Abstract
The utility model discloses a kind of massif Inner guide hole gate shaft structure, comprise Diversion Tunnel and be arranged on the pit shaft in massif, gate is provided with in pit shaft, headstock gear operating room is provided with in massif and at the top of pit shaft, gate slot is provided with in the below of pit shaft in Diversion Tunnel, the aperture place at gate slot top is provided with temporary plugging cover plate, gate shaft is arranged in the massif of Diversion Tunnel barrel section by the utility model, for embedded (cavern) gate shaft, the pit shaft that this embedded (cavern) gate shaft effectively can overcome the existence of outdoor formula gate shaft is very high, road arrangement difficulty, engineering quantity and the investment shortcoming such as large.Meanwhile, by being arranged on the temporary plugging cover plate in gate shaft, block river and enter gate shaft, can effectively reduce gate shaft pit shaft height, while height reduction, decrease investment, reduce cost, construction is simple, and cost is low.
Description
Technical field
The utility model relates to a kind of massif Inner guide hole gate shaft structure, belongs to Hydraulic and Hydro-Power Engineering technical field.
Background technology
At present, general in Hydropower Station Construction by the entrance location place of Diversion Tunnel gate locating at Diversion Tunnel, be outdoor formula gate shaft, its geological conditions is bright and clear, without underground construction, and comparatively safe ready of constructing.But simultaneously because riverbed water level of passing the flood period is very high, for ensureing that riverbed water level of passing the flood period does not flood headstock gear operating room on gate shaft, it is very high that the pit shaft of outdoor formula gate shaft must be built, engineering quantity and investment large; The bank slope of adding due to inlet of diversion tunnel position is steep, go the road arrangement difficulty of gate shaft, therefore build outdoor formula gate shaft in inlet of diversion tunnel position, have that pit shaft is very high, road arrangement is difficult, engineering quantity and the large problem of investment, so existing Diversion Tunnel gate shaft structure is still perfect not.
Utility model content
The purpose of this utility model is: provide that a kind of structure is simple, safe and reliable, cost is low, hold easy working embedded (cavern) gate shaft structure, and by being arranged on the temporary plugging cover plate in gate shaft, block river and enter gate shaft, can prevent the current pit shaft that overfills from jeopardizing headstock gear operating room safety thus a kind of massif Inner guide hole gate shaft structure of Diversion Tunnel cavern gate shaft height can be reduced, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of massif Inner guide hole gate shaft structure, comprise Diversion Tunnel and be arranged on the pit shaft in massif, gate is provided with in pit shaft, headstock gear operating room is provided with in massif and at the top of pit shaft, in Diversion Tunnel, be provided with gate slot in the below of pit shaft, the aperture place at gate slot top is provided with temporary plugging cover plate.
Described temporary plugging cover plate is detachable.
Owing to have employed technique scheme, compared with prior art, gate shaft is arranged in the massif of Diversion Tunnel barrel section by the utility model, for embedded (cavern) gate shaft, this embedded (cavern) gate shaft effectively can overcome that the pit shaft that outdoor formula gate shaft exists is very high, road arrangement is difficult, engineering quantity and the shortcoming such as investment is large.Meanwhile, by being arranged on the temporary plugging cover plate in gate shaft, block river and enter gate shaft, can effectively reduce gate shaft pit shaft height, while height reduction, decrease investment, reduce cost, construction is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: 1-headstock gear operating room, 2-pit shaft, 3-gate, 4-gate slot, 5-temporary plugging cover plate, 6-Diversion Tunnel.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment of the present utility model: a kind of massif Inner guide hole gate shaft structure, the pit shaft 2 comprising Diversion Tunnel 6 and be arranged in massif, gate 3 is provided with in pit shaft 2, in massif the top of pit shaft 2 is provided with headstock gear operating room 1, in Diversion Tunnel 6, be provided with gate slot 4 in the below of pit shaft 2, the aperture place at gate slot 4 top is provided with temporary plugging cover plate 5.
Described temporary plugging cover plate 5 is detachable.
The utility model headstock gear operating room 1, pit shaft 2, gate 3, gate slot 4 are based upon in massif.
Pit shaft 2 and gate 3 are arranged in the massif at barrel fragment position place of Diversion Tunnel 6;
Position of platform, aperture on gate slot 4 arranges temporary plugging cover plate 5, temporary plugging cover plate 5 is made to seal up the aperture at gate slot 4 top, the safety of headstock gear operating room 1 is jeopardized in the upper end preventing the current of Diversion Tunnel 6 from completely arriving pit shaft 2, thus effectively reduce gate shaft pit shaft height, while height reduction, decrease investment, reduce cost, construction is simple, and cost is low
Described temporary plugging cover plate 5 is detachable apparatus, when gate 3 needs lower lock, selects under the non-full stream mode of Diversion Tunnel 6, removes temporary plugging cover plate 5, then normally puts down gate 3.
Specific operation process is as follows: the construction 1, first completing the headstock gear operating room 1 of Diversion Tunnel 6 in massif and gate shaft, pit shaft 2, gate 3, gate slot 4 according to design parameters.
2, temporary plugging cover plate 5 is installed at position of platform, the aperture place on gate slot 4, makes temporary plugging cover plate 5 seal up the aperture at gate slot 4 top.
3, the normal overcurrent of Diversion Tunnel 6.When gate 3 needs lower lock time, select under the non-full stream mode of Diversion Tunnel 6, remove temporary plugging cover plate 5, then normally put down gate 3.
