Intshayelelo ye Larsen sheet sheet imfumba

Yintoni iLarsen steel sheet imfumba?
Ngomnyaka we-1902, injineli yaseJamani egama linguLarsen yaqala yavelisa uhlobo lwemfumba yentsimbi ene-U-shared cross-section kunye nezitshixo kuzo zozibini iziphelo, ezathi zasetyenziswa ngempumelelo kubunjineli, kwaye kwathiwa ".Larsen Sheet Pile"Emva kwegama lakhe. Kule mihla, iLarsen sheet sheet piles ziye zaqatshelwa kwihlabathi jikelele kwaye zisetyenziswa ngokubanzi kwisiseko sokuxhasa imingxuma, iicofferdams zobunjineli, ukhuseleko lwezikhukhula kunye nezinye iiprojekthi.

I-Larsen steel sheet sheet ngumgangatho oqhelekileyo wamazwe ngamazwe, uhlobo olufanayo lwe-Lassen sheet sheet sheet oluveliswa kumazwe ahlukeneyo lunokuxutywa kwiprojekthi efanayo. Umgangatho wemveliso we-Larsen sheet sheet sheet wenze imimiselo ecacileyo kunye neemfuno kubukhulu becandelo elinqamlezayo, isitayela sokutshixa, ukubunjwa kweekhemikhali, iimpawu zomatshini kunye nemigangatho yokuhlola izinto, kwaye iimveliso kufuneka zihlolwe ngokungqongqo kwifektri. Ke ngoko, i-Larsen sheet sheet inomgangatho olungileyo wokuqinisekisa kunye neepropathi zoomatshini, kwaye inokusetyenziswa ngokuphindaphindiweyo njengempahla yenguqu, enenzuzo engenakubuyiselwa ekuqinisekiseni umgangatho wokwakha kunye nokunciphisa iindleko zeprojekthi.

 

Iintlobo zeemfumba zentsimbi ye-Larsen

Ngobubanzi obuhlukeneyo becandelo, ubude kunye nobukhulu, i-Larsen steel sheet piles inokwahlulwa ibe yimifuziselo eyahlukeneyo, kwaye ububanzi obusebenzayo bemfumba enye yeemfumba zentsimbi ezisetyenziswa ngokuqhelekileyo zineenkcukacha ezintathu, ezizezi 400mm, 500mm kunye ne-600mm.
Ubude beFumba leShiti leNsimbi linokwenziwa ngokwezifiso kwaye liveliswe ngokweemfuno zeprojekthi, okanye linokunqunyulwa libe ziimfumba ezimfutshane okanye lidityaniswe libe ziimfumba ezinde emva kokuthenga. Xa kungenakwenzeka ukuthutha iimfumba ezinde zentsimbi kwindawo yokwakha ngenxa yokukhawulelana kwezithuthi kunye neendlela, iimfumba zohlobo olufanayo zinokuthuthelwa kwindawo yokwakha kwaye emva koko zifakwe kwaye zande.
Larsen steel sheet imfumba impahla
Ngokwamandla esivuno sezinto eziphathekayo, amabakala ezinto eziphathekayo zeLarsen sheet sheet piles ezihambelana nomgangatho wesizwe ziyi-Q295P, Q355P, Q390P, Q420P, Q460P, njl., kwaye ezo zihambelana nomgangatho waseJapanSY295, SY390, njl. Amanqanaba ahlukeneyo ezinto eziphathekayo, ukongeza kwiikhemikhali zazo, zinokudityaniswa kwaye zandiswe. Amabakala ahlukeneyo ezinto eziphathekayo ngaphezu kokubunjwa kweekhemikhali ezahlukeneyo, iiparamitha zayo zomatshini nazo zihluke.
