裝(zhuang)置(zhi)時從(cong)一側(ce)排放根(gen)管(guan)(guan)(guan)節(jie)(jie)(jie),使(shi)(shi)(shi)其管(guan)(guan)(guan)子中(zhong)心和根(gen)底縱(zong)向中(zhong)心線平(ping)行(xing),同樣把第二(er)根(gen)管(guan)(guan)(guan)放置(zhi)就位,當(dang)兩(liang)根(gen)管(guan)(guan)(guan)相(xiang)鄰法蘭(lan)(lan)間相(xiang)距3—5cm的(de)(de)(de)縫隙時,用(yong)小(xiao)撬棍對準法蘭(lan)(lan)上(shang)的(de)(de)(de)螺栓孔,使(shi)(shi)(shi)其兩(liang)根(gen)管(guan)(guan)(guan)法蘭(lan)(lan)上(shang)的(de)(de)(de)螺栓孔對正,這時從(cong)第二(er)節(jie)(jie)(jie)管(guan)(guan)(guan)的(de)(de)(de)另一端(duan)用(yong)撬杠撬動管(guan)(guan)(guan)節(jie)(jie)(jie),使(shi)(shi)(shi)其縱(zong)向平(ping)移,使(shi)(shi)(shi)兩(liang)法蘭(lan)(lan)間距在2cm左右,然后全部穿上(shang)螺栓,擰上(shang)螺絲,帶(dai)平(ping)扣即可。爾后依此方式逐節(jie)(jie)(jie)依次銜接,每道涵洞中(zhong)間管(guan)(guan)(guan)節(jie)(jie)(jie)無先后次序(xu),能夠隨意銜接。現場裝(zhuang)置(zhi)便當(dang),不需運用(yong)大(da)型(xing)設備。
鋼波紋涵管(guan)施(shi)工技術不可(ke)忽視!
鋼波紋涵管應用(yong)于(yu)新建(jian)公(gong)路工程時,在定購涵管(guan)的(de)(de)同時可抓緊根底資料的(de)(de)備料和基坑(keng)的(de)(de)開挖工作(zuo)。管(guan)壁(bi)(bi)內(nei)外(wai)防(fang)滲(shen)處(chu)置(zhi):管(guan)壁(bi)(bi)內(nei)外(wai)涂乳化(hua)瀝青(qing)或熱瀝青(qing)兩道,從外(wai)觀看(kan)守壁(bi)(bi)內(nei)外(wai)平均的(de)(de)涂成(cheng)了黑管(guan)即可。普通瀝青(qing)涂層(ceng)的(de)(de)厚度要(yao)到達(da)1mm。
金屬波紋涵(han)(han)管應用于公路養護(hu)工(gong)程時,待涵(han)(han)身及洞(dong)口主(zhu)體部件運至施工(gong)現(xian)場后,施工(gong)單位才干開(kai)(kai)端撤除舊涵(han)(han)洞(dong)的工(gong)作(zuo),在撤除舊涵(han)(han)洞(dong)的同時,抓緊根底資料(liao)的備料(liao)工(gong)作(zuo),備料(liao)完成(cheng),并經檢驗合格前方(fang)可停止基(ji)坑(keng)的開(kai)(kai)挖工(gong)作(zuo)。
鋼(gang)波紋涵(han)管施工流程
特別值得(de)留意的是,在(zai)(zai)面對暴雨招致(zhi)的城市內澇問(wen)題時,美國的處(chu)理計(ji)劃就(jiu)是采(cai)取由CSP資料建成的公(gong)開雨水搜集和釋放系(xi)(xi)統(tong)(tong)。這種系(xi)(xi)統(tong)(tong)在(zai)(zai)美國作(zuo)為(wei)停車場、公(gong)園、體育場館、路(lu)堤、雨水淤(yu)積帶、洪泛(fan)區、排水渠(qu)、洼地等商業、公(gong)共和民用建筑、公(gong)路(lu)設備的輔助系(xi)(xi)統(tong)(tong),得(de)到了大(da)范圍推行。
