各管節(jie)面流水坡度安(an)(an)裝(zhuang)平順(shun),管節(jie)必需墊(dian)穩坐實,管道(dao)內不得遺留土壤等雜物。每安(an)(an)裝(zhuang)兩節(jie)進(jin)行(xing)一(yi)次管節(jie)的圓度和位(wei)(wei)置校正(zheng)。如泛(fan)起偏位(wei)(wei),采用(yong)千斤頂(ding)在偏位(wei)(wei)的方向(xiang)向(xiang)上頂(ding)管節(jie)進(jin)行(xing)糾偏。

鑲石棉(mian)墊(dian)(dian),因為(wei)現(xian)場地勢等(deng)原(yuan)因,有時相鄰兩法(fa)蘭(lan)之(zhi)間(jian)間(jian)距較小(xiao),這時用(yong)手(shou)錘、鑿(zao)子把(ba)兩法(fa)蘭(lan)之(zhi)間(jian)鑿(zao)開大約1cm的縫隙,用(yong)螺絲刀把(ba)石棉(mian)墊(dian)(dian)鑲在兩法(fa)蘭(lan)之(zhi)間(jian),有時管子頂(ding)部(bu)兩法(fa)蘭(lan)間(jian)距較大,石棉(mian)墊(dian)(dian)鑲嵌難題,用(yong)綁絲把(ba)石棉(mian)墊(dian)(dian)綁在螺栓(shuan)上固定,然后工人開始對稱鎖緊螺絲。直至從外(wai)觀看兩法(fa)蘭(lan)之(zhi)間(jian)只有2—3mm的縫隙即可。

鋼(gang)制波紋管(guan)(guan)(guan)涵(han)(han)管(guan)(guan)(guan)身安(an)裝(zhuang)(zhuang)前,要(yao)檢查涵(han)(han)管(guan)(guan)(guan)底部基(ji)(ji)(ji)礎平(ping)整度(du)(du)、水平(ping)、標(biao)高;確定涵(han)(han)洞位(wei)置(zhi)、中(zhong)(zhong)(zhong)央(yang)軸(zhou)線、中(zhong)(zhong)(zhong)點。連接安(an)裝(zhuang)(zhuang)鋼(gang)制波紋管(guan)(guan)(guan),根(gen)據涵(han)(han)洞實際情況,排放涵(han)(han)管(guan)(guan)(guan)。假如(ru)涵(han)(han)洞兩(liang)側(ce)(ce)進出(chu)水口是與路基(ji)(ji)(ji)同(tong)坡度(du)(du)的斜口形式,安(an)裝(zhuang)(zhuang)時(shi)先(xian)安(an)裝(zhuang)(zhuang)中(zhong)(zhong)(zhong)間(jian)(jian)管(guan)(guan)(guan)節(jie),在基(ji)(ji)(ji)礎長度(du)(du)方(fang)向(xiang)留(liu)出(chu)進出(chu)水口的位(wei)置(zhi)。中(zhong)(zhong)(zhong)間(jian)(jian)管(guan)(guan)(guan)節(jie)全(quan)部安(an)裝(zhuang)(zhuang)完畢,校正(zheng)就位(wei)后再安(an)裝(zhuang)(zhuang)兩(liang)側(ce)(ce)進出(chu)水口。安(an)裝(zhuang)(zhuang)時(shi)從一側(ce)(ce)排放根(gen)管(guan)(guan)(guan)節(jie),使(shi)其(qi)管(guan)(guan)(guan)子(zi)中(zhong)(zhong)(zhong)央(yang)和基(ji)(ji)(ji)礎縱向(xiang)中(zhong)(zhong)(zhong)央(yang)線平(ping)行(xing),同(tong)樣把第(di)二根(gen)管(guan)(guan)(guan)放置(zhi)就位(wei),當兩(liang)根(gen)管(guan)(guan)(guan)相鄰法蘭(lan)間(jian)(jian)相距3~5cm的縫隙時(shi),用(yong)小(xiao)撬棍對(dui)準法蘭(lan)上的螺(luo)栓孔,使(shi)其(qi)兩(liang)根(gen)管(guan)(guan)(guan)法蘭(lan)上的螺(luo)栓孔對(dui)正(zheng),這時(shi)從第(di)二節(jie)管(guan)(guan)(guan)的另(ling)一端用(yong)撬杠撬動(dong)管(guan)(guan)(guan)節(jie),使(shi)其(qi)縱向(xiang)平(ping)移,使(shi)兩(liang)法蘭(lan)間(jian)(jian)距在2cm左右(you),然后全(quan)部穿上螺(luo)栓,擰上螺(luo)絲(si),帶平(ping)扣即可。此(ci)后依此(ci)方(fang)式逐(zhu)節(jie)依次(ci)連接,每道涵(han)(han)洞中(zhong)(zhong)(zhong)間(jian)(jian)管(guan)(guan)(guan)節(jie)無先(xian)后次(ci)序(xu),可以隨意(yi)連接。

