Rigid and flexible plugging method for water in flood drainage channel of tailing pond
The invention discloses a rigid and flexible plugging method for water in a tailing pond flood drainage channel, a grouting plugging section (8), a flexible plugging body section and a permanent structure plugging body section are respectively and continuously arranged in the tailing pond flood drainage channel from inside to outside, and the permanent structure plugging body section is composed of a concrete section (7) and retaining walls (5) respectively positioned on two sides of the concrete section (7). A section of inverted filter (1) which is not less than 1m is arranged on the upstream of the permanent structure plugging body section, and grouting is performed in a flood drainage channel by adopting cement tail mortar in a segmented manner through three pre-buried grouting pipes (4) with different lengths, so that a grouting plugging section (8) is formed. According to the rigid and flexible plugging method for the water in the flood drainage channel of the tailings pond, the principle of first dredging and then plugging is effectively applied, the method is simple, the practicability is high, the plugging speciality is high, the construction cost is low, the operation safety of the tailings pond can be guaranteed, and potential safety hazards caused by plugging failure of a flood drainage system are avoided.
本发明公开了一种尾矿库排洪通道带水的刚性加柔性封堵方法，在尾矿库排洪通道自内向外分别连续设置注浆封堵段(8)、柔性封堵体段、永久性结构封堵体段，所述的永久性结构封堵体段由混凝土段(7)、分别位于混凝土段(7)两侧的挡墙(5)构成。在永久性结构封堵体段的上游设置一段不小于1m的反滤层(1)，通过预埋的3根长度不一的注浆管(4)，采用水泥尾砂浆在排洪通道内分段进行注浆，形成注浆封堵段(8)。本发明的一种尾矿库排洪通道带水的刚性加柔性封堵方法有效运用“先疏后堵”的原理，方法简单，实用性高，封堵专业性强，工程造价低，可以保障尾矿库的运行安全，避免因排洪系统封堵失效带来的安全隐患。
