Description

Reinforced soil retaining wall construction panel and its construction method

The present invention relates to a reinforced earth retaining wall construction panel and a method for constructing the same, while manufacturing the retaining wall construction panel by wet molding to block the structure of the panel so that the construction can be made in a block type, it is required in the construction process and discarded after use. Minimized subsidiary materials such as clamps and crutches, which can be used quickly, and can be quickly installed, and the panels can be secured by earth pressure by supporting the left, right, top and bottom panels firmly supported by connecting pins and uneven joints. The structure of the reinforcement insert groove can be prevented from falling, and the strip-shaped fiber reinforcement connected to the back of the panel is not separated, and the thickness of the panel itself can be made thin, and the weight of the panel can be reduced. External force absorbing grooves are formed in the left and right outer and middle portions of the panel to prevent breakage of the right corner.

In general, the reinforced earth retaining wall is a convex retaining retaining wall and panel-type retaining wall, and the reinforcement earth retaining wall of the block and panel is a compromise method, the technique for the construction method thereof is variously known. .

Among these, the block assembly type uses a relatively small dry or wet molded block, and the reinforcing material is mostly a geogrid (mesh). Since the block-assembled reinforcement earth retaining wall uses a small block, it is easy to install the bent portion due to the small radius of rotation, and has an excellent aesthetic effect. However, the most important block in the structure is the frictional resistance generated by the load of the stacked block. Since it is connected to the submerged or vertical vibration occurs, there is a disadvantage that the shear failure phenomenon that collapses as the friction force between the block and the grid or block and the block disappears.

On the other hand, the panel retaining wall has a disadvantage of having a small ratio of height to the height of the panel, so that it is not self-supporting, and it is supported by a crutch, which requires complex clamping and wedge work when the panel is assembled. Because of the construction of the panel is very difficult to assemble, the inversion of the panel at both ends has a disadvantage that the construction of the bent portion is difficult because the minimum rotation radius is quite large.

Prior arts related to the present invention include the "impact reinforcement earth retaining wall structure" of Patent No. 57983, the "retaining wall construction block" of Patent No. 803788, the "prefabrication earth retaining wall construction block" of Patent No. 674366, Patent Publication No. 2010-0100093 The "vegetation retaining wall panel" of No. 2, the "precast concrete products for reinforced soil retaining wall" of Utility Model No. 279966, the "retaining wall construction block which is easy to connect the strip-shaped fiber reinforcement" of Utility Model No. 453027, etc. are disclosed.

1 to 3, there is shown a general state of the retaining wall construction panel 1 and a laminated state for transporting the same, and a state in which the retaining wall is being constructed, and such a conventional reinforced soil retaining wall construction panel 1 is a panel. A connecting pin for anchoring the reinforcement is required in the connecting ring (2) protruding from the rear side, and a separate stump (3) is required to protect the connecting ring (2) during transportation and loading of the panel, and stacking of panels Due to the limited quantity, a large yard space is required, and a separate clamp or temporary shoring is required to maintain the gap between panels during construction and to maintain an upright state, and the clamping and dismantling operations of these clamps must be repeated during construction. In the process of laying backfilling soil (G) behind the panel (1) and compacting, it is attached to the back (2) of the panel (1). There is a disadvantage that it is difficult to squeeze a certain, and the problem is that the filling of the panel wall due to earth pressure after straight upright construction of the panel occurs.

4 shows the construction of the block type reinforced earth retaining wall to which the geogrid reinforcement is applied, which is connected between the upper and lower surfaces of the block 4 to connect the reinforcement 5 to the block with the load and frictional force of the block. In this way, in order to secure the joint area of the block 4 and the reinforcement 5, the back length of the block 4 must be secured sufficiently long, so that the weight of the block becomes excessively heavy, and the block is reduced to reduce the weight of the block. The through hole 6 is formed on the inner side, and the filling aggregate is required to fill the space of the through hole 6 and maximize the engagement area between the block 4 and the reinforcing material 5 and the compaction of the back filling soil. Backfill aggregates are also needed to prevent the fall of the city block, and the wall structure is secured by interlocking the blocks up and down, but there is a sense of stability. Due to the unstable structure in which the reinforcement is pressed between the blocks, there was a problem that the block was separated and fulled, and the block was lengthened before and after the length compared to the front area, which was bulky and heavy. Due to the block, the tensile force is small, there is a problem that the block is easily sheared or cracked by the external force.

