Yintoni intshukumo ebambekayo?
Ukungcangcazela kwekhonkrithi kuthetha ukusebenzisa isixhobo sokungcangcazela sekhonkrithi okanye isixhobo sokungcangcazela sekhonkrithi ukwenza ikhonkrithi entsha iqine kwaye iqine. Xa kugalelwa ikhonkrithi, isoloko ibamba amaqamza omoya ize ishiye izithuba phakathi kwentlama yesamente nelitye okanye isanti ngaphakathi. Ukuba ezi zithuba azisuswanga, ikhonkrithi ayiyi kuba namandla, kwaye ukuqhekeka kunokuvela kamva. Ukungcangcazela kwenza umxube uzinzise ngokulinganayo, ukutyhala umoya kwaye uvumele intlama yesamente igqume ngokupheleleyo i-aggregate. Oku kudala ikhonkrithi eshinyeneyo nehlala ixesha elide.
Amashishini amaninzi asebenzisa iivibrator zekhonkrithi. Kwiiprojekthi zezindlu, i-vibration iqinisekisa ukuba ii-slabs kunye nemiqadi ithwala imithwalo ngokukhuselekileyo. Ezindleleni kunye neebhulorho, ukungcangcazela kuphucula ukugqitywa komphezulu kunye nokuqina kwexesha elide. Iifektri ze-Precast zixhomekeke kwi-vibration kwiikholamu, imibhobho, kunye neebhloko, ngoko ke yonke iyunithi idibana nomgangatho ofanayo. Nakwiiprojekthi ezinkulu zeziseko ezingundoqo ezifana namadama nezikhululo zeenqwelo-moya, ukungcangcazela linyathelo elibalulekileyo lokuqinisekisa uzinzo.
I-Ningbo ACE Machinery Co., Ltd ineminyaka engama-29 yamava ekuveliseni oomatshini abathembekileyo bekhonkrithi yekhonkrithi yombane kunye nezinye izixhobo zokwakha. Inkampani ineqela layo le-R&D, ukuhlolwa komgangatho ongqongqo kunye namasebe e-QC kunye ne-QA, kunye nokuhanjiswa okukhawulezayo ngaphakathi kweentsuku ezi-7-30. Ngamava okuthengisa kwihlabathi liphela kunye nenkxaso yoqeqesho lwabathengi, oomatshini be-ACE babonelela ngezixhobo ezomeleleyo ezinceda abasebenzi bafumane iziphumo zokungcangcazela ezigqibeleleyo kumazwe amaninzi.
Kutheni usebenzisa i-concrete vibrate?
I-concrete vibrate isusa amaqamza omoya, idibanise umxube, kwaye yenza ikhonkrithi yomelele, igudileyo, kwaye ihlale ixesha elide, inciphisa iintanda kunye namabala abuthathaka.
Ingaba intshukumo yekonkrithi isebenza njani?
Ivibrator ithumela iintshukumo ezikhawulezayo kwikonkrithi entsha. Ukugubha kwenza umoya uphume, kwaye umxube uhlala kwi-dense, mass mass.
Ingaba kufuneka ungcangcazele nzulu kangakanani?
Ubunzulu be-vibration buxhomekeke kuhlobo lwe-vibrator, ubukhulu bekhonkrithi, kunye nobukhulu bentloko ye-vibrator. Kwimisebenzi emininzi, intloko ye-vibrator kufuneka ingene nzulu ngokwaneleyo ukuze isuse umoya kodwa ingachukumisi i-formwork okanye ukuqinisa. Umgaqo omhle kukufaka i-vibrator ukuze ifike malunga ne-25-50 mm ngaphezu kwezantsi lokuthulula. Oku kuqinisekisa ukuba umaleko ongezantsi uhlanganiswe ngaphandle kokonakalisa imivalo yentsimbi okanye ifom.
