Description

Slope Structure for Reinforcing Slope

The present invention relates to an inclined reinforcement structure, and more particularly, the front reinforcement of the lattice structure bent in the form of "∠" to fit the inclination angle of the inclined surface on the front surface of the foundation ground by the connecting rod and the rear reinforcement The galvanizing welding wire mesh is interposed between the horizontal rod and the vertical rod forming the front reinforcement body to form the horizontal rod, the vertical rod and the galvanized welding wire mesh by the pressure welding method, thereby carrying and constructability of the grid structure. At the same time, it is possible to more easily carry out compaction of the soil through the inner bottom of the lattice structure, thereby preventing sedimentation phenomenon occurring at the lower inner side of the lattice structure. It prevents the easy installation of vegetation soil and the loss of seeds, which greatly contributes to the early recording of slope. To relate to the slope reinforcing structure.

In addition, the inclined surface reinforcement structure of the present invention is prefabricated by connecting the inclined drainage structure extending along the inclined surface to the inner side of the grid structure, and the horizontal drainage structure extending horizontally from the inclined drainage structure to the rear side of the inclined drainage structure By connecting with each other, it is possible to easily discharge the surface layer of the inclined surface and the permeate and ground water flowing into the inclined surface along with the strength of the inclined surface by each drainage structure, and the lower end of the inclined drainage structure and the rear end of the horizontal drainage structure. The present invention relates to an inclined reinforcement structure in which each drainage structure is more firmly supported by the concrete drainage channel, and at the same time, it is possible to more easily discharge a large amount of infiltration water and groundwater flowing into the slope. .

In general, when some of the slopes of the mountain slopes or hills are damaged by natural disasters such as heavy rains or floods, the damaged slopes are shaved by a certain amount, and soils are filled in the areas to form new slopes. In the case of opening a new lamp, the slope of the mountain slope or hill is cut by a certain amount to flatten the open surface, and the remaining part is formed as a new slope, and it is formed near the river or lake to prevent the flooding of the river and to use the water resources. Old banks and embankments also have slopes due to sediment fill.

When the unstable slope of the fill area or cut area created by cutting or filling up the soil as a new terrain as described above is left uncovered, the soil is easily lost due to various natural causes such as heavy rain or flood. Not only do you have to perform the repair work on the slopes, but also, in severe cases, the inclined surface of the earth can be collapsed, which leads to enormous human life and property damage.Therefore, the surface of the slope is installed by installing a separate protection and reinforcement structure on the slope. Risk factors such as collapse and rockfall from activities should be blocked in advance.

As a conventional slope protection and reinforcement method for stabilizing the inclined surface as described above, a method of fixing the vegetation mat and wire mesh on the inclined surface using an anchor bolt, and then attaching the green soil composition having excellent viscosity through the wire mesh, A method of bending iron bar gratings in which the horizontal bar and the vertical bar are integrally bent in the form of "형태" according to the inclination angle of the inclined surface, and then laminating the iron bar grating on the front side of the inclined surface, and using plastic, steel or The method of connecting various blocks made of concrete in the form of squares or hexagons, the method of drilling holes of a certain depth in the slope using a perforator and grouting by inserting the nail nail and mortar in the holes, The construction method of building a large concrete structure in the form of a retaining wall is known on the front side. There.

Of the conventional slope protection and reinforcement methods as described above, the method using the vegetation mat and wire mesh has the advantage that the greening of grass and wood plants can be achieved to achieve the greening of the inclined surface, but until the complete greening of the inclined surface is completed. Compared with the construction method, there was a disadvantage that the protection strength of the inclined surface was inferior. In the case of the method of connecting blocks of various materials on the surface of the inclined surface, the protection strength of the inclined surface could be improved somewhat compared to the above-described method, but the soil loss in rainy weather Due to this, there was a disadvantage that early recording of slopes was difficult, and in the case of grouting method or concrete retaining wall method, the protection and reinforcement strength of slopes could be improved to a higher level than other methods, but the growth of grass and tree plants on slopes Not only is it not environmentally friendly, but the initial cost of construction is excessive. After you take and the construction of the structure was a downside with steady maintenance it should be parallel.

