Description

Movable-type Cap-concrete Structure

The present invention relates to a movable upper-sided concrete structure, and specifically, to a movable upper-side concrete structure that is installed on a breakwater or a shore and blocks the over-wave by automatically rising the moving part due to the increase in air pressure due to the number of waves.

Breakwater is roughly classified into a caisson type (stand-up type) breakwater, a quarry-type breakwater, and a hybrid breakwater. When a breakwater is constructed in a sea area where high wave height is expected, when the wave breaks through the breakwater, the ship is anchored in the inland sea, pier facilities Since the back is concerned about damage, the structure of the lettuce concrete is known to increase the height of the lettuce concrete so as to prevent the wave from overtaking the breakwater while blocking the overwave.

1 is a cross-sectional view of a breakwater of a hybrid material made of conventional lettuce concrete.

As shown, the upper edge of the upper side of the concrete (10) protruding railing (11) protruding to the offshore side and the outer wall surface of the upper side of the concrete (10) of the lower side of the protruding rail (11) (12) ( It is formed of 13), even if a high wave of blue invades, it hits the uneven surface 12, 13 of the outer wall surface of the upper concrete 10 and weakens and sofas the blue wave power by diffraction, reflection, and the like.

In particular, by blocking the blue wave by the protruding railing 11 of the lettuce concrete 10, the inner port of the pier can always maintain a constant temperature, and the height of the lettuce concrete 10 can be determined according to the maximum crest value of the year depending on the region. Since it does not increase the whole breakwater, the construction cost associated with the construction of a breakwater can be reduced, and since the upper concrete is a heavy material as it is a bulk, the breakwater does not generate displacement due to the wave power even if it is fixed on the top of the breakwater by its own weight. The structure is known.

Reference numeral 4, which is not described, is a coated stone, and reference numeral 5 is tetrapod.

However, in the structure of the conventional breakwater as described above, since the height is always constant without a separate means for adjusting the height of the upper concrete 10 above the surface of the seawater, when the initial construction is excessively elevated, the height of the upper concrete 10 is viewed Not only is the castle degraded, but there is a problem that the construction cost is high.

In addition, in the case of lowering the upper concrete 10 on the surface of the sea water during the initial construction, there is a problem that the wave height is increased due to a storm or a typhoon, so that it does not prevent the phenomenon of passing the breakwater and thus does not properly function as a breakwater.

FIG. 6 is a partially enlarged view of the upper concrete, showing another embodiment of the movable part in the open state of FIG. 5

As illustrated, in the present embodiment, the movable member 162 may be rotatably installed on one side of the first protrusion 1515 by one end of the third movable plate 1625 in the form of a cantilever beam by a hinge 1623. In addition, the other end of the third movable plate 1625 is characterized by being connected to the other end of the upper surface of the first protrusion 1515 by a connection cable, and the rest of the configuration is the same as the above-described embodiment.

Looking at the working relationship of the above configuration,

When a wave occurs due to a storm or a typhoon, the sea water fills up inside the tank 130 by the wave number, and air is trapped in the lower space of the support portion located in the tank 130. When seawater continues to fill up in the water tank, air in the lower space of the support portion moves to the elastic member through the exhaust hole. Accordingly, the elastic member can be expanded by receiving an external force (eg, pneumatic pressure). Accordingly, an expansion space may be formed between the elastic member and the exhaust hole. The expanded elastic member is pushed by pushing the movable member, and the movable member is caused to stand by rotating the movable member upwardly around the hinge due to the expansion force of the elastic member that exceeds the elastic force of the torsion spring 1624 of the hinge, thereby standing. It can be blocked. At this time, the connecting member shown in FIG. 5 can prevent the movable member from falling in the opposite direction.

When the water level in the open sea becomes low due to a storm or typhoon passing through, the seawater inside the water tank 130 is discharged to the drain, and thus, the air in the expansion space moves to the lower space of the support body part through the exhaust hole. Accordingly, the elastic member contracts, and the movable plate returns to its original state by the elastic force of the torsion spring 1624 of the hinge.

When the material of the elastic member is described below, since the elastic member comes into contact with salt water, such as sea water, on the island or the beach, it is susceptible to salt damage due to salt water. As a cause of salt damage, salt that is directly contacted by the waves, or is scattered in the air due to the wind wave, flies to the elastic member and adheres to the surface of the elastic member, or floats in the air during rain. ) Salt is dropped with rain and attached to the elastic member. When the elastic member is corroded by seawater, the effect of elastic deformation may be lowered. In this embodiment, the rubber material of the elastic member It discloses an invention that minimizes corrosion of seawater by specifying.

The rubber material of the elastic member is 10 to 20 parts by weight of reinforcing resin, 1 to 5 parts by weight of zinc oxide, 10 to 20 parts by weight of fatty acid amide compound as water repellent, 25 to 30 parts by weight of carbon black, It consists of a rubber composition containing 0.01 to 3 parts by weight of cobalt and 2 to 4 parts by weight of quinone-imine-based antioxidant.

The rubber composition as described above has improved heat aging resistance, can prevent the deterioration of rubber, has a reinforcing effect, has salinity, such as an island or a beach, and has excellent durability even when used for a long time in a hot and humid area. Have it.

In this way, by adopting a rubber composition capable of minimizing corrosion and aging in a region with severe external conditions, as a rubber material of the elastic member, it has a function of continuously maintaining the elastic restoring force of the elastic member and the sealing force closing the exhaust hole. .

The above-mentioned breakwater or movable lettuce concrete installed on the shore can be easily folded and secured for viewing, and when standing over, it can automatically stand up and block the wave and the rubber tube is corroded by seawater. It has the effect of minimizing being.
