Abstract
The utility model relates to a water carriage project, in particular to a ship lock expansion joint. In order to solve the problem of the repair for the damage of the ship lock expansion joint, the ship lock expansion includes a water stop mounting plate (2) and the expansion joint (1). The ship lock expansion joint is characterized in that a pressing plate (4) is arranged on the expansion joint. The pressing plate presses the expansion joint (1) into the water stop mounting plate (2). The shape of the expansion joint (1) is matched to the shape of the water stop pressing plate (2). The expansion joint (1) is fixed with the pressing plate through a bolt. The expansion joint (1) is made of the rubber. The expansion joint type of the ship lock expansion joint solves the problem that the damage of the original expansion joint cannot be repaired. The expansion joint type of the ship lock expansion joint has the advantages of being convenient and rapid in installation and disassembly.
Description
Technical field
The utility model relates to marine traffic engineering, particularly the shrinkage joint of ship lock.
Background technology
Ship lock is a kind of navigation structure that overcomes the concentrated water-head of building dam (or natural) formation on the river, it is comprised of upper tail-bay (arranging the gate and valve system), lock chamber, approach channel etc., fill with sluicing by valve system, make the lock chamber fluctuation in stage, finish the boats and ships lockage.
Lock chamber length is generally 100 meters and does not wait to 260 meters, large-scale ship lock even longer, the lock chamber materials for wall is generally concrete, the piece stone material is also arranged in early days, build concrete in mass problem of Cracking in period in order to solve ship lock, and adapt to and to build up rear concrete expanding with heat and contract with cold and the differential settlement of ground, general per about 20 meters of lock chamber arranges together flexible (sealing) seam.
Build the lock initial stage, copper seal in flexible-settlement joint and asphalt filler are under soil matrix differential settlement and the concrete dual effect of stress that expands with heat and contract with cold, local failure occurs, behind ship lock works settlement stability, sedimentation-expanded joint structure mainly is subjected to the concrete stress repetition effect of expanding with heat and contract with cold, cause the fatigue damage of copper seal, add the long-term use along with the ship lock structure, asphalt filler aging, the lock wall suffers the many reasons such as bump of boats and ships, so that the ship lock shrinkage joint is destroyed, the filling that lock chamber is repeated multiple times, sluice and infiltrate by the shrinkage joint of damaging, ooze out metope, thereby empty sand filter blanket behind the wall, form the hole, when causing lock chamber to rise, inwardly pour water, when lock chamber sluices, the sight of outside jetting, can make behind the wall part sinking of banketing when serious, jeopardize the safe operation of ship lock.
The utility model content
Technical problem to be solved:
The reparation problem is damaged at the ship lock shrinkage joint.
Technical scheme:
In order to overcome the above problems, the utility model provides a kind of reliable, reasonable, safe scheme, a kind of ship lock shrinkage joint, comprise sealing installing plate 2 and shrinkage joint 1, it is characterized in that: be provided with pressing plate 4 shrinkage joint 1 is pressed into sealing installing plate 2, stretch and inside contract seam 1 shape and the shape of sealing installing plate 2 matches, shrinkage joint 1 and pressing plate 4 are fixing by bolt 3.
Sealing installing plate 2 materials are steel plate, and shrinkage joint 1 material is rubber.
Shrinkage joint 1 is Ω shape.
Pressing plate 4 is detachable.
Beneficial effect:
This shrinkage joint pattern has solved the problem that can't repair after former shrinkage joint is damaged, and installation, convenient disassembly are quick.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the structure at ship lock of the present utility model shrinkage joint is: be provided with pressing plate 4 shrinkage joint 1 is pressed into sealing installing plate 2, stretch and inside contract seam 1 shape and the shape of sealing installing plate 2 matches, shrinkage joint 1 and pressing plate 4 are fixing by bolt 3, wherein shrinkage joint 1 is rubber, and sealing installing plate 2 is steel plate.The shrinkage joint of this type is comprised of installing plate and water stop rubber, and it can compress rubber the sealing effect, can lean on again the elasticity of rubber, satisfies certain the stretching in shrinkage joint.Because through use for many years, this moment, the sedimentation of lock chamber structure was stable, and the telescopic action of concrete heat expansion shrinkage is substantially only played at sedimentation-shrinkage joint, and the elasticity of rubber itself can satisfy.
Shrinkage joint 1 is Ω shape, shrinkage joint 1 easier being installed in the installing plate 2 of this kind shape.
Pressing plate 4 is detachable simultaneously, after ageing of rubber, damage, as long as after removing the pressing plate of front, just can change water stop rubber, former shrinkage joint can not occur and damage the phenomena that causes because of ageing of asphalt, sealing.
Although the utility model with preferred embodiment openly as above; but they are not to limit the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can make various changes or retouch from working as, what therefore protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.
Claims (4)
1. ship lock shrinkage joint, comprise sealing installing plate (2) and shrinkage joint (1), it is characterized in that: be provided with pressing plate (4) shrinkage joint (1) is pressed into sealing installing plate (2), stretch the shape that inside contracts seam (1) and the shape of sealing installing plate (2) and match, shrinkage joint (1) and pressing plate (4) are fixing by bolt (3).
2. ship lock as claimed in claim 1 shrinkage joint, it is characterized in that: pressing plate (4) is detachable.
3. ship lock as claimed in claim 1 shrinkage joint, it is characterized in that: sealing installing plate (2) material is steel plate, shrinkage joint (1) material is rubber.
4. such as the described ship lock of the arbitrary claim of claim 1-3 shrinkage joint, it is characterized in that: shrinkage joint (1) is Ω shape.
