Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering technical field, relates in particular to a kind of power station in river channel structure.
Background technology
Big-and-middle-sized river often have flood discharge large, have features such as navigation requirement.While developing its hydraulic power potentials, in the situation that power station utilized head is high, (conventionally below 40m), does not adopt power house in river channel mostly, as Navigation & Hydropower Junction Engineering engineerings such as the new policies of being built on Jia Lingjiang River, Jinxi, Sha Xi, careless streets.Take Jia Lingjiang River as example, its flood has the advantages that peak height amount greatly, suddenly rises and suddenly falls, and multi-purpose project dam site section is often in Canyon Area, and river course is wide not, outlet structure escape works discharge capacity be need to increase as much as possible, upstream, dam flood control object pressure of flood and submerge loss alleviated.
Because Power Plant, ship lock, sluice, scouring sluice etc. all need to occupy river course, the width in riverbed becomes extremely limited resource, need to reduce the shared riverbed of the non-flood releasing structure width such as block power plant factory building, ship lock as far as possible, and hinge flood discharge building is arranged on main stem to guarantee that hinge has enough flood carrying capacities as far as possible.In addition, for ease of the operational management of Navigation & Hydropower Junction Engineering, ship lock and factory building adopt with bank arrangement more.
Addressing the above problem at present implementation is: reduce the thickness of the structures self such as power house in river channel, ship lock, sluice, scouring sluice as far as possible, or dig riverbank, both sides, or the flood discharge efficiency of raising flood releasing structure etc.
Use functional requirement due to powerhouse of hydropower station, ship lock, sluice, scouring sluice etc., himself structure is comparatively complicated, the structural thickness that can reduce is limited, the poor effect that often causes structure optimization, if and structural thickness reduces too much, can cause again the increase of structural reinforcement amount, Structural Endurance Problem, economic effect is not obvious.And dig riverbank, both sides, and when excavation and support engineering amount increase considerably, also can bring stability of high slope problem, claim for eot and project occupation of land increase problem, be unfavorable for performance and the environmental protection of engineering safety, economic benefit.
The terminological interpretation of the utility model part is as follows
Ship lock: utilize in the navigation channel that has gate to control to two ends and fill with, sluice, with lifting water level, make boats and ships can overcome the shape navigation structure, railway carriage or compartment of the concentrated height of water on navigation channel, claim again by " railway carriage or compartment ship lock ".By lock chamber, lock head, gate, approach channel and relevant device, formed.When ship is up, first lock chamber is sluiced, treat that indoor water level flushes with the level of tail water, open lower gate, allow ship enter lock chamber, close immediately lower gate, to lock chamber, pour water, when the lock chamber water surface and upper pond level flush, open upstream gate, ship rolls lock chamber away from, enters Upstream Navigation Waterway.Contrary when descending.
Power station in river channel's factory building: powerhouse of hydropower station is arranged in riverbed, itself also plays dash effect, as Gezhou Dam powerhouse of hydropower station.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of and can save the layout that riverbed width is beneficial to flood releasing structure, and power station in river channel's structure of implementing of good economy performance, constructability.
For addressing the above problem the technical scheme of employing, be: power station in river channel's structure comprises ship lock and the factory building clipping room of adjacent setting, ship lock comprises spaced twice ship lock abutment wall, and ship lock abutment wall comprises upper approach channel abutment wall, head bay abutment wall and the lock chamber abutment wall setting gradually along river flow direction; Between twice ship lock abutment wall, form lock chamber, lock chamber bottom is lock floor; A monolith three of the head bay abutment wall of close factory building clipping room side, part lock chamber abutment wall, factory building clipping room makes and is integrally formed co-ordinative construction; Or, making, a monolith of the lock chamber abutment wall of part, part approach channel abutment wall, factory building clipping room is integrally formed co-ordinative construction near the head bay abutment wall of factory building clipping room side.
Further: co-ordinative construction and have neither part nor lot between the upper approach channel abutment wall that forms co-ordinative construction and be provided with structural joint, co-ordinative construction and have neither part nor lot between the lock chamber abutment wall that forms co-ordinative construction and be provided with structural joint, is provided with structural joint between co-ordinative construction and lock floor.
Further: co-ordinative construction bottom is provided with chamfering.
Further: near side slope and the basis of ship lock and factory building clipping room side, all (vertical: gradient excavation level) by 1:0～1:0.1.
Further: ship lock axis and factory building clipping room longitudinal axis intersect.
Further: ship lock axis is vertical with factory building clipping room longitudinal axis.
The beneficial effects of the utility model are: a monolith of (1), ship lock part abutment wall and factory building clipping room is made and is integrally formed co-ordinative construction, and this co-ordinative construction realizes the function of ship lock and factory building clipping room simultaneously, and can realize dam crest communication function.Than the technical scheme of arranging separately factory building clipping room and ship lock, obviously reduced shared riverbed overall width, be conducive to the layout of hinge flood releasing structure and reduce inundation loss of reservoir.
(2), a monolith of ship lock part abutment wall and factory building clipping room makes and is integrally formed co-ordinative construction, more easily meets structural strength, antiskid, anti-ly inclines, the requirement such as anti-floating, can significantly save excavated volume and concrete amount.
Accompanying drawing explanation
Tu1Shi power station in river channel structure top view;
Fig. 2 is the A-A sectional view of Fig. 1;
In figure, be labeled as: upper approach channel abutment wall 1, head bay abutment wall 2, lock chamber abutment wall 3, lock chamber 4, structural joint 5, factory building clipping room 6, co-ordinative construction 7, lock floor 8.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Power station in river channel's structure, comprises ship lock and the factory building clipping room 6 of adjacent setting, and ship lock comprises spaced twice ship lock abutment wall, and ship lock abutment wall comprises upper approach channel abutment wall 1, head bay abutment wall 2 and the lock chamber abutment wall 3 setting gradually along river flow direction; Between twice ship lock abutment wall, form lock chamber 4, lock chamber 4 bottoms are lock floor 8; A monolith three of the head bay abutment wall 2 of close factory building clipping room 6 sides, part lock chamber abutment wall 3, factory building clipping room 6 makes and is integrally formed co-ordinative construction 7; Or, making, a monolith of the lock chamber abutment wall 3 of part, part approach channel abutment wall 1, factory building clipping room 6 is integrally formed co-ordinative construction 7 near the head bay abutment wall 4 of factory building clipping room 6 sides.Ship lock axis can intersect with factory building clipping room 6 longitudinal axis or be vertical.
