Isembozo se-composite Manhole Cover luhlobo lwekhava ye-manhole yokuhlola, futhi izimfanelo zalo ziyachazwa: Isembozo se-Manhole sokuhlola sihlanganiswa yinqubo ethile esetshenziswa nge-polymer njenge-matrix ebonakalayo, engeza izinto zokuqinisa, ama-filler, njll.
Eqinisweni, isembozo se-resin manhole (esibizwa nangokuthi i-polymer glass fiber eqiniswe ikhava ye-manhole yepulasitiki / i-composite yezinto ze-manhole manhole) Ikhava ye-manhole esebenzisa isembozo se-manhole esisebenzisa izinto zokuqinisa kanye ne-resin ye-matrix. Siqukethe i-polyester resin engafakwanga, ama-fillers, abaqandayo, izithasiselo eziphansi ze-shrinkage, ama-ejenti wokubumba amafilimu, ama-ejenti wokubumba amafilimu, imibala kanye nohlobo olusha lomkhiqizo ophoqelelwe olubunjiwe ekushiseni okuphezulu.
Phakathi kwezinto ezingezwe, izinto eziqinisiwe ze-fiber (indwangu yengilazi, itheyipu, uzizwe, intambo, njll.) Yizona eziphambili, ezibonakala ngamandla amancane, ama-modulus amakhulu athile. Isibonelo, impahla eyinhlanganisela ye-carbon fiber kanye ne-epoxy resin, amandla ayo athile kanye nama-modulus athile anezinkinga, ukumelana nokushisa, ukumelana nokudla, ukuncishiswa komsindo, ukuncipha kukagesi nezinye izakhiwo. Inhlanganisela ye-graphite fiber kanye ne-resin ingathola impahla enobuhle bokunwebeka cishe okulingana no-zero. Enye into yezinto eziqinisiwe ze-fiber ansotropy, ngakho-ke ukuhlelwa kwemicu kungaklanywa ngokuya ngezidingo zamandla ezingxenye ezahlukahlukene zomkhiqizo. Ama-aluminium matrix ama-composites aqiniswa yi-carbon fibers kanye nemicu ye-silicon carbide kusengagcina amandla anele kanye ne-modulus ngo-500 ° C.
Isembozo se-composite manhole singahlukaniswa nge-BMC kanye ne-SMC ngokuya ngesidingo semakethe, izinqubo ezahlukahlukene zokukhiqiza kanye nezinto zokwakha:
Izinto ze-BMC (DMC) ziyizinhlanganisela eziningi zokubumba. Imvamisa ibizwa ngokuthi yi-polyeturated polyester bulk compound compail eChina. Izinto eziphambili ezingavuthiwe yinhlama - efana ne-prepreg exutshwe ngokugcwele yi-GF (i-fiber eqoshiwe), phezulu (i-resin engalawulwa), i-MD (Filler) nezinye izithasiselo ezahlukahlukene. Izinto ze-DMC zisetshenziswe okokuqala entshonalanga neJalimane kanye ne-United Kingdom ngawo-1960, bese zithuthukiswa e-United States naseJapan ngeminyaka yo-1970 naku-1980s, ngokulandelana. Ngoba i-BMC inqwaba yokubumba yokubumba inezakhiwo ezinhle kakhulu zikagesi, izakhiwo zemishini, ukumelana nokushisa, ukumelana nokuqina kwamakhemikhali, futhi kuvumelana nezidingo ezahlukahlukene zemikhiqizo, futhi kusetshenziswa kalula imikhiqizo yokwakha kanye neminye imikhakha.
Ama-Composites we-SMC angamaphepha ahlanganisiwe. Izinto zokusetshenziswa eziphambili ezilukhuni zihlanganiswa ze-GF (i-yarn ekhethekile), phezulu (i-resin engalawulwa), isengezo esiphansi se-shrinkage, i-MD (Filler) nama-Auxiliaries ahlukahlukene. Kuvele okokuqala eYurophu ekuqaleni kweminyaka yo-1960, kwathi cishe ngo-1965, i-United States neJapan bathuthukisa ngale ndlela lobuciko. Ngasekupheleni kwawo-1980s, izwe lami lathula imigqa yokukhiqiza ye-SMC yakwamanye amazwe kanye nezinqubo zokukhiqiza. Izinto ezihlanganisiwe ze-SMC nemikhiqizo yazo ebunjiwe ye-SMC inezindawo ezinhle kakhulu zokufakwa kukagesi, izakhiwo zemishini, ukuqina okushisayo, nokuphikiswa kokugqwala kwamakhemikhali. Ngakho-ke, uhla lwezinhlobo zemikhiqizo ye-SMC luvame kakhulu. Umkhuba wentuthuko wamanje ukufaka izinto ze-BMC nge-SMC Composites.
Manje ukusetshenziswa kwesembozo sethu se-Resin Manhole kudlala indima enkulu empilweni yethu, futhi i-resin manhole isembozo sivelele ngenxa yokuzihlanza.
Ukusetshenziswa kwe-resin manhole izembozo emgwaqweni kunezimpawu zokufakelwa, akukho msindo, akukho inani lokuphinda usebenzise kabusha kanye ne-anti-noveft yemvelo. Akunakubekelwa indawo ye-caston manhole isembozo.
