為保(bao)證鋼波紋管的距離(li)和(he)順(shun)直,可用鋼筋支架(jia)對波(bo)紋(wen)管(guan)進行點焊固定,防止澆筑砼時(shi)(shi)左(zuo)右位移(yi)。管(guan)道鋪(pu)設后,出(chu)于其它原因造成(cheng)管(guan)壁(bi)呈現局部損壞,當損壞程(cheng)度比較小時(shi)(shi),可經過(guo)焊槍修(xiu)補處理(li),如(ru)環向、縱向裂縫小于管(guan)周長的112或孔徑60mm的情況(kuang)。
當(dang)損壞(huai)程度(du)大于這些數據(ju)時(shi),宜(yi)經過換波紋管(guan)或基建筑(zhu)檢查(cha)井、連(lian)接井等(deng)修(xiu)補方(fang)法處理。雨期時(shi)節應留意防止管(guan)材漂浮、位移等(deng)現象(xiang),當(dang)管(guan)道裝置完畢沒有覆土遇到水泡(pao)情況時(shi),應復測(ce)管(guan)底(di)與管(guan)中(zhong)心高程,并(bing)做(zuo)好返(fan)工處理辦法。
鋼波紋管(guan)(guan)安置(zhi)和(he)線盒(he)及(ji)預留洞處(chu)相協調,管(guan)(guan)線盒(he)盡可能安置(zhi)在管(guan)(guan)間肋的位(wei)置(zhi)。波紋管(guan)(guan)運(yun)工作面后,鋪放(fang)前應(ying)檢(jian)(jian)查管(guan)(guan)材的外形及(ji)管(guan)(guan)端(duan)的堵頭封堵是否嚴密(mi),對(dui)變形或裂(lie)口處(chu)進行修補。并對(dui)波紋管(guan)(guan)的外形和(he)標準進行檢(jian)(jian)查,按標準、型號(hao)分類平臥疊層堆放(fang)。
The placement of steel bellows shall be coordinated with wire box and reserved hole, and the wire box shall be placed at the position of ribs between pipes as far as possible. After the corrugated pipe is transported to the working face, the shape of the pipe and the sealing of the plug at the pipe end should be checked before laying, and the deformation or crack should be repaired. Check the shape and standard of the bellows, and stack them horizontally according to the standard and model.
依據放線位置進行(xing)波(bo)紋管(guan)的鋪設裝(zhuang)置,在(zai)(zai)裝(zhuang)置過程中(zhong),應在(zai)(zai)管(guan)頂襯托木(mu)板作(zuo)維護,不得直(zhi)接踐踏波(bo)紋管(guan)。因波(bo)紋管(guan)底(di)部砼層(ceng)較(jiao)薄,在(zai)(zai)裝(zhuang)置底(di)部鋼筋(jin)時,有必(bi)要安放并固定(ding)好墊塊或馬凳筋(jin),以(yi)保證底(di)部砼層(ceng)的厚(hou)度。
一般將管(guan)(guan)拉結(jie)錨(mao)固(gu)在(zai)板底層鋼筋(jin)(jin)上,依(yi)據管(guan)(guan)徑巨細,每0.8-1.0米管(guan)(guan)長錨(mao)固(gu)一次(ci)鐵絲,底筋(jin)(jin)的錨(mao)固(gu)可別(bie)離(li)放兩(liang)條通(tong)長鋼筋(jin)(jin)做壓筋(jin)(jin),然后用鐵絲將鋼筋(jin)(jin)與模板支架(jia)拉結(jie)錨(mao)緊。壓筋(jin)(jin)和(he)拉結(jie)鐵絲的巨細、拉結(jie)錨(mao)固(gu)距離(li)經核算后確認或由設計院給定。
在管材放入溝槽時,應依據施工設備、溝槽以及管徑巨細,且鄙人管過程中應留意不得與溝壁、溝底呈現劇烈磕碰現象,宜經過適宜的吊車等機械平穩下溝,一起吊裝時不得呈現穿心吊,應少有兩個支撐吊點。為防止澆筑砼時波紋管上浮,將波紋管拉結錨固。//hanihanbj.com/
