Kuwonekera kwamitundu kosasunthika kumatha kupangitsa chilengedwe kukhala chokongola, komanso kumalimbikitsa chitetezo chamsewu, chomwe chimagwiritsidwa ntchito mochulukirachulukira.kumanga m'magawo ena amsewu onyowa, njira yapitayi siyingagwiritsidwe ntchito pomanga, komanso kukhudzidwa kwa kutentha kwa madzi. ziyenera kuganiziridwa panthawiyi.
Zomatira zamtundu wosatsetsereka zimagwiritsidwa ntchito m'misewu yonyowa pang'ono komanso yonyowa komanso kutentha kwambiri. Chifukwa wosanjikiza pamwamba si mpweya, madzi anaunjikira mu roadbed ndi m'munsi wosanjikiza chifukwa cha kutentha ndi chinyezi gradient sangathe kuchotsedwa pamwamba wosanjikiza. Kusakhazikika kwamadzi kumachepetsa mphamvu ndi kukhazikika kwake ndikuyambitsa kuwonongeka kwa msewu. Nthawi zambiri, zida zokhala ndi madzi okhazikika ziyenera kusankhidwa ngati maziko amiyala yokongola yosatsetsereka, makamaka misewu yonyowa komanso yonyowa. Kuphatikiza apo, mumsewu wonyowa komanso wonyowa kwambiri wokhala ndi mikhalidwe yoyipa ya hydrogeological, kuwonjezera pakulimbitsa ngalande zamsewu, njira zaukadaulo monga laimu wocheperako wokhazikika kumtunda kwa dothi lopanda msewu kapena kuwonjezera ma cushion granular angagwiritsidwe ntchito pochiza. kukonza kutentha kwa madzi amsewu.
M'madera oundana omwe ali ndi kuya kwakukulu kozizira, pamene nthaka ya roadbed ndi dothi lopanda chisanu mosavuta, kuopsa kwa chisanu ndi kuwira kwa matope kuyenera kuganiziridwa. Kudziwa makulidwe okwana a msewuwo, kuwonjezera pa kukwaniritsa zofunikira za mphamvu zamakina, ziyeneranso kukwaniritsa zofunikira za makulidwe a antifreeze wosanjikiza kuti mupewe ayezi wochuluka omwe akusonkhanitsa madera mkati mwa msewu, zomwe zimapangitsa kuti pakhale chisanu chosiyana. kukwera ndi kusweka kwa msewu. Mukamagwiritsa ntchito zomatira zamtundu wa anti-skid pomanga misewu yonyowa, tiyenera kulabadira zomwe zimatengera kutentha kwa madzi, apo ayi zitha kukhudza kwambiri kugwiritsidwa ntchito kwapanjira kotsutsana ndi skid, ndipo kungakhudze moyo wautumiki. .
