It is about.

Description of the Related Art Convex reinforcement retaining wall and panel type retaining wall, and a description of a reinforcing soil retaining wall of a block-and-panel manner and a method of constructing the same are already known in various ways.

On the other hand, the existing block-assembled reinforcement earth retaining wall has a small block itself and the worker had to lift it up one by one to build it individually, so that the progress of work is rapidly progressed due to the weight of physical fatigue. If the retaining wall had to be built in a short period of time, a large amount of manpower had to be invested, resulting in additional problems caused by the burden of labor costs and the mobilization of many manpower.

In addition, the panel assembly retaining wall is constructed using equipment, so the physical burden on the worker is small and the work proceeds quickly.However, due to the structure of the panel, the retaining wall itself is not compatible with the surrounding natural environment. There was a disadvantage.

In order to solve the disadvantages of the conventional block prefabricated earth retaining wall and panel prefabricated earth retaining wall and to utilize only the advantages of each other, the present applicant is to construct a prefabricated retaining earth retaining wall and the retaining wall formed by vertically constructing a block of a relatively large standard. The block used and its construction method have already been patented as Patent Application No. 2004-37835, Patent Application No. 2004-65998, Patent Application No. 2004-81576, Patent Application No. 2004-89152 and Patent Application No. 2005-4044. The invention is a further complement to these elective drafts.

The purpose of the present invention is to firstly be able to build using equipment to prevent various damages caused by hand and at the same time to be able to build quickly, and secondly, the crack of the block due to the horizontal displacement of the block during the floating settlement of the ground (shear) And third, it is possible to prevent the breakage, and third, when connecting the retaining wall and the reinforcement can be connected directly to the end of the reinforcement to the block without using a separate subsidiary material, such as anchors, the end of the reinforcement is not exposed to the outside without loosening 4th, 1st stacking, 2nd stacking, multistage stacking, and straight-line construction are possible, so it can be constructed in various patterns. To provide a retaining wall construction block that can be partially renovated without digging.

In order to achieve the above object, the present invention includes a front surface and a rear surface in contact with a reinforcement soil to form a surface of a retaining wall; Left and right side surfaces of which concave-convex coupling portions are respectively formed for concave-convex coupling between adjacent blocks; An upper surface on which the reinforcing member or the reinforcing member insertion groove into which the anchor for connecting the reinforcing member is fitted is formed in the front-rear direction; In the retaining wall building block having a lower surface corresponding to the upper surface, the connecting pin insertion hole for fastening the connecting pins between the upper and lower blocks on the left and right sides of the upper and lower surfaces penetrates up and down. In the inner side of the block, two through holes spaced apart from the left and right are formed to penetrate from the upper surface to the lower surface. The through holes are formed at the positions where the connecting pins are inserted into the connecting pin insertion holes of the upper block when the block is stacked. At the rear of the through hole, a reinforcement insertion groove is formed to directly catch the distal end of the reinforcement. The partition wall between the two through holes has a reinforcement insertion groove through which the middle portion of the reinforcement is inserted so that the reinforcement is connected backward through the reinforcement insertion grooves at both sides. Provide formed blocks.

In the present invention, the left and right through-holes have a partition wall formed between the two through-holes in order to reduce the weight of the block but to maximize the structural strength of the block itself, and connecting pin insertion holes formed at the outside of the through-holes on both sides. Silver is made of a long hole to have a long radius in the left and right direction of the block to enable the coupling of the connecting pin even if the block is built up and down straight or curved, the upper block of the upper block located relatively The connecting pin inserted into the connecting pin insertion hole is to be caught by the rear of the through hole of the lower block located at the lower part.

In the present invention, the inner and left and right outer sides of the upper and lower blocks of the block are built up and down alternately, so that the shear force is concentrated on the middle part of the block during floating settling of the ground, so that the lower sides of the cross alternately constructed on the upper block By forming the groove for absorbing external force to be able to incline to absorb the horizontal displacement of the block, it is possible to prevent the middle portion of the block from being sheared by the shear force or to damage the lower edge of the upper block (right corner) do.

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

1 to 4 show the retaining wall construction block according to the present invention, the block of the present invention and the front surface 10 and the back surface 20 in contact with the reinforced soil body to form the surface of the retaining wall; Left and right sides 30 and 30 'having corresponding concave-convex coupling portions 32 and 32' respectively formed for concave-convex coupling between adjacent blocks; An upper surface 40 having a reinforcing member or a reinforcing member insertion groove 44 into which an anchor for connecting the reinforcing member is fitted in a front and rear direction; And a lower surface 50 corresponding to the upper surface 40, and a connection pin insertion hole h for fastening the connection pins P between upper and lower blocks on the left and right sides of the upper and lower surfaces 40 and 50. In the retaining wall construction block penetrating up and down, two through holes 60 spaced left and right by a partition wall 62 penetrate from the upper surface 40 to the lower surface 50 inside the block. The through hole 60 is formed at a position at which the connecting pin P fitted into the connecting pin insertion hole h of the upper block is inserted at the time of stacking of the block, and the rear side of the through hole 60 is a reinforcing material 80. Reinforcement insert groove 44 is directly caught the front end of the reinforcement is formed, the reinforcement member (80) is connected to the rear wall through the reinforcement insert grooves 44 on both sides in the partition wall 62 between the two through holes (60). Reinforcing member insertion groove 44 'passing through the middle portion of the 80 is formed.

