Lub npog qhov dej tseem hu ua "ditch cover ", "manhole cover", "ditch cover", "manhole cover was originally made of cement, thiab nws tau yooj yim puas nyob rau hauv ib txwm siv ntawm nruab nrab kwj dej. Tom qab lub ditch yog welded los ntawm steel grating, uas yog lub teeb thiab lub teeb yuag, cov khoom yog ntsia rau hauv tib txoj kev, qhov cuam tshuam tsis kam yog yooj yim, kev tsim kho zoo nkauj thiab kev siv yog loj, thiab qhov loj cheeb tsam tus nqi tom qab lub tshav kub npog. kev tsim kho. Los ntawm kev sib txuas lossis siv cov khoom sib txuas los txuas rau lub rooj tsav xwm tiv thaiv tub sab, thiab lwm yam, lub rooj tsav xwm tiv thaiv tub sab thiab lwm yam haujlwm siv hauv steel lattice npog thiab qee qhov chaw nyob hauv high-end tau dav siv. Lub npog npog npog tuaj yeem siv dav hauv ntau qhov chaw xws li txoj kev hauv nroog, cov chaw lag luam, cov tsev nyob, tsev kawm ntawv, cov neeg saib xyuas tsev thiab lwm yam. Nws tuaj yeem nruab nrog lub phaj txav txav thiab sib dhos phaj tshuab lossis cov cuab yeej tiv thaiv tub sab raws li xav tau.
1. Cov kev taw qhia ntawm lub tiaj tus hlau ntawm lub ditch cover yog lub load-bearing (txhawb) kev taw qhia, thiab qhov ntev L ntawm lub tiaj tus steel yog txiav txim siab raws li qhov dav ntawm qhov ditch (zoo);
2. Raws li qhov ntev ntawm qhov zawj (zoo), coj tus qauv board dav ntawm 995mm uas ua tau raws li cov txheej txheem ua, thiab tawm qhov sib txawv ntawm 5mm ntawm cov laug cam;
3. Qhov seem ntawm qhov trench (zoo) ntev tsawg dua 1 meter yog qhov loj ntawm lub module;
4. Xaiv hom steel grating raws li qhov dav ntawm qhov ditch (zoo) thiab cov kev cai bearing.
5. Nws raug pom zoo kom xaiv cov qauv me me ditch npog rau kev tsim thiab kev tsim kho, thiab lwm yam kev qhia tshwj xeeb tuaj yeem hloov kho.
Nta ntawmgutter cover:
1. Kub-dip galvanized nto kho: Nws muaj zog xeb kuj.
2. Kev tsim kho hauv tsev zoo tshaj plaws los tiv thaiv npog: lub hau npog ua los ntawm cov hlau grating yog txuas nrog lub thav duab nrog cov hinges, uas yog tiv thaiv tub sab nyiag, muaj kev nyab xeeb thiab yooj yim qhib.
3. Cov khoom lag luam muaj qhov zoo nkauj zoo nkauj: cov kab yooj yim, cov duab nyiaj, cov tswv yim niaj hnub
4. Qhov loj mesh muaj cov kua dej zoo tshaj plaws: qhov dej xau yog 83.3%, uas yog ntau tshaj ob npaug ntawm cov hlau cam khwb cia.
5. Cov khoom siv tau txais kev cawmdim thiab kev nqis peev tau txais kev cawmdim: thaum siv qhov loj thiab hnyav hnyav, tus nqi qis dua li cov hlau cam khwb cia; thiab tus nqi ntawm kev hloov cov cam khwb cia hlau npog vim yog tub sab lossis crushing tuaj yeem txuag tau.
6. Kev siv cov pa roj carbon steel muaj zog ua rau cov hlau grating muaj lub zog siab: lub zog thiab lub zog muaj zog ntau dua li cov hlau cam khwb cia, thiab tuaj yeem siv rau hauv qhov chaw loj thiab hnyav hnyav xws li docks thiab tshav dav hlau.
7. Muaj ntau ntau yam ntawm cov khoom: ua tau raws li qhov xav tau ntawm qhov sib txawv ntawm ib puag ncig, loads, spans thiab cov duab, thiab tuaj yeem muab qhov ntau thiab tsawg thiab cov duab raws li cov neeg siv khoom.
