Description
Technical Field
The utility model belongs to the technical field of the ecological drainage technique of water conservancy pivot and specifically relates to a diversion tunnel import pylon bypass structure for ecological drainage is related to.
Background
In recent years, with the increasing social demand, the development and utilization of natural resources in China are gradually enhanced, and the construction of hydraulic engineering such as river-blocking gate dams, reservoirs and the like not only changes the evolution law of river morphology and riverbed landform, but also changes the downstream hydrological flow and flow state, thereby causing the ecological crisis of rivers, and the concrete manifestations of the overall ecological function weakening of the rivers, reduction of biological diversity and the like are realized. Increasingly fragile river ecological environment seriously restricts sustainable development of water resources and water environment, and becomes a bottleneck restricting human survival and social development. With the increasing destruction of ecological and environmental resources, the problem of river ecological flow begins to be gradually concerned. The ecological flow is ensured to a certain extent, and the ecological water quality improving method has great significance for improving water ecology. The determination of reasonable ecological water demand and the implementation of ecological base flow discharge guarantee measures are the fundamental premise for slowing down the ecological influence of hydraulic engineering, so that the existing reservoir hubs are all matched with and built with ecological base flow permanent facilities. However, in the reservoir engineering, in order to maintain the basic form and ecological function of the downstream river and prevent the river from cutting off during the period that the diversion tunnel is down-gated and the reservoir water level is not stored to the application water level of the ecological basic flow permanent facility, the river ecological requirements are analyzed to determine the discharge flow, and the reasonable temporary ecological basic flow guarantee facility is built by combining with the engineering arrangement.
Disclosure of Invention
The utility model provides a diversion tunnel import pylon bypass structure for ecological drainage, aim at solve under the diversion tunnel floodgate, ecological basic flow permanent facility not yet maintain the problem of low reaches river basic morphology and ecological function during operation yet.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
diversion tunnel import tower frame bypass structure for ecological drainage, including diversion tunnel's side mound and shutoff gate, still include
The drainage part comprises an ecological overflowing valve chamber arranged outside the side pier, an ecological overflowing pipe arranged in parallel with the water flow direction is arranged in the ecological overflowing valve chamber in a penetrating mode, one end of the ecological overflowing pipe is communicated with the upstream of a river, the other end of the ecological overflowing pipe extends into the side pier at the downstream of the plugging gate and is communicated with the downstream of the river through a diversion tunnel, and an electric control valve positioned in the ecological overflowing valve chamber is further arranged on the ecological overflowing pipe;
and the maintenance part comprises a vertical shaft arranged at the top of the ecological overflow valve chamber, and the top of the vertical shaft is provided with a sealing cover plate.
And mounting holes for penetrating the ecological overflowing valve are formed in the side wall of the ecological overflowing valve chamber and the side pier at the downstream of the plugging gate.
And the side wall of the vertical shaft is provided with a ladder stand.
The utility model provides a diversion tunnel import pylon bypass structure for ecological drainage, simple structure, the construction of being convenient for, operation and maintenance are all very convenient. Compared with the prior art, the method has the following advantages:
(1) the ecological base flow is led to the tail end of the water inlet tower frame by additionally arranging the ecological base flow valve chamber and the bypass steel pipe positioned in the ecological base flow valve chamber on the side face of the water inlet tower frame of the diversion tunnel, and the ecological base flow is discharged to a downstream river channel by utilizing the diversion tunnel section, so that the method is simple, the construction is convenient, and the engineering investment can be saved;
(2) the purposes of opening, closing and regulating the flow of the raw base flow are achieved by remotely operating the electric control valve in the ecological base flow valve chamber, and the management and the operation are very convenient;
(3) the top of the ecological base flow valve chamber is provided with the people inlet vertical shaft, if equipment failure occurs in the drainage operation process, a maintainer can overhaul the ecological base flow valve chamber through the people inlet vertical shaft, the operation is very convenient, the investment of the people inlet vertical shaft is small, and a layer of powerful guarantee can be added for the continuous flow of the ecological base flow.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in figures 1-3, a diversion tunnel import tower bypass structure for ecological drainage, including side pier 1 and shutoff gate 2, still include drainage portion and maintenance portion. Specifically, the drainage part comprises an ecological overflow valve chamber 3 positioned outside the side pier 1, and is constructed simultaneously with the diversion tunnel inlet tower. The side wall of the ecological overflow valve chamber 3 and the side pier 1 at the downstream of the plugging gate 2 are provided with mounting holes for penetrating the ecological overflow pipe 4 arranged in parallel with the water flow direction. The ecological overflow pipe 4 is usually made of steel pipe, one end of which is communicated with the upstream of the river, and the other end of which is communicated with the downstream of the river after passing through a mounting hole arranged on the side pier 1 at the downstream of the plugging gate 2, so as to form a bypass pipeline. And the ecological overflow pipe 4 passes through the mounting hole and then seals the gap of the mounting hole by using concrete. An electric control valve 5 is also arranged on the ecological overflow pipe 4 and is positioned in the ecological overflow valve chamber 3, and the electric control valve 5 can be remotely controlled. In order to conveniently overhaul the electric control valve 5, a vertical shaft 6 is built at the top of the ecological overflow valve chamber 3, a sealing cover plate 7 is installed at the top of the vertical shaft 6, and a ladder stand is installed on the side wall.
When the diversion tunnel is used for water storage, the water level in the reservoir area is not stored to the water level of the ecological basic flow permanent facility application, and no other ecological basic flow guarantee measures exist, the electric control valve 5 in the ecological overflow valve chamber 3 is opened through remote operation, and the ecological base flows through a bypass pipeline formed by the ecological overflow pipes 4 and is led to the tail end of the diversion tunnel water inlet tower frame, and then is drained to a downstream river channel through the diversion tunnel. In the operation process, if equipment fails, a maintainer can overhaul the ecological overflow valve chamber 3 through the ladder stand of the people inlet vertical shaft 7. When the reservoir water level rises to a certain height and the ecological base flow does not need to be discharged through the ecological overflow valve chamber 3 any more, the electric control valve 5 is closed.
