中文摘要 | TL-96人孔蓋係為改善TL-90人孔蓋不易開啟,且使蓋板能單獨適用於目前既設之 舊有人孔蓋蓋座,並具防跳脫功能而設計之人孔鑄鐵蓋。其特點為能適用於一般道路,具防 跳脫功能,較易開啟;而且在交通繁忙道路,只要更換損壞或跳動之既設舊有人孔蓋之蓋板 時, 不用更換蓋座也能使用其蓋板且具防跳脫功能。 本文利用有限元素分析法, 以 MSC/NASTRAN 軟體進行結構分析,求得人孔蓋於車輛荷重下之應力及位移。並依據結構分析 之結果及人孔蓋之實際需要條件設計。經由實體製件,進行靜載重抗壓強度試驗及防跳脫試 驗後, 再由北、中、南區分公司進行四個月的現場試用追蹤測試,結果顯示 TL-96 人孔蓋 的安全性、施工性、平穩性、啟閉性及與舊蓋座(或升高套環)之相容性均有很好的表現。 |
英文摘要 | The TL-96 Manhole Cover with rabbet device is designed for improving the inconvenience of lifting the lid of TL-90 Manhole Cover, and fitting the base frame of the existing traditional manhole covers. The TL-96 Manhole Cover is jumping-resistant, convenient to open and can just replace the lid of the existing traditional manhole covers without changing its base frame. By using the structure analysis package, "MSC/NASTRAN" designed by finite element method, the stresses and displacements of the manhole cover under the designed vehicle load were calculated. According to the results of the structure analysis and the functional requirements, the TL-96 Manhole Cover was designed and the prototypes were manufactured. Through the static loading test, jumping-resistant test, and field trial in Northern, Central and Southern Taiwan Business Group of Chunghwa Telecom, the TL-96 Manhole Cover represents very good performance in safety, stability, workability and lift, and is compatible with the existing traditional manhole covers (or extension rings). |
