Pump drainage tracheae 17 in member and closure unit interlayer is connected with air compressor.
Utility model works principle is summarized as follows：
1st, inverted U-shaped section 2 of weir body is located at the wall of upstream face highly more than the wall height of back side, upstream face wall,
Back side wall is arranged to arc transiting surface with roof junction, so as to form the streamline profile of wedge shape and end, is advantageous to subtract
Percussion of the weep to steel cofferdam；According to Hydrodynamics Theory, because current of the Shapes through object of object have directly
Influence is connect, the body form with respect to current determines its resistance coefficient, therefore uses streamlined steel cofferdam profile, reaches reduction
The form drag of steel cofferdam, improve steel cofferdam stability purpose.
2nd, sealing antiseepage：It is made up of L-shaped water seal 9, in-line water seal 10, water-swellable waterstop 11, using multinomial technology
Measure antiseepage, improve the reliability of steel cofferdam；The outer side elevation bottom of steel cofferdam（The base outer rim of the outer plate body 6 of wall）If one of L
Shape water seal 9, sealing, inner side are compressed by the water pressure of channel（The base inner edge of the outer plate body 6 of wall）If one of in-line water seal
10, the possibility leak at the position such as the honeycomb on blocking concrete surface, pitted skin, faulting of slab ends under steel cofferdam Gravitative Loads；Steel cofferdam is stood
Face bottom inside（The water-swellable waterstop 11 that the base outer rim of wall inner plate body 5 is set）Provided with water-swellable waterstop 11,
Sealing is carried out using its excellent elasticity, extensibility and expansion water-stop performance.Expansion rate can in water for water-swellable waterstop 11
Regulation, swelling volume keep the elasticity and extensibility of rubber, and expansion rate by water quality impact, does not have adaptive temperature scope wide, resistance to
Long function admirable, without harmful substance, without deep swollen precipitate, not polluted water the features such as；Often save and lead between inverted U-shaped weir body unit
Cross flange 4 to couple, twice O-ring seal is set among flange 4 to meet internode sealing requirement.
3rd, water tank 8 is set to form the sink-float device of steel cofferdam in the interlayer between adjacent I-shaped steel skeleton 7；When steel encloses
After the sliding in place of weir, steel cofferdam is increased to the water-filling of water tank 8 by centrifugal Self-priming sewage pump, solenoid directional control valve and stop valve 8.1
Counterweight, make steel cofferdam stable on the surface of canal slope liner plate 1；When removing steel cofferdam, pass through centrifugal Self-priming sewage pump, electromagnetic switch
Valve and stop valve 8.1 inflate the water in water tank 8 toward steel cofferdam internal drainage concora crush, while toward water tank 8 is interior, increase steel cofferdam
Buoyancy, sealing device is set to depart from the surface of canal slope liner plate 1.
4th, the vacuum cup 12 and vacuum chamber for being fixedly mounted with and putting and being arranged on inverted U-shaped weir body unit and block unit interlayer bottom are inhaled
13 and it is arranged on inverted U-shaped weir body unit and blocks the vacuum pipe 14 of the outer plate surface of wall inner plate body 5 of unit and form；Utilize
Water-ring vacuum pump forms negative pressure by vacuum cup 12, inhales steel cofferdam solid in the surface of canal slope liner plate 1, solution steel cofferdam steel
Fixation but the technical barrier of the existing liner plate of channel can not be destroyed.
5th, positioning apparatus is made up of sliding block 15 and bellows type air spring 16；Bellows type air spring 16 by pump drainage tracheae 17,
Regulating valve, displacement transducer and air accumulator and drying, dirt catcher are connected with air compressor, by bellows type air spring 16
Interior fills, deflates, and adjusts the height of bellows type air spring 16.
When steel cofferdam is installed, steel slide rail is laid in the Qu Po both sides for needing to repair first, is positioned.Steel cofferdam is hung vertical
Onto steel slide rail, after being slid in place by sliding block 15, controlling to adjust valve makes bellows type air spring 16 deflate, and reduces bellows air bullet
The height of spring 16, by centrifugal Self-priming sewage pump, solenoid directional control valve and stop valve 8.1, into water tank 8, water-filling increases counterweight, makes
Steel cofferdam sinks down into the upper surface of canal slope liner plate 1, after steel slide rail is fully entered in steel cofferdam cavity, starts water pump pump drainage steel cofferdam
Internal occluded water, then starting vavuum pump continuous air extraction makes vacuum cup 12 be adsorbed onto the upper surface of canal slope liner plate 1, completes steel and encloses
Weir is installed, and forms nonirrigated farmland working face under water, to repair the liner plate of breakage.When removing steel cofferdam, vavuum pump stops pumping,
By centrifugal Self-priming sewage pump, solenoid directional control valve and stop valve 8.1 by the water in water tank 8 toward discharging concora crush inside steel cofferdam,
Simultaneously toward the buoyancy of inflation increase steel cofferdam in water tank 8, sealing device is set to depart from the upper surface of canal slope liner plate 1；Control to adjust valve
Inflate bellows type air spring 16, steel slide rail departs from steel cofferdam, while slings steel cofferdam to land, completes steel cofferdam and removes.
6th, steel cofferdam passes sequentially through flange 4 by the inverted U-shaped weir body unit of more piece and sealing ring seals against each other connection, not only realizes
The live quick-assembling of steel cofferdam and dismounting, and also allow for the transport, maintenance and replacing of steel cofferdam；Inner plate body 5 and outer plate body 6
Between with standard I-steel 7 be keel, intensity is high, meets applying working condition intensity requirement, is easy to manufacture；It is provided with not between I-steel 7
Become rusty reinforced plastic water container 8, increases steel cofferdam integral rigidity, and satisfaction bears effect of water pressure.
