1. Imfuneko esemgangathweni yeumbhobho wentsimbi ejikelezayoukupakisha kukupakisha ngokweentlobo kunye nemigangatho phantsi kwesiseko sokupakisha uxolo nokhuseleko. Iindidi ezahlukeneyo zemathiriyeli kufuneka zipakishwe ngokwahlukeneyo ukuthintela udaka kunye nokubola;

2. Thintela izinto ezonakalisayo kwintsimbi ekugcinweni kufutshane nombhobho wentsimbi ejiyileyo;

3. I-bottom of the spiral steel stack yombhobho kufuneka iphakanyiswe, idibaniswe kwaye ibe flat ukuphepha umswakama okanye ukuguqulwa kwezinto;

4. Izinto ezifanayo zifakwe ngokulandelelana kokugcinwa;

5. Amacandelo emibhobho yentsimbi ejikelezayo epakishwe kwindawo evulekileyo kufuneka ibe neemethi zomthi okanye amacwecwe ngaphantsi, kwaye umphezulu wokupakisha kufuneka uthambekele kancinane ukwenza lula ukukhupha amanzi kwaye ubeke ingqalelo kwizinto eziza kubekwa ngqo ukuphepha ukugoba kunye nokuguqulwa;

6. Umphakamo wokupakisha wemibhobho yentsimbi ejikelezayo ayidluli kwi-1.2m yomsebenzi wezandla, i-1.5m yomsebenzi womatshini, kunye ne-2.5m yobubanzi besitaki;

7. Kufuneka kubekho indlela ethile phakathi kwesitaki kunye nesitaki, umjelo wokuhlola ngokuqhelekileyo yi-0.5m, kwaye umjelo wengeniso kunye nenkcitho uxhomekeke kubukhulu bezinto kunye noomatshini bokuhambisa, ngokubanzi 1.5 ~ 2.0m;

8. Intsimbi evulekileyo yentsimbi yentsimbi kunye nentsimbi yesitishi kufuneka ibekwe phantsi, oko kukuthi, umlomo kufuneka ujonge phantsi, i-I-beam kufuneka ibekwe ngokuthe tye, kwaye i-slot surface yentsimbi ayifanele ijonge phezulu. ukuphepha ukurusa ngenxa yamanzi aqokelelweyo;

9. Ukuphakama komzantsi wesitaki. Ukuba indawo yokugcina impahla ikumgangatho wesamente onelanga, umphakamo unokuba yi-0.1m; ukuba ngumgangatho onodaka, umphakamo kufuneka ube yi-0.2 ~ 0.5m. Ukuba yibala elivulekileyo, ukuphakama komgangatho wesamente yi-0.3 ~ 0.5m, kwaye ukuphakama kwesanti kunye nodaka lomhlaba yi-0.5 ~ 0.7m.