However, the conventional inclined surface protection method using the iron bar grid reinforces the strength of the inclined surface by the iron bar grid installed on the front side of the inclined surface, and attaches the vegetation soil to the front wall of the iron bar grid to install the vegetation soil. Due to the advantage that greening is also possible, it is widely used as a protection method of the inclined surface, and thus, a conventional inclined surface reinforcement structure using an iron rod grating is disclosed in Japanese Unexamined Patent Publication No. 4-213625 (published on Apr. 1992).

The conventional inclined surface reinforcement structure as described above is bent in the form of "형태" to meet the inclination angle of the horizontal bar and the vertical bar bar to form a front reinforcement and the rear reinforcement, the iron bar lattice formed as described above On the front side of the stacking to fit the height of the slope, the front reinforcement and the rear reinforcement by connecting a plurality of S "hook to reinforce the strength of the iron bar grating, the front reinforcement of the iron bar grate covered the greening sheet The vegetation soil can be mounted to the front of the seat, and the non-woven fabric as a reinforcing fleece is covered on the bottom surface of the rear reinforcement body, that is, the upper surface of the foundation ground, and then the soil is fixed to the rear of the iron bar grid. .

However, the conventional inclined surface reinforcement structure as described above uses a steel bar grid formed integrally with the front reinforcement and the rear reinforcement, so that the load and the volume of the steel bar grid are very large, and thus, many steel bars are transported to the construction site. In addition to the difficulties, the installation of the iron bar grating on the slope at the construction site was also very difficult to solve the problem, and in order to reduce the weight of the iron bar grating when manufacturing the iron bar grating using hollow pipe instead of steel bar grating There was a problem in that the deformation of the front reinforcement of the iron rod lattice bulging out easily during the compaction process of the earth and sand was reduced.

In addition, the lower inner part of the iron bar lattice bent in the form of "∠" in the process of consolidating the soil to the inside of the iron bar lattice can not be firmly compacted using the compaction machine such as a vibrating roller. There was a problem that the sedimentation of sediment on the inner side of the lower part could not be made properly. Therefore, when a certain period of time elapses after reinforcement of the inclined surface using the iron bar grating, the soil is recessed to the lower inner side of the iron bar grating. There was a problem that adversely affects stabilization.

In addition, when the green sheet is covered on the front reinforcement of the iron bar grating, the recording sheet flows easily along the inclined front reinforcement according to the inclination angle of the inclined surface, so that the cumbersome connection of the recording sheet to the front reinforcement is prevented. As well as having to go through the work, there was a problem that the greening sheet is easily torn in the process of connecting the iron bar grid and the greening sheet or in the process of filling the soil to the inside of the iron bar grid.

In particular, the structure used in the conventional slope protection and reinforcement method, including the iron bar grating is intended to reinforce the surface layer of the inclined surface, the slope applied to such slope protection and reinforcement structure is jointed and discontinuous during the construction of each structure Strata often occur, and large quantities of rainwater penetrate into the slopes during rainy weather, and the inflow of groundwater is also increased. The structures used in conventional slope protection and reinforcement methods include There was a problem in that it could not prevent the infiltration and groundwater discharge properly and prevent the delamination and rock oxidation by the infiltration and groundwater, and the groundwater and groundwater repeatedly freeze and thaw. If you go through the erosion of the strata and the oxidation of rocks Before the end was the problem that caused the collapse of the slope.

The present invention has been made to solve the conventional problems as described above, the inclined surface reinforcement structure according to the present invention is the front reinforcement of the grid structure bent in the form of "∠" to meet the inclination angle of the inclined surface in the front surface of the foundation ground Sieves can be installed in a prefabricated manner with the rear reinforcement by connecting rods, and the horizontal bars, longitudinal bars and galvanized welded wire mesh are integrated by means of a pressure welding method by interposing a galvanized welding wire mesh between the horizontal bars and the vertical rods forming the front reinforcement body. As a result, it is possible to improve the transportability and workability of the lattice structure, and at the same time, it is possible to more easily carry out compaction of the soil through the inner bottom of the lattice structure. In addition to the prevention of phenomena, the easy installation of vegetation soil and the loss of seeds by galvanized welded wire mesh It is a technical problem to prevent a significant contribution to early recording of the inclined surface.

