供應鋼波紋涵管 金屬波(bo)紋(wen)管(guan)涵洞橋梁專(zhuan)用拼裝整裝鋼制波(bo)大口徑(jing)排(pai)水(shui)管(guan)

鋼(gang)波紋(wen)管(guan)軸線(xian)上(shang)的波紋(wen)大(da)(da)(da)大(da)(da)(da)增加了截面慣(guan)性(xing)矩，提高(gao)了承載力(li)，又因為其(qi)周圍土體能(neng)夠結(jie)合鋼(gang)波紋(wen)骨一同受力(li)，可以在更大(da)(da)(da)程度上(shang)將(jiang)荷載的集中應力(li)予(yu)以分散(san)。鋼(gang)波紋(wen)涵(han)管(guan)是替代圓管(guan)涵(han)、蓋(gai)板涵(han)、拱涵(han)和小橋(qiao)的優質公路建材。
