Mukugadzira matuneri, sisitimu yekudhonza mvura yakakosha zvikuru. Mambure ekudhonza mvura ane mativi matatu anoshandiswa zvakanyanya mukugadzira matuneri. Saka, mashandisirwo awo mutuneri ndeapi?
I. Hunhu hwehunyanzvi hwemambure emvura akabatanidzwa ane mativi matatu
Mambure ekudhonza mvura ane mativi matatu akagadzirwa nesimbi yepurasitiki ine mativi matatu yakagadzirwa nepolyethylene ine mativi maviri (HDPE) uye geotextile inopindika inobatidzwa nemativi maviri. Chimiro chayo chepakati inzira yekudhonza mvura inoumbwa nembiru dzakamira uye mbabvu dzepamusoro nedzepasi dzinotsigira kuti igadzire sisitimu yekutsigira yakagadzikana. Nokudaro, ine zvakanakira zvitatu zvikuru zvehunyanzvi:
1. Kukwanisa kuburitsa mvura zvakanaka: Kupinda kwemvura kunogona kusvika 2500m/d, zvakaenzana nemhedzisiro yekuburitsa mvura kubva muvhu rakakora remamita imwe, uye zvinogona kukurumidza kuburitsa mvura inoyerera mugomba.
2. Kuramba kudzvanywa kwakanyanya: Inogona kutsungirira mutoro wekudzvanywa kwakanyanya we3000kPa kwenguva yakareba, ukobvu hwepakati pe mesh i5-8mm, uye simba rekudzvanywa i ≥36.5kN/m, zvichiita kuti ishande zvakanaka mumamiriro ezvinhu akaomarara e geology.
3. Basa rekudzivirira rakakwana: Rine mabasa ekudzivirira kusefa, kupinza mhepo, uye kusimbisa hwaro, zvichigadzira sisitimu yekudzivirira yakabatana ye "kudzivirira-kusefa-kudhonza-mvura".
II. Zviitiko zvina zvikuru zvekushandisa muinjiniya yemugero
1. Dura rekudhonza mvura riri shure kwejira remukati
Kumanikidzwa kwemvura kunokonzerwa nekuungana kwemvura pasi pevhu kuseri kwegomba remugero, zvichikonzera kudonha kwemvura uye kutokuvadzwa kwechivako. Mambure ekudhonza mvura ane mativi matatu anoiswa pakati pegomba nedombo rakatenderedza kuti agadzire nzira yekudhonza mvura inotungamira mvura yemugomo ichipinda mugomba repadivi kuti ibudiswe.
2. Sisitimu yekudhonza mvura yakachinjika
Chigadziko chakatenderedzwa chinogona kukonzera chando nekuda kwekuungana kwemvura. Mumbure wekudhonza mvura une mativi matatu unoshandiswa pamwe chete nejecha kuti ubvise mvura iri pasi pevhu nekukurumidza. Chimiro chayo chine mativi matatu chinogona kudzivirira kukwira kwemvura mumapapu uye kudzivirira kukuvara kwechando munguva yechando.
3. Rutivi rwekudhonza mvura pamadziro eparutivi
Mugomba rine dombo rakakomberedza risina kusimba, mvura inoyerera mumadziro eparutivi inogona kukonzera nyore nyore kuti chimiro chekutsigira chisagadzikana. Sechikamu chekuyerera kwemvura pamadziro eparutivi, jira remvura rine mativi matatu haringogoni chete kuburitsa mvura inoyerera, asiwo kudzikamisa kushanduka kwedombo rakatenderedza kuburikidza nesimba raro rekudhonza. Ruzivo rwekuyedza runoratidza kuti simba raro rekuchekerera rakakwirira ne40% kupfuura rezvinhu zvechinyakare, izvo zvinogona kuve nechokwadi chekuti madziro eparutivi akasimba.
4. Dura rekuchinja kwemvura yechiteshi chemugero
Nzvimbo yemugero inogona kuputsika nekuda kwekupinda kwemvura pamusoro. Mugero wemugero une mativi matatu wakaiswa kuseri kwenzvimbo yemugero kuti ugadzire nzvimbo yekuchinjana mvura inotungamira mvura pamusoro pemugero wemvura. Kusagadzikana kwayo nengura kunogona kudzivirira kukurwa kwemvura yepasi pevhu ine acidic uye kuve nechokwadi chekuti mvura inogara kwenguva refu.
III. Nzvimbo dzekuvaka uye kudzorwa kwemhando
1. Kudzora nzira yekuisa: Kureba kwenzira yemupumburu wezvinhu kunofanirwa kunge kwakatarisana nepakati pemugero wemvura kuti ive nechokwadi chekuti nzira yekubuditsa mvura inoenderana negwara remvura.
2. Kugadzirisa majoini: Shandisa tekinoroji yekubatanidza mabuckle kana welding kugadzirisa, kureba kwekubatana kwacho kuri ≥15cm, uye shandisa zvipikiri zvakaita seU kana mabhandi epolymer kubatanidza 0.3m yega yega.
3. Kudzivirira kuzadza: Kuzadza kuzadza kunofanira kupedzwa mukati memaawa makumi mana nemasere mushure mekuiswa, saizi yepamusoro yezvidimbu zvekuzadza i ≤6cm, uye kudzvanywa kwemuchina kwakapfava kunoshandiswa kudzivirira kukuvara kwechimiro chepakati pe mesh.
