3 is a detailed view showing a tie bar installed between the first wall and the second wall in the underwater condition according to the present invention.
FIGS. 4 to 10 are perspective views illustrating steps in a submerged construction method according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in order to obscure or obscure the technical idea of the present invention due to the detailed description of the known structure in describing the present invention, the description of the structure of the above known structure will be omitted.

In the description of the embodiment of the present invention, the term 'front' or 'front' as a direction indicates a direction in which an underwater structure as a main structure is installed, a direction of a work area formed by the submerged structure 100 of the present invention Quot; rear " or " rear " means the outward direction of the work section.

FIG. 2 is a perspective view showing the structure of a submerged membrane 100 according to an embodiment of the present invention.

As shown in FIG. 2, the structure of the water hammer 100 according to the present invention can be applied most effectively to a hypothetical case where water is installed in a waterless soil without soil gravel soil, Sheet files 113 and 123 for preventing the water from flowing into the work section while supporting the side pressure by the gravel 150 filled in the water tank 100 according to the construction of the underwater obstacle 100, And horizontal supporting beams 112 and 122 for uniformly distributing the horizontal loads acting on the H files 111 and 121 to the H files 111 and 121. The horizontal supporting beams 112 and 122 are formed on the basis of the positions of the walls 110 and 120 constituting the underwater hypothetical body 100 A welt 115 is additionally provided.

The water submerged structure 100 of the present invention includes a first wall 110 installed on the outer side of a work section where a concrete structure is installed and a second wall 110 installed apart from the first wall 110 to form a filling space C Two walls 120 and a gravel 150 filled in the filling space C. [

The first wall 110 is constituted by a holding H file 111, a horizontal support beam 112, a wale band 115, and a sheet file 113 as described above.

The holding H file 111 is formed so as to be deeply inserted into the rock bed 160 of the underwater floor so that not only the vertical load of the first wall 110 but also the earth pressure by the soil 150 inside the underwater hypothetical 100, And supports various horizontal loads from the outside of the apparatus 100.

The horizontal support beams 112 are provided horizontally long in contact with the rear surface of the H file 111, and a plurality of horizontal support beams 112 are arranged at predetermined intervals in the vertical direction.

Since the horizontal support beam 112 is transmitted to the H file 111 only with respect to the horizontal load transmitted by the sheet file 113, It is not necessarily required to be fixed integrally with the H file 111 as long as the projected correct position can be maintained. It is possible to fix the position of the horizontal support beam 112 by welding it to the H file 111 so as to fix the position of the horizontal support beam 112 by welding or simply mounting the horizontal support beam 112 without integrating the horizontal support beam 112 into the H file 111, So that the position of the light source can be fixed. This will be described in detail with respect to the installation of the horizontal support beams 112 during the construction process described later.

The sheet file 113 is installed in contact with the rear surface of the horizontal support beam 112.

The sheet file 113 is formed by bending a watertight steel plate and penetrates at least the existing soil layer 151 so that the lower end of the sheet file 113 is deeply inserted into the rock bed 160 of the underwater floor, Together with the file 123, functions as a form for filling the gravels 150, and a waterproof function, which is a main role of the underwater hypothetical project 100, is performed.

The lower end of the sheet file 113 may be further provided with a water wall 141 configured to be embedded in the lower end of the H file 111 together.

The horizontal load acting on the sheet file 113 via the horizontal support beams 112 is transmitted to the braces 115 through the wales 115.

That is, the wrist strap 115 is provided horizontally in contact with the front surface of the H-file 111, so that the wrist strap 115 can be supported by the brace 115, and the wrist strap 115 acts on a plurality of H files 111 So that the first wall 110 can maintain structural stability by evenly distributing the horizontal load and transmitting it to the braces 115.

The second wall 120 installed outside the underwater obstacle 100 also includes a support H file 121, a horizontal support beam 122 and a sheet file 123. However, unlike the first wall 110, The wrist strap 115 is not installed.

That is, the second wall 120 includes a support H file 121 extending to the rock 160 of the underwater floor, a horizontal support beam 122 installed in contact with the front surface of the H file 121, And a sheet file 123 provided in contact with the front surface of the support beam 122.

Since the configuration and installation of the H file 121, the horizontal support beam 122 and the sheet file 123 are not different from the first wall 110, I'll give it a try. Further, the water wall 142 corresponding to the first wall 110 is installed on the rear surface of the lower end of the sheet file 123.

3 is a detailed view showing an embodiment of the upper structure of the hypothetical underwater according to the present invention.

As shown in FIG. 3, the uppermost ends of the first wall 110 and the second wall 120 are formed by a side pressure of the gravel 150 filled in the filling space C between the walls 110 and 120 A tie bar 130 may be further provided.

