Ko network yemvura inoyerera ine mativi matatu inogona kudzivirira kuzara kwevhu uye kuvharika kwevhu here?

Mumainjiniya, dambudziko rekudonha kwevhu rave richikosha zvikuru. Network yekudonha kwevhu ine mativi matatu. Iyi imhando yemvura inoshandiswa zvakanyanya mumapurojekiti makuru. Saka, inogona kudzivirira kudonha kwevhu nekuvharika kwevhu here?

1. Kugadzira zvinhu zvitsva muchivako

Network yekudhonza mvura ine mativi matatu Inoumbwa negeotextile ine mativi maviri uye geotextile ine mativi matatu. Mesh core yakagadzirwa nepolyethylene ine density yakakwira (HDPE) Maitiro ekuumba mativi matatu anoumba network ye criss-crossing rib, uye kusiyana kwayo kunoratidzwa muzvikamu zviviri zvinotevera:

1、Sisitimu yeGradient Pore: nzvimbo yepakati pembabvu dzakamira pakati pemesh core ndeye 10-20 mm， Mbabvu yepamusoro yakatsveyama nembabvu yepasi zvinoumba nzira yekutsveyamisa ine mativi matatu, iyo inoenderana nedhizaini yegradient ye aperture ye geotextile (chikamu chepamusoro 200 μm， Chikamu chidiki 150 μm）， Saizi yezvikamu zvinogumira inogumira kupfuura 0.3 mm yezvikamu, Real Now "coarse filtration-fine filtration" yakarongwa kutsveyamisa.

2、Dhizaini yekudzivirira kupinza: ukobvu hwembabvu dzesimbi dzesimbi dzinosvika 4-8 mm， Mu 2000 kPa. Zvinopfuura 90% yeukobvu hwepakutanga hunogona kuramba hwakachengetwa pasi pemutoro, kuitira kudzivirira geotextile kuiswa mumesh nekuda kwekumanikidzwa kwenzvimbo. Zvinoenderana nedata reinjiniya renzvimbo yekurasira marara, mushure memakore mashanu ekushandiswa, dhayeti yemvura inoshandisa chinhu ichi ichafambisa mvura. Rate attenuation rate i8% chete, iyo yakaderera zvikuru pane 35% ye gravel layer yechinyakare.

2. Hunhu hwezvinhu

1、Kugadzikana Kwemakemikari: HDPE Mesh core inodzivirira acid ne alkali corrosion. Mu pH Munzvimbo isina acid ne base isina simba ine kukosha kwe4-10, kugadzikana kwechimiro chayo che molecular structure kunopfuura 95%. Polyester yakasanganiswa Filament geotextile Kupfeka kunodzivirira UV kunogona kudzivirira kukwegura kwezvinhu kunokonzerwa nemwaranzi yeUV.

2、Maitiro ekuzvichenesa: kuomarara kwenzvimbo ye mesh core Ra. Kukosha kunodzorwa pa3.2-6.3 μm. Mukati menzvimbo yacho, haingogone chete kuve nechokwadi chekuti mvura inoyerera zvakanaka, asiwo kudzivirira kunamira kwe biofilm kunokonzerwa nekunyorova kwakanyanya.

3. Kudzidzira zveinjiniya

1、Kushandiswa kwekuisa marara: Munzvimbo inorasirwa marara ine simba rekugadzirisa matani 2,000 zuva nezuva, network yekubvisa marara ine mativi matatu uye HDPE membrane inoita sisitimu inodzivirira kunyura kwemvura. Nheyo yayo ine mativi matatu inogona kumira 1500 pazuva m³Mutoro we leachate, pamwe chete nebasa re geotextile rekumashure, unogona kuyerera. Mvura inoburitswa nenzira imwe chete, izvo zvinogona kudzivirira madhaka kuti asadzokere shure. Mushure memakore matatu ekushanda, kukosha kwekudonha kwe drainage laminate kunongova 0.05 MPa chete, pasi pemuganho wekugadzira we 0.2 MPa.

2、Kushandiswa kweinjiniya yemigwagwa: Mumugwagwa mukuru munzvimbo ine ivhu rakaomeswa nechando kuchamhembe kweChina, inogona kushandiswa sechikamu chemvura inoyerera pasi pevhu, izvo zvinogona kuderedza huwandu hwemvura yepasi pevhu ne1.2% nekudzivirira kukwira kwemvura ye capillary m。 Kuomarara kwepakati pe mesh core yayo i120 kN/m², Inogona kuderedza kutama kwechikamu che base uye kuderedza kuitika kwe blind cracks. Kutarisa kunoratidza kuti kuwanda kwezvikamu zvemugwagwa zvinoshandisa tekinoroji iyi kwakaderera ne67% zvichienzaniswa nezvirwere zve subgrade zvechinyakare, uye hupenyu hwebasa hunowedzerwa kusvika kumakore anopfuura makumi maviri.

3、Kushandiswa kweinjiniya yeTunnel: Mugwagwa wechitima unopfuura nepakati pema stratum ane mvura yakawanda, network yemvura inosanganiswa ine mativi matatu uye keteni regrouting zvinoshandiswa pamwe chete kugadzira sisitimu isingapindi mvura ye "kubatanidza mvura inoyerera uye inovhara". Huremu hwayo hune hydraulic conductivity ye2.5 × 10⁻³m/s, Plate yemvura yechinyakare. Wedzera katatu, shandira pamwe nejira re geotechnical. Basa rekusefa rinogona kuderedza njodzi yekuvharika kwehurongwa hwemvura inoyerera mugwagwa ne90%.

4. Maitiro ekugadzirisa

1、Internet of Things monitoring: Ma sensor e optical fiber akaiswa mu drainage network kuti aongorore ma parameter akadai se hydraulic conductivity, stress uye strain munguva chaiyo.

2. Kugadzirisa jeti remvura rine pressure yakakwira: nzvimbo dzakavharika munharaunda, shandisa 20-30 MPa jeti remvura rine pressure yakakwira kuti rigadzire drag. Chimiro chembabvu chepakati pe mesh chinogona kutsungirira kumanikidzwa pasina kuchinja, uye mwero wekudzoreredza kwe hydraulic conductivity mushure mekugadziriswa unopfuura 95%.
