Water supply and drainage system of plunge pool

Abstract

The invention discloses a water supply and drainage system of a plunge pool with relatively low energy consumption. The system comprises a water pipe for communicating the plunge pool at the upstream of an afterbay dam and a river bed at the downstream of the afterbay dam, the water pipe is embedded in the dam body of the afterbay dam, the front end of the water pipe is led to a bottom plate of the plunge pool at the upstream of the afterbay dam, and the rear end of the water pipe is led to the river bed at the downstream of the afterbay dam; and the water pipe is provided with a control valve and a pumping device for pumping accumulated water in the plunge pool into the river bed at the downstream of the afterbay dam. The pumping device of the system can pump off the accumulated water in the plunge pool only by endowing each unit weight of accumulated water in the plunge pool with energy for raising the accumulated water to the downstream water level height of the afterbay dam from the bottom of the afterbay dam so that the energy consumption of the pumping device is saved. The water pipe is embedded in the dam body of the afterbay dam to become a permanent facility so as to avoid repeated assembly and disassembly, save the time for assembling and disassembling the pumping facility and gain more time for overhauling of an energy-dissipating building.

Description

technical field [0001] The invention relates to a water supply and drainage system for a hydraulic structure, in particular to a water supply and drainage system for a pad pond. Background technique [0002] When high dams adopt energy dissipation methods such as deflection flow and falling flow energy dissipation, in order to avoid excessive scour pit depth, or the weak structure of the dam foundation may be cut off by the scour pit and endanger the stability of the dam foundation, or the bank slope may be scoured When the stability of the abutment is endangered by the collapse, the downstream anti-scour problem is often solved by setting up secondary dams and water cushion ponds. For example, the invention patent whose authorization notification number is CN101126232B promptly discloses this measure. During the operation of the project, the accumulated water in the water cushion pond must be drained regularly, and the buildings such as the water cushion pond and the secon...

Problems solved by technology

Not only that, for the current pumping and drainage method for the maintenance of pad ponds, temporary pumping pipes and pumping facilities must be installed and dismantled during each maintenance, which takes up valuable maintenance time during the dry period, with a large amount of repetitive work and serious waste of resources. low efficiency