In the present invention, the front face 10 of the block protrudes in a rectangular shape, and the protruded front face 10 is formed to have a natural stone texture by split processing, and the receding surfaces 12 and 12 'are formed in a curved shape. The recesses 12 and 12 'are provided with grooves 12a and 12a' extending vertically.

In the present invention, the connecting pin insertion holes (h) formed at the left and right sides of the upper surface 40 are generally positioned slightly ahead of the front and rear width centers of the blocks so as to facilitate the coupling between blocks that are staggered up and down. It is composed of a long hole having a long radius in the left and right directions of the block. Even though the coupling by the connecting pins between the blocks adjacent to the left and right does not form a straight line, it can be mutually coupled at a certain angle. It becomes possible.

As shown in the cross-sectional view of FIG. 8, the connecting pin insertion hole h has a tapered portion h3 formed of an inclined surface between the wide expansion portion h1 of the upper portion and the reduced portion h2 of the lower portion thereof. (P) is easy to insert, the flow of the connecting pin (P) is prevented, the flow is small in the front and rear direction between the upper and lower blocks to prevent the rolling and fall in the forward direction, and the fluidity in the left and right directions This cursor becomes largely resistant to inequality.

In the present invention, the connecting pin P inserted into the connecting pin insertion hole h is located at the rear of the through hole 60 of the lower block B1, as can be seen in the cross-sectional view of FIG. 8, and the lower block B1. Fiber reinforcement 80 is inserted into the reinforcing material insertion groove (44, 44 ') of the) is located in front of the connecting pin (P) located in the through hole 60 of the lower block (B1), so the fiber reinforcement (80) is the lower block It is to be connected to the connecting pin (P) fitted to the upper block (B2) together with the reinforcing material insertion grooves (44, 44 ') of (B1) to construct the reinforcement 80 without connecting each block of each layer It is possible to minimize the consumption of fiber reinforcement within the design allowance.

In the block of the present invention, the left and right reinforcement insert grooves 44 are formed toward the front side at the rear surface 20 of the block, and are formed to be curved toward the center of the block while contacting the through-hole 60 inside the block. The reinforcing material insertion grooves 44 'formed at the partition wall 62 communicate with each other by the reinforcing material insertion grooves 44 in a "∪" shape, and the front end portion of the reinforcing material 80 is inserted into the folded state at half width. In the present invention, since the reinforcement 80 inserted in the block does not open and maintains the folded state, the loosening of the reinforcement does not occur, as well as the reinforcement is not exposed to the upper or front side of the block. It will not interfere.

In addition, the left and right outer and inner sides of the block upper surface 40 has external force absorbing grooves 46, 48, and 48 'having a step lower than the upper surface 40, and the external force absorbing grooves 46, 48, 48 ') prevents the shear force applied to the upper block in the middle part of the block, which is the intersecting position between blocks when the retaining wall is constructed after the block of the present invention is constructed up and down alternately. This is to prevent the right corner of the breakage.

In addition, the external force absorbing groove 46 inside the upper surface 40 is open to the rear surface 20 side of the retaining wall, so that the lever is pressed into the external force absorbing groove 46 which is a gap formed between the upper and lower blocks when the block is constructed. Or push down to finely position the upper block.

Retreating surfaces 22 and 22 'are formed on both sides of the rear surface 20 of the block, and the receding surfaces 22 and 22' are symmetrical with the receding surfaces 12 and 12 'of the front surface 10. If the block of the present invention is formed from the top to form a typical boat (Boat) that narrows the bow and stern.

In addition, the front surface 10 of the block is formed in a protruding shape in a rectangular shape, at least a part is cut in a split method so as to have a natural stone pattern, it can give an atmosphere as if the completed retaining wall is constructed of natural stone after construction. By doing so, it is possible to solve the gritty feeling in the retaining wall of the concrete.

Hereinafter, a process of constructing the retaining wall using the block having the above-described configuration will be described.

5 to 8 illustrate a retaining wall in which a block of the present invention is constructed in a single-stage stacking manner, and the first-stage stacked construction shown in FIGS. 5 to 8 is commonly used in a block retaining wall. , The reinforcement embedded in the reinforcement soil together with the block is a relatively narrow width (about 40 ~ 50mm) band-shaped fiber reinforcement, which is the band-shaped fiber reinforcement in the applicant's patent application 2004-29493 and patent application 2004-111929 The specific form and connection method to the block is described, which is unlike the conventional band-shaped fiber reinforcement, which can be directly connected to the block without a separate anchor to build the retaining wall, strip-shaped fiber reinforcement (80) As shown in the figure is inserted through the reinforcement insert grooves 44, 44 'formed on the upper surface of the block and extends both ends of the fiber reinforcement 80 to the rear of the block to the rear on the reinforcement soil body After pendent ssateumyeon it will be switching back to the block above it.

