The present invention relates to a step block and a method for constructing the same.

Specifically, the present invention relates to a step block for a bed retaining wall and a method of constructing the same, which form a staircase on a bed retaining wall to improve access to a stream from an adjacent normal or inclined surface of the bed.

Retaining walls are constructed in order to solve the problem that soil is lost or flooded by river water or rainwater on the adjacent law surface or slope. The retaining wall is mainly formed by stacking soil and the like to separate the dike and the river, or to build a stone or concrete block according to the place or purpose. In other words, the conventional revetment wall retaining method is to install a concrete structure, to build a stone to form a stone (mason), or to build a block for the bottom retaining wall, and at the same time take a method of properly placing concrete.

However, the general shore retaining wall is constructed in the form of a straight wall on the adjacent surface of the river. That is, since the retaining wall is inclined with respect to the embankment in the state normally installed on the surface, it is not easy to approach a lake from a dike.

The utility model No. 260417 shown in FIG. 9 constitutes a staircase with an upper left staircase (1), a lower left staircase (2) and an upper right staircase (3), and a lower right staircase (4), with two interlocking sections (5) between them. (5 '), and each vertical surface (6) proposes a stepped revetment block consisting of a natural rock-shaped uneven surface. Here, the unexplained reference numeral “7” in FIG. 9 is a binding hole, and the reference numerals specified in FIG. X refer only to the technical configuration of FIG. 9 and do not affect other drawings.

However, the construction of this revetment block is somewhat complicated and difficult due to its specificity. In addition, since the construction is possible only on the inclined surface can be secured access to the lake, but can not be built in a straight wall.

Another stabilizing step stair block of the prior art Utility Model No. 344594 is shown in FIG. The stair block has a bottom portion 11 formed so that the cutting grooves (11a) are arranged in a straight line along the longitudinal direction at both side edges; A front part 12 extending vertically from the front edge of the bottom part 11; Disclosed is a stair block for the relief consisting of; connecting ring 20 buried in the bottom portion 11 so that the hook portion 21 is exposed in the cutting grooves 11a. Here, the unexplained reference numeral 11b of FIG. 8 is a drainage hole, 13 is a supporting wall, 13a is a locking jaw, 22 is an anchor part, 101 is a basic rubble, 102 is a basic concrete, "103" refers to the nonwoven fabric, "105" refers to the embankment, "106" refers to the shackle, and "109" refers to the front surface, and the symbols shown in FIG. 8 refer only to the technical configuration of FIG. 8 and do not affect other drawings. No.

However, the block of the Utility Model No. 344594 is more complicated in shape than the block of the Utility Model No. 260417. In addition, the technical configuration employed is also excessively disadvantageous in terms of cost, and thus the construction time is low and the construction period is long due to a large amount of work required.

On the other hand, as another prior art, registered utility model No. 336702, which is not shown in the ecological lake, is open on both sides of the staircase frame formed with the inner space portion, the movement is formed on the front vertical plate of each floor to communicate with the inner space portion It is characterized in that it comprises a plurality of brackets fastened to the front vertical plate along the passage, the moving passage and holding the band-shaped support medium, the filling member is formed to form a gap in the inner space of the stepped frame body; .

But this ecological retreat is not a retaining wall. That is, only the frame itself is stacked in a stepped shape, and as the height of the retaining wall increases, the quantity of the frame forming the lowest end increases exponentially, thus requiring excessive overall costs.

While many conventional embodiments of the above-described revetment method suggest various embodiments, high access to rivers is not secured and accompanying problems are accompanied according to the modified example.

The present invention has been made in view of the various problems that have been difficult or impossible to solve by the prior art in the technical field to which the present invention belongs.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 8. In the following description, terms used to refer to each part of the present invention are terms defined in consideration of functions in the present invention, which may vary according to customs in the art to which the present invention belongs. In addition, the same code | symbol is used for the same component which comprises each part of this invention as much as possible through FIGS.

As shown in FIG. 1, the staircase block 100 of the present invention includes a main shaft portion 10 and a vertical shaft portion 20.

The main shaft portion 10 is formed in a substantially rectangular parallelepiped shape. Therefore, the main shaft portion 10 has a rectangular parallelepiped. And preferably, the main shaft portion 20 is longer than the horizontal width of the longitudinal length.

