Maitiro ekugadzira network yemvura inosanganiswa ine mativi matatu

Mambure ekudhonza mvura ane mativi matatu anoshandiswa zvakanyanya mumapurojekiti makuru. Saka, anogadzirwa sei?

1. Kusarudzwa kwezvinhu zvisina kucheneswa uye kurapwa kwekutanga

Chinhu chikuru chepurasitiki inoyerera mvura ine mativi matatu ipolyethylene ine huwandu hwakanyanya (HDPE). Zvinhu zveHDPE zvisati zvagadzirwa, zvinofanirwa kutariswa zvakanaka kuti zvive nechokwadi chekuti kuchena kwayo uye hunhu hwayo zvinosangana nezvinodiwa pakugadzirwa. Zvadaro zvinhu zvinogadziriswa nekuomesa, kupisa, nezvimwewo kubvisa hunyoro hwemukati netsvina kuti pave nehwaro hwakasimba hwekuumbwa kwemvura kunotevera.

2. Maitiro ekuumba extrusion

Kugadzira ma "extrusion molding" chinhu chakakosha pakugadzirwa kwema "three-dimensional composite drainage nets". Padanho rino, zvinhu zvakagadziriswa zveHDPE zvakagadziriswa kare zvinotumirwa kune nyanzvi ye "extruder", uye zvinhu zvakagadziriswa zvinonyungudutswa uye zvinoburitswa zvakaenzana kuburikidza nekupisa kwakanyanya uye munzvimbo ine kumanikidzwa kwakanyanya. Munguva ye "extrusion" inogadzirwa, musoro we "die" wakagadzirwa zvakanaka unoshandiswa kudzora nemazvo chimiro che "extrusion" uye saizi ye "mbabvu" kuti ugadzire chimiro che "three-rib" chine kona yakatarwa uye nzvimbo yakatarwa. Mbabvu idzi nhatu dzakarongwa nenzira yakati kuti dzigadzire chimiro che "three-dimensional space". Mbabvu yepakati yakasimba uye inogona kugadzira "drainage channel" inoshanda zvakanaka, nepo mbabvu dzakarongwa dzichiita basa rekutsigira, izvo zvinogona kudzivirira geotextile kuti isapinzwe mu "drainage channel", zvichiita kuti "drainage" ishande zvakanaka uye yakavimbika.

3. Kubatana kwe geotextile yakagadzirwa

Musoro we geonet une mativi matatu mushure mekuumbwa kwe extrusion unofanirwa kunge wakabatanidzwa ne geotextile inopindika mativi maviri. Maitiro aya anoda kuti namatidziro iiswe zvakaenzana pamusoro pe core ye net, uye geotextile inoiswa nemazvo, uye zviviri izvi zvinosanganiswa zvakasimba nekudzvanya kunopisa kana kubatana kwemakemikari. Musoro we drainage une mativi matatu haungogari nhaka mashandiro e drainage e geonet chete, asiwo unobatanidza mabasa ekudzivirira nekudzivirira e geotextile, zvichiita kuti pave ne "anti-filtration-drainage-protection".

4. Kuongorora kwemhando yepamusoro uye kurongedza kwechigadzirwa kwapera

Mambure ekudhonza mvura akagadzirwa nemativi matatu anofanira kuongororwa zvakanyanya, kusanganisira kuongororwa kwechitarisiko, kuyerwa kwehukuru, kuyedzwa kwekushanda uye zvimwe zvinongedzo kuti ive nechokwadi chekuti chigadzirwa chega chega chinosangana nezvinodiwa neindasitiri uye zvinodiwa nevatengi. Mushure mekupasa ongororo, mambure ekudhonza mvura anoputirwa zvakanaka kudzivirira kukuvara panguva yekufambisa nekuchengetedza. Kusarudzwa kwezvinhu zvekurongedza kunofanirwawo kutarisa pakuchengetedzwa kwezvakatipoteredza uye kugara kwenguva refu kuitira kuti chigadzirwa chigone kuendeswa kune vatengi zvakachengeteka uye zvisina dambudziko.