The reinforcing material 80 may be continuously connected in a zigzag manner as shown in the figure or individually connected to each block (B).

On the other hand, between the adjacent blocks (B) to the left and right adjacent to the non-woven drain filter 100 is installed in the rear of the overlapped portion of the block to prevent the reinforcement soil 70, which is the backfilling soil is exposed to the front of the retaining wall only water retaining wall Allow drainage to the front of the tank.

The block according to the present invention can be constructed not only a straight retaining wall as shown in Figure 5 to 8 but also a curved retaining wall having any curvature radius.

9 to 12 show the retaining wall being constructed in a two-stage stacking manner according to the present invention, and the retaining wall shown in FIGS. 9 to 12 is integrated with a connecting pin (P) by vertically overlapping two blocks. It is transported as a unitized block (U) as much as possible, and when constructing the retaining wall, it can be lifted and constructed at the same time by using equipment such as a crane. Uniting it into a connection pin (P); Second, the first construction step of lifting the unitized block (U) at once and built on the concrete foundation (C); Third, the reinforcement soil 70 is installed on the rear of the primary unitized block U, and the reinforcement 80 is connected to the primary structured block U, and the reinforcement soil 70 is laid on the reinforcement soil 70. Compacting 70; Fifth, vertically stacking at least two or more unit blocks and unitizing them with connecting pins (P); Sixth, a second construction step of constructing the second unit united block (U) to the left, right to cross on the first constructed unitized block (U); Seventh, the reinforcement soil 70 is installed on the rear of the secondary structured block U, and the reinforcement body 80 is connected to the secondary structured block U to lay on the reinforcement soil 70 and reinforcement soil 70 ), And the process after the secondary construction step may be repeated the same process from the secondary construction step according to the height of the retaining wall.

Also in the construction method shown in Figures 9 to 12, the non-woven drain filter 100 between the adjacent unitized block (U) to the left and right is installed in the rear of the overlapped portion of the block reinforcement soil body 70 ) Will not be exposed to the front of the retaining wall and only water can be drained to the front of the retaining wall.

In the construction method shown in FIGS. 9 to 12, the coupling structure of the connection pin and the installation structure of the reinforcement are the same as those described in the construction method shown in FIGS. 5 to 8, and thus a detailed description thereof will be omitted.

13 and 14 show the retaining wall being constructed in a tapered construction method as a block of the present invention, and the unitized block U in the 1st and 2nd construction steps as in the retaining wall shown in FIGS. 9 to 12. For example, four unit blocks are used for the first construction, three for the second construction, two for the third construction, or one for the first and second construction. In case of 5, 3 and 4th construction, the construction can be done in the same way as 4, and in addition, the load received by the retaining wall block itself by gradually reducing the height of the unitized block U in each construction stage. It is to effectively prevent the middle portion of the block is easily broken toward the bottom of the retaining wall with respect to the shear force received when the block is built up and down alternately with respect to.

As the retaining wall shown in FIG. 13 increases in number toward the lower end, the number of blocks unitized increases, so the number of overlapping blocks increases with respect to the shear force due to the load that the block itself receives. It is possible to prevent breakage.

In the construction method illustrated in FIG. 13, the coupling structure of the connection pin and the installation structure of the reinforcement are the same as those described in the construction method illustrated in FIGS. 5 to 8, and thus, a detailed description thereof will be omitted.

15 and 16 are views of the retaining wall being constructed in a straight-shaft manner as a block of the present invention, and FIG. 17 is a front perspective view of the retaining wall showing a partial renovation state of the retaining wall shown in FIG. 15.

15 and 16 does not cause interference between adjacent blocks to the left and right during uneven settlement of the ground, so that the front end of the block or the wall of the retaining wall are not generated, and the retaining wall is not formed. When a part is broken by an external force, as shown in FIG. 17, only the upper blocks B4 in the row in which the damaged block B3 is located are sequentially lifted from the top, and then the broken block B3 is removed and a new one is removed. It is possible to stack them in order, and in the case of renovation, adjacent blocks and rear reinforcement soils can be worked without touching at all, thereby minimizing the work space and cost, workforce and working time required for renovation.

15 and 16, the connecting pin P is inserted through the connecting pin insertion hole h between the upper and lower blocks, which is different from the above-described forming methods.

As described above, the present invention uses a large block having a larger width on the left and right sides than the existing block, and thus, by using the equipment instead of the manual construction, the physical burden on the worker can be greatly reduced, and various patterns of retaining wall When connecting the distal end of the reinforcement, the distal end of the reinforcement is not exposed to the outside or the length of the reinforcement is kept in the folded state in half width, which does not cause the retaining wall due to the loosening of the reinforcement. It is possible to build a high quality retaining wall, and in the case of straight building, it is very resistant to uneven settlement of the ground, and has a useful effect such as easy partial renovation without digging out adjacent blocks and rear reinforced soil.
