切(qie)開鋼波紋涵管要平(ping)(ping)直，制止(zhi)切(qie)成斜口。卻不再縮(suo)短到本來長度(du)，這(zhe)種變型(xing)收叫做范性(xing)變型(xing)。由彈性(xing)變型(xing)點(dian)(dian)轉變為范性(xing)變型(xing)的時間，叫做屈(qu)撓點(dian)(dian)，其代表(biao)符號是σb，單位是MPa或(huo)N/平(ping)(ping)方毫米。鋼波紋(wen)涵管選用標準化規(gui)劃(hua)，出(chu)產(chan)，規(gui)劃(hua)簡(jian)單，出(chu)產(chan)周期短；工程實際(ji)造(zao)價(jia)比(bi)同類(lei)跨徑的橋，涵洞低。

鋼(gang)波(bo)紋(wen)(wen)涵管(guan)的(de)防(fang)腐處(chu)理(li)需不(bu)低于必定的(de)要求(qiu)，以確保(bao)必定年(nian)限內鋼(gang)波(bo)紋(wen)(wen)涵管(guan)具有(you)(you)足夠的(de)耐侵蝕才能。鋼(gang)波(bo)紋(wen)(wen)涵管(guan)接頭(tou)的(de)方法：鋼(gang)波(bo)紋(wen)(wen)涵管(guan)接頭(tou)處(chu)要外(wai)包0.3米(mi)長(chang)的(de)大號波(bo)紋(wen)(wen)管(guan)，而且兩(liang)端頭(tou)要對半擰緊，中心不(bu)得(de)留有(you)(you)空位。為確保(bao)中心不(bu)留空位，應在(zai)兩(liang)接頭(tou)端頭(tou)處(chu)做(zuo)好符號。

做好后要用膠帶包裹(guo)嚴密，以(yi)防漏漿。抗張強(qiang)度在拉伸(shen)機(ji)的(de)位(wei)力下，試(shi)樣(yang)被位(wei)長(chang)，在著手(shou)時試(shi)樣(yang)的(de)伸(shen)長(chang)和(he)張力成正比，當(dang)張力消除后試(shi)樣(yang)仍(reng)縮短(duan)到本來尺度，試(shi)樣(yang)的(de)這種(zhong)變(bian)型叫做彈(dan)性變(bian)型。考慮(lv)到頂板(ban)鋼(gang)波紋(wen)涵管數量在逐(zhu)漸減少，但凡與鋼(gang)波紋(wen)涵管抵觸的(de)部(bu)件都要躲避(bi)波紋(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.
