Umhlinzeki wemishini yokwakha wezixazululo zemishini yokwakha iminyaka engama-30.
Ukukhetha i-vibrator yekhonkrithi efanele kufana nokukhetha amabhuzu afanele endaweni yokwakha. Elikhulu kunazo zonke alilona eliwusizo kakhulu ngaso sonke isikhathi. Ikhanda le-poker elikhulu lingabonakala linamandla kukhathalogi, kodwa uma lingakwazi ukudlula ekuqiniseni okuqinile noma lifinyelele phansi kokuthululwa, ngeke lenze umsebenzi kahle. I-poker encane, ngakolunye uhlangothi, ingangena kalula ezindaweni ezincane, kodwa idinga izindawo zokufaka ezengeziwe kanye nesikhathi esiningi sokusebenza.
Lo mhlahlandlela wokuthenga i-concrete vibrator uchaza indlela yokukhetha imodeli efanele ngokombono wendawo yokusebenza osebenzayo. Esikhundleni sokubheka amandla enjini kuphela, abathengi kufanele baqhathanise usayizi we-poker, ubude bomgodi, umthombo wamandla, imvamisa yokudlidliza, isikhala sokufakwa kanye nezidingo zokulungisa. Kwabakhi benkontileka, abathengisi, izinkampani zokuqasha kanye namaqembu okuthenga, le ndlela isiza ukunciphisa ukuhluza uju, ukuthuthukisa ubuningi bekhonkrithi futhi igweme ukuthenga imishini ebukeka kahle ephepheni kodwa enenkinga kukhonkrithi yangempela.
Umshini wokudlidliza wekhonkrithi ususa umoya ovalelekile kukhonkrithi entsha. Uma ukhonkrithi uthelwa, amaphakethe omoya ahlala phakathi kwe-aggregate, i-cement paste kanye ne-reinforcement. Uma lawo maphakethe omoya ehlala ngaphakathi kwesakhiwo, umphumela ungaba ukutshala izinyosi, izindawo ezibuthakathaka kanye nokuphela kobuso obubi. I-vibrator yekhonkrithi ithumela ukudlidliza ngengxube, okuvumela amabhamuza omoya ukuba akhuphuke ngenkathi udaka lugeleza eduze kwetshe kanye ne-rebar.
I-vibrator kufanele icindezele ukhonkolo, ingawususi phezu kwefomu. Leli yiphutha elivamile endaweni. Uma umqhubi esebenzisa i-poker njengesipuni ebhodweni lesobho, ukhonkolo ungahlukanisa, futhi akekho ofuna isobho lekhonkolo elinamatshe phansi kanye ne-paste enamanzi phezulu. Ngokusho kuka Isiqondiso sesakhiwo sekhonkrithi seCaltrans , ukhonkolo kufanele udlidlize kuze kube yilapho udoti namanzi kugeleza phezulu, futhi ukudlidliza ngale kwalelo phuzu akudingeki noma akufiseleki.
Indlela ewusizo kakhulu yokukhetha i- concrete poker vibrator ukuqala ngesakhiwo. Bheka isikhala sokuqinisa, ukujula kokuthululwa kanye nesimo sefomu ngaphambi kokukhetha ikhanda le-poker. I-poker efanele ngokuvamile ikhanda elikhulu kunazo zonke elingadlula esiqiniselweni, lifinyelele phansi kwekhonkrithi bese lishukunyiswa liqonde phezulu ngaphandle kwamandla.
Lokhu kubalulekile ngoba ukufinyelela ngokuvamile kuyimingcele yangempela endaweni. Ekuqiniseni okuminyana, Ingxoxo ye-ASCC ngesiqondiso se-ACI 309R-05 ithi ukudlidliza kwangaphakathi kudinga ukugijima okuqondile okungenazithiyo okungenani okungu -4 × 6 in. (100 × 150 mm) , futhi isikhala esivundlile salezi zimbobo akufanele sidlule amasentimitha angu-24 (610 mm) noma izikhathi ezingu-1.5 kune-radius yethonya . Lokho kusho ukuthi i-poker enkulu ingcono kuphela uma isakhiwo siyinika indawo eyanele yokusebenza.
| Ububanzi bekhanda le-Vibrator | Irediyasi Yethonya | Isikhala Esiphezulu Sokufaka | Ukusetshenziswa Okufanelekile |
|---|---|---|---|
| 3/4 intshi. | 3 in. | 4.5 in. | Ukuqinisa okuqinile kakhulu noma umsebenzi wokulungisa omncane |
| 1-1/2 in. | 6 in. | 9 in. | Amakholomu, izindonga ezincane kanye ne-rebar ebanzi |
| 2 in. | 8 in. | 12 in. | Umsebenzi ojwayelekile wekhonkrithi eqinisiwe |
| 2-1/2 in. | 10 in. | 15 in. | Izinyawo, imishayo kanye nezingxenye eziphakathi nendawo |
| 3 in. | 12 in. | 18 in. | Vula izingxenye ezinesikhala esanele sokusebenza |
| 3-1/2 in. | 14 in. | 21 in. | Ukuthulula okukhulu okunezingcindezi ezincane |
Ithebula libonisa ukuthi kungani isikhala sokufaka kungafanele siqagelwe ngamehlo. Isibonelo, Idatha esekelwe ku-ACI efingqiwe yi-ASCC Ibala ikhanda lokudlidliza langaphakathi elingamasentimitha angu-2-1/2 elinobubanzi obungamasentimitha angu-10 kanye nesikhala esiphezulu sokufaka esingamasentimitha angu -15. Ikhanda elincane lisengasebenza kahle, kodwa umqhubi kumele alifake kaningi. Lokho akuyona inkinga uma iqembu lihlela lokho; kuba yinkinga kuphela lapho wonke umuntu elindele ukuthi i-poker encane imboze ukhonkolo njengelikhulu.
