Network yemvura inoshandiswa mukubatanidza mvura inoshandiswa zvakanyanya mumapurojekiti ekurasira marara, subgrade, tunnel mukati memadziro, njanji uye migwagwa mikuru. Saka, chii chaizvo chiri musimboti wayo?
1. Kuumbwa kwenzvimbo yekubatanidza mvura inoyerera
Mambure ekudhonza mvura akabatanidzwa imhando itsva yezvinhu zve geotechnical zvekudhonza mvura, iyo inoumbwa nepurasitiki ine mativi matatu uye geotextile bonding inopindika kumativi ese. Chimiro chayo chepakati chinosanganisira zvikamu zviviri zvepurasitiki ine mativi maviri uye geotextile.
1、Matanda epurasitiki: Matanda epurasitiki anowanzo gadzirwa nepolyethylene ine density yakakura (HDPE) Yakagadzirwa nezvinhu zvepolymer uye ine chimiro chemativi matatu. Chimiro ichi chinobvumira nzira dzakawanda dzemvura kuumbwa mukati memadziro emadziro, izvo zvinogona kutungamira kuyerera kwemvura nekukurumidza kuti ibude. Matanda epurasitiki ane simba rakawanda rekumanikidza uye kugara kwenguva refu, uye anogona kutsungirira mitoro inorema kwenguva refu pasina kuchinja.
2、Geotextile: Geotextile chinhu chinogadzirwa ne geosynthetic chine mvura inoyerera zvakanaka uye hunhu hwekusefa hunobva ku reverse. Chinonamirwa pamusoro pepakati pepurasitiki uye chinoshanda sesefa uye chinoburitsa mvura. Geotextile inogona kudzivirira tsvina kuti isapfuure nepakati, kudzivirira nzira dzekuburitsa mvura kuti dzisavharwe, uye zvakare kubvumira hunyoro kuti hupfuure zvakasununguka, zvichiita kuti nzira yekuburitsa mvura isavharwe.
2. Nheyo yekushanda kwenetwork yemvura inosanganiswa
Nheyo yekushanda kwenetwork yekudhonza mvura yakabatana inonyanya kuenderana nechimiro chayo chakasiyana uye hunhu hwayo hwepanyama. Kana mvura ichiyerera nepakati penetwork yekudhonza mvura yakabatana, inofamba nenzira dzinotevera:
1、Basa rekusefa: Kuyerera kwemvura kunotanga kupfuura nepa geotextile layer. Geotextile inoshandisa chimiro chayo chefiber chakanaka kudzivirira tsvina dzakadai sezvimedu zvevhu zviri kunze kwesystem yekudhonza mvura kuti ive nechokwadi chekuti nzira yekudhonza mvura haina kuvharwa.
2、Kubuda kwemvura: Kuyerera kwemvura yakaseferwa kunopinda mugwara rekubuda kwemvura repakati pepurasitiki. Nekuti pakati pepurasitiki ine chimiro chemativi matatu, kuyerera kwemvura kunogona kupararira nekukasira mukati mayo, uye pakupedzisira kunobuda nemunzira yekubuditsa mvura.
3、Kudzivirira kudzvanywa: Kana zvinhu zvaoma, simbi yepurasitiki yemumbure wekudhonza mvura inogona kuchengetedza chimiro chayo chakasimba uye haizokanganiswi kana kukuvara nekumanikidzwa. Nokudaro, network yekudhonza mvura inogona kuchengetedza kushanda kwemvura kwakasimba pasi pemamiriro akasiyana-siyana akaomarara enzvimbo.
3. Kushandiswa kwenetwork yemvura inosanganiswa
1、Kuvandudza kushanda zvakanaka kwemvura inoyerera: Chimiro chemhando nhatu uye kupindira zvakanaka kwemvura munetwork yemvura inoyerera zvinoita kuti ikwanise kutungamira kufamba kwemvura nekukurumidza uye kuvandudza kushanda zvakanaka kwemvura inoyerera. Inogona kuderedza kukuvara kwemvura inoungana kupurojekiti uye kuwedzera hupenyu hwebasa repurojekiti.
2. Kuvandudza kugadzikana kweprojekiti: Kuisa network yemvura yakasanganiswa kunogona kupararira nekuparadzira kushushikana muprojekiti uye kuwedzera kugadzikana kweprojekiti. Zvinogona kudzivirira matambudziko akadai sekugadzika kwenheyo uye kutsemuka kwenzira.
3、Deredzai mari yekugadzirisa: Mambure emvura akagadzirwa necomposite ane kugara kwenguva refu uye anodzivirira kumanikidzwa. Anogona kuchengetedza kushanda kwemvura kwakasimba panguva yekushandiswa kwenguva refu uye kuderedza nguva nemitengo yekugadzirisa.
