為保證鋼波紋管的距離和順(shun)直,可用鋼(gang)筋支架對波紋管(guan)(guan)(guan)進行點焊(han)固定(ding),防止澆筑砼(tong)時左右位移。管(guan)(guan)(guan)道鋪(pu)設后,出于(yu)其它(ta)原因造成管(guan)(guan)(guan)壁(bi)呈(cheng)現局部損(sun)壞,當損(sun)壞程度比較小時,可經過焊(han)槍修補處(chu)理(li),如環向、縱向裂縫(feng)小于(yu)管(guan)(guan)(guan)周長(chang)的112或孔徑60mm的情況。
當損(sun)壞程(cheng)(cheng)度大于這些(xie)數據時(shi),宜經過換波紋管或(huo)基(ji)建筑檢查井(jing)(jing)、連接井(jing)(jing)等修(xiu)補(bu)方法(fa)處理(li)。雨(yu)期(qi)時(shi)節應留(liu)意防止管材漂(piao)浮、位移等現象,當管道裝置(zhi)完畢沒有(you)覆土(tu)遇到水泡情況時(shi),應復(fu)測管底與(yu)管中(zhong)心高程(cheng)(cheng),并做好返(fan)工處理(li)辦法(fa)。
鋼波紋管(guan)安(an)置和線盒及預留洞(dong)處(chu)相協調,管(guan)線盒盡可能安(an)置在(zai)管(guan)間肋的位(wei)置。波紋管(guan)運工作面后(hou),鋪(pu)放前應檢(jian)查管(guan)材的外形(xing)(xing)(xing)及管(guan)端的堵(du)頭封堵(du)是否嚴(yan)密,對變形(xing)(xing)(xing)或裂(lie)口處(chu)進行修(xiu)補。并對波紋管(guan)的外形(xing)(xing)(xing)和標(biao)準(zhun)(zhun)進行檢(jian)查,按標(biao)準(zhun)(zhun)、型號分類(lei)平臥疊層堆放。
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.
依(yi)據放線位置(zhi)(zhi)進行波(bo)(bo)紋管(guan)的鋪設裝(zhuang)置(zhi)(zhi),在(zai)裝(zhuang)置(zhi)(zhi)過(guo)程中,應在(zai)管(guan)頂襯托(tuo)木板作維(wei)護,不(bu)得直(zhi)接踐踏波(bo)(bo)紋管(guan)。因波(bo)(bo)紋管(guan)底部(bu)(bu)砼層較(jiao)薄,在(zai)裝(zhuang)置(zhi)(zhi)底部(bu)(bu)鋼筋時,有必要安放并固(gu)定好墊塊或馬(ma)凳筋,以保證底部(bu)(bu)砼層的厚度。
一般(ban)將管拉(la)結(jie)(jie)錨(mao)(mao)固(gu)在板底層鋼筋上,依據管徑巨細,每0.8-1.0米管長錨(mao)(mao)固(gu)一次鐵(tie)絲(si)(si),底筋的(de)錨(mao)(mao)固(gu)可別(bie)離放兩條通(tong)長鋼筋做(zuo)壓筋,然后(hou)用鐵(tie)絲(si)(si)將鋼筋與模板支架(jia)拉(la)結(jie)(jie)錨(mao)(mao)緊。壓筋和拉(la)結(jie)(jie)鐵(tie)絲(si)(si)的(de)巨細、拉(la)結(jie)(jie)錨(mao)(mao)固(gu)距(ju)離經(jing)核算后(hou)確(que)認或由設計院給(gei)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/
