Wụnye sheet pile na-emepụta nrụgide

Press-in sheet pile installation na-anọchite anya usoro displacement nke a na-achịkwa maka ịkwanye sheet piles n'ala na-enweghị ịmepụta vibration ma ọ bụ ụda dị ukwuu, na-eme ka ọ bụrụ teknụzụ dị mkpa na injinịa ntọala miri emi ebe ihe mgbochi gburugburu ebe obibi, nso nke ihe ndị dị mkpa, ma ọ bụ ọnọdụ ala siri ike chọrọ ịkwanye na eziokwu. N'adịghị ka usoro impact ma ọ bụ vibratory, teknụzụ press-in na-etinye nrụgide static a na-achịkwa na mgbakwunye na enyemaka vibratory nhọrọ iji mee ka piles na-aga n'ihu nwayọọ, na-enye njikwa ka mma banyere nhazi, ntọala, na displacement lateral n'oge usoro ntinye. Usoro press-in sheet pile na-eji na ụdị ọrụ dị iche iche gụnyere mgbidi secant na tangent maka nkwado excavation na cofferdams nke oge, cutoff curtains maka njikwa gburugburu ebe obibi na njikwa mmetọ, na owuwu mgbidi diaphragm na mpaghara obodo dị arọ ebe ụda na vibration bụ ihe a chọrọ. Teknụzụ a na-egosi uru pụrụ iche na ọnọdụ ala nwere ike dị elu, nnukwu granular deposits, ma ọ bụ layers ala na nkume ebe usoro vibratory ma ọ bụ impact nke ọdịnala ga-emepụta vibration dị ukwuu ma ọ bụ mepụta ọnụego penetration na-enweghị njikwa, na-eme ka eziokwu nke ọnọdụ ma ọ bụ mebie ihe ndị dị n'akụkụ. Usoro ọrụ na-ejikọta usoro hydraulic jacking siri ike nke na-etinye nrụgide static incremental—na-adịkarị 50–500 tonnes kwa pile dabere na ikike ngwá ọrụ—na mgbakwunye na enyemaka vibratory nke na-adịghị elu (12–18 Hz) iji belata friction ala na mee ka ịga n'ihu dị mfe. Ngwá ọrụ press-in na-ejikọta na piles dị adị ma ọ bụ usoro nkwado kwụsiri ike, na-ejide akụkụ pile ugbu a site na clamps e mere nke ọma, na-aga n'ihu nwayọọ mgbe ọ na-enyocha n'oge a na-eme ka ibu, displacement, na inclination site na sensọ jikọtara. Ozugbo akụkụ pile ruru n'ogbe zuru ezu, a na-etinye akụkụ ọzọ, na-ejide ya, na na-eti ya n'usoro. Usoro a na-achịkwa na-enye ndị na-arụ ọrụ ohere ịmaintain ezi vertical na lateral tolerances, kwụsị na omimi a họpụtara, ma ọ bụ wepụ piles kpamkpam maka ngwa oge. Nhazi ngwá ọrụ na ụdị a gụnyere vibratory pile presses na-ejikọta nrụgide static na modulation nke ugboro a na-achịkwa, usoro hydraulic press nwere nnukwu ikike maka ala siri ike ma ọ bụ siri ike, usoro beam nzaghachi na anchor piles nke na-eme ka ngwá ọrụ kwụsiri ike, clamps pile pụrụ iche e mere maka profaịlụ sheet pile pụrụ iche, na ngwá ọrụ wepụ igwe maka ntinye oge. Usoro oge a na-ejikọta load cells, inclinometers, na usoro ndekọ akpaka na-enye nkwenye data ntinye na-adịgide adịgide na ndekọ mgbe niile. Nhọrọ nke ihe ndị a na-atụle gụnyere ihe ndị a chọrọ nke ala (ndị na-adịghị arụ ọrụ shear strength, friction angle, cone penetration resistance), omimi ntinye a chọrọ, eziokwu nke ọnọdụ na tolerances, ụda na vibration gburugburu ebe obibi (na-adịkarị 75–85 dB na ebe a họpụtara), ohere dị na saịtị maka nhazi ngwá ọrụ, mgbanwe composition ala, ịnwe ihe mgbochi ma ọ bụ nkume, mkpa ọnụego mmepụta, na ma piles bụ ntinye mgbe niile ma ọ bụ nke oge. Ndị a na-emetụta ụkpụrụ gụnyere EN 12699 (ngwá ọrụ maka press-in driving nke displacement piles), EN 1997-1 (Eurocode 7—imewe geotechnical), DIN 4014 (mgbidi sheet pile), na API RP 2A (ndị na-eme atụmatụ ntọala).
