鐵(tie)路(lu)新III型枕是(shi)用于鐵(tie)路(lu)線(xian)路(lu)鋪設(she)的(de)基(ji)(ji)礎材(cai)料(liao)，是(shi)鐵(tie)路(lu)上(shang)部建筑的(de)重(zhong)要物資。鐵(tie)路(lu)新III型枕其作用是(shi)：固定鐵(tie)路(lu)軌道(dao)(dao)軌距(ju)，承載鋼(gang)軌及通(tong)過車輛的(de)重(zhong)量荷載，使軌道(dao)(dao)壓力荷載均勻分散傳遞至(zhi)路(lu)基(ji)(ji)，保持線(xian)路(lu)穩定暢通(tong)
鐵(tie)(tie)路(lu)(lu)(lu)新(xin)(xin)III型(xing)(xing)(xing)枕是用于(yu)鐵(tie)(tie)路(lu)(lu)(lu)線路(lu)(lu)(lu)鋪設的基礎材(cai)料(liao)，是鐵(tie)(tie)路(lu)(lu)(lu)上(shang)部建筑(zhu)的重(zhong)(zhong)(zhong)要物資。鐵(tie)(tie)路(lu)(lu)(lu)新(xin)(xin)III型(xing)(xing)(xing)枕其作用是：固定(ding)鐵(tie)(tie)路(lu)(lu)(lu)軌(gui)(gui)(gui)(gui)道(dao)軌(gui)(gui)(gui)(gui)距，承(cheng)載(zai)鋼(gang)(gang)軌(gui)(gui)(gui)(gui)及通(tong)過車輛(liang)的重(zhong)(zhong)(zhong)量荷(he)載(zai)，使(shi)軌(gui)(gui)(gui)(gui)道(dao)壓(ya)力荷(he)載(zai)均(jun)勻分(fen)散傳遞至路(lu)(lu)(lu)基，保持線路(lu)(lu)(lu)穩定(ding)暢(chang)通(tong)。鐵(tie)(tie)路(lu)(lu)(lu)新(xin)(xin)III型(xing)(xing)(xing)枕又(you)稱砼(tong)枕。由(you)混(hun)凝土，鋼(gang)(gang)筋，組合而成，外(wai)表堅硬，使(shi)用壽命長。軌(gui)(gui)(gui)(gui)枕按承(cheng)載(zai)能力分(fen)為I，II，III級，其中I型(xing)(xing)(xing)用于(yu)中型(xing)(xing)(xing)或輕型(xing)(xing)(xing)軌(gui)(gui)(gui)(gui)道(dao)；II型(xing)(xing)(xing)用于(yu)重(zhong)(zhong)(zhong)型(xing)(xing)(xing)和次(ci)重(zhong)(zhong)(zhong)型(xing)(xing)(xing)軌(gui)(gui)(gui)(gui)道(dao)；III型(xing)(xing)(xing)用于(yu)75kg/m鋼(gang)(gang)軌(gui)(gui)(gui)(gui)配套使(shi)用的特重(zhong)(zhong)(zhong)型(xing)(xing)(xing)軌(gui)(gui)(gui)(gui)道(dao)。
