Zvakanakira nekuipira kwenetwork dzemvura dzakasanganiswa

Network yemvura inoshandiswa mumigwagwa, nzvimbo dzekurasira marara, kugadzira nzvimbo dziri pasi pevhu nemamwe mapurojekiti. Saka, ndeapi mabhenefiti ayo neakaipa?

一. Zvakanakira zvikuru zvecomposite drainage network

1, Kushanda zvakanaka kwemvura

Mambure ekudhonza mvura akagadzirwa necomposite anoshandisa chimiro chepakati chemesh chine mativi matatu (ukobvu hwacho hunowanzova 5-8 mm）， Mbabvu yepakati inomira inoumba nzira yekudhonza mvura inoramba ichienderera mberi ine rutsigiro rwakarerekera, uye kushanda kwemvura kunopfuura ka5-8 kupfuura jira remajecha rechinyakare. Sisitimu yayo yekuchengetedza maburi inogona kutsungirira mitoro yakakwira (3000 kPa Compressive load) inochengetedza hydraulic conductivity yakasimba, uye displacement per unit time inogona kusvika 0.3 m³/m²，Inonyanya kukodzera mamiriro enzvimbo akadai senzvimbo dzevhu dzakaoma uye soft foundation treatment.

2, Simba guru uye kuramba kwekushanduka

Yakagadzirwa ne polyethylene ine density yakakura (HDPE) Mesh core yakabatanidzwa ne polypropylene fiber ine simba rekudhonza re20-50 kN/m², Compressive modulus inodarika ye geogrid yechinyakare nekanopfuura katatu. Mukuyera chaiko kwezvikamu zvemota dzinotakura vanhu vakawanda, kugadzika kwe subgrade yakaiswa necomposite drainage network kunoderedzwa ne42%, uye kuwanda kwemigwagwa kunoderedzwa ne65%.

3, dhizaini yakabatanidzwa yemabasa akawanda

Kuburikidza ne geotextile (200 g/m²Standard) uye chimiro chakabatanidzwa che three-dimensional mesh core panguva imwe chete inoita mabasa matatu e "reverse filtration-drainage-reinforcement":

（1）Saizi yezvidimbu zvekubvisa zvinobudirira zvejira risina kurukwa repamusoro ＞0.075mm Zvidimbu zvevhu zve

（2）Nzvimbo yemesh inokurumidza kutumira mvura inoyerera kudzivirira mvura ye capillary kuti isakwire

（3）Mbabvu dzakasimba dzinowedzera kugona kwekutakura hwaro uye dzinoderedza kuchinjika kwepasi pevhu

4, Kuchinjika kwezvakatipoteredza uye kugara kwenguva refu

Kudzivirira acid nealkali kwezvinhu izvi kunosvika pH 1-14, At-70 ℃ Kusvika 120 ℃ Kudzivirira tembiricha kunochengetedza mashandiro akagadzikana. Mushure memaawa 5000 ekuyedzwa kweUV nekukurumidza kwekukwegura, mwero wekuchengetedza simba ＞85%, Hupenyu hwebasa hunogona kusvika makore anopfuura makumi mashanu.

Zvinogumira pakushandiswa kwenetwork yemvura inosanganiswa

1, Kusakwana kwekupomba

Ukobvu hwepakati pemambure hunowanzova 5-8 mm, Hunoboorwa zviri nyore pamusoro pechigadziko chine matombo akapinza.

2, Kukwanisa kuchenesa mvura kushoma

Kana mvura ichiyerera nekukurumidza (kumhanya ＞0.5m/s）， Kune zvinhu zvakasimba zvakasungirirwa (SS） Kushanda kwekubata mvura i30-40% chete, uye inofanira kushandiswa nematangi e sedimentation kana mafirita mumapurojekiti ekuchenesa tsvina.

3, zvinodiwa zvetekinoroji yekuvaka yakasimba

（1）Kusimba kwepasi pendege kunofanira kudzorwa ≤15mm/m

（2）Kuda upamhi hwemakumbo 50-100 mm， Tora michina yekuwedera inopisa inonyunguduka

（3）Tembiricha yemhepo inofanira kuva-5 ℃ Kusvika 40 ℃ Pakati, mamiriro ekunze akaipisisa anogona kukonzera kuchinjika kwezvinhu zviri nyore

4, mutengo wekudyara wekutanga wakakwira

Kana tichienzanisa nejecha nejecha rekare, mutengo wezvinhu unowedzera neinenge 30%, asi mutengo wehupenyu hwese unoderedzwa ne40% (kuderedza nguva yekugadzirisa uye chiyero chekugadzirisa hwaro).

Chimwe. Chikumbiro cheinjiniya

1. Chirongwa chekugadzirisa migwagwa yemuguta

Muchivakwa chemugwagwa weasphalt, kuisa network yemvura yakasanganiswa pakati pechikamu chemacadam chakarongwa nechikamu chepasi pevhu kunogona kupfupisa nzira yemvura kusvika pakukora kwechikamu chepasi uye kuvandudza kushanda zvakanaka kwemvura.

2, Sistimu yekubvisa tsvina muvhu

Tora "network yekudhonza mvura yakasanganiswa" + HDPE Impervious membrane "chimiro chakabatana:

（1）Nzira dzekubatanidza mvura dzinoshandisa nzira yekubvisa mvura, kuyerera kwemvura ≤1×10⁻⁴cm/s

（2）2mm Gobvu HDPE Membrane inopa dziviriro mbiri inodzivirira kubuda kwemvura

3. Chirongwa chekuvaka guta reSponge

Kuisa mvura munzvimbo dzine mativi matatu uye nzvimbo dzakasvibira, zvichibatsirana nePP. Kushandiswa kwematangi emvura kunogona kuderedza mvura inoyerera kubva pa0.6 kusvika pa0.3 uye kuderedza kuzara kwemvura mumaguta.
