Viaduct - mlatho kapena ayi?

Bridges, overpasses, flyovers, viaducts - mawu onse ali ofanana. Komanso, iwo akuimilira ndi ogwira ntchito zofanana kwambiri yomanga, chimagwiritsidwa ntchito mwa munthu malonda ake. Kusiyanitsa pakati pa mfundo izi, ndipo amapereka zinthu zazing'ono.

mlatho

Kamangidwe kameneka zomangamanga, anatulukira kalekale. Mmodzi wa masiku akale kuchokera chakhumi ndi chitatu m'ma BC. Kuyambira kale, anthu ayamba kumanga milatho mavuto madzi monga mitsinje, nyanja, madambo, etc. Choncho, osati ndi mawu ambiri ntchito mwa akufuna, komanso wamkulu. M'lingaliro waukulu, ndi zina zonse zatchulidwa ndi milatho, choncho anafunsa mu udindo, ayenera kuti ayankhidwe "inde." Komabe, pali "koma." Za iye pang'ono.

malo ichi, chamangidwa pa njira zina, koma iwo sakutchedwa mlatho chifukwa mwaukadaulo pali kusiyana kwambiri iye. Choyamba iwo amayamba chifukwa chakuti kamangidwe ka overpass mulibe ayenera kuganizira zotsatira za zochitika zosiyanasiyana zachilengedwe kugwirizana ndi watercourse ndi imapezeka pansi pa mlatho. Choncho amathandiza chilengedwe cha mfundo Pankhaniyi losiyana wachibadidwe. Ife sitikhala wofufuza tsatanetsatane luso, ife kukumbukira zinthu zitatu zokha, zomwe mutu pa milato okonza. Izi kumatula kwa ayezi, eroding ndi zombo zambiri kudutsa pansi. Overpass - Ndipotu, mlatho kudacita. Choncho, tili ndi mawu lina malo ichi. Pagona yaing'ono "koma" woyenera ntchito mawu akuti "mlatho" mu mtima wa overpass lapansi.

overpass

Ngati yomanga overpass ndi kumafunika utali awiri kapena anayi mamita 10-30 kutalika lililonse, kuti kuika trestle ndi zambiri zofunika kwambiri a iwo. Ndipotu, pali kusiyana lonse pakati pa nyumba ya zomangamanga. Komabe, mfundo zofunika pano ali kuti potsegula nsanja akhoza kuwoloka mitundu angapo zopinga Mwachitsanzo, kungakhale mtsinje, msewu ndi sitima mayendedwe pa nthawi yomweyo, motero kaphatikizidwe mwa iye mwini ndi mlatho ndi overpass.

Taonani mtundu zotsatirazi mlatho. Pali mtundu wina wa mavuto ndi mwapadera kwa anthu amene afotokozedwa kale kale. Izi pazikhalanso zigwembe, m'zigwa, zigwembe. Choncho, palibe zosatheka kugwiritsa ntchito mawu akuti "overpass". Ndi wosiyana ndi dongosolo mlatho - ndi viaduct. Taganizirani mbali yake.

Ntchito yomanga viaducts m'malo misewu ikuluikulu yilungamitsidwa pa nthawi imene zachuma inexpedient kulenga mulu. Kuti onse anatsimikiza mtima kuya kwa chigwa, ndipo kutalika kwake mu mbiri ya zilipo njira zina zamayendedwe. Choncho, kusiyana kwa viaduct trestle kulibenso kapena zochepa lathyathyathya pamwamba pansi pa mlatho. Chifukwa chinthu ichi, yofanana zogwiriziza ndi utali Pankhaniyi salinso abwino. Viaducts amakhala - wokongola kwambiri ndi otchuka nyumba. Mwachitsanzo, kutalika kwa mmodzi wa mizati ya viaduct dziko apamwamba Millau pafupifupi 340 meters.

Kupitiriza ndi phunziro lathu, tiyenera anganene nyumba ina chidwi Ngakhale kuti distantly yekha zokhudza mfundo monga overpasses ndi misewu. Izi otchedwa ngalande. Izi analogous kuti viaduct, koma kwa kulanda madzi, m'malo magalimoto pa chigwa cha, mtsinje kapena chopinga zina, kawirikawiri kukhala mbali ya dongosolo ulimi wothirira.

Pomaliza

Tikaonanso funso limene lili pa mutu, yankho komaliza kwa izo. Inde, viaduct - mlatho pa mfundo za zomangamanga, ndipo, monga mmene sanalengedwe pa ngozi madzi, ndi pa msewu ofanana. Imeneyo ndiyo dialectic.
