Description

Technical Field [0001] The present invention relates to a block for civil engineering structures,

TECHNICAL FIELD The present invention relates to a block for a civil engineering structure used for constructing a reinforced earth retaining wall for a flat site on a slope, a fencing pillar or a pillar, and a construction method of the civil engineering structure using the same. The reinforcing material insertion groove is formed on the upper surface of the block so that the band-like fiber reinforcing material is connected in a ring shape without using any additional material, thereby maximizing the bonding force and the connection strength between the block and the reinforcing material. At the same time, local damage or stress concentration of the reinforcing material does not occur, so that the civil engineering structure having excellent durability can be constructed.

Generally, geogrid reinforcement is mainly used in block-type reinforced earth retaining walls used to prevent soil loss or to provide a flat site on a slope. This geogrid reinforcement is formed by lattice-shaped (mesh-shaped) And consists of longitudinal ribs and transverse ribs.

As a method of producing the geogrid having such a lattice structure, there are weaving, stretching after perforation, laser welding, heat welding, ultrasonic welding, etc. Since the geogrid produced in this way has a lattice shape, So that it is relatively easy to connect to the retaining wall block, and the coefficient of friction in the soil is large.

However, the methods using the geogrid reinforcement generally have a lower contact strength at which the warp meets warp than the tensile strength of the product, so that the connection strength with the block is far lower than the tensile strength. In addition, It is necessary to carry out an additional process using the equipment, so that the production cost is higher than that of the strip-type fiber reinforcement in the method of extrusion molding.

In addition, in the method of connecting the geogrid reinforcement to the block, the connection strength between the block and the stiffener is not high by interposing it between the upper and lower blocks and fitting the connecting pin. Particularly, in the case of the curved retaining wall, Since the geogrid reinforcement needs to be expanded and deployed, when the geogrid reinforcement is expanded between the adjacent blocks, only the tip of the geogrid reinforcement is pressed against the block positioned above the protrusion, In the vertical distribution of the blocks constituting the retaining wall, the geogrid reinforcement on the lower side of the retaining wall has a high binding force with the block due to the load of the plurality of blocks located on the upper side. On the other hand, In the upper part Press, and the disadvantage that the weight of the block relative to the light falling cohesion and strength of the connection block and that, there is a long-term reliable connection strength is maintained difficult due to damage of the connection reinforcement is pressed between the upper and lower blocks.

Therefore, it is an urgent need for a new type civil engineering structure block which has excellent bonding strength with the block and excellent in workability, while using an inexpensive staple fiber reinforcing material instead of the geogrid reinforcement.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 show a standard block for a civil engineering structure according to an embodiment of the present invention.

In the standard type block 1 of this embodiment, Upper, lower  Between blocks Interlocking  A connection pin insertion hole 12 into which the connection pin 3 for insertion is inserted is formed, The through hole (14)  And Of the through-hole (14)  A rearwardly open rear stiffener The insertion groove 16  Is formed, Of the through-hole (14)  In the forward direction, The insertion groove 18  So that the reinforcing material (2) In the insertion grooves 16,  And can be connected in the form of a ring.

In this embodiment, The through-  Two blocks are formed on both sides of the block, extending in the direction of the block back side and block side, forming an L shape.

The standard block 1 of the present embodiment includes a top surface 10 and a bottom surface 20 in a generally flat state, a front surface 30 that is split to have a surface texture of natural stone, And a rear surface 60 made of tapered left and right side surfaces 40 and 50 and two projections 62 and one indentation 64. [

In addition to the natural stone texture as shown in the drawing, the front surface 30 of the standard block 1 may be formed in various patterns by a molding frame.

The standard type block of the present embodiment is formed of concrete so as to have a weight of about 30 to 50 kg, and can be constructed manually by hand without using equipment to construct a retaining wall, a fence, etc. For convenience of transportation, And gripping grooves 42 and 52 are formed at the rear end thereof.

The standard type block of this embodiment is designed such that the weight of the block is relatively light in comparison with the area of the generally flat and large surface area forming front surface 30 of the retaining wall so that improvement in workability of the block- And the material cost can be reduced.

In other words, the standard type block according to the present embodiment has a structure in which the shape of the flat cross-section is lightweight compared with the generally flat front surface 30. More specifically, the L- The light weight can be reduced by the shape of the through hole 14 and the thin and deep projection 62 extending in a tapered shape on both sides of the rear face of the block 1 and the deep and waved indentation 64 between the projection 62 You can do it.

In order to compensate for incomplete grasping due to the depth of the grasping grooves at the rear of the grasping grooves 42 and 52, protrusions protruding outwardly in the direction opposite to the grasping grooves 42 and 52 44 and 54 are formed to prevent the fingers from being separated from the gripping grooves 42 and 52.