Isembozo se-Resin Manhole senziwa inqubo eyingqayizivele yokubumba, okwenza ukuthi idolobha libukeke libe lisha. Impilo yenkonzo ngokuyisisekelo iminyaka engama-20-50. I-resin composite manhole ikhava eyenziwe ngokubumba okuphezulu kokushisa inezinzuzo zesisindo esikhanyayo namandla aphezulu, ukumelana kahle nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala kanye nokulimala kokulimala. Inezinzuzo zokubumba okulula, umsindo ophansi wokugaya, ukumelana kahle kwamakhemikhali amakhemikhali, ukumelana okuhle kwe-acid kanye ne-alkali nokuphikiswa okuhle, futhi ukungcola emanzi angcolile kuyancishiswa.
Manje emakethe, izembozo ze-manhole ezikhiqizwa ngabakhiqizi abahlukahlukene be-manhole bemboleko zenziwe ngezinto ezahlukahlukene, kepha izici eziningana ziyafana:
1. Ukusebenza okunamandla okulwa-ukwebiwa Ukuqiniswa akulula kangako.
2. Ukuphila Kwesevisi: Ngokusebenzisa i-resin yokusebenza okuphezulu, i-fiber ye-glass kanye nefomula ekhethekile yenqubo yokukhiqiza, ukungena kwefomula yenqubo yenhlanganisela kahle embozweni yengilazi kuthuthukiswa kakhulu, ukuze izinto zibe zonakaliswa ngaphansi kwesenzo somthwalo we-cyclic. Umonakalo wangaphakathi wenzeka, ngaleyo ndlela uqinisekise impilo yenkonzo yomkhiqizo kanye nezinzuzo ezifanayo zamanye ama-resin composite manhole izembozo ze-manhole, eqeda ngempumelelo ukungathandeki kokunamathelisa.
I-3. Ukumelana okushisa okuphezulu / okuphansi okuphansi, ukusebenza okuhle kokufakelwa kanye nokumelana okuqinile kokugqwala: umkhiqizo ulwa nokugqwala, okungewona ubuthi futhi awunangozi. Azikho izengezo zensimbi. Ingasetshenziswa ezindaweni eziyinkimbinkimbi futhi eziguqukayo, ezinokhahlo nezidingayo. Izembozo zeManhole ezikhiqizwe ngabakhiqizi be-bester composite manhole Cover Caving Izikhungo Zokuhlola Okugunyaziwe, futhi babe nokuphikiswa okusobala kwe-acid kanye ne-alkali, ukumelana nokukhulisa kanye nezinye izinkomba eziningi ezihlangabezana namazinga wekhwalithi yomkhiqizo.
I-4. Kuhle futhi okusebenzayo, ibanga eliphakeme: ngokuya ngezidingo zamakhasimende aphezulu, singenza uphawu olunzima kanye nemibala ehlukahlukene ebusweni bomugqa ofanayo we-manhole amboza umuntu uqobo, ukuze umbala ugqamile futhi kucacile. Ngokwezidingo zamakhasimende, zingenziwa ekubonisweni kwamatshe ahlukahlukene okulingisa nemibala efana nemizana ehlukahlukene yamatshe.
I-5
I-6. Ukuvikelwa kwezemvelo, okungapheli, umsindo ophansi: Isembozo seManhole ngeke sishelele ngemuva kokuthi imoto igingqe, futhi ngeke kube nomsindo wendlebe nokungcola okuhlukile.
Lapho ufaka ikhava ye-manhole ye-composite, landela lezi zinyathelo ezine:
1. Ngaphambi kokufakwa, isisekelo sekhava yeManhole kufanele sihlanzeke futhi siqine, futhi ububanzi obungaphakathi, ubude nobubanzi kufanele bunqunywe ngokuya ngosayizi wesembozo se-manhole.
2. Lapho ufaka isembozo se-manhole se-composite emgwaqweni kasimende, unake i-Wellhead Masonry kufanele uthululwe ngokhonkolo, futhi indandatho yokuvikelwa kokhonkolo kufanele isungulwe ku-perifery ukuze ilungiswe isikhathi esiyizinsuku eziyi-10.
3. Lapho ufaka i-composite manhole emboza epakini le-asphalt, kufanele kubhekwe ukugwema imishini yokwakha edonsa ngokuqondile ikhava yeManhole kanye nesihlalo esihle ukugwema ukulimala.
4. Ukuze ulondoloze ubuhle besembozo seManhole kanye nokubhala ngesandla okucacile nephethini, qaphela ukuthi ungabi yi-manhole ikhava lapho uthela i-asphalt kanye nosimende endaweni yomgwaqo.
Indlela yokuthuthukisa:
. Ingathwala izimoto ezingaphezu kwama-40 zezimoto.
. Ingasetshenziswa ngezikhathi ezinezidingo eziphakeme zobuchwepheshe zesembozo se-manhole.
(3) Inzuzo yayo evelele ukuthi ayisebenzisi ukuqiniswa kwensimbi yensimbi, kepha iyaqiniswa nge-fiber fiber composite, okungokwemikhiqizo yohlobo lwe-GRC. Ngakho-ke, inenzuzo yokungathinteki lapho intengo yensimbi iyaqhubeka nokuvuka. Ngoba ayiqukethe insimbi encane, i-anti-ukweba ngokwengeziwe kunokuba itshe leplastiki ne-fiber concrete manhole emboza.
. Uma kukhiqizwa ngamashifu amathathu, kungadilizwa kathathu emahoreni angama-24. Yize inani lesikhunta lingaphezu kwalolo lwamatshe epulasitiki, kungu-1/6 kuphela wekhava ye-manhole yensimbi. Kunganciphisa futhi ukutshalwa kwezimali okubumba. Ngokuphuma konyaka kwama-10,000 amasethi wesembozo se-manhole, kudingeka amasethi ayi-10 kuphela ezikhuli.
