长螺旋钻孔压灌桩工艺在田庄选煤厂快速装车站基础施工中的应用

Application of long helical drilling pressure filling pile process in technical renovation at Tianzhuang coal preparation plant

针对快速装车站建设场地存在的施工难题,田庄选煤厂采用长螺旋钻孔压灌桩工艺对快装站基础进行施工。文章详细阐述了该工艺施工方法和控制要点,并介绍了其在田庄选煤厂快速装车站基础施工中的应用效果,实践表明:长螺旋钻孔压灌桩工艺大大缩短了施工工期,节约了施工费用,在老厂改造的基础施工中具有良好的推广应用前景。

According to the difficulties encountered in constructing of speed loading station, Tianzhuang coal preparation plant decided using the long helical drilling pressure filling pile process in constructing of the foundation, the paper detailed described the operation method and control points of the construction process. The construction practice shows that using the long helical drilling pressure filling pile process can remarkably shorten the construction period, saved the construction cost, so it has the good prospect of popularizing and application in the foundation construction in the reformation of the old plant.
