dhogor ka samaysan caag geotextiles
Balaastik fidsan oo ka samaysan geotextile
Jootextile tolsan waa walxo geosynthetic ah oo laga soo tolay polypropylene iyo sharooto polypropylene ethylene oo ah walxo ceeriin ah.Waxaa si weyn loogu isticmaalaa injineernimada juqraafiyeed sida ilaalinta biyaha, awoodda korontada, dekedda, jidka weyn iyo dhismaha jidka tareenka.
1. Xoog sare oo ay sabab u tahay isticmaalka silig fidsan caag ah, waxay ilaalin kartaa xoog ku filan iyo dhererka xaaladaha qalalan iyo qoyan.
2. Iska caabinta daxalka Waxay u adkaysan kartaa daxalka muddo dheer ciidda iyo biyaha leh pH kala duwan.
3. Wanaagsanaanta biyaha Waxaa jira faraqyo u dhexeeya fiilooyinka fidsan, sidaas darteed waxay leedahay qulqulka biyaha wanaagsan.
4. Guryaha wanaagsan ee ka-hortagga-microbial-ka, oo aan waxyeello u geysan microorganisms iyo aboor.
5. Dhismaha ku habboon Sababtoo ah maaddadu waa mid fudud oo jilicsan, waxay ku habboon tahay gaadiidka, dhigista iyo dhismaha.