Xa usebenzisa i-vibrator yangaphakathi, yifake ngokuthe nkqo, yiyeke ihlale kwindawo ye-5-15 imizuzwana, emva koko uyitsale ngokukhawuleza. Ukuba amaqamza ayeka ukunyuka kwaye umphezulu ubonakala ugudile, icandelo lihlanganiswe kakuhle. Ufakelo kufuneka lugqithe malunga nokuphinda-phindwe kabini kwedayamitha yentloko yevibrator. Ngokomzekelo, intloko ye-50 mm kufuneka ifakwe malunga ne-50-100 mm nganye. Le pateni idlulayo iqinisekisa ukuba akukho zithuba ekuxinaniseni.
Amacwecwe amancinci kunye namacandelo angekho nzulu
Kwi-slabs engaphantsi kwe-150 mm ubukhulu, intloko enkulu ye-vibrator inokuba yomelele kakhulu. Endaweni yoko, iintloko ezincinci okanye ii-vibrators ezingaphezulu zisetyenziswa. I-screed eshukumayo okanye i-vibrator ye-beam inokugubungela yonke indawo kwaye inike ukudibanisa okulungileyo. Kwezi meko, ubunzulu abubalulekanga njengokugubungela. Injongo kukususa umoya kunye nomgangatho ophezulu ngaphandle kokusebenza ngokugqithiseleyo umxube.
Ienyawo ezinzulu kunye nezinto ezide
Kwiikholomu, iindonga, okanye iziseko ezinzulu, ukungcangcazela kufuneka kwenziwe ngokwamanqanaba. Beka ikhonkrithi kwiilifti ezimalunga ne-300–500 mm kwaye ungcangcazele umaleko ngamnye ngaphambi kokuba wongeze olandelayo. Faka ivibrator ukuze igqobhoze umaleko wangoku kwaye nje kancinane kumaleko angezantsi. Oku kudibanisa iileya kunye kwaye kuthintele amalungu abandayo abuthathaka. Xa ugalela nzulu kakhulu, sebenzisa iishafti ezide eziguquguqukayo ukuze isidlidlizi sifike ezantsi ngaphandle kobunzima.
Kwenzeka ntoni xa ungcangcazela kakhulu okanye kancinci kakhulu?
Ukungcangcazela okuncinci kakhulu kushiya i-voids, i-honeycombing, kunye neendawo ezibuthathaka. Ezi zinto zinciphisa amandla kwaye zivumela amanzi ukuba angene, ebangela iintanda kamva. Ukungcangcazela kakhulu kubangela ukuhlukana, apho amatye anzima atshona kunye ne-samente i-sement iphakama, ishiya umxube ongalinganiyo. Oku kwenza ikhonkrithi ibe buthathaka kwezinye iindawo kwaye ibe brittle kwezinye. Ezona ziphumo zihle zivela ekulandeleni ubunzulu obuchanekileyo, izithuba, kunye nexesha lokuhlala le-vibrator esetyenziswayo.
Indlela yokukhetha i-vibrator yekhonkrithi?
Ukukhetha isixhobo esilungileyo sokungcangcazela kwekhonkrithi kuxhomekeke kuhlobo lweprojekthi, ubungakanani becandelo lekhonkrithi, kunye nomthombo wamandla okhoyo. Kukho iindidi ezininzi zeevibrators: zangaphakathi (untywiliselo), iivibrators zomphezulu, iivibrators zangaphandle, kunye ne table vibrators. Iivibrators zangaphakathi zezona zixhaphakileyo kwiindawo zokwakha kuba zinokufakwa ngokuthe ngqo kumxube omtsha. Iivibrators ezingaphezulu zisetyenziselwa amacwecwe amancinci, ngelixa iivibrators zangaphandle zincamathela kwi-formwork kwaye zihlala zisetyenziselwa iimveliso zangaphambili.
Cinga ngomthombo wamandla
Iimodeli ze-vibrator zekhonkrithi zombane zithandwa kwiiprojekthi zasezidolophini apho umbane ufikeleleka lula. Ziyasebenza, zithe cwaka, kwaye kulula ukuzisebenza. I-petroli okanye i-diesel vibrator zifaneleke ngakumbi kwiindawo ezikude ezingenamandla ombane. I-vibrators ye-Pneumatic isetyenziswe kwiimeko ezikhethekileyo apho kukho ukunikezelwa komoya. Uhlobo ngalunye luneenzuzo, ngoko kubalulekile ukufanisa umthombo wamandla kwiimeko zesayithi yeprojekthi.