In addition, the inclined surface reinforcement structure of the present invention is prefabricated by connecting the inclined drainage structure extending along the inclined surface to the inner side of the grid structure, the horizontal drainage structure extending horizontally from the inclined drainage structure to the rear side of the inclined drainage structure By connecting with each other, it is possible to easily discharge the surface layer of the inclined surface and the permeate and ground water flowing into the inclined surface along with the strength of the inclined surface by each drainage structure, and the lower end of the inclined drainage structure and the rear end of the horizontal drainage structure. Another technical challenge is to install concrete drainages in the building so that each drainage structure can be more firmly supported by the concrete drainages, and at the same time, it is easier to discharge a large amount of infiltration and groundwater flowing into the slope. do.

The present invention for achieving the above technical problem, the horizontal bar and the vertical bar is connected to the lattice form, the lattice structure is installed on the front surface of the foundation ground, and the infiltration water or groundwater installed in the rear of the lattice structure introduced into the inclined surface It consists of a drainage structure for discharging to the outside, the lattice structure is formed of a rear reinforcement placed on the front upper surface of the foundation ground and a front reinforcement bent upward to match the inclination angle of the inclined surface from the rear reinforcement The front reinforcement of the lattice structure is prefabricated and connected by a longitudinal rod tip and a connecting rod of the rear reinforcement protruding upward so that the lower end of the longitudinal rod is inclined to the inclination angle of the inclined surface, the front reinforcement of the lattice structure The galvanized welded wire mesh is inserted between the horizontal bar and the vertical bar so that each horizontal bar and the vertical bar are pressed. It is characterized in that by way integrally formed with galvanized welded wire mesh.

In addition, the inner side of the lattice structure is a support block which is supported by the upper surface of the rear reinforcement to the front end of the body bent in the form of "┛" in accordance with the inclination angle of the inclined surface penetrated between the lower longitudinal rods of the lattice structure, An inclined drainage structure consisting of a straight inclined drainage block connected to the supporting block integrally by a connecting block at an upper end thereof is installed, and the rear of the inclined drainage structure has a straight block whose body is bent in a "∪" shape.

As shown in FIGS. 1 and 2, the inclined surface reinforcement structure according to the present invention includes a lattice structure 10 installed on the front surface of the foundation ground by connecting the horizontal rods 10a and the vertical rods 10b in a grid form. The slanted drainage structure 20 and the horizontal drainage structure 30 are installed in the rear inner side of the grid structure 10 to discharge the infiltration water or the groundwater to the outside, and the horizontal drainage structure ( On the rear side of 30, a concrete drainage passage 37 is formed integrally with the horizontal drainage structure 30.

Among the inclined surface reinforcement structures according to the present invention having the above configuration, the grid structure 10 installed on the front side of the inclined surface and used to reinforce the surface layer of the inclined surface is placed on the front upper surface of the foundation ground, as shown in FIG. 1. The rear reinforcement body 11 and the front reinforcement body 12 which extends upwardly along the inclination angle of the inclined surface from the rear reinforcement body 11, the front reinforcement body 12 is horizontal bar (10a) and vertical When the galvanized welded wire mesh 13 is inserted between the rods 10b, each of the horizontal rods 10a and the vertical rods 10b are integrated with the galvanized welded wire mesh 13 by the spot weiding method. And a lower end portion of the vertical rod 10b is prefabricated by means of the connecting rod 14 and the end of the longitudinal rod 10b of the rear reinforcing body 11 protruding upward to fit the inclination angle of the inclined surface. Is done.

As described above, the front reinforcement body 12 and the rear reinforcement body 11 constituting the lattice structure 10 can be prefabricated by the connecting rod 14, so that the manufacturing operation of the lattice structure 10 can be performed more easily. In addition, the lattice structure 10 may be prevented from being damaged in the process of bending the lattice structure 10 in a "∠" shape to fit the inclination angle of the inclined surface, and the front surface of the lattice structure 10 during transportation. Since the reinforcement body 12 and the rear reinforcement body 11 can be transported in a state in which the volume is minimized, the transportability of the grid structure 10 can also be improved.

In particular, in the process of constructing the lattice structure 10 on the front side of the inclined surface by filling the soil, only the rear reinforcement 11 is firmly positioned on the foundation ground to the upper surface of the rear reinforcement 11. After the soil is first compacted, the front reinforcement 12 may be assembled at the tip of the vertical rod 10b of the rear reinforcement 11, thereby improving the workability of the lattice structure 10. The compaction of the earth and sand on the lower inner side of the lattice structure 10 that is bent in a form may also be achieved using various compaction machines.

