Ukukhetha i-vibrator yekhonkrithi efanelekileyo kufana nokukhetha izihlangu ezifanelekileyo kwindawo yokwakha. Eyona inkulu ayisoloko iluncedo kakhulu. Intloko ye-poker enkulu ingabonakala inamandla kwikhathalogu, kodwa ukuba ayikwazi ukudlula kwi-reinforcement eqinileyo okanye ifikelele ezantsi kwe-pour, ayiyi kuwenza kakuhle umsebenzi. I-poker encinci, kwelinye icala, ingangena kwiindawo ezimxinwa ngokulula, kodwa ifuna iindawo zokufaka ezingaphezulu kunye nexesha elingakumbi lokusebenza.
Esi sikhokelo sokuthenga i-vibrator yekhonkrithi sichaza indlela yokukhetha imodeli efanelekileyo ngokwembono yendawo yokusebenza esebenzayo. Endaweni yokujonga amandla emoto kuphela, abathengi kufuneka bathelekise ubungakanani be-poker, ubude be-shaft, umthombo wamandla, i-vibration frequency, isithuba sokufakwa kunye neemfuno zokugcinwa. Kwabakhi, abathengisi, iinkampani zokuqeshisa kunye namaqela okuthenga, le ndlela inceda ekunciphiseni i-honeycomb, ukuphucula uxinano lwekhonkrithi kunye nokuphepha ukuthenga izixhobo ezibonakala zintle ephepheni kodwa zisokola kwikhonkrithi yokwenyani.
Umatshini wokudlidliza wekhonkrithi ususa umoya ovalelekileyo kwikhonkrithi entsha. Xa ikhonkrithi igalelwa, iipokotho zomoya zihlala phakathi kwe-aggregate, i-samente paste kunye ne-reinforcement. Ukuba ezo pokotho zomoya zihlala ngaphakathi kwesakhiwo, isiphumo sinokuba yi-honeycomb, iindawo ezibuthathaka kunye nokugqitywa kakubi komphezulu. I-concrete vibrator ithumela ukudlidliza kumxube, ivumela amaqamza omoya ukuba anyuke ngelixa udaka lujikeleza ilitye kunye ne-rebar.
I-vibrator kufuneka icinezele ikhonkrithi, ingayishukumisi phezu kwefomwork. Le yimpazamo eqhelekileyo kwindawo. Ukuba umqhubi usebenzisa i-poker njengecephe kwimbiza yesobho, ikhonkrithi ingahlukanisa, kwaye akukho mntu ufuna isuphu yekhonkrithi enamatye ezantsi kunye nentlama enamanzi phezulu. Ngokutsho kwe- Isikhokelo solwakhiwo lwekhonkrithi yeCaltrans , ikhonkrithi kufuneka inyikinyiswe ide i-mortar namanzi anyibilike aye kumphezulu, kwaye ukunyikima ngaphaya kwaloo ndawo akufuneki okanye akufuneki.
Eyona ndlela isebenzayo yokukhetha i -concrete poker vibrator kukuqala ngesakhiwo. Jonga isithuba sokuqinisa, ubunzulu bokuthululwa kunye nemilo yefomwork ngaphambi kokukhetha intloko ye-poker.
