I-Geocell iyigridi enezinhlangothi ezintathu eyakhiwe ngokuxhuma imichilo ebanzi ye-polymer ngokusebenzisa i-ultrasonic welding nezinye izindlela.Ngemva kokwembuleka, yenza ukuma kwekhekheba lezinyosi futhi ilula.Isetshenziswa ekwakhiweni kobunjiniyela ukunciphisa ukuguguleka, ukusimamisa inhlabathi, ukuvikela imigudu, nokuhlinzeka ngokuqiniswa kwesakhiwo ukuze kusekelwe umthwalo nokugcinwa kwenhlabathi.
Ukusebenza okuhle kakhulu kobunjiniyela kwamaseli e-geotechnical kuwenza adlale indima ebalulekile emkhakheni wokwakha ubunjiniyela.Amandla kanye ne-modulus ye-geocell kuphakeme ngokuqhathaniswa, futhi yengezwa njengokuqiniswa okuqinile emhlabathini ukuze kwakheke ungqimba lwesakhiwo oluguquguqukayo.Ingahlakaza umthwalo ogxilile engxenyeni engenhla, ithuthukise amandla nokuqina kwenhlabathi, inciphise ukuguquguquka, futhi ithuthukise umthamo wokuthwala wesisekelo esithambile.Ngesikhathi esifanayo, iphinde ibe nezindawo zamakhemikhali ezizinzile ezifana nokumelana ne-asidi ne-alkali, ifanele izindawo ezihlukahlukene ze-geological.Ngenxa yezinzuzo nezici ze-geocell ngokwayo, izinto zayo zokugcwalisa zingatholakala endaweni, futhi zingakhula futhi ziwe ngokukhululekile ngesikhathi sokuthutha, okunganciphisa kakhulu izindleko zobunjiniyela.
1.Ukuqiniswa kwesisekelo senhlabathi ethambile
Ezweni elinezimo ze-geological eziyinkimbinkimbi, ngenxa yamandla aphansi kanye nokucindezelwa okuphezulu kwenhlabathi ethambile, kulula ukubangela ukulimala kwesisekelo noma ukuhlaliswa, okuthinta kakhulu ukuphepha kwamaphrojekthi wobunjiniyela.Ukuvula i-geocell esisekelweni senhlabathi ethambile nokugcwalisa iseli ngalinye ngezinto ezidonsa amanzi eziyimbudumbudu ukuze kwakhiwe isakhiwo somcamelo ozinzile kungathuthukisa ngempumelelo amaphutha esisekelo senhlabathi ethambile futhi kwandise amandla okuthwala isisekelo.
2.Ukuvikelwa komthambeka
Ukuvikela i-slope kungenye inkambu ebalulekile yokusetshenziswa kwama-geocell.Ama-Geocell anamandla amahle kanye nokuqina, futhi angakha amayunithi aqhubekayo ezinto zokugcwalisa ngokuhlangana okuphansi, okwandisa ukuzinza kwezinto zokugcwalisa ezihlakazekile.Zinemiphumela emihle yokuvikela ekuqiniseni ukuzinza kokwakhiwa kwemithambeka kanye nokunciphisa ukuguguleka kwe-hydraulic, okusiza ukuxazulula uchungechunge lwezinkinga zemvelo nezobunjiniyela ezifana nokulimala kwezitshalo, ukuguguleka komhlabathi, ukudilika kwenhlabathi, nokuntengantenga kwemithambeka.
3.Ukwakhiwa kobunjiniyela bomgwaqo
Ama-geogrid angavimbela ngempumelelo ukuwohloka kwenhlabathi ngenxa yomthwalo omningi.Uma zisetshenziselwa ubunjiniyela bomgwaqo, zingathuthukisa kakhulu amandla onke okugcwalisa noma ukuzinza kwesisekelo, ukunciphisa ukuvela kwezifo ezifana nokuqhekeka okuqondile nokuvundlile kanye nokuhlala komgwaqo.Badlala indima ebalulekile ekuqinisekiseni ukusebenza ngokuphephile kwemigwaqo kanye nokwelula isikhathi sokusebenza konjiniyela bemigwaqo, ikakhulukazi ukubhekana nemigwaqo egcwele ingxenye kanye nembiwe ingxenye Imibhede yemigwaqo ezindaweni ezinomoya kanye nesihlabathi idlala indima ebalulekile.
