Imibhobho ye-SML, izixhobo kunye neenkqubo zokudibanisa ziveliswa kwaye zihlolwe ngokwe-EN 877

Imibhobho ye-SML, izixhobo zokufaka kunye neenkqubo zokudibanisa ziveliswa kwaye zihlolwe ngokwe-EN 877. Imibhobho ye-SML isikwe kubude obufunekayo ngokuthe ngqo kubasebenzi abasebenza ngezixhobo. Imibhobho kunye nezilinganisi zidityaniswe kunye nezibophelelo ezifanelekileyo zombhobho. Imibhobho ethe tyaba kufuneka ibotshelelwe ngokwaneleyo kuwo onke amathuba kunye namasebe. Imibhobho ephantsi kufuneka ibotshelelwe kumgama ophezulu we-2 m. Kwizakhiwo ezinemigangatho emi-5 okanye nangaphezulu, imibhobho esezantsi ye-DN 100 okanye enkulu kufuneka ikhuselwe ekutshoneni ngenkxaso yemibhobho. Ukongeza, kwizakhiwo eziphakamileyo inkxaso yombhobho kufuneka ifakwe kwisitezi ngasinye sesihlanu esilandelayo. Iipayipi zokuhambisa amanzi zicwangcisiwe njengemigca yomxhuzulane ongafakwanga umthwalo. Nangona kunjalo, oku akubandakanyi umbhobho ukuba ube phantsi koxinzelelo ukuba iimeko ezithile zokusebenza zenzeka. Njengokuba imibhobho yokuhambisa amanzi nokungena komoya iphantsi konxibelelwano olunokwenzeka phakathi kwemibhobho kunye nokusingqongileyo, kuya kufuneka zivuzise ngokusisigxina ngokuchasene noxinzelelo lwangaphakathi nolwangaphandle phakathi kwe-0 ne-0.5 bar. Ukugcina olu xinzelelo, ezo ndawo zombhobho zixhomekeke kukuhamba okude kufuneka zifakelwe ecaleni kwe-longitudinal axis, zixhaswe ngokufanelekileyo kwaye zikhuselekile. Olu hlobo lokulinganisa kufuneka lusetyenziswe nanini na xa uxinzelelo lwangaphakathi olungaphezulu kwe-0.5 bar lunokuvela kwimibhobho yokuhambisa amanzi, njengakwezi meko zilandelayo:

- Imibhobho yamanzi emvula

- Imibhobho kwindawo engasemva kwamanzi

Umbhobho wamanzi wenkunkuma ohamba ngaphezulu komgangatho ongaphantsi kwesinye ngaphandle kokungena

Imibhobho yoxinzelelo kwiimpompo zamanzi amdaka.

Imibhobho engafakwanga nefrimpi ngokuxhomekeke kuxinzelelo lwangaphakathi olunokubakho okanye uxinzelelo olukhulayo ngexesha lokusebenza. Le mibhobho kufuneka ibonelelwe ngesixhobo esifanelekileyo, ngaphezulu kwako konke ukujikajika, ukukhusela izembe ukuba lingatyibiliki lize lahlule. Ukuxhathisa okufunekayo kombhobho kunye nokunxibelelana ngokufanelekileyo kwimikhosi ye-longitudinal kufezekiswa ngokufaka izibopho ezongezelelweyo (umthwalo wangaphakathi umthwalo ukuya kwi-10 bar kunokwenzeka) kumalungu. Ulwazi oluthe kratya malunga nemicimbi yezobugcisa lunokufumaneka kwincwadana yethu yeenkcukacha zobuchwephesha kunye neenkcukacha.
