Backfilling device and backfilling method for municipal wet, soft and narrow fertile groove foundation pit
The invention belongs to the technical field of building construction, and particularly relates to a backfilling device and method for a municipal wet, soft and narrow fat groove foundation pit, the backfilling device comprises a hopper, a filtering and screening mechanism is arranged in the hopper, the filtering and screening mechanism comprises a steel wire screen, and soil blocks with proper sizes are filtered through the filtering and screening mechanism; and large soil blocks are screened, and rolling recovery movement is carried out. According to the backfilling device and method for the municipal wet, soft and narrow fertile groove foundation pit, by arranging the filtering and screening mechanism, backfilled soil blocks are screened according to the size, the backfilling density is improved and gaps between the soil blocks are reduced by selecting small soil blocks in a matched mode, and wet, soft and sinking is avoided after follow-up tamping, so that the construction quality is improved, and the construction period is shortened. And through cooperation of a positioning rod, a buffer blade and an arc-shaped buffer block, the rolling speed of the soil blocks during screening is reduced, the qualified soil blocks are fully screened, and therefore the screening quality effect is improved.
本发明属于建筑施工技术领域，尤其是一种市政湿软狭窄肥槽基坑用回填装置及回填方法，包括料斗，料斗的内部设置有过滤筛选机构，过滤筛选机构包括钢丝筛网，通过过滤筛选机构对适量大小的土块进行过滤，并对较大的土块实现筛选进行滚动回收运动。该市政湿软狭窄肥槽基坑用回填装置及回填方法，通过设置过滤筛选机构，起到对回填的土块大小进行筛选，通过选用较小的土块配合提高回填的密度，减小土块之间的空隙，后续夯实后避免了出现湿软下沉，从而提高施工质量，并通过定位杆、缓冲叶片与弧形缓冲块的配合降低土块在筛选时的滚落速度，充分的对合格的土块进行筛选，从而提高了筛选质量的效果。
