Kwinjineli, ingxaki yokusila ihlale ibaluleke kakhulu. Inethiwekhi yokukhupha amanzi edibeneyo enemilinganiselo emithathu. Yinto yokukhupha amanzi esetyenziswa kakhulu kwiiprojekthi ezinkulu. Ngoko ke, ingaba ingathintela ukusila kunye nokuvaleka?
1. Uyilo olutsha lwesakhiwo
Inethiwekhi yokukhupha amanzi edityanisiweyo enamacala amathathu yenziwe yi-geotextile enamacala amabini kunye ne-geotextile enamacala amathathu. I-mesh core yenziwe nge-polyethylene enoxinano oluphezulu (HDPE) Inkqubo yokubumba enamacala amathathu yenza inethiwekhi yeembambo ezinqamlezayo, kwaye ukwahluka kwayo kubonakala kwezi zinto zimbini zilandelayo:
1, Inkqubo ye-Gradient Pore: isithuba sembambo ethe nkqo kwi-mesh core yi-10-20 mm, I-rib ethe tyaba phezulu kunye ne-rib esezantsi zenza itshaneli yokujika enemilinganiselo emithathu, ehambelana noyilo lwe-aperture gradient ye-geotextile (umaleko ongaphezulu yi-200 μm, Inqanaba elisezantsi yi-150 μm）， Ubungakanani be-particle obunokuthintelwa obungaphezulu kwe-0.3 mm ye-particle matter, i-Real Now "coarse filtration-fine filtration" ehleliweyo.
2、Uyilo oluchasene nokugxumeka: ubukhulu bembambo ye-mesh core ukuya kuthi ga kwi-4-8 mm， Kwi-2000 kPa Ngaphezulu kwe-90% yobukhulu bokuqala isenokugcinwa phantsi komthwalo, ukuze kuthintelwe ukuba i-geotextile ifakwe kwi-mesh ngenxa yokucinezelwa kwendawo. Ngokwedatha yobunjineli yendawo yokulahla inkunkuma, emva kweminyaka emi-5 yokusetyenziswa, umaleko wokukhupha amanzi usebenzisa le nto uya kuhambisa amanzi. Izinga lokuncitshiswa kwesantya yi-8% kuphela, eliphantsi kakhulu kune-35% yomaleko wegrabile wendabuko.
2. Iimpawu zezinto ezibonakalayo
1、Uzinzo lweKhemikhali: iHDPE I-mesh core ayimelani ne-asidi kunye nokugqwala kwe-alkali. Kwi-pH Kwindawo ebuthathaka ye-asidi kunye nesiseko esibuthathaka esinexabiso le-4-10, izinga lokugcina uzinzo lwesakhiwo sayo se-molecular lidlula i-95%. I-polyester edibeneyo I-Filament geotextile I-coating emelana ne-UV inokumelana nokuguga kwezinto okubangelwa yimitha ye-UV.
2、Indlela yokuzicoca: uburhabaxa bomphezulu we-mesh core Ra Ixabiso lilawulwa kwi-3.2-6.3 μm Ngaphakathi koluhlu, ayinakuqinisekisa kuphela ukusebenza kakuhle kokukhupha amanzi, kodwa ikwathintela ukunamathela kwe-biofilm okubangelwa bubuthambile obugqithisileyo.
3. Ukuziqhelanisa nobunjineli
1、Ukusetyenziswa kwenkunkuma: Kwindawo yokulahla inkunkuma enomthamo wokucubungula wemihla ngemihla weetoni ezingama-2,000, inethiwekhi yokukhupha inkunkuma edibeneyo enamacala amathathu kunye ne-HDPE. I-membrane yenza inkqubo edibeneyo yokulwa nokuphuma kwamanzi. Isiseko sayo se-mesh esinamacala amathathu sinokumelana ne-1500 ngosuku m³Umthwalo wempembelelo ye-leachate, kunye nomsebenzi we-backstop we-geotextile, unokufezekisa ukutyibilika. Ulwelo lukhutshwa kwicala elinye, nto leyo enokuthintela ukuvuza kwamanzi. Emva kweminyaka emi-3 yokusebenza, ixabiso lokuhla koxinzelelo lwe-drainage laminate yi-0.05 MPa kuphela, ngaphantsi komda woyilo we-0.2 MPa.
2、Isicelo sobunjineli beendlela: Kwindlela enkulu kwindawo yomhlaba oqandisiweyo kumantla eTshayina, ingasetyenziswa njengomaleko wokuhambisa amanzi angaphantsi komhlaba, onokunciphisa amanqanaba omhlaba ongaphantsi komhlaba nge-1.2% ngokuthintela ukunyuka kwamanzi e-capillary m。 Ukuqina kwesiseko sayo se-mesh yi-120 kN/m， Inganciphisa ukufuduka komaleko wesiseko odibeneyo kwaye inciphise ukwenzeka kwemifantu ebonakalisayo. Ukubeka esweni kubonisa ukuba ukwanda kweendlela ezisebenzisa obu buchwephesha kuncitshiswe ngama-67% xa kuthelekiswa nezifo zemveli ezingaphantsi komhlaba, kwaye ubomi benkonzo buyandiswa ukuya kwiminyaka engaphezu kwama-20.
3, Ukusetyenziswa kobunjineli beTunnel: Kwitonela kaloliwe edlula kwi-stratum etyebileyo emanzini, inethiwekhi yokukhupha amanzi edibeneyo enamacala amathathu kunye nekhethini ye-grouting zisetyenziswa kunye ukwenza inkqubo engangeni manzi "yokudibanisa ukukhupha amanzi kunye nokuvala". Umbindi wayo unombane we-hydraulic we-2.5 × 10⁻³m/s, Ipleyiti yokukhupha amanzi yendabuko engakumbi Phucula amaxesha ama-3, sebenzisana neLaphu le-geotechnical Umsebenzi wokucoca unokunciphisa umngcipheko wokuvaleka kwenkqubo yokukhupha amanzi etonela nge-90%.
4. Icebo lokugcina izinto zisemgangathweni
1, Ukubeka esweni izinto kwi-intanethi: Izinzwa zefayibha ye-optical zifakwe kwinethiwekhi yokukhupha amanzi ukuze zijonge iiparameter ezifana nokuqhuba kwe-hydraulic, uxinzelelo kunye noxinzelelo ngexesha langempela.
2. Ukucoca ijethi yamanzi enoxinzelelo oluphezulu: iindawo ezivaliweyo kwindawo ethile, sebenzisa i-20-30 MPa. Ijethi yamanzi enoxinzelelo oluphezulu yokuguqula i-redging ibe yi-directional dredging. Ulwakhiwo lwembambo ye-mesh core lunokuthwala uxinzelelo ngaphandle kokuguquka, kwaye izinga lokubuyisela i-hydraulic conductivity emva kokucoca lingaphezulu kwe-95%.
