鋼波紋涵管的(de)很多(duo)選用加快(kuai)了(le)項目施工進度,路基完工至今,高填(tian)土路段均未產生沉降,路基安(an)穩,涵(han)洞(dong)結構未產生較大(da)變形,很好的(de)習慣了(le)地(di)質條件(jian),排水順利。該結構的(de)應(ying)用有效的(de)處理了(le)在填(tian)方路基上(shang)及地(di)基承載力較低(di)路段構筑長涵(han)洞(dong)引(yin)起不均勻沉降的(de)問題,與鋼筋混凝土結構比較。

考慮(lv)以(yi)上要素,規(gui)劃(hua)選用壩式(shi)路堤方式(shi)填筑路基,設置高位涵(han)。涵(han)洞(dong)進(jin)口(kou)側(ce)邊(bian)坡(po)鋪設復合土工膜,以(yi)避免水(shui)流(liu)下滲穿透路基,并在其上設置護坡(po),減小水(shui)流(liu)對路基邊(bian)坡(po)的直接沖(chong)刷,匯水(shui)在涵(han)洞(dong)進(jin)口(kou)側(ce)溝道內進(jin)行淤積(ji)沉沙后經過(guo)排水(shui)涵(han)排離路基。
不論從(cong)施工(gong)(gong)工(gong)(gong)期、施工(gong)(gong)難度(du)、施工(gong)(gong)質量及環境保(bao)護方面都(dou)具有不行(xing)比較的。因此,鋼波(bo)紋涵(han)管的推(tui)廣(guang)應用在黃(huang)土區域(yu)公路建設中有著廣(guang)闊(kuo)的前景。鋼波(bo)紋涵(han)管具有管節薄,重量輕,便于(yu)運輸寄存,施工(gong)(gong)工(gong)(gong)藝簡(jian)略,現(xian)場安裝便利,處理北方冰冷(leng)區域(yu)對橋梁和管涵(han)的結(jie)構損(sun)壞(huai)問題,組裝快速,工(gong)(gong)期短等長處。
No matter from the aspects of construction period, construction difficulty, construction quality and environmental protection. Therefore, the popularization and application of steel corrugated culvert pipe has broad prospects in highway construction in loess area. The steel corrugated culvert pipe has the advantages of thin pipe joint, light weight, convenient transportation and storage, simple construction process, convenient on-site installation, handling the structural damage of bridges and pipe culverts in the cold area in the north, fast assembly and short construction period.

為(wei)避免鋼波紋涵管(guan)銹(xiu)蝕,波紋管(guan)節出廠前表里外表和緊(jin)固(gu)銜接(jie)螺栓,進行了熱浸鍍鋅處(chu)理(li),鍍鋅層厚度≥63μm,平均(jun)鍍鋅層厚度84μm;施工安(an)裝時增涂(tu)瀝(li)青涂(tu)層,其規劃運用年限100年。沿線(xian)跨溝位置路基(ji)填土高度48米(mi),在溝底設涵,涵長將達到200多米(mi)。
由于涵身較長,管節較多,溝底縱坡較大,如果選用混凝土板涵,因高填土原因很簡略造成管節的不均勻沉降及涵管裂縫,且對根底處理要求較高,一起蓋板涵施工工期較長,涵洞損壞后維修困難。而鋼波紋涵管分片重量輕,組裝簡便,施工工期短,安裝后整體性及連續性較好,力學性能優。//hanihanbj.com/
