中文摘要 | 一般因新社區產生,提出通信用纜線之需求時,建設單位往往須在既有路由之兩舊 手孔間新設一手孔,以引出或擴充新管線提供用戶之需,因此剖開既有管道新設手孔之技術 必須建立,有鑑於此,本文提出一新型之預鑄剖管型手孔,主要將手孔塊體全部旖工廠預鑄 化,再到現場安裝施工。本產品組成分下部及上部結構,下部結構分割成三塊來組裝,在複 雜之地下空間下可增加施工作業靈活度,上部結構包括一無鋼筋混凝土之薄側壁,鑿除後可 容許多數管道銜接進入手孔。本新型手孔因塊體全部預鑄化,故其強度將比現場澆灌鑄造者 更有保證。 本產品完成設計後,製造出實體成品,並經實驗室靜載重測試後,實際於現場多處地點 安裝試用,經評估結果,除泄品強度好外,並具有安裝迅速容易之優點,故建議能將本產品 納入現有預鑄水泥混凝土手孔之規格內。 |
英文摘要 | When the demand for telecommunication cable for new community occurs. We usually need to construct a new handhole between two existing handholds. Thus, it is necessary to cut off existing pipe for installing new handhole which to draw forth or expand cable. This paper submits a new type precast cut-conduit handhole to solve this issue, It divides into three precast parts at lower layer and a upper part within thin steelless side wall where multi-pipe can enter into handhole. The workability is flexible at complicated underground space. Furthermore, this product is manufactured by means of all precast concrete by factory. That can ensure more stronger than the field mold product. This product has been designed and manufactured. After completing static loading test, we make field try at the different sites. We prove its application feasibility that can be quickly installed and have high quality. It is recommended that the current specification of precast hnadhole can include this specific product. |
