拼接型鋼波紋涵管的誕生大大提高的運輸效率

大規模基礎建設拉動內需,帶來公(gong)路(lu)、鐵路(lu)、水利等鋼(gang)質波紋管(guan)傳統(tong)應(ying)用領(ling)域(yu)(yu)的(de)剛性需求;應(ying)用技(ji)術日漸(jian)成熟帶來的(de)應(ying)用領(ling)域(yu)(yu)擴(kuo)展,如在國外已普遍應(ying)用的(de)各種產業項目的(de)內部(bu)管(guan)網(wang)、礦(kuang)山、倉儲、水利舉措措施等領(ling)域(yu)(yu);勞動力(li)本錢和傳統(tong)建筑(zhu)材料本錢上(shang)(shang)升(sheng)將(jiang)進步鋼(gang)質波紋管(guan)的(de)競爭上(shang)(shang)風;環(huan)保(bao)意識的(de)增強和水土保(bao)持要求的(de)進步,將(jiang)帶來更加的(de)應(ying)用。

近年(nian)來,鋼波紋(wen)涵管需求量大幅增加。跟著我國鋼制波紋(wen)管相關應(ying)用研究(jiu)和各(ge)行業(ye)應(ying)用尺度和規范不斷完善,未(wei)來鋼波紋(wen)涵管需求將大幅增長(chang)。其(qi)原因包(bao)括以下四方面:

有沖洗(xi)的涵(han)洞(dong)(dong)進出口應根據需(xu)要設置相(xiang)應的調治構筑物,同時洞(dong)(dong)口應按(an)地形前(qian)提作必要的處理,防(fang)止洞(dong)(dong)口受(shou)沖洗(xi),影(ying)響(xiang)涵(han)洞(dong)(dong)的泄水能力。

涵洞兩側(ce)經由(you)低洼(wa)積水(shui)地(di)帶時.需要(yao)先設置圍(wei)堰、抽排積水(shui),必要(yao)時還需要(yao)清(qing)除換填部門淤泥。進(jin)出(chu)(chu)口(kou)(kou)可(ke)采(cai)(cai)(cai)用由(you)制造(zao)的(de)金屬(shu)波紋(wen)管節,有直管和(he)與路基邊坡(po)(po)同坡(po)(po)率的(de)斜口(kou)(kou)兩種形式;也可(ke)根據所在地(di)區的(de)詳細情(qing)況采(cai)(cai)(cai)用漿(jiang)(jiang)砌(qi)(qi)(qi)(qi)片(pian)(pian)石(shi)或(huo)干砌(qi)(qi)(qi)(qi)片(pian)(pian)石(shi)砌(qi)(qi)(qi)(qi)筑。一(yi)般在嚴(yan)寒(han)地(di)區,采(cai)(cai)(cai)用金屬(shu)波紋(wen)管節或(huo)干砌(qi)(qi)(qi)(qi)片(pian)(pian)石(shi)。在其與河床接頭處進(jin)出(chu)(chu)口(kou)(kou)地(di)面及邊坡(po)(po)一(yi)定范圍(wei)內(nei)應設置雙(shuang)層漿(jiang)(jiang)砌(qi)(qi)(qi)(qi)片(pian)(pian)石(shi)或(huo)干砌(qi)(qi)(qi)(qi)片(pian)(pian)石(shi)鋪砌(qi)(qi)(qi)(qi),以防止(zhi)沖洗(xi),并作必要(yao)的(de)防滲處理;為防止(zhi)路基土堵(du)塞涵洞洞口(kou)(kou),在洞口(kou)(kou)與路堤交匯處做一(yi)定高度(du)(du)和(he)厚度(du)(du)的(de)漿(jiang)(jiang)砌(qi)(qi)(qi)(qi)片(pian)(pian)石(shi)或(huo)干砌(qi)(qi)(qi)(qi)片(pian)(pian)石(shi)墻(也可(ke)采(cai)(cai)(cai)用鉛(qian)絲石(shi)籠)防護。

鋼波紋涵管應用于(yu)公路養護(hu)工(gong)(gong)(gong)(gong)程(cheng)時(shi)(shi),待涵(han)(han)身及洞口主(zhu)體部(bu)件(jian)運(yun)至施工(gong)(gong)(gong)(gong)現(xian)場后,施工(gong)(gong)(gong)(gong)單位(wei)才能開始拆除舊(jiu)涵(han)(han)洞的工(gong)(gong)(gong)(gong)作,在拆除舊(jiu)涵(han)(han)洞的同時(shi)(shi),抓緊基(ji)礎材(cai)料(liao)(liao)的備(bei)料(liao)(liao)工(gong)(gong)(gong)(gong)作,備(bei)料(liao)(liao)完成,并經檢修合格(ge)后方(fang)可進(jin)行基(ji)坑的開挖(wa)工(gong)(gong)(gong)(gong)作。金屬(shu)波紋涵(han)(han)管應用于(yu)新建公路工(gong)(gong)(gong)(gong)程(cheng)時(shi)(shi),在定(ding)購涵(han)(han)管的同時(shi)(shi)可抓緊基(ji)礎材(cai)料(liao)(liao)的備(bei)料(liao)(liao)和基(ji)坑的開挖(wa)工(gong)(gong)(gong)(gong)作。
