The specific embodiment

below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.

the utility model is constructed according to the construction method of the following pneumatic view lock of a kind of low height of weir lock, as Figure 1-3.The method adopts low overflow weir structure, to guarantee river course row's silt and flood discharge capacity; Along overflow weir 1 width, be provided with one group of pneumatic brake, between every fan pneumatic brake, by centre, only seal 5 connection (see figure 4)s, form whole gate dam; Whole group of pneumatic brake in whole gate dam adopts synchronous opening/closing mode, rises volt control river course upper pond level height to meet view requirement by gate dam.Described pneumatic brake comprises gate 3, gate and basic chain connection are realized by the hinge cover plate 4 wedge type heads in Bower Anchor bolt assembly 2 pressing clips castings tools 7 in gate base, it is retaining state that gate 3 be take pin joint when fulcrum upstream direction is rotated, and by adjusting the anglec of rotation, controls river course upper pond level to meet different landscape requirement; Gate 3 be take pin joint as fulcrum downstream rotation is maximum flood discharge state when lying on overflow weir 1, to meet the row in river course, becomes silted up and flood discharge capacity.Described gate 3 adopts peltate stainless steel component, and the upstream face of gate consists of the practical weir curve of conveyance capacity maximum the arcwall face of different curvature.Described gate be take the rotation that pin joint is fulcrum provides power by the air bag that is located at gate back, pin joint downstream; When air bag 6 inflation, by air bag 6, by gate 3 jack-up, make gate take pin joint and rotate as fulcrum to river course updrift side; When air bag deflation, gate 3 slowly rotates to river course downstream direction under Gravitative Loads, until gate 3 lies on overflow weir 1.The back side of gate is provided with the inhibition zone 8 being connected with overflow weir, limits stroke and the height of upstream gate by inhibition zone, and while guaranteeing airbag aeration, gate can upstream direction tipping.Described air bag 3 is cast tool 7 by folder and is fixed on Bower Anchor bolt assembly 2, by air supply system, air bag is inflated; Air bag is the two air bags of wedge shape that macromolecular material is made, to guarantee reliability and the stressed uniformity of air bag of gate action.

the structural representation of the pneumatic view brake structure of of the present utility model a kind of low height of weir lock building according to said method as Figure 1-3, this structure comprises the overflow weir 1 being located on river course cross section, upstream side along overflow weir 1 width is provided with one group of Bower Anchor bolt assembly 2, one group of Bower Anchor bolt assembly 2 is hinged with folder casting tool 7 and one group of gate 3 base through hinge cover plate 4, the wedge type head of hinge cover plate 4 embeds in the groove of folder casting tool 7, by Bower Anchor bolt assembly 2 pressing clip casting tools 7, realizes the hinged of gate; Between adjacent gate 3, through centre, only seal 5 connection (see figure 4)s; The door back end portion in the downstream of every fan brake door 3 pin joints is equipped with air bag 6.Air bag 6 is the two air bags of wedge shape; Air bag 6 is connected with Bower Anchor bolt assembly 2 through folder casting tool 7; , in described overflow weir 1, being provided with tracheae 10, tracheae 10 is connected with the air inlet port of air bag 6.The back side of described gate 3 is provided with inhibition zone 8, and inhibition zone 8 one end are connected with the top of gate back side, and inhibition zone 8 other ends are connected with the pre-buried draw piece 9 on overflow weir 1.Gate 3 be shaped as peltate stainless steel structure, the practical weir curve that the arcwall face that the upstream face of gate is different curvature forms.

Embodiment

it is example that this example be take Guiyang Nanming River red rock bridge to the Zhuanghe of leaf man section comprehensive management engineering.Because this section is positioned at urban district, thus to the having relatively high expectations of dam engineering, while not only requiring to meet flood, can drain off floodwaters timely and effectively, at ordinary times can also heading up, be convenient to build water landscape, for providing, citizen browse Condom.

for engineering demands, according to the width of this section, adopting four width is that the stainless steel gate 3 of 60 meters is as retaining box.In four shoe brake doors, have a tile height more lower slightly to be 8.18 meters, in the middle of causing, first to sluice, to reduce the impact force to river bank in the middle of being wherein located at.Remaining is highly 8.205 meters.On four shoe brake doors overflow weir 1 length direction being arranged in river course in one line.Between adjacent gate, by centre, only seal 5 connections, anti-sealing releases from the gap between two shoe brake doors.Four shoe brake doors adopt synchronous opening/closing mode, to simplify scheduling scheme.Gate adopts peltate structure, the upstream face of gate consists of the practical weir curve of conveyance capacity maximum the arc surface of different curvature, not only can effectively improve section flood carrying capacity and prevent that lock floor concrete is subject to current scour phenomenon, improving safety and the durability of engineering.And view requirement, novel and beautiful appearance have also been met in appearance.

aspect moulding, the bottom of gate is hinged with the one group of Bower Anchor bolt assembly 2 being embedded on overflow weir, and the whole gate dam that four shoe brake doors form resembles a large turnover panel, after turnover panel is dug, can meet the requirement of building water scenery in river course upstream inpoundment.When flood has come, whole gate dam can be fallen, whole gate dam is laid on overflow weir, guarantee flood carrying capacity, reduce flood plane line.Also can solve river channel sedimentation problem simultaneously.The upper upset power of gate adopts the principle of airbag aeration by gate jack-up, and the decline of gate adopts air bag deflation, utilizes gate deadweight slow decreasing.The switching process of gate is steady, and air bag adopts the two air bags of polymer inlet material, material environment friendly, and two air bags can guarantee the reliability of upset, after airbag aeration, resemble two large balls, simple for structure attractive in appearance.

in syndeton, when carrying out overflow weir construction, the pre-buried Bower Anchor bolt assembly 2 being connected with gate and the fixedly pre-buried draw piece 9 of inhibition zone 8, the bottom of gate 3 is fixed with hinge cover plate 4, hinge cover plate 4 is hinged with Bower Anchor bolt assembly 2 on the one hand, for supporting the weight of gate 3, hinge cover plate 4 also has the effect of water seal concurrently on the other hand, the erosion of anti-sealing to pin joint.In order to ensure, gate, in switching process, surpass peak and upstream topple over, at the back side of gate 3, be provided with inhibition zone 8, by inhibition zone, limit the stroke of upstream gate and highly, while guaranteeing in airbag aeration process gate standard-sized sheet, can not turn upside down.

gate of the present utility model can pass through automatic control technology, according to regimen, and combined dispatching between every grade of view sluice.Adopt Hydraulic Projects remote control technology, realize engineering immediately monitoring, data sharing and immediately process, guarantee the reliability of combined dispatching.

the utility model is by the enforcement to the Zhuanghe of leaf man section river course comprehensive management engineering to Guiyang Nanming River red rock bridge, and to this project construction complete after the observation of 1-2 practical operation situation, the feedback of operating condition, with both at home and abroad other has built the comparison of the view sluice moving, the utility model modern design, good looking appearance, sluice height and dash height are higher, multi-stage combination scheduling placement technique is advanced, have environmental protection, the feature of energy-conservation, low-carbon (LC).
