考慮以上要(yao)素(su),規劃選用壩式路(lu)堤方式填筑路(lu)基(ji),設(she)置高位(wei)涵(han)。涵(han)洞(dong)進口側邊(bian)坡(po)(po)鋪(pu)設(she)復(fu)合土工膜,以避免水(shui)流(liu)下滲穿(chuan)透路(lu)基(ji),并在(zai)其(qi)上設(she)置護(hu)坡(po)(po),減(jian)小(xiao)水(shui)流(liu)對路(lu)基(ji)邊(bian)坡(po)(po)的直接沖刷(shua),匯水(shui)在(zai)涵(han)洞(dong)進口側溝道內進行淤積沉(chen)沙(sha)后經過排(pai)水(shui)涵(han)排(pai)離(li)路(lu)基(ji)。
不論從施工(gong)(gong)工(gong)(gong)期、施工(gong)(gong)難度、施工(gong)(gong)質(zhi)量(liang)及(ji)環境保(bao)護方面都具有(you)不行(xing)比較的(de)。因此,鋼波紋涵管的(de)推(tui)廣應用在黃土區(qu)域(yu)公路建設(she)中(zhong)有(you)著廣闊的(de)前景。鋼波紋涵管具有(you)管節薄,重量(liang)輕,便(bian)于運(yun)輸寄存,施工(gong)(gong)工(gong)(gong)藝簡略,現場(chang)安裝便(bian)利,處(chu)理(li)北(bei)方冰冷區(qu)域(yu)對橋梁(liang)和(he)管涵的(de)結構(gou)損壞問題,組裝快(kuai)速(su),工(gong)(gong)期短等長處(chu)。
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.

為避免鋼波紋涵(han)(han)(han)管(guan)銹蝕,波紋管(guan)節出廠前表(biao)里外(wai)表(biao)和緊(jin)固銜接螺栓,進行了熱浸鍍(du)鋅處理,鍍(du)鋅層厚度≥63μm,平均鍍(du)鋅層厚度84μm;施工(gong)安裝時增(zeng)涂瀝青涂層,其規劃運用年限100年。沿(yan)線跨(kua)溝(gou)位(wei)置路(lu)基填土高度48米,在(zai)溝(gou)底設(she)涵(han)(han)(han),涵(han)(han)(han)長將達到200多米。
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/
