為什么說鋼波紋涵管的施工不受季節限制

材料要(yao)(yao)求(qiu)(qiu) 基礎(chu)材料要(yao)(yao)求(qiu)(qiu) 普通土(tu)地(di)(di)段,因為(wei)金屬波紋涵(han)管(guan)為(wei)金屬結構,其適應變形能力較強(qiang),采取砂(sha)(sha)礫(li)基礎(chu),基礎(chu)厚度(du)≥0.6m,以知足施(shi)工的(de)(de)(de)壓(ya)實(shi)要(yao)(yao)求(qiu)(qiu)、填(tian)料小(xiao)強(qiang)度(du)要(yao)(yao)求(qiu)(qiu)、更大(da)粒徑要(yao)(yao)乞降地(di)(di)基基礎(chu)的(de)(de)(de)抗(kang)凍(dong)(dong)要(yao)(yao)求(qiu)(qiu)。換填(tian)深(shen)度(du)一(yi)般(ban)(ban)根據當地(di)(di)凍(dong)(dong)深(shen)等確定。設(she)置構造物(wu)地(di)(di)基要(yao)(yao)盡可能避(bi)開柔軟層與巖石(shi)的(de)(de)(de)接壤處(chu),當無法避(bi)開時(shi),柔軟區間要(yao)(yao)用級配(pei)良(liang)好的(de)(de)(de)砂(sha)(sha)礫(li)仔細夯實(shi)(厚度(du)大(da)于0.6m),巖石(shi)區應開挖至少(shao)0.3m后用砂(sha)(sha)礫(li)松(song)鋪(pu),以減小(xiao)相(xiang)對變位。考慮到地(di)(di)下(xia)水及其影(ying)響,建議在非凍(dong)(dong)地(di)(di)區也采用砂(sha)(sha)礫(li)基礎(chu)。一(yi)般(ban)(ban),在某些地(di)(di)區砂(sha)(sha)礫(li)材料稀少(shao)或砂(sha)(sha)礫(li)級配(pei)較差時(shi),也可換填(tian)碎石(shi)、礫(li)石(shi)或河(山)砂(sha)(sha)及碎石(shi)土(tu),但應知足壓(ya)實(shi)要(yao)(yao)求(qiu)(qiu)、填(tian)料小(xiao)強(qiang)度(du)要(yao)(yao)求(qiu)(qiu)、更大(da)粒徑要(yao)(yao)乞降抗(kang)凍(dong)(dong)要(yao)(yao)求(qiu)(qiu)。      

金屬鋼波紋涵管的(de)施(shi)工不(bu)受季節(jie)限制,一(yi)年(nian)中四個季節(jie)都可以(yi)安裝使用(yong),而且所(suo)用(yong)時(shi)間短(duan)。防侵蝕(shi)要求。金(jin)屬(shu)波紋涵管(guan)材料均(jun)為金(jin)屬(shu),購(gou)置的(de)管(guan)節(jie)和連接螺栓等均(jun)采(cai)用(yong)熱浸(jin)鍍鋅防腐處理,其厚度大于或即是84微米。此外在現場施(shi)工增涂(tu)瀝(li)青涂(tu)層。      

以上紹介金屬波紋(wen)涵管動(dong)工技術,期望給大家帶來更多(duo)的(de)幫忙,如果(guo)需求更多(duo)的(de)信息(xi),可以的(de)電(dian)話到(dao)我企(qi)業咨詢(xun)。

以為(wei)合(he)(he)適(shi)而使(shi)用(yong)的(de)金屬波紋涵管歸屬柔(rou)性結(jie)構,準許涵管縱向(xiang)沉(chen)降變(bian)型(xing),對地基的(de)承載力要求較(jiao)低,無須對地基施(shi)行(xing)(xing)換填處(chu)置(zhi)。以為(wei)合(he)(he)適(shi)而使(shi)用(yong)金屬波紋涵管結(jie)構,管身(shen)上部填土(tu)厚度是(shi)逐(zhu)漸變(bian)化的(de),防(fang)止了由突變(bian)而引動的(de)跳車現象,也防(fang)止了對建構物的(de)毀壞。管體的(de)生(sheng)產由化工(gong)廠實行(xing)(xing),不(bu)受在場背景的(de)影響,因此(ci)防(fang)止了卑劣(lie)景象形象對工(gong)程(cheng)進程(cheng)度的(de)影響,有匡(kuang)助于扼制工(gong)程(cheng)品質。

馬(ma)路工(gong)(gong)程的涵洞(dong)普通以(yi)為合適(shi)而使用鋼筋水(shui)泥制造,現以(yi)為合適(shi)而使用金屬波紋涵管接(jie)替(ti)鋼筋混凝 土(tu)施行(xing)涵洞(dong)動工(gong)(gong),這(zhe)在(zai)海內是一項新技術,下邊采編給大家紹(shao)介金屬波紋涵管動工(gong)(gong)有哪一些技術。
