Construction method for foundation of electric power iron tower of power transmission line

WANG JIE

The invention provides a construction method for a foundation of an electric power iron tower of a power transmission line. The construction method comprises a joint control mechanism, a main body mechanism and a platform straight plate, wherein the platform straight plate is arranged on the main body mechanism in a sliding fit mode, and the joint control mechanism is installed on the end surface of the middle of the platform straight plate. According to the construction method, the problems that in the existing foundation pouring construction process, a fixing mode of foundation bolts is usually clamping and fixing by adopting a single piece of channel steel or a batten, the foundation bolts cannot be effectively fixed in the mode, so that the perpendicularity of the foundation bolts exceeds an error allowable range, the exposure height of the foundation bolts is difficult to synchronously control, the moving distance between the centers of the foundation bolts and the center of the foundation is difficult to synchronously control, long-time adjustment and fixing are needed, so that the construction efficiency of the foundation is low, the construction quality of the iron tower foundation is difficult to guarantee, and the stability of the foundation bolts applied to a connecting foundation and the power transmission line iron tower is influenced are solved.

本发明提供了一种输电线路电力铁塔基础建造施工方法，包括联控机构、主体机构和平台直板，所述的主体机构上通过滑动配合方式设置有平台直板，位于平台直板的中部端面上安装有联控机构；本发明解决了现今在基础浇筑施工过程中，对于地脚螺栓的固定方式通常是采用单块槽钢或木条夹紧固定，此方式不能有效的固定地脚螺栓，造成地脚螺栓的垂直度超出误差允许范围，并且针对地脚螺栓的露出高度难以同步控制，地脚螺栓中心和基础中心移动间距难以同步控制，需要长时间的调节固定，造成基础建造施工效率低下，难以保证铁塔基础建造施工的质量，会影响地脚螺栓应用在连接基础和输电线路铁塔中的稳定性等问题。