波紋涵管硬(ying)度(du)(du)也是資料(liao)重要(yao)的(de)(de)(de)力(li)學性(xing)能指(zhi)標,硬(ying)度(du)(du)和強度(du)(du)一樣,都反映了資料(liao)對塑性(xing)變(bian)形(xing)的(de)(de)(de)抗力(li),硬(ying)度(du)(du)實驗辦(ban)法(fa)較簡單,又不損壞零件,故在(zai)消費理論(lun)中常常經過測定資料(liao)的(de)(de)(de)硬(ying)度(du)(du)來預算其強度(du)(du)指(zhi)標。波紋涵管硬(ying)度(du)(du)還影響到資料(liao)的(de)(de)(de)耐(nai)磨性(xing),在(zai)普通(tong)狀況下,硬(ying)度(du)(du)高時其耐(nai)磨性(xing)能也較好(hao)。
用千(qian)斤(jin)頂校正整(zheng)道(dao)涵(han)管,使(shi)其中(zhong)(zhong)(zhong)心在所(suo)規(gui)則的中(zhong)(zhong)(zhong)心線上。(構(gou)造受力狀況(kuang)合(he)理,荷載散(san)布(bu)平(ping)均(jun),并有一定(ding)的抗變(bian)形才能。檢查涵(han)管底部根(gen)底平(ping)整(zheng)度、程度、標高;核(he)對土建基準(zhun),肯定(ding)涵(han)洞位(wei)置、中(zhong)(zhong)(zhong)心軸(zhou)線、中(zhong)(zhong)(zhong)點。停止工(gong)廠集(ji)中(zhong)(zhong)(zhong)化消費,消費不受環境影響(xiang),有利降低本錢、控制質量。
銜接裝(zhuang)置(zhi)(zhi)波(bo)紋管:依據涵洞(dong)實踐狀(zhuang)況(kuang),排放涵管。假(jia)如涵洞(dong)兩(liang)側進(jin)出(chu)(chu)水口(kou)是(shi)與路基同坡度的(de)斜口(kou)方(fang)式,裝(zhuang)置(zhi)(zhi)時先(xian)裝(zhuang)置(zhi)(zhi)中(zhong)間管節,在(zai)根底長度方(fang)向(xiang)留(liu)出(chu)(chu)進(jin)出(chu)(chu)水口(kou)的(de)位置(zhi)(zhi)。中(zhong)間管節全部裝(zhuang)置(zhi)(zhi)終(zhong)了,校正就位后再裝(zhuang)置(zhi)(zhi)兩(liang)側進(jin)出(chu)(chu)水口(kou)。
鋼(gang)波紋涵管(guan)的優點處理北方冰(bing)冷地域(yu)(霜凍)對橋梁和管(guan)涵砼構造的毀壞問題。采用規(gui)范化設計(ji),消費、設計(ji)簡單,消費周期短。減少或基(ji)本舍棄了常規(gui)建材,如(ru)水泥、黃砂、石(shi)子、木材的運(yun)用,環保意義深遠(yuan)。鑲石(shi)棉(mian)(mian)墊(dian):由于(yu)現場(chang)地勢等緣由,有(you)時相鄰(lin)兩法(fa)蘭(lan)之間(jian)(jian)(jian)間(jian)(jian)(jian)距較(jiao)小,這時用手錘、鑿(zao)子把兩法(fa)蘭(lan)之間(jian)(jian)(jian)鑿(zao)開(kai)大約1cm的縫隙,用螺(luo)絲刀把石(shi)棉(mian)(mian)墊(dian)鑲在兩法(fa)蘭(lan)之間(jian)(jian)(jian),有(you)時管(guan)子頂部兩法(fa)蘭(lan)間(jian)(jian)(jian)距較(jiao)大,石(shi)棉(mian)(mian)墊(dian)鑲嵌艱(jian)難(nan),用綁(bang)絲把石(shi)棉(mian)(mian)墊(dian)綁(bang)在螺(luo)栓(shuan)上固(gu)定,然后工人開(kai)端(duan)對稱鎖緊螺(luo)絲。
直(zhi)至從外觀(guan)看兩(liang)法蘭之間只要2—3mm的(de)(de)縫隙即可。施工(gong)(gong)工(gong)(gong)期短是明顯的(de)(de)優勢,土建工(gong)(gong)程與管節裝置可分開施行(xing),然(ran)后停(ting)止(zhi)整體拼裝。順(shun)應(ying)地基變形才能強,對地基承載才能、平整度請求較低,工(gong)(gong)程實踐造價比同類跨徑的(de)(de)橋、涵洞相(xiang)近(jin)或(huo)較低。(hanihanbj.com)
