新型的大跨距電纜橋架具體實施方式

新型的電纜橋架具體實施方式

本實用新型提供了一種跨越河道或排洪渠的、施工簡單、方便運行檢修、整體性好、耐腐蝕性能好的電纜橋架結構。該電纜橋架結構主要包括采用鋼筋混凝土梁式結構設計的橫梁側壁1、橋架底板2、蓋板及用于支撐電纜橋架的灌注樁基礎，其中蓋板 3 開合式蓋置于橫梁側壁 1 上方，橋架底板 2 固定于橫梁側壁 下方，由此形成一個貫通式的電纜安置通道，灌注樁基礎分設于河道或排洪渠兩側，電纜橋架兩側懸挑于其上。在上述的電纜安置通道中，橫梁側壁 1 內壁上對稱的設置有若干電纜支架 6，電纜支架 6 可用于置電纜，同時其固定端相對的一端還設置有可防止電纜滾動的凸沿。關于蓋板 3 與橫梁側壁 1 的安裝，上述的橫梁側壁 1 內壁的上端設置有呈梯級狀的一級安裝臺，蓋板 3 可開合式的安裝于其上，結合橫梁側壁 1 及橋架底板 2 便形成一級電纜安置通道。同時，一級電纜安置通道的下端設置有小型橫梁側壁 11 及小型蓋板 31，小型橫梁側壁 11的內壁上端同樣設置有呈梯級狀的二級安裝臺，安裝于其上的小型蓋板 31 結合小型橫梁側壁 11 及橋架底板 2 即形成二級電纜安置通道。此外，灌注樁基礎包括基樁 4 與承臺 5，其中承臺 5 上端開設有嵌置槽，橫梁側壁 1及橋架底板 2 均可嵌置于其中。對于跨越河道或排洪渠的電纜橋架，本實用新型采用鋼筋混凝土梁式結構設計， 使電纜橋架雙側懸挑，結構受力合理，且能與橋梁等周邊環(huán)境協(xié)調，同時電纜橋架的蓋板 3、小型蓋板 31 可打開，方便運行檢修，施工簡單，適用性強且利于推廣，從而可以大大提高經濟效益與環(huán)境效益。以上所述，只是本實用新型的較佳實施方式而已，但本實用新型并不限于上述實施方式，只要其以任何相同或相似手段達到本實用新型的技術效果，都應落入本實用新型的保護范圍之內。

The utility model provides a cable bridge structure with simple construction, convenient operation and maintenance, good integrity and good corrosion resistance. The cable bridge structure mainly includes the structure design of reinforced concrete beam using beam wall 1, bridge floor 2, cover plate, and used to support the cable bridge pile foundation, which cover three jewels covered in beam wall above 1, bridge floor 2 fixed in the bottom of beam wall, thus forming a through type cable channel, pile foundation set up on or having canal on both sides of the river channel, cable bridge on both sides of the cantilever on it. Placed in the cable channel, wall beam wall 1 symmetrical, several cable bracket set 6, 6 can be used to buy cable bracket, at the same time its relatively fixed end can prevent the cable is also set in one side of the protruding along the roll. On cover plate and beam side 1 3 installation, the beam wall 1 set with the top of the wall with a cascade of level 1 installation, cover 3 can open the installation of the jewels on it, combining beam wall and bridge floor 2 it forms first-stage cable channel. At the same time, the level of the lower end of the place for cable channel set has a small beam wall 11 and small plate 31, 11 the lining of the small beam side top also set a cascade of secondary installation units, installed on the small plate combined with 31 small beam wall is formed namely 11 and bridge floor 2 secondary cable channel. In addition, the cast-in-place pile foundation includes foundation pile 4 and bearing platform 5, in which the upper end of bearing platform 5 is provided with an embedded slot, in which both the lateral wall of the beam 1 and the bottom plate of the bridge frame 2 can be embedded. For cable bridge across the river or having canal, the utility model adopts the design of reinforced concrete beam structure, make the cable tray bilateral cantilever, reasonable structure, and can be coordinated with surrounding environment, such as Bridges, cable tray cover 3 at the same time, small 31 can open the cover, convenient maintenance operation, simple construction, high applicability and conducive to the promotion, thus can greatly improve the economic benefits and environmental benefits. Described above, is a better implementation method of the utility model, but the utility model is not limited to the above implementation way, as long as its the same or similar to any means to reach the technical effect of the utility model, both shall fall into the utility model protection scope.
