Bar-shaped power transmission and transformation overhead line iron tower foundation structure and construction method thereof
The invention relates to a strip-shaped power transmission and transformation overhead line iron tower foundation structure and a construction method thereof, and the structure comprises a strip-shaped foundation part which is buried in a foundation pit of an undisturbed soil layer and comprises a plurality of strip-shaped structures which are arranged in a crisscross manner; the plurality of column foot connecting parts are used for connecting tower legs of the iron tower; each column foot connecting part comprises a plurality of foundation bolts which are at least partially embedded in the strip-shaped foundation part; the backfill soil layer is arranged above the strip-shaped foundation part and the undisturbed soil layer in a compacted mode, and the column foot connecting part is exposed out of the backfill soil layer. According to the foundation structure, the problems that in a power transmission and transformation project, common foundation forms such as a cast-in-place pile foundation, a rock anchor rod foundation and an excavation foundation are prone to generating differential settlement in areas with complex geological conditions, and large disturbance is generated to underground water due to the fact that the excavation depth is too large in areas with the shallow underground water level are solved. While the structural safety is ensured, the construction process is simplified, the construction cost is reduced, and a more efficient solution is provided for power grid construction.
本发明为一种条形输变电架空线路铁塔基础结构及其施工方法，该结构包括：埋设于原状土层的基坑内的条形基础部，包括多条呈纵横相交设置的条形结构；多个柱脚连接部，用于连接铁塔塔腿；各柱脚连接部包括多个至少部分埋设于条形基础部内的地脚螺栓；回填土层，压实设置于条形基础部及原状土层的上方，柱脚连接部外露于回填土层。本发明解决输变电工程中常见的灌注桩基础、岩石锚杆基础、掏挖基础等基础形式在地质条件复杂地区易产生不均匀沉降、在地下水位较浅地区开挖深度过大对地下水产生较大扰动等问题，本发明采用条形基础结构支撑连接铁塔塔腿，在保证结构安全性的同时，简化施工工艺，降低工程造价，为电网建设提供更加高效的解决方案。
