Description

Foundation treatment structure of composite breakwater

The present invention is to devise a hybrid breakwater in the state of reinforcing the seabed soft ground when it is necessary to build a breakwater on the seabed soft ground. For example, hybrid breakwater refers to a breakwater that has a sofa function by covering it with tetrapod or the like on the external seaside slope of the sand breakwater. Therefore, when it is necessary to construct a hybrid breakwater on a soft undersea, As the slope of the inclined surface of the internal and external seas is constructed to be a gradient of 1: 1.5, as shown in FIG. 1 of the accompanying drawings, the soft ground to the hard ground below the soft ground by grouting, etc. Reinforcement should be done.

As described above, hybrid breakwaters are generally the most widely adopted breakwater structure.Because of their structural characteristics, the hybrid breakwaters have a relatively large base width, so that the soft ground area for reinforcement becomes wider in the soft ground area that needs soft ground treatment. As a result of excessive investment in soft ground treatment, and the demand for natural stone is also huge, it is necessary to obtain a large amount of stone. Therefore, there is also a problem of natural damage for the procurement of this stone.

Therefore, there is a need for a reliable foundation structure type with sufficient rigidity while being inclined as much as possible and reducing the base bottom width range as much as possible.

The present invention is a design devised for the treatment structure of the base portion of the hybrid breakwater that can secure the robustness while minimizing the range of soft ground improvement as described above, as described above based on the accompanying drawings.

First, the structure of the hybrid breakwater 1 constructed on the conventional soft ground will be described schematically. The soft ground 3 located under a certain depth of water 2 and the hard ground 4 positioned below the soft ground 3 will be described. The grout (5) is vertically grouted in multiple places at equal intervals between the widths of the mixed breakwaters (1) to improve the soft ground, and then the slope of 1: 1.5 on the upper surface of the soft ground (3) above these grouts (5). A blast-furnace (6) breakwater (1) was constructed, and the inner and outer sea side inclined surfaces (7) and (7a) were covered with coated stones (8) and (8a), and then the top surface of the covered stone (8a) on the inclined sea (7a). A hybrid blocker 1 is formed by statically or vigorously disposing a sofa block such as tetrapod 9 or the like, and a solid breakwater 1 while significantly narrowing the width between the inner and outer sea side slopes 7 and 7a. Attached to the treatment structure of the foundation of the hybrid breakwater (1) constituted by the present invention for constituting the body of If the surface is also described on the basis of the two follows.

The structure of the hybrid breakwater (1) implemented according to the present invention has a plurality of hollow blocks (10) on the outer and inner sea sides of the upper surface of the soft ground (3) so as to have a width narrower than that of the conventional breakwater (1). The hollow blocks 10, which are vertically stacked in multiple stages and fill the sandstone 11 in the inner spaces of the hollow blocks 10, are formed at predetermined heights on the inner and outer sea sides, and the inner and outer boundary walls 12 of the breakwater. (12a) and fill the sandstone (13) in the space between the boundary walls (12) and (12a) so that it becomes a hybrid breakwater (1) body, and cures the cap concrete (20) on the body surface. The mounting jaw plates 14 and 14a are installed inside the hollow block 10 at the top of the walls 12 and 12a, and then the slanted surface 15 between the locking jaw plates 14 and 14a and the cap concrete 20 Coated stones 16 and 16a are coated on 15a) and a sofa block such as tetrapod 17 or the like is placed on the upper surface of coated stone 16 on the inclined surface 15 on the outer sea side. The grout (5) is grouted in the soft ground between the lower soft ground (3) and the hard ground (4) to reduce the soft ground, and the actual construction is first performed by the soft ground (3) and the hard ground (4). The grout 5 is grouted in this soft ground width area by first setting a constant width between the grounds and the soft ground is improved. Then, the above-mentioned hybrid breakwater 1 is applied to the upper surface of the improved ground.

As described above, the grout is formed in the soft ground with a constant width, and the soft ground is improved. Then, the inner and outer boundary walls 12 (12a), which are hollow blocks 10 with a narrow width, are provided on the grout. By filling the sandstone in the space between the inner and outer boundary walls 12 (12a) to build the body of the hybrid breakwater (1), the width of the hybrid breakwater (1) is greatly reduced to build a breakwater. The inside of the inner and outer boundary walls 12 and 12a is filled with the sandstone 11, which acts as a resistor, so that it is possible to minimize the amount of sandstone, construction cost and construction time required while constructing a solid body. It is possible to provide a very economic hybrid breakwater.
