摘要
针对旋挖桩成孔后塌孔严重的现象,创新采用防塌孔装置,有效解决复杂地质条件下旋挖桩成孔后的塌孔问题,确保了旋挖桩成孔质量,同时避免传统回填方法浪费混凝土,取得良好的经济效益。
In view of the serious collapse of rotary excavation piles after drilling,innovative anti-collapse device is adopted to effectively solve the problem of collapse of rotary excavation piles after drilling under complex geological conditions,ensuring the quality of rotary excavation piles,and avoiding waste of concrete by traditional backfilling methods,thus achieving good economic benefits.
