Hongyue faibha pfupi ine needled geotextile yakaboorwa
Tsananguro pfupi:
Geotextile yakagadzirwa newarp-knitted rudzi rutsva rwezvinhu zve geomaterials zvinoshanda zvakawanda, zvinonyanya kugadzirwa negirazi fiber (kana synthetic fiber) sechinhu chekusimbisa, nekubatanidza ne staple fiber needled non-woven fabric. Chinhu chikuru chayo ndechekuti nzvimbo yekuyambuka warp ne weft haina kukotama, uye imwe neimwe iri mumamiriro akatwasuka. Chimiro ichi chinoita kuti geotextile yakagadzirwa newarp yakarukwa ive nesimba rakasimba rekudhonza uye yakaderera kureba.
Tsananguro yeZvigadzirwa
Geotextile yeshinda pfupi ine needled punched yakagadzirwa neShandong Hongyue Environmental Protection Engineering Co., Ltd. imhando yezvinhu zvisina kurukwa zvakagadzirwa ne staple fiber ne tekinoroji yekuruka, iyo inoshandiswa zvakanyanya muinjiniya yezvivakwa, kuchengetedzwa kwezvakatipoteredza, kurima nedzimwe nzvimbo dzezvinhu zve geosynthetic. Kana ichienzaniswa ne geotextile yakarukwa neshinda yechinyakare isina kurukwa, geotextile yeshinda pfupi ine needled punched punched ine hunhu huri nani hwemakanika uye inochinjika.
Chinhu
1. Mesh yacho haivharike zviri nyore. Maumbirwo enetwork anoumbwa nefiber tissue isina chimiro ane anisotropy uye motility.
2. Mvura inoyerera zvakanyanya. Inogona kuchengetedza mvura inoyerera zvakanaka pasi pekumanikidzwa kwevhu.
3. Kuramba ngura. Iine polypropylene kana polyester nedzimwe fiber dzemakemikari sezvinhu zvakagadziriswa, kuramba acid nealkali, kusaora, kusaita moth, uye kusaita oxidation.
4. Kugadzirwa kuri nyore. Kurema kuri nyore, kuri nyore kushandisa.
Kushandiswa
1. Kuparadzanisa zvinhu zvekuvaka zvine hunhu hwakasiyana, kuitira kuti pasave nekurasikirwa kana kusanganiswa kwezvinhu zviviri kana kupfuura, kuchengetedza chimiro chose uye mashandiro echinhu chacho, uye kusimbisa kugona kwekutakura mutoro kwechivako.
2. Kana mvura ichiyerera kubva muvhu rakatsetseka ichienda muvhu rakatsetseka, kupenya kwayo kwakanaka uye kupenya kwemvura zvinoshandiswa kuita kuti mvura ipfuure nepakati, uye zvinobudirira kubata zvidimbu zvevhu, jecha rakatsetseka, matombo madiki, nezvimwewo, kuchengetedza kugadzikana kwevhu nehunyanzvi hwemvura.
3. Chinhu chakanaka chinofambisa mvura, chinogona kugadzira nzira yekubuditsa mvura mukati mevhu uye kubvisa mvura yakawandisa negasi muvhu.
4. Kushandiswa kwezvishandiso zve geotextile zvinonamirwa kuwedzera simba rekusimba uye kugona kuchinja kwehukuru hwevhu, kuwedzera kugadzikana kwechimiro chechivako, uye kuvandudza mhando yehukuru hwevhu.
5. Kuparadzira, kutamisa kana kuodza zvinobudirira kushushikana kwakasimba kudzivirira ivhu kuti risakuvadzwe nemasimba ekunze.
6. Shandisa pamwe chete nezvimwe zvinhu (kunyanya asphalt kana purasitiki) kuti ugadzire chipingamupinyi chisingapindi mvura muvhu (chinonyanya kushandiswa pakugadzira mugwagwa mukuru, kugadzirisa, nezvimwewo).
7. Inogona kushandiswa zvakanyanya mukuchengetedza mvura, magetsi emvura, migwagwa mikuru, njanji, zviteshi zvengarava, nhandare dzendege, nzvimbo dzemitambo, matunnel, mahombekombe egungwa, kugadzirisa, kuchengetedza zvakatipoteredza nedzimwe nzvimbo, kutamba kupatsanurwa, kusefa, kudhonza mvura, kusimbisa, kudzivirira, uye kuvhara basa.
