Description

Retaining wall block and construction method of retaining wall block {RETAINING WALL BLOCK AND THE CONSTRUCTION METHOD FOR THE SAME}

[0001] The present invention relates to a reinforced soil retaining wall block with increased masonry stability and mutual bonding, and a method of manufacturing the retaining wall block,

In more detail, it is easy to make up and down for the construction of the retaining wall block, as well as adjacent retaining walls located on both sides of the retaining wall block.

The work required for the masonry by allowing the block and the upper and lower retaining wall blocks to be joined simultaneously with the mason without fixing members.

Precise masonry is possible by reducing time and minimizing the occurrence of gaps between adjacent retaining wall blocks.

The present invention relates to a reinforced soil retaining wall block with increased masonry stability and mutual bonding properties, and a method of manufacturing the retaining wall block.

In general, a retaining wall refers to a wall that is erected through a number of blocks so that the soil does not collapse by resisting earth pressure.

Due to the development and expansion of roads and complexes, cutting is being actively carried out, and there is a risk that the slope may collapse every year due to natural disasters and artificial cutting. There is a need for improvement measures to stabilize and maintain slopes in areas at risk of collapse.

In particular, a large amount of landslides and rockfalls occur due to heavy rains in the summer, infringing on the stable living rights of residents, and infringing on the living conditions of the people, such as bringing obstacles to vehicle traffic due to multiple collapses. There is an urgent need for measures to prevent collapse.

As a technology to prevent the collapse of the cut slope, a retaining wall block is stacked in front of the lower end of the cut slope, and an outer wall panel made of concrete is integrally formed on the foundation in front of the retaining wall block. A method has been proposed to reinforce the cut slope by installing a ring member to fix the other end of the nailing member to the inside of the cut slope.

However, in the conventional retaining wall structure, an outer wall panel must be manufactured in addition to the stacked blocks, and since the nailing member must be fixed to the stacked block and the outer wall panel, respectively, it takes a lot of time to construct and the cost is high. .

In particular, when planar activity is expected due to the discontinuity developing on the cut slope, or when instability of the cut slope is expected due to erosion of the cut slope, the construction cannot be performed smoothly, and backfilling between the stacked blocks and the cut slope is required. Because of the inconvenience, recently, stepped retaining walls for the purpose of suppressing active blocks and protecting the incision surface have been widely applied.

In the conventional stepped retaining wall block, the foundation is installed at the bottom of the cut slope, and then the retaining wall blocks are stacked, but the retaining wall blocks of each layer gradually retreat toward the cut slope toward the top, and the fault is constructed in a stepwise manner. It is a plan.

In addition to the installation of such a stepped retaining wall, a will-type retaining wall block, which is fixed by installing a panel in contact with a cut slope and introducing a tension force by installing an anchor on the panel, is also widely used.

However, in the conventional step-type retaining wall and the will-type retaining wall, after assembling and installing reinforcing bars at the site, a formwork is manufactured and attached to fix it, and the order of concrete placement, curing, and dismantling of the formwork is repeated to complete each step. As a result, a large amount of air is required, and the assembly-type prosthesis retaining wall has a relatively small cross-section, so if it directly resists the earth pressure of the collapsed back ground, it is light in weight and essentially uses an anchor to give tension and use a pin. There is a limit in application due to the addition of a fixing process.

As described above, step-type retaining walls and will-type retaining walls that are directly constructed on-site have a complicated construction process and take a lot of construction period, so additional collapse may occur during the construction period, and there are various assembly parts that occur in the existing prefabricated retaining walls. As the assembly process is not simplified, its use and application are limited.

The present invention has been devised to solve the above problems, and adopts a step-type retaining wall to form a retaining wall structure, and a standard retaining wall block manufactured in the factory is stacked on-site, and the retaining wall blocks connected to the left and right are stacked on top. By allowing the retaining wall blocks to be integrally fixed together with the horizontal and vertical bits and concrete to be poured, the retaining wall collapses even in natural disasters or storms and floods by maintaining a strong fixing force in the ground or rock even in sandy soils and weak soils. The purpose of this is to provide a retaining wall block that allows the cut slope to prevent collapse.

The above object has a constant inclination toward the top, at least one coupling jaw (106a) is formed protruding upward in a protruding shape at the top of the front side, and the seating portion 106b in a groove shape so as to be seated on the coupling jaw 106a at the bottom. ) And the front body 106 is formed; It is integrally formed at the rear of the front body 106, and at least one taper coupling hole 108a having an upper narrow light structure in a vertical direction is formed through, and at least one from the front body 106 toward the rear It is achieved by the retaining wall block 110, characterized in that it comprises a rear body 108 through which the bit hole 108b is formed through.

In addition, it is preferable to further include a tapered coupling groove 108c having an upper narrow light structure formed in a vertical direction on both side surfaces of the rear body 108.

On the other hand, the above object has a constant inclination toward the top, at least one coupling jaw (106a) is formed protruding upward in a protruding shape at the top of the front, and a seating portion in a groove shape so as to be seated on the coupling jaw (106a) The front body 106 having (106b) formed therein, and the front body 106 is integrally formed at the rear of the front body 106, and at least one tapered coupling hole 108a having an upper and lower light structure in a vertical direction is formed through at least one , At least one bit hole 108b is formed through from the front body 106 toward the rear, and the rear body 108 is formed with a tapered coupling groove 108c having an upper narrow light structure in a vertical direction on both sides.

The retaining wall block according to the present invention builds the retaining wall block on sandy soil and the soil with weak ground, and the horizontal bit and the vertical bit penetrating each retaining wall block are fixed to the ground, etc., thereby ensuring a strong fixing force of the retaining wall block. The retaining wall blocks that are vertically connected can be constructed integrally by pouring concrete into them, so that the left and right retaining wall blocks and the upper and lower retaining wall blocks have a strong binding force to each other.

In particular, since the concrete poured into the coupling hole by the tapered coupling hole has a multi-stage structure, it resists the earth pressure and has strong resistance to the left and right movements and the front and rear movements so that the soil does not collapse.
