Abstract
The invention relates to an arch barrage which belongs to the field of urban landscape (water conservancy) engineering infrastructure. The arch barrage comprises an arch sluice chamber which is formed by a sluice pier and a sluice bottom plate, a hydraulic flip gate is arranged on the sluice pier and the sluice bottom plate, a multi-tower single cable face arch cable-stayed bridge is arranged on the sluice pier, mid-span parting is adopted in the sluice chamber, and an inclined type structure with a thin top, a thick bottom, a large head and a small tail is adopted in the sluice pier. The arch barrage has the advantages of being novel in integral combination and attractive in appearance. The arch barrage is completely different from a conventional barrage, the whole barrage is in a planer arc shape (a wrapping angle is about 80 degrees), and when water flows over the tops of a plurality of gates, arc falls can be formed, so that the arc barrage enables the falls to be attractive in appearance and impressive. It is totally different from watching the falls on the ground, a person can overlook the whole falls by standing on the cable-stayed bridge, and the visual effect is excellent. The arch barrage is applied to small, medium and large cities, thereby being high in practicality.

Detailed description of the invention
Detailed content of the present invention and detailed description of the invention thereof is further illustrated below in conjunction with accompanying drawing.
See shown in Fig. 1 to Fig. 3, arch barrage of the present invention, comprises the lock chamber in arch, and described lock chamber is made up of gate pier 1 and gate floor 2, and described gate pier 1 and gate floor 2 arrange oil pressured flap gate 3, described gate pier 1 is arranged multitower single cable plane arch cable stayed bridge 4; Described lock chamber adopts span centre parting, and gate pier 1 adopts up-thin-low-thick, that the large tail of head is little tilting structure.
Shown in Figure 4, described oil pressured flap gate 3 comprises the gate flap 31 of upstream tilt 45 ° or inclined downstream 30 °, the middle and lower part of described gate flap 31 upstream face or downstream face arranges hinges 32, described gate flap 31 is connected with a hinge bearing 33 by hinges 32, and described hinge bearing 33 is fixed on concrete buttress and gate floor; The left and right sides of described gate flap 31 arranges hydraulic hoist respectively, and hanger 39 is fixed at the two ends of gate flap back timber respectively, and each hanger is hinged with the cylinder piston rod 38 of corresponding hydraulic hoist respectively, and described cylinder piston rod 38 is arranged on hydraulic hoist hinged-support 37.
The left and right sides and the bottom of described gate flap 31 arrange water seal arrangement 34 respectively, and inner chamber is provided with vibration-proof structure 35, and back side is provided with plugging plate 36.
Described oil pressured flap gate 3 is two cantilever freely-supported or the totally-enclosed streamline structure of continuous beam.
See shown in Fig. 5 to Fig. 7, described multitower single cable plane arch cable stayed bridge 4 comprises the girder 44 that plane is the steel work of arch, described girder 44 is bearing on limit Sarasota 41, middle Sarasota 42 and abutment pier 49 by spherical fixed bearing 45 and the spherical bearing 46 that vertically moves, limit Sarasota 41 and middle Sarasota 42 are cemented on the gate pier 1 of regulating dam by crab-bolt, the span centre of girder 44 arranges several drag-line 47 by ground tackle and Sarasota top anchor, and form single cable plane, the end of girder 44 is provided with stretching device 48, and bridge floor is provided with light guardrail 43.
Described girder 44 adopts the streamlined Plate of Flat Steel Box Girder of unitary construction, is provided with triangle tuyere outside case beam.
Described multitower single cable plane arch cable stayed bridge 4 and lock chamber concentric, its Sarasota is along water (flow) direction, unified towards a point---and the center of circle of arch barrage tilts.
The asymmetry of cable stayed bridge arched girder considered by described multitower single cable plane arch cable stayed bridge 4, structural system adopts half relatively safe float system, be characterized in Pylon pier consolidation, girder arranges vertical support on Sarasota, becomes and has the flexibly mounted continuous beam of multiple spot.The feature of cable-stayed bridge main-beam is planar unsymmetrical (arc) and single cable plane, so except requiring that girder wind resistance well, also specially require its structure bending resistance torsional property excellent, adopt the streamlined Plate of Flat Steel Box Girder of unitary construction for this reason, triangle tuyere is provided with outside case beam, can wind resistance be improved, and increase the landscape effect of girder.Sarasota is the main body highlighting cable stayed bridge view, integrated beauty learning aid for cable stayed bridge has vital impact, and the Sarasota of cable stayed bridge of the present invention is pillar steel leaning tower, and all leaning towers are along water (flow) direction, unified towards a point---the center of circle of arch lock tilts, and embodies poly-heart imposing manner upwards.Different from other pillar leaning tower, be the bending component based on biaxial eccentric load.According to bridge deck width and aesthetic, select fan-shaped single cable plane.
Described oil pressured flap gate 3 is the two cantilever freely-supported of totally-enclosed streamlined or beam structure, and metal material can be fully used, and gate flap deadweight is lighter.When gate in off position time door pushed up water formed waterfall.The pivot point of oil pressured flap gate is close to gate flap point of resultant force, and gate flywheel moment is very little, and the rotation distance of gate suspension centre drives flap gate to reduce about 1/3 than lower shaft, and thus hydraulic hoist capacity and stroke can be less.Generally can establish a shared hydraulic power unit, complete the centralized Control to porous gate number cover hydraulic hoist.Except being provided with dismountable hydraulic hoist and oil pipe line protective equipment thereof, other all devices is arranged in daylight, and thus operation and maintenance is very convenient.Construction costs is low, is that lower shaft drives about 2/3 of flap gate barrage investment.
Described lock chamber structure does not have lower shaft to drive cavity gate pier and the gallery of tapping pressing system (oil cylinder and independent pumping plant) required for flap gate, and corresponding drainage system, and civilwork engineering quantity is relatively little.Primary load all concentrates on gate pier with on gate floor.Lock chamber structure adopts span centre parting, and namely every hole gate pier and both sides gate floor form overall structure; The middle pier of hole lock adopts the tilting space structures of " the large tail of up-thin-low-thick, head is little ", and while bearing the load that stayed bridge pylon cable transmits, gate pier has good flow condition, does not block water, cavitation is little; After lock, absorption basin hoop is arranged, is beneficial to energy dissipating, reduces cost.Gate pier is not only three-D space structure, for installing imbed parts of slab gate, and the concrete that its surface has many places to need the second phase to build, complex process.Accurate positioning is required, smooth surface, the reliable anchoring of steel bar stress etc. during construction.
The present invention is applied in Liaoyuan City Dong Liao River view regulating dam entirety in arch, and the wide 96m of lock site place main stem, point 5 holes, key construction is made up of absorption basin after turnover panel regulating dam, lock and gabion apron revetment section.Regulating dam divides 5 holes by equal length, is oil pressured flap gate bottom it, and top is multitower single cable plane plane arch cable stayed bridge, and this bridge is service work bridge, is again sightseeing bridge.
The foregoing is only preferred embodiment of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All any amendments made for the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