In the present embodiment, three connection pin insertion holes 12 are formed on both sides of the upper surface 10, and the connection pin insertion holes 12 are arranged in a diagonal direction toward the rear outer side when seen in plan view The rear engagement angle and the rotation angle of the block located at the upper portion can be made different depending on which insertion hole 12 the connection pin is inserted.

6 to 8, when the upper block 1b is constructed so as to be perpendicular to the lower block 1a, the upper block 1b is formed in a manner of being offset from the lower block 1a The connecting pin 3 is inserted into the connecting pin insertion hole 12c at the rear end of the upper block 1b and the lower portion of the connecting pin 3 is inserted into the through hole 14 of the lower block 1a. The upper block 1b is prevented from being pushed forward while being perpendicular to the lower block 1a.

9 to 11, when the upper block 1b is constructed to be retracted rearward with respect to the lower block 1a, the upper block 1b is divided into the lower block 1a, The connection pin 3 is inserted into the connection pin insertion hole 12a at the front of the upper block 1b so that the lower portion of the connection pin 3 is formed in the lower block 1a The upper block 1b is retreated relative to the lower block 1a while being prevented from being pushed forward and the connection pin 3 is prevented from being pushed forward by the intermediate connection pin insertion hole 7 and the inclination angle shown in FIG. 9 by inserting it into the recess 12b.

12, the insertion position of the connecting pin may be selected according to the curvature formed by the retaining wall. In this embodiment, the connecting pin insertion hole 12 is formed in the block 1 and the through holes 14 in which the connecting pins 3 inserted in the connecting pin inserting holes 12 are engaged are located inside the connecting pin inserting holes 12 on both the left and right sides, The connecting pin and the through hole can be interlocked with each other while maintaining the inclination of the wall of the retaining wall due to the rear bite of the block 1b as a whole.

Although the curved sloped retaining wall is shown in Fig. 12, it is needless to say that the block of this embodiment can also form a curved vertical retaining wall.

In the present embodiment, the plurality of connection pin insertion holes 12a, 12b, and 12c are arranged diagonally toward the rear outside of the block 1 when viewed in a plan view. However, the present invention is not limited to this, In other words, it is needless to say that a plurality of connection pin insertion holes 12a, 12b and 12c formed on the left and right sides of the upper surface of the block may be disposed diagonally toward the front outside of the block 1.

In the present embodiment, the upper portions of the connection pin insertion holes 12a, 12b, and 12c are integrally and concave. The upper portion of the connection pin insertion hole 12 is formed to be wider toward the upper portion, So that the insertion operation of the pin 3 can be facilitated.

The connection pin 3 inserted into the connection pin insertion hole 12 is made of a metal material having a corrosion resistance or a fiber reinforced resin rod and is formed with a head at the upper end in order to prevent it from falling down, The length of the through hole can reach the middle portion.

The through holes 14 formed between the connecting pin insertion holes 12 are formed symmetrically with respect to the direction of the rear surface 60 and the side surfaces 40 and 50 of the block 1 And the inner front surface 14a is in the form of a plane parallel to the front surface 30 of the block 1, so that the connection pin inserted in the upper block is closely contacted.

4 and the bottom view of FIG. 5, the through hole 14 has a wide upper portion and a relatively narrow lower tapered shape so that the core of the forming mold can be easily detached .

In the present embodiment, reinforcing material insertion grooves 16 opened to the rear surface 60 are formed at a predetermined depth behind the both side through holes 14, and between the both side through holes 14, And the stiffener 2 inserted into the side stiffener insertion grooves 16 is directly connected to the block 1 in a ring shape (U-shape) as shown in Figs. 13 and 14 .

In the block 1 according to the present embodiment, as shown in the drawing, the leading end of the band-shaped fiber reinforcing member 2 of a predetermined length is folded in half width and connected to both ends of the reinforcing member 2, It is also possible that the staple fiber reinforcing material having a long length is continuously connected to the left and right adjacent blocks so as to be in a staggered state.

The reinforcing material insertion groove 16 is opened rearward along the two projections 62 forming the rear surface 60 so that a reinforcing material embedded in the reinforcing material at the rear of the block 1 can be fitted. The reinforcing material 2 used in the example is a band-like fiber reinforcing material which is folded in half width and is inserted into the reinforcing material inserting grooves 16 and 18 of the block 1, so that a sudden bending does not occur and local stress is concentrated on the reinforcing material The stiffener is prevented from being scratched or scratched by the stiffener as compared with the method of connecting the stiffener to the block by the load and the frictional force of the block by inserting the stiffener between the upper and lower blocks like the conventional geogrid reinforcement, It is possible to prevent chemical damage due to long-term contact with the concrete block as a material.