Ubude bomshafti wokudlidliza wekhonkrithi kufanele buhambisane nebanga lokusebenza langempela phakathi kweyunithi yamandla nendawo yokufaka. Umshafti omfushane kulula ukuwulawula kuma-slab, izisekelo ezincane kanye nomsebenzi wokulungisa. Umshafti omude oguquguqukayo uwusizo ezimweni ezijulile, ekuthululweni okukhulu nasezindaweni lapho injini noma injini ingenakuma eduze kokhonkrithi.
Amashafu amade angasiza ekufinyeleleni, kodwa ubude obengeziwe bunezela nomzamo wokudonsa nokuphatha. Umsebenzisi usadinga ukufaka i-poker ngokuqondile, ayihlise ngaphansi kokulawula bese eyihoxisa kancane kancane. I-NPCA, icaphuna isiqondiso se-Portland Cement Association , inikeza umthetho osebenzayo owusizo: ngemva kokuba i-vibrator izike ngaphansi kwesisindo sayo, yikhiphe cishe ngemizuzwana emi-3 ngonyawo oluqondile (300 mm) . Lokhu kunikeza isikhathi sikakhonkolo sokuvala ngemuva kwe-poker esikhundleni sokushiya umgodi obukeka sengathi umshini usayine igama lawo ekuthululweni.
I -vibrator yekhonkrithi kagesi iyisinqumo esinengqondo uma kukhona amandla azinzile atholakalayo. Ifanela izindawo zokwakha, umsebenzi wangaphakathi, izindawo ezilungiselelwe kusengaphambili kanye namaphrojekthi lapho kukhethwa khona ukukhishwa komoya okuphansi. Abathengi kufanele bahlole i-voltage, ubude bekhebula, ukuvikelwa kweswishi kanye nokuhambisana kwamandla endawo ngaphambi koku-oda.
Isidlidlizi sekhonkrithi kaphethiloli singcono kakhulu emsebenzini wangaphandle, emisebenzini yasemgwaqweni, ezisekelweni ezikude nasezindaweni lapho ugesi ungathembeki khona. Sinikeza inkululeko eyengeziwe yokuhamba, kodwa abathengi kudingeka bacabange ngophethiloli, isevisi yenjini, umsindo kanye nezingxenye ezisele. Kwabakhi abadlidliza ikhonkrithi nsuku zonke, uhlelo olusebenzisa imvamisa ephezulu lunganikeza umkhiqizo ozinzile kakhulu ngezikhathi zokusebenza ezinde.
Ngokwesibonelo, Ikhathalogi yokuhlanganiswa kwekhonkrithi ye-OLI Ibala ama-vibrators kagesi angaphakathi anemvamisa ephezulu anokufakwa okungu -42V, kwesigaba sesithathu, okungu-200Hz kanye nemvamisa ejwayelekile engu- 12,000 vpm . Ikhathalogi efanayo iphawula ukuthi amanye amamodeli e-converter angaguqula ukufakwa kwesigaba esisodwa okungu -230V noma okungu-110V, okungu-50/60Hz kube umphumela wemvamisa ephezulu odingekayo kulowo msebenzi wokudlidliza.
Kwabaningi abathulula okuvamile, imizuzwana emi-5-15 ngephuzu lokufaka liyibanga eliwusizo lokuqala. I-NPCA ibika ukuthi isiqondiso se-Portland Cement Association inikeza isikhathi sokufaka semizuzwana emi-5 kuya kweyi-15 njengoba kuvame ukwanele ukuhlanganiswa okwanele, yize isikhathi esiqondile sincike kusayizi wesidlidlizi, ukusebenza kahle kokhonkolo kanye nokujula kwamalungu.
Umqhubi akufanele asebenze ngewashi lokumisa kuphela. Ikhonkrithi entsha inikeza izimpawu uma isinele. Amabhamuza omoya amakhulu ayayeka ukuphakama, ubuso buyahlala, umsindo we-vibrator uyashintsha futhi kuvela ukukhanya okuncane kwe-mortar. Uma i-poker isusiwe futhi imbobo ingavaleki, ikhonkrithi ingadinga ukufakwa kabusha okufushane eduze. Uma ubuso buba namanzi noma i-aggregate iqala ukuhlala, i-vibrator ihlale isikhathi eside kakhulu. Njengezinto eziningi endaweni, isikhathi esihle asikona ukushesha; simayelana nokwazi ukuthi kufanele ume nini.
