為保(bao)證鋼波紋管的距離和順直，可用鋼筋支架對波(bo)紋管進行(xing)點焊固定，防止澆筑砼時左右位移(yi)。管道(dao)鋪(pu)設后(hou)，出(chu)于其它原因造成管壁呈現局部損(sun)壞，當損(sun)壞程度比較小時，可經過(guo)焊槍(qiang)修補處理，如環向(xiang)(xiang)、縱向(xiang)(xiang)裂縫小于管周(zhou)長的112或(huo)孔徑60mm的情況。

鋼波紋管

當損(sun)壞程度大于這些數據時(shi)，宜經過換波紋管(guan)或基(ji)建筑檢查井(jing)、連接(jie)井(jing)等修補方法處理。雨期時(shi)節(jie)應留意防止管(guan)材(cai)漂浮、位移等現(xian)象，當管(guan)道(dao)裝置(zhi)完畢沒(mei)有(you)覆土(tu)遇(yu)到水泡(pao)情況時(shi)，應復測管(guan)底與管(guan)中心高程，并做好返工(gong)處理辦法。

鋼波(bo)紋管(guan)(guan)(guan)(guan)安置和線盒(he)及(ji)預(yu)留(liu)洞(dong)處(chu)(chu)相協(xie)調，管(guan)(guan)(guan)(guan)線盒(he)盡(jin)可(ke)能(neng)安置在管(guan)(guan)(guan)(guan)間肋的(de)位置。波(bo)紋管(guan)(guan)(guan)(guan)運工作(zuo)面后，鋪放前應檢查(cha)管(guan)(guan)(guan)(guan)材(cai)的(de)外(wai)(wai)形及(ji)管(guan)(guan)(guan)(guan)端的(de)堵頭封堵是否(fou)嚴(yan)密，對(dui)變形或裂口處(chu)(chu)進行修補。并對(dui)波(bo)紋管(guan)(guan)(guan)(guan)的(de)外(wai)(wai)形和標(biao)準進行檢查(cha)，按標(biao)準、型(xing)號分類平臥疊層(ceng)堆放。

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.

鋼波紋管

依據放線位置進行波紋管的(de)鋪設裝(zhuang)置，在裝(zhuang)置過程中，應在管頂襯托木板作維(wei)護(hu)，不(bu)得直接踐踏(ta)波紋管。因(yin)波紋管底(di)部(bu)砼層(ceng)較薄(bo)，在裝(zhuang)置底(di)部(bu)鋼筋時，有必要安(an)放并固定(ding)好墊(dian)塊或馬(ma)凳筋，以保證底(di)部(bu)砼層(ceng)的(de)厚度(du)。

一般將管(guan)(guan)拉結(jie)錨(mao)(mao)(mao)固(gu)在板(ban)底層鋼(gang)(gang)筋(jin)上，依據(ju)管(guan)(guan)徑(jing)巨細，每0.8-1.0米管(guan)(guan)長錨(mao)(mao)(mao)固(gu)一次鐵絲(si)(si)，底筋(jin)的錨(mao)(mao)(mao)固(gu)可別離放兩條(tiao)通長鋼(gang)(gang)筋(jin)做壓筋(jin)，然后(hou)用(yong)鐵絲(si)(si)將鋼(gang)(gang)筋(jin)與(yu)模板(ban)支架拉結(jie)錨(mao)(mao)(mao)緊(jin)。壓筋(jin)和(he)拉結(jie)鐵絲(si)(si)的巨細、拉結(jie)錨(mao)(mao)(mao)固(gu)距離經核算(suan)后(hou)確(que)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/
