Abstract
The utility model provides a flood discharge tunnel water inlet structure reconstructed by diversion tunnels, which comprises a flood discharge tunnel; the flood discharge emptying hole comprises a flood discharge emptying hole body and a flood discharge emptying hole water inlet arranged at one end of the flood discharge emptying hole body, and the flood discharge emptying hole water inlet is a vertical water inlet; the flood discharge emptying tunnel is characterized in that a flood discharge emptying tunnel gate is arranged on the flood discharge emptying tunnel body, and a diversion tunnel plugging concrete plug, a diversion tunnel plugging gate and a diversion tunnel water inlet are sequentially arranged on one side of the flood discharge emptying tunnel water inlet. The utility model discloses reform transform traditional horizontal water inlet into vertical water inlet, its structure is simple relatively, during the construction, receives the upper reaches water level influence less relatively, has reduced the construction interference, and not only the transformation work volume is less relatively, has reduced the construction degree of difficulty that the diversion tunnel was rebuilt into the flood discharge tunnel import simultaneously for the construction progress.
Description
Technical field
The utility model relates to a kind of flood discharging tunnel water inlet structures by reconstruction of diversion tunnel, belong to hydraulic and hydroelectric engineering technology
Field is related to the water inlet structure of the flood discharging tunnel of reservoir spillway building construction more particularly to reservoir reconstruction of diversion tunnel, is suitable for
The structures such as most of rebuilding conduit into flood release tunnel.
Background technique
During reservoir construction, it is usually permanent flood discharging tunnel by construction time temporay building reconstruction of diversion tunnel, can reduces
Project amount and reduction construction investment.
At present in reconstruction, usually excavates diversion tunnel first section tunnel and rearrange water inlet, therefore have centainly
Difficulty of construction, for medium and small reservoirs, permanent flood discharging tunnel input elevation and inlet of diversion tunnel elevation height difference are smaller,
Traditional digging mode is long in time limit and construction technical requirement is high.
A kind of structure that diversion tunnel and flood discharging tunnel as disclosed in the Chinese patent application No. is 2015206000560 combine,
A kind of simple, the easy for construction Diversion & Flood-discharge Cave structure of structure disclosed in Chinese patent application No. is 2011200297128, Shen
Please a kind of reservoir diversion tunnel backfill reconstruction flood discharging tunnel disclosed in the Chinese patent number for 2014201781598 structure, lead
The structure that reconstruction flood discharging tunnel in stream hole is combined, all avoids secondary excavation flood discharging tunnel, reduces difficulty of construction and cost, shorten
Construction period.But the application, in the stem of diversion tunnel and flood discharging tunnel, water inlet portion structure is combined transformation, improved to let out
Hongdong water inlet structure is vertical direction, i.e., traditional horizontal water inflow mouth is transformed into vertical water inlet, and structure is relatively easy,
Structure construction influenced by upstream water level it is relatively small, construction interference reduce, not only improvement project amount is relatively small, reduces simultaneously
Reconstruction of diversion tunnel accelerates construction speed at the difficulty of construction of flood discharging tunnel import.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of flood discharging tunnel water inlet knot by reconstruction of diversion tunnel
Traditional horizontal water inflow mouth should be transformed into vertical water inlet, structure by the flood discharging tunnel water inlet structure of reconstruction of diversion tunnel by structure
It is relatively easy, structure construction influenced by upstream water level it is relatively small, construction interference reduce, not only improvement project amount is relatively small,
Reconstruction of diversion tunnel is reduced into the difficulty of construction of flood discharging tunnel import simultaneously, accelerates construction speed.
The utility model is achieved by the following technical programs.
A kind of flood discharging tunnel water inlet structure by reconstruction of diversion tunnel provided by the utility model, including flood discharge emptying tunnel；It lets out
Big vast emptying tunnel includes flood discharge emptying tunnel barrel and the flood discharge emptying tunnel water inlet that flood discharge emptying tunnel barrel one end is arranged in, and flood discharge is put
Empty water inlet is vertical water inlet；The flood discharge emptying tunnel barrel is equipped with flood discharge emptying tunnel gate, the water inlet of flood discharge emptying tunnel
The side of mouth is successively arranged blocking concrete for diversion tunnel plug, blocking sluice gate of diversion tunnel, diversion tunnel water inlet.
The flood discharge emptying tunnel water inlet and the radian of flood discharge emptying tunnel barrel junction are 90 °~135 °.
The blocking concrete for diversion tunnel plug with a thickness of 175~1050cm.
The distance between the diversion tunnel water inlet and flood discharge emptying tunnel water inlet are 550~1120cm.
The utility model has the beneficial effects that: traditional horizontal water inflow mouth is transformed into vertical water inlet, structure
It is relatively easy, it when construction, is influenced by upstream water level relatively small, reduces construction interference, not only improvement project amount is relatively small,
Reconstruction of diversion tunnel is reduced into the difficulty of construction of flood discharging tunnel import simultaneously, accelerates construction speed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the sectional view of the utility model Parallel to the flow direction；
Fig. 3 is the enlarged drawing at Fig. 2 a；
In figure: 1- flood discharge emptying tunnel water inlet, 2- diversion tunnel water inlet, 3- blocking sluice gate of diversion tunnel, 4- diversion tunnel block
Concrete plug, 5- ground line, 6- water inlet excavation contour line, 7- flood discharge emptying tunnel barrel, 8- flood discharge emptying tunnel gate.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in FIG. 1 to 3, a kind of flood discharging tunnel water inlet structure by reconstruction of diversion tunnel, including flood discharge emptying tunnel is (by leading
Stream hole is transformed)；Flood discharge emptying tunnel includes flood discharge emptying tunnel barrel 7 and the flood discharge that 7 one end of flood discharge emptying tunnel barrel is arranged in
Emptying tunnel water inlet 1, flood discharge emptying tunnel water inlet 1 are vertical water inlet；The flood discharge emptying tunnel barrel 7 is vented equipped with flood discharge
Hole gate 8, the side of flood discharge emptying tunnel water inlet 1 be successively arranged blocking concrete for diversion tunnel plug 4, blocking sluice gate of diversion tunnel 3,
Diversion tunnel water inlet 2.
The flood discharge emptying tunnel water inlet 1 and the radian of 7 junction of flood discharge emptying tunnel barrel are 90 °~135 °.
The blocking concrete for diversion tunnel plug 4 with a thickness of 175~1050cm.
The distance between the diversion tunnel water inlet 2 and flood discharge emptying tunnel water inlet 1 are 550~1120cm.
Further, this structure setting needs first to excavate out water inlet excavation contour line in ground line 5 hereinafter, when constructing
6。
Traditional horizontal water inflow mouth is transformed into vertical water inlet by the utility model, and structure is relatively easy, and structure is applied
Work influenced by upstream water level it is relatively small, construction interference reduce, not only improvement project amount is relatively small, while reducing diversion tunnel
The difficulty of construction for reconstructing into flood discharging tunnel import, accelerates construction speed.
