Mambure ekudhonza mvura ane mativi matatu anoshandiswa zvakanyanya mumapurojekiti makuru. Saka, anofanira kubatanidzwa sei panguva yekuvaka?
1. Kugadziriswa kwenzira yekubatana
Pakuisa mambure emvura akagadzirwa nemativi matatu, gadzirisa divi remambure emvura kuti uve nechokwadi chekuti divi remambure emvura rakatarisa divi guru remugwagwa kana purojekiti. Kugadzirisa uku kunobvumira mambure emvura kuti arambe achishanda zvakanaka pakutakura mitoro, kugadzirisa nzira yemvura, uye kuvandudza kushanda zvakanaka kwemvura. Kana divi racho rikasagadziriswa zvakanaka, zvinogona kukonzera kusashanda zvakanaka kwemvura kana kuungana kwemvura munzvimbo, zvichikanganisa mhedzisiro yepurojekiti.
2. Kugumiswa kwezvinhu uye kupindirana
Mambure ekudhonza mvura ane mativi matatu anofanira kugumiswa, uye mageotextile ari padyo ne geonet cores anofanira kupindirana negwara remagadzirirwo echinhu. Kana uchipindirana, iva nechokwadi chekuti geotextile yakati sandara uye haina makwinya, uye kureba kwekubatanidza kunosangana nezvinodiwa zvekugadzira. Kazhinji, kureba kwekukwirirana kwenguva refu hakusi pasi pe15cm, uye kureba kwekukwirirana kwakachinjika kunodzorwa mukati me30-90cm. Kureba kusina kukwana kwekubatanidza kunogona kutungamira kusimba kusina kukwana pajoini, zvichikanganisa kugadzikana kwe drainage net; nepo kuwanda kwekubatanidza kunogona kuwedzera marara echinhu uye kuoma kwekuvaka.
3. Kushandisa zvinobatanidza
Mukugadzirisa majoini, kusarudzwa nekushandiswa kwezvinobatanidza zvakakosha zvikuru. Kazhinji, mabhurukwa epurasitiki machena kana eyero kana tambo dzepolymer zvinoshandiswa kubatanidza ma geonet cores emaroro e geotextile ari pedyo. Pakubatanidza, shandisa zvinobatanidza kuti uzvigadzire pane dzimwe nguva (senge 30cm kana 1m) pamwe chete nehurefu hweroro yezvinhu. Zvinobatanidza zvinofanira kunge zvine simba rakakwana uye kugara kwenguva refu kuti zvive nechokwadi chekuti majoini acho akasimba. Kana zvinobatanidza zvikashandiswa zvisina kunaka, majoini anogona kusunungura kana kudonha, zvichikanganisa mhedzisiro yekubuda kwemvura mumambure ekubvisa mvura.
4. Kugadziriswa kwema geotextiles anopindirana
Kana mambure emvura akagadzirwa nemativi matatu akaiswa pakati pehwaro, hwaro nepasi pevhu, ma geotextile anowirirana anofanira kugadziriswa. Nzira dzekugadzirisa dzinosanganisira kuchinjika kwe wedge, kuchinjika kwemusoro wakatsetseka kana kusona. Pakusanganisa, iva nechokwadi chekuti ma welds akatsvinda, akanaka uye haana kutsvedza uye kusvetuka; pakubatanidza, kusanganisa kwemusoro wakatsetseka kana kusona kwakajairika kunogona kushandiswa kusangana nezvinodiwa zvehurefu hwe stitch. Kugadzirisa kunogona kuwedzera simba nekugadzikana kwemajoini uye kudzivirira ma geotextile kuti asasuduruke kana kukuvara panguva yekurongedza ma fillers.
5. Kurapa kwakakosha kwenharaunda
Munzvimbo dzakakosha, dzakadai sepanenge paine matombo akaomarara pamusoro pegumbeze rematombo, kuitira kuti risaboore geomembrane isingadonhe, jecha rakatetepa rakasanganiswa (3-5cm gobvu) rinofanira kuparadzirwa uye kutenderedzwa pamusoro pegumbeze rematombo. Gumbeze rejecha rinofanira kufukidza zvakakwana pamusoro pegumbeze rematombo, uye hapafanirwe kuva nematombo ane saizi inopfuura 4mm mugumbeze rejecha. Pakuvaka munzvimbo dzinotonhora kana tembiricha yepamusoro, matanho akakodzera ekudzivirira anofanira kutorwa, akadai sekubatanidza kupisa nekugadzirisa nguva yekuvaka, kuve nechokwadi chekuti mhando yemajoini haakanganiswe nemamiriro ekunze.
Sezvatinoona kubva pane zviri pamusoro apa, kugadziriswa kwekubatana kwe "three-dimensional composite drainage net" chinhu chakakosha mukuvaka, icho chine chekuita zvakananga nemhedzisiro ye "drainage" uye kugadzikana kwese kwe "drainage net". Zvichitevera zvirevo zve "joint direction adjustment", "faction" uye "overlay", "connector" inoshandiswa, "overlay geotextile fixation" uye "special environment treatment" zvinogona kuve nechokwadi chekusimba nekugadzikana kwemajoin uye kuvandudza kushanda kwe "drainage" uye hupenyu hwebasa re "drainage net".
