鋼波紋管涵(han)洞施工以(yi)鋼波(bo)紋(wen)管(guan)結構的(de)(de)(de)“薄(bo)殼”受力(li)實(shi)踐爲(wei)依據,由(you)于(yu)軸(zhou)向(xiang)(xiang)波(bo)紋(wen)的(de)(de)(de)存在(zai),軸(zhou)向(xiang)(xiang)和徑向(xiang)(xiang)一(yi)起分布因荷載(zai)(zai)惹起的(de)(de)(de)應(ying)力(li)應(ying)變(bian),能夠更(geng)大水平上(shang)渙散荷載(zai)(zai)的(de)(de)(de)應(ying)力(li)集中,充分發揚鋼波(bo)紋(wen)管(guan)結構的(de)(de)(de)劣勢(shi),適應(ying)地基變(bian)形。從材料與結構和功用的(de)(de)(de)實(shi)質關系(xi)上(shang)剖析,選用柔(rou)性高(gao)強度的(de)(de)(de)鋼波(bo)紋(wen)管(guan)涵(han)洞。
不只(zhi)具有適應地(di)基與基礎變形的(de)才干,能夠處理因地(di)基基礎不平均(jun)沉降招致的(de)涵洞破壞成果,并且(qie)鋼(gang)(gang)波紋管(guan)涵洞由于軸向(xiang)波紋的(de)存在使其具有受(shou)力(li)特(te)征(zheng),軸向(xiang)和(he)徑向(xiang)一起分布因荷載(zai)惹起的(de)應力(li)應變,能夠更大水平上(shang)渙散荷載(zai)的(de)應力(li)集中,更好地(di)發(fa)揚鋼(gang)(gang)結構的(de)劣勢。特(te)別在高寒凍土(tu)、軟土(tu)、縮(suo)短(duan)土(tu)、濕陷性黃(huang)土(tu)等(deng)地(di)帶,具有分明(ming)的(de)經濟(ji)效益。
It is not only capable of adapting to the deformation of foundation and foundation, but also can deal with the culvert failure results caused by uneven settlement of foundation. Because of the existence of axial ripple, the steel bellows culvert has the characteristics of stress. The stress stress caused by load is distributed in axial and radial direction, which can concentrate the stress of scattered load at a greater level and develop the disadvantage of steel structure better. Especially in the areas of high cold frozen soil, soft soil, shortening soil and collapsible loess, it has distinct economic benefits.
免除了(le)砼澆筑、鋼筋焊接等工(gong)序,對(dui)周邊噪(zao)聲凈(jing)化較少,并且放棄了(le)慣例(li)建材,如水泥(ni)、砂、石子、木材等,其環保含(han)義深遠。此(ci)工(gong)法操作復雜,現場無(wu)(wu)需大型設備,組裝方法便利可(ke)無(wu)(wu)效延伸施工(gong)周期(qi)。管節(jie)聯接選(xuan)用柔性(xing)對(dui)接卡(ka)箍聯接。
鋼波(bo)紋管避免了(le)傳(chuan)統法(fa)蘭盤剛性聯接的缺點,不只節省了(le)少數聯接螺(luo)栓,并(bing)且裝置裝配、管身調整更爲(wei)簡潔(jie)便利。模(mo)(mo)板(ban)運到施工(gong)現場后,要(yao)(yao)進(jin)行模(mo)(mo)仿(fang)試拼(pin)。試拼(pin)后仔細丈量查看模(mo)(mo)板(ban)加工(gong)精度(du),對精度(du)差的局部(bu)(bu)地方進(jin)行修整,特別要(yao)(yao)注意單元(yuan)塊間(jian)的結合部(bu)(bu)。
如發現精度不能滿足設計要求,退回嚴厲整修。模板裝置要嚴厲按工藝要求進行,預留夠保護層厚度。且接縫均勻留在同一斷面位置上。模板裝置要求裝置同一類其他模板,模板內側涂刷同一類其他脫模劑。選用分片組裝技術,不只能便利涵管的裝卸和運送并且現場施工也易于操控。//hanihanbj.com/
