Kukho imigangatho yokwamkelwa esi-8:
[1] Lawula ngokungqongqo umthwalo wokwakhiwa kophahla, umgangatho kunye neqonga, ungagqithisi umthamo wokuthwala iiplanga, iitrasi, umgangatho kunye nebhodi yephahla.Emva kokubunjwa kweeyunithi zendawo, i-gap phakathi komgangatho wekholomu kunye nomgangatho ophezulu wesiseko kufuneka uchithe ngexesha elifanelekileyo ikhonkrithi yamatye, i-grouting, njl.
[2] Iinkcukacha zeziqhoboshi ezifana neshafti yokubeka, shaft yesiseko, ubude kunye nebholithi yeankile kufuneka zihlangabezane neemfuno zoyilo ezifanelekileyo.Ukutenxa okuvumelekileyo komgangatho wokuxhasa isiseko yi-3 mm, ukutenxa okuvumelekileyo kweziko le-anchor bolt yi-5 mm, ukutenxa okuvumelekileyo kweziko lomngxuma ogciniweyo yi-10 mm, kwaye ukutenxa okuvumelekileyo kobude obuveziweyo bebholithi ye-ankile yi-0-30 mm.
[3] Ngokutsho kwekhowudi yokwamkela ubunjineli besakhiwo sensimbi, indawo yokudibanisa kufuneka ibe ubuncinane i-70% ye-inlet seam, kwaye umgama phakathi kwee-side seams akufanele udlule i-0.8mm.
[4] Emva kokuba amacandelo angena kwindawo, khangela ngexesha elifanelekileyo ukunyamezela kokuphakama okufanelekileyo kokugoba okuthe nkqo kunye nokuthe tye kwe-truss yentsimbi kunye namalungu oxinzelelo, khangela ukuphambuka kokuhamba okuthe nkqo kunye nokuthe tye kwekholamu yentsimbi kunye nokuma kwekholamu, kwaye ngokunjalo. kufuneka ibe ngaphakathi kwexabiso elivumelekileyo lokutenxa kwiikholamu zamacandelo amaninzi.
[5] Ukutenxa ngokuthe nkqo kwesakhiwo sentsimbi ye-crane beam ingaphakathi kwe-1/5 yobude obupheleleyo be-crane, kunye nokuphambuka okuvumelekileyo kokuphakama kwe-vector yokugoba ngaphakathi kwe-1/1500.
[6] Ukufakwa kwezakhelo zentsimbi yesakhiwo kufuna ukusetyenziswa kweentambo zomoya, ii-winches kunye nezinye izixhobo zokuqinisekisa ukuzinza kwayo.Emva kofakelo olupheleleyo, uluhlu lweenkqubo zenkxaso ezifana nezixhaso zekholomu, izibonda zokubopha, kunye nezixhaso zophahla oluthe tye kufuneka zifakwe ngexesha.Ukuba kunokwenzeka, ii-purlins zephahla zingafakelwa, oko kukuthi ukuzinza kwesakhelo sensimbi yonke.
[7] Kwakhona kufuneka uhlolisise ukuxhaswa kwephahla, ukuxhaswa kwe-diagonal, inkxaso ye-diagonal kunye nenkxaso yomkhono wenkxaso, ukubona ukuba ukuxhaswa kwodonga, ukuxhaswa kwe-diagonal, uxhulumaniso lwenkxaso lufakwe, kodwa kwakhona ujonge uxhulumaniso kunye nenani lekholomu yensimbi.
[8] Khangela ngexesha elifanelekileyo indawo yokudibanisa kunye nenani lenkxaso ethe tye, intonga eqinile yokubopha kunye nenkxaso yentsika yophahla.
