Abstract
The utility model is related to a kind of water-conveyance tunnel of utilization reconstruction of diversion tunnel.The purpose of this utility model is to provide a kind of water-conveyance tunnel of simple and effective utilization reconstruction of diversion tunnel, it is intended that reduce new construction scale, cost saving as far as possible.The technical solution of the utility model is：Using the water-conveyance tunnel of reconstruction of diversion tunnel, including original diversion tunnel, its spy is to pour tower intake vertically in the import of diversion tunnel, and the crest level of the tower intake is on Sediment Siltation elevation, under level of dead water elevation；Pre-buried water conveyance steel tube in concrete plug, concrete plug is set inside diversion tunnel, and water conveyance steel tube extends to water conservancy diversion hole outlet.The utility model is applied to middle-size and small-size Hydraulic and Hydro-Power Engineering.
Description
Technical field
The utility model is related to a kind of water-conveyance tunnel of utilization reconstruction of diversion tunnel.Suitable for middle-size and small-size Hydraulic and Hydro-Power Engineering.
Background technology
In the prior art, the inlet of diversion tunnel elevation in Hydraulic and Hydro-Power Engineering is than relatively low, using reconstruction of diversion tunnel into
Newly-built water inlet, water-conveyance tunnel, vertical shaft (or inclined shaft) and diversion tunnel are generally needed using the form of " dragon comes back " during water-conveyance tunnel
Connect, project scale is larger.
The content of the invention
The technical problems to be solved in the utility model is：For above-mentioned situation, there is provided a kind of simple and effective utilization water conservancy diversion
The water-conveyance tunnel of hole reconstruction, it is intended that reduce new construction scale, cost saving as far as possible.
The technical scheme that the utility model is used is：Utilize the water-conveyance tunnel of reconstruction of diversion tunnel, including original water conservancy diversion
Hole, its spy is to pour tower intake vertically in the import of diversion tunnel, and the crest level of the tower intake is high in Sediment Siltation
On journey, under level of dead water elevation；Pre-buried water conveyance steel tube in concrete plug, concrete plug is set inside diversion tunnel, it is defeated
Water steel pipe extends to water conservancy diversion hole outlet.
The centre of the tower intake is water inlet vertical shaft, and water inlet shaft top is equipped with fixed trash rack, diversion tunnel upstream
Side head sets blocking sluice gate of diversion tunnel groove, and tower intake bottom has stiling basin.
Blocking sluice gate of diversion tunnel framed bent is had at the top of the tower intake, with rock ballast between tower intake and massif
Backfill.
The water conveyance steel tube is being provided with maintenance valve and energy dissipating valve close to exit.
The beneficial effects of the utility model are：The utility model scheme is to be reconstructed into water delivery tunnel based on classical diversion tunnel
Hole, tower intake is arranged using in inlet of diversion tunnel；Tower intake crest level is on Sediment Siltation elevation, level of dead water high
Under journey；The pre-buried water conveyance steel tube in newly-built concrete plug, plug in diversion tunnel, steel pipe extends to the side such as water conservancy diversion hole outlet
Method, it is simple, practical, effectively by former reconstruction of diversion tunnel into water-conveyance tunnel, reduce project scale, save construction investment.
Brief description of the drawings

Embodiment
As shown in Figure 1 and Figure 2, the present embodiment utilizes reconstruction of diversion tunnel water-conveyance tunnel, and original diversion tunnel 8 is located in massif,
Gentle dip extends to the abrupt slope 14 in massif downstream.This example is at the import of diversion tunnel 8 with vertical tower of concreting
Water inlet 1, the crest level of the tower intake is on Sediment Siltation elevation, under level of dead water elevation, in tower intake 1
Between fixed trash rack 3 and blocking sluice gate of diversion tunnel framed bent 2 are housed for water inlet vertical shaft 4, water inlet shaft top.In the upper of diversion tunnel 8
Swim side head and blocking sluice gate of diversion tunnel groove 6 is set, stiling basin 7 is had in the bottom of tower intake 1.
As shown in figure 3, the inside of diversion tunnel 8 sets concrete plug 9, and the pre-buried water conveyance steel tube in concrete plug
10, water conveyance steel tube extends to diversion tunnel 8 and exported, and the water conveyance steel tube 10 is being provided with maintenance valve 12 and energy dissipating close to exit
Valve 13.
Backfilled between tower intake 1 and massif with rock ballast 5.
The top of current from tower intake 1 is fallen, and is flowed out after the energy dissipating of stiling basin 7 from diversion tunnel 8, finally from abrupt slope 14
Leak into korneforos.
