe timapanga ndikuwonetsa mawonekedwe apadera.
- miyala ya dongo - kuchokera pa 0.110 mpaka 0.210;
- Ubweya wa mchere - kuyambira 0,045 mpaka 0.085;
- Chithovu ndi polystyrene chithovu - kuyambira 0,04 mpaka 0.05.
Pulasitiki ya thovu ili ndi katundu wabwino kwambiri
Monga momwe mungawonedwe kuchokera ku data yomwe yaperekedwa, mawonekedwe abwino kwambiri otchingira mikangano ali ndi thovu. Koma, mwachitsanzo, ndi makulidwe oyenera omwe angakhale ndi gawo losiyanasiyana m'mizinda yosiyanasiyana ya dzikolo? Kupatula apo, zizindikiro zokhala ndi nyengo m'dziko lathuli ndizosiyana kwathunthu, komanso kuti ndizoyenera kunyanja yakuda kapena ku Crimea sikhala yokwanira kwa Norilsk kapena Yakutsk.
Nkhani pamutu: yadutsa m'magetsi, ndi chiyani?
Malo okhala ndi miyezo yomanga
Kuchokera pamalonda ojambula kumadalira chizolowezi chowongolera kukana kofunikira pakuzizira kwa khoma la nyumbayo. Pansi pa miyezo imeneyi, pakhosi yokhazikitsidwa imagwera kwathunthu, chifukwa imasewera gawo la khoma lakunja pakhonde.
Chifukwa chake, malinga ndi miyezo yomanga, kukana kofunikira kwa khoma losinthitsa m'mizinda yosiyanasiyana ya Russia ndi motere (m'zigawo za cubic meters a Celsius / Watt):
| Sochi | 1,8. |
|---|---|
| Krasnodar | 2,4. |
| Kachulidwe | 2.9 |
| St. Petersburg | 3,2 |

Kuwerengera kwa kukula kochepa kwa mphamvu yamatenthedwe
Kudziwa miyezo yomanga ya makoma a mzinda wawo kumatha kuwerengedwa mosavuta, kodi makulidwe amodzi ndi amodzi kapena kusokonekera kwina kuyenera kukhala kuti pabwalo ndi chipongwe. Kuphatikizika kwa matenthedwe kumadziwika ndi chilembo cha r ndipo chimawerengedwa malinga ndi mtundu wotsatira r = D / k, pomwe D ndi makulidwe ake, ndi k ndi mawonekedwe ake othandiza. Za momwe mungawerengere makulidwe a chimbudzi, yang'anani mu kanemayu:
Kutengera mtundu uwu, tiyesa pafupifupi kudziwa kukula kwa chithovu ndi thonje ndi chizindikiritso cha majerrmal (kukana kwa Irkutsk (0). Molingana, D = R * K = 4 * 0.05 = 20 mm. Ndiwo chithovu chambiri chomwe chizikhala chovomerezeka chokwanira pomwe matenthedwe a khonde. Kudziwa zochulukitsa zamafuta a chimodzi kapena zingapo, mothandizidwa ndi fomulayi mutha kupeza bwino kwambiri zakuthupi zomwe mungathe mosavuta.
