Drainage sethusathuto bakeng sa naha saeteng

E mong le e mong wa ba matlo ea teropong ea sebele o hlokomela hantle haholo ea kamoo mathata haholo tlisa mobu waterlogged, haholo-holo haeba naha site e teng sebakeng se tlase. Tabeng ena, ho sesebediswa drainage hlokahala. ke kotsi e tletse lintho tse ngata mongobo feteletseng sebakeng seo ea teropong eng? Waterlogging ya mobu ka lebaka la ho palo e khōlō ea pula le qhibiliha lehloa baka kotsi lirapa e seng feela, empa hape ka ho toba sebakeng ka naheng ea sebopeho lona.

Ka nako e telele stagnation ya mongobo e isa ho lefu la joang bo mohloa, lipalesa serapeng le lifate tsa litholoana, e le bakeng sa ntshetsopele ya bokgoni ho tloaelehile ea tsamaiso motso hloka oksijene, e leng mobung metsi ke hoo e batlang e che. Bakeng sa mehaho waterlogging ea mobu hape sokela timetso ea sebopeho motheo, ho thusa hore ho ponahalo ea likokoana-hloko dithulaganyo mofuta (fungus e hlobo, microorganisms tse fapa-fapaneng) kamoreng e ka tlaase. Hangata sena se etsa hore tahlehelo ea thepa ea mogote ka lebaka la ho dithulaganyo le deformation etsahala dibopeho tsa mamati le lifensetere.

Seo e fana ka sesebediswa sa drainage, 'me seo mefuta lona ke moo? Drainage - tsamaiso ea lipeipi le mehaho tšehetso hore fokotsa tlase ho lefatshe ka tsela e feteletseng kapa metsi mobu-khatello. Ho finyella sena, tlas'a boemo ba nka ba fumana tlase ho lefatshe Hatisa rala liphaephe perforated mofuta le itseng le masoba le bophara ba ka mabota bona. sebakeng seo sesebediswa drainage o etsoa ka litsela tse peli ka sehloohong - holim (mola) le tebileng.

Ho ka potlako tlosa metsi feteletseng, e leng e thehiloe ke pula le qhibiliha lehloa selemo, sesebediswa e sebetsa le drainage ho pota ka tlung ka ntle feela tsela. Bakeng sa ho tlosa metsi fatše, e leng ka ka botebo ba millimeters ho fihlela ho 1700 e sebediswa ke sesebediswa tebileng drainage. Tsena mefuta e 'meli ea drainage ka ho kopantswe tsamaisong e le' ngoe le ho sebetsa ntle rarahaneng e le 'ngoe. Pele ho sebetsa ka sesebediswa sa ho bohlokoa ho ba le tsamaiso ea drainage ea mobu Tlhahlobo le litekanyo infield botebo tsa metsi fatše. Technology oona tsamaisong disebediswsa drainage a qala ho mefuta e tsa lona tse peli tse: bulehileng le koaloa.

Tsamaiso bulehileng ya tebileng sesebediswa bulehileng-a tsoelang e theko e bonolo le e fokolang haholo. E bolaoa ka mokgwa wa epile liforo bulehileng, maemong a sa tloaelehang le e thehilweng diterei la konkreite, eo ba na le tšekamelo ikutloeleng metsi ho noa sesebediswa (drainage liliba).

Matšeliso a phahameng ka ho fetisisa le durability ka tshebetso e koetsoeng mofuta drainage sesebediswa. Bakeng sa tlhomamiso lona lokela ho qala ka cheka foro, botebo seo ka sona ke ho tloha 700 ho 1500 limilimithara le bophara - seng ka tlase ho 500 limilimithara. Qetellong ea liforo lokisetsa lehlabathe kapa lejoe sithabetseng ho lokisetsa 100 limilimithara phahameng, 'me feela ka mor'a hore e etsa e rala liphaephe perforated drainage seo hangata se entsoe ka ceramic. Ka ho toba le thuso ea bona o ile a etsa pokello le ho tloswa ea tlase ho lefatshe ho jella ka hantle.
