并作(zuo)必要的(de)防(fang)滲處理;為防(fang)止路(lu)基土(tu)堵塞涵(han)(han)洞洞口,在洞口與路(lu)堤交匯處做(zuo)一定(ding)高度和厚度的(de)漿砌片石或干砌片石墻(也可采(cai)用鉛(qian)絲石籠)防(fang)護。金屬波紋(wen)涵(han)(han)管是一種柔(rou)性結(jie)(jie)構,波紋(wen)管在結(jie)(jie)構上具有(you)(you)橫向補償位移(yi)的(de)優良特(te)性,可充分發揮(hui)鋼材抗拉性能(neng)強、變形性能(neng)優越的(de)特(te)點(dian),具有(you)(you)較(jiao)大的(de)抗變形和抗沉降能(neng)力(li),特(te)別(bie)適合于軟土(tu)、膨脹土(tu)、濕陷(xian)性黃土(tu)等地(di)基承載力(li)較(jiao)低(di)地(di)區和地(di)震多發地(di)區

涵洞兩(liang)側經(jing)過低洼積(ji)水(shui)地帶時.需要(yao)先設置圍堰(yan)、抽排積(ji)水(shui),必要(yao)時還需要(yao)清除(chu)換(huan)填部(bu)分(fen)淤(yu)泥(ni)。泥(ni)石流(liu)堆積(ji)扇或(huo)分(fen)泌砂(sha)石流(liu)量大、流(liu)速高的區段。這些區段泥(ni)砂(sha)或(huo)砂(sha)石的沖刷將形成對防腐材料或(huo)鋼結構的腐蝕,規(gui)劃時應予以(yi)注(zhu)重,必要(yao)時應對于具體情況進(jin)行(xing)防腐獨(du)立規(gui)劃;部(bu)分(fen)區段能夠存在淤(yu)積(ji)等(deng),采用鋼波紋涵管洞應思考該(gai)疑(yi)問。

由于(yu)(yu)金(jin)屬(shu)波紋(wen)(wen)涵(han)管(guan)施(shi)工(gong)(gong)(gong)簡單且施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期(qi)短(duan)(一(yi)般一(yi)道涵(han)洞的施(shi)工(gong)(gong)(gong)時間在一(yi)個工(gong)(gong)(gong)作日以內(nei)),減短(duan)了多(duo)年凍(dong)土(tu)的裸(luo)露時間,凍(dong)融(rong)量小,故特別適用于(yu)(yu)多(duo)年凍(dong)土(tu)地區。金(jin)屬(shu)波紋(wen)(wen)涵(han)管(guan)施(shi)工(gong)(gong)(gong)時對環境的破壞小,適用于(yu)(yu)生(sheng)態環境脆弱的地區。高速公路重(zhong)要(yao)路段(duan)或保(bao)護艱難路段(duan)。

波(bo)紋(wen)涵管(guan)洞為鋼(gang)(gang)結構,必定存(cun)(cun)在腐蝕的威脅,高(gao)速公路(lu)對路(lu)基(ji)和涵洞的壽數周期需求較高(gao),因(yin)而有必要思考(kao)防腐維護(hu),在維護(hu)辦(ban)理艱難路(lu)段應慎(shen)重使(shi)用(yong)。因(yin)為鋼(gang)(gang)波(bo)紋(wen)涵管(guan)洞存(cun)(cun)在必定的使(shi)用(yong)壽數周期,在高(gao)速公路(lu)的一些重要路(lu)段應慎(shen)重思考(kao)其效勞壽數或改建的便利等(deng)。(hanihanbj.com
