Description

Inclined type caisson breakwater

The present invention uses a unit caisson of a predetermined size as the main structure of the breakwater body, but the caisson structure of the trapezoidal shape in which the upper and lower sides of the caisson are sloping from the upper and lower sides of the caisson front and rear walls at a predetermined angle. The invention is about a unit caisson structure in a breakwater constructed by serially inclining a unit caisson characterized in that the breakwater is a facility structure for maintaining a quiet temperature in the harbor by blocking and blocking the waves that rush from the open sea. These breakwaters are determined by the size of the wave or the terrain conditions of the breakwater construction site.The construction of a sandstone breakwater in the depth of the breakwater construction site is enormous. To find a huge, natural stone To this end, the profound problem of environmental damage is inevitably raised.

Therefore, the caisson structure breakwater, which is made of caisson with a constant width, length and height and has a lower surface instead of a stone breakwater constructed with a huge amount of sandstone, is proposed, but in the early days of the caisson type breakwater, Since the unit caisson is made of concrete and has a large weight, large cranes should be mobilized to move and mount the large caisson to the construction site, but there are not many large cranes in Korea. The construction of the caisson breakwater is being gradually improved to reduce the size of the body and make it easy to construct.

As described above, the caisson type breakwater has been adopted more widely because it is very robust in terms of structural mechanics and economics, and it is advantageous in terms of work efficiency. Since the front wall, back wall, and left and right walls, which are structures, are all made of a rectangular box-shaped vertical wall, the upper part of the caisson that does not receive a large load from the upper part need not have the same size as the lower part. The same size is not only wasted unnecessary material for the manufacture of caissons, but also filled with a large amount of stone without filling the inside of the caisson, the present invention is a relatively small area of the upper end does not need a large resistance force and bear the full load of breakwater The lower end should be relatively large The left and right side walls are vertically lowered to form a trapezoidal caisson structure in which the front wall and the rear wall that are orthogonal to the left and right side walls are inclined surfaces having an inclination angle at a predetermined angle inward. Based on the above, it is as follows.

The structure of the unit caisson 10 of the inclined caisson breakwater 1 embodied in accordance with the present invention is provided with a basal stone 3 foundation end 4 having a predetermined height, length and width on the upper surface of the sea bottom 2. The front slope wall having a height similar to the height of the breakwater body and having an inclination angle at a predetermined angle inward at the front and rear ends of the bottom surface 11 having a constant width, length, and thickness of concrete in the center of the top surface of the sandstone foundation 4 12) and the rear inclined wall 13 are installed symmetrically, and the front inclined wall 12 and the rear inclined wall 13 are perpendicular to both ends of the front inclined wall 12, and the inclined sides of the front inclined wall 12 and the rear inclined wall 13 are inclined. Unit caisson 10 in the form of a vertically descending trapezoidal left side wall 14 and a right side wall 15 coinciding with the tip are serially arranged in the longitudinal direction in which the breakwater 1 is to be constructed. A female key 16 is formed in the center of the outer wall of the left wall 14 and the outer wall of the right wall 15 is formed vertically. The male key 17 is vertically protruded from the center, and a vertical partition 18 is placed at the center between the front inclined wall 12 and the rear inclined wall 13 of the unit caisson 10 internal space to partition the internal space. The interior space of the unit caisson 10 partitioned by the vertical bulkheads 18 is filled with a stone 19, while the left side wall 14 is perpendicular to the upper side of the front inclined wall 12 and the rear inclined wall 13, respectively. Semicircular circumferential walls 20, 20a, 20b between the partition walls 18 and between the right wall 15 and the vertical partition wall 18 to have the same inclination angle as the inclination angle of the front and rear inclination walls 12 and 13 ( 20c) and the semicircular circumferential walls 20, 20 (20a), 20b, 20c, 20. 20a) The outer surface protrudes a plurality of rows of vertical protrusions 22 and casts cap concrete 30 having a predetermined thickness on the upper surface of the unit caisson 10 having such a structure. The bottom surface 30 is partitioned by the top of the front inclined wall 12 and the top of the rear inclined wall 13 above the unit caisson 10 and the left side wall 14 and the right wall 15 and the vertical partition 18. By forming the step 31 so that the bottom surface of the cap concrete 30 is inserted into a predetermined depth in the upper space of the unit caisson 10, the unit caisson 10 and the cap concrete 30 can be maintained firmly. The vertical semicircular circumferential walls 34 and 35, which are perpendicular to the front surface 32 and the rear surface 33 of the cap concrete 30, respectively, protrude from the front surface 32 and the front surface 33, respectively. The body of the inclined caisson breakwater embodied in the present invention is constructed by laying a water hole 21a and protruding a plurality of vertical protrusions 22a on the front side vertical semicircular circumferential wall 34.

The sloping caisson breakwater configured in accordance with the present invention configured as described above is a sloping surface of the caisson front wall and the rear wall symmetrically inward to each other because the size of the caisson itself is less volume than the upright caisson manufacture itself Not only does it require less materials, but the amount of sandstone that is filled inside the caisson when building the breakwater is also less than that of the conventional caisson structure. The most rational breakwater structure that can minimize the material according to the minimum breakwater construction while maintaining the robustness of the breakwater body sufficiently, and the semicircular main walls 20 and 20a and the vertical semicircular main walls 34 provided on the front and back of the caisson. In addition to being couched by the seawater canister 21 installed in 35) By the number of vertical stone published 22 side-wave may also provide a breakwater having a multi-function to be a couch.
