The specific embodiment
Below in conjunction with accompanying drawing, further illustrate detailed content of the present invention and the specific embodiment thereof.
Referring to shown in Fig. 1 to Fig. 3, arch regulating dam of the present invention, comprises the lock chamber that is arch, and described lock chamber consists of gate pier 1 and gate floor 2, on described gate pier 1 and gate floor 2, hydraulic flap gate 3 is set, and multitower list rope face arch cable stayed bridge 4 is set on described gate pier 1; Described lock chamber adopts span centre parting, up-thin-low-thick, the large little tilting structure of tail of head that gate pier 1 adopts.
Shown in Figure 4, described hydraulic flap gate 3 comprises the gate flap 31 of upstream tilt 30 ° of 45 ° or inclined downstream, the middle and lower part of described gate flap 31 upstream faces 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 respectively hydraulic hoist, and the two ends of gate flap back timber are fixing hanger 39 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 respectively water seal arrangement 34, and inner chamber is provided with vibration-proof structure 35, and back side is provided with plugging plate 36.
Described hydraulic flap gate 3 is two cantilever freely-supporteds or the totally-enclosed streamline structure of continuous beam.
Referring to shown in Fig. 5 to Fig. 7, described multitower list rope face arch cable stayed bridge 4 comprises that plane is the girder 44 of 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-lines 47 by ground tackle and Sarasota top anchor, and form single rope face, 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, at case beam, is provided with triangle tuyere outward.
Described multitower list rope face 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 regulating dam tilts.
Described multitower list rope face arch cable stayed bridge 4 is considered the asymmetry of cable stayed bridge arched girder, 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 rope face, so except require girder wind resistance well, also its structure bending resistance torsional property of special requirement is excellent, adopt the streamlined Plate of Flat Steel Box Girder of unitary construction for this reason, at case beam, be provided with triangle tuyere outward, can improve wind resistance, and increase the landscape effect of girder.Sarasota is the main body that highlights 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 has embodied the imposing manner in poly-mind-set.Different from other pillar leaning tower, be to take bidirectional eccentric pressurized as main bending component.According to bridge deck width and requirement attractive in appearance, select fan-shaped single rope face.
Described hydraulic flap gate 3 is the two cantilever freely-supporteds 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 and formed waterfall.The pivot point of hydraulic flap gate approaches 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 by 1/3 left and right than lower shaft, thereby 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, thereby operation and maintenance is very convenient.Construction costs is low, is 2/3 left and right that lower shaft drives the investment of flap gate barrage.
Described lock chamber structure does not have cavity gate pier and the gallery of the lower shaft driving required tapping pressing system of flap gate (oil cylinder and independent pumping plant), and corresponding drainage system, and civilwork engineering quantity is relatively little.Primary load all concentrate on gate pier and gate floor on.Lock chamber structure adopts span centre parting, and 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 when 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, and for imbed parts of slab gate is installed, its surface has many places to need the second stage of concrete of building, complex process.During construction, require accurate positioning, smooth surface, the reliable anchoring of steel bar stress etc.
The present invention is applied in Liaoyuan City Dong Liao River view regulating dam integral body and is arch, the wide 96m of lock site place main stem, minute 5 holes, key construction by turnover panel regulating dam, lock after absorption basin and gabion apron revetment section form.Regulating dam divides 5 holes by equal length, and its bottom is hydraulic flap gate, and top is multitower list rope facial 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 modifications made for the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
