Cov txheej txheem mechanics sib txawv ntawm puag ncig thiab square manhole npog. Round manhole npog muaj ib qho zoo kawg nkaus symmetrical tsim, uas ua rau cov teeb meem kev ntxhov siab thiab tsis muaj teeb meem kev ntxhov siab. Lawv lub zog compressive yog 20%-30% siab dua li ntawm cov square manhole npog, thiab lawv muaj peev xwm tiv taus ntau dua rau kev deformation thiab tawg nyob rau hauv kev cuam tshuam. Square manhole npog, ntawm qhov tod tes, muaj qhov kev ntxhov siab hauv qhov tsis xws luag ntawm lawv plaub lub ces kaum, ua rau lawv ua rau cov hlau qaug zog thiab kev puas tsuaj hauv cheeb tsam nyob rau hauv ntev - lub sij hawm hnyav. Nyob rau hauv cov ntsiab lus, puag ncig manhole npog yog superior rau square manhole npog nyob rau hauv cov nqe lus ntawm load- bearing muaj peev xwm, durability, thiab structural stability, ua rau lawv lub zoo tagnrho xaiv rau high-siv kev khiav hauj lwm ib puag ncig.
Kev nyab xeeb yog qhov tseem ceeb tshaj plaws rau kev xaiv npog manhole, thiab cov npog puag ncig muaj kev nyab xeeb dua li cov square. Round npog muaj ib txoj kab uas hla tsis sib xws uas tiv thaiv plam mus rau hauv qhov dej thiab cov npoo du uas tsis txhob mus ncig thiab cov log tsheb scuffs. Square npog, txawm li cas los xij, pheej hmoo plam ntawm lawv cov kab pheeb ces kaum ntev dua thaum qaij, thiab lawv cov npoo ntse ua rau muaj kev phom sij rau cov neeg taug kev thiab cov log tsheb. Yog li ntawd, cov npog puag ncig yog qhov kev xaiv tsis muaj teeb meem rau pej xeem kev nyab xeeb.
Round manhole npog muaj qhov zoo sib xws hauv kev txhim kho kev ua haujlwm thiab kev tswj xyuas tus nqi. Lawv tsis yog -kev taw qhia tsim zam zam kev sib raug zoo thaum lub sij hawm haum, thiab rollable xwm enables yooj yim ib leeg -tus neeg tuav, zoo heev txo zog siv zog. Lawv cov qauv muaj zog kuj tseem txuas ntxiv txij nkawm ncua sijhawm, txo cov kev pabcuam cuam tshuam tsawg. Hauv qhov sib piv, square manhole npog yuav tsum nruj kev teeb tsa: plaub lub ces kaum yuav tsum ua tib zoo ua kom tsis txhob muaj kev sib tsoo lossis qhov khoob. Unrollable, lawv lub zog xav tau pab pawg, siv sijhawm ntau thiab ua haujlwm. Cov fab tsis zoo kuj ua rau muaj qhov tsis ua haujlwm ntau dua thiab hloov pauv tsis tu ncua, ua rau lub sijhawm ntev - cov nqi tu hauv nroog.
Nyob rau hauv cov nqe lus ntawm kev siv cov khoom siv thiab kev lag luam, round manhole npog excel ntawm tus nqi txo thiab kev txhim kho kev ua haujlwm. Lawv cov geometry txo cov khoom siv kom sib npaug ntawm - thaj tsam manhole, kom ntseeg tau tias kev siv tau zoo. Ntxiv mus, cov txheej txheem tsim khoom yooj yim thiab kev tsim pwm pab txo cov nqi tsev ntau.
Hloov pauv, square manhole npog qhov kev thov nce qhov ntev thiab cov khoom siv nkag mus kom ua tiav cov txiaj ntsig zoo ib yam, ua rau cov peev txheej pov tseg. Lawv cov pwm complex thiab nruj ntau lawm yuav tsum tau txhais ua ntau dua raug nqi piv nrog round counterparts.Yog li, round manhole npog ntaus ib tug zoo tshuav nyiaj li cas ntawm cov qauv lub zog thiab nyiaj txiag kev pab cuam.
Raws li lawv qhov kev ua tau zoo sib txawv, ob hom manhole npog tau qhia meej meej cov ntawv thov. Round manhole npog, nrog rau lawv cov load siab -cov kabmob muaj peev xwm thiab kev nyab xeeb, yog qhov kev xaiv zoo tshaj plaws rau hauv nroog txoj kev loj, txoj kev loj, thiab cov squares uas muaj neeg coob. Lawv kuj tau siv dav rau cov kav dej thiab cov kav dej vim lawv qhov yooj yim ntawm kev saib xyuas. Square manhole npog, ntawm qhov tod tes, feem ntau yog siv nyob rau hauv chaw nres tsheb lossis txoj kev sab hauv hauv thaj chaw nyob uas cov tsheb thauj khoom qis dua. Hauv cov hlua ntsuab thiab cov nyom, lawv cov duab sib xyaw yooj yim dua nrog cov pob zeb square paving, tsim kom pom kev sib haum xeeb thiab zoo nkauj zoo nkauj. Tsis tas li ntawd, rau cov cuab yeej tshwj xeeb tu cov qhov dej uas xav tau qhov qhib loj, lub square tsim zoo sib xws rau cov txheej txheem sab hauv.
