| Ushbu hisobda aholi punktida sodir bo’lishi mumkin bo’lgan yong’inni o’chirish usuli va yong’inni o’chirishda ketadigan suv miqdori aniqlanadi. QM va Q 2.04.02-97 da yong’inni vodoprovod tarmog’ida o’rnatilgan maxsus gidrantlar yordamida o’chirish tavsiya etiladi.
O‘t ochirish suv sarfi
O‘t o‘chirish maqsadida ko‘zda tutiladigan xisobiy suv sarfi ichki va tashqi o‘t o‘chirish suv sarflaridan iborat bo‘ladi. Yong‘in sodir bo‘lgan vaqtda o‘t o‘chirish uchun suv, ichki va tashqi gidrantlardan foydalaniladi.
Qyong‘ = qtash + qichk
bunda: qtash = 10l/s (KM va K 2.04.02-97)
qichk =2*2.5=5l/s (KM va K 2.04.01-98)
Suv manbai ko‘pincha yong‘inni o‘chirish uchun kerak bo‘lgan suv sarfini ta’minlamasa o‘t o‘chirish uchun kerak bo‘lgan suv miqdori toza suv rezervuaridan olinadi.
Wyong‘ =qyong‘*n*T*3.6=15*1*3*3.6=162 m3
Bu yerda: Qichki-ichkaridan o’t o’chirish me’yori, binolarning sig’imiga bog’liq holda SNIP II-30-76 dan olinadi.
Qtash-tashqaridan o’t o’chirish me’yori bo’lib, QM va Q2.04.02-97 dan aholi soni va binolarning qavatiga qarab, hamda tashqaridan yong’in o’chirish 6-jadvalning ilovasiga asoslanib 10 l/sek olamiz.
n-bir vaqtning o’zida sodir bo’lishi mumkin bo’lgan yong’inlar soni.n=1
T-yong’in o’chirish uchun ketadigan vaqt. T=3 soat.
Suv ta'minoti variantlari
Suv yеr osti manbasidan olinadi. Yеr osti suvi dinamik sathining chuqurligi yеr sathiga nisbatan 10 mеtrdan ko’p bo’lganda quyidagi sxemani qabul qilamiz.
1 – quvurli quduq 5 – bosimli suv minorasi
2 – I – ko’tarish nasos stansiyasi 6 – suv tashish quvurlari
3 – toza suv rеzеrvuarlari 7 – vodoprovod tarmog’i
4 – baktеrisid moslamasi bilan jihozlangan II ko’tarish nasos stansiyasi
Statik sathni quyidagicha aniqlaymiz:
St.sath=yer sathi-h=376-13=363
Dinamik sathni quyidagicha hisoblaymiz:
Din.sath=St.sath-S=363-13.82
S – suv sathining tushishi
Qsut –sutkalik suv sarfi, m3/sut.
ТnsI –birinchi ko’tarish nasos stansiyasining ish vaqti,Тns1 = 24 soat.
qsol - quduqning solishtirma suv sarfi, l/s.
Quvurli quduq hisobi
Quvurli quduq filtrini hisoblash.
Filtrni turi suvli qatlam jinsiga bog’liq holda QMQ 2.04.02-97 dan maxsus jadvaldan tanlanadi. Filtr suvli qatlamga o'rnatiladi. Filtrning umumiy uzunligi suvli qatlamdan katta bo'lmasligi kerak. Aks holda filtrning FIK kamayib boradi.
Filtrni talab maydoni:
Vkir–filtrga kirish tezligi
Kf=125, qum uchun.
Filtr uzunligi:
=0,2-0.25 –g’ovaklik
d- filtrning diametri
Tanlashimiz mumkin bo’lgan diametrlar:
d=100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm.
Metrda olgan holda: d=0.1m, 0.15m, 0.2m, 0.25m, 0.3m, 0.35m, 0.4m
Nasos markasini tanlash
Nasos markasini tanlash uchun 2 ta asosiy ko’rsatkichni bilishimiz zarur:
Suv sarfi – Q, m3/soat;
Ko’tarish balandligi – H, m;
Nasosning suv sarfi quyidagicha aniqlanadi:
To’la bosimni quyidagicha aniqlaymiz:
Nasos markasi: АTH10-1х4
Q=70 m3/soat;
H=30 m;
FIK=63 %
