Assembly type bearing platform anchor cable foundation of power transmission tower and construction method
The invention discloses an assembly type bearing platform anchor cable foundation of a power transmission tower and a construction method. The assembly type bearing platform anchor cable foundation is installed on a binary composite stratum with an upper soil covering layer and a lower bed rock, and the assembly type bearing platform anchor cable foundation comprises a prefabricated bearing platform, a plurality of supporting short columns and pressure type anchor cables. The prefabricated bearing platform is used for installing a tower foot of the power transmission tower, the multiple supporting short columns are supported below the prefabricated bearing platform and fixed to the prefabricated bearing platform; the prefabricated bearing platform and the supporting short columns are buried in the upper soil covering layer; and the pressure type anchor cables sequentially penetrate through the prefabricated bearing platform and the supporting short columns and are anchored into the lower bed rock. According to the assembly type bearing platform anchor cable foundation of the power transmission tower and the construction method, the pressure type anchor cables, the short supporting columns and the prefabricated bearing platform bear iron tower foundation stress under the working conditions of upward pulling, horizontal pressing and downward pressing correspondingly, the advantages of being economical and environmentally friendly are achieved, safe and reliable uplift bearing capacity can be provided, and the burial depth and the section size of the assembly type prefabricated bearing platform can be greatly reduced during design.
本发明公开了一种输电铁塔装配式承台锚索基础及施工方法，安装于具有上部位土覆盖层、下部位基岩的二元复合地层，包括：预制承台，所述预制承台用于安装输电铁塔塔脚；支撑短柱，若干支撑短柱支撑在预制承台下方，并与预制承台固定；其中，所述预制承台和支撑短柱埋设于上部位土覆盖层内；压力型锚索，所述压力型锚索依次穿过预制承台、支撑短柱且锚入下部位基岩内。本发明通过压力型锚索、支撑短柱和预制承台分别承担上拔、水平和下压工况下铁塔基础受力，具有经济环保的优势，有利于提供安全可靠的抗拔承载力，并且设计时可大大减小装配式预制承台的埋深和截面尺寸。
