Mumapurojekiti ekudzora kudonha kwemvura—akadai seaya anosanganisira zvivakwa zvepasi pevhu, madhamu ekugadzira, uye nzvimbo dzekurasira marara—dambudziko rinogara riripo rekudonha kwemvura rinogona kugadziriswa sei zvinobudirira uye zvinogara kwenguva refu? Semugadziri ane hunyanzvi mumunda we geosynthetics, Shandong Hongyue Environmental Engineering Co., Ltd. (inozivikanwa se "Hongyue Environmental") yakashandisa hunyanzvi hwayo hwakakura muGeosynthetic Clay Liners (GCLs) kugadzira nzira yekuvaka yakasimba uye yakajairika yesainzi. Kuburikidza nematanho mana makuru—"kugadzirira pasi pevhu, kuisa kwesainzi, kupindirana kwakaringana, uye kuzadza mvura nenguva"—iyi nzira inoshandisa zvizere mabhenefiti akasiyana eGCLs, kunyanya kugona kwavo "kuzvimba kana vasangana nemvura uye kuzviporesa," nokudaro vachigadzira chipingamupinyi chisingapindiki chemvura chemabasa akasiyana-siyana einjiniya.
Danho Rokutanga: Kugadzirira Kwakasimba Pasi pevhu—Kuisa Nheyo Yakatsetseka Uye Yakasimba
Hunhu hwesubgrade hunotarisa zvakananga kushanda kwekuisa GCL. Chikwata chehunyanzvi cheHongyue Environmental chinosimbisa kuti pamusoro pesubgrade panofanira kugadziriswa zvakasimba pasati pavakwa. Kutanga, subgrade inofanira kuomeswa uye kuenzana; kunyanya, chiyero chekutsandarara (chinotsanangurwa sechiyero chekudzika kwakanyanya kwechero kudzika kusvika padhayamita yaro shoma) hachifanirwe kudarika 1:6, uye kushanduka kwese kunofanirwa kuitwa zvishoma nezvishoma, zvichirambidza kuvapo kwezvinhu zvakapinza zvakaita semakona ekurudyi. Chechipiri, pamusoro pesubgrade panofanira kuchengetwa kwakachena, nekubviswa kwakazara kwetsvina yese yakapinza—kusanganisira midzi yehuswa, dhayamita yakakura kupfuura 10 mm, uye zvidimbu zvezvidhinha—kudzivirira jira rekunze rakarukwa reGCL kuti risaboorwe panguva yekuisa. Uyezve, nepo GCL dzichigona kuiswa pamusoro pesubgrade dzakanyorova, kuunganidzwa kwemvura yakamira pamusoro payo kunorambidzwa zvachose; mune zviitiko apo mvura inoyerera isingadzoreki inosangana, matanho ekutsauka kwenguva pfupi anofanirwa kuitwa pachine nguva kuti ive nechokwadi chekuti nzvimbo yebasa inoramba iri mumamiriro akanaka.
Danho Rechipiri: Kuisa Kwakajairwa uye Kutsigira—Kuve nechokwadi chekuti Yakwana Zvakasimba Uye Zvakachengeteka
Munguva yekuisa, Hongyue Environmental inokurudzira kucheka maGCL nemazvo zvichienderana nehukuru hweprojekiti; ma liner anogona kuiswa akachinjika kana kuti akarebesa. Munguva yekuvaka, GCL inopetwa yakatsetseka pamusoro pe subgrade yakagadzirwa, inowanzoiswa nejira rakarukwa rakatarisana pasi uye geotextile isina kurukwa yakatarisa kumusoro. Kuti ive nechokwadi chekuti GCL ne subgrade zvinosangana, mapini e anchor nema washers akakosha anofanirwa kushandiswa pakusunga zvakasimba; pamusoro pezvo, mipendero ye liner inofanira kuremedzwa nemasandbags kudzivirira kusuduruka kunokonzerwa nemhepo. Nyanzvi dzehunyanzvi dzinosimbisa kuti kungwarira kwakanyanya kunofanira kuitwa panguva yekuisa. Zvinorambidzwa zvachose kuti michina inorema ifambe zvakananga pamusoro pegumbeze. Vashandi vanofamba pamusoro pechinhu ichi vanofanira kupfeka shangu dzakatsetseka kudzivirira zvinhu zvakapinza kubva pakuboora membrane yemukati (kana iri magumbeze asina mvura ane membrane-laminated) kana kukuvadza geotextile yekunze, chero ipi zvayo inogona kukanganisa kupararira kwakafanana kwebentonite.

