Construction method for high-low leg foundation of power transmission tower in mountainous area
The invention discloses a construction method of a high-low leg foundation of a power transmission tower in a mountainous area, solves the problem that concrete splashed to a template influences the quality of a tower footing in the prior art, and has the beneficial effect of ensuring the quality of the part, exposed out of the ground, of the tower footing. Comprising the steps that a construction datum plane is determined, the horizontal plane of the top end of the tower footing burial depth at the high slope position serves as the construction datum plane, and the construction datum plane is higher than the top of a center pile; according to the positions of the pile foundations, drilling is started on the mountain slope to form pile foundation drill holes; an isolation piece is movably fixed to the inner surface of the formwork for concrete pouring, and the isolation piece can move relative to the formwork for concrete pouring under the action of external force; a formwork for concrete pouring is arranged on the peripheral side of the top of the pile foundation drill hole, and the clamp is fixed to the annular direction of the formwork for concrete pouring; and concrete is injected into the pile foundation drill hole, and the isolation piece is lifted upwards till the concrete is poured to the designed elevation.
本发明公开了一种山区输电铁塔高低腿基础的施工方法，解决了现有技术中飞溅到模板处的混凝土影响塔基质量的问题，具有保证塔基外露于地面部分的质量的有益效果，具体方案如下：一种山区输电铁塔高低腿基础的施工方法，包括确定施工基准面，以斜坡较高位置处塔基埋深的顶端所在水平面作为施工基准面，该施工基准面高于中心桩的顶部设置；根据各桩基的位置在山区斜坡开始钻孔形成桩基钻孔；在混凝土浇筑用模板的内表面活动固定隔离件，在外力作用下，隔离件相对于混凝土浇筑用模板可移动；在桩基钻孔顶部周侧设置混凝土浇筑用模板，夹具固定于混凝土浇筑用模板的环向；对桩基钻孔注入混凝土，向上提升隔离件，直至混凝土浇筑至设计标高。
