输电线路铁塔基础施工后弃土处置方法

Discarded Soil Disposal Method After Transmission Line Tower Foundation Construction

分析了铁塔基础施工过程中弃土的产生、弃土处置现状、弃土处置不当造成的影响,综合考虑塔位处地形实际情况,总结了弃土处置的几种措施,主要包括调整基础主柱外露高度,将弃土堆放在塔基范围内;在远离塔位寻找安全稳定位置修筑堡坎,将弃土堆放在堡坎内;塔基堆放结合修筑堡坎;在塔位附近的洼地、凹坑中堆放弃土以及弃土综合利用。为了尽量减小弃土产生的各种不利影响,建议在工程设计阶段,应做好基础选型优化,从源头上减少弃土土方量;在终勘定位过程中,相关专业应加强协同配合,合理确定弃土的处置措施;在施工阶段,当需修筑堡坎时,应严格按施工要求进行施工。

Make a detailed analysis to the generation of discarded soil,the present situation of discarded soil disposal,the impact of the inappropriate disposal to discarded soil,comprehensive considering the actual situation of tower located at the landform,it summarizes several measures of discarded soil disposal.These measures include to adjust the exposed height of foundation column,put the discarded soil in the range of the tower foundation;to build retaining wall in the safe and stable position away from the tower foundation and put the discarded soil in the range of the retaining wall;to build retaining wall and put the discarded soil between the range of the tower foundation and retaining wall;to put the discarded soil in the low-lying land or crater and make use of discarded soil comprehensively.In order to minimize the adverse effects of discarded soil,in the engineering design stage,it should be selected suitable foundation design to optimize,reduce the amount of discarded soil from the source.In the process of final survey,relevant professional should strengthen cooperation,determine the disposal measures of discarded soil rationally.In the construction stage,if building retaining wall to dispose discarded soil,it should obey the construction requirements.
