Maanta, balakoonka ayaa durba joogsaday inuu noqdo qol adeegsi ah oo loogu talagalay bakhaarada bakhaarada oo kala duwan weli ama aan loo baahnayn waxyaabo gaar ah (si fudud loogu hadlo qashinka, taas oo ka xun tahay in la tuuro). Waqtiyadeena wax ku oolka ah, inbadan milkiileyaal badan oo guryo badan ayaa u arkaa ikhtiyaar ahaan in la kordhiyo mitirka labajibbaarane ee dagaalka.
Si tan loo sameeyo, waa la diiriyaa. Si kastaba ha noqotee, sababtuna tahay in dawladaha kuleylka ah ee aadka loo soo bandhigay suuqa casriga ah, aad bay u fududahay in qalad lagu sameeyo xulasho, taas oo aad uga baqi karta inay saameyn ku yeeshaan xilliga qaboobaha.
Noocyada dahaarka ee Parapet
"Buundada ugu weyn" qabow "balakoonka diiran waa baarajoog. Sidaa darteed, waa inay ahaato mid si sax ah si ay u bixiso feejignaanta ugu badan marka aad ka shaqeyneyso abuuritaanka wareegga kuleylka ee balakoonka.
Waa suurta gal in lagu xakameeyo xaraashka iyadoo la adeegsanayo agabyo kala duwan. Maanta, cayrinta kuleylka soo socda ayaa badanaa la isticmaalaa:
- Styrofofoam;
- Pentolshow
- Penoplex;
- Minjata.
Xulashada dahaarka ayaa si toos ah u saameyneysa tilmaamayaasha ugu badan ee laga jaro heerkulka jiilaalka ee gobolkaaga.
Sidaa darteed, maahan lagama maarmaan in si indho la'aan ah loo raaco talooyinka sayidyada guryaha lagu sameeyo ee magaalooyin kale. Tixgeli waxa dhumucda ee qashin-qubka ay ku fiicnaan doonto kiis kasta.
Wada-tashiga ku saabsan jiritaanka kuleylka ee maaddada
Isbarbardhiga tayada tayada
Tilmaanta farsamada ee ugu weyn ee loogu talagalay qalabka kuleylka kuleylka ayaa ah midhaynta kuleylka. Xaqiiqda ah in tiradaasi uu ka sarreeyo, kuleylka yar ayaa awood u leh inuu haysto qalabkan. Xannibaadda kala duwan ayaa leh xasaasiyad kaladuwan oo kala duwan. Waxaan soo bandhignay liis ku saabsan waxyaabaha ugu badan ee kuleylka kuleylka ee ugu badan ee muujinaya tilmaamayaasha qaab-dhismeedka gaarka loo leeyahay.
- Dhoobo dhoobo ah - laga bilaabo 0.110 ilaa 0.210;
- Dhogor macdanta - laga bilaabo 0.045 illaa 0.085;
- Xumbo iyo xumbo polystyrene - laga bilaabo 0.04 ilaa 0.05.
Calaaladaha xumbada leh waxay leeyihiin astaamaha ugu fiican
Sida laga arki karo xogta la siiyay, tusayaasha ugu fiican ee xinjiriinta kuleylka leh waxay leeyihiin xumbo. Laakiin, tusaale ahaan, muxuu dhumucdii ugu fiicnaa inuu lahaado lakabkiisa magaalooyin kala duwan oo dalka ah? Ka dib oo dhan, tusayaasha cimilada ee wadankeena gaboobay ayaa gabi ahaanba ka duwan, xaqiiqda ah in ay ku habboon tahay xeebta Badda Madow ama Crimea ay gebi ahaanba ku filneyn Norilsk ama Yakutsk.

Meesha juquraafi ahaaneed iyo heerarka dhismaha
Tilmaamayaasha cimilada ayaa ku tiirsan damaca galinta caabbinta lagama maarmaanka u ah qabowga derbiga dhismaha ee deegaanka. Heerarkan hoostooda, xaraashka xiisaha leh ayaa gabi ahaanba dhacaya, maadaama ay ciyaareyso doorka derbiga dibedda ee balakoonka.
Marka, sida laga soo xigtay heerarkan dhismaha, iska caabbinta lagama maarmaanka u ah derbiga kuleylka ee magaalooyinka kala duwan ee Ruushka waa sida soo socota (inta mitirrada cubikada ee Celsius / Watch):
| Sochi | 1,8. |
|---|---|
| Krasnodar | 2,4. |
| Vollograd | 2.9 |
| St. Petersburg | 3,2 |
| Moscow | 3,3. |
| Yekaterrinburg | 3.7. |
| Irkutsk | 4.0 |
| Magacnad | 4,3. |
| Yakutsk | 5.3 |
Xisaabinta dhumucda ugu yar ee qashin-qubka
Ogaanshaha heerarka dhismaha ee loogu talagalay dahaarka derbiyada magaaladooda si fudud ayaa loo xisaabin karaa, waa maxay dhumucda mid ama dahaar kale oo dahaar ah ay tahay inuu jiro dahaarta. Isku-darka loo yaqaan 'The Pefficient of the-da-ku-noolaanshaha waxaa lagu muujiyaa xarafka r waxaana loo xisaabiyaa iyadoo loo eegayo qaaciddada soo socota r = d / k, halkaas oo D uu yahay dhumucda qafiifka, iyo k waa kuwa loo yaqaan' them-ka '. Ku saabsan sida loo xisaabiyo dhumucda qashinka, ka fiiri muuqaalkan:
Iyada oo ku saleysan qaaciddadaas, waxaan isku dayi doonnaa in aan go'aan ka gaarinno dhumucda dahaarka ee xumbo iyada oo la raacayo kuleylka wadnaha ee tilmaanta heerkulka 0.05 ee Irkutsk (iska caabbinta loo baahan yahay waa 4.0). Marka loo eego, d = r * k = 4 * 0.05 = 20 mm. Waa dhumuc weyn oo xumbo ah oo la oggol yahay in la oggol yahay marka lagu daro dahaarka kuleylka ee maqaarka balakoonka. Ogaanshaha isku-darka kuleylka kuleylka ee hal ama dahaar kale, oo kaashanaya caanoboorahan waxaad si fudud u heli kartaa dhumucda qafiifka ah ee aad si fudud u isticmaali karto.
