Flow guiding device for deep and narrow foundation pit graded broken stone backfilling and construction method of flow guiding device
The invention relates to a graded broken stone backfilling flow guide device for a deep and narrow foundation pit and a construction method of the graded broken stone backfilling flow guide device. The device comprises a supporting frame erected at the top of the deep and narrow foundation pit; the backfilling hopper is arranged on the supporting frame; the flow guide pipe is connected with the bottom of the backfilling hopper and is vertically arranged; the buffer cylinders are connected with the bottoms of the flow guide pipes and sequentially connected from top to bottom, top openings of the buffer cylinders are larger than bottom openings of the buffer cylinders, and the bottoms of the buffer cylinders located on the upper portion partially extend into the buffer cylinders located on the lower portion. According to the backfill flow guide device, the flow guide pipe and the buffer cylinder are connected in series, so that the backfill flow guide device can extend into the deep and narrow foundation pit, graded gravel is guided to the bottom of the deep and narrow foundation pit, and an underground water outer wall waterproof protection layer on the side wall of the deep and narrow foundation pit is prevented from being damaged; the multiple buffer cylinders are connected in series, so that the falling speed of the graded broken stone can be reduced, the potential energy of the graded broken stone is reduced, and the graded broken stone is prevented from damaging the finished product process at the bottom of the deep and narrow foundation pit.
本发明涉及一种用于深窄基坑级配碎石回填导流装置及其施工方法，该装置包括：架设于深窄基坑顶部的支撑架；设于支撑架上的回填料斗；与回填料斗的底部连接的且呈竖向设置的导流管；与导流管的底部连接的多个缓冲筒，从上至下依次连接且缓冲筒的顶部开口大于底部开口，位于上部的缓冲筒的底部有部分伸入到位于下部的缓冲筒内。本发明的回填导流装置通过导流管和缓冲筒的串接，能够伸入到深窄基坑内，将级配砂石导流到深窄基坑的底部，避免对深窄基坑侧壁处的地下水外墙防水保护层造成破坏，且缓冲筒顶部开口大于底部开口，多个缓冲筒串接能够起到减缓级配碎石下落速度，减小级配碎石的势能，防止级配碎石对深窄基坑底部处的成品工艺造成破坏。