Tshatisa ubungakanani bentloko nomsebenzi
Iintloko ezinkulu zevibrator zinamandla kwaye zinokudibanisa amacandelo ashinyeneyo ekhonkrithi ngokukhawuleza. Iintloko ezincinci zingcono kwizinto ezincinci kunye neendawo ezinokuqina okuxineneyo apho indawo iyancipha. I-shaft eguquguqukayo ivumela umqhubi ukuba afikelele nzulu kwiikholomu kunye neendonga. Ubude be-shaft kufuneka bukhethwe ngokuhambelana nobunzulu bokuthulula ukuphepha iingxaki zokuphatha ezingadingekile.
Jonga i-frequency kunye ne-amplitude
I-Vibrators isebenza ngokudibanisa i-frequency (indlela ekhawuleza ngayo ukungcangcazela) kunye ne-amplitude (indlela yomelele ngayo intshukumo). I-high-frequency, i-low-amplitude vibrators ilungile kumxube we-fluid kunye nee-aggregates ezincinci. I-low-frequency, high-amplitude vibrators ingcono kwimixube eqinile okanye i-aggregates enkulu. Ukukhetha ibhalansi echanekileyo kuthintela zombini ngaphantsi kwe-vibration kunye ne-over-vibration.
Ukuqina kunye nokugcinwa
Ivibrator elungileyo kufuneka yomelele, kube lula ukuyicoca, kwaye kukhuseleke ukuyigcina. Jonga izinto ezifana neebheringi ezitywiniweyo, iishafti ezomeleleyo, kunye nezikhuselo ezikhuselayo. Ababoneleli abathembekileyo babonelela ngamacandelo asecaleni kwaye banikezela ngenkonzo emva kokuthengisa. I-Ningbo ACE Machinery, umzekelo, ineqela elisemgangathweni kwaye inikezela ngoqeqesho lokusebenza ngokufanelekileyo. Oku kunciphisa ixesha lokuphumla kunye nokuqinisekisa ukuba isixhobo ngasinye sinikezela ubomi obude benkonzo.
Iindlela ezilungileyo zokungcangcazela ikhonkrithi
Phambi kokungcangcazela
Cwangcisa ipateni yokufaka kwangaphambili. Khangela ukuba intloko ye-vibrator kunye neshafti zikwimeko efanelekileyo. Qinisekisa ukuba iintambo zombane okanye iintambo zamafutha zikhuselekile. Beka abasebenzi ukuze bafikelele kuzo zonke iindawo ngaphandle koxinzelelo. Ukuba ukuqiniswa kuqinile, sebenzisa iintloko ezincinci ukuphepha umonakalo.
Ngexesha lokungcangcazela
Faka ivibrator ngokuthe nkqo, hayi kwi-engile. Musa ukuyirhuqa kumxube. Gcina izithuba zofakelo zingaguquguquki kwaye zisoloko zidibana kancinane iindawo. Bamba isidlidlizi ixesha elide ngokwaneleyo ukuze amaqamza abaleke, emva koko urhoxe kancinci. Gwema ukuchukumisa ifomwork ngokuthe ngqo, njengoko oku kunokonakalisa zombini isixhobo kunye nefom.
Emva kokungcangcazela
Emva kokuba ukungcangcazela kugqityiwe, vumela umphezulu wekhonkrithi ukuba uzinze. Musa ukongeza amanzi okanye uphinde usebenze umxube, njengoko oku kunciphisa isakhiwo. Khusela umphezulu wonyango olufanelekileyo. Ukuba kukho i-honeycombing okanye i-voids ibonakala, yilungise ngaphambi kokuba ibangele imiba yexesha elide.
Isishwankathelo
Ubunzulu bokungcangcazela okufanelekileyo kunye nezixhobo ezichanekileyo ziqinisekisa ukuba ikhonkrithi yomelele, igudile, kwaye ihlala ixesha elide.
