供應鋼波紋涵管 金屬波(bo)紋管涵洞橋梁(liang)專用拼裝(zhuang)整裝(zhuang)鋼(gang)制波(bo)大口徑排(pai)水管

鋼(gang)波(bo)紋管軸線上(shang)的波(bo)紋大(da)(da)大(da)(da)增加(jia)了截(jie)面慣性矩，提(ti)高了承載力，又因(yin)為其周(zhou)圍土體能夠結(jie)合鋼(gang)波(bo)紋骨一(yi)同受力，可以在更(geng)大(da)(da)程度上(shang)將荷載的集中(zhong)應(ying)力予以分散。鋼(gang)波(bo)紋涵(han)管是(shi)替代(dai)圓(yuan)管涵(han)、蓋(gai)板涵(han)、拱涵(han)和小(xiao)橋的優質公路建材。
