On the other hand Figure 7 is a plan view showing a reinforcing material according to an embodiment of the present invention, Figure 8 is a cross-sectional view showing a reinforcing material according to an embodiment of the present invention,

As shown in the drawing, the reinforcing member 300 is a band-shaped reinforcing member 310, and the external friction member having a plurality of friction protrusions 312 formed in a constant arrangement on the outer surface so as to increase the friction force when embedded in the slope 600 ( 311 and an inner core 313 positioned inside the outer friction member 311 to increase the strength of the reinforcing material 300.

The inner core 313 is preferably made of polyester, glass wool, glass fiber so that the strength is increased and the belt-shaped reinforcement 310 can be reduced in weight.

Meanwhile, the band-shaped reinforcement 310 configured as described above is configured to be connected to two through the joint member 314 of a thin synthetic resin material, and is connected to the T-shaped block 100 or the I-shaped block 200 according to the supporting strength of the block. Two or more may be used, or the joint 314 may be cut and used separately.

On the other hand, when the installation length of the reinforcement 300 is formed long length of the reinforcement 300 may be used as a mesh reinforcement 320, as shown in Figure 9, if the length of the installation is short, such as incision paper, anchored to the block through the steel ( (Not shown) can be fixed to the slope.

Referring to the construction method of the retaining wall structure of the present invention configured as described above through various embodiments are as follows.

First, the bottom of the slope 600 formed by cutting or filling is laid out, and then the foundation concrete 500 is constructed.

Thereafter, the T-shaped block 100 and the I-shaped block 200 are arranged in the width direction of the slope 600 on the upper portion of the foundation concrete 500.

Here, as shown in FIG. 10, the construction may be performed by alternately arranging the T-shaped block 100 and the I-shaped block 200, and when the T-shaped block 100 and the I-shaped block 200 are alternately arranged, the T-shaped block. The front of the front portion 110 of the (100) to the front of the expansion front portion 210 of the I-shaped block 200 is constructed to abut.

In the case where the T-shaped block 100 and the I-shaped block 200 are alternately installed, the I-shaped block 200 is constructed behind the T-shaped block 100 and supported by the T-shaped block 100, thereby preventing the earth pressure. By this, the installation form of the block structure can be prevented from being deformed or collapsed locally, and the aesthetic effect is also excellent by the regular arrangement.

Meanwhile, when the T-shaped block 100 and the I-shaped block 200 are arranged in one stage as described above, a filling material is installed at the rear of the arranged blocks, and the locking groove 121 formed in the rear portion 120 of the T-shaped block 100 is formed. ) And the reinforcing material 300 is connected to the engaging portion 210 of the I-shaped block 200, and then extends to the rear to install the filling material and compact the filling material.

Then, the fitting protrusions 150a and 150b and the fitting grooves 151a and 151b are coupled to the upper portions of the T-shaped block 100 and the I-shaped block 200 to form other T-shaped blocks 100 and I-shaped blocks ( After stacking 200, the connecting rod 400 is inserted into the through-holes 11a and 111b to connect the two upper and lower blocks.

Thereafter, the filling material is laid in the rear of the stacked blocks as described above, the reinforcing material 300 is installed, and the blocks are stacked again, and then the steps of connecting through the connecting rod 400 are repeatedly constructed to build the blocks to the design height. do.

Meanwhile, in the present invention, the T-shaped block 100 and the I-shaped block 200 are arranged in the width direction of the slope 600, and the T-shaped block 100 and the I-shaped block 200 are arranged in blocks of each other. Since the T-shaped block 100 and the I-shaped block 200 can be arranged alternately, they can be arranged in various forms as shown in FIG. 11 according to the construction site conditions.

As shown in the figure, when the T-shaped block 100 and the T-shaped block 100 are arranged adjacently, the concave-convex coupling portions 140 formed on both sides of the front portion 110 of the T-shaped block 100 abut each other. Arrange by

At this time, it is possible to adjust the arrangement angle of the neighboring T-shaped block 100 through the uneven coupling portion 140 formed on both sides of the front portion 110 of the T-shaped block 100.

That is, when the coupling angle of the neighboring T-shaped block 100 relative to the front portion 110 of the T-shaped block 100 is smaller than the horizontal angle, the first inclined coupling portion 141 is arranged to abut.

In addition, when the T-shaped block 100 is arranged such that the horizontal coupling portion 142 of the uneven coupling portion 140 abuts, the neighboring T-shaped block 100 can be coupled horizontally,

When the coupling angle of the T-shaped block 100 is larger than the horizontal angle to be coupled, the second inclined coupling portion 143 is arranged to abut so that the construction can be appropriately corresponding to the rotation radius of the slope 600.

Meanwhile, when the slope 600 is horizontally formed in the width direction, the I-shaped block 200 having the extended front portion 210 having a longer width direction than the front portion 110 of the T-shaped block 100 is continuously formed. By arranging it, it is possible to construct a smaller number of blocks than when the T-type block 100 is arranged so that the construction can be performed more quickly.

When the I-shaped block 200 is continuously arranged, the recessed grooves 211 and the protruding pieces 212 formed on both sides of the expansion front part 210 are fitted to each other to be coupled to each other to form the neighboring I-shaped block 200. )).

In the present invention constructed as described above, when the slope forms a curved section in the width direction, the T-shaped blocks 100 are arranged and constructed, and when the straight sections are formed, it is preferable to construct the I-shaped blocks 200.

It is possible to appropriately correspond to the radial width of the slope by constructing the angle-adjustable T-shaped block 100 in a curved section, the expansion of the I-shaped block 200 than the front portion 110 of the T-shaped block 100 Since the width of the front portion 210 is larger, a faster construction is possible by constructing the I-shaped block 200 in a straight section, and the type of blocks installed according to the widthwise shape of the slope can be appropriately adjusted, which is very reasonable. This can be easily constructed, and the installation amount of the reinforcing material 300 connected to the block is reduced by reducing the number of installation of the block than when installing only the T-shaped block 100 is to reduce the material cost.

Meanwhile, when the T-shaped block 100 and the I-shaped block 200 are arranged in one stage as shown in FIG. 11, a filler is formed at the rear of the T-shaped block 100 and the I-shaped block 200, and formed on the rear portion 120. After connecting the reinforcing material 300 to the locking portion 220 of the locking groove 121 and the I-shaped block 200, and extends to the rear to install on the filling material and compacts the filling material.

Then, the fitting protrusions 150a and 150b and the fitting grooves 151a and 151b are coupled to the upper portions of the T-shaped block 100 and the I-shaped block 200 to form other T-shaped blocks 100 and I-shaped blocks ( After stacking the 200) by inserting the connecting rod 400 connects the upper and lower two blocks.

Since the filling material is installed in the rear of the T-shaped block 100, the I-shaped block 200 stacked as described above, the reinforcement 400 is installed, and the T-shaped block 100, I-shaped block 200 again stacked After completing the step of connecting the stacked blocks through the connecting rod 400 is completed by building the blocks to the design height.

On the other hand, the present invention according to the embodiment as described above can be closed by further installing a cover block (not shown) in the T-shaped block 100 and the I-shaped block 200 located at the top of the building blocks.
