中空壁塑鋼纏繞(rao)管用新型涉及一種管道,尤(you)其是中空(kong)壁(bi)塑鋼纏繞管(guan)。其由若(ruo)干(gan)個環(huan)(huan)形(xing)(xing)(xing)(xing)(xing)高(gao)(gao)密(mi)度(du)(du)(du)(du)聚(ju)乙(yi)烯(xi)(xi)(xi)塑(su)鋼板(ban)帶通過線(xian)型低(di)密(mi)度(du)(du)(du)(du)聚(ju)乙(yi)烯(xi)(xi)(xi)底膠拼接(jie)而成(cheng),高(gao)(gao)密(mi)度(du)(du)(du)(du)聚(ju)乙(yi)烯(xi)(xi)(xi)塑(su)鋼板(ban)帶主要由外(wai)壁(bi)和內(nei)壁(bi)組成(cheng),外(wai)壁(bi)與(yu)內(nei)壁(bi)之間(jian)形(xing)(xing)(xing)(xing)(xing)成(cheng)有環(huan)(huan)形(xing)(xing)(xing)(xing)(xing)加強(qiang)筋(jin),加強(qiang)筋(jin)將外(wai)壁(bi)與(yu)內(nei)壁(bi)之間(jian)所夾(jia)區域分隔(ge)成(cheng)若(ruo)干(gan)個封閉的(de)環(huan)(huan)形(xing)(xing)(xing)(xing)(xing)空腔,高(gao)(gao)密(mi)度(du)(du)(du)(du)聚(ju)乙(yi)烯(xi)(xi)(xi)塑(su)鋼板(ban)帶的(de)前后拼接(jie)面(mian)均為環(huan)(huan)形(xing)(xing)(xing)(xing)(xing),線(xian)型低(di)密(mi)度(du)(du)(du)(du)聚(ju)乙(yi)烯(xi)(xi)(xi)底膠填充于相鄰高(gao)(gao)密(mi)度(du)(du)(du)(du)聚(ju)乙(yi)烯(xi)(xi)(xi)塑(su)鋼板(ban)帶的(de)環(huan)(huan)形(xing)(xing)(xing)(xing)(xing)拼接(jie)面(mian)之間(jian)。加強(qiang)筋(jin)中設有環(huan)(huan)形(xing)(xing)(xing)(xing)(xing)鋼帶,鋼帶的(de)軸線(xian)與(yu)環(huan)(huan)形(xing)(xing)(xing)(xing)(xing)高(gao)(gao)密(mi)度(du)(du)(du)(du)聚(ju)乙(yi)烯(xi)(xi)(xi)塑(su)鋼板(ban)帶的(de)軸線(xian)相重合。它(ta)制(zhi)作簡單(dan)成(cheng)本(ben)低(di),板(ban)帶纏繞制(zhi)管(guan)工序簡化,易(yi)操控(kong),成(cheng)品率(lv)高(gao)(gao)；鋼帶與(yu)板(ban)帶垂直(zhi)分布,環(huan)(huan)剛度(du)(du)(du)(du)大(da)大(da)提高(gao)(gao),且受(shou)力分布均衡故制(zhi)品承載(zai)能力強(qiang)、穩定持久。
