Ngwaọrụ ndị ọzọ

Ngwaọrụ ndị na-enyere aka na nrụpụta mgbidi sheet pile na mkpuchi mkpuchi gụnyere akụrụngwa, usoro, na akụkụ pụrụ iche nke na-eme ka ntinye, njikọ, iwepụ, na nkwado nke ihe ntọala bụ isi nwee ike. Usoro ndị a bụ akụkụ dị mkpa nke injinia ntọala miri emi, na-arụ ọrụ dịka usoro nnyefe ike, njikwa nhazi, na ndị na-eme ka arụ ọrụ nke na-emetụta àgwà owuwu, oge, na ọnụahịa. Mgbe ha bụ nke abụọ na mgbidi ma ọ bụ piles na-ebu ibu, akụrụngwa ndị na-enyere aka bụ ihe dị mkpa maka ịga nke ọma nke ọrụ niile ma na-anọkarị na nnukwu akụkụ nke itinye ego na akụrụngwa. Ngwaọrụ ndị na-enyere aka na-eji na ụdị niile nke mmezi ala kwụ ọtọ na usoro mkpuchi, gụnyere mgbidi sheet pile, nrụpụta mgbidi diaphragm, mkpuchi piles secant na tangent, usoro pipes tremie, na ntinye sheet piling nke mmiri. Na ngwa mgbidi sheet pile, akụrụngwa ndị na-enyere aka na-akwado ịkwanye piles, iwepụ piles, nlekota njikọ, na nkwado lateral. Na ọrụ mgbidi diaphragm, usoro ndị a na-achịkwa nkwụsi ike nke usoro nduzi, igbochi nrụgide hydrostatic n'oge a na-emegharị slurry, na nkwado akụrụngwa boring. Maka mkpuchi mkpuchi na mmezi gburugburu na dewatering, akụrụngwa ndị na-enyere aka na-eme ka nha ziri ezi na njikọ ụlọ na ala. Usoro ọrụ nke ọtụtụ usoro na-enyere aka na-adabere na nnyefe ike nke a na-achịkwa na njikọ geometric. Ụdị ịkwanye piles na nduzi na-enye nhazi kwụ ọtọ na damping iji nweta mmetụta ma ọ bụ ike vibration site na hammers, na-ekesa ike n'ụzọ ziri ezi na isi pile. Njikọ na clamps na circlips na-eme ka njikọ nke web nke mgbidi sheet pile nwee ike, na-egbochi ịkewa lateral n'okpuru nrụgide ala lateral. Akụrụngwa iwepụ na-eji usoro oscillatory ma ọ bụ rotational iji merie friction na adhesion, na-ewepụ piles nwayọọ nwayọọ site na ala gburugburu na-enweghị mmebi ụlọ. Usoro dewatering na njikwa slurry na-ejide equilibrium hydrostatic, na-egbochi ịda ụrọ na ịkwaga fines na-enweghị njikwa n'oge excavation na ntinye tremie. Ụdị akụrụngwa ndị na-enyere aka bụ isi gụnyere hydraulic na mechanical pile leads, extractors, usoro clipping na clamping, usoro nduzi na templates, ụlọ ọrụ dewatering na ọgwụgwọ slurry, usoro nlekota (inclinometers, piezometers, cells nrụgide), ụlọ nkwado (frames, wales, cross-bracing), na ihe eji eme ihe dịka additives mmiri drilling na mmiri hydraulic. Nhazi dị iche iche na-adabere na ibu pile, depth ịkwanye, ọnọdụ ala, na mgbochi saịtị. Nhọrọ nke usoro na-enyere aka chọrọ nyocha nke nkwado ibu, mechanics nke mmekọrịta ala na ụlọ, ọnọdụ gburugburu, na logistics nke arụ ọrụ. Ndị na-arụ ọrụ na-enyocha ibu pile (10–20+ tonnes kwa ihe), nchebe friction a na-atụ anya, depth ịkwanye, ọnụego mmepụta a chọrọ, na mgbochi ohere. Akụrụngwa ga-eme ka ọ bụrụ nke a pụrụ ịdabere na ya na igwe ntinye bụ isi ma na-anata ibu dynamic ma ọ bụ quasi-static na-enweghị mmebi. Nhazi na arụmọrụ nke usoro na-enyere aka na-achịkwa site na EN 12699 (piles a na-eme), EN 15237 (piles a na-eme na nha nta), DIN 4128 (mgbidi sheet), EN 14475 (mgbidi diaphragm), na API RP 2A (piles offshore). Ikike ibu, akara mmetụta, na tolerances njikọ na-enyocha site na ISO 13291 (ntinye mmetụta) na European Technical Approvals. Ịkwado na ụkpụrụ ndị a na-eme ka ụlọ ahụ dị mma, nchekwa ndị ọrụ, na ịdị n'otu n'ahịa mba ụwa.
