Kushandiswa kwesimbi yemarara pombi culvert muhighway engineering

simbi yemarata culvert pipe, anonziwoculvert pipe,ndi amarata pombikumakombi akaiswa pasi pemigwagwa mikuru nenjanji.marata simbi pombiinotora yakamisikidzwa dhizaini, yepakati kugadzirwa, pfupi kugadzirwa kutenderera; pa-saiti kuiswa kweinjiniya yehurumende uye kuiswa kweprofile kunogona kuitwa zvakasiyana, nguva pfupi yekuvaka, panguva imwe chete kuderedza kana kungorasa zvakajairwa zvekuvaka, kuchengetedza kwezvakatipoteredza kunosvika kure; uye inofanirwa kuchinjika kune deformation yenheyo, iyo simba mamiriro inonzwisisika, kuderedza zvakanakira kusaenzana kugadzikana, kugadzirisa dambudziko rekukuvadza kune kongiri chimiro chemabhiriji uye pombi culverts munzvimbo dzinotonhora.

Arch-shaped akaungana simbi mabhero

Circular yakaungana simbi mabhero

Mabhero esimbi akaita sehorseshoe

Pipe arch-shaped akaungana simbi mabhero

 

Maererano neongororo iyi, hupenyu hwebasa remabhero esimbi hunogona kupfuura makore zana nekuda kwekurapwa kwemarara uye asphalt anti-corrosion kurapwa. Iyo yakaunganidzwa corrugated pombi chikamu inotora Q235-A inopisa yakakungurutswa simbi ndiro, uye imwe neimwe denderedzwa ine akati wandei simbi mahwendefa akabatanidzwa kuti aumbe akazara, obva abatanidzwa kwenguva refu uye akaumbwa. Mabhaudhi ekubatanidza anotora M 208.8 giredhi yakakwira simba mabhaudhi uye HRC35 giredhi rakakomberedzwa washers, pamusoro pesimbi ndiro inopisa-dip galvanized, majoini eplate akaiswa chisimbiso nezvinhu zvakakosha zvekuisa chisimbiso, hwaro hwepombi culvert ndeye 50-100cm matombo ekurara, ane compactness yeN95%, uye gomba paving rakagadzirwa neM7.5 slurry masonry chidimbu dombo, uye mutsetse wepombi culvert inoyerera pamusoro pemvura i5%. General corrugated simbi culvert mukuwedzera kune iri pamusoro pombi mhando, kune elliptical, flange mhando yekuisa kuisirwa, nezvimwewo, kupinza uye kutumira kunze kwenyika kunogonawo kuitwa zvinoenderana nechikamu chedivi rakatenuka.

Chikamu chekushandisa
Quick Passage Project
Mugwagwa une ngozi pedyo negomo
Kusvika kwemotokari-vanofamba netsoka
Kuzadza kwakakwirira munzvimbo dzine makomo
Nyika yechando, kuzara kukuru
Kuzadza kwakadzika, kuwana zvipfuyo
Munda nemakorokoto emadhorobha
Kudiridza kwekurima
Makomo anorema
Ivhu rakaomeswa, rakadzika uye risina kudzika kuzadza
Mugodhi wemarasha
Wet depressional loss, high fill
Kuzadza kwakadzika, kutsiva mabhiriji madiki
Kuzadzwa kwepamusoro, kunyorova, kuderera kwehwarokutakura kugona