5 is a block type reinforcement retaining wall to which the strip-shaped fiber reinforcement 7 is applied, which is a direct reinforcement insertion groove 8a without the need for a separate subsidiary material in the connection between the block 8 and the strip-shaped fiber reinforcement 7. Since it is fitted in the structure, there is an advantage of strengthening the binding force, no need for filling aggregates, preventing the block 8 from deviating or fulling phenomenon, and the situation that the block is turned over when compaction construction is alleviated, It can be seen that the improvement was made to minimize the space of the yard. However, the block 8 shown in FIG. 5 is also a dry formed non-reinforced block, and the tensile force is reduced, so that the shear or cracking of the block still remains.

The present invention has been made to solve the above problems, the object of the present invention is to take advantage of the block reinforced reinforcement earth retaining wall and panel construction reinforcement earth retaining wall can minimize the resources required to build the retaining wall, shorten the construction period If necessary, the vegetation or vegetation retaining wall can be constructed in harmony with the surrounding environment, and when the vegetation retaining wall is constructed, the vegetation on the entire surface of the retaining wall, as well as the partial vegetation or various patterned vegetation can be constructed. It is possible to solve the shortcomings of air shortening and manpower supply and demand by constructing equipment instead of manpower-dependent method, and wall slope can be applied from various vertical to gentle slope Corner part can be constructed at a predetermined angle.

Hereinafter, with reference to the accompanying drawings, preferred embodiments that do not limit the present invention will be described in detail.

6 to 12 illustrate the retaining wall construction panel according to the first embodiment of the present invention. As shown in the drawing, the panel P of the present embodiment has a front surface 10 exposed to the outside, a rear surface 20 in contact with the reinforcement soil, and left and right side surfaces 30 and 40, and a top and

bottom surface

50, 60, pin holes 52 and locking holes 62 are formed to be interlocked by the connecting pin 100; The pin hole 52 and the engaging hole 62 are formed on the left and right sides of the upper and

lower surfaces

50 and 60 with a predetermined distance from each other, and the upper and lower surfaces are formed on the left and right sides of the rear surface 20. A reinforcing member insertion groove 22 is formed in communication with the pin hole 52 formed at the left and right sides of the 50. A strip-shaped fiber reinforcement 200 is inserted into the reinforcing member insertion groove 22 to be anchored by the connecting pin 100. It is supposed to be.

The panel P according to the present embodiment has a width of about 1.2m and a height of about 0.6m, which is smaller than a conventional large panel but relatively larger than a conventional block, and has a thickness of about 15 to 20cm. It is considerably thin, making it light and easy to build by small lifting equipment.

In the panel P according to the present embodiment, the front surface 10 exposed to the outside is formed in a flat state, and the left and right sides of the front surface 10 are gradually thinner toward the outside, and the rear surface 20 is formed. Consists of a flat shape from one end to the other end.

The panel P according to the present embodiment does not protrude a separate metal connection hook or bracket on the rear surface 20 as in the conventional panel, so that several sheets are closely attached to each other as shown in FIG. This can minimize the logistics cost and the volume of the site for storage.

In the back surface 20 of the panel P according to the present embodiment, reinforcing material insertion grooves 22 are formed on the upper left and right sides, respectively, and the reinforcing material insertion grooves 22 have pin holes formed at the left and right sides of the upper surface 50. Each of the reinforcing member insertion grooves 22 is in communication with each other so that the strip-shaped fiber reinforcement 200 is inserted into the pinholes 52 of the upper surface 50 when inserted in a standing state (whether folded or not folded in half width). By being anchored by the connecting pin 100, the band-shaped fiber reinforcement 200 is formed by a member for interlocking the connecting pin 100, that is, the panel up and down, without using an auxiliary material such as a separate bracket or a connecting ring. The panel P can be anchored to the front surface of the retaining wall.

