Iingenelo kunye nokungalungi kwenethiwekhi yokukhupha amanzi edibeneyo

Inethiwekhi yokukhupha amanzi edibeneyo sisixhobo esisetyenziswa kakhulu kwiiprojekthi zendlela, kwiindawo zokulahla inkunkuma, uphuhliso lwesithuba esingaphantsi komhlaba kunye nezinye iiprojekthi. Ngoko ke, zithini izibonelelo kunye neengxaki zayo?

一. Iingenelo eziphambili zenethiwekhi yokukhupha amanzi edibeneyo

1, ukusebenza kakuhle kokukhupha amanzi

Inethi yokukhupha amanzi edibeneyo isebenzisa isakhiwo se-mesh core esinemilinganiselo emithathu (ubukhulu buhlala buyi-5-8 mm）， Umbindi othe nkqo ophakathi wenza umjelo wokukhupha amanzi oqhubekayo ngenkxaso ethambekileyo, kwaye ukusebenza kakuhle kokukhupha amanzi kuphindwe ka-5-8 kunomaleko wegrabile wendabuko. Inkqubo yayo yokugcinwa kweembobo inokumelana nemithwalo ephezulu (3000 kPa Umthwalo oxinzelelweyo) igcina ukuhanjiswa kwamanzi okuzinzileyo, kwaye ukufuduka ngexesha ngalinye kunokufikelela kwi-0.3 m³/m²，Ifanelekile ngokukodwa kwiimeko ezikhethekileyo zejoloji ezifana neendawo zomhlaba ezikhenkcezisiweyo kunye nonyango lwesiseko esithambileyo.

2, amandla aphezulu kunye nokumelana nokuguquguquka

Yenziwe nge-polyethylene enoxinano oluphezulu (HDPE) I-mesh core edityaniswe ne-polypropylene fiber inamandla okutyhala amabini angama-20-50 kN/m², I-compressive modulus idlula leyo ye-geogrid yendabuko ngaphezu kwamaxesha ama-3. Kwimilinganiselo yokwenyani yamacandelo ezithuthi ezinzima, ukuhlaliswa kwe-subgrade ebekwe ngenethiwekhi yokukhupha amanzi edibeneyo kuncitshiswa ngama-42%, kwaye ukuxhaphaka kwemifantu yendlela kuncitshiswa ngama-65%.

3, uyilo oludibeneyo olunemisebenzi emininzi

Ngokusebenzisa i-geotextile (200 g/m²Standard) kunye nesakhiwo esidibeneyo se-three-dimensional mesh core ngaxeshanye senza imisebenzi emithathu "yokuhluza-ukubuyisela amanzi-ukubuyisela umva":

（1）Ubungakanani obusebenzayo bokuthintelwa kwamasuntswana belaphu elingalukwanga elingaphezulu ＞0.075mm Amasuntswana omhlaba

（2）Isiseko se-mesh sithumela ngokukhawuleza amanzi angena emanzini ukuthintela amanzi e-capillary ukuba anganyuki

（3）Iimbambo eziqinileyo ziphucula amandla okuthwala isiseko kwaye zinciphise ukuguquguquka kwe-subgrade

4, ukuziqhelanisa nokusingqongileyo kunye nokuqina

Uluhlu lokumelana ne-asidi kunye ne-alkali lwezixhobo lufikelela kwi-pH 1-14, At-70 ℃ Ukuya kwi-120 ℃ Uluhlu lobushushu lugcina ukusebenza kuzinzile. Emva kweeyure ezingama-5000 zovavanyo lokwaluphala olukhawulezileyo lwe-UV, izinga lokugcina amandla ＞85%, Ubomi benkonzo bunokufikelela kwiminyaka engaphezu kwama-50.

Oku kuthetha. Imida yokusetyenziswa kwenethiwekhi yokukhupha amanzi edibeneyo

1, Ukumelana nokubhoboza okunganelanga

Ubukhulu be-mesh core ngokubanzi yi-5-8 mm, Ihlatywa lula kumphezulu osisiseko oqulethe ilitye elibukhali.

2, Umthamo wokucoca amanzi olinganiselweyo

Phantsi kweemeko zokuhamba kwamanzi ngesantya esiphezulu (isantya ＞0.5m/s）， Kwizinto eziqinileyo ezixhonyiweyo (SS） Ukusebenza kakuhle kokuthintelwa kwamanzi yi-30-40% kuphela, kwaye kufuneka isetyenziswe neetanki zokuthuthwa kwamanzi okanye iileya zesihluzi kwiiprojekthi zokucocwa kwamanzi amdaka.

3, iimfuno zobuchwepheshe bokwakha ezingqongqo

（1）Ubucaba beplane esisiseko kufuneka bulawulwe ≤15mm/m

（2）Imfuneko yobubanzi beLep 50-100 mm， Sebenzisa izixhobo ezikhethekileyo zokuwelda ezishushu ezinyibilikisiweyo

（3）Ubushushu obuphakathi kufuneka bube-5 ℃ Ukuya kuma-40 ℃ Phakathi, imozulu egqithisileyo inokukhokelela ngokulula ekuguqukeni kwezinto

4, iindleko zokuqala eziphezulu zotyalo-mali

Xa kuthelekiswa nomaleko wokukhupha amanzi wesanti kunye negrabile wendabuko, iindleko zezinto zinyuka malunga ne-30%, kodwa iindleko zomjikelo wobomi bonke zincitshiswa nge-40% (ukunciphisa amaxesha okugcinwa kunye nesantya sokulungiswa kwesiseko).

Enye. Isicelo sobunjineli

1. Inkqubo yokwenza ngcono indlela kamasipala

Kwisakhiwo sendlela ye-asphalt, ukubeka inethiwekhi yokukhupha amanzi edibeneyo phakathi komaleko we-macadam olinganisiweyo kunye ne-subgrade kunokunciphisa indlela yokukhupha amanzi ukuya kubukhulu bomaleko osisiseko kwaye kuphucule ukusebenza kakuhle kokukhupha amanzi.

2, inkqubo yokulahla inkunkuma engangenisi amanzi

Yamkela "inethiwekhi yokukhupha amanzi edityanisiweyo" + i-HDPE Impervious membrane "isakhiwo esidibeneyo:

（1）Izikhokelo zenethiwekhi yokukhupha amanzi amdaka, i-permeability coefficient ≤1×10⁻⁴cm/s

（2）2mm I-HDPE Membrane Engqindilili inika ukhuseleko oluphindwe kabini oluchasene nokuphuma kwamanzi

3, iprojekthi yokwakha isixeko saseSponge

Ukubeka igadi yemvula kwiindawo eziluhlaza ezitshonileyo, kusebenzisana nePP. Ukusetyenziswa kwamachibi okugcina amanzi anomlinganiselo ofanayo kunokunciphisa i-flowoff coefficient ukusuka kwi-0.6 ukuya kwi-0.3 kwaye kunciphise ukugcwala kwamanzi ezidolophini.
