Description

Structure with enhanced stability used on the surface and its mounting method

The present invention is to prevent the leakage of soil by installing it in a place receiving external large water or large waves in order to prevent soil loss of rivers and coastal slopes, and more specifically, to improve structural fragility and interlocking, workability and It is about a structure with enhanced stability used for a slope that can secure stability and a mounting method thereof.

In general, slopes are installed on both sides of the river, and the slopes prevent flooding of the river to ensure the safety of residents adjacent to the river, as well as the banks formed in connection with the slope so that residents can lead a comfortable life. will help

On the slope of the river, a retaining wall is installed using concrete on the side in contact with the river, and a sidewalk is installed on the bank in contact with the slope.

However, most of the river slopes do not have countermeasures against loss in the event of a major flood, so it is our reality that the river slopes easily collapse during the rainy season, resulting in large-scale human accidents and property loss.

On the other hand, there was a problem that various filth thrown on the sidewalk flowed into the river together with rainwater, contaminating the river.

In addition, soil loss can be prevented by using a sofa block. The sofa block is installed at a place receiving a large wave of a breakwater or revetment for the purpose of dispersing or dissipating wave energy and reducing reflected waves. , mainly concrete blocks.

As a conventional sofa block, four horn-shaped tetrapods are most often used, and dolos and sealocks, which are modified tetrapods, are also widely used recently. In particular, the tetrapods are coated in a single layer or a multi-layer on the slope of the breakwater, or a plurality of them are densely formed to form one structure when constructing a coastal erosion structure such as a jammer. Breakwaters or river beds formed by stacking tetrapods disperse or dissipate wave energy by the gaps between adjacent tetrapods, the rugged shapes of the tetrapods themselves, and their intertwining.

The sofa block should have sufficient stability against wave force, have sufficient structural strength against external force or its own weight, be easy to lift and construct, and be able to obtain an appropriate porosity when stacked to attenuate wave energy. requirements are required.

On the other hand, there are two-layer covering types and random stacking methods for the method of mounting the sofa block. The two-layer covering types include upright covering types and sloped covering types. There is a one-sided covering type.

The random stack type is easy to implement and easy to install, so it has good constructability, but the appearance is not good because it is seen by the general public as a huge concrete structure piled up in a disorderly manner.

On the other hand, the two-layer covered type is advantageous in that the sofa blocks are arranged in an orderly manner and do not harm the surrounding aesthetics even when the sofa blocks, which are huge concrete structures, are arranged. There is a problem that the construction is difficult in that the direction (angle) must be adjusted.

In addition, regardless of the shape of the sofa block, it is very difficult to align the sofa block in the initial work because the conventional sofa block structure can only be stacked from the sea floor to the top surface along the slope. In other words, in order to align the sofa blocks on the seabed, many workers have to go down to the seabed and align and mount the sofa blocks in place. However, the risk of safety accidents on the seabed is also very high.

In the first step (S100), the shape of the reinforcing parts 140 and 150 and the leg parts 120 and 130 in the concrete block 100 composed of the body part 110, the leg parts 120 and 130, and the reinforcing parts 140 and 150 of the structure 10 This step is to calculate the length of Hereinafter, the shape of the reinforcing parts 140 and 150 and the calculation of the length of the leg parts 120 and 130 are the same as those described above for the structure 10. (Equations 1, 2 and 3 are used)

11 and 12 are tables showing stability coefficients (Kd) of structures with enhanced stability used for slopes according to an embodiment of the present invention compared to conventional products, and views of the above products. 13 is a table showing the structural analysis test results for the existing Sealock VIII and the structure (Seastone VIII) conducted by the Korea Institute of Industrial Technology.

As shown in FIGS. 11 to 13, structural weight and strength (stability) according to porosity act as major factors, and a structure with enhanced stability used for a slope according to an embodiment of the present invention and a mounting method thereof Referring first to FIGS. 11 and 12 , each of the leg parts 120 and 130 or the body part 110 is provided in a general cylindrical shape or, in particular, when it has a cross section of various polygonal shapes such as tetrahedron, hexahedron, octahedron, etc. Since the hydraulic stability, that is, the stability factor (Kd) can be increased, in particular, when the structure 10, which is a plurality of concrete blocks 100, is loaded, the surface contact area of one concrete block 100 and the adjacent concrete block 100 is It increases more in the case of a polygonal shape than in the case of a cylindrical shape, and the flow is prevented while the plurality of loaded concrete blocks 100 are engaged with each other.

Referring to FIG. 13, in the elements such as structural stability, hydraulic stability factor (Kd), interlock, economic feasibility, constructability, and maintainability, which are important elements in the structure 10, a large weight structure 10 is required recently. Therefore, structural stability is of paramount importance. For example, in the experimental results of the Korea Institute of Industrial Technology, the structural analysis results for the existing Sealock VIII and structure (10) (Seastone VIII) showed that the fracture strength was 1.9 to 2.3 times larger, especially because there were many angular parts, so the hydraulic stability factor (Kd) is also expected to be high and the interlock function is expected to be excellent due to the protrusion.

According to one embodiment of the present invention, it has sufficient stability against wave force when installed on the coast, etc., maintains structural strength against external force or its own weight, has effective curing and construction, and has a suitable porosity when laminated to attenuate wave energy. It is possible to obtain workability and stability when the structure 10 is mounted.

In addition, since the lifting protrusion 160 is installed in the form of a convex wedge on the lower part of the body 110, the extension of the shaft of the body 110, and the leg, in the case of a convex shape, the strength of the structure 10 is not damaged. It can be used, it is safe during construction, it can be constructed with excellent cohesiveness, and in the case of a heavy structure (10), the effect of preventing safety accidents and shortening the construction period due to mounting is great.

In addition, according to the present invention, the structural strength can be increased by 1.7 to 2.3 times or more compared to the existing structures, and the interlocking function can be improved.
