裝(zhuang)置時從(cong)一側排放(fang)根(gen)(gen)(gen)管(guan)(guan)(guan)節(jie)(jie),使(shi)其(qi)(qi)管(guan)(guan)(guan)子(zi)中(zhong)(zhong)心和根(gen)(gen)(gen)底(di)縱(zong)向(xiang)中(zhong)(zhong)心線平(ping)行,同樣把第(di)二根(gen)(gen)(gen)管(guan)(guan)(guan)放(fang)置就位,當兩(liang)根(gen)(gen)(gen)管(guan)(guan)(guan)相鄰法蘭間(jian)相距(ju)3—5cm的(de)縫隙時,用小撬(qiao)(qiao)棍對準法蘭上的(de)螺(luo)(luo)栓孔,使(shi)其(qi)(qi)兩(liang)根(gen)(gen)(gen)管(guan)(guan)(guan)法蘭上的(de)螺(luo)(luo)栓孔對正,這(zhe)時從(cong)第(di)二節(jie)(jie)管(guan)(guan)(guan)的(de)另一端用撬(qiao)(qiao)杠撬(qiao)(qiao)動管(guan)(guan)(guan)節(jie)(jie),使(shi)其(qi)(qi)縱(zong)向(xiang)平(ping)移,使(shi)兩(liang)法蘭間(jian)距(ju)在(zai)2cm左(zuo)右,然后(hou)全部穿上螺(luo)(luo)栓,擰上螺(luo)(luo)絲,帶平(ping)扣即可。爾后(hou)依此方式逐節(jie)(jie)依次(ci)銜(xian)(xian)接(jie),每道涵洞(dong)中(zhong)(zhong)間(jian)管(guan)(guan)(guan)節(jie)(jie)無先(xian)后(hou)次(ci)序,能(neng)夠隨意銜(xian)(xian)接(jie)。現場裝(zhuang)置便當,不(bu)需運用大型設備(bei)。
鋼波紋涵(han)管施工技術不可忽視!
鋼波紋涵管應用于(yu)新建公路工程時(shi),在定(ding)購涵(han)管(guan)(guan)的同時(shi)可抓緊根底資(zi)料(liao)的備料(liao)和基坑的開(kai)挖工作。管(guan)(guan)壁(bi)內外(wai)防滲處(chu)置:管(guan)(guan)壁(bi)內外(wai)涂(tu)(tu)乳化瀝青或熱(re)瀝青兩道,從(cong)外(wai)觀看守(shou)壁(bi)內外(wai)平均的涂(tu)(tu)成(cheng)了黑管(guan)(guan)即可。普通瀝青涂(tu)(tu)層的厚度要到達1mm。
金屬波紋涵管(guan)應(ying)用于公路養護工(gong)程時(shi),待(dai)涵身及(ji)洞(dong)口主(zhu)體(ti)部件運(yun)至施工(gong)現(xian)場后,施工(gong)單(dan)位才(cai)干(gan)開端撤除舊涵洞(dong)的工(gong)作,在(zai)撤除舊涵洞(dong)的同時(shi),抓緊(jin)根底資料(liao)的備料(liao)工(gong)作,備料(liao)完成,并(bing)經檢驗合格前方可停止(zhi)基坑(keng)的開挖工(gong)作。
鋼波紋涵管施工(gong)流程
特別(bie)值(zhi)得(de)留意的是(shi),在面對(dui)暴雨(yu)招致的城(cheng)市內(nei)澇問題(ti)時(shi),美(mei)國的處理(li)計劃就是(shi)采(cai)取由CSP資(zi)料建成的公(gong)(gong)開雨(yu)水搜(sou)集(ji)和(he)釋放系(xi)統。這種系(xi)統在美(mei)國作為(wei)停車場、公(gong)(gong)園(yuan)、體育場館、路堤、雨(yu)水淤積帶、洪泛區、排水渠、洼地(di)等商(shang)業、公(gong)(gong)共和(he)民用建筑(zhu)、公(gong)(gong)路設備的輔助(zhu)系(xi)統,得(de)到了大范圍推行。
