為保證鋼波紋管的距離和順直,可(ke)(ke)用鋼筋支架對(dui)波紋管進(jin)行點焊固定(ding),防止澆筑砼(tong)時左右位移。管道鋪設后,出于(yu)其(qi)它(ta)原因造成(cheng)管壁呈現局(ju)部損壞,當損壞程度比較小時,可(ke)(ke)經過焊槍修(xiu)補處理(li),如(ru)環向、縱(zong)向裂縫小于(yu)管周長的112或(huo)孔徑60mm的情況。
當(dang)損壞程度大于(yu)這些數據時(shi),宜經過換波紋管或基建筑(zhu)檢查井(jing)、連(lian)接井(jing)等修補(bu)方法處理。雨期時(shi)節應留意防止管材漂浮、位移等現象,當(dang)管道裝置(zhi)完畢(bi)沒(mei)有覆土遇(yu)到(dao)水泡情況時(shi),應復(fu)測(ce)管底與管中心高程,并做好返工處理辦法。
鋼波紋(wen)管(guan)(guan)安(an)置和線(xian)(xian)盒(he)及預(yu)留洞處(chu)相協調,管(guan)(guan)線(xian)(xian)盒(he)盡可能(neng)安(an)置在管(guan)(guan)間肋的位置。波紋(wen)管(guan)(guan)運工作面后(hou),鋪(pu)放(fang)前應檢查(cha)(cha)管(guan)(guan)材的外形(xing)及管(guan)(guan)端的堵頭(tou)封堵是否嚴(yan)密,對變形(xing)或裂口處(chu)進(jin)行修補。并對波紋(wen)管(guan)(guan)的外形(xing)和標準(zhun)進(jin)行檢查(cha)(cha),按標準(zhun)、型號分類平臥疊層堆放(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(ju)放線位置(zhi)進行波(bo)(bo)紋(wen)管的(de)鋪設裝置(zhi),在(zai)裝置(zhi)過程中,應(ying)在(zai)管頂襯托木板作維(wei)護(hu),不得(de)直接踐踏波(bo)(bo)紋(wen)管。因波(bo)(bo)紋(wen)管底部(bu)砼(tong)層(ceng)較薄,在(zai)裝置(zhi)底部(bu)鋼筋時,有必要安(an)放并固定好墊塊(kuai)或馬凳筋,以(yi)保(bao)證(zheng)底部(bu)砼(tong)層(ceng)的(de)厚(hou)度。
一般將管拉結(jie)錨(mao)固在板(ban)底(di)層鋼(gang)筋(jin)上,依據管徑(jing)巨細,每(mei)0.8-1.0米(mi)管長(chang)錨(mao)固一次鐵絲(si),底(di)筋(jin)的錨(mao)固可別離放兩條(tiao)通長(chang)鋼(gang)筋(jin)做壓(ya)筋(jin),然后用鐵絲(si)將鋼(gang)筋(jin)與(yu)模板(ban)支(zhi)架拉結(jie)錨(mao)緊。壓(ya)筋(jin)和(he)拉結(jie)鐵絲(si)的巨細、拉結(jie)錨(mao)固距離經(jing)核算后確認或(huo)由設(she)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/
