Kugwiritsa ntchito chitsulo cha malata paipi culvert mu uinjiniya wa misewu yayikulu

Chitoliro cha malata cha malata, wotchedwansobomba la culvert,ndi achitoliro chamalatakwa makoma oikidwa pansi pa misewu ikuluikulu ndi njanji.malata chitoliroamatengera mapangidwe okhazikika, kupanga pakati, kadulidwe kakang'ono kakupanga; pa malo unsembe wa zomangamanga ndi mbiri unsembe angagwiritsidwe payokha, nthawi yochepa yomanga, pa nthawi yomweyo kuchepetsa kapena kungotaya zomangira wamba, kuteteza chilengedwe ndi kutali; ndipo ali ndi azolowere mapindikidwe maziko, mphamvu zinthu ndi wololera, kuchepetsa ubwino wa kukhazikikana osagwirizana, kuthetsa vuto la kuwonongeka kwa kapangidwe konkire milatho ndi culverts chitoliro m'madera ozizira.

Mivuto yachitsulo yopangidwa ngati Arch

Zozungulira anasonkhana zitsulo mvuto

Mivuto yachitsulo yokhala ngati nsapato ya akavalo

Chitoliro woboola pakati zitsulo anasonkhana mvuto

 

Malinga ndi kafukufukuyu, moyo wautumiki wa zitsulo zachitsulo ukhoza kukhala zaka zoposa 100 chifukwa cha chithandizo cha malata ndi mankhwala a asphalt anti-corrosion. Gawo la chitoliro chosonkhanitsidwa limatengera Q235-Mbale yotentha yotentha yachitsulo, ndipo bwalo lililonse limakhala ndi mbale zingapo zachitsulo zolumikizidwa kuti zipange zonse, kenako zimalumikizidwa nthawi yayitali ndikuwumbidwa. Maboti olumikizira amatenga ma bolt amphamvu kwambiri a M 208.8 ndi ma washer opindika a kalasi ya HRC35, pamwamba pazitsulo zachitsulo ndizitsulo zotentha, zolumikizira mbale zimasindikizidwa ndi zida zapadera zosindikizira, maziko a chitoliro cha chitoliro ndi zofunda za miyala 50-100cm, zokhala ndi chofunda. kuphatikizika kwa N95%, ndipo pobowoyo amapangidwa ndi miyala ya M7.5 slurry masonry, ndipo otsetsereka a chitoliro chamadzi oyenda pamwamba pamadzi ndi 5%. General malata zitsulo culvert kuwonjezera pamwamba chitoliro mtundu, pali elliptical, flange mtundu unsembe wathunthu, etc., kuitanitsa ndi kutumiza kunja akhoza kupangidwanso malinga ndi gawo la mbali otsetsereka beveled.

Kuchuluka kwa ntchito
Quick Passage Project
Msewu woopsa pafupi ndi phiri
Galimoto-oyenda pansi
Pamwamba mudzaze mapiri
Dziko lozizira, lodzaza kwambiri
Kukhuta mozama, kupezeka kwa ziweto
Njira zakumunda ndi zakumunda
ulimi wothirira
Mapiri olemera
Malo oundana, ozama komanso osazama
Malo opanda mgodi wa malasha
Kunyowa kupsinjika maganizo, kukhuta kwambiri
Kudzaza kosaya, m'malo mwa milatho yaying'ono
Kukhuta kwakukulu, kunyowa konyowa, maziko otsikakubereka mphamvu
