Background technique
At present, in order to improve structural safety, ocean platform component and submerged pipeline in use, because fatigue, corrosion or some foeign element cause structural failure, ensure that it normally works, need to carry out maintenance and reinforcement work to them.Non-seif-citing rate technique of grouted clamp is a kind of modal underwater components restoring and fastening method, and expansion seif-citing rate technique of grouted clamp is also a kind of efficient of proposition recently and the restoring and fastening method that load-carrying properties are higher, and they generally adopt lag bolt type structure.But these technique of grouted clamp exist a lot of technological difficulties in installation process under water, wherein how to ensure that obtaining good sealing structure avoids grouting leakage to be exactly very important sport technique segment.
Model utility content
The utility model proposes a kind of lag bolt type technique of grouted clamp seal arrangement, which ensure that the grouting sealing of installing under water.
The utility model adopts following technological scheme to realize: a kind of technique of grouted clamp seal arrangement, comprise edge face sealing member and axial seal, wherein, edge face sealing member is separately positioned on the axial two ends of front band housing and lower catch hoop housing, edge face sealing member comprises sealing baffle, end-face seal ring and sunk screw, wherein sealing baffle comprises sealing baffle I and sealing baffle II, sunk screw comprises sunk screw I and sunk screw II, wherein sunk screw I is arranged on sealing baffle I, sunk screw II is arranged on sealing baffle II, end-face seal ring is arranged between sealing baffle I and sealing baffle II,
Before being mounted, there is primary clearance in end-face seal ring, this gap can be used to the axial compression amount controlling end-face seal ring between sunk screw I and the head of sunk screw II; Pad can be set on sunk screw I and/or sunk screw II, adjust the primary clearance between sunk screw I and sunk screw II head at any time;
Axial seal comprises axial sealing stripe, axial sealing stripe is arranged on clip shell flange plate interior edge face, housing two flanged plate interior edge face is slotted respectively to place sealing bar, axial sealing stripe takes the shape of the letter U, aliging with the end-face seal ring at clip housing two ends respectively in its two ends, thus forms the seal ring closed.
Described screw I and sunk screw II are arranged along the circumferencial direction interval of clip housing end face.
The beneficial effects of the utility model are:
By arranging edge face sealing member and axial seal, achieving the sealing of lag bolt type technique of grouted clamp housing, ensure that the grouting sealing of installing under water.
Accompanying drawing explanation

Fig. 2 is the partial enlarged drawing of edge face sealing member in Fig. 1;
Fig. 3 is the structural representation of the utility model axial seal;
Fig. 4 is the left view of the utility model axial seal.
In figure: 1 jacking bolt; 2 axial bolts stretchers; 3 jacking nuts; 4 jacking flanges; 5 sealing baffles I; 6 sunk screws I; 7 end-face seal rings; 8 sunk screws II; 9 sealing baffles II; 10 clip housings; 11 grouting rings; 12 axial sealing stripes; 13 shell flange plates; 14 impaired pipe fittings.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Described technique of grouted clamp seal arrangement comprises edge face sealing member and axial seal, and clip housing 10 comprises front band housing and lower catch hoop housing, and wherein edge face sealing member is separately positioned on the axial two ends of front band housing and lower catch hoop housing.Edge face sealing member comprises sealing baffle, end-face seal ring and sunk screw, wherein sealing baffle comprises sealing baffle I 5 and sealing baffle II 9, sunk screw comprises sunk screw I 6 and sunk screw II 8, wherein sunk screw I 6 is arranged on sealing baffle I 5, sunk screw II 8 is arranged on sealing baffle II 9, and end-face seal ring 7 is arranged between sealing baffle I 5 and sealing baffle II 9.The effect of sealing baffle is the position of restriction end-face seal ring 7, and is guided it to be radially out of shape when end-face seal ring compresses, thus the radial clearance between shutoff clip housing and reinforcing pipe fitting.
End-face seal ring 7 is before being mounted, primary clearance is there is between sunk screw I 6 and the head of sunk screw II 8, by arranging pad on sunk screw, can adjust the primary clearance between sunk screw I 6 and sunk screw II 8 head at any time, the head spacing of sunk screw I 6 and sunk screw II 8 controls end-face seal ring by the axial deflection compressed.In the present embodiment, the circumferencial direction along clip housing is provided with ten pairs of sunk screws.
Axial both sides along front band housing and lower catch hoop housing are equipped with clip shell flange plate 13, and clip shell flange plate 13 and clip housing are integral structure.Axial seal comprises axial sealing stripe 12, axial sealing stripe is arranged on clip shell flange plate 13 interior edge face, housing two flanged plate interior edge face is slotted respectively to place axial sealing stripe, axial sealing stripe 12 takes the shape of the letter U, aliging with the end-face seal ring at clip housing two ends respectively in its two ends, thus forms to grouting ring 11 seal ring closed in clip housing.
Under the effect of jacking bolt 1, axial bolts stretcher 2 drives jacking flange 4 to advance vertically, compression end-face seal ring 7, after the sunk screw I 6 being arranged on sealing baffle I 5 contacts with the sunk screw II 8 be arranged on sealing baffle II 9, end-face seal ring 7 has been axially compressed radial deformation, thus the radial clearance between shutoff clip housing and impaired pipe fitting 14; Axial sealing stripe 12 is set in clip shell flange plate 13 simultaneously, by tightening the bolt on flanged plate, the seal ring that axial sealing stripe 12 and end part seal circle 8 formation completing radial deformation are closed, thus realize the sealing of technique of grouted clamp, then grouting also plugging grouting import and export in clip housing, thus reach the object of repairing and reinforcement seabed underwater components.