Kurapa majoini ndicho chinhu chakakosha chinoona kubudirira kana kukundikana kwehurongwa hwese husingapindi mvura. Zvinodiwa zveHongyue Environmental pakuvaka zvinorayira kuti upamhi hwemagumbeze asingapindi mvura ari pedyo hunofanira kuchengetedzwa huri pakati pe25 cm kusvika 30 cm. Mukati menzvimbo inopindirana, upfu hwakasarudzika hwebentonite (kana bentonite paste)—hunopihwa nekambani—hunofanira kuiswa zvakaenzana. Mwero wekushandiswa unowanzo dzorwa pa0.4 kg/m² kuitira kuti, kana yasangana nemvura, joini iite jira risingapindi mvura rinogara, rakakora, rakaita sejeri. Kuti isimbise zvakanyanya kupindirana, kuiswa kweupfu kunogona kuwedzerwa netepi inodzivirira mvura, ichiva nechokwadi chekuti zvese zvakachengeteka uye zvichigadzira chipingamupinyi chisina musono, chinoramba chichipindirana.
Danho rechina: Kuzadza Zvimedu Nenguva Yakakodzera—Kupa Dziviriro Yenguva Refu
Kana magumbeze asingapindi mvura aiswa, kuvaka magumbeze ekudzivirira kana kuti kuzadza magumbeze kunofanira kutanga nekukurumidza. Izvi zvinodzivirira magumbeze kuti asaome uye asashande zvakanaka nekuda kwekunge abatwa nemhepo kwenguva refu, kana kuzvimba nguva isati yakwana kana mvura yanaya. Hongyue Environmental inonyanya kusimbisa zvinodiwa zvemhando yepamusoro yevhu rekuzadza magumbeze: ivhu rinofanira kuvharwa kuti zvinhu zvakaoma—zvakaita sejecha kana zvidhinha—zvine saizi inodarika 10 mm. Panguva yekuvaka, ivhu rakachena kana jecha rakatsetseka rinofanira kushandiswa pakuzadza magumbeze nekudzvanya; ukobvu hwegumbeze rega rega hunofanira kudzorwa mukati me30 cm kusvika 50 cm, uye huwandu hwekudzvanya hunofanira kusvika 85%. Maitiro aya haangodziviriri magumbeze asingapindi mvura kubva mukukuvadzwa kwekunze asiwo anoshandisa kumanikidzwa kunoitwa nehuremu hwevhu kuti awedzere kugadzikana kwegumbeze risingapindi mvura.
Vachishandisa nzira iyi yekuvaka ine matanho mana, magumbeze eShandong Hongyue Environmental ebentonite asingapindi mvura anokwanisa kuratidza zvakanakira zvikuru: kuramba simba rakawanda remvura inoyerera (inodarika 1.0 MPa), kugona kuzviporesa kwakasimba (kunokwanisa kugadzirisa mitswe inosvika 2 mm), pamwe nekuramba kukwegura zvakanaka uye hunhu husingakuvadzi nharaunda. Kubva pakugadzira zvinhu kusvika pakutungamira kwehunyanzvi panzvimbo, Hongyue Environmental Protection yakazvipira zvakasimba kupa vatengi mhinduro dzakabatana dzinodzivirira kunyura kwemvura, ichishandisa hunyanzvi hwehunyanzvi uye maitiro akaomarara kuona kuti chirongwa chega chega chinoramba chisina mvura zvachose.
