Ukugunda Ummango Ukuxuba Indlela En 깊이 (TRD)

Ukuphela Kwendlela Yokwakha Imathiraphu (TRD) iyindlela yokwakha imithambo ejulile ye- in-situ edala odongeni abathwala carga ngokulandelana ukusika nokuhlanganisa umhlabathi ngempahla ye-cement-based binder ngenqubo yokumbiwa eqhubekayo. Ethuthukiswe ikakhulukazi eJapane, ubuchwepheshe be-TRD bubonisa ukuthuthuka emndenini wezobuchwepheshe bokuhlanganiswa komhlabathi, bujabulisa isikhundla esicacile phakathi kwe-Cutter Soil Mixing (CSM) tradicional kanye nokwakhiwa kwemithambo yokuhambisa. Le ndlela iklanyelwe ukukhiqiza odonga oluhlangene, olwalungile ngokwakhiwa ngokusebenzisa ukusika kwemishini kanye nokuhlanganiswa okujulile komhlabathi wendawo ne-cementitious slurry, kudala imikhawulo emikhulu enezinga lesikhumba elilawulwayo kanye nesici sokuphumula. Izicelo eziyinhloko ze-TRD zifaka ukwakhiwa kwemishini yokuphothula emitholampilo ewumbululu, imithambo yokuhambisa esekela ukuphela kokwakhiwa kokubanjwa, izakhiwo zokulawula ukuvuza ekwakhiweni kwezimvula, kanye nemithambo yokuphakela imithombo efakwe phansi. Ubuchwepheshe be-TRD buphumelela kakhulu lapho ukufinyelela ezindaweni kuthinta ukufakwa kwezinhlelo ezijwayelekile zepayipi yesikhumba noma izinhlelo ze-soldier pile, lapho izimo zomhlabathi zisho izinkinga kumishini ejwayelekile yokuthatha imithambo, noma lapho izidingo zobunjiniyela zidinga izingxenye zomzimba ezizungezile, ziqonde ngqo ngaphandle kokuphuka. Le ndlela iphinde isetshenziswe ezindaweni zomhlabathi soft, ezingavunyelwe kahle, zeziqubulo kanye ne-geologies ehlangene lapho izindlela zokuh excavate ezijwayelekile zikhombisa ukufaneleka okuphansi noma zikhulisa ukuncika nokukhala ngokweqile. Inqubo ye-TRD isebenza ngemuva kwemishini yokuphothula eyenziwe ngendlela eyodwa ejabulele ukusika amaqanda agijimayo noma ama-drums okuphephisa umhlabathi ngokujulile. Njengoba ikhanda lokusika lihamba phambili phezulu noma ngezindlela ezibekiwe, i-cementitious slurry iyasetshenziswa ngqo emkhakheni wokusika futhi ihlanganiswa nezinto ezithathiwe, kudala ubuningi obuthambile obufakwa emgqonyeni ngemuva kokusika. Ukuphana kwezilonda ezikhiqizwayo kudala ibhodi eyodwa, enobukhulu obubambekile. Umthamo wokuqonda, ububanzi bokusika, kanye nezinga lokuhlanganiswa kusebenza ngokuphakanyiswa kwezinhlelo ze-hydraulic, kuvumela abakhiqizi ukuba balungise izincazelo zomoya ukuze zibe nezidingo zephrojekthi. Ukuhlolwa kwesikhathi esiqondile kwevolumu ye-slurry, ingcindezi yokungenisa, nokumelana kokusika kunikeza ukuqinisekiswa kwekhwalithi ngesikhathi sokufakwa. Imishini esigabeni se-TRD ifaka imishini yokukhiqiza ephelele efakwe emishinini edonsayo emikhulu noma ezindaweni ezithathwe, eziklanyelwe ama-panel avamise ukuphakanyiswa kusuka ku-0.8 kuya ku-3.0 meters ububanzi futhi ikwazi ukufinyelela ukujula kusuka ku-20 kuya ku-100 meters ngokwentela izimo zomhlabathi nemishini. Ukujola kuhlanganisa izikhanda zokusika ezilodwa nezikhandi eziningi, ezinezinga elihlukile lokujubane kokujikeleza nezikhalazo zokujikeleza ukuze zifanele izitayela zomhlabathi eziluhlaza. Imishini ephathelene ibandakanya izinyathelo ze-slurry, ama-centrifuge yokuphatha i-slurry, izinhlelo zokufaka imikhawulo nezinhlelo zokuhlola ikhwalithi. Izizathu zokukhetha izinhlelo ze-TRD zifaka izimfuneko zokuqonda kwamaphrojekthi, ububanzi be-wall kanye nokuphatha, iphrofayili yomhlabathi nezifiso zamandla, izidingo ze-permeability yomoya nezidingo zokuphelela, ukufinyelela endaweni nezithiyo zomhlaba, ukuphuculwa kwezinto ezithathiwe, kanye nebhajethi yokuhamba kwemishini nakwezokusebenza. Abakhi bahlola ukuqina kwamathuluzi okusika, izinga lokusetshenziswa kwe-slurry, izikhathi zokuphindaphinda, nezidingo zokuhambisana nemvelo. Izindinganiso ezifanele, kuhlanganisa i-ISO 21010 (Izingxenye Zokwakha) kanye nezinqubo zomphakathi zokwakha, zilawula ukwakhiwa kwemithambo ye-TRD, izincazelo zezinto, kanye nekhwalithi yokusebenza, kanti i-DIN 4126 ne-EN 1537 zinikeza umhlahlandlela kuzakhiwo zokwesekwa zesikhashana nezihlala isikhathi eside ezihlanganisa imithambo ye-TRD.
