鋼波紋涵管為何采用現在這樣的構造處理?

管壁及配套附件均經由熱浸鍍(du)鋅處(chu)理,其鍍(du)鋅層(ceng)的(de)均勻厚度大于84um.涵(han)管運至(zhi)施工現(xian)場后(hou),工地(di)現(xian)場涂刷兩邊(bian)瀝青。

構造處(chu)(chu)(chu)理:波(bo)紋為(wei)圓形整(zheng)體管(guan),采用(yong)(yong)(yong)(yong)整(zheng)管(guan)節拼裝(zhuang)、法蘭(lan)螺(luo)栓連接。金屬(shu)波(bo)紋涵管(guan)加工后須采用(yong)(yong)(yong)(yong)熱(re)(re)鍍鋅等防腐處(chu)(chu)(chu)理。采用(yong)(yong)(yong)(yong)鍍鋅鋼(gang)板加工的,在加工后必需進行二次處(chu)(chu)(chu)理。整(zheng)體管(guan)連接法蘭(lan)采用(yong)(yong)(yong)(yong)角(jiao)鋼(gang)、鋼(gang)板制(zhi)作,波(bo)紋板焊(han)接采用(yong)(yong)(yong)(yong)對焊(han)接頭。緊(jin)(jin)(jin)固件采用(yong)(yong)(yong)(yong)國(guo)標(biao)中的尺度(du)緊(jin)(jin)(jin)固件,其強度(du)和規格應知足力學要求,且不低于管(guan)材強度(du)要求。墊(dian)片(pian)與緊(jin)(jin)(jin)固件相配。螺(luo)栓與螺(luo)母均采用(yong)(yong)(yong)(yong)熱(re)(re)浸鍍鋅處(chu)(chu)(chu)理。

金屬波(bo)(bo)紋涵(han)管的防水(shui)及(ji)排(pai)水(shui)施工中為(wei)(wei)防止波(bo)(bo)紋涵(han)管外發生(sheng)的水(shui)壓(ya),有必要(yao)設置(zhi)排(pai)水(shui)設備盡量(liang)降低水(shui)壓(ya)(按捺發生(sheng)水(shui)壓(ya)會(hui)加重波(bo)(bo)紋涵(han)管填土(tu)部位的載(zai)荷,會(hui)影響(xiang)波(bo)(bo)紋涵(han)管的變(bian)位)為(wei)(wei)了(le)防止從鋼(gang)板連接部及(ji)螺(luo)栓孔滲水(shui),在(zai)螺(luo)栓連接部和鋼(gang)板重疊部選擇密(mi)封材(cai)料進行(xing)表(biao)面防水(shui)處理(li)地下通道在(zai)組裝完畢后,回(hui)填之(zhi)前(qian)實(shi)施表(biao)面防水(shui)防水(shui)處理(li)后待防水(shui)材(cai)料充分硬化(hua)后開始回(hui)填、回(hui)填及(ji)壓(ya)實(shi)(1)波(bo)(bo)形(xing)鋼(gang)板構(gou)(gou)造物的回(hui)填與(yu)壓(ya)實(shi)對構(gou)(gou)造物的不(bu)亂性及(ji)耐久性起著重要(yao)的作用。波(bo)(bo)形(xing)鋼(gang)板是(shi)一種彈性結構(gou)(gou),所以(yi)填土(tu)特別重要(yao)。

金屬波(bo)(bo)紋(wen)(wen)涵管(guan)(guan)按地(di)中構(gou)造物(wu)使用時,土體和波(bo)(bo)形鋼(gang)板有(you)合成作用能承(cheng)受外部(bu)載(zai)(zai)荷(he),因此金屬波(bo)(bo)紋(wen)(wen)涵管(guan)(guan)及(ji)(ji)土體共同承(cheng)受載(zai)(zai)荷(he)的(de)作用。金屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵也叫(jiao)波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵或鋼(gang)制波(bo)(bo)紋(wen)(wen)涵管(guan)(guan),是(shi)指鋪埋在公路,鐵路下(xia)面(mian)的(de)涵洞用螺(luo)紋(wen)(wen)波(bo)(bo)紋(wen)(wen)管(guan)(guan),它是(shi)由波(bo)(bo)形金屬板卷(juan)制成或用半圓(yuan)波(bo)(bo)形鋼(gang)片拼制成的(de)圓(yuan)形波(bo)(bo)紋(wen)(wen)管(guan)(guan),應用于公路,鐵路,小橋(qiao),通道,擋土墻以(yi)及(ji)(ji)各種礦場,巷(xiang)道擋墻支護等工程中的(de)涵洞(管(guan)(guan))

金屬波(bo)(bo)紋涵(han)管(guan)(guan)具有施工工期短、造價(jia)低、對(dui)地(di)(di)基擾動小、對(dui)基礎要求低、適(shi)應(ying)變(bian)形機能(neng)好(hao)等長處,特別(bie)合用于邊(bian)遠地(di)(di)區(qu)和多年凍土、軟土等特殊地(di)(di)基區(qu)域(yu)的(de)道(dao)路涵(han)洞(dong)工程.目前,作(zuo)為一種新型(xing)的(de)道(dao)路涵(han)洞(dong)形式.對(dui)鋼(gang)(gang)波(bo)(bo)紋管(guan)(guan)涵(han)洞(dong)進(jin)行野(ye)(ye)外(wai)(wai)現(xian)場(chang)力學機能(neng)測(ce)試(shi)存(cun)在很多局限(xian)(xian)性(xing),為了(le)克服其局限(xian)(xian)性(xing),本(ben)文在鋼(gang)(gang)波(bo)(bo)紋管(guan)(guan)涵(han)洞(dong)野(ye)(ye)外(wai)(wai)現(xian)場(chang)力學機能(neng)測(ce)試(shi)的(de)基礎上(shang),利用有限(xian)(xian)元力學分(fen)(fen)析(xi)程序對(dui)鋼(gang)(gang)波(bo)(bo)紋管(guan)(guan)涵(han)洞(dong)的(de)受力變(bian)形作(zuo)計(ji)算分(fen)(fen)析(xi),將計(ji)算結果(guo)和野(ye)(ye)外(wai)(wai)現(xian)場(chang)實測(ce)值進(jin)行比較分(fen)(fen)析(xi),建立公道(dao)的(de)有限(xian)(xian)元力學模型(xing),運用有限(xian)(xian)元法系(xi)統地(di)(di)分(fen)(fen)析(xi)鋼(gang)(gang)波(bo)(bo)紋管(guan)(guan)涵(han)洞(dong)的(de)力學機能(neng)成為可(ke)行. 

鋼波紋涵管

鋼波紋涵管設計步驟結構分析:本圖假定波紋管和(he)土(tu)體均為彈性體。不(bu)考慮涵洞頂土(tu)柱和(he)附(fu)近填土(tu)間的摩(mo)擦力(li),采用角度分布(bu)法(fa)計算,半無(wu)窮彈性體理(li)論(lun)核算。土(tu)重:按土(tu)柱重理(li)論(lun)計算,內摩(mo)擦角φ=30°,土(tu)容量18KN/ m3.
