鋼波紋涵管是(shi)(shi)具有(you)一(yi)定柔性的高強度鋼(gang)管(guan),當(dang)波(bo)型鋼(gang)管(guan)在涵洞中應用后,在動載荷(he)及靜載荷(he)彼此(ci)功效下,管(guan)路從根(gen)底理論上而言就會受(shou)力形(xing)變(bian),鋼(gang)管(guan)將(jiang)側壁上的土壤(rang)(rang)或其他填料(liao)擠(ji)壓到兩邊,但(dan)是(shi)(shi)側壁上壓實的土壤(rang)(rang)對管(guan)道(dao)有(you)反作用力,按(an)捺其變(bian)形(xing)并協助管(guan)道(dao)接受(shou)筆直載荷(he)。

此外(wai),當管道(dao)接(jie)受(shou)荷載時(shi),波(bo)(bo)紋(wen)(wen)鋼涵(han)管管壁周(zhou)圍的應(ying)力分布(bu)均(jun)勻,這(zhe)便(bian)是管土(tu)效(xiao)應(ying)。將試樣在熱或冷的狀況下實施委曲(qu),將鋼波(bo)(bo)紋(wen)(wen)涵(han)管材折彎(wan)90度(du)或120度(du),查緝鋼波(bo)(bo)紋(wen)(wen)涵(han)管材承當委曲(qu)的有經(jing)驗,不一樣鋼波(bo)(bo)紋(wen)(wen)涵(han)管材對委曲(qu)的角度(du)和委曲(qu)的直徑(jing)有不一樣要求。
鋼(gang)波(bo)(bo)紋(wen)涵管接頭的方法:波(bo)(bo)紋(wen)管涵接頭處要外包0.3米(mi)長(chang)的大號波(bo)(bo)紋(wen)管,并且兩(liang)端頭要對半擰緊(jin),中(zhong)心不得留有空位。為保(bao)證中(zhong)心不留空位,應在兩(liang)接頭端頭處做好(hao)符號。做好(hao)后要用(yong)膠帶包裹緊(jin)密(mi),以防漏(lou)漿。切開波(bo)(bo)紋(wen)管涵要平直,禁(jin)止切成斜口。
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.
使用金屬鋼波紋涵管的好處有哪些?
考慮到(dao)頂(ding)板波紋(wen)管(guan)(guan)涵(han)數(shu)量在逐漸削(xue)減,但凡與(yu)波紋(wen)管(guan)(guan)涵(han)抵(di)觸(chu)的(de)部件都要逃避波紋(wen)管(guan)(guan)。抗張強度張力測驗拆模時留(liu)心保護端頭處(chu)外漏(lou)的(de)波紋(wen)管(guan)(guan)涵(han)。耐久性好。依據相關資料,鍍(du)鋅防腐(fu)處(chu)理好的(de)鋼波紋(wen)涵(han)管(guan)(guan)的(de)運用壽命為75年以上,簡直不需要維(wei)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/
