Intelligent regulation and control drainage system and method for valley type slag yard

LI JINCHAO

The invention discloses an intelligent regulation and control drainage system and method for a valley type slag yard, and belongs to the technical field of slag yard drainage. A water collecting pool is arranged at the downstream of a valley; the multiple wells are excavated at the upstream of the valley, and the bottoms of the wells extend into the ground of the valley and are at least lower than the bottom elevation of the slag yard; at least one siphon and one liquid level sensor are inserted into each well; a water outlet of the siphon extends to the water collecting tank and is provided with an electromagnetic valve; a siphon opening of the siphon is at least a preset height lower than the water outlet; and the controller performs opening and closing control and opening degree control on the electromagnetic valve according to the liquid level, detected by the liquid level sensor, in the well. Construction can be conducted after the slag yard is built, the built flood guide channel or the flood drainage channel cannot be affected, when the flood guide channel or the flood drainage channel or an underground water guide and drainage layer at the bottom of the slag yard loses efficacy, flood or underground seepage water can be timely and rapidly drained to a catchment pool on the upstream of a valley through the siphon principle, and the slag yard is protected.

本发明公开了一种用于山谷型渣场的智能调控排水系统及方法，属于渣场排水技术领域。本发明在山谷的下游设置汇水池；多口井开挖在山谷的上游，井的底部伸入山谷的地面以下至少低于渣场底部高程；每口井中至少插有一根虹吸管和一个液位传感器；虹吸管的出水口延伸至汇水池并设有电磁阀；虹吸管的虹吸口低于出水口至少预设高度；控制器根据液位传感器检测的井中的液位对电磁阀进行开闭控制及开度控制。本发明能够在渣场建成以后施工，也不会影响已经建成的导洪渠或者排洪道，在导洪渠、排洪道或者渣场底部地下水导排层失效时，能够在山谷的上游及时、快速地通过虹吸原理把洪水或地下渗水排到汇水池，使渣场得到保护。
