公路鋼波紋(wen)管(guan)
鋼波紋涵(han)(han)管的發展在我們(men)高速公(gong)路建設(she)過程中,涵(han)(han)洞是(shi)一種常(chang)見的結構(gou)也是(shi)一種十分重(zhong)要的結構(gou),涵(han)(han)洞結構(gou)一直采用箱(xiang)涵(han)(han)、蓋板涵(han)(han)、圓涵(han)(han)管、拱涵(han)(han)等幾種型(xing)式,涵(han)(han)洞在施(shi)工中存在設(she)計繁瑣,施(shi)工時(shi)間周(zhou)期長,涵(han)(han)洞的孔徑周(zhou)期小容(rong)易(yi)出現沉降和跳(tiao)車等問題(ti)。
