mso-hansi-font-family:"Times New Roman"">一、波紋管柔韌性塞規范圍：

mso-hansi-font-family:"Times New Roman"">波紋管柔韌性塞規，用于預應力混凝土橋梁用塑料波紋管柔性試驗，滿足《JT/T529-2016預應力混凝土橋梁用塑料波紋管》標準規范。預應力混凝土橋梁用塑料波紋管產品的分類、技術要求、試驗方法、檢驗規則、標志、包裝、運輸和貯存等。適用于以高密度聚乙烯樹脂(HDPE) mso-hansi-font-family:"Times New Roman"">或聚丙烯(PP) "Times New Roman"">為主要原料，經熱熔擠出成型的預應力混凝土橋梁用塑料波紋管。

mso-hansi-font-family:"Times New Roman"">二、波紋管柔韌性塞規參數：

mso-hansi-font-family:"Times New Roman"">波紋管柔韌性塞規全套7 "Times New Roman"">個，包括Φ50mm "Times New Roman"">、Φ60mm、Φ75mm mso-hansi-font-family:"Times New Roman"">、Φ90mm "Times New Roman"">、Φ100mm "Times New Roman"">、Φ115mm "Times New Roman"">、Φ130mm

mso-hansi-font-family:"Times New Roman"">三、波紋管柔韌性塞規試驗步驟：

1、將一根長1100mm mso-hansi-font-family:"Times New Roman"">的樣件，垂直地固定在測試平臺上，按圖4 mso-hansi-font-family:"Times New Roman"">所示位置安裝兩塊弧形模板，其圓弧半徑r mso-hansi-font-family:"Times New Roman"">應符合表3 "Times New Roman"">規定。

2、在樣件上部900mm mso-hansi-font-family:"Times New Roman"">的范圍內，用手向兩側緩慢彎曲樣件至弧形模板位置( mso-hansi-font-family:"Times New Roman"">見圖4) "Times New Roman"">，左右往復彎曲五次。

3、按圖5 mso-hansi-font-family:"Times New Roman"">所示做一塞規，當樣件彎曲至最終結束位置保持彎曲狀態2min mso-hansi-font-family:"Times New Roman"">后，觀察塞規能否順利地從波紋管中通過。
