Abstract
The utility model discloses a novel spillway gate pier structure. The novel spillway gate pier structure comprises a gate pier body and a bracket, and multiple long strip-shaped grooves and multiple short strip-shaped grooves are alternatively distributed in the side surface of the gate pier body with the bracket as a center in a sector shape. Strip-shaped reinforcement parts are fixed in the long strip-shaped grooves and the short strip-shaped grooves and matched with the long strip-shaped grooves and the short strip-shaped grooves in size. In the work process, the novel spillway gate pier structure is stressed reasonably and short in construction time and low in requirement for construction space, construction equipment and construction environment, greatly reduces gate pier reinforcement cost, improves maintaining efficiency of the gate pier, has high practical value and is suitable for the engineering fields of water conservation, hydropower, traffic and construction.
Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering technical field, relates in particular to a kind of novel spillway pier structure.
Background technology
Hydraulic and Hydro-Power Engineering gate pier produces cracking, and crack not only causes the inner corrosion of steel bar of gate pier, and may cause gate pier structural failure, causes whole excessive big vast building destruction, threatens engineering safety.Along with the development of water conservancy and hydropower cause, both at home and abroad gate pier structure is had higher requirement technically at present: the fan-shaped local tensile reinforcement section area of the local tensile region of (1) gate pier must meet standard (DL/T 5057-2009) requirement; (2) Crack Control of the local tensile region of gate pier must meet standard (DL/T 5057-2009) requirement.
Spillway pier has unique loading characteristic: bracket bears huge concentrated force that backwater gate passes over etc.Under concentrated force effect, gate pier (especially thin-walled gate pier) can produce certain distortion, and gate pier is producing tensile region in a big way.The practice of gate pier operation both at home and abroad shows, passes over concentrated force larger in the situation that at gate, and gate pier distortion is large, is easy to cause concrete in tension zone cracking, affects gate pier and normally uses, destruction gate periphery working environment.At present, have a kind of by the method for affixing steel plate reinforcement reinforced concrete structure, the method is at reinforced concrete structure surface affixing steel plate, owing to being subject to technical restriction, gate pier in the inapplicable Hydraulic and Hydro-Power Engineering of this reinforcement means, because: the concentrated force effect that (1) gate pier is passed over by gate, the direction of gate pier tensile region tensile stress is centered by bracket, to present fan-shaped distribution; (2) gate pier external surface affixing steel plate can affect the keying operation of gate.
Utility model content
For solving problems of the prior art, the utility model is according to spillway pier loading characteristic, based on mechanics basic principle, and the novel spillway pier structure that provides a kind of supporting capacity to be improved.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
Novel spillway pier structure, comprises gate pier main body and bracket, and gate pier main body side surface offers the some bar shaped elongated slots and the short groove of bar shaped that centered by bracket, are fan-shaped distribution, and described bar shaped elongated slot and the short groove of bar shaped are alternately distributed; In the short groove of bar shaped elongated slot and bar shaped, be fixed with the bar shaped girth member of size coupling.
Above-mentioned bar shaped girth member is steel plate bar.
Above-mentioned bar shaped girth member is covered with overcoat.Described overcoat is cement mortar overcoat or polymer mortar overcoat.
Above-mentioned bar shaped girth member is fixed in bar shaped elongated slot and the short groove of bar shaped by cementing agent or bolt.
Compared with prior art, the utlity model has following advantage:
1, bar shaped girth member is conducive to increase gate pier rigidity, reduces gate pier distortion, avoids gate pier structure crack.
2, the fan-shaped layout of bar shaped girth member, can give full play to the effect of steel plate materials.
3, bar shaped girth member is arranged in gate pier side surface bar-shaped trough, is conducive to bar shaped girth member and original gate pier structure is born the point load that gate passes over jointly, improves the supporting capacity of gate pier.
4, bar shaped girth member is arranged in gate pier side surface bar-shaped trough, and gate is moved without any impact.
5, the engineering time short, at the bottom of construction space, equipment and environmental requirement.
Accompanying drawing explanation
Fig. 1 is the concrete structure schematic diagram of the utility model spillway pier structure.
In figure, 1-gate pier main body; 2-bracket; 3-bar shaped elongated slot; The short groove of 4-bar shaped; 5-gate slot; 6-overfall dam.
The specific embodiment
The utility model according to the loading characteristic of gate pier structure, utilize mechanics basic principle, reach the object of reinforcing gate pier by bar shaped fixture being set in gate pier side surface bar-shaped trough.In the utility model, additional bar shaped fixture, from heavy and light, changes former gate pier structure mode of appearance hardly; In bar-shaped trough, establishing bar shaped girth member can closely be connected with foundation structure, can improve largely the supporting capacity of gate pier structure; And the engineering time is short, at the bottom of construction space, equipment and environmental requirement, after gate pier structural strengthening, gate is moved without any impact.
Further illustrate the utility model below in conjunction with the drawings and the specific embodiments.
See Fig. 1, gate pier main body 1 side surface is pressed gate pier tensile region tensile stress direction and is dug the bar-shaped trough (3,4) that some length interleaved are arranged.Clean bar-shaped trough (3,4) surface and steel plate bar sticking veneer; Adopt cementing agent or logical set bolt, the steel plate bar mating with bar shaped elongated slot 3, short groove 4 length of bar shaped is individually fixed in bar shaped elongated slot 3 and the short groove 4 of bar shaped; Adopt cement mortar to the protection of steel plate bar appearance, gate pier can come into operation, and the cement mortar that is used for protecting can adopt polymer cement mortar, also can adopt conventional cement mortar.
Specific construction process of the present utility model is as follows:
Emergency Gate puts down dash, load on removal bracket 2; , dig and centered by bracket 2, be bar-shaped trough fan-shaped distribution, that length replaces by tensile stress direction at gate pier main body 1 side surface, clean bar shaped rooved face and steel plate bar sticking veneer; Coated with adhesive in bar-shaped trough, thick middle thin edge; Steel plate bar is affixed on to bar-shaped trough precalculated position, and suitably pressurization, so that cementing agent is just extruded as degree from steel plate bar side seam.After bonding adhesive solidifies completely, steel plate bar appearance is protected, recover gate pier structure mode of appearance, gate pier can come into operation.
The utility model gate pier structure, reasonable stress when work, the engineering time is short, at the bottom of construction space, equipment and environmental requirement, greatly reduces gate pier reinforcement cost, improves gate pier maintenance efficiency, has very strong practical value.Be applicable to the engineering fields such as water conservancy, water power, traffic and building.
