Description
Technical field
The utility model belongs to gas shield dam technical field, and in particular to a kind of gas shield dam sealing safeguard structure.
Background technique
The sealing part that is arranged between basic abutment wall in existing gas shield dam (is generally mounted on the end of the scuta on gas shield dam
The waterstop sealing part of the elastic wear-resistings material such as the rubber strip or air sac belt in portion support) it realizes and stops when scuta is lifted to form dam
Water prevents from revealing, but during water level lifting, the hydraulic pressure that sealing part is born is gradually increased, and leads to that sealing performance is not good,
It often reveals, more bad, sundries can cause to wear to waterstop in the water that high pressure water washes away, and cause, sealing part is close
Envelope sealing performance further declines and substantially reduces the service life of sealing part, increases maintenance cost.
Utility model content
The purpose of the utility model is to overcome existing structures to lead to the decline of sealing part hermetic seal performance and service life
The problem of shortening.
In order to achieve the above object, the utility model provides a kind of gas shield dam sealing safeguard structure, including scuta, it is mounted on shield
The sealing part of the lateral ends of plate and dam body abutment wall or middle pier on the outside of the lateral ends, the sealing part are in the cross
To between end and the dam body abutment wall or middle pier, during the scuta rises and to complete to be extruded after rising operation
Between the lateral ends and the dam body abutment wall or the facade of middle pier, thus have the function that hermetic seal, the dam body
One protection sealing boss of setting on the facade of abutment wall or middle pier, the protection sealing boss are arranged in after the scuta sufficiently rises
At the sideline of position, and the acting surface towards the scuta of the protection sealing boss has arc identical with the plate face of the scuta
Shape face, to realize that the acting surface and the plate face are closely connected identical, to promote water-stagnating effect；
The width of the acting surface is at least equal to the distance between the lateral ends of the scuta and described facade, to realize
Masking protection to sealing part.
The advantages of the utility model is as follows: structure is simple, easily fabricated and maintenance, especially effective protection sealing part and
The hermetic seal effect for enhancing scuta and dam body abutment wall or middle pier, extends the service life of total.
It elaborates with reference to the accompanying drawings and examples to the utility model.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of gas shield dam sealing safeguard structure.
Fig. 2 is the schematic diagram of elastic protection layer.
Fig. 3 is the schematic diagram that outer baffle is arranged on acting surface
Fig. 4 is the structural schematic diagram that outer baffle is engaged by double wedge with tooth cavity with Internal baffle.
Specific embodiment
It is a kind of gas shield dam sealing safeguard structure, the sealing including scuta 1, the lateral ends for being mounted on scuta 1 shown in Fig. 1
Part 2 and dam body abutment wall or middle pier 3 on the outside of the lateral ends, wherein sealing part 2 (generally has rubber, aeration zone etc. to have
The material of elasticity is constituted) between lateral ends and dam body abutment wall or middle pier 3, during scuta 1 rises and to complete
It is compressed between lateral ends and dam body abutment wall or the facade of middle pier 3 after rising operation, thus have the function that hermetic seal,
However this existing design has a defect that during scuta lifting, the raising of water level causes hydraulic pressure to rise, and
And scuta lifting during have leakage, and can be mingled with sundries pass through between sealing part 2 and dam body abutment wall or middle pier 3 or
It is mingled between inevitably resulting in sealing therebetween 2 abrasion, increases the gap between sealing part 2 and dam body abutment wall or middle pier 3, cause to stop
Water sealing property decline, will lead to over time gas shield dam performance decline, for this purpose, the present embodiment spy dam body abutment wall or in
One protection sealing boss 4 of setting on the facade of pier 3, the protection sealing boss 4 setting are completed to rise post-job position in scuta 4
At sideline, and the acting surface 5 of the protection sealing boss 4 towards scuta 1 has arcwall face identical with the plate face of scuta 1, with reality
Existing acting surface 5 is closely connected identical with plate face, to promote water-stagnating effect, also, the width of acting surface 5 is at least equal to the cross of scuta 1
To end and the distance between dam body abutment wall or the facade of middle pier 3, to realize that the masking to sealing part 2 is protected, as a result, by being somebody's turn to do
Sealing boss 4 is protected to bear punching press of the high pressure water level to sealing part 2, masking protection sealing part 2, moreover it is possible to promote the close of sealing part 2
Seal sealing effect.
In order to further enhance sealing performance of the sealing part 2 when bearing high pressure, the present embodiment spy is arranged on acting surface 5
Elastic protection layer 6 (has elasticity and the material of energy sealing) as known to rubber strip or rubber pneumatic bag etc., in the plate face of scuta 1
Conflict is deformed when on acting surface 5, to increase effective hermetic seal area, while realizing the protection to sealing part 2.
In order to ensure the stability and permanence of total, the transversal cross-section of elastic protection layer 6 provided in this embodiment
For T-type (being also possible to L-type, triangle, quadrangle or cylinder), as shown in Fig. 2, the elastic protection layer 6 is by 11 He of mounting surface
The sealing deformation face 12 being vertically set on the mounting surface 11 is constituted, and mounting surface 11 constitutes the transverse part of T-type, passes through rivet
Formed by integrally casting is fixed on acting surface 5 or after T-slot that the mounting surface is mounted on acting surface 5.
As shown in figure 3, an outer baffle 7 is arranged in the outer rim of acting surface 5, setting one can be handed over outer baffle 7 in the plate face of scuta 1
The Internal baffle 8 of mistake fitting is bonded by the outer baffle 7 with interlocking for Internal baffle 8 with contradicting when on acting surface 5 in plate face, real
Now the closing of sealing part 2 is isolated, to reduce the pressure-bearing of sealing part 2, to ensure the hermetic seal effect of the sealing part 2, together
When be effectively isolated damage of the sundries to sealing part 2.
Hydraulic pressure reaction force in order to ensure leakproofness, while when reducing closely connected present embodiments provides shown in Fig. 4 outer
The structure of baffle 7 and Internal baffle 8 is provided with multiple double wedges 9 evenly distributed along its length on the binding face of outer baffle 7；
The tooth cavity 10 of multiple receiving double wedges evenly distributed along its length is provided on the binding face of Internal baffle 8.
