昆明桥架厂认真学习跨越河道或排洪渠电缆桥架结构专利

       随着城市的发展建设，为美化环境及减少架空输电线路对城市环境的影响，城市内架空输电线路已越来越少，主要采用电缆敷设方式。高压电力电缆跨越河道或排洪渠时，常用的敷设方式有顶管、钢筋混凝土隧道、角钢桁架跨越。顶管施工较为复杂，钢筋混凝土隧道不便于运行检修，角钢桁架整体性与耐腐蚀性能相对较差。
        为了克服上述现有技术中的不足，本实用新型提供了一种跨越河道或排洪渠的、施工简单、方便运行检修、整体性好、耐腐蚀性能好的电缆桥架结构。一种跨越河道或排洪渠的电缆桥架结构，包括采用钢筋混凝土梁式结构设计的横梁侧壁、桥架底板、盖板及用于支撑电缆桥架的灌注桩基础，其中所述盖板开合式盖置于横梁侧壁上方，所述桥架底板固定于横梁侧壁下方，由此形成电缆安置通道，所述灌注桩基础分设于河道或排洪渠两侧。所述电缆安置通道内对称的设置有若干电缆支架，其固定于所述横梁侧壁内壁。电缆支架于固定端相对的一端设置有用于防止电缆滚动的凸沿。横梁侧壁内壁上端设置有用于安装盖板的一级安装台，安装于其上的盖板结合横梁侧壁及桥架底板形成一级电缆安置通道。电缆安置通道下端设置有小型横梁侧壁及小型盖板，所述小型横梁侧壁内壁上端设置有用于安装小型盖板的二级安装台，安装于其上的小型盖板结合小型横梁侧壁及桥架底板形成二级电缆安置通道。灌注桩基础包括基桩与承台，其中所述承台上端开设有嵌置槽，所述横梁侧壁及桥架底板均嵌置于其中。对于跨越河道或排洪渠的电缆桥架，本实用新型采用钢筋混凝土梁式结构设计，使电缆桥架双侧悬挑，结构受力合理，且能与桥梁等周边环境协调，同时电缆桥架的盖板可打开，方便运行检修，施工简单，适用性强且利于推广，从而可以大大提高经济效益与环境效益。
        Kunming bridge factory carefully studies the structure patent of cable bridge across river channel or drainage channel
With the development and construction of the city, in order to beautify the environment and reduce the influence of overhead transmission lines on the urban environment, there are fewer and fewer overhead transmission lines in the city, and cable laying is mainly adopted. When the high-voltage power cable crosses the channel or the drainage channel, the commonly used laying methods include top pipe, reinforced concrete tunnel and Angle steel truss. The top pipe construction is complicated, reinforced concrete tunnel is not easy to operate and overhaul, and the integrity and corrosion resistance of Angle steel truss are relatively poor.
In order to overcome the deficiency of the existing technology, the utility model provides a cross rivers or having drainage, simple construction, convenient operation, maintenance, integral sex is good, good corrosion resistance of cable bridge structure. A cable bridge across river or having canal structure, including the structural design of the reinforced concrete beam, bridge plate, plate and beam wall is used to support cable bridge pile foundation, wherein cover open jewels covered in beam wall above, described bridge plate fixed in the bottom bar side, placed the resulting cable channels, described in the pile foundation set up on or having canal on both sides of the river. A number of cable supports are symmetrically arranged in the cable placement channel and fixed on the inner wall of the lateral wall of the beam. The cable holder is provided with a flange at the opposite end of the fixed end to prevent the cable from rolling. The upper end of the inner wall of the beam side wall is provided with a first-stage installation platform for installing the cover plate. The cover plate installed on it combines the side wall of the beam and the bottom plate of the bridge frame to form a first-stage cable placement channel. Place for cable channel setting of bottom has a small beam wall and small plate, described in the small beam wall wall top set is used to set up small cover plate of the secondary installation units, installed on the small plate combined with small beams on the lateral wall and bridge floor formed secondary cable channel. The cast-in-place pile foundation comprises a foundation pile and a bearing platform, wherein the upper end of the bearing platform is provided with a built-in slot, and the lateral wall of the beam and the bottom plate of the bridge frame are embedded therein. 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 can be opened at the same time, the convenient operation maintenance, simple construction, high applicability and conducive to the promotion, thus can greatly improve the economic benefits and environmental benefits.
