Ultra-deep radiation well drainage structure and construction method thereof
The invention discloses an ultra-deep radiation well seepage drainage structure and a construction method thereof. The ultra-deep radiation well seepage drainage structure comprises a radiation well and a large-diameter sand well. The radiation well comprises a vertical shaft and a radiation pipe, the large-diameter sand well comprises an upper sand well and a lower sand well, the large-diameter sand well is located in the vertical shaft, the radiation pipe is located on the peripheral side of the vertical shaft and communicated with the vertical shaft, a water guide pipe is arranged on the side, away from the radiation pipe, of the vertical shaft, and the water guide pipe is communicated with the vertical shaft; by means of the characteristic that the large-diameter sand well can rapidly drain seepage, the large-diameter sand well is excavated in the early stage to rapidly drain seepage and control the height of a seepage line, the problems that sand gushing occurs in the radiation well, well sinking cannot be carried out, the well sinking deviates, and bottom sealing is difficult are solved, and meanwhile the problem that construction cannot be carried out due to sand gushing and other reasons of the ultra-deep radiation well is solved. Through the combination of the large-caliber sand well and the radiation well, the depth of the ultra-deep radiation well reaches 60 m or above, the application range of the radiation well is expanded, and particularly, the application of the radiation well becomes possible in seepage drainage of a high-dam tailing pond.
本发明公开了一种超深辐射井排渗结构及其施工方法，括辐射井和大口径砂井；所述辐射井包括竖井和辐射管，所述大口径砂井包括上砂井和下砂井，所述大口径砂井位于所述竖井内部，所述辐射管位于所述竖井的周侧并与所述竖井连通，所述竖井远离所述辐射管的一侧设有导水管，所述导水管与所述竖井连通；利用大口径砂井能快速排渗的特性，前期开挖大口径砂井快速排渗并控制浸润线高度，防止辐射井出现涌砂、无法沉井、沉井偏移、封底困难等问题，同时解决了超深辐射井由于涌砂等原因导致无法施工的问题。利用大口径砂井与辐射井的组合，使得超深辐射井深度达到60m以上，拓展了辐射井的应用范围，尤其在高坝尾矿库的排渗中使得辐射井的应用成为可能。
