Izinzuzo kanye nokungalungi kwamanethiwekhi okudonsa amanzi ahlanganisiwe

Inethiwekhi yokudonsa amanzi ehlanganisiwe iyinto evame ukusetshenziswa kumaphrojekthi emigwaqo, ezindaweni zokulahla udoti, ekuthuthukisweni kwesikhala esingaphansi komhlaba kanye neminye imisebenzi. Ngakho-ke, yiziphi izinzuzo kanye nokungalungi kwayo?

一. Izinzuzo eziyinhloko zenethiwekhi yokudonsa amanzi ehlanganisiwe

1, ukusebenza kahle kakhulu kokukhipha amanzi

Inethi yokukhipha amanzi ehlanganisiwe isebenzisa isakhiwo se-mesh core esinezinhlangothi ezintathu (ubukhulu buvame ukuba ngu-5-8 mm）， Ubambo oluqondile oluphakathi lwakha isiteshi sokukhipha amanzi esiqhubekayo ngokusekelwa okuthambekele, futhi ukusebenza kahle kokukhipha amanzi kuphindwe ka-5-8 kunokwendlalelo yendabuko yamatshe. Uhlelo lwayo lokulungisa ama-pore lungamelana nemithwalo ephezulu (3000 kPa Umthwalo ocindezelayo) lugcina ukuhanjiswa kwamanzi okuzinzile, futhi ukufuduka ngesikhathi seyunithi kungafinyelela ku-0.3 m³/m²，Ifaneleka kakhulu ezimweni ezikhethekile ze-geological njengezindawo zomhlabathi eziqandisiwe kanye nokwelashwa kwesisekelo esithambile.

2, Amandla aphezulu kanye nokumelana nokuguquguquka

Yakhiwe nge-polyethylene enobuningi obukhulu (i-HDPE) I-mesh core ehlanganiswe ne-polypropylene fiber inamandla okubamba amabili angu-20-50 kN/m², I-modulus yokucindezela idlula eye-geogrid yendabuko ngokuphindwe kathathu. Ekulinganisweni kwangempela kwezingxenye zethrafikhi ezisindayo, ukuhlaliswa kwe-subgrade ebekwe ngenethiwekhi yokudonsa amanzi ehlanganisiwe kuncishisiwe ngo-42%, kanti ukwanda kwemifantu yendlela kuncishisiwe ngo-65%.

3, umklamo ohlanganisiwe wemisebenzi eminingi

Ngokusebenzisa i-geotextile (200 g/m²Standard) kanye nesakhiwo esihlanganisiwe se-three-dimensional mesh core ngesikhathi esisodwa kufeza imisebenzi emithathu "yokuvuselela ukuhlunga okuphambene nokukhipha amanzi":

（1）Usayizi wezinhlayiya eziphumelelayo zokubanjwa kwendwangu engalukiwe engqimbeni engenhla ＞0.075mm Izinhlayiya zomhlabathi

（2）I-mesh core ithumela ngokushesha amanzi angena emanzini ukuze ivimbele amanzi e-capillary ukuthi angakhuphuki

（3）Izimbambo eziqinile zithuthukisa amandla okuthwala isisekelo futhi zinciphise ukuguquguquka kwe-subgrade

4, Ukuzivumelanisa nezimo kwemvelo kanye nokuqina kwayo

Ububanzi bokumelana ne-asidi ne-alkali yale nto bufika ku-pH 1-14, At-70 ℃ To 120 ℃ Ububanzi bokushisa bugcina ukusebenza kuzinzile. Ngemva kwamahora angu-5000 okuhlolwa kokuguga okusheshayo kwe-UV, izinga lokugcina amandla ＞85%, Impilo yesevisi ingafinyelela eminyakeni engaphezu kwengu-50.

Futhi. Imikhawulo yokusetshenziswa kwenethiwekhi yokudonsa amanzi ehlanganisiwe

1, Ukumelana nokubhoboza okunganele

Ubukhulu be-mesh core ngokuvamile bungu-5-8 mm, Buhlatshwa kalula endaweni eyisisekelo equkethe itshe elibukhali.

2, Umthamo wokuhlanza amanzi olinganiselwe

Ngaphansi kwezimo zokugeleza kwamanzi ngesivinini esikhulu (isivinini ＞0.5m/s）， Kwezinto eziqinile ezilengisiwe (SS） Ukusebenza kahle kokuvinjelwa kungu-30-40% kuphela, futhi kufanele kusetshenziswe namathangi okuthuthwa kwendle noma izendlalelo zokuhlunga kumaphrojekthi okwelapha indle.

3, Izidingo zobuchwepheshe bokwakha eziqinile

（1） Ukuthamba kwesisekelo kufanele kulawulwe ≤15mm/m

（2）Isidingo sobubanzi be-Lap 50-100 mm， Sebenzisa imishini ekhethekile yokushisela eshisayo

（3）Izinga lokushisa elizungezile kumele libe ngu-5 ℃ Kuze kube ngu-40 ℃ Phakathi, isimo sezulu esibi kakhulu singaholela kalula ekuguqukeni kwezinto ezibonakalayo

4. Izindleko zokutshalwa kwezimali zokuqala eziphakeme

Uma kuqhathaniswa nesendlalelo sokukhipha amanzi sesihlabathi namatshe ayigugu esivamile, izindleko zezinto zokwakha zikhuphuka cishe ngo-30%, kodwa izindleko zomjikelezo wokuphila wonke zincishiswa ngo-40% (kunciphisa imvamisa yokulungisa kanye nesilinganiso sokulungisa isisekelo).

Enye. Isicelo sobunjiniyela

1. Uhlelo lokwenza ngcono umgwaqo kamasipala

Esakhiweni se-asphalt pavement, ukubeka inethiwekhi yokukhipha amanzi ehlanganisiwe phakathi kwesendlalelo se-macadam esilinganisiwe kanye ne-subgrade kungafinyeza indlela yokukhipha amanzi iye ekujiyeni kwesendlalelo sesisekelo futhi kuthuthukise ukusebenza kahle kokukhipha amanzi.

2, uhlelo lokuvimbela ukuvuza kwamanzi endaweni yokulahla imfucuza

Yamukela "inethiwekhi yokudonsa amanzi ehlanganisiwe" + i-HDPE Impervious membrane "isakhiwo esihlanganisiwe:

（1）Iziqondiso zenethiwekhi yokudonsa amanzi, i-leachate, i-permeability coefficient ≤1×10⁻⁴cm/s

（2）2mm Ulwelwesi lwe-HDPE olujiyile luhlinzeka ngokuvikelwa okuphindwe kabili kokuvimbela ukuvuza kwamanzi

3, iphrojekthi yokwakha idolobha laseSponge

Ukubeka izihlahla ezinamazinga amathathu ezivandeni zemvula kanye nezindawo eziluhlaza ezicwile, kubambisene ne-PP Ukusetshenziswa kwamachibi okugcina amanzi kunganciphisa i-coefficient yokugeleza kwamanzi kusuka ku-0.6 kuya ku-0.3 futhi kunciphise ukugcwala kwamanzi emadolobheni.
