Abstract
The present invention provides a kind of flood discharging tunnel water inlet structures by reconstruction of diversion tunnel, including flood discharge emptying tunnel；Flood discharge 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 emptying tunnel water inlet is vertical water inlet；The flood discharge emptying tunnel barrel is equipped with flood discharge emptying tunnel gate, and the side of flood discharge emptying tunnel water inlet is successively arranged blocking concrete for diversion tunnel plug, blocking sluice gate of diversion tunnel, diversion tunnel water inlet.Traditional horizontal water inflow mouth is transformed into vertical water inlet by the present invention, its structure is relatively easy, when construction, it is influenced by upstream water level relatively small, reduce construction interference, not only improvement project amount is relatively small, while reducing reconstruction of diversion tunnel into the difficulty of construction of flood discharging tunnel import, accelerates construction speed.
Description
Technical field
The present invention relates to a kind of flood discharging tunnel water inlet structures by reconstruction of diversion tunnel, belong to hydraulic and hydroelectric engineering technology neck
Domain 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 big
The structures such as part 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.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of flood discharging tunnel water inlet structure by reconstruction of diversion tunnel, it should
Traditional horizontal water inflow mouth is transformed into vertical water inlet by the flood discharging tunnel water inlet structure of reconstruction of diversion tunnel, structure is relatively simple
Singly, structure construction is influenced relatively small by upstream water level, and construction interference is reduced, and not only improvement project amount is relatively small, drops simultaneously
Low difficulty of construction of the reconstruction of diversion tunnel at flood discharging tunnel import, accelerates construction speed.
The present invention is achieved by the following technical programs.
A kind of flood discharging tunnel water inlet structure by reconstruction of diversion tunnel provided by the invention, including flood discharge emptying tunnel；Flood discharge is put
Cavity 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, flood discharge emptying tunnel
Water inlet is vertical water inlet；The flood discharge emptying tunnel barrel is equipped with flood discharge emptying tunnel gate, flood discharge emptying tunnel water inlet
Side 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 beneficial effects of the present invention are: traditional horizontal water inflow mouth is transformed into vertical water inlet, structure is opposite
Simply, when construction, influenced by upstream water level it is relatively small, reduce construction interference, not only improvement project amount is relatively small, simultaneously
Reconstruction of diversion tunnel is reduced into the difficulty of construction of flood discharging tunnel import, accelerates construction speed.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the sectional view of Parallel to the flow direction of the present invention；
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 technical solution of the present invention, 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 present invention, and structure is relatively easy, structure construction by
Upstream water level influence is relatively small, and construction interference is reduced, and not only improvement project amount is relatively small, while reducing reconstruction of diversion tunnel
At the difficulty of construction of flood discharging tunnel import, construction speed is accelerated.
