Pasi

Rinokweva mvura dhigiri penyika yokutanga panyika ari kugara kuitika aquifer - iri pasi. Ivo zvisingapindirani kuti vane rusununguko pamusoro, uye pamusoro payo pane kuramba padenga isapinda namatombo. Ivo riri simba uye nokusazvibata matombo. Anogona muzadze makatsemuka iri atadze sedimentary, metamorphic kana igneous matombo, uye zvakare vanovandira Quaternary sediments. Pasi Pevhu maererano zvekufuga yavo dzinoiswa kupinda marudzi akawanda: Dam, musoro uye porous. inotungamirwa yavo kunoitika nokuda infiltration ose pamusoro mvura uye kunayisa. MUNDA Kuvapo kwavo kazhinji rinobatana kuparadzirwa aquifer, simba zvisina dzose, asi zvinoenderana romugove zvikuru, daro kuti okuyerera kunharaunda mvura-ine matombo, etc.

Pasi Pevhu vane chikuru chinhu chinosiyanisa kubva chitubu, mvura zvakadzama - nokushayiwa dzvinyiriro. Vanobatwawo okunze: tembiricha, kwemvura uye kumanikidzwa, kwemvura, etc. Uyewo kune zvakakosha zvaiitwa ezvoupfumi mabasa munhu ari kupomba nemafuta uye mvura kubva kwakadzika, kuvaka kudiridzwa uye abudise uye hydraulic ezvirevo . Fetiraiza / kurima nyika, migodhi, etc. Uyezve hydraulic ezvinhu zvinokosha: shanduko zvikasabudiswa rudzi, kugoverwa uye pamusoro mvura miviri.

Kuvakwa zvaparadzwa pasi, wakaipa kubatsira kongiri nezvimwe zvokuvakisa. Usati watanga afunge zvivako zvakakodzera kuita nzvimbo yokuverengera, ane pfungwa rwakabhadharwa kuna kuvapo, hunhu, makemikari anoumba (sehasha) Pasi Pevhu, uyewo anokarirwa kugadzirwa mvura. Sehasha Akatsunga solubility calcium carbonate uye dzinoongororwa nokuda zvinotevera madhigirii: obschekislotnaya, leaching, magnesia, sulphate uye carbon dioxide.

Nokuti nyika upfumi, mvura aya zvikuru sezvo mungabva mvura remaguta, maindasitiri zvivako, etc. Vari zvinoberekwa kuchera matsime uye matsime norukangarabwe nokurasa tichibatanidza pamwe grids dzakarukwa ruka. Ndezvipi ngozi? Kuwanikwa pasi rinokutadzisa Kuzadziswa nomunhu kuvakwa pezvakaitwa Somuenzaniso: kusarudza nheyo, kuvapo imwe Uriri, bhesimendi, pakavanda, kana munhu septic tangi.

Ground mvura yepasi tunodzivisa nedanho kupikidura, nokuti kunoshayisa ivhu uye usarega kuita kuvaka. Walls kurasikirwa kubereka vanokwanisa nokuti chokuti caissons wedzimba uye mudzimba kuchinjwa hydrostatic kumanikidzwa, tightness akarasika. Ground mvura yepasi yekudyidzana kukanganisa simba hwaro, uye kuwedzera, zvinoda matanho dzokuwedzera unodzivirira: voga kubva rirambe richibvira mwando panguva uriri sandara, kudzivirirwa masvingo kaviri pakuuyiwa nebwe riri nesuko, hwakakanyiwa inopisa bhitumini kana simende dhaka chete Uyezve gidrozita. Kubva kumanikidzwa mvura kudzivirira zvivako vanopedza mudziyo drains the uye mvura yaunodya, uyewo kuburikidza nokuumba isapinda Kamudzira masvingo uye bhesimendi paburiro.

Kutsunga of pasi pamwero rinotanga kuwana aquifer. On a sandara pamusoro kana chikamu ndizvo chete kwose kwose, uye kana roughness pamwero rinopfuura kumusoro uye nechepasi vanomutswa nzvimbo - mune dzegirini. Kazhinji vanenge riri chinhambwe 20 m, mu wetlands - 1 M Kana mvura anozadza nharaunda shoma dzegirini, ayo sandara iri pamusoro pasi pamusoro .. In ekunze kuchinaya, aenzane kunowedzera, uye kusanaya kwemvura - ipfupi.

Pakusarudza padanho pasi iri rinokosha nokuda kuvaka uye nheyo. Kubva ichi kuvimba kubereka vanokwanisa ivhu. Kana pamwero hahusvikirwi, muzadze zimba iri zvaisambobvumirwa kubereka.