鍍鋅波紋管涵

鋼波紋涵管是使用波(bo)紋狀(zhuang)管(guan)(guan)或(huo)由(you)波(bo)紋狀(zhuang)板經(jing)由(you)連署、拼裝形成(cheng)(cheng)的一種涵洞方式。波(bo)紋管(guan)(guan)由(you)鋼、鋁(lv)或(huo)分子化(hua)合物(wu)塑料(liao)等材料(liao)制成(cheng)(cheng)。用以代(dai)替圓(yuan)管(guan)(guan)涵、蓋板涵、拱(gong)涵和(he)小橋(qiao)的優質馬(ma)路建筑(zhu)材料(liao)。對馬(ma)路涵洞來說,涵洞的翹棱均(jun)沉降(jiang)是其毀傷(shang)的主要型式之一。

板(ban)(ban)(ban)(ban)的(de)(de)(de)波(bo)形為(wei)進步板(ban)(ban)(ban)(ban)的(de)(de)(de)剛(gang)度,板(ban)(ban)(ban)(ban)的(de)(de)(de)截(jie)面從平板(ban)(ban)(ban)(ban)加工成一定(ding)波(bo)幅的(de)(de)(de)波(bo)外(wai)形,從加工、拼裝及(ji)板(ban)(ban)(ban)(ban)的(de)(de)(de)剛(gang)度要求出發,并參(can)照海內(nei)外(wai)同類(lei)產品的(de)(de)(de)波(bo)形,管直(zhi)徑小于1.5m的(de)(de)(de)波(bo)距(ju)(ju)為(wei)125mm, 波(bo)高(gao)為(wei)25mm;管直(zhi)徑大于1.5m的(de)(de)(de)波(bo)距(ju)(ju)為(wei)200mm,波(bo)高(gao)為(wei)55mm。

板的(de)尺(chi)寸和厚度為便于板的(de)加工制作,結構(gou)的(de)安裝(zhuang)連接,進步板的(de)制作精度,板材的(de)尺(chi)寸宜適應不同管徑的(de)需要(yao),以形成系列化。板的(de)厚度隨結構(gou)跨徑的(de)大(da)小變化,板厚可選用 2.5-8 mm。

鋼(gang)波紋涵管的(de)材(cai)料主要(yao)(yao)有鋼(gang)質波紋板(ban)材(cai)和(he)高強度螺栓連接組成,其(qi)中鋼(gang)質波紋板(ban)材(cai)采(cai)用海內普遍使(shi)用的(de)A3或(huo)Q235- B熱軋鋼(gang)板(ban),鋼(gang)板(ban)的(de)理化(hua)指標要(yao)(yao)求(qiu)(qiu)達到(dao)國際GB700的(de)有關(guan)要(yao)(yao)求(qiu)(qiu)。防腐(fu)方(fang)式:一(yi)般(ban)采(cai)用熱鍍(du)鋅防腐(fu),鍍(du)鋅量(liang)600克(ke)/平方(fang)米,如有特殊要(yao)(yao)求(qiu)(qiu)時(shi),可(ke)進行二次防腐(fu),內外層覆(fu)塑PE或(huo)環氧樹脂。經二次防腐(fu)使(shi)用壽命可(ke)進步50年。
