為(wei)保證(zheng)鋼波紋管的距離和順直,可(ke)(ke)用(yong)鋼筋(jin)支(zhi)架(jia)對波紋管進(jin)行點(dian)焊固定,防止澆(jiao)筑(zhu)砼時左右位移。管道鋪設后,出于(yu)其它原因造成管壁呈現局部損壞,當損壞程度比較小時,可(ke)(ke)經過焊槍修補處理,如(ru)環向、縱(zong)向裂縫小于(yu)管周長的112或孔(kong)徑60mm的情況。
當損壞程(cheng)度大(da)于(yu)這些數據時(shi),宜經過(guo)換波紋管或基(ji)建筑檢查井(jing)、連接井(jing)等修(xiu)補(bu)方法(fa)處(chu)理。雨期時(shi)節應留(liu)意防止(zhi)管材(cai)漂浮、位移等現象,當管道裝置完畢沒有(you)覆土遇到水泡情況(kuang)時(shi),應復測(ce)管底與管中心高(gao)程(cheng),并做好返工處(chu)理辦法(fa)。
鋼波(bo)紋(wen)管(guan)(guan)安置和線盒及預(yu)留(liu)洞處(chu)相協(xie)調,管(guan)(guan)線盒盡可(ke)能安置在管(guan)(guan)間肋的位置。波(bo)紋(wen)管(guan)(guan)運工(gong)作面后,鋪放前(qian)應檢(jian)查管(guan)(guan)材的外(wai)形及管(guan)(guan)端的堵頭封堵是(shi)否嚴(yan)密,對(dui)變形或裂口(kou)處(chu)進行修補。并對(dui)波(bo)紋(wen)管(guan)(guan)的外(wai)形和標準進行檢(jian)查,按標準、型號(hao)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(ju)放(fang)(fang)線(xian)位置(zhi)(zhi)進行(xing)波紋(wen)管(guan)的鋪設(she)裝置(zhi)(zhi),在裝置(zhi)(zhi)過程中(zhong),應在管(guan)頂襯托木板(ban)作(zuo)維(wei)護(hu),不得直接踐踏(ta)波紋(wen)管(guan)。因波紋(wen)管(guan)底(di)(di)(di)部(bu)砼(tong)層(ceng)較薄,在裝置(zhi)(zhi)底(di)(di)(di)部(bu)鋼(gang)筋(jin)(jin)時,有必要安放(fang)(fang)并(bing)固定好墊塊或馬凳筋(jin)(jin),以保證底(di)(di)(di)部(bu)砼(tong)層(ceng)的厚度。
一(yi)般將管(guan)拉結(jie)(jie)錨固在(zai)板(ban)底層鋼筋(jin)上,依據管(guan)徑(jing)巨細(xi),每0.8-1.0米管(guan)長(chang)錨固一(yi)次(ci)鐵絲(si)(si),底筋(jin)的(de)錨固可(ke)別離放(fang)兩條(tiao)通長(chang)鋼筋(jin)做壓筋(jin),然后(hou)用鐵絲(si)(si)將鋼筋(jin)與(yu)模板(ban)支架拉結(jie)(jie)錨緊。壓筋(jin)和拉結(jie)(jie)鐵絲(si)(si)的(de)巨細(xi)、拉結(jie)(jie)錨固距離經核算后(hou)確認或(huo)由設(she)計(ji)院給定(ding)。
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/
