Description
Technical field
The utility model relates to a kind of baffle device for water of holes blocking under water, the semi-rigid baffle device for water of the interim shutoff of especially a kind of hole under water.
Background technology
At present in some reconstructions, the water conservancy of extending, hydroelectric project, particularly 70, water power, the hydraulic engineering of building the eighties, because design and construction technology level were lower at that time, construction quality is poor, long neglected and in disrepair, need interim shutoff dash when hole has been built in diversion, sluicing etc. under water keeped in repair, because hole inlet face poor flatness, the shutoff dash is a great problem.Adopt conventional steel gate structure complexity, operation is many, the engineering time is long, input cost is big, and rigidity gate sealing effect is relatively poor.In this case utility model a kind of semi-rigid baffle device for water of the interim shutoff of hole of having built under water is provided.
The utility model content
The utility model purpose is poor at the hole of the hole under water surface evenness of interim shutoff, the problem of shutoff sealing difficulty, proposed a kind of easy to operate, safe, quick, adapt to the baffle device for water that the border ability is strong, water plugging effect is good, be a kind of economical and practical " the interim shutoff baffle device for water of hole under water ", technical scheme is as described below:
The semi-rigid baffle device for water of the interim shutoff of a kind of hole under water, comprise horizontal girder, vertical secondary beam, steel facing, water sealing consolidation framework, water-stopping system, balance pipe valve and hanger, described steel facing is welded on the girder, the end of secondary beam and girder partly weld and form hinged or half hinged hinge, the water sealing consolidation framework is welded on the back side periphery of steel facing, water-stopping system is installed on the water sealing consolidation framework, middle and lower part at described device is symmetrically welded with the balance pipe valve along the device center of gravity line, and hanger is welded on the top of device center of gravity line.
Described balance pipe valve is provided with two.
Described hanger is welded on the secondary beam of device middle part setting.
Described water-stopping system comprises P type rubber sealing, dull and stereotyped shirt rim sealing and sealing pressing plate.
Described P type sealing and dull and stereotyped shirt rim sealing are fixed on the sealing fixed frame with bolt and sealing pressing plate.
Described secondary beam and girder are part welding, with bottom 5cm height and the Main Girder Welding of secondary beam, and at the top of girder and secondary beam junction the slit of weld reservation 3～5mm not.
The balance pipe that described balance pipe valve is used is steel pipe, is provided with valve at pipe end.
This device is simplified structure on the plate steel gate basis, has only designed girder, secondary beam, panel and water-stopping system; Secondary beam and girder adopt the part welding, in its top reserving gaps, secondary beam forms freely supported structure between girder, device is out of shape to adapt to the fluctuating of hole actinal surface along the distortion of secondary beam direction and distortion, with aperture periphery out-of-flatness face match, be convenient to water-stopping system and realize the purpose of sealing, satisfy the dash function of out-of-flatness face mouth.
The utility model fabrication and installation are simple, and are easy to operate, and it is strong to adapt to the border ability, and dash is effective, satisfy under water the hole interim shutoff needs of constructing, and are a kind of economical and practical devices.

The specific embodiment
The utility model at first as required interim shutoff build the size that hole design and real size are determined baffle device for water, the size of device girder 2 is bigger than size that need shutoff hole 11.Its structure design reference plane steel gate is theoretical to be calculated, and namely horizontal girder 2 should satisfy the needs of stressed strength and stiffness, by stressed equal, unequal-interval horizontal arrangement; 3 need of secondary beam satisfy stressed requirement of strength and do not consider rigidity requirement, and secondary beam 3 is in the vertical direction disposed at equal distance; Panel 1, hanger 10, suspension centre and weld seam etc. are carried out according to the hydraulic steel gate design specifications.
According to design size processing girder 2 and secondary beam 3, girder 2 and the welding of secondary beam 3 end parts, only with secondary beam 3 bottom 5cm height and girder 2 welding, and at the top of girder 2 and secondary beam 3 junctions not weld reserve the slit of 3～5mm, it is hinged or partly hinged that girder 2 and secondary beam 3 are formed, and secondary beam 3 becomes the freely supported structure beam 2 of girders.Panel 1 and girder 2 are welded together, and hanger 10 is welded on the secondary beam 3.At two balance pipe valves 9 of middle and lower part symmetric arrangement of device, balance pipe is steel pipe, at the pipe end mounted valve.Around the baffle device for water back side, sealing fixed frame 4 is set, with bolt 8 and sealing pressing plate 7 P type sealing 5 and dull and stereotyped shirt rim sealing 6 is fixed on the sealing fixed frame 4.
Hang baffle device for water hanger 10 with crane, baffle device for water is put into hole 11 import departments that need the dash shutoff after, the water in the emptying hole 11, this device bears water pressure, utilizes sealing to realize shutoff by girder 2, secondary beam 3 distortion.In order to prevent needing gate is temporarily fixed at 11 mouthfuls of wall tops of hole because SEA LEVEL VARIATION influences the stable of gate, crane breaks off relations and finishes the baffle device for water installation.
When hole construction finishes, baffle device for water is removed after finishing mission, hangs hanger 10 with crane, throw off the temporary fixed point of water-retaining structure after, the diver opens balance pipe valve 9 and discharges water behind the hydraulic pressure of this device of balance both sides, can hang out this baffle device for water, it is reusable.
Applications of in building under water the interim shutoff construction of hole, having succeeded of this device, these device fabrication and installation are simple, easy to operate, and it is strong to adapt to the border ability, and dash is effective, and the satisfied hole under water interim shutoff needs of constructing are a kind of economical and practical devices.
