鋼波紋涵管是具有一定柔性(xing)的(de)高強度鋼(gang)管(guan)(guan)(guan),當波型鋼(gang)管(guan)(guan)(guan)在涵洞(dong)中應用后(hou),在動載荷(he)及靜載荷(he)彼此(ci)功效下,管(guan)(guan)(guan)路從根底(di)理論上而言就會受力形變,鋼(gang)管(guan)(guan)(guan)將側壁上的(de)土壤(rang)或其(qi)他填料擠壓(ya)到兩邊(bian),但(dan)是側壁上壓(ya)實的(de)土壤(rang)對管(guan)(guan)(guan)道有反作用力,按捺其(qi)變形并(bing)協(xie)助管(guan)(guan)(guan)道接受筆直載荷(he)。

此外(wai),當管道接受(shou)荷(he)載(zai)時,波紋(wen)(wen)(wen)鋼涵管管壁周圍的(de)(de)應(ying)力分(fen)布均勻,這便是管土效應(ying)。將(jiang)試樣(yang)在熱或冷的(de)(de)狀況下(xia)實施委(wei)曲(qu),將(jiang)鋼波紋(wen)(wen)(wen)涵管材(cai)折彎90度(du)或120度(du),查緝鋼波紋(wen)(wen)(wen)涵管材(cai)承當委(wei)曲(qu)的(de)(de)有經驗,不(bu)一樣(yang)鋼波紋(wen)(wen)(wen)涵管材(cai)對委(wei)曲(qu)的(de)(de)角度(du)和(he)委(wei)曲(qu)的(de)(de)直徑有不(bu)一樣(yang)要求。
鋼波(bo)(bo)紋涵管(guan)(guan)接頭(tou)的方(fang)法:波(bo)(bo)紋管(guan)(guan)涵接頭(tou)處要(yao)外(wai)包0.3米長的大(da)號(hao)波(bo)(bo)紋管(guan)(guan),并且兩端(duan)頭(tou)要(yao)對半擰緊,中心不(bu)得(de)留(liu)有空(kong)位(wei)。為保證中心不(bu)留(liu)空(kong)位(wei),應在(zai)兩接頭(tou)端(duan)頭(tou)處做好符號(hao)。做好后(hou)要(yao)用膠帶包裹緊密,以防(fang)漏漿。切開(kai)波(bo)(bo)紋管(guan)(guan)涵要(yao)平直,禁止(zhi)切成斜口(kou)。
Method of steel corrugated culvert joint: 0.3m long large corrugated pipe shall be wrapped at the corrugated culvert joint, and both ends shall be tightened in half, and there shall be no space in the center. In order to ensure that there is no vacancy in the center, symbols shall be made at the ends of the two joints. After completion, it shall be wrapped tightly with adhesive tape to prevent slurry leakage. The cut corrugated pipe culvert shall be straight and straight, and oblique cutting is prohibited.

考慮到頂板波(bo)紋(wen)管(guan)涵(han)(han)(han)數量在逐(zhu)漸削減(jian),但凡與波(bo)紋(wen)管(guan)涵(han)(han)(han)抵(di)觸(chu)的部件都要逃避波(bo)紋(wen)管(guan)。抗張強度張力測驗拆模時留心保護端頭(tou)處外漏的波(bo)紋(wen)管(guan)涵(han)(han)(han)。耐(nai)久性好。依(yi)據相關資料,鍍鋅(xin)防腐處理好的鋼波(bo)紋(wen)涵(han)(han)(han)管(guan)的運用壽(shou)命為75年以上,簡直不需(xu)要維護。
對涵洞來說,這樣的運用壽命完全能夠滿意相關標準的要求。對于地溝敷設的熱力管網,當補償器所在管道地形較低時,雨水或事故性污水會浸泡波紋管,應考慮選用耐腐蝕性更強的資料,如鐵鎳合金、高鎳合金等。//hanihanbj.com/
