Ukudityaniswa kwecandelo kunye nokudityaniswa kombhobho wekholvethi exonxiweyo

Abadityanisiweyo umbhobho wekholvethi exonxiweyoyenziwe ngamaqhekeza amaninzi eepleyiti ezigxothiweyo ezigxininiswe ngeebholiti kunye namantongomane, kunye namacwecwe amancinci, ubunzima bokukhanya, kulula ukuthuthwa kunye nokugcinwa, inkqubo elula yokwakha, kulula ukufakwa kwisiza, ukusombulula ingxaki yokutshatyalaliswa kweebhulorho kunye ne-culvert yombhobho. izakhiwo kwiindawo ezibandayo, kunye nokuhlanganisa ngokukhawuleza, ixesha elifutshane lokwakha kunye nezinye iingenelo.

Indibano yecandelo lombhobho kunye nokudityaniswa kwe-corrugated edibeneyoumbhobho weculvert
1, Ukulungiswa kolwakhiwo lwangaphambili: jonga ukucaba, ukuphakama komzantsi wombhobho we-culvert kunye nokusekwa kwesiseko esibonwe ngaphambili, misela indawo, i-axis yombindi kunye ne-midpoint yombhobho we-culvert.
2 、 Ukudibanisa ipleyiti esezantsi: thatha i-axis yeziko kunye ne-midpoint njengesalathisi, ipleyiti yokuqala yamalahle ibekwe, kwaye inabela kumacala omabini oku njengendawo yokuqala de iziphelo ezimbini zokungenisa nokuthumela ngaphandle kombhobho we-culvert; ipleyiti yesibini ifakwe phezulu kweyokuqala (ubude be-lap yi-50mm), kwaye ihambelana nemingxuma yokudibanisa. I-bolt ifakwe kwi-screw hole ukusuka ngaphakathi ukuya ngaphandle, icala elichasene neseti ye-washers nut, qinisa kwangaphambili i-nut nge-wrench socket.
I-3 ukudibanisa i-seams edibeneyo ngokungahambi kakuhle, ukudibanisa imingxuma kanye emva kokuba iibholiti zifakwe ngaphakathi ngaphakathi kwimingxuma ye-screw, qinisa kwangaphambili i-nut kunye ne-socket wrench.
I-4, ubude bemitha nganye buhlanganiswe emva kokubunjwa, ukumisela ubume becandelo elinqamlezileyo, ukuhlangabezana nemigangatho kwaye emva koko uqhubeke nokuhlanganisana, ngaphantsi komgangatho kufuneka ulungiswe ngexesha elifanelekileyo. Indibano ye-Circumferential kwindandatho xa ikhonkco ihlangene, ukuzimisela kwemilo ye-cross-sectional, usebenzisa i-position tie rod esisigxina, ukulungelelanisa iibholithi zangaphambili, ukudibanisa umbhobho we-corrugated.

5, Emva kokuba konke ukuhlanganiswa kombhobho we-culvert kugqityiwe, sebenzisa i-fixed-torque wrench yomphunga ukuqinisa zonke iibholithi ngokwetorque ye-135.6 ~ 203.4Nm, ngokulandelelana, ukuze ungaphoswa, kwaye iibholiti ezisezantsi ziphawulwe ngobomvu. ipeyinti emva kokuqina. Zonke iibholiti (kubandakanywa i-longitudinal kunye ne-circumferential joints) kufuneka ziqiniswe ngaphambi kokuzaliswa ngasemva ukuze kuqinisekiswe ukuba iindawo ezidibeneyo ze-corrugation ziqiniswe ngokuqinileyo kunye.

6. Ukuqinisekisa ukuba ixabiso elifunekayo lexesha le-bolt torque liphunyeziwe, khetha ngokungakhethiyo i-2% yeebholiti kwii-longitudinal joints kwisakhiwo ngaphambi kokubuyisela umva, kwaye wenze uvavanyo lwesampulu kunye ne-torque wrench eqhubekayo. Ukuba naluphi na uluhlu lwexabiso le-bolt torque alufikeleli kwixabiso elifunekayo, ngoko ke i-5% yazo zonke iibholiti kwi-longitudinal kunye ne-circumferential joints kufuneka ithathwe isampuli. Ukuba zonke ezi mvavanyo zesampulu zingentla zihlangabezana neemfuno, ukufakela kuthathwa njengokwanelisayo. Ngaphandle koko, kufuneka ihlolwe kwakhona ukuze kuqinisekiswe ukuba ixabiso letorque elilinganisiweyo liyahlangabezana neemfuno.
7 imingxunya yokuthintela ukuphuma kwamanzi kwindawo edibeneyo yepleyiti.
I-8, emva kokuba ukufakwa kugqityiwe, kumbhobho ngaphakathi nangaphandle kwe-uniform brush asphalt, i-asphalt ingaba i-asphalt eshushu okanye i-emulsified asphalt, i-asphalt layer kufuneka ibe ngaphantsi kobunzima obupheleleyo be-1mm.
