摘要
半掏挖斜插基础具有如下特点:基础底部为掏挖部分,砼浇制时可以土代模;立柱和插入角钢的坡度与铁塔腿部主材坡度一致;基础立柱较高而主角钢悬于半空中未达到基础底部,基础顶面为菱形。施工中采用半掏挖斜柱加高全方位高低腿形式的基础,不仅施工工器具简单,操作方便,通用性强,施工优良品率高,经济效益也很明显,其经济性在山区施工中尤其突出。插入角钢的安装与定位都简单易行,与传统的模拟塔腿定位的方法相比劳动强度大大降低,工作效率显著提高。
Half-dig cross-pillar base angel steel lean-inserting foundation has features as follows: the foundation is digging part;the slope of pillar and steel lean-inserting is consistent with that of tower leg;foundation top is diamond.Half-dig cross-pillar base and tower with legs at different height is applied in construction because instruments are simple,effective and economic.Compared with traditional tower leg location,the method is efficiency.
