Isikrufu sokumisa amanzi samacandelo amathathu
Ingcaciso yeMveliso
>>>
Uhlobo lwe-vertebral body stop stop screw lunokwahlulwa ngokufanelekileyo lube ngamacandelo amathathu: iintonga ezimbini zangaphandle kunye nentonga enye yangaphakathi. Inesakhiwo esilula kunye nokusetyenziswa okufanelekileyo. Kwaye intonga yangaphandle inokuphinda isetyenziswe emva kokuchithwa. Ekwakhiweni kamva, kuphela icandelo eliphakathi kwe-screw kufuneka lithengwe, elineenzuzo zokunciphisa inkunkuma kunye nokunciphisa iindleko zezinto eziphathekayo; Kwaye uphucule ukusebenza kakuhle kunye nomgangatho wokwakhiwa kwekhonkrithi. Inxalenye ephakathi yentonga yangaphakathi idityaniswe ngendandatho yokumisa amanzi, kwaye iziphelo ezimbini zifakwe intambo. Ubude bentonga yangaphakathi bunqunywe ngokobunzima besakhiwo sekhonkrithi esincinci. Kwinkqubo yokususwa kwe-formwork, susa kuqala intonga yangaphandle ye-screw, uze ususe i-formwork. Iformwork ayinalahleko kwaye yonga imali kunye nomsebenzi
