Abstract

The invention devises the hollow soil inside the hollow blocks, which are settled one by one, while the hollow blocks, which are quadrilateral blocks with four main walls, are settled one by one, and the sand is made of high quality sand in this space. By forming the foundation of a breakwater by establishing a certain depth of ground by replacing it, and then building a breakwater by fixing a structure such as caisson on the top of the hollow block based on this, it saves enormous cost and construction period. It is a devise for the breakwater structure that can be constructed while making a short breakwater.

Description

Breakwater structure built in cell block laying under the ground foundations.

The present invention is to devise a basic structure that firmly constructs a structure such as a breakwater on a soft ground or a seabed. In general, when constructing a superstructure such as a breakwater on a soft ground, According to the scale, the soft ground treatment must be performed first, and the soft ground treatment method includes a soft ground replacement method or a pile method for crushing the soft ground, and a ground compaction improvement method by grouting. In the present invention, the applicant of the present invention forms a foundation based on the construction method carried out in Patent No. 129092 'hollow block embedding replacement method' and constructs a structure such as a breakwater necessary for the upper surface of the foundation stage, Improvement proposal for the basic structure partially improved the substitution method ', with reference to the accompanying drawings Figure 1 First, the outline of the block buried substitution method will be described. The hollow block 1 having the upper and lower openings and the four main walls having a constant height is self-settled in a state in which it is kept horizontal on the soft ground and the hollow block (1). After excavating the soft soil (2) of the soft ground impregnated therein, another hollow block (1a) is laminated vertically on the upper surface of the first hollow block (1), and then settled, the inside of the first settled hollow block (1) The soft soil (2) is re-injected into the soil and the hollow soil (1) (1a) (1b) .... After the soil is excavated, the hollow soft soil (1) (1a) (1b) is replaced with the basic soft soil by putting high quality sand (3) into the empty space inside the hollow block foundation. A breakwater (B) body, which is a caisson (4) or the like, is placed on the upper surface of the stage (A), and then the inside is turned into a stone (5) or the like. The method of charging and fixing the cap concrete (6) at the top of the bar is the reason why the above-mentioned 'hollow block buried replacement method' was conceived. From the center of the location, it is necessary to excavate the soft ground of the inner and outer sea side to a great extent and depth, and then fill the empty space with a separate sandstone or high-quality sand. Previously, the invention was devised to solve such problems and to construct a foundation of a solid breakwater with a short construction period and low cost.

By applying the 'hollow block buried replacement method', which is the invention of the present invention as described above, the construction of breakwaters can be carried out to reduce the cost of construction and to build a breakwater with short air, but the invention is a hollow block than the width of the breakwater body. 1) (1a) (1b) ... The base end (A) width is larger than the caisson (4) width of the breakwater body to maintain the stability of the body. Due to this current, the problem of being scoured and lost after a long time cannot guarantee the stability of the body.

The present invention solves the problems arising from the above-described invention, while making the width of the foundation (A) the same as the width of the caisson (4) to further reduce the cost of construction of the breakwater, while constructing and maintaining a safe body without scouring. As devised to devise so as to be described in detail based on the accompanying drawings as follows.

The body of the breakwater according to the present invention is largely composed of a hollow block base end (A) and a caisson breakwater body (B) mounted on the upper surface of the hollow block base end (A), and thus become a breakwater body (B). The width of the upper hollow block 12 located below the dead stone foundation end 11 provided with the caisson 4 at a predetermined height on the upper surface of the soft ground 10 on the sea bottom is the same width as the width of the dead base foundation 11. As shown in FIG. 2, the upper hollow block 12 has vertical bulkheads 13 and 13a placed on the left and right sides of the same position as the width of the caisson 4, as shown in FIG. The upper hollow blocks 12 having male keys 14 and female keys 15 are positioned at the upper and lower middle portions of the vertical bulkheads 13 and 13a, respectively. The soft key is made of a hollow block 12a, 12b of a small length with a male key 14a protruding from each circumferential wall, the width of the caisson 4 of the means, and a female key 15a formed on the lower surface, respectively. This hollow block (12a) (12b) .. The hollow block base (A) is embedded in the van to replace the internal soft soil with high quality sand (13). A hollow block buried caisson breakwater foundation is constructed.

Since the structure of the hollow block buried caisson breakwater foundation stage is carried out according to the present invention configured as described above can be reduced by using a hollow block of a length smaller than the hollow block in the original invention method, The upper hollow block 12 stacked on the upper surface of the hollow block foundation is divided into vertical partitions 13 and 13a on the left and right sides of the inside of the hollow block, so that even if the foundation stage 11 is scoured and lost by current, the caisson ( 4) There is no dead stone oil inside the hollow block foundation (A) that is the same width, and it is effective to maintain a solid foundation for a long time.