As described above, since the front reinforcement body 12 and the rear reinforcement body 11 are assembled to form a grid structure 10, the connecting rod 14 used for the connection has excellent tensile strength and resistance to corrosion. It is preferable to use steel parts, and the connecting rod whose inner diameter is larger than the outer diameter of the vertical rod 10b so that the vertical rod 10b of the front reinforcement 12 and the rear reinforcement 11 can be easily inserted. 14) is preferred.

In addition, the pressure welding method applied to the manufacturing of the front reinforcing body 12 is inserted into the galvanized welding wire mesh 13 between the horizontal bar (10a) and the vertical bar (10b) in the form of a lattice, each horizontal bar (10a) ), The vertical rod 10b and the galvanized welded wire mesh 13 are brought into contact with each other, so that a current flows through a three-stage pressure welder having a constant current MICOM TIMER 201, and thus the horizontal rod 10a, the vertical rod 10b, and the galvanized plate. The front reinforcement body 12 is manufactured to be welded accurately according to the required dimensions and specifications by generating heat of electrical resistance near the melting point at the contact portion of the welded wire mesh 13, and the front reinforcement body 12 manufactured as described above is manufactured. The welding defect rate is almost zero, and forms a strong frame which does not cause warpage or slippage even under prolonged use or various vibrations or shocks.

In particular, the front reinforcing body (12) consisting of a horizontal rod (10a) and a vertical rod (10b) by pressing between the horizontal bar (10a) and the vertical bar (10b) through a galvanized welded wire mesh 13 having excellent corrosion resistance and strength. The supporting strength of the galvanized welded wire mesh 13 is further increased by this, so that the horizontal reinforcing rods 10a and the vertical rods 10b are hollow pipes, so that even when the front reinforcement body 12 is manufactured with a relatively light load, When the compaction construction of the grid structure 10, the front reinforcement 12 of the grid structure 10 is not deformed, such as a bulge bulge by the earth pressure, as well as the cumbersome work of covering the green sheet on the front reinforcement (12) Even without going through the galvanized welded wire net 13, it is possible to greatly contribute to the premature greening of the slope while preventing the easy installation of the vegetation soil and the loss of seeds contained in the vegetation soil.

In order to more easily mount the vegetation soil through the front reinforcing body 12 as described above, the horizontal bar (10a) is located in front of the galvanized welding wire mesh 13 and the vertical rod (10b) is galvanized welding wire mesh (13) It is preferable to be located at the rear of the, because the vegetation soil which is mounted in front of the front reinforcement body 12 when the longitudinal rod (10b) is located in front of the galvanized welded wire mesh 13 is the front reinforcement ( While there is a possibility to flow along the inclination angle of 12), when the horizontal bar (10a) is located in front of the galvanized welded wire mesh 13, the vegetation soil is mounted in front of the front reinforcement (12) horizontal bar (10a) Because it is firmly supported between the vegetation soil does not flow along the front reinforcement (12) even in the rain.

The lattice structure 10 of the present invention having the above structure is constructed on the front side of the inclined surface, and at the same time, the drain pipe and the "S" type bundle pipe (playground, park, golf course or residential land, etc.) Widely used for culvert drainage or for backwater treatment of structures or for culvert drainage such as roads and tunnels, in which plastic plates are bent in S-shape to form pipes), even when buried as drainage structures. It is possible to achieve the purpose of discharging the infiltration water and groundwater flowing into the interior.

However, it is preferable to install the drainage structure of the present invention as shown in FIG. 2 on the rear side of the grid structure 10 so as to more reliably achieve the purpose of drainage together with the strength reinforcement inside the inclined surface. In FIG. 2, the galvanized welded wire net 13 installed in the front reinforcement 12 of the grid structure 10 is omitted in order to more clearly show the coupling relationship of the drainage structure.

As shown in FIG. 2, the drainage structure forming the reinforcement structure 1 of the present invention together with the grid structure 10 as described above is an inclined drainage structure installed along the inclined surface at the rear side of the grid structure 10 ( 20) and a horizontal drainage structure 30 extending horizontally from the inclined drainage structure 20 to the rear, the rear end of the horizontal drainage structure 30 is integrally connected with the horizontal drainage structure 30 The concrete drainage channel 37 is formed.

