Self-flowing drainage system of water diversion tunnel maintenance channel of pumped storage power station
The invention discloses a self-flowing drainage system of a water guiding horizontal tunnel maintenance channel of a pumped storage power station. The self-flowing drainage system comprises a maintenance channel drainage ditch, a drainage steel pipe, a water collecting well and a drainage tunnel. Underground water in the diversion level tunnel maintenance channel can automatically flow through drainage ditches in the two sides of the maintenance channel bottom plate and be collected into the water collecting well, and leakage water of the diversion level tunnel maintenance channel permanent blocking body can automatically flow through drainage steel pipes embedded in the lower portion of the hollow gallery bottom plate of the permanent blocking body and be collected into the water collecting well. The water collecting well is located at the tail end of the maintenance channel permanent plugging body and connected with the gravity drainage tunnel arranged along the slope. And underground water collected in the water collecting well can be drained to a natural channel outside the hole through the self-flowing drainage hole. The invention is suitable for the water-guiding horizontal tunnel maintenance channel of the pumped storage power station with the condition of arranging the self-flowing drainage tunnel, and aims to utilize gravity self-flowing drainage without investment of mechanical pumping drainage equipment, so that the cost of equipment operation maintenance and manual maintenance is reduced, the energy consumption of the equipment is reduced, and emergencies such as equipment failure and power failure can be effectively handled; and the reliability of the overhaul channel drainage system is improved.
本发明公开一种抽水蓄能电站引水平洞检修通道的自流排水系统，包括检修通道排水沟、排水钢管、集水井和排水洞。引水平洞检修通道内的地下水可通过检修通道底板两侧的排水沟自流汇集于集水井内，引水平洞检修通道永久封堵体的渗漏水可通过预埋于永久封堵体空心廊道底板下部的排水钢管自流汇集于集水井内；集水井位于检修通道永久封堵体末端，并与顺坡布置的自流排水洞相连；集水井内汇集的地下水可通过自流排水洞排至洞外天然沟道。本发明适用于具备布置自流排水洞条件的抽水蓄能电站引水平洞检修通道，旨在利用重力自流排水，无需投入机械抽排设备，减少了设备运行维护和人工检修的成本，减少了设备的能源消耗，并可有效应对设备故障和停电等突发情况，提高了检修通道排水系统的可靠性。
