供應鋼波紋涵管 金屬波紋管涵洞(dong)橋梁專用拼裝整裝鋼制波大口(kou)徑(jing)排水(shui)管

鋼(gang)(gang)波(bo)(bo)紋(wen)管(guan)軸線上(shang)的波(bo)(bo)紋(wen)大(da)大(da)增加了(le)截(jie)面慣(guan)性(xing)矩，提高了(le)承載力，又因為其周圍土體能夠(gou)結合(he)鋼(gang)(gang)波(bo)(bo)紋(wen)骨一同受力，可以在更大(da)程度上(shang)將荷載的集中應力予以分散(san)。鋼(gang)(gang)波(bo)(bo)紋(wen)涵(han)管(guan)是替代圓管(guan)涵(han)、蓋(gai)板(ban)涵(han)、拱涵(han)和小(xiao)橋的優(you)質公(gong)路建材。