4.Isetshenziselwa ubunjiniyela bokugcwalisa i-abutment
Ukuphuka nokungalingani kwesitebhisi esingemuva sebhuloho akuholeli nje kuphela ekugxumeni kwemoto ekhanda lebhuloho, kodwa futhi kusheshisa ukulimala kokuhlehla kwebhuloho, amajoyinti okunwetshwa kwekhanda lebhuloho, kanye nokuhamba ngezinyawo okuhlangene.Ukusetshenziswa kwamaseli e-geogrid ngemuva kwe-abutment kungasebenzisa ukukhiya nokuqinisa imiphumela yezimbobo zamaseli e-geogrid emhlabathini, kukhuphule ukungqubuzana, ukukhiya, kanye nemiphumela yokuvimba inhlabathi, kuvimbele ukunyakaza okungemuva nokuhlaliswa kwenhlabathi, kuvimbela ngempumelelo ukugudluzwa kanye nokuhlaliswa kwenhlabathi, uthuthukise ukuzinza kwawo, futhi unciphise umehluko wokuguquguquka obangelwa izinto ezimbili ezihlukene zekhonkrithi ye-abutment kanye ne-backfill, ukuthuthukisa ngokuphumelelayo ukwenzeka kwe-bridge head jumping kanye nokuhlaliswa okungalingani kwenhlabathi.
Ukuhlolwa kwekhwalithi
Ukuhlolwa kwekhwalithi kwamaseli e-geotechnical ukuqinisekisa ukuthi amapharamitha awo ahlukahlukene ahlangabezana nezidingo zobuchwepheshe ezifanele kuyisixhumanisi esibalulekile sokulawula ikhwalithi yamaseli e-geotechnical.Ngenxa yokuthi amaseli ayisisekelo somkhiqizo, ngesikhathi senqubo yokuhlola, nakuba amanye amapharamitha okuhlola ezekhwalithi yamaseli, asadingeka ukuze kulawulwe ikhwalithi yomkhiqizo iyonke.
Lapho uhlola usayizi, amathuluzi okulinganisa afanelekile kufanele akhethwe ukuze kukale izilinganiso zezingxenye ezihlukene.Isibonelo, ubude obuningi bonqenqemeni oluvuliwe bulinganiswa nesilinganiso se-tape, ibanga le-welding kanye nokuphakama kweseli kulinganiswa nombusi wensimbi, futhi ubukhulu bulinganiswa ne-micrometer.Ukunemba kwethuluzi ngalinye lokulinganisa kufanele lihlangabezane nezidingo ezifanele.
Ukutholwa kwezinga lokushisa lokuthambisa i-Vicat nakho kubalulekile kumaseli e-geotechnical.Ingahlolwa ngokwendlela ye-A50 ezindleleni ezine zokuthi “Ukunqunywa kwezinga lokushisa le-Vicat softening (VST) lamapulasitiki e-thermoplastic” (GB/T 1633-2000), esebenzisa amandla angu-10N kanye nezinga lokushisa elingu-50 ℃/ h.Ngesikhathi sokulungiselela isampula, okungenani ama-specimens amathathu kufanele anqwabelene ngokuqondile ukuze kuzuzwe ukujiya okudingekile kwezibonelo, futhi isimo sezifanekiso kufanele silungiswe ngokuya ngokucaciswa okujwayelekile ngesikhathi sokuhlolwa.
Ngokwamazinga ahlukene, kungase kube nomehluko ezintweni zokuhlola nezindlela ezithile zokuhlola, ezihlobene ngokuqondile nezinkambu ezithile zohlelo lokusebenza zamakamelo e-geotechnical.Ngakho-ke, ukuhlolwa kwekhwalithi yamakamelo e-geotechnical kufanele futhi kusekelwe eqinisweni.Siphikelela ekusebenziseni izindlela zesayensi ukuze silawule ngokuqinile ikhwalithi.Uma unezidingo, sicela uchofoze emikhiqizweni ekuwebhusayithi ukuze nibonisane.Noma thumela imininingwane enemininingwane nolwazi lobunjiniyela, futhi sizoba nabasebenzi abangochwepheshe abazokunikeza ngamasevisi amahhala