The inclined drainage structure 20 has a front end portion of the body which is bent in a “┛” shape according to the inclination angle of the inclined surface and penetrates between the lower vertical rods 10b of the lattice structure 10 so as to be aligned in the upper surface of the rear reinforcement 11. It consists of a plurality of support blocks 21 and the inclined drain block 26 of the straight line connected integrally with the support block 21 by the connection block 24 at the upper end of the support block 21, Each end side of the support block 21 and the inclined drainage block 26, the fitting projections 23, 27 are simply projected, and the fitting projections 23, 27 inside both sides of the connection block 24 The insertion groove 25 to be inserted is simply formed so that each block can be assembled integrally.

In addition, inside the body of each of the blocks 21, 24, 26, the drainage passage 22 is formed through the body, so as to assemble the respective blocks 21, 24, 26 of the inclined surface It is possible to form a drainage path along the front side, the body of each block (21) (24) and (26) with its center part concave inwardly so that it can be reliably buried with the soil during compaction of soil. It is formed, each block 21, 24, 26 by passing a fastening hole through the connection portion of each block 21, 24, 26 to assemble the inclined drainage structure 20 more firmly Can be fastened as a bolt and a nut.

The inclined drainage structure 20 having the above configuration reinforces the surface layer of the inclined surface together with the lattice structure 10 and simultaneously discharges the infiltration water flowing into the surface layer of the inclined surface through the top of the inclined surface during rainy weather to the front side of the inclined surface. As a function of promoting stable support of the inclined surface by the structure 10 and preventing surface activity of the inclined surface by the infiltration water, each block 21, 24 and 26 forming the inclined drainage structure 20 is made of plastic. Manufacturing by injection molding using a material is preferable in terms of weight reduction of parts and manufacturing cost.

In addition, the horizontal drainage structure 30 has a T-shaped block 32 and a cross-shaped block 33 and a cross-shaped block 31 having a body having the same shape as the straight block 31 whose body is bent in a “∪” shape to form a drainage path. It is made of a configuration that is connected in the horizontal and vertical direction by the "a" shaped closing block 34, as shown in Figure 2 enlarged, both ends of the straight block 31, the connecting end 31a is simply projected, cross-shaped On each end side of the block 33, the connecting groove 33a into which the connecting end portion 31a is inserted is simply formed inward, and although not shown, the T-shaped block 32 and the "a" shaped closing block 34 In addition, a connection groove of the same type into which the connection end portion 31a of the straight block 31 is inserted is formed inside the end of each of the blocks 32 and 34.

The horizontal drainage structure 30 having the above configuration is installed at the rear side of the grid structure 10 and the sloped drainage structure 20 to reinforce the strength of the inclined surface and to flow into the inclined surface through the surface layer of the inclined surface. As a function of discharging the infiltration water and the ground water eluted to the inside of the inclined surface to the outside of the inclined surface, for this purpose, the front end of the straight block 31 extending in front of the horizontal drainage structure 30, that is, the connecting end 31a ) Is inserted into the inclined drainage block 26 through the insertion hole 28 formed at the rear side of the inclined drainage block 26, and the inside of the tip of the straight block 31 connected to the inclined drainage block 26. In order to block the inflow of soil to the horizontal drainage structure 30, a blocking plate 35 having a drainage net 36 is inserted.

Each block 31, 32, 33, 34 of the horizontal drainage structure 30 is also preferably manufactured by injection molding using a plastic material in terms of weight reduction of parts and reduction of manufacturing cost. In order to assemble the horizontal drainage structure 30 more firmly, each block 31, 32, 33 is formed by passing a fastening hole through the connection portion of each block 31, 32, 33, 34 ( 34) may be tightened as a bolt and a nut.

Finally, at the rear end of the horizontal drainage structure 30, the concrete drainage passage 37 integrally installed with the horizontal drainage structure 30 serves to support the horizontal drainage structure 30 more firmly and at the same time inclined surfaces. In order to more effectively discharge a large amount of permeated water and groundwater flowing into the interior of the construction site, using the formwork in the concrete drainage path 37 can be cast integrally with the horizontal drainage structure 30, other than the construction site The concrete drainage system 37 cured in advance at the construction site may be prefabricated with the horizontal drainage structure 30 at the construction site. In the latter case, the linear block 31 of the horizontal drainage structure 30 may be inserted. The ball should be formed in advance on one side of the concrete drainage channel 37.

