新III型軌(gui)枕(zhen)是(shi)用于鐵(tie)路(lu)線路(lu)鋪(pu)設的(de)基礎(chu)材料(liao),是(shi)鐵(tie)路(lu)上(shang)部建(jian)筑的(de)重(zhong)(zhong)要物資(zi)。新III型軌(gui)枕(zhen)其作用是(shi):固定(ding)鐵(tie)路(lu)軌(gui)道(dao)軌(gui)距,承載(zai)鋼(gang)軌(gui)及(ji)通過車(che)輛的(de)重(zhong)(zhong)量荷載(zai),使軌(gui)道(dao)壓力荷載(zai)均勻分散傳遞至路(lu)基,保持(chi)線路(lu)穩定(ding)暢通
新(xin)III型(xing)(xing)(xing)軌(gui)(gui)(gui)枕是(shi)用(yong)(yong)于(yu)鐵路(lu)(lu)線(xian)路(lu)(lu)鋪設的(de)基(ji)礎材料,是(shi)鐵路(lu)(lu)上部(bu)建筑(zhu)的(de)重(zhong)要(yao)物資。新(xin)III型(xing)(xing)(xing)軌(gui)(gui)(gui)枕其作用(yong)(yong)是(shi):固定鐵路(lu)(lu)軌(gui)(gui)(gui)道(dao)軌(gui)(gui)(gui)距(ju),承載(zai)鋼軌(gui)(gui)(gui)及通過車輛的(de)重(zhong)量荷載(zai),使軌(gui)(gui)(gui)道(dao)壓力荷載(zai)均勻分散傳(chuan)遞至(zhi)路(lu)(lu)基(ji),保持(chi)線(xian)路(lu)(lu)穩定暢(chang)通。新(xin)III型(xing)(xing)(xing)軌(gui)(gui)(gui)枕又稱砼枕。由混凝土,鋼筋,組(zu)合而成(cheng),外表(biao)堅(jian)硬,使用(yong)(yong)壽命長(chang)。軌(gui)(gui)(gui)枕按承載(zai)能(neng)力分為I,II,III級(ji),其中I型(xing)(xing)(xing)用(yong)(yong)于(yu)中型(xing)(xing)(xing)或輕(qing)型(xing)(xing)(xing)軌(gui)(gui)(gui)道(dao);II型(xing)(xing)(xing)用(yong)(yong)于(yu)重(zhong)型(xing)(xing)(xing)和次重(zhong)型(xing)(xing)(xing)軌(gui)(gui)(gui)道(dao);III型(xing)(xing)(xing)用(yong)(yong)于(yu)75kg/m鋼軌(gui)(gui)(gui)配套使用(yong)(yong)的(de)特重(zhong)型(xing)(xing)(xing)軌(gui)(gui)(gui)道(dao)。
