Network yekudhonza mvura inosanganiswa inoumbwa nezvinhu zvakasiyana-siyana

Mukuvaka kwemainjiniya emazuva ano nezvivakwa, masisitimu emvura akakosha zvikuru. Nzvimbo yemvura inoyerera ine mashandiro akanaka emvura, yakasimba uye inogara kwenguva refu, uye inowanzoshandiswa mumigwagwa, njanji, matunnel, mapurojekiti ekuchengetedza mvura uye nzvimbo dzekurasira marara. Saka, inoumbwa nezvinhu zvingani?

Mambure ekudhonza mvura akagadzirwa nezvinhu zvitatu zvikuru: purasitiki ine mesh core, geotextile inopindika mumvura uye jira rinonamira rinobatanidza zviviri izvi. Zvinhu zvitatu izvi zvinoshanda pamwe chete kuti zvive nechokwadi chekuti mvura inoyerera zvakanaka, yakasimba uye inogara kwenguva refu.

1, Plastic mesh core

（1）Matanda epurasitiki ndiwo anotsigira zvikuru mambure emvura akabatana, ayo akagadzirwa nepolyethylene ine simba guru (HDPE) Zvinhu zvepurasitiki zvine simba guru zvinogadzirwa nemaitiro ekugadzira ekuwedzera. Ine chimiro chakasarudzika chemativi matatu, icho chinoumbwa nembabvu dzakatwasuka nedzakatwasuka. Mbabvu idzi hadzina kuomarara chete uye dzinogona kugadzira nzira inoshanda yekudhonza mvura, asiwo dzinotsigirana kudzivirira geotextile kuti isapinzwe mugwara rekudhonza mvura, zvichiita kuti mambure ekudhonza mvura agare akasimba uye ashande zvakanaka.

（2）Kune magadzirirwo akasiyana-siyana esimbi yepurasitiki, kusanganisira simbi yesimbi ine mativi maviri uye simbi yesimbi ine mativi matatu. Simba resimbi rine mativi maviri rinoumbwa nesimbi yesimbi ine simbi ine mativi maviri, nepo simbi yesimbi ine mativi matatu kana kupfuura, iyo inoumba simbi yakaoma munzvimbo, ichipa simba remvura yakawanda uye simba rekumanikidza. Kunyanya network yesimbi ine mativi matatu, simbi yayo inogona kukurumidza kuburitsa mvura yepasi pevhu mumugwagwa uye kuvhara mvura ye capillary pasi pemutoro wakawanda, izvo zvinoita basa rekuparadzanisa uye kusimbisa hwaro.

2, geotextile inopindika mumvura

（1）Geotextile inopindika mumvura chimwe chikamu chakakosha checomposite drainage net, iyo inowanzo batanidzwa nemativi ese kana rimwe divi repurasitiki mesh core kuburikidza nekupisa. Geotextile inopindika mumvura yakagadzirwa nejeotextile isina kurohwa yakaboorwa netsono, iyo ine simba rakanaka kwazvo rekupinda kwemvura uye inodzivirira kusefa. Kugona kwayo kudzivirira zvidimbu zvevhu netsvina kuti zvisapinde mugwara remvura, inobvumirawo hunyoro kuti hupfuure zvakasununguka, zvichiita kuti system yemvura isavharwe.

（2）Kusarudzwa kwegeotextile inopindika mumvura kune simba guru pakushanda kwecomposite drainage net. Geotextile yemhando yepamusoro inopindika mumvura haina kungova nehukuru hwakanaka hwemaburi, inopindika mumvura uye inopindika, asiwo ine simba rekuboorwa kwepamusoro, simba rekubvarura trapezoidal uye simba rekusunga, kuitira kuti ive nechokwadi chekuti inogona kuramba simba rekunze uye kuparadzwa kwezvakatipoteredza mukushandiswa kwenguva refu.

3, namira rukoko

（1）Chikamu chinonamira ndicho chinhu chakakosha pakubatanidza core yepurasitiki negeotextile inopindika mumvura. Chakagadzirwa nezvinhu zvakakosha zvethermoplastic. Kuburikidza nemaitiro ekubatanidza anopisa, chikamu chinonamira chinogona kusanganisa zvakasimba core yepurasitiki negeotextile inopindika mumvura kuti chigadzire mambure emvura akabatanidzwa ane chimiro chakabatana. Chimiro ichi hachingovimbisi chete kugadzikana uye kugara kwenguva refu kwenet yekudonhedza mvura, asiwo chinoita kuti kuiswa kwayo nekuiswa kwayo zvive nyore uye nekukurumidza.

（2）Kushanda kwechikamu chinonamira kune simba guru pakushanda zvakanaka kwemuchina wekudhonza mvura uye kugona kudzivirira kukwegura kwemuchina wekudhonza mvura. Chikamu chinonamira chemhando yepamusoro chinogona kuona kuti muchina wekudhonza mvura hauzoparare kana kudonha kana uchishandiswa kwenguva refu, uye chinogona kuona kuti nzira yekudhonza mvura inoramba iripo uye yakasimba.

Sezvatinoona kubva pamusoro apa, mambure emvura akagadzirwa nezvinhu zvitatu: purasitiki ine mesh core, geotextile inopindika mumvura uye glue layer. Zvinhu izvi zvinoshanda pamwe chete kuti zvive nechokwadi chekuti mambure emvura anoshandiswa zvakanaka, akasimba uye anogara kwenguva refu.
