3.3 Lalacewa kuma Bayyana Girman Buɗewa (AOS/O90)

• Izini (sec⁻¹): Yaya saurin ruwa ke wucewa ta cikin masana'anta a tsaye. Don ayyukan magudanar ruwa, mafi girma ya fi kyau.
• AOS (Bayanan Girman Buɗe): The size of the "holes" a cikin masana'anta. Dole ne a yi girman wannan bisa ga ƙasa. Idan ramukan sun fi girma fiye da barbashi na ƙasa, ƙasa ta bututu ta hanyar. Idan ramukan sun yi ƙanƙanta, ruwa ba zai iya wucewa ba. Ayyukan daidaitawa ne.

3.4 Resistance Huda, Dorewa, da Juriya na Muhalli

• Huda CBR: Wannan yana kwaikwayi mai ƙwanƙwasa yana turawa ta cikin masana'anta (kamar dutsen da ke ƙarƙashin nauyin babbar mota). Don masu jigilar ƙasa da sansanoni na hanya, huda CBR galibi shine ƙayyadaddun ƙayyadaddun bayanai.
• Juriya UV: Geotextiles sune polymers (Polypropylene PP ko Polyester PET). Hasken rana yana lalata su. Sai dai idan an baje kolin geotextiles na musamman tare da baƙar carbon da stabilizers, za su ragu cikin makonni. Dole ne a binne daidaitaccen farin geotextiles.

3.5 Me yasa Ba Za'a Yi La'akari da Siga Guda ɗaya a Keɓewa ba

I recently reviewed a project specification that called for "300 GSM fabric with high strength." Dan kwangilar ya sayi Nonwoven Heat-Bonded saboda yana da ƙarfi sosai. Koyaya, aikace-aikacen ya kasance magudanar ruwa na Faransa. Wurin da ke daure da zafi ya toshe nan da nan da yumbu, wanda hakan ya haifar da ambaliya. GSM yayi daidai, ƙarfin yayi daidai, amma nau'in da na'ura mai aiki da karfin ruwa dukiya sun yi kuskure.

4. Fahimtar Nauyin Fabric Geotextile (GSM) a cikin Ayyuka

4.1 Matsakaicin Matsalolin GSM da ake Amfani da su a Ayyukan Injiniya

Daga bayanan fitarwa na, ga yadda GSM ke yin taswirori ga gaskiya:

• 80-120 GSM: "Landscape Grade." Ana amfani da shi don shingen ciyawa, rabuwar lambun haske, ko bayan falafai. Ba don manyan ayyukan farar hula ba.
• 150-250 GSM: "Civil Standard." Kewayon dokin aiki. Ana amfani da shi don rabuwar hanya, magudanar ruwa, da shingen shinge na gaba ɗaya. 200 GSM shine abin da aka fi so a duniya don rabuwa tushe tushe.
• 300 - 400 GSM: "Heavy Duty." Ana amfani da shi don yadudduka na kariya na ƙasa, rip-rap ƙarƙashin ƙasa (ƙarƙashin manyan duwatsu), da kariya ta bakin ruwa.
• 500 - 800+ GSM: "Extreme Duty." Ana amfani da shi don kare geomembranes daga manyan duwatsu masu kaifi, mahimmancin mahalli, ko aikace-aikacen teku mai zurfi.

4.2 Dangantaka Tsakanin GSM, Kauri, da Ƙarfin Injini

A cikin marasa nau'in allura masu nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i) nau'i nau'i nau'i nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'i).

• Double the GSM $\approx$ Double the Thickness $\approx$ Double the CBR Puncture resistance.
• This is why engineers often just say "use 400 GSM." Suna ƙididdigewa a hankali cewa 400 GSM yana ba da kusan 3500N na juriyar huda, wanda shine amintaccen lamba ga manyan duwatsu.

4.3 Shin GSM mafi girma koyaushe yafi kyau?

A'a. GSM mafi girma yana nufin kauri, masana'anta mai yawa.

