Product Details
Fiberglass geogrid yakanakisa geosynthetic zvinhu zvinoshandiswa kusimbaradza mugwagwa, yekare mugwagwa kusimbiswa, kusimbisa mugwagwa base uye ivhu rakapfava. Fiberglass geogrid chigadzirwa chakaomesesa chakagadzirwa nepamusoro-soro alkali-isina fiberglass kuburikidza nepasi rose advanced warp knitting process uye yakaputirwa nekurapwa kwepamusoro. Iine simba rakanyanya kusimba uye yakaderera kureba mune ese ari maviri warp uye weft nzira, uye ine yakanakisa zvivakwa zvekupisa tembiricha, kutonhora kushoma, kuramba kuchembera, kusaita ngura, etc. Inoshandiswa zvakanyanya muasphalt pavement, simende pavement nekusimbisa bhedhi. njanji mugwagwa, kudzivirira kutsetseka kwedhamu, nhandare yendege, kutonga jecha uye mamwe mapurojekiti einjiniya.
Chinhu chikuru chefiberglass ndeichi: silicon oxide, is inorganic materials, maitiro ayo emuviri nemakemikari akanyanya kugadzikana, uye ane modulus yakakwirira, kupfeka kusagadzikana uye kutonhora kwakanyanya, hakuna nguva refu inokambaira; kugadzikana kwakanaka kwekushisa; mesh chimiro kuitira kuti aggregate yakamisikidzwa kukiya uye muganho; kunatsiridza simba rekutakura-kutakura kweasphalt musanganiswa. Nekuti iyo nzvimbo yakashongedzwa neyakagadziridzwa asphalt, ine maviri emusanganiswa zvimiro, zvese zvakanakisa zvimiro zvefiberglass uye kuenderana neasphalt musanganiswa, izvo zvinovandudza abrasion kuramba uye shear kuramba kwegeogrid.
Zvimiro zvefiberglass geogrid zvigadzirwa
Chigadzirwa chacho chine simba rakawanda, kureba kwakadzika, kupikisa kwekushisa kwepamusoro, modulus yakakwira, huremu huremu, kusimba kwakanaka, kusagadzikana kwemarara, hupenyu hurefu, etc. kuchengetedzwa kwemateru, mugwagwa uye bhiriji pavement yekuvandudza kurapwa uye dzimwe minda yeinjiniya, iyo inogona kupa kukwidziridzwa kwegwagwa, kusimbiswa, kudzivirira pavement rutting kupera simba, kupisa. uye kutonhora kwekuwedzera kutsemuka uye kufungidzira kutsemuka pazasi, uye inogona Kupararira, kurebesa hupenyu hwesevhisi yegwagwa, yakakwira yakasimba simba yakaderera kureba, hapana kukweva kwenguva refu, kugadzikana kwemuviri uye kemikari kugadzikana, kugadzikana kwakanaka kwemafuta, kuneta kuputika kuramba, tembiricha yakanyanya kutsvedza. , yakaderera tembiricha shrinkage cracking resistance, kunonoka kuderedzwa kwekuratidzira kutsemuka.
Fiberglass geogrid kuvaka maitiro
(1) Chekutanga, nyatso buritsa mutsetse wemutsetse weroadbed, kuitira kuti uve nechokwadi chekufara kweroadbed, divi rega rega rinowedzerwa ne 0.5m, kuomeswa kwevhu rakanaka repasi rekuenzanisa mushure mekushandisa 25T vibratory roller static pressure. kaviri, uye ipapo 50T kuvhunduka kudzvinyirirwa kane, nzvimbo isina kuenzana ine bhuku rekuenzanisa.
(2) Kuisa 0.3m gobvu yepakati (yakakora) jecha, bhuku rine mechanical leveling, 25T vibration roller static pressure kaviri.
(3) kuisa geogrid, geogrid kuisa pasi pasi kunofanirwa kuve kwakati sandara, kutetepa, kazhinji kunofanirwa kuve kwakatsetseka, kwakatwasuka, pasina kupindirana, hakuna curl, kink, maviri akatarisana geogrid anoda kupeta 0.2m, uye pamwe neroadbed lateral geogrid lap chikamu chimwe nechimwe. 1m ine No. 8 waya yekubatanidza interpolation, uye mumagridi akaiswa, yega 1.5-2m ine U-zvipikiri zvakagadziriswa pasi.
(4) chikamu chekutanga chegeogrid paved, chakatanga kuzadza chikamu chechipiri che 0.2m mukobvu mujecha (rakakomba), iyo nzira: jecha remotokari kunzvimbo yakaburutswa padivi pemugwagwa, uye ipapo shandisa bulldozer kusundira mberi. , kutanga 2 metres kumativi ese emugwagwa mushure mekuzadza 0.1m, iyo yekutanga layer ye geogrid yakapetwa kumusoro ndokuzadzwa ne 0.1m mukati (yakakora) jecha, rambidza mativi maviri kusvika pakati pekuzadza uye kufambira mberi, rambidza marudzi ese emuchina kana pasina Izvi zvinogona kuve nechokwadi chekuti geogrid yakati sandara, isina madhiramu uye wrinkles, uye mushure mechikamu chechipiri chepakati (yakaoma) jecha rakapetwa. , kuyerwa kwechiyero kunofanirwa kuitwa kudzivirira kusaenzana kwekuzadza ukobvu, uye iyo 25T vibratory roller inofanirwa kushandiswa kaviri mushure mekuyera kwakaringana.
(5) chikamu chechipiri che geogrid yekuvaka nzira ine yekutanga nzira imwe chete, uye pakupedzisira kuzadza 0.3m mu (yakakomba) jecha, ichizadza nzira yakafanana neyekutanga, ne 25T roller static pressure kaviri, kuitira kuti roadbed substrate reinforcement inopedzwa.
(6) muchikamu chechitatu che (yakaoma) jecha rakapwanyika, pamwe nemutsara wemugwagwa welongitudinal kumativi ose emutsetse wakaisa geogrid maviri, lap 0.16m, uye yakabatana nenzira imwechete, uye wozotanga mabasa ekuvaka kwepasi, kuisa geogrid. yekudzivirira kwemateru, imwe neimwe layer inofanirwa kuyerwa kunze kwemupendero wekuisa, divi rega rega kuti ive nechokwadi chekuti nzvimbo inogadzirisa geogrid yakavigwa mukati. mutsetse 0.10m.
(7) Pazvikamu zviviri zvose zvevhu rakazadzwa, kureva 0.8m muhukobvu, geogrid inofanira kuiswa kumativi ose panguva imwe chete, uye zvakadaro kusvikira yasvika pamusoro pepfudzi remugwagwa.
(8) mushure mekunge mugwagwa wazadzwa, kugadziriswa kwemateru panguva, uye kuchengetedzwa kwematombo akaoma pasi petsoka, chikamu chemugwagwa mukuwedzera kuwedzera 0.3m kune rumwe rutivi, uye kuchengetedza 1.5% yekunyura.