 It is preferable that the depth of the reinforcing material insertion grooves 16 and 18 is formed to a sufficient depth so that the reinforcing material 2 does not protrude above the block upper surface 10 when the reinforcing material 2 is folded in half width If it is formed deeper than necessary, the structural strength of the block may be lowered. Therefore, the width and thickness of the stiffener to be used should be taken into consideration to design the depth and width appropriately.

In the present embodiment, since the reinforcing member insertion grooves 16 and 18 have a deep and wide fitting state of the reinforcing member 2 inside the center of the block 1, the connecting force between the block and the reinforcing member is excellent, The tensile force is not applied to the rear end of the block but applied almost entirely to the block, and the stiffener is also inserted into the large-radius loop state without local bending due to the conventional pin coupling method, In addition, even when a differential settlement of the reinforced soil occurs, it is possible to flexibly fold the reinforcement material into the reinforcement material in a half width, .

The side surfaces (40, 50) are tapered at a predetermined angle from the front surface (30) to the rear side so as to eliminate the interference between adjacent blocks on the left and right sides so that the curved retaining wall can be constructed And the side surfaces 40 and 50 extend in a stepped manner toward the protruding portion 62 forming the rear surface 60.

A recessed depressed portion 64 is formed between the two projecting portions 62 forming the rear surface 60 so that the weight of the block can be reduced and stereoscopic connection with the reinforcing soil can be achieved. That is, since the indentation portion 64 is filled with the reinforcing material or the drainage aggregate, the contact surface between the block and the reinforcing material can be coupled to the wide and deep portion.

15, even when a curved retaining wall is constructed as shown in Fig. 15, the reinforcing member 2 is uniformly distributed in the horizontal direction, and the connection state and the connection strength between the reinforcing member and the individual blocks So that the block and the stiffener are connected to each other not by the frictional force due to the load but by the fitting method so that the connection strength between the block and the stiffener is uniform in the horizontal and vertical directions It is possible to construct a stable reinforced earth retaining wall.

Figs. 16 and 17 show a corner block 1 'according to another embodiment of the present invention, which is basically the same as the standard block 1 of the embodiment, except that the projection on one side of the rear side is removed, The left and right side surfaces are formed so as to be perpendicular to the front surface so that adjacent blocks can be formed at right angles to each other.

To be more specific, the corner block 1 'has a connection pin insertion hole 12 through which a connection pin for interlocking between the upper and lower blocks is inserted, on one side of the upper surface 10, A reinforcing material insertion groove 16 is formed in the rear of the both side through holes 14 and a reinforcing material insertion groove 18 is formed between the both side through holes 14, So that the stiffener 2 can be connected to both the stiffener insertion slots 16 and the intermediate stiffener insertion slots 18 in the form of a loop.

The corner block 1 'of this embodiment includes a top surface 10 and a bottom surface 20 in a generally flat state, a front surface 30 that is split to have a surface texture of natural stone, (50) having a tapered surface at a predetermined angle in the rear direction from the front surface (30) and a rear surface (50) extending from the front surface (30) And has a rear face 60 made up of one extended portion 62 and one indented portion 64.

The corner block 1 'is formed with a non-protruding surface 62a in which the protruding portion is not formed rearward at the rear end of the one side surface 40. The protruding surface 62a is formed at a right corner portion of the civil engineering structure, Is adjacent to the side 50 of the standard block or corner block.

The front face 30 and the side face 40 of the corner block 1 'may be formed in various patterns by a molding frame in addition to the natural stone texture as shown in the drawing.

In this embodiment, as shown in the figure, The side surface 40 is formed on the left side of the front surface 30 rather than on the right side thereof. The side surface 40 is formed as a set, and is formed as an intersection on the left and right sides of the corner portion of the retaining wall as shown in FIG.

Although the protruding rectangular corner portion is shown in FIG. 18, the corner block 1 'according to the present invention can also be formed by vertically crossing the recessed rectangular corner portion.

The standard block 1 is disposed adjacent to the side of the corner block 1 'used at the time of constructing the rectangular core portion, so that a retaining wall having a predetermined length can be constructed.

Fig. 19 shows a state in which a band-shaped fiber reinforcement 2 is installed at a right corner portion of the retaining wall shown in Fig. 18. At the rear of the standard block 1 forming a right angle with the band-like fiber reinforcement 2, And one side of the corner block 1 'is laid on the corner block 1' so as to intersect with the staple fiber reinforcement 2 connected to the standard block 1 at an angle of substantially 45 °, that is, diagonal to the staple fiber reinforcement 2 And the other is buried in the reinforcing soil body in a state of being installed in parallel with the band-shaped fiber reinforcement 2 connected to the one standard type block 1, so that the corner portion of the reinforcing earth retaining wall can be solidly built.