4.4 Rashin Fahimtar Jama'a Game da Nauyin Fabric Geotextile

Designers sometimes specify "woven 400 GSM" for filtration. This is a waste. A woven fabric achieves its strength through the yarn, not the mass. A 200 GSM woven might be stronger than a 400 GSM nonwoven. You don't buy woven fabric by weight; you buy it by tensile strength (e.g., "50kN/m woven"). You buy nonwoven fabric by weight/puncture.

5. Zaɓin Fabric Geotextile ta Aikace-aikace

5.1 Gina Hanya da Tsabtace Tafiya

• Matsala: The "pumping" tasiri. Motoci masu nauyi sun bi ta kan wata hanya, suna tura duwatsun kuma suna jifar yumbu sama. Tushen hanyar ya zama laka.

• Me yasa: Dole ne masana'anta ya kasance mai kauri wanda zai iya kwantar da ƙasa daga manyan duwatsu masu nauyi (Kariya) kuma ya ba da damar ruwan tide ya shiga da fita ba tare da ɗaukar ƙasa da shi ba (Tace).

5.5 Injiniyan Filaye da Muhalli

• Matsala: Kare geomembrane (HDPE liner) daga huda ta tsakuwar tarin leacha.
• Magani: Cushioning/Kariya.
• Zabi: 400-800 GSM Nonwoven (Staple fiber ne gama gari a nan).
• Me yasa: Manufar farko ita ce juriya ta CBR. Muna buƙatar shinge mai kauri, mai laushi. A cikin wuraren ajiyar ƙasa, muna ba da tabbacin masana'anta musamman don jure huda (misali, >2500N).

5.6 Na wucin gadi vs Aikace-aikacen Injiniya na Dindindin

Don hanyar ɗaukar kaya na ɗan lokaci (an yi amfani da shi har tsawon watanni 6), saƙa na GSM 150 na iya isa. Don babbar hanya ta dindindin, 250 GSM ci gaba da filament mara saka hannun jari ne a cikin shekaru 50 na kwanciyar hankali. Kada a wuce gona da iri don ayyukan wucin gadi, amma kar a taɓa ƙayyadadden ƙayyadaddun kayan aikin dindindin.

6. Yadda Ake Zaɓan Madaidaicin Geotextile Fabric don Yanayin Ayyuka

6.1 Yanayin Ƙasa da Halayen Ƙarƙashin Ƙasa

• Clay/Silt: Yana buƙatar tsananin girman tacewa (AOS). Yi amfani da mara saƙa.
• Dutsen Dutse/Kaifi: Yana buƙatar juriya huda. Yi amfani da Nonwoven mai nauyi (300g+).
• Soft Swamp (CBR < 3%): Yana buƙatar ƙarfafawa. Yi Amfani da Ƙarfin Ƙarfi Mai Ƙarfi.

6.2 Bukatun Load da Yanayin zirga-zirga

Idan titin zai ga manyan motoci masu hakar ma'adinai, damuwa na ƙasa yana da yawa. Daidaitaccen masana'anta na rabuwa bai isa ba; kuna buƙatar babban-modulus Woven Geotextile ko Geogrid composite don rarraba wannan kaya. Don hanyar masu tafiya a ƙasa, haske 120 GSM mara saƙa ya isa daidai.

6.5 Daidaita Bukatun Aiki da Kudin Ayyuka

Over-engineering is common. I have seen 600 GSM specified for simple driveway separation. This is a waste of money. A 200 GSM provides the same separation function. The extra 400g provides puncture resistance that isn't needed (since the subgrade is soft). We help clients "Right-Size" ƙayyadaddun su — saduwa da yanayin aminci ba tare da ƙone kasafin kuɗi ba.

7. Shawarwari na Geotextile Solutions ta Aikace-aikace (Bincike kawai)

9.2 Yin watsi da Ƙasa, Load, ko Yanayin Ruwa

Using a fabric with a small opening size (AOS) on a clay soil is a recipe for clogging. The fines will plaster against the fabric, creating an impermeable layer. We call this "blinding." Magudanar ruwa yana tsayawa, matsa lamba na ruwa yana ginawa, kuma tsarin ya gaza.

9.3 Ƙirƙirar Ƙirƙirar Ƙira da Ƙirar Kuɗi mara Bukata
