切開鋼波紋涵管要(yao)平(ping)(ping)直，制止切(qie)成斜口(kou)。卻不(bu)再縮短到本(ben)來(lai)長度(du)，這(zhe)種變(bian)型(xing)收叫做范(fan)性(xing)變(bian)型(xing)。由彈性(xing)變(bian)型(xing)點轉變(bian)為(wei)范(fan)性(xing)變(bian)型(xing)的時間，叫做屈撓(nao)點，其(qi)代表符(fu)號(hao)是(shi)σb，單位(wei)是(shi)MPa或N/平(ping)(ping)方毫(hao)米。鋼波紋(wen)涵(han)管選用(yong)標準(zhun)化規(gui)劃，出(chu)產，規(gui)劃簡單，出(chu)產周期短；工(gong)程(cheng)實際造價比同(tong)類跨(kua)徑的橋(qiao)，涵(han)洞低。

鋼(gang)(gang)波(bo)(bo)紋涵管(guan)(guan)的防腐(fu)處理(li)需不低于(yu)必定的要求，以確保(bao)必定年限內鋼(gang)(gang)波(bo)(bo)紋涵管(guan)(guan)具有足夠的耐(nai)侵蝕才能。鋼(gang)(gang)波(bo)(bo)紋涵管(guan)(guan)接(jie)頭(tou)的方(fang)法：鋼(gang)(gang)波(bo)(bo)紋涵管(guan)(guan)接(jie)頭(tou)處要外包0.3米(mi)長的大號(hao)波(bo)(bo)紋管(guan)(guan)，而且兩端(duan)頭(tou)要對半擰緊，中(zhong)心不得留(liu)有空位(wei)。為確保(bao)中(zhong)心不留(liu)空位(wei)，應在兩接(jie)頭(tou)端(duan)頭(tou)處做好符號(hao)。

做好后(hou)要(yao)用(yong)膠帶包裹嚴密，以防漏漿。抗張強度在拉(la)伸(shen)(shen)機的位(wei)力下，試(shi)樣被位(wei)長，在著手時試(shi)樣的伸(shen)(shen)長和張力成(cheng)正比(bi)，當(dang)張力消(xiao)除后(hou)試(shi)樣仍縮短到本來尺度，試(shi)樣的這種變型叫做彈(dan)性變型。考慮到頂(ding)板鋼波(bo)紋(wen)涵管數量(liang)在逐漸減少，但凡與(yu)鋼波(bo)紋(wen)涵管抵觸的部(bu)件(jian)都要(yao)躲(duo)避波(bo)紋(wen)管。

After completion, it shall be tightly wrapped with adhesive tape to prevent slurry leakage. Tensile strength under the potential force of the tensile machine, the sample is lengthened. When starting, the elongation of the sample is directly proportional to the tension. When the tension is eliminated, the sample is still shortened to the original scale. This deformation of the sample is called elastic deformation. Considering that the number of steel corrugated culvert pipes on the top plate is gradually decreasing, all parts that conflict with steel corrugated culvert pipes should avoid corrugated pipes.

施工(gong)工(gong)期(qi)短，主要為拼裝施工(gong)；金屬(shu)鋼(gang)波(bo)紋涵管替代鋼(gang)筋混凝土進(jin)(jin)行(xing)涵洞施工(gong)，不(bu)管從(cong)施工(gong)周(zhou)期(qi)，施工(gong)造價(jia)，環保含義等(deng)方面都有其(qi)不(bu)可比擬的(de)(de)優越性。鋼(gang)波(bo)紋涵管有利于改(gai)進(jin)(jin)軟土，脹大土，濕(shi)陷性黃(huang)土等(deng)特別地基結構物(wu)處的(de)(de)不(bu)均勻沉降問題。

提高了公路服務功能，減少了工后維護本錢；減少了水泥，塊片石或碎石，砂等的用量，有利于環保；南邊區域地下水多帶有不同程度的腐蝕性，一起山嶺重丘區域地表水流湍急，季節性降雨沖刷嚴峻。//hanihanbj.com/
