绝壁悬挑钻探施工平台研制

Research and Development of the Cantilever Drilling Construction Platform on Beetling Wall

本文以长江巫峡黄岩窝和板壁岩特大型危岩带勘查水平孔施工为例,探索研究出在无地面支撑基础条件、近似直立的岩石绝壁上建设钻探施工平台的施工方案。采用斜撑和锚拉结构受力体系,通过力学分析和计算,形成了一套较完整的施工工艺,对解决类似的工程施工平台难题具有一定的指导和参考价值。

Taking an exploration horizontal hole construction as the example,which was in the oversize dangerous rocks zone in Huangyanwo and Banbiyan of Yangtze River Wuxia,the construction scheme of drilling platform was explored,the construction was carried out under the conditions of approximate vertical rock beetling wall without ground foundation.With the stress system of diagonal braces and anchorage structures,a complete set of construction technology is developed by the mechanical analysis and calculation,which has certain guidance and reference value for solving difficulties of similar engineering construction platform.