In addition, the fitting groove 11 and the fitting portion 12 are formed in one side surface 10l and the other side surface 10r of the main shaft portion 10, respectively. The fitting groove 11 is formed by recessing inwardly at the side 10l of the main shaft portion 10, and the fitting portion 12 is outwardly at the other side 10r of the main shaft portion 10. It is formed by protruding. Preferably, the upper fitting groove 11 has an entry depth equal to the protrusion height of the upper fitting portion. And the fitting groove 11 and the fitting portion 12 has a constant cross-section. The illustrated embodiment shows that the upper fitting groove 11 is formed on the left side surface 10l of the main shaft portion 10 and the upper fitting portion 12 is formed on the right side surface 10r of the main shaft portion 10. However, the present invention is not limited thereto, and the fitting portions may be formed on the left surface 10l of the main shaft portion 10, and the fitting grooves may be formed on the right surface 10r of the main shaft portion 10.

The upper fitting groove 11 and the fitting portion 12 are to more firmly couple the vegetation block 200 to the step block 100, respectively.

In addition, the groove 13 is formed inwardly in the upper surface 10t of the main shaft portion, and the convex portion 14 protrudes outwardly in the bottom surface 10b. The groove 13 and the convex portion 14 are to achieve the block (100, 200) is more firmly coupled by fitting the convex portion 14 to the groove 13 during the construction of the retaining wall.

The vertical shaft portion 20 extends from the front face 10f of the main shaft portion 10. The vertical axis portion 20 has its upper surface 20t in contact with the upper surface 10t of the upper main shaft portion 10. In addition, the bottom surface 20b and one side 20l of the longitudinal axis 20 are in contact with the bottom surface 10b and one side 10l of the upper main shaft 10.

In addition, the illustrated embodiment shows that the left surface 20l of the vertical axis portion 20 is in contact with the left surface 10l of the main shaft portion 10. However, on the contrary, the step block 100 may be formed such that the right side surface 20r of the vertical axis portion 20 is in contact with the right side surface 10r of the main shaft portion 10.

The longitudinal axis portion 20 is formed in a substantially rectangular parallelepiped shape, preferably as shown in the stepping step 29 is formed. The stepping step 29 may be formed by pulling the upper surface 20t downward (recessed) around the parent where the left surface 20l and the upper surface 20t of the longitudinal axis portion 20 meet. Therefore, the cross section of the longitudinal axis part 20 has a uniform "┛" shape as a whole.

Similarly, if the right side surface 20r of the longitudinal axis portion 20 is formed to be in contact with the right side surface 10r of the major axis portion 10, the upper stepping step 29 will be formed on the right side of the longitudinal axis portion 20, At this time, the cross section of the longitudinal axis portion 20 will be formed in a "┗" shape.

Since the step block 100 of the present invention has a relatively simple shape as compared to the conventional block, the manufacturing (mass production) is easy to manufacture and easy to handle, the construction is also high.

Hereinafter, a method of constructing a bed retaining wall of the present invention having a staircase will be described.

First, before constructing the blocks 100 and 200, the river bed on which the retaining wall is to be positioned is stopped. After placing the foundation concrete on the stationary bottom surface, it is cured for a certain period to obtain a smooth foundation surface.

Next, the blocks 100 and 200 for forming the lowermost end of the retaining wall are arranged on the base surface.

Specifically, first, the stair block 100 is located. At this time, preferably, the longitudinal axis 20 is directed toward the river 400. The reason is that when the longitudinal axis portion 20 on which the stepping step 29 is formed faces the lake bank surface, that is, the bank side, the stepping step 29 is embedded in the ground by the back filling process.

Subsequently, the vegetation block 200 is coupled to both sides of the stair block 100.

Both sides of the vegetation block 200 is formed with fitting portions 212 and fitting grooves 211 corresponding to the fitting groove 11 and the fitting portion 12 of the stair block 100, respectively. The fitting groove 211 and the fitting portion 212 of the vegetation block 200 is fitted to the fitting portion 12 and the fitting groove 11 of the stair block 100 to firmly combine both blocks (100, 200). In the same way, the same vegetation block 200 is coupled to the left and right sides of both vegetation blocks 200.

Here, the shape of the vegetation block 200 will be described with reference to FIG. 2. In the upper surface of the vegetation block 200, grooves 213 are formed in a lattice shape. In addition, a linear convex portion 214 protrudes from the bottom of the vegetation block 200. The upper convex portion 214 is formed to fit in the groove 213.

 And vegetation grooves 290 are formed on both sides of the vegetation block 200. The vegetation groove 290 is preferably a semi-cylindrical shape, but may be formed in other shapes, such as square, hexagon, octagon. In addition, the vegetation groove 29 has a front and rear shape, and the tip is higher than the rear end. The vegetation groove 290 is formed in a tapered shape in which the cross-sectional area gradually decreases from the front side to the back side or vice versa. Preferably, the vegetation groove 290 has a rear cross-sectional area is slightly larger than the front cross-sectional area. The reason is that if the front of the vegetation groove 290 is wide and the rear is narrow, the soil leakage is increased to the front, and the roots of the herbaceous plants are hard to work inside the embankment. However, in this case, since the herbaceous plants may be difficult to grow through the front surface of the vegetation groove 290, the cross section of the vegetation groove 290 is appropriately formed according to the situation.

