Gedhi resimbi rinochera mvura muchimiro chesimbi chinhu chakakosha pakudzora huwandu hwemvura muzvivakwa zve hydraulic zvakaita se hydropower station, reservoir, sluice uye ship lock. Rinofanira kunyudzwa pasi pemvura kwenguva yakareba, nekuchinjwa kwakaoma nekunyorova nguva nenguva pakuvhura nekuvhara, uye kugezwa nekuyerera kwemvura nekukurumidza. Kunyanya, chikamu chemvura chinokanganiswa nemvura, chiedza chezuva nezvisikwa zvemumvura, pamwe nemafungu emvura, sediment, ice nezvimwe zvinhu zvinoyangarara, uye simbi iri nyore kuonda, Inoderedza zvakanyanya kugona kwekutakura kwegedhi resimbi uye inokanganisa zvakanyanya kuchengetedzeka kwe hydraulic engineering. Mamwe anodzivirirwa ne coating, iyo inowanzo kundikana mushure memakore 3 kusvika 5 ekushandiswa, nekushanda kwakaderera uye mutengo wakakwira wekugadzirisa.

Kuora hakungokanganisi chete kushanda kwakachengeteka kwechivako, asiwo kunopedza vanhu, zvinhu uye mari yakawanda pakuita basa rekudzivirira ngura. Zvichienderana nehuwandu hwemamwe mapurojekiti egedhi rekudzivirira ngura, mari inoshandiswa pagore yekudzivirira ngura yegedhi inokwana hafu yemari yekugadzirisa yegore negore. Panguva imwe chete, vashandi vakawanda vanofanira kuunganidzwa kuti vabvise ngura, pendi kana spray. Saka, kuitira kudzora ngura yesimbi zvinobudirira, kuwedzera hupenyu hwebasa regedhi resimbi uye kuona kuti mapurojekiti ekuchengetedza mvura nemagetsi emvura akachengeteka, dambudziko renguva refu rekudzivirira ngura yegedhi resimbi rakakwezva vanhu vakawanda.

Nzvimbo yengura yesimbi yakagadzirwa nesimbi ine sluice gedhi uye zvinhu zvinokanganisa ngura:

1. Nzvimbo yengura yesimbi yakagadzirwa nesimbi

Mamwe magedhi esimbi anodonhedza mvura uye zvivakwa zvesimbi mumapurojekiti ekuchengetedza mvura nemagetsi emvura zvinonyudzwa mumhando dzakasiyana dzemvura (mvura yegungwa, mvura yakachena, mvura yakasviba yemaindasitiri, nezvimwewo) kwenguva yakareba; Mamwe anowanzova munzvimbo yakaoma ine mvura nekuda kwekuchinja kwehuwandu hwemvura kana kuvhurwa nekuvharwa kwegedhi; mamwe achakanganiswawo nekuyerera kwemvura nekukurumidza uye kukweshana kwematope, marara anoyangarara uye chando; Chikamu chiri pamusoro pemvura kana pamusoro pemvura chinokanganiswawo nemhepo ine hunyoro yekubuda kwemvura uye mhute yemvura inopfachukira; Zvivako zvinoshanda mumhepo zvinokanganiswawo nezuva nemhepo. Nekuti nzvimbo yekushanda yegedhi re hydraulic yakaipa uye kune zvinhu zvakawanda zvinopesvedzera, zvakakosha kuongorora zvinhu zvinokonzera ngura.

2. Zvinhu zvinokonzera ngura

(1) mamiriro ekunze: zvikamu zvemvura zvechivakwa chesimbi zviri nyore kupiswa nezuva, mvura uye mhepo ine hunyoro.

(2) mamiriro epamusoro pesimbi: kuomarara, kukuvara kwemuchina, kuvharika kwesimbi, zvikanganiso zvekunamira, maburi, nezvimwewo zvine simba guru pakuora.

(3) kushushikana nekushanduka: kana kushushikana nekushanduka kukawanda, ngura inowedzera kuipa.

(4) Hunhu hwemvura: huwandu hwemunyu mumvura yakachena hwakaderera, uye ngura yegedhi inosiyana zvichienderana nekugadzirwa kwayo nemakemikari uye kusvibiswa; Mvura yegungwa ine huwandu hwakawanda hwemunyu uye conductivity yakanaka. Mvura yegungwa ine huwandu hwakawanda hwe chloride ions, iyo inokuvadza zvakanyanya simbi. Kuora kwegedhi resimbi mumvura yegungwa kwakakomba kupfuura kuri mumvura yakachena.
