Hongyue tri-cabbir geonet ka kooban oo biyo-mareen ah
Sharaxaad Gaaban:
Shabakadda dhul-daaqsimeedka saddex-geesoodka ah waa nooc cusub oo walxaha geosynthetic ah. Qaab dhismeedka ka kooban yahay saddex-geesood xudunta u ah geomesh, labada dhinac waxaa lagu dhejiyay irbado jootextiles aan tolmo lahayn. Xudunta geonet-ka 3D waxa ay ka kooban tahay feeraha toosan oo dhumuc weyn leh iyo feeraha dabada leh ee sare iyo hoose. Biyaha dhulka hoostiisa si degdeg ah ayaa looga soo dayn karaa wadada, waxayna leeyihiin nidaam dayactirka daldaloolada kaas oo xannibi kara biyaha xididada ee culeyska sareeyo. Isla mar ahaantaana, waxay sidoo kale door ka ciyaari kartaa go'doominta iyo xoojinta aasaaska.
Sharaxaada Alaabta
Badbaadada iyo nolosha adeegga ee tareenada, jidadka iyo mashaariicda kale ee kaabayaasha gaadiidka ayaa si dhow ula xiriira habka bullaacadaha iyaga u gaar ah, kaas oo qalabka geosynthetic waa qayb muhiim ah oo ka mid ah nidaamka bullaacadaha. Shabakadda dheecaanka saddex-geesoodka ah ee isku-dhafka ah ee saddex-geesoodka ah waa nooc cusub oo ah walxaha geosynthetic, shabakada saddex-geesoodka ah ee isku-dhafka ah ee isku-dhafka ah waa nooc cusub oo ah walxaha geosynthetic. Shabakadda geodrainage-ka ee saddex-geesoodka ah waxay ka kooban tahay qaab-dhismeed saddex-geesood ah oo mesh balaastiig ah oo laba-geesood ah oo isku xiran geotextile, waxay bedeli kartaa ciidda dhaqameed iyo lakabka quruurux, inta badan loo isticmaalo qashin-qubka, sariiraha iyo qulqulka gidaarka gudaha ee tunnel.
Tilmaamaha Alaabta
Geonet-ka isku-dhafan ee saddex-geesoodka ah ee biya-baxa waxay ka samaysan tahay geonet saddex-cabbir ah oo gaar ah oo ku dahaadhay geotextile labada dhinac. Waxay leedahay hantida geotextile (shaandhaynta) iyo geonet (daaqadaha iyo ilaalinta) waxayna siisaa nidaam shaqeynaya "ilaalinta sifeynta-dareemada". Qaab-dhismeedka saddex-geesoodka ah wuxuu qaadi karaa culays sare oo xagga dhismaha ah wuxuuna ahaan karaa dhumuc gaar ah, xoog iyo heer sare ah xagga socodka biyaha.
Baaxadda Codsiga
Biyo-baxa qashin-qubka; Biyo-mareenka Jidadka hoose iyo laamiga; Xoojinta qulqulka qulqulka dhulka jilicsan ee tareenka; Biyo-mareenka hoose ee tareenada, ballastka tareenka iyo qulqulka ballast, qulqulka tunnel-ka; Dheecaannada dhismaha dhulka hoostiisa; Haysashada dareeraha dhabarka ee gidaarka; Jardiinooyinka iyo garoommada ciyaaraha ayaa dareera.