Both sides of the vegetation block 200 is formed with a fitting groove 211 and the fitting portion 212 in parallel with the vegetation groove 290. The upper fitting portion 212 is formed to fit in the fitting groove 211. As shown, the formation of the vegetation groove 290 is prioritized, and the fitting groove 211 and the fitting portion 212 are partially cut by the vegetation groove 290.

In addition, on the rear surface of the vegetation block 200, several friction grooves 215 are drawn in to increase the contact area with the normal surface.

Vegetation grooves 290 formed on both sides of the vegetation block 200 may be used as a moving space, a habitat space, an evacuation space, a spawning space, and the like. In addition, the two vegetation grooves 290 form one integral vegetation hole 291 (Fig. 8). The vegetation hole 291 is used as a growth space of the herbaceous plant 500, and the root of the herbaceous plant 500 is approached to the dike through the vegetation hole 291. The vegetation hole 291 may be used as an ergonomic space, and the reefs may be formed by the underwater plants grown through the vegetation hole 291.

On the other hand, if the lowermost blocks (100,200) of the retaining wall is installed, by filling the thick aggregate and fine aggregate between the rear surface and the normal surface of the blocks (100,200) to stabilize the built state of the retaining wall.

And the other stair block 100 is stacked on the top of the bottom of the stair block (100). At this time, the step block 100 located at the top of the stack to move slightly in the lateral direction. That is, the lower side of the main shaft portion 10 of the stair block 100 located at the upper end is positioned at the center of the upper surface 10t of the main shaft portion 10 of the stair block 100 positioned at the lower end. This is to form a step as a stepping step 29 of the lower step block 100 and a stepping step 29 of the upper step block 100.

After constructing the stair block 100 in this way, by combining the vegetation block 200 on both sides in the same manner as described above to build a second end of the retaining wall, and between the rear and the adjacent surface of the blocks (100,200) Fill the coarse aggregate and fine aggregate.

By repeating the above steps several times sequentially, the bottom retaining wall 310 as shown in FIG. 3 is completed. The retaining wall 310 has blocks 100 and 200 stacked vertically so that the bottom retaining wall 310 is constructed in a straight wall shape.

When the blocks 100 and 200 are constructed, if the upper blocks 100 and 200 are retracted slightly in the rear direction compared to the lower blocks 100 and 200 and stacked, the stepped (sloped) retaining walls 320 as shown in FIG. 4 may be constructed. That is, the upper stair block 100 is slightly moved laterally compared to the lower stair block 100, and may be laminated with a distance slightly separated from the rear surface 10rr direction of the main shaft portion 10. At this time, the groove 213 of the vegetation block 200 is also formed slightly spaced in the rear direction from the center as shown in FIG. In the same manner, the recess 13 of the stair block 100 is also formed to be spaced apart in the direction of the rear surface 10rr of the main shaft portion 10.

6 is a perspective view showing a step block according to another aspect of the present invention.

The stair block 100 shown in FIG. 6 is the same as the stair block 100 above, except that the main shaft portion 10 is formed in a pair so as to face each other. In addition, although not shown in the embodiment of FIG. 1, for example, as shown in FIG. 3 or 6, the stair block 100 has an upper surface of the main shaft portion 10 to form the railing 600. Handrail holes 10h connecting the bottom and the bottom may be drilled. In addition, a non-slip 10n may be formed in the stepped stage 29 to prevent slipping.

Such a step block 100 is to build a retaining wall 330 having a bent portion as shown in FIG. The illustrated retaining wall 330 does not affect the flow of the river water because the step block 100 is drawn by a predetermined distance from the retaining wall 330. That is, the staircase block 100 of FIG. 3 may act as a kind of resistance to the flow of the river water. As shown in FIG. It has no effect.

In addition, the inclined (stepped) retaining wall 340 as shown in FIG. 8 can be constructed using the block of FIG. 6. This retaining wall 340 example construction is the same as the retaining wall construction example shown in FIG.

As described above, the step block 100 of the present invention and the retaining wall 310, 320, 330, 340 construction method using the same have been presented as at least one or more embodiments. However, since the present invention can be variously changed and implemented without departing from the spirit and construction described in the claims below, such modified embodiments are also belong to the present invention.

The present invention including the above configuration improves access to the river by forming a step on the river retaining wall.

In addition, it is possible to form a staircase on the riverbed retaining wall with a relatively simple configuration and method, and both a straight wall type and an inclined structure can be used.