In addition, in addition to installing the concrete drainage channel 37 on the rear side of the horizontal drainage structure 30, the support block 21 in front of the inclined drainage structure 20, that is, the bottom of the inclined surface of the support block ( 21 may be provided with a concrete drainage channel 37 (shown in FIG. 4 to be described later), and the concrete drainage channel 37 installed as described above may be selectively installed on a slope portion where a large amount of infiltration water and groundwater are generated. It is preferable to apply in the aspect of reducing the overall construction cost of the slope reinforcement structure (1).

Referring to Figures 3 and 4 will be described in more detail with reference to Figs.

First, the site to apply the slope reinforcement structure (1) according to the present invention on-site survey, the ground and soil on the slope to which the problem is exposed, such as a place where the ground is weakened by rainy weather, or to create a new road or railway After the investigation is completed, the slope slope of the reinforcement structure 1 to be constructed and the appropriate specifications of various equipments are determined based on the data surveyed as described above, thereby completing the design for the construction of the reinforcement structure 1.

When the design for the construction of the reinforcing structure (1) is completed as described above, the inclined surface is cut out by a predetermined range using an excavator, etc., and the excavated soil is piled up on one side of the work site for reclaiming, and the inclined surface is cut off. The bottom layer of is to be flattened and compacted using a vibrating roller or various compacting machines to form the foundation ground 2 on which the reinforcing structure 1 of the present invention is to be installed.

After the foundation ground 2 is constructed as described above, the grid structure 10 is installed on the front surface of the constructed foundation ground 2, but the strength of the inclined surface before the grid structure 10 is installed. For reinforcement, it is preferable to cover the geogrid or long fiber nonwoven fabric throughout the base ground (2), and thus the rear surface of the grid structure (10) on the front upper surface of the base ground (2) covered with the geogrid or long fiber nonwoven fabric The reinforcement 11 is placed together with the support block 21 of the inclined drainage structure 20, and then the back reinforcement 11 is firmly fixed on the foundation ground by using a non-transmission material or a pile. At the same time, the support block 21 is firmly bound to the rear reinforcement 11 using a wire or the like.

At the same time, in an area where a large amount of infiltration water may flow through the front side of the inclined surface, the concrete drainage channel 37 is selectively provided on the front surface of the support block 21 formed integrally with the rear reinforcement body 11. It can be poured and constructed, as shown in Figure 4 may be installed so that the front end of the support block 21 is placed on one side of the concrete drainage channel 37, the front end of the support block 21 is a concrete drainage (39) It may be installed to penetrate one side of the).

As described above, the rear reinforcement body 11 and the support block 21 are firmly fixed to the front upper surface of the foundation ground 2, and then the earth is primarily deposited on the upper surface of the rear reinforcement body 11. A compaction machine such as a vibrating roller firmly compacts the soil deposited to the front end of the rear reinforcement 11 corresponding to the lower inner portion of the grid structure 10, and then connects the front reinforcement 12 of the grid structure 10 to the connecting rod. By connecting to the distal end of the longitudinal rod (10b) protruding forward of the rear reinforcement (11) by the (14) it is possible to assemble the grid structure 10 on the foundation ground (2), if necessary, The front reinforcement body 12 and the rear reinforcement body 11 by connecting a plurality of S "hook 15 may further reinforce the strength of the grid structure (10).

After the lattice structure 10 is completely assembled on the base ground 2 as described above, the soil is secondaryly deposited inside the lattice structure 10 to compact the soil by the height of the support block 21. The earth pressure generated during the compaction construction process of the earth and sand is firmly supported by the front reinforcement body 12 having the galvanized welded wire mesh 13 to deform the grid structure 10 due to the earth pressure. It is possible to prevent, when the compaction of the soil to the height of the support block 21 is completed, while connecting the inclined drain block 26 to the upper end of the support block 21 integrally by the joint block 24 and at the same time lattice structure The front reinforcing body 12 of the (10) is connected to the front reinforcing body 12 of the same shape by the connecting rod (14).