The upper surface of the H-file 111 of the first wall 110 and the upper surface of the rear surface of the H-file 121 of the second wall 120 are fixed to a fixing table 114, < RTI ID = 0.0 > 124)

At this time, in the first wall 110, the wristband 115 located at the uppermost one of the wands 115 installed on the front surface of the H-file 111 serves as a function of a fixing table 115 for installing the tie bar 130 You may.

In addition, the fixing brackets 131 and 124 for fixing both ends of the tie bar 130 are provided on the fixing bars 114 and 124, respectively.

The construction of the underwater hypothecation 100 is completed by filling the filler space C between the first wall body 110 and the second wall body 120 with the gravel 150.

As described above with respect to the structure of the underwater hypothecic membrane 100 of the present invention, the underwater hypothecic membrane 100 is constructed by simultaneously or sequentially forming the first wall body 110 and the second wall body 120, And the gravel 150 is filled in the filling space C so as to be constructed.

The horizontal support beams 112 and 122 are provided in contact with the rear surface of the H file 111 on the first wall 110 and the H file 121 on the second wall 120 side.

The horizontal support beams 112 and 122 may be formed by welding the horizontal support beams 112 and 122 to the H files 111 and 121 as shown in FIG. 5A. However, Since the beams 112 and 122 can be installed so as to maintain the vertical positions, they may be installed in a manner of hanging from the top without welding the H files 111 and 121 to the H files 111 and 121.

5 (b) shows the horizontal support beams 112 and 122 in the H files 111 and 121 (FIG. 5) by using the latter hanging method, unlike the former embodiment in which the horizontal support beams 112 and 122 are fixed to the H files 111 and 121 by welding. As shown in Fig.

To this end, the h files 111 and 121 may further include a hanger bracket 117 protruding in the lateral direction. The hanger bracket 117 may be provided with hooks for fixing the other end of the suspension cable 119, 118 are further provided on the horizontal support beams 112, 122.

The installation of the horizontal support beams 112 and 122 by the hanging method prevents the welding process from occurring in the water, thereby improving the workability and reducing the labor costs. Further, It is possible to recover the support beams 112 and 122 as they are, without damaging them, and to exhibit economical effects such as significantly reducing the construction cost due to repeated use of the material.

c) The sheet files 113,  Installing step (Fig. 6);

When the installation of the horizontal support beams 112 and 122 to the H files 111 and 121 is completed, the rear surface of the horizontal support beams 112 on the first wall 110 and the horizontal support beams 122 on the second wall 120 side The sheet piles 113 and 123 are disposed in contact with the front surface so that a filling space C capable of filling the soil 150 between the sheet piles 113 and 123 is formed.

At this time, it is preferable that the upper portions of the sheet files 113 and 123 are exposed above the water surface so that the installation work of the fixing stands 114 and 124 installed in the next step is not performed in water.

d) installing the fixing members 114 and 124 (Fig. 7);

When the installation of the respective sheet files 113 and 123 is completed, the fixing stands 114 and 124 are fixed to the front upper end of the H file 111 on the first wall 110 side and the rear upper side of the H file 121 on the second wall 120 side, .

It is preferable that the fixing brackets 131 and 124 are provided in advance with fixing brackets 131 for mounting the tie bar 130 in the next step.

The above steps a) to d) may be simultaneously carried out with respect to the first wall and the second wall, but after the operations of steps a) to d) for the first wall are completed, a) to c) The work of the step may proceed.

e) The tie bar (130)  Installing step (Fig. 8);

When the installation work for the first wall 110 and the second wall 120 is completed so that the filling space C is formed by the steps a) to d), the tie bars are fixed to the fixing tables 114, So that the distance between the wall 110 and the second wall 120 can be maintained constant.

f) sanding the soil 150 Filled  Step (FIG. 9);

Next, the gravel 150 is filled in the filling space C formed between the first wall 110 and the second wall 120 to form a waterwall having a predetermined thickness.

g) drainage and The wale band 115  Installation is a step (Figure 10);

When the water film wall having a predetermined thickness is formed by the filling of the gravels, a part of the water on the front surface of the H file 111 on the first wall 110 side The installation work of the wale band 115 is sequentially performed from the upper part to the lower part.

That is, at least a drainage operation is performed to a position where at least the wale band 115 is to be installed so that the upper part of the H file 111 is sufficiently exposed on the water surface, and then the welding operation is performed outside the water surface rather than under water. The installation of the wale band 115 is repeated so that the installation of the wale band 115 with respect to the entire length of the H file 111 is completed.

When the installation of the wale band 115 is completed, the construction of the underwater hypothecation of the present invention is once completed by installing the bracing rod 116 via the wale band 115. However, the existing underground layer 151 and the lower It is possible to further provide water walls 141 and 142 for excavating a part of the rock mass 160 and allowing the exposed H files 111 and 121 to be buried.
