Curb drainage migero zvinhu zvakakosha zvekugezesa migwagwa.Vanounganidza uye kutungamira mvura inonaya kubva mumugwagwa, kuve nechokwadi chekushanda kwakakodzera kwenzira yemvura yemugwagwa uye kudzivirira kuunganidza kwemvura uye kukukurwa.Mamiriro emvura ekuvharisa migero yemvura anoratidzwa pazasi.
Chekutanga, migero yedhiraivha ine mvura yakanaka.Magadzirirwo uye kuvakwa kwematanho anobvumira kukurumidza uye kwakanyatso kuunganidzwa kwemvura inonaya kubva mumugwagwa, uye ivo vanofambisa kuyerera kwakakodzera mukati mehurongwa.Iyo lateral uye longitudinal slopes yematanho inofanirwa kuve yakakodzera kuti ivimbise yakatsetseka uye isina kuvharika kuyerera kwemvura.
Pamusoro pezvo, kuchinjika-chikamu chimiro chemigero yemvura inokanganisawo kugona kwavo kwemvura.Maumbirwo akajairika anosanganisira "V" -yakaumbwa, rectangular, uye trapezoidal.Aya maumbirwo anowedzera kushanda kwemvura.Uyezve, kuisa matombo akasununguka kana zvimwe zvinhu zvine porous pazasi pematanho zvinogona kuwedzera permeability uye kunatsiridza kuita kwemvura.
Chechipiri, migero yekugezera mvura ine inogadziriswa drainage capacity.Vanoda kukwanisa kugadzirisa mvura yavo yemvura zvichienderana nekunaya kwakasiyana kwemvura uye zvinodiwa nemigwagwa.Munguva yemvura yakareruka, migero inofanirwa kuunganidza nekukasira nekubvisa mvura inonaya.Kana kunaya kwemvura zhinji, migero inofanira kunge iine simba rekubata mvura yakawanda.Kuburikidza nedhizaini yakakodzera uye kushivirira, zviteshi zvinogona kudzivirira kuvhara uye kufashukira.
Naizvozvo, panguva yekugadzira nekuvaka maitiro, zvinhu zvakaita sehukuru, kudzika, uye kureba kwenzira dzemvura dzinofanirwa kutariswa zvichibva pane chaiyo nharaunda uye zvinodiwa.Izvi zvinova nechokwadi chekuti machani ane chinogadziriswa drainage capacity.
Chechitatu, nzira dzemadhiraivha dzine hunyanzvi hwekuzvichenura.Pamusoro pekugona kwavo kudonhedza mvura nekukurumidza uye nemazvo, ivo vanofanirwawo kuve nekuzvichenesa kuita kuti vachengetedze nzira dzisina kuvharwa.Kuzvichenesa kunonyanya kuvimba nekuyerera kwemvura, saka magadzirirwo emagero emvura anofanirwa kufunga nezve velocity uye kuyerera kwemvura.Kana kuyerera kwemvura kwakadzikira zvakanyanya, zvinogona kukonzera kuunganidzwa kwemvura uye kuisa madhamu.Sezvineiwo, kana kuyerera kwemvura kwakakwira zvakanyanya, zvinogona kukonzera kukweshwa kwepasi nemativi, zvichikonzera kusvibiswa kwechipiri.
Munguva yekugadzira nekuvaka, zvinofanirwa kufunga nezve mafashama frequency uye nhoroondo yemafashama mazinga munzvimbo dzakasiyana.Nekusarudza hurefu hwakakodzera, hukuru, uye masimba emvura enzira dzekuvharisa mvura, kudzivirira mafashama enzira yemvura yemumugwagwa inogona kuvandudzwa.