After the assembly of the lattice structure 10 and the inclined drainage structure 20 is completed as described above, the earth and sand are refilled to the inside of the front reinforcement 12 having the galvanized welded wire net 13 to incline the drainage block ( The soil is compacted by the height of the insertion hole 28 formed in the 26. Since the soil compaction in this step forms the ground for the installation of the horizontal drainage structure 30, the compacted soil layer is formed flat. .

When the compaction construction of the earth and sand for the installation of the horizontal drainage structure 30 is completed as described above, the horizontal drainage structure 30 is installed on the top surface of the fill layer. 35 is inserted into the front end of the straight block 31 so that the connecting end 31a is inserted through the insertion hole 28 of each inclined drain block 26, and then the The T-shaped block 32 and the cross-shaped block 33 at the rear end are used to sequentially connect the straight block 31 in the horizontal and vertical directions, and at the rear end thereof, the T-shaped block 32 and the "a" shape. By connecting each of the straight block 31 using the finishing block 34 to assemble the horizontal drainage structure 30 of the grid form.

When assembling the horizontal drainage structure 30 as described above, when a large amount of infiltration water and groundwater are expected to flow into the inclined surface where the reinforcement structure 1 of the present invention is constructed, the rear end of the horizontal drainage structure 30 is formed. The concrete drainage channel 37 is selectively placed and constructed in this way, and when the concrete drainage path 37 is to be installed in this way, the concrete drainage path 37 is installed during the soil compaction for the installation of the horizontal drainage structure 30. A free space should be formed in the rear side in advance.

After the installation of the horizontal drainage structure 30 and the concrete drainage passage 37 is completed as described above, after plowing the soil to the height of the horizontal drainage structure 30 and the concrete drainage passage 37, the horizontal drainage structure 30 is formed. Filling the aggregate (4) in the interior of the drainage channel and the concrete drainage channel 37, the earth drainage into the interior of each drainage on the upper surface of the horizontal drainage structure 30 and the concrete drainage channel 37 filled with the aggregate (4) The reinforcing structure 1 according to the present invention can be constructed on the inclined surface by covering the sheet 3 to prevent the drainage path from being blocked and finally compacting the soil to the top of the inclined drain block 26. It will be possible.

What has been described above is a process of forming the basic reinforcement structure layer using the reinforcement structure 1 of the present invention, as shown in Figures 3 and 4, the front reinforcement 12 of the grid structure 10 The connecting rod 14 can be continuously extended along the inclined surface, the inclined drain block 26 of the inclined drainage structure 20 can also be continuously extended along the inclined surface by the joint block 24, but the height of the inclined surface Since the support strength of the inclined surface by the front reinforcing body 12 is lowered as the higher the maximum height for forming one reinforcing structure layer on the inclined surface using the reinforcing structure (1) of the present invention is 2m or less (45 ~ 60 ° It corresponds to the height of connecting two or three front reinforcement on the inclined surface of the angle).

Therefore, when the height of the inclined surface on which the reinforcing structure 1 of the present invention is to be installed becomes 2 m or more, as shown in FIG. 4, the total height of the inclined surface is divided by about 2 m units and the primary reinforcing structure at the lowermost end. After forming the layer, it is preferable to sequentially form the reinforcing structure layer along the inclined surface in such a manner that the secondary reinforcing structure layer is formed again on the upper side of the reinforcing structure layer.

In addition, in order to make the surface layer strength reinforcement of the inclined surface more firmly, the lattice structure 10 consisting of one front reinforcement body 12 and one rear reinforcement body 11 may be included in two reinforcing structure layers. Four or more laminations may be provided. In this case, it is preferable to sequentially fill the soil based on the lamination height of the lattice structure 10, and the lower lattice structure 10 and the upper lattice structure 10 are " It is preferable to connect integrally using an S "type hook 15 or other similar connecting means, and the inclined drainage block 26 of the inclined drainage structure 20 is a horizontal rod 10a of the rear reinforcement 11. It is preferable to allow the inclined drainage structure 20 to be more firmly connected to each lattice structure 10 by penetrating between the and vertical rods 10b.