The inner side of the reinforcing member insertion groove 22 is formed in the form of inner narrow external light narrowing the width of the left and right, the outer side, that is, the width of the left and right toward the rear surface 20 to facilitate the insertion of the strip-shaped fiber reinforcement 200 Of course, the strip-shaped fiber reinforcement 200 anchored at the end of the panel P can be naturally spread on the reinforcement soil in contact with the back surface 20 of the panel P, thereby preventing the compaction of the backfilling soil and providing maximum frictional resistance. To make it work.

In addition, since the width of the reinforcing member insertion groove 22 is made of various standards of the band-shaped fiber reinforcement 200 currently being used, it is preferable to form a sufficient height so that all of them can be used.

In the present embodiment, the left and right side surfaces 30 and 40 of the panel P are formed with concave-

convex coupling portions

32 and 42, respectively, to form continuous concave-convex coupling between adjacent panels. The front of the reinforcement soil is visible to the naked eye or to prevent the reinforcement soil is lost to the front, the coupling of the concave-convex coupling portion (32, 42) formed on the left and right side (30, 40) is a connection pin In addition to the vertical coupling by the (100) and the left and right adjacent panels (P) and the panel (P) laying the backfilling soil by allowing to maintain a stable state without the use of additional materials such as clamps or shoring When the compaction work is performed using the equipment afterwards, the panel P is not inverted or a local deformation does not occur due to the impact of the compaction work, thereby enabling easy construction.

In the upper surface 50 of the panel P according to the present embodiment, a pin hole 52 into which the connecting pin 100 is inserted is formed, and the pin hole 52 is tapered so that the diameter gradually decreases toward the lower inner side. Formed in a jin form to facilitate the insertion of the connecting pin 100 in the construction site as well as preventing damage during production.

In addition, in the present embodiment, the external

force absorbing grooves

54 and 56 are formed at the middle portion and the left and right sides of the upper surface 50 slightly lower than the upper surface 50, so that the right angle portion (left and right edge portions) when the panel is stacked. In order to prevent breakage, the vertical shear force applied to the panel is not concentrated on the left and right edges.

In addition, a locking hole 62 is formed in the lower surface 60 of the panel P according to the present embodiment, and the upper portion of the connection pin 100 inserted into the pin hole 52 formed in the upper surface of the lower panel P. The exposed part is inserted into the upper panel and the lower panel to be interlocked with each other. The locking hole 62 is also formed in a tapered shape that narrows toward the inside to facilitate the insertion of the connecting pin 100, but the upper panel is connected to the connecting pin 100. The front part of the locking hole 62 is formed in a vertical state so that the latched state can be stably maintained, and the locking hole 62 is formed long in the horizontal direction so that it is connected even when the curved retaining wall is constructed, not the straight retaining wall. Insertion of the pin 100 can be easily made.

On the other hand, when the retaining wall is constructed using the panel according to the present embodiment, as shown in FIG. 11, the panel P may be blocked and most of the construction may be constructed in a stacking manner. It is preferable to construct the separation of the retaining walls (W1, W2) of the left and right by using a half-width panel (P ') so as to secure.

Panel P according to the present embodiment is wet, that is, sand and cement, aggregates, etc. are mixed in a predetermined ratio, and the appropriate amount of water is poured into the mold after pouring into the mold to cure, produced in this case As shown in FIG. 12, it is preferable to arrange the rebar 70 horizontally and vertically to improve structural strength, and the horizontally arranged rebar 70 is rearward of the pin hole 52. It is preferable to allow the cross-shaped fiber reinforcement 200 to be dispersed so that the stress is not concentrated on the connection pin 100 at the portion of the panel when the tensile force of the strip-shaped fiber reinforcement 200 is applied.

13 shows a retaining wall construction panel according to a second embodiment of the present invention.

The panel P according to the present embodiment has a front surface 10 exposed to the outside and a rear surface 20 in contact with the reinforcement soil and left and right side surfaces 30 and 40, and connected to the upper and

lower surfaces

50 and 60. Retaining wall construction panel P in which the pin hole 52 and the locking hole 62 are formed so that it may be interlocked by the pin 100; The pin hole 52 and the locking hole 62 are formed on the left and right sides of the upper and

lower surfaces

50 and 60, respectively, at a predetermined distance from each other, and the upper and lower surfaces of the rear surface 20 on the left and right sides thereof. A reinforcement insertion groove 22 is formed in communication with the pin hole 52 formed at the left and right sides of the 50 so that the strip-shaped fiber reinforcement 200 is inserted into the reinforcement insertion groove 22 and connected by the connecting pin 100. To be anchored, vegetation grooves 58 open to the rear surface 20 side are formed on the upper surface between the pin holes 52 on the left and right sides to allow plant growth.

