Rondedzera muchidimbu machinjiro-chikamu mafomu uye maitiro echiteshi

Zvigero zvinowanzoshandiswa mumadhiraini emvura kazhinji ane madhayamita akakura. Kana iyo yemukati dhayamita yakakura kupfuura 3-4m, ivo vanowanzokandwa kana kuvakwa panzvimbo. Zvishandiso zvinoshandiswa zvinosanganisira mapaipi ekongiri, kongiri yakasimbiswa, masonry, zvidhinha zvekongiri, nezvimwe. Kune akawanda machinjiro-chikamu mafomu, asi kazhinji haana denderedzwa. Izvi zvinotevera zvinounza anowanzo shandiswa chiteshi chepakati-chikamu mafomu.

Kana ivhu rekumanikidza uye mutoro zvakakura, iyo semi-elliptical muchinjikwa chikamu inogona kugovera zviri nani pombi rusvingo kumanikidzwa, nokudaro kuderedza pombi rusvingo ukobvu. Kana kuyerera kwetsvina kusachinja zvakanyanya uye dhayamita yechiteshi yakakura kupfuura 2m, rudzi urwu rwemuchinjiko rwakanyanya kukodzera.

Kureba kwechikamu chebhiza idiki pane hupamhi. Rudzi urwu rwechikamu runogona kushandiswa kana geological mamiriro asina kunaka kana nzvimbo yakati sandara uye kudzika kwekuvigwa kunoda kuderedzwa. Sezvo chikamu chezasi chechikamu ichi chakakura, chakakodzera kuendesa tsvina yakakura ine shanduko shoma yekuyerera.

Chikamu chemuchinjikwa chakaita zai chine pasi diki, saka nedzidziso, chinogona kuchengetedza kuyerera kwepamusoro pakuyerera kwakaderera, nokudaro kuderedza siltation. Munguva yakapfuura, yaishandiswa zvakanyanya mumaseji akabatanidzwa. Nekudaro, tsika yakaratidza kuti chiteshi chejecha chechikamu chino chemuchinjikwa chakakomba, uye basa rekugadzirisa uye rekubvisa rakanyanya kuoma.

Iyo rectangular cross chikamu inogona kudzika sezvinodiwa kuti uwedzere kutama. Ichi chikamu chemuchinjiko chinowanzo shandiswa mumatanho etsvina emamwe mabhizinesi emaindasitiri, migero yemvura munzvimbo dzakamanikana dzemigwagwa, uye nzira dzemafashamo. Kubva pane rectangular cross section, inogona kuvandudzwa kugadzira rectangle yakavharidzirwa, arc-bottomed rectangle, concave-bottomed rectangle, nezvimwewo kuvandudza kushushikana uye hydraulic mamiriro. Iyo concave-bottomed rectangular cross cross yepombi chiteshi inokodzera iyo yakasanganiswa sewer system. Pamazuva ekupisa kwezuva, tsvina inoyerera mudiki diki rectangular kuchengetedza imwe dhigirii yekuzara uye kuyerera uye kuderedza dhigirii rejecha.

Zvikamu zveTrapezoidal zvakakodzerwa nematanho akazaruka, uye materu adzo anoenderana nemamiriro evhu uye zvinhu zvekugadzira.

Kazhinji, kana uchigadzira machani eiyo drainage system, kufunga kunofanirwa kupihwa kune mechanics, hydraulics, hupfumi uye kuchengetedza manejimendi zvinodiwa.
