Ukuhlanganiswa kwengxenye nokuxhunywa kwepayipi likathayela likathayela

Ababuthene ipayipi likathayelayenziwe ngezingcezu eziningana zamapuleti kathayela ahlanganiswe nama-bolts namantongomane, anamapuleti amancane, isisindo esincane, kulula ukuthuthwa futhi agcinwe, inqubo yokwakha elula, ukufakwa kalula esizeni, ukuxazulula inkinga yokubhujiswa kwamabhuloho nezakhiwo zamapayipi e-culvert ezindaweni ezibandayo, ngokuhlangana okusheshayo, isikhathi esifushane sokwakha kanye nezinye izinzuzo.

Ukuhlanganiswa kwesigaba samapayipi kanye nokuxhumeka kwamathayela ahlanganisiweipayipi le-culvert
1, Ukulungiselela ukwakhiwa kwangaphambili: hlola ukucaba, ukuphakama kwepayipi le-culvert kanye nokumiswa kwe-arch ebonwe ngaphambili, thola indawo, i-axis ephakathi nendawo yepayipi le-culvert.
2, Ukuhlanganisa ipuleti elingezansi: thatha i-axis ephakathi nendawo njengereferensi, ipuleti likathayela lokuqala libekwe, futhi lidlulele nhlangothi zombili ngalokhu njengendawo yokuqala kuze kube semikhawulweni emibili yokungenisa nokuthekelisa kwepayipi le-culvert; ipuleti yesibili ihlanganiswe phezulu kweyokuqala (ubude bethanga bungama-50mm), futhi buqondaniswe nezimbobo zokuxhuma. I-bolt ifakwe emgodini wesikulufa kusukela ngaphakathi kuya ngaphandle, ohlangothini oluphambene nesethi yama-washers nut, qinisa kuqala inati nge-wrench yesokhethi.
3, Ukuhlanganisa indandatho kusuka phansi kuya phezulu ngokushintshana: ingxenye ethangeni yepuleti elingaphezulu elimboze ipuleti elingezansi, ukuxhumana okujikelezayo kusetshenziswa okunyathelayo, okungukuthi, amabhodi amabili angaphezulu axhuma ama-seam astakiwe kanye namabhodi amabili alandelayo okungahambi kahle komthungo, axhuma ukungahambi kahle kwemithungo estakiwe, axhuma izimbobo ezisuka ngaphakathi kwesokudla ngemuva kokufaka izimbobo. qinisa kuqala inati ngesikrufu sesokhethi.
I-4, ubude bemitha ngayinye obuhlangene ngemva kokubunjwa, ukucacisa ukuma kwe-cross-section, ukuhlangabezana nezindinganiso bese uqhubeka nokuhlangana, ngaphansi kwezinga kufanele kulungiswe ngesikhathi esifanele. Ukuhlanganiswa kokujikeleza kwendandatho lapho indandatho ihlangene, ukunqunywa kokuma kwesigaba esiphambanayo, kusetshenziswa induku yokubeka uthayi engashintshi, lungisa amabhawodi angaphambi kokuqina, ukuhlanganisa ipayipi likathayela.

5, Ngemuva kokuthi konke ukuhlanganisa ipayipi le-culvert sekuqediwe, sebenzisa i-fixed-torque steam wrench ukuze uqinise wonke amabhawodi ngokwetorque engu-135.6 ~ 203.4Nm, ngokulandelana, ukuze angaphuthelwa, futhi amabhawodi aphansi amakwe ngopende obomvu ngemva kokuqiniswa. Wonke amabhawodi (okuhlanganisa amajoyinti amade nama-circumferential) kufanele aqiniswe ngaphambi kokugcwalisa emuva ukuze kuqinisekiswe ukuthi izingxenye ezigqagqene zika-corrugation zihlanganiswe ngokuqinile ndawonye.

6. Ukuqinisekisa ukuthi inani elidingekayo le-torque ye-bolt liyafinyelelwa, khetha ngokungahleliwe u-2% wamabhawodi kumajoyinti e-longitudinal esakhiweni ngaphambi kokugcwalisa i-backfilling, futhi wenze ukuhlolwa kwesampula nge-wrench ye-torque engashintshi. Uma noma yibuphi ububanzi benani letorque yebhawudi lungafinyeleli inani elidingekayo, khona-ke u-5% wawo wonke amabhawudi akumalunga amalongi nayisiyingi kufanele athathwe isampula. Uma zonke izivivinyo zamasampula ezingenhla zihlangabezana nezidingo, ukufakwa kuthathwa njengokwanelisayo. Uma kungenjalo, kufanele ihlolwe kabusha ukuze kunqunywe ukuthi inani letorque elilinganisiwe liyahlangabezana yini nezimfuneko.
7, Ngemva kokuba amabhawodi ethangeni elihlangene lendandatho yangaphandle eqinisiwe futhi ahlangabezane nezidingo, ukuze kuvinjelwe ukugeleza kwamanzi emithungweni yepuleti likathayela nemigodi yebhawudi, izinto ezikhethekile zokuvala zisetshenziselwa ukuvala isihlanganisi sepuleti lensimbi nezimbobo zamabhawodi ukuvimbela ukugeleza kwamanzi endaweni ehlanganisiwe yepuleti likathayela.
8, ngemva kokuqedwa kokufakwa, epayipini ngaphakathi nangaphandle kwebhulashi lomfaniswano i-asphalt emibili, i-asphalt ingaba i-asphalt eshisayo noma i-emulsified asphalt, ungqimba lwe-asphalt kufanele lube ngaphansi kobukhulu obuphelele be-1mm.
