AI Technical Summary
Technical Problem
电塔塔脚安装不稳定是电力行业长期存在的技术难题，主要表现在以下几个方面：基础结构缺陷，传统电塔基础施工多采用水泥灌注桩、直接开挖等方式，需要现场挖泥浆池浇筑水泥，施工完成后需等待28天养护期才能进行后续作业，效率低下，且混凝土基础常因深度和面积不足、浇筑质量差或养护不当导致抗倾覆稳定性不足；地质适应性差，在特殊地质区域，地表沉降会导致塔身受力弯曲和倾斜，严重时引发倒塔断线事故；连接结构不足，角钢塔塔脚焊接变形会影响结构承载能力，模块化连接装置虽能提升适应性，但长期使用后仍存在稳定性下降的问题
Benefits of technology
本实用新型的螺旋锚基础围堰防护装置在安装使用过程中，通过设置的螺旋锚组件和防护组件的相配合使用，可提高整个电塔的稳定性，同时防护组件的结构设计，具体地，通过设置的围挡件和安装板的相互配合，可提高电塔塔脚底部的稳定性，并将塔脚各个支脚的承受力进行分散，不会因为某一处地面发生沉降而影响电塔的正常使用。