Iphutha lokuqala ukuthenga ngobubanzi be-poker kuphela. Umthengi kufanele ahlole njalo ukuqina kwesikhala kanye nesikhala sokufakwa kuqala. Iphutha lesibili ukukhetha umgodi omude kunayo yonke iphrojekthi. Uma umsebenzi omningi ungajulile futhi useduze neyunithi yamandla, umgodi omude ungenza umqhubi akhathale ngokushesha. Iphutha lesithathu ukuqhathanisa amandla enjini kuphela ngenkathi ungazinaki imvamisa, ububanzi be-poker kanye ne-radius yethonya.
Kubathengisi nezinkampani zokuqasha, imodeli eyodwa ayivami ukumboza wonke amakhasimende kahle. Uhla oluwusizo lungafaka amakhanda amancane e-poker okuqinisa kakhulu, amakhanda aphakathi ezinsimbi nezisekelo, kanye namakhanda amakhulu okuvula imishini. Lokhu kwenza imishini ibe lula ukuyifanisa nemisebenzi yangempela futhi kunciphisa amathuba okuthi ikhasimende lisole umshini lapho inkinga yangempela yayiwukukhetha okubi.

Ngemva kokusetshenziswa ngakunye, hlanza ikhanda le-poker, i-shaft, i-hose kanye ne-coupling ngaphambi kokuba i-concrete residue iqine. I-flexible shaft, ama-bearings, ama-seal, i-switch kanye nokuxhumeka kwamandla kufanele kuhlolwe njalo ngoba amathuluzi okudlidliza ekhonkrithi asebenza ezimweni ezimanzi, ezirhabaxa nezinomthwalo omningi.
Ukuze uthole ukuxazulula inkinga elula yokudlidliza ngekhonkrithi , hlukanisa inkinga ibe izingxenye ezimbili. Uma injini noma injini ingaqali, hlola ukunikezwa kwamandla, uphethiloli, izinga likawoyela, iswishi, i-spark plug, ikhebula kanye nokuvikelwa kokulayisha ngokweqile. Uma iyunithi yokushayela isebenza kodwa i-poker idlidliza kancane, hlola uxhumano lwe-shaft, ukuguguleka kwe-shaft okuguquguqukayo, isimo samabhere, umonakalo wekhanda le-poker kanye nokugcotshwa. Lokhu ku-oda konga isikhathi ngoba kugwema ukufaka ezinye izingxenye ezingahleliwe ngenkathi abasebenzi bebuka ukhonkrithi omusha uba musha kancane kancane.
Khetha ikhanda le-poker elikhulu kunawo wonke elingadlula esisekelweni, lifinyelele phansi kwendawo bese lihamba liqonde phezulu ngaphandle kwamandla. Esisekelweni esiqinile, hlola kuqala izikhala zokufinyelela; Isiqondiso esisekelwe ku-ACI se-ASCC kubhekisela okungenani ekugijimeni okuqondile okungavimbeli okungu- 4 × 6 intshi (100 × 150 mm) kokunyakaza kwangaphakathi.
Isikhala sokufaka kufanele silandele ububanzi bethonya le-poker. Isibonelo, Idatha esekelwe ku-ACI efingqiwe yi-ASCC inikeza ikhanda elingu -2-1/2 intshi ububanzi obuyi- 10 intshi kanye nesikhala esiphezulu sokufaka esingama- intshi angu-15.
Uma uthulula izinto eziningi ezivamile, sebenzisa imizuzwana emi-5-15 endaweni ngayinye yokufaka njengebanga lokuqala, bese wahlulela ngamabhamuza omoya, ukukhanya kwendawo, ukuqina kwekhonkrithi kanye nomsindo wokudlidliza. Leli banga lesikhathi elisebenzayo lisekelwa futhi yi Ingxoxo ye-NPCA mayelana nomkhuba ofanele wokudlidliza .
I-vibrator yekhonkrithi efanele ikhethwa ngokusebenza emuva emsebenzini. Hlola isikhala sokuqinisa kuqala, bese ukhetha ububanzi be-poker, ubude bomgodi, umthombo wamandla, imvamisa yokudlidliza kanye nesikhala sokufaka. I -vibrator yekhonkrithi yekhonkrithi ehambisana kahle isiza ukususa umoya ovalelekile, ukunciphisa ukuhluma kwezinyosi futhi inikeze osonkontileka ikhwalithi yekhonkrithi ebikezelwayo.
Kubathengi be-B2B, ukuthenga okuhlakaniphile kakhulu akuyona imodeli eshibhile noma ikhanda le-poker elikhulu kunawo wonke. Uhla lwemodeli oluhambisana namaphrojekthi amakhasimende akho aphathayo ngempela. Uma umsebenzi wakho uhlanganisa ama-slabs, amakholomu, izisekelo kanye nezindonga eziqiniswe kakhulu, usayizi we-poker kanye nokwakheka komgodi okungaphezu kowodwa ngokuvamile kuzokhonza imikhumbi kangcono kunomshini owodwa "ofanela wonke umuntu".
