Ngwaọrụ CFA

CFA tooling pụtara ihe ọrụ na ngwaọrụ dị mkpa maka ọrụ auger drilling nke na-enwekarị, otu ụdị iji kọwa akụkụ ndị dị n'okpuru ala n'oge ọrụ geotechnical. Kọgịọntụ a pụtara auger flights, hollow kelly bars, ihe nche, sistemụ coupling, na ngwaọrụ drilling ndị ọzọ e kere iji kerịha maka CFA rigs. Ngwaọrụ a ga-eme ka ọ dị mma n'ime ọrụ rotasionọl na axial forces mgbe ọ na-acha akụkụ, na-eme ka ozi na njikwa dị mma bụ ihe dị mkpa maka nsogbu ọrụ n'ịkọwa akụkụ. Auger drilling nke na-enwekarị bụ otu ụdị iji kọwa akụkụ ebe auger na-enwekarị na-aga n'okpuru ala mgbe ọ na-ekpuchi soil site na auger flights. Mgbe auger rie ihe dị mkpa nke drilling depth, concrete nke dị mma na-pump site na hollow kelly na-agbanwe site na auger column mgbe auger flights na-achụ, na-ekpuchi soil na-eme akụkụ concrete. Ngwaọrụ CFA ga-eme ka ọ dị mma maka ọrụ ndị abụọ a, auger flights e kere iji ekpuchi spoil site na ihe dị iche iche dị ka clay, silt, sand na gravelly deposits. Ngwaọrụ nche na auger tip ga-eme ka ọ dị mma n'ime strata abrasive, dị ka weathered rock na mixed face conditions, mgbe ọ na-acha bore stability ọ bụghị bentonite ma ọ bụ polymer support fluids, ihe dị mma nke dị mkpa karịa ọrụ akụkụ ndị ọzọ. Ngwaọrụ e jiri na CFA ọrụ pụtara flight augers nke dị pitch na diameter, sistemụ hollow kelly nke na-enye concrete, extension rods na connectors nke na-enyere aka mee ka ngwaọrụ dị otu, na cutting heads dị iche e kere maka ihe dị n'okpuru ala. Rotary heads na drive systems na-enye rotasionọl nke dị mkpa maka boring, mgbe sistemụ concrete delivery na-pump ga-eme ka ọ dị mma site na auger extraction rates. Ngwaọrụ CFA na-enye aka maka ihe dị iche iche, site na soft clays ebe torque dị nta, ruo dense sands na weak rock formations nke chọrọ ngwaọrụ nwere ike na-enweghị nchekwa. Ihe a na-enye aka na CFA drilling bụ otu ụdị iji kọwa akụkụ n'ụlọ, bridge substructures, na ọrụ infrastructure n'ime urban na industrial sites ebe njikwa space na ihe dị mma maka ala na-enye aka karịa ọrụ akụkụ nke na-enweghị auger. Ọrụ maka CFA tooling pụtara ụlọ ọrụ, complex residential, transportation infrastructure, na ọrụ civil engineering dị iche ebe akụkụ dị mkpa n'ọrụ ọ bụghị ground disturbance dị elu. Ihe dị mma nke ọrụ a n'ịrụ ọrụ land contaminated, ebe avoidance of spoil heaps na-eme ka environmental impact dị nta, na-enye aka karịa. Onye ọrụ professional na onye kọwa akụkụ na-ejere CFA tooling dị mma iji rie ohere, dị mma maka ala, na akụkụ dị mma n'ime ọrụ dị elu na ihe dị mma nke ọrụ construction n'ụwa.
