Ipayipi likathayela likathayelaibhekisela epayipini likathayela elibekwe ekholvethini ngaphansi komgwaqo, ujantshi wesitimela, lenziwe ngepuleti lensimbi le-Q235 lensimbi eligingqiwe noma elenziwe ngensimbi eyizimbongolo eziyindilinga eyisiyingi, kuwubuchwepheshe obusha. Ukuzinza kwayo kokusebenza, ukufakwa okulula, ukuvikelwa kwemvelo okuhle, izinzuzo zezindleko eziphansi zishintsha ngokushesha ukhonkolo wendabuko oqinisiwe ekwakhiweni komgwaqo omkhulu, amathemba okuthuthukiswa abanzi kakhulu, ikakhulukazi asetshenziswa emigwaqweni, amabhuloho, iziteshi, izindonga ezibambile kanye nezimayini ezihlukahlukene, ukusekelwa kodonga olugcina umgwaqo, ukuqiniswa kwamaBhuloho nama-culverts amadala, imigudu, ukwehlisa umsele wokudonsa amanzi, i-scatch hatch namanye amaphrojekthi amaningi.
Izidingo eziyisisekelo zokuhlolwa kwekhwalithi yeipayipi likathayela likathayela
(1) Ipayipi elilodwa likathayela likathayela kufanele lihambisane nesitifiketi sekhwalithi yomkhiqizo lapho uphuma embonini, asikho isitifiketi esiqeqeshiwe okufanele siphume embonini.
(2) Ipayipi likathayela likathayela kufanele lihlolwe iziqephu ngemva kokuba lithuthelwe endaweni yokwakha. Alikho ipuleti lensimbi elikhubazekile elizosetshenziswa ngesikhathi sokuthutha.
(3) Umthamo wokuthwala wesisekelo kufanele uhlangabezane nezidingo zokubala. Ukwemba ngokweqile, ukugcwalisa emuva kanye nokulawula ukuphakama akuvunyelwe ngokuphelele.
(4) ipayipi likathayela likathayela, ukuze kuqinisekiswe ukuthi igxathu elihlangene liqinile, kufanele lihlanze ilunga.
(5) Ukufakwa nokubekwa kwepayipi likathayela likathayela kufanele kube bushelelezi, umthambeka ophansi wepayipi akufanele uhlehliswe, futhi akufanele kube khona inhlabathi, amatshe omatshe kanye nezinye izibi ekholvethi.
(6) Kufanele kuthathwe izinyathelo ezisebenzayo zokuqinisekisa izinga lenhlabathi yamapayipi kathayela agcwaliswa ngemuva.
(7) Ngemva kokuba umshudo oqinile uqinisiwe, inhlanganisela kufanele iboshwe ngezinto ezivinjiwe ezingangeni manzi (noma i-asphalt eshisayo), bese kuba i-anti-corrosion yesibili.
Uma kuqhathaniswa nekholvethi kakhonkolo eqinisiwe, ikholvethi kathayela enalezi zinzuzo ezilandelayo:
1, ipayipi likathayela likathayela kulula ukulinakekela, vele wenze umsebenzi omuhle wokuvikela odongeni lwangaphakathi.
2. Ipayipi likathayela likathayela linezinzuzo ezisobala zezomnotho endaweni yenhlabathi eqandisiwe yasezintabeni nasezindaweni ezithambile zomgwaqo.
3, ipayipi likathayela likathayela emva kokwelashwa kokubola okuqinile.
I-4, ipayipi likathayela likathayela eliqinile ubuqotho, ubucwebe bezimo ze-geological eziyinkimbinkimbi engxenyeni yokumelana nokuguquguquka.
I-5, ipayipi likathayela likathayela elihambisa kahle elishisayo endaweni ye-permafrost yokuphazamiseka kwe-subgrade lincane, ukusimama kombhede womgwaqo.
6, ipayipi likathayela likathayela lamukela ukukhiqizwa kwezimboni, ukukhiqiza akuthintwa imvelo futhi kuhambisana nokulawulwa kwekhwalithi.
I-7, ukwakhiwa komhlangano wamapayipi kathayela kathayela, isikhathi sokwakha esifushane, isisindo esincane, ukufakwa okulula, endaweni ephakeme yokunciphisa inani elikhulu lemanyuwali, futhi ingakhiwa ebusika.
Umkhiqizi wamapayipi kathayela weCulvert
