Kulwakhiwo lobunjineli, kukho ikhonkco elibalulekileyo, ukusetyenziswa kweejenereyitha zomphunga wokunyanga umphunga wekhonkrithi engaphambili. Ijenereyitha yomphunga ebambekayo ifaneleka ikakhulu kuloliwe ohamba ngesantya esiphezulu, uhola wendlela, ukwakhiwa kwebhulorho, amacandelo ekhonkrithi, imiqadi yebhokisi, imiqadi ye-T, imiqadi eqhubekayo, imiqadi ye-U kunye ne-cast-in-place, i-cast-in-place okanye ukugcinwa kwekhonkrithi engaphambili. imisebenzi yeedokhi kunye neendlela zokuhamba.
Ubushushu obulawulwayo bokunyanga emva kwephakheji yokunyanga ikhonkrithi yangaphambili
Kumxholo wokuphunyezwa kolwakhiwo, ukunyangwa komphunga kuye kwaqatshelwa ngokuthe ngcembe kulwakhiwo lweeprojekthi ezinkulu. Kulwakhiwo lwebhulorho yanamhlanje, iijenereyitha zomphunga zisebenzisa umphunga ukufudumeza ikhonkrithi, okubangela ukuba ikhonkrithi ibe lukhuni ngokukhawuleza kumaqondo obushushu aphezulu (70~90°C) kunye nokufuma okuphezulu (malunga ne-90% okanye ngaphezulu).
Ukunyanga umphunga kunokuphucula ngokufanelekileyo umgangatho weebhokisi zebhokisi zekhonkrithi, ukunciphisa ixesha lokwakha, kwaye uqinisekise ngokungqongqo umgangatho weebhokisi zebhokisi. Ijenereyitha yomphunga yeNobeth ikhuselekile, inobuhlobo nokusingqongileyo, kulula ukuyisebenzisa, iselfowuni, kunye nokusebenza okuzenzekelayo ngokupheleleyo ukufezekisa “ukugcinwa okungajongwanga, okuzenzekelayo”, abona benzi bejenereyitha bomphunga kwimarike bonke bajonga ukunyanga ikhonkrithi njengenye yeemarike abajolise kuzo. zininzi iimeko zesicelo ezivuthiweyo.
Ukugcinwa kwebhulorho kwangaphambili
Xa usebenzisa ifilimu yeplastiki ukunyanga, iindawo eziveziweyo zekhonkrithi kufuneka zigqunywe ngokuqinileyo ngeplastiki yeplastiki ukuqinisekisa ukuba kukho amanzi okudibanisa kwi-plastic sheeting ukufezekisa injongo yokunyanga okufumileyo. Kwiindawo ezinqongopheleyo zamanzi kunye nezakhiwo ezide ezinzima ukunkcenkceshela kunye nokugcinwa, isisombululo sempilo yeplastiki yokutshiza ifilimu ingasetyenziselwa ukugcinwa. Ngokuqhelekileyo, iiyure ezi-2 ukuya kwezi-4 emva kokuba ikhonkrithi igalelwe, xa amanzi ophayo esanda kusasazwa kwaye akukho manzi adadayo, unokutshiza isisombululo sezempilo sefilimu ebhityileyo xa kungekho minwe kwikhonkrithi. Akukho mntu uvunyelwe ukuba ahambe kwikhonkrithi de amandla ayo afikelele kwi-1.2MPa. Ngokuqhelekileyo, ukunyanga umphunga kubushushu obumalunga nama-65°C kuyacetyiswa.
Ingaba ukunyangwa komphunga kwikhonkrithi kulungile okanye akunjalo? Ngokuqhelekileyo, ikhonkrithi inokufikelela ngokukhawuleza amandla afunekayo phantsi kweemeko zokushisa okuphezulu kunye nokufuma. Ngenxa yeemeko ezinqongopheleyo kwisiza sokwakha, amacandelo asele enziwe ngaphambili angasebenzisa umhlaba wethutyana okanye imingxuma yokulungisa engaphantsi komhlaba, egqunywe ngesigqubuthelo esikhuselayo okanye iseyile elula okanye iseyile. Ukugcinwa kwekhonkrithi yinxalenye ebaluleke kakhulu yenkqubo yokwakha ikhonkrithi kwaye ihambelana ngokuthe ngqo nomgangatho wokwakha weprojekthi yonke.
