Ubusika yinkathi enzima kakhulu yokwakha ukhonkolo. Uma izinga lokushisa liphansi kakhulu, isivinini sokwakha ngeke sincishiswe nje kuphela, kodwa i-hydration evamile yekhonkrithi izophinde ithinteke, okuzonciphisa ukukhula kwamandla ezingxenyeni, ezisongela ngokuqondile ikhwalithi yephrojekthi kanye nenqubekelaphambili yokwakha. Indlela yokunqoba lesi sici esingesihle sekuyinselelo enkulu ebhekene nokwakhiwa konjiniyela njengamanje.
Ngenxa yohlelo oluqinile lokwakha nemisebenzi esindayo, ubusika sebuzongena. Ukuphendula izici zesimo sezulu sendawo, ukuze kuqinisekiswe ikhwalithi nenqubekela phambili yephrojekthi, amanye amayunithi ayalele amajeneretha kakhonkolo amaningi e-Nobis ephulukisa isitimu ukuba alahle indlela evamile yokwelapha yokufafaza ngamanzi futhi asebenzise indlela yokwelapha umusi ukuze afinyelele ukulawula okuzenzakalelayo. ukwelapha umusi ukhonkolo.
Isizathu silula. Nakuba indlela yendabuko iphumelela, ukuthembela kuphela ekugcinweni kokushisa kokusabela kwe-concrete hydration ngemva kokugqoka akukwazi ukuqinisekisa ibhalansi yokushisa nokuzinza. Amandla kakhonkolo akhula kancane futhi ikhwalithi yephrojekthi ijwayele izinkinga. Kodwa-ke, kuyafaneleka ukusebenzisa ukujikeleza kwe-steam ukuze kugcinwe ibhalansi nokuzinza kwezinga lokushisa kanye nomswakama, nokusebenzisa izici zayo ezifanayo zokulondoloza ukuze kuzuzwe ukulawula okuphumelelayo kwekhwalithi yesondlo.
Ubuchwepheshe bezempilo be-Steam
Ububanzi bokusebenza: Lapho izinga lokushisa langaphandle lingaphezu kuka-5 ℃, kodwa ngenxa yesikhathi eside sendlela yokuphulukisa yemvelo yokufafaza kwamanzi, ukuze kuthuthukiswe izinga lokusebenzisa izinto ezithengiswayo njengesikhunta nezisekelo futhi kuthuthukiswe ukusebenza kahle kokukhiqiza, indlela yokwelapha isitimu kufanele isetshenziselwe ukuqeda umthelela wezinto ezihlukahlukene ezimbi zemvelo.
Ukuhlelwa kwamapayipi omusi: Ukwakhiwa kukakhonkolo kwenziwa ekwindla. Ukhonkolo ngokwawo ulahlekelwa umswakama ngokushesha, ikakhulukazi phakathi nosuku. Kunconywa ukuthi uthele futhi umboze ngezigaba; beka amapayipi esitimu acutshungulwe kusenesikhathi ngaphambi kokumbozwa, bese uwabeka ekugcineni kweshede lokupholisa isitimu ngemva kokuba esembozwe ngokugcwele. Vula isitimu ukuze uthole ukunakekelwa kwezempilo.
【Isigaba sangaphambi kokulinywa】
Ngaphansi kwezimo ezivamile, isikhathi sokuphulukiswa kwangaphambili kokuphulukiswa kwesitimu sikakhonkolo amahora angu-2, okuyisikhathi sokuphumula kusukela ekuqedeni ukuthululelwa kukakhonkolo ekuqaleni kwesitimu. Ekwindla, ngoba ukhonkolo ngokwawo ulahlekelwa amanzi ngokushesha, ihora elingu-1 ngemva kokuqala kwenkathi yokuphulukisa, ijeneretha ye-steam isetshenziselwa ukuthumela isitimu endaweni yokuphulukisa umusi izikhathi ezintathu, isikhathi ngasinye imizuzu engu-10.
【Isigaba sokushisa esiqhubekayo】
Isikhathi sokushisa esingashintshi isikhathi esiyinhloko sokukhula kwamandla kakhonkolo. Imvamisa, imingcele yezobuchwepheshe eyinhloko yenkathi yokushisa engashintshi yilezi: izinga lokushisa elingashintshi (60℃~65℃) kanye nesikhathi sokushisa esingaguquki esingaphezu kwamahora angu-36.
【Isiteji sokupholisa】Phakathi nesikhathi sokupholisa, ngenxa yokuhwamuka kwamanzi ngokushesha ngaphakathi kokhonkolo, kanye nokuncipha kwevolumu yengxenye kanye nokukhiqizwa kokucindezeleka okuqinile, uma isivinini sokupholisa sishesha kakhulu, amandla kakhonkolo azoncishiswa, futhi ngisho nezingozi zekhwalithi zizokwenzeka; ngesikhathi esifanayo, phakathi nalesi sigaba, uma Ukulahlekelwa kwamanzi Kakhulu kuzothinta i-hydration kamuva futhi ukukhula kwamandla kamuva. Ngakho-ke, phakathi nesikhathi sokupholisa, izinga lokupholisa kufanele lilawulwe liye ku-≤3°C/h, futhi ishede alikwazi ukuphakanyiswa kuze kube yilapho umehluko wezinga lokushisa phakathi kwangaphakathi nangaphandle kweshede ungu-≤5°C. I-formwork ingasuswa kuphela amahora angu-6 ngemva kokususwa kweshede.
Ngemuva kokuvulwa kwezingxenye futhi i-formwork isusiwe, izingxenye zisadinga ukufafazwa ngamanzi ukuze zigcinwe. Isikhathi sokunakekela siyizinsuku ezingu-≥3 kanye nezikhathi ezingu-≥4 ngosuku. Ukwakhiwa okwenziwe ngaphambilini ebusika akukwazi ukungabi nandaba. Ngemuva kokuthululwa kwekhonkrithi, inqubo yokugcinwa ebaluleke kakhulu kufanele yenziwe ukulawula izinga lokushisa kanye nomswakama wendawo yangaphandle yebhokisi lebhokisi ukuze kugwenywe izingozi zekhwalithi ezifihliwe ezibangelwa ukushisa okuphansi kakhulu.
Izinsuku zokuqala ezi-3 emva kokuphothulwa kokuthululwa kwekhonkrithi yisikhathi esibucayi sokuthuthukisa amandla ezingxenye. Izindlela zokwelapha zendabuko ngokuvamile zithatha izinsuku ezingu-7 ukufinyelela izimfuneko zamandla aqinile. Manje indlela yokwelapha i-steam isetshenziselwa ukwelapha. Amandla akhula ngokushesha kunokwelapha okuvamile futhi ukukhula kuzinzile. Iqinisekisa ukuthi ukhonkolo ufinyelela amandla okususwa kwe-formwork ngokushesha ngangokunokwenzeka, unciphisa futhi ulondoloze isikhathi somjikelezo wokwakha, uqinisekisa isikhathi sokwakha, futhi uvumela Ukwakhiwa kweBhuloho Lomfula i-Jiasa kuyashesha futhi.