波(bo)紋涵管(guan)硬(ying)度(du)也(ye)是資料(liao)重要的(de)(de)(de)力學性能指(zhi)標(biao),硬(ying)度(du)和強度(du)一樣,都反映(ying)了資料(liao)對(dui)塑性變形的(de)(de)(de)抗力,硬(ying)度(du)實驗辦法(fa)較(jiao)簡單,又不損(sun)壞零件,故(gu)在消費理論中常(chang)(chang)常(chang)(chang)經過測(ce)定資料(liao)的(de)(de)(de)硬(ying)度(du)來預算其(qi)強度(du)指(zhi)標(biao)。波(bo)紋涵管(guan)硬(ying)度(du)還影響(xiang)到(dao)資料(liao)的(de)(de)(de)耐(nai)磨性,在普通狀(zhuang)況下,硬(ying)度(du)高(gao)時其(qi)耐(nai)磨性能也(ye)較(jiao)好。
用千(qian)斤頂(ding)校(xiao)正整道涵管,使其(qi)中(zhong)心(xin)在所(suo)規則的中(zhong)心(xin)線上(shang)。(構造受(shou)力狀(zhuang)況合(he)理(li),荷載散布平均,并(bing)有一定的抗變形才(cai)能。檢查涵管底部根底平整度(du)、程度(du)、標高;核對土建(jian)基準,肯定涵洞位置、中(zhong)心(xin)軸線、中(zhong)點。停(ting)止工廠集(ji)中(zhong)化消(xiao)費(fei),消(xiao)費(fei)不受(shou)環(huan)境影響(xiang),有利降低(di)本錢、控制質(zhi)量。
銜接裝置(zhi)波紋管(guan):依據涵洞(dong)實踐狀況,排放涵管(guan)。假如涵洞(dong)兩側進(jin)(jin)出(chu)水口是(shi)與路基同(tong)坡(po)度(du)的(de)斜口方式,裝置(zhi)時(shi)先裝置(zhi)中(zhong)間管(guan)節,在(zai)根底長度(du)方向留(liu)出(chu)進(jin)(jin)出(chu)水口的(de)位(wei)置(zhi)。中(zhong)間管(guan)節全部裝置(zhi)終了,校正就位(wei)后再裝置(zhi)兩側進(jin)(jin)出(chu)水口。
鋼波紋涵管(guan)的(de)(de)優點處理北方冰冷地域(霜(shuang)凍)對(dui)橋梁和管(guan)涵砼構造(zao)的(de)(de)毀壞問題。采(cai)用(yong)(yong)規(gui)范化設(she)計,消(xiao)費(fei)、設(she)計簡單(dan),消(xiao)費(fei)周期(qi)短。減(jian)少或基本舍棄了常規(gui)建材(cai),如水泥(ni)、黃砂、石(shi)(shi)子(zi)、木材(cai)的(de)(de)運用(yong)(yong),環(huan)保意義深(shen)遠。鑲石(shi)(shi)棉墊(dian):由(you)于現場地勢等(deng)緣由(you),有(you)時(shi)相鄰(lin)兩(liang)法蘭(lan)之(zhi)間(jian)間(jian)距(ju)較小,這時(shi)用(yong)(yong)手(shou)錘、鑿子(zi)把兩(liang)法蘭(lan)之(zhi)間(jian)鑿開大約1cm的(de)(de)縫隙,用(yong)(yong)螺(luo)絲刀把石(shi)(shi)棉墊(dian)鑲在兩(liang)法蘭(lan)之(zhi)間(jian),有(you)時(shi)管(guan)子(zi)頂部兩(liang)法蘭(lan)間(jian)距(ju)較大,石(shi)(shi)棉墊(dian)鑲嵌艱難,用(yong)(yong)綁(bang)絲把石(shi)(shi)棉墊(dian)綁(bang)在螺(luo)栓上固(gu)定,然后工人(ren)開端對(dui)稱鎖緊螺(luo)絲。
直至從外觀看兩法蘭(lan)之間只要2—3mm的(de)縫隙即可(ke)。施工(gong)(gong)工(gong)(gong)期(qi)短是明顯的(de)優(you)勢,土(tu)建工(gong)(gong)程(cheng)與(yu)管節(jie)裝置可(ke)分開施行(xing),然后停止整體拼裝。順(shun)應地(di)基變形才能強,對地(di)基承(cheng)載才能、平整度請求較低,工(gong)(gong)程(cheng)實(shi)踐造價比(bi)同(tong)類(lei)跨徑(jing)的(de)橋(qiao)、涵洞(dong)相近或較低。(hanihanbj.com)
