Northwest region wet-dry freeze-thaw coupling environment fabricated power transmission tower foundation structure
The invention provides a northwest region wet-dry freeze-thaw coupling environment fabricated power transmission tower foundation structure, and belongs to the technical field of energy engineering and structural engineering. A pile cap unit is connected with the upper end of a pile body unit, and the lower end of the pile body unit is connected with a bearing platform. The problems of poor concrete quality, low bearing capacity, low material corrosion resistance, high repair and reinforcement difficulty and the like caused by large-volume integral pouring of concrete in special soil environments such as saline soil, deep soft soil or a large-area weak lower lying layer on the lower portion of a foundation are avoided; construction is efficient and rapid, and the input cost of materials and manpower is saved; in addition, once the foundation is damaged to a certain extent due to the influence of force majeure, damaged parts can be replaced by adopting a direct replacement method, the repair and reinforcement quality and speed are greatly improved, and the foundation construction quality problem, the grounding resistance problem and the repair and reinforcement problem in the service period of the foundation under the field or special geological landform of a power transmission engineering pile foundation to be built at present are effectively solved.
一种西北区湿干冻融耦合环境装配式输电塔基础结构，属于能源工程以及结构工程技术领域。所述桩帽单元与桩身单元的上端连接，所述桩身单元的下端与承台连接。本发明避免了盐渍土、深厚软土或基础下部大面积软弱下卧层等特殊土环境下混凝土大体积整体浇筑所导致的混凝土质量差、承载能力低、材料耐腐蚀性低、修复加固难度高等问题；施工高效快捷，节约材料和人力的投入成本；此外，一旦受不可抗力影响对基础产生一定破坏，可以采用直接置换法对受损部件进行替换即可，大大提高了修复加固质量和速度，有效解决目前待建输电工程桩基础野外或特殊地质地貌下基础施工质量问题，接地电阻问题，以及基础服役期内修复加固问题。
