AI Technical Summary
Technical Problem
During the backfilling process of the dam, some areas suffered severe subsidence when the compactor was used to compact the earth, which required refilling and affected efficiency.
Method used
Design a device for backfilling and embankment construction of dam earthwork, including a limiting slide, a compaction mechanism and a filling mechanism. Through the cooperation of the compaction block of the compaction mechanism and the filling mechanism, automatic filling and compaction of the depressed area can be achieved.
Benefits of technology
This improved the efficiency of dam backfilling, ensuring that sunken areas could be filled and flattened in a timely manner, avoiding splashing of fill material, and improving construction efficiency.

Abstract
本发明涉及水利施工技术领域。本发明公开了一种大坝土方回填筑埂装置及方法，本发明要解决的问题是夯实机对坝体进行压平时，部分区域凹陷较为严重，这时就需要再次对凹陷的区域进行填料，影响效率。本发明由夯实机构、填料机构和往复压实机构组成。该大坝土方回填筑埂装置及方法通过推动偏转卡杆偏转带动圆柱块在限位槽内滑动，使得料箱内的填料流入到集料箱内，然后在夯实块上移复位完成时，集料箱右移复位推动抵触板偏转挤压齿板向远离T形推板的一侧偏转，进而在复位弹簧伸缩杆复位推力下带动抵触板复位到集料箱内，通过抵触板复位的冲击力将集料箱内的填料推送到上移后夯实块的下侧，通过装置下移，对坡面进行填充并压平。