In this embodiment, the vegetation groove 58 also functions as the external force absorbing groove 54 in the first embodiment.

Preferably, the vegetation groove 58 is formed in a form inclined downward toward the bottom of the rear surface 20 of the panel (P), the vegetation soil (preferably in a separate bag) It is filled, and the plant is implanted inside the bag to allow the plant to grow to the front of the retaining wall.

In the present invention, the vegetation groove 58 may be manufactured in various shapes and various sizes in addition to the downwardly inclined form of the embodiment shown in FIG.

FIG. 14 is a cross-sectional view of a vertical retaining wall constructed by combining the vegetation and vegetation panels according to the first and second embodiments of the present invention described above, and FIG. 15 illustrates the first and second embodiments of the present invention described above. A cross-sectional view of the inclined retaining wall constructed by combining the vegetation and vegetation panels is shown.

As shown in Figs. 14 and 15, the retaining wall constructed using the panel of the present invention can construct an inclined retaining wall having a predetermined inclination as well as a vertical, and retains the partial vegetation or vegetation retaining wall in harmony with the surrounding environment. When constructing an inclined retaining wall as shown in FIG. 15, the weight of the panel is reduced, and interlocking by the left and right panel side uneven coupling parts and the connecting pin coupling structure between the upper and lower panels separate the temporary material (clamp or There is an advantage that can facilitate the inclined construction of the panel without the support.

16 and 17 illustrate a state in which the strip-shaped fiber reinforcement 200 is connected to the panel P according to an embodiment of the present invention, and FIG. 16 shows each reinforcing member insertion groove formed at the left and right sides of the panel P. FIG. The band-shaped fiber stiffener 200 is individually bound to the zigzag pattern in FIG. 22, and FIG. 17 shows one band-shaped fiber stiffener so as to be connected to the respective reinforcing member insertion grooves 22 formed at the left and right sides of the panel P. The binding method of the strip-shaped fiber reinforcement 200 in a state where the bundle is continuously bound can be variously selected according to the situation of the construction site (whether the height of the retaining wall or the backfilling distance is secured), so that the horizontal laying interval of the strip-shaped fiber reinforcement is varied. It is shown that economical design is possible by adjusting it.

18 is a perspective view showing a state in which a retaining wall is constructed on the cut surface slope with a panel according to an embodiment of the present invention, and when there is a rock or other obstacle on the cut surface slope S, reinforcement soils G are laid. Since the distance (backfill space) is short, the band-shaped fiber reinforcement 200 is not sufficiently exerted to be simply buried in the reinforcement soil (G). By binding the rear end of the 200 with a connection nut or the like, it is possible to exert sufficient supporting force. In FIG. 18, the interval between anchors (nail) can be freely adjusted according to the ground conditions of the cut slope, so that the construction is easy, and the band-like fiber As the reinforcing material is connected to the anchor, resistance to external force is increased, and it is also possible to use viscous soil such as mountain soil or dark rock scattered on the construction site instead of sandy soil.

Further, as shown in FIGS. 19 and 20, the connection of the strip-shaped fiber reinforcement 200 may be three-dimensionally connected to the anchor 300 embedded in the rock, and so on, thereby all the strip-shaped fiber reinforcement 200 supporting the front wall may be connected. It can be connected to the anchor 300 without missing, can be constructed with a minimum amount of cut and back filling material of the slope, the slope of the front wall can be adjusted according to the slope of the cut slope.

By adjusting the inclination of the front wall, it is possible to reduce the cut amount of the cut slope and the fill amount of the back filling material, and when the front wall is inclined toward the cut slope, the compressive force and the band-shaped fiber due to the wall weight transmitted in the slope direction The shear strength of the slope is enhanced by the tension of the reinforcement, and the load applied in the vertical direction of the front wall may be alleviated.

In addition, by using the vegetation panel according to an embodiment of the present invention by constructing the retaining wall on the cut surface slopes can be harmonized with the natural environment of the surrounding surrounding the green wall of the panel wall.
