Txhawm rau tiv thaiv ntau lub tsev lossis cov vaj tse los ntawm hluav taws, cov kav dej tua hluav taws raug teeb tsa. Nyob rau hauv lub luag haujlwm, muaj ib qho hluav taws kub hydrant, uas muaj kev sib txuas ntawm cov dej tua hluav taws. Raws li qhov yuav tsum tau muaj ntawm SNiPP-30-76, cov kav dej tua hluav taws nrog cov hluav taws tua hluav taws tau teeb tsa hauv cov tsev nyob hauv ntau lub tsev.
Hluav taws kub nruab nrog:
- qhov hluav taws kub uas muaj txoj kab uas hla ntawm tsib caug lossis rau caum millimeters, txuas rau ib ceg ntawm riser;
- hose (lub tes tsho hemp) ntev 10-20 m;
- ceev kaw ib rab phom;
- lub tshuab hluav taws xob nrog cov tshuaj tsuag (ntsiab) nrog txoj kab uas hla ntawm 13 hli, (thiab tuaj yeem ua tau txoj kab uas hla ntawm 16, 19, 22 hli).
Cov hluav taws kub hnyiab tau muab tso rau ntawm theem ntawm 1.35 m ntawm lub plinth hauv cov khoom tshwj xeeb uas sau tias "PC". Paired cranes tau muab tso rau ib sab saum toj ntawm lwm qhov ntawm qhov deb ntawm ib meter saum lub plinth. Zoo li txhua yam khoom siv tua hluav taws, qhov chaw ntawm cov khoom no tau qhia nyob rau hauv txoj kev npaj tiv thaiv hluav taws. Ib daim paib tshwj xeeb tau muab tso rau ze ze: lub qhov hluav taws kub dawb ntawm qhov liabteb.
Yog tias muaj ntau tshaj kaum ob qhov hluav taws kub hauv lub network ntawm cov kav dej tua hluav taws, lawv raug khi thiab txuas rau cov tes hauj lwm nrog ob lossis ntau qhov kev nkag. Tus naj npawb ntawm cov khoom yog txiav txim siab los ntawm thaj chaw irrigation ntawm txhua chav hauv lub tsev. Lub vojvoog ntawm lub crane yog xam los ntawm tus qauv: R=L1 + L2, qhov R yog qhov hluav taws kub hydrant cuam tshuam lub vojvoog, L1 - qhov ntev ntawm lub tes tsho (lub hose) ntawm lub qhov hluav taws kub;
L2 - theem ntawm qhov compact ib feem ntawm lub dav hlau, sib npaug ntawm qhov siab ntawm chav tsev nyob rau hauv uas lub qhov hluav taws kub hydrant ntsia, tab sis tsis tsawg tshaj li rau meters nyob rau hauv lub tsev uas nws qhov siab tsis ncav cuag 50 m, thiab tsis muaj tsawg tshaj li rau meters nyob rau hauv lub tsev. tsawg dua yim meters hauv cov tsev siab tshaj 50 m.
Table 1. Kev siv dej qis tshaj plaws rau kev tua hluav taws hauv lub tsev
| Tsev thiab thaj chaw | Kev siv dej tsawg kawg ib tus kais dej, l/s | Tus naj npawb ntawm cov hluav taws kub hnyiab hauv pem teb | |
| tsev nyob | Txoj kev ntev mus txog 10 m, cov plag tsev 12-16 | 2,5 | 1 |
| Qhov ntev ntawm txoj kev hauv tsev yog ntau tshaj 10 m, cov plag tsev yog 12-16 | 2,5 | 2 | |
| Txoj kev ntev mus txog 10 m, cov plag tsev 16-25 | 2,5 | 2 | |
| Qhov ntev ntawm txoj kev hauv tsev yog ntau tshaj 10 m, cov plag tsev yog 16-25 | 2,5 | 3 | |
| Administrative buildings | Lub peev xwm txog li 25,000 cu. m., cov plag tsev 6-10 | 2,5 | 1 |
| Lub tsev ntim ntau tshaj 25,000 cubic meters. m., cov plag tsev 6-10 | 2,5 | 2 | |
| Lub peev xwm txog li 25,000 cu. m., cov plag tsev ntau tshaj 10 | 2,5 | 2 | |
| Lub tsev ntim ntau tshaj 25,000 cubic meters. m., cov plag tsev ntau tshaj 10 | 2,5 | 3 | |
| Public vaj tse thiab hostels | Ntau cov plag tsev mus txog 10, lub tsev ntim 5000-25000 cubic meters m. | 2,5 | 1 |
| Ntau cov plag tsev mus txog 10, lub tsev ntim ntau tshaj 25,000 cubic meters. m. | 2,5 | 2 | |
| Tus naj npawb ntawm cov plag tsev yog ntau tshaj 10, qhov ntim ntawm lub tsev yog 5000-25000 cubic meters. m. | 2,5 | 2 | |
| Cov plag tsev ntau tshaj 10, lub tsev ntim ntau tshaj 25,000 cubic meters. m. | 2,5 | 3 | |
| Administration and amenity industrial buildings | Vim ntim 5000- 25000 cu. m. | 2,5 | 1 |
| Lub tsev ntim ntau tshaj 25,000 cubic meters. m. | 2,5 | 2 | |
Lub vojvoog ntawm qhov cuam tshuam ntawm qhov hluav taws kub yuav tsum tsis pub tsawg tshaj kaum rau meters (cov tsev hauv qab 50 m) thiab nees nkaum rau meters (cov tsev siab tshaj 50 m). Nyob rau hauv pem teb, hluav taws kub hydrants yog mounted nyob rau hauv xws li ib tug txoj kev uas ib tug taw tes nyob rau hauv lub chav tsev yuav irrigated nrog dav hlau los ntawm tsawg kawg yog ob pab kiag li lawm. Tus naj npawb ntawm cov hluav taws kub ua haujlwm ib txhij thiab cov dej ntws qis tshaj plaws tuaj yeem pom hauv rooj 1.
Thaum siv cov khoom siv tib lub sijhawm, ob lub crane tuaj yeem ntsia tau rau ntawm ib qho riser. Qhov hluav taws kub valve yog mounted nrog ib txoj kab uas hla ntawm 50 mm. Ib lub dav hlau dej xav tau 2.5 l / s lossis 5 l / s, tus naj npawb ntawm cov dav hlau ua ke yuav tsum tsis txhobtshaj yim.
