Zeziphi izicelo zokusetyenziswa kweemfumba zentsimbi eshushu eqengqelekayo kulwakhiwo lwetonela yangaphantsi?

Iimfumba zentsimbi yentsimbi ziyinxalenye ebalulekileyo yolwakhiwo lwetonela engaphantsi komhlaba, ebonelela ngenkxaso eyimfuneko kunye nokuzinza kwezakhiwo eziphantsi komhlaba.Kulwakhiwo lwe-tunnel ye-subway, ukusetyenziswa kwe-steel sheet pile yinto ephambili yokuqinisekisa ukhuseleko kunye nokuqina kweziseko zophuhliso.Kule nqaku, siza kuphonononga iintlobo ezahlukeneyo zeemfumba ze-larssen ezithengiswayo kunye nokubaluleka kwazo kulwakhiwo lwe-metro tunnel, ukucacisa iingenelo zokusebenzisa amashiti ensimbi ashushu.
Iintlobo zeemfumba zeshiti lentsimbi:
Kukho iintlobo ezahlukeneyo zeemfumba zentsimbi kwimarike, kubandakanywa nezidumileyoLarsen sheet iimfumba.Eyaziwayo ngoyilo lwazo oludibeneyo, ezi mfumba zinika amandla abalaseleyo kunye nokunyaniseka kwesakhiwo.Xa kuqwalaselwa izicelo zeemfumba kulwakhiwo lwetonela yemetro, iimfumba zeLarsen sheet zilukhetho lokuqala ngenxa yokukwazi ukumelana noxinzelelo oluphezulu olusecaleni kunye nokubonelela ngenkxaso ethembekileyo kwiimeko ezinzima phantsi komhlaba.
Umthengisi wemfumba yentsimbi:
Ukufumana ababoneleli bemifumba yeentsimbi ezifanelekileyo kubalulekile ekuqinisekiseni umgangatho kunye nokuthembeka kwezinto ezisetyenziswa kulwakhiwo lwetonela yemetro.Kubalulekile ukusebenza kunye nomthengisi ohloniphekileyo we-sheet sheet onikezela ngeentlobo ezahlukeneyoubungakanani sheet sheet imfumba ubukhulukunye namacandelo entsimbi yeemfumba zentsimbi ukuhlangabezana neemfuno ezithile zeprojekthi yakho.Ngaphezu koko, kubalulekile ukuqwalasela iHalga steel sheet piles ukuqinisekisa ukusebenza kakuhle kweendleko ngaphandle kokuthomalalisa umgangatho.

Imfumba yeshiti lelarssen elishushu eliqengqelekayo lisetyenziswa:
I-Larssen sheet sheet inamandla amakhulu kunye nokuqina.Xa isetyenziswa kulwakhiwo lwetonela kaloliwe ohamba ngaphantsi komhlaba, iimfumba zamaphepha e-larssen ashushu aqengqelekayo zibonelela ngenkxaso eyimfuneko yolwakhiwo ukumelana noxinzelelo olukhulu kunye neemfuno zokuthwala umthwalo wemo engqongileyo yangaphantsi komhlaba.Ukwabelana ngamava ekusetyenzisweni ngempumelelo kweemfumba zentsimbi ezishushu eziqengqelekayo kulwakhiwo lwetonela engaphantsi kwendlela kunokubonelela ngeenjineli kunye neengcali zokwakha.
Ukushwankathela, usetyenziso lweiimfumba sheet sheet, ingakumbi imfumba yeshiti lentsimbi yeharga eqengqelekayo, idlala indima eqinisekileyo ekwakhiweni kweetonela zikaloliwe.Ngokuqonda iintlobo zeemfumba zamaphepha ezikhoyo, ukusebenza kunye nabanikezeli abathembekileyo kunye nokusetyenziswa kweenzuzo zentsimbi yentsimbi eshushu, amaqela okwakha anokuqinisekisa ukhuseleko, ukuzinza kunye nobude obude beziseko ze-metro tunnel.
