鋼波紋涵管

為什么說鋼波紋涵管的施工不受季節限制

材(cai)料要求(qiu)(qiu) 基(ji)礎材(cai)料要求(qiu)(qiu) 普(pu)通土地(di)(di)段,因為(wei)(wei)金屬波紋涵管為(wei)(wei)金屬結構(gou),其適應變形能(neng)力較強,采取砂礫(li)基(ji)礎,基(ji)礎厚度≥0.6m,以知足施工的(de)壓實要求(qiu)(qiu)、填料小強度要求(qiu)(qiu)、更大粒徑要乞(qi)降(jiang)地(di)(di)基(ji)基(ji)礎的(de)抗(kang)凍(dong)要求(qiu)(qiu)。換填深度一般根據(ju)當(dang)地(di)(di)凍(dong)深等確定。設置構(gou)造(zao)物(wu)地(di)(di)基(ji)要盡可能(neng)避開(kai)柔軟層與巖石(shi)(shi)的(de)接壤處(chu),當(dang)無法避開(kai)時,柔軟區(qu)(qu)間(jian)要用(yong)級配良(liang)好的(de)砂礫(li)仔細夯實(厚度大于0.6m),巖石(shi)(shi)區(qu)(qu)應開(kai)挖至少0.3m后(hou)用(yong)砂礫(li)松鋪,以減小相對變位。考慮到(dao)地(di)(di)下水及其影響,建議在(zai)非(fei)凍(dong)地(di)(di)區(qu)(qu)也(ye)采用(yong)砂礫(li)基(ji)礎。一般,在(zai)某些(xie)地(di)(di)區(qu)(qu)砂礫(li)材(cai)料稀少或(huo)砂礫(li)級配較差時,也(ye)可換填碎石(shi)(shi)、礫(li)石(shi)(shi)或(huo)河(山)砂及碎石(shi)(shi)土,但(dan)應知足壓實要求(qiu)(qiu)、填料小強度要求(qiu)(qiu)、更大粒徑要乞(qi)降(jiang)抗(kang)凍(dong)要求(qiu)(qiu)。      

金屬鋼波紋涵管的施工(gong)不受季節(jie)限(xian)制,一年中四(si)個季節(jie)都可以安裝使用,而且所(suo)用時間短。防侵蝕要求(qiu)。金屬(shu)(shu)波(bo)紋涵管材料均(jun)為金屬(shu)(shu),購置的管節(jie)和連接螺栓等均(jun)采(cai)用熱浸(jin)鍍鋅防腐處(chu)理,其厚度大于(yu)或即是84微米。此外在現場(chang)施工(gong)增涂瀝青(qing)涂層。      

以上紹介金屬(shu)波紋涵(han)管動工技術(shu),期(qi)望給大家(jia)帶來更(geng)多(duo)的幫忙,如果需求更(geng)多(duo)的信息,可以的電(dian)話到我企業咨詢(xun)。

鋼波紋涵管

以為(wei)合適而(er)使(shi)用的金屬波紋涵(han)管(guan)歸屬柔性結構(gou),準許涵(han)管(guan)縱向(xiang)沉降(jiang)變型,對地(di)基的承載力要求較低(di),無須對地(di)基施行換填(tian)處(chu)置。以為(wei)合適而(er)使(shi)用金屬波紋涵(han)管(guan)結構(gou),管(guan)身(shen)上部填(tian)土厚度是逐漸變化的,防(fang)止(zhi)了由突變而(er)引(yin)動的跳車現象,也防(fang)止(zhi)了對建構(gou)物的毀壞。管(guan)體的生產由化工廠實行,不受在場背(bei)景的影響,因此防(fang)止(zhi)了卑劣景象形(xing)象對工程進程度的影響,有匡助于扼制工程品(pin)質。

馬路工程的涵(han)洞普通(tong)以為合適而使用鋼筋(jin)水泥(ni)制造,現以為合適而使用金(jin)屬波(bo)紋涵(han)管接替鋼筋(jin)混凝 土施行涵(han)洞動(dong)(dong)工,這在(zai)海內是(shi)一(yi)項新技術(shu),下邊(bian)采(cai)編給大(da)家紹介金(jin)屬波(bo)紋涵(han)管動(dong)(dong)工有(you)哪一(yi)些技術(shu)。