As described above, when the inclined surface reinforcement structure 1 according to the present invention is laminated in a sloped manner, the transportability and workability of the lattice structure 10 by the lattice structure 10 having a prefabricated structure as described above. Not only is it greatly improved, but the front reinforcement body 12 in which the galvanized welded wire mesh 13 is integrally press-bonded between the horizontal rod 10a and the vertical rod 10b firmly secures the earth pressure generated when the soil is compacted. By supporting it, it is possible to prevent deformation of the grid structure (10) generated during the construction of the reinforcing structure layer.

In addition, when the soil is compacted into the lattice structure 10, the soil may be firmly compacted to the lower inner side of the lattice structure 10 that is bent in a "∠" shape using various compaction machines such as a vibrating roller. This prevents the sedimentation of soil through the inner bottom of the lattice structure 10 in advance, thereby protecting the inclined surface more stably, as well as the vegetation soil toward the front reinforcement 12 constructed along the inclined surface. When mounting the vegetation soil is firmly attached between the horizontal bar (10a) and the galvanized welded wire mesh 13 of the front reinforcement (12) to prevent the loss of vegetation soil and seeds contained in it even in rainy weather In addition, it can contribute greatly to early recording of slopes.

Further, the inclined drainage structure 20 installed at the rear of the lattice structure 10 not only reinforces the surface layer strength of the inclined surface together with the lattice structure 10, but also flows into the surface layer of the inclined surface through the upper end of the inclined surface in rainy weather. The infiltration water to be smoothly drained to the lower front side of the inclined surface by the concrete drainage passage 37 connected to the inclined drainage structure 20 and the supporting block 21, thereby preventing the surface activity of the inclined surface by the infiltration water. It is possible to support more stably.

In addition, the groundwater eluted into the interior of the inclined surface, including the infiltration water which the inclined drainage structure 20 cannot process, is filled with aggregate 4 therein and the horizontal drainage structure having the sheet 3 covered on the upper surface thereof ( 30) and the horizontal drainage structure (30) and concrete drainage channel (37) at the same time to prevent the erosion of the rocks and the erosion of the rock due to the infiltration or groundwater as it flows into the concrete drainage channel 37 and discharged to the outside of the inclined surface. Compacted together with the soil is to improve the support strength to the inside of the inclined surface to be able to stabilize the slope almost permanently.

In particular, in the process of constructing the slope reinforcing structure (1) according to the present invention, instead of compacting general soils, mixed soils or cements mixed with soil and cement at a predetermined ratio are added as a pH buffer and a fertilizer. Reinforced pressure retaining wall method using a mixed soil in which the cement-based hardener (trade name: Soycrete HS-200) is mixed with earth and sand at a predetermined ratio {aka, Soil Castle When the method is applied, the premature greening of the slope and the slope of the slope due to the increase of coking force of the soil layer by the cement component, the nutrient supply of the grass and wood plants by the slow fertilizer component, and the soil action of the acid soil by the pH buffer It will be able to contribute much more to stabilization.

As described above, the sloped reinforcement structure according to the present invention can be prefabricated with the rear reinforcement by the connecting rod to the front reinforcement of the grid structure bent in the form of "∠" to match the inclination angle of the inclined surface in the front surface of the foundation ground. The galvanizing welding wire mesh is interposed between the horizontal bar and the vertical bar forming the front reinforcement body to form the horizontal bar, the vertical bar and the galvanizing welding wire net by the pressure welding method, thereby improving the transportability and workability of the grid structure. It is effective to prevent the sedimentation of earth and sand occurring in the bottom of the lattice structure by making the compaction construction of the soil through the inside of the bottom of the lattice structure more easily, and galvanized welding Easy installation of vegetation soil by wire mesh and prevention of loss of seeds during rainy season or rainy weather Which it would have the effect that you can contribute.

In addition, the inclined surface reinforcement structure of the present invention is prefabricated by connecting the inclined drainage structure extending along the inclined surface to the inner side of the grid structure, the horizontal drainage structure extending horizontally from the inclined drainage structure to the rear side of the inclined drainage structure In addition, it is possible to easily discharge the surface layer of the inclined surface and the infiltration water and groundwater flowing into the inclined surface with the strength of the inclined surface by each drainage structure, and the lower part of the inclined drainage structure and the horizontal drainage structure. By installing a concrete drainage channel at the rear end, each drainage structure can be more firmly supported by the concrete drainage channel, and at the same time, it is easier to discharge a large amount of infiltration water and groundwater flowing into the slope. To achieve stabilization It is.
