Description

Technical Field [0001] The present invention relates to a hydraulic anchor pressure plate and a construction method thereof,

The present invention relates to an anchor pressure plate and an installation method thereof for preventing slope failure and slope stability by reinforcing the slope surface by applying a pressing force to the slope surface by fixedly fixing the end portion of an anchor to be installed in the ground Specifically, by having a cross shape, it is possible to efficiently transmit the tensile force of the anchor to the slope, and by using the steel beam having the upper flange, it is possible to obtain a large rigidity against the flexural load caused by the tension of the anchor And it is easy to carry and handle through light weight, and it is easy to use the standardized beam of I-shaped cross section, so it is cheap in production cost, has vegetable and environment friendly characteristics, To ensure that the installed anchors are arranged in a straight line without being bent or bent. It relates to anchor the pressure plate and a construction method that can be provided.

In order to prevent collapse of the slope, an anchor is installed in the ground of the slope, and an anchor is tensed to introduce a tension force. An anchor pressure plate for transmitting the anchor to the slope under the tension of the anchor is installed on the slope. The anchors, which are intruded into the ground and into which the tension is introduced, are fixed to the anchor hydraulic plates through the anchor hydraulic plates at their outer ends. The anchor hydraulic plate is strongly pressed in the sloping direction by the tension of the anchor, thereby reinforcing and stabilizing the sloping surface.

 The conventional anchor pressure plate used for fixation of the anchor and reinforcement of the slope surface is made of a reinforced concrete member so as to have a cross shape. Such a conventional reinforcing concrete anchor pressure plate is disclosed in Korean Utility Model Application No. 20- 0457690 and the like. However, since the anchor pressure plate of this prior art is made of a reinforced concrete member, the weight of each anchor is very heavy, about 2 tons. Therefore, it is very difficult to transport and handle, and the anchor hydraulic plate can not be transported and installed without using large equipment such as large trucks and large cranes. For this reason, it may not be possible to lift the anchor hydraulic plate and install it on the slope surface at a narrow site where large equipment can not enter.

In particular, since the conventional anchor pressure plate made of a reinforced concrete member is already manufactured in a cross shape from a factory, it is disadvantageous in that it is very inconvenient because of its shape.

In addition, in order to manufacture a conventional anchor hydraulic pressure plate as a reinforced concrete member, a large formwork is required and a cross-shaped formwork is required. Therefore, it takes a lot of cost to manufacture a formwork and a large space is required for manufacturing. In addition, there is a disadvantage that very complicated reinforcement work is required which requires reinforcement in a cross shape. In addition, in the case of a conventional cross-shaped anchor hydraulic plate manufactured only from a reinforced concrete member, there is a limitation in that the slope provided with the conventional anchor hydraulic pressure plate has a very bleak appearance because no vegetation can be formed on the surface visible from the outside.

On the other hand, before the anchor hydraulic pressure plate is installed, an anchor is provided in advance on the slope surface. In the construction process, a direction in which the anchor is inserted into the slope surface ("anchor penetration direction") and a direction in which the outer end of the anchor passes through the anchor- (The "anchor hydraulic plate penetration direction") do not coincide with each other frequently. FIG. 1 is a schematic side cross-sectional view showing when the anchor penetration direction and the anchor hydraulic plate penetration direction do not coincide. The anchor 6 is formed in the direction in which the anchor 6 penetrated into the slope face 9 extends, that is, in the anchor penetration direction and in the anchor hydraulic plate 100 made of a concrete member, The anchor 6 is hooked to the edge between the bottom surface of the anchor pressure plate 100 and the lower end of the through hole 15 so that the anchor 6 Is bent. That is, the anchor 6 contacts the corner indicated by the circle D in Fig. 1, and the anchor 6 is bent. When the anchors 6 are bent in such a manner as described above, the tension force of the anchors 6 can not act properly on the slopes. In addition, in the portions where the anchors 6 are in contact with the edges, the anchors 6 So that the anchor 6 may be broken.

In describing the present invention with reference to the drawings for convenience, the two directions orthogonal to each other in a plan view are referred to as a "first direction" and a "second direction", respectively. The steel beam constituting the anchor hydraulic pressure plate 100 of the present invention is subject to the condition that it has a sectional shape having a vertical web and an upper flange as will be described later, and a general I-shaped section The steel beam of the present invention has a lower flange but basically includes an upper flange and a web, and thus corresponds to a steel beam constituting the anchor hydraulic plate 100 of the present invention. That is, in the present invention, the steel beam constituting the anchor hydraulic pressure plate 100 may be an I-shaped or H-shaped cross section having not only a web and an upper flange but also a lower flange, It may be possible to have a cross-section made only of In describing the bottom plate constituting the anchor hydraulic pressure plate 100 of the present invention, the direction in which the bottom plate extends is referred to as "longitudinal direction ", and the direction perpendicular to the direction is referred to as" width direction ".

As shown in the drawing, the anchor hydraulic pressure plate 100 of the present invention is made of a steel material and has a cross shape in plan view. Specifically, the anchor hydraulic pressure plate 100 of the present invention includes a cruciform bottom plate 5 that is in contact with an upper surface of a sloped surface 9, and a criss-cross bottom plate 5 that extends in a width direction of the bottom plate 5 in a first direction A pair of first steel beams 1 integrally joined on the bottom plate 5 with a space therebetween and a bottom plate 5 spaced apart in the width direction in a portion extending in the second direction of the bottom plate 5, And a pair of second steel beams (2) integrally coupled to each other on the base plate (5).

Although the bottom plate 5 is shown as being composed of one plate member in a cross shape, the plate members extending in the first direction and the second direction with a predetermined width are not limited to this, (5). A pair of first steel beams (1) extending in the first direction and having a predetermined width and extending in the first direction are provided on the bottom plate (5) so as to be spaced apart in the width direction of the bottom plate And are integrally joined to each other by a method such as welding with the bottom plate 5 while being placed at the edge of the width of the plate. 2 to 8, the first steel beam 1 and the second steel beam 2 are not only the web 110 and the upper flange 111 but also the cross section having the lower flange 112 as well The lower flange 112 is placed on the upper surface of the bottom plate 5 and the lower flange 112 is integrally joined with the bottom plate 5 by welding or the like. However, in the present invention, the lower flange 112 may be omitted. In this case, the web 110 directly contacts the bottom plate 5, and the web 110 and the bottom plate 5 are welded .

A pair of second steel beams 2 are placed on the width edge of the bottom plate so as to have an interval in the width direction of the bottom plate and also on a portion of the bottom plate 5 having a predetermined width and extending in the second direction, And is integrally joined to the plate 5 by welding or the like. Each second steel beam 2 is not extended in the second direction and is cut off by the first steel beam 1 because the first steel beam 1 already exists, A portion of the second steel beam 2 is present between the pair of first steel beams 1, that is, the intermediate steel beam 220 indicated by the reference numeral 220 in the figure, and the second steel beam 2 Is substantially elongated in the second direction. When the second steel beam 2 is integrally coupled to the bottom plate, the content of the first steel beam 1 described above is applied equally.

 An end plate 4 is coupled to both ends of each of the first steel beam 1 and the second steel beam 2 in each direction. Therefore, a vegetation space in which plants can be planted is secured by the pair of first steel beams 1, the end plates 4 and the intermediate steel beam 220 in the first direction. Further, in the second direction, another vegetation space is ensured by the pair of second steel beams 2, the end plates 4 and the first steel beam 1 across the second steel beam 2 do. Fig. 9 is a schematic perspective view corresponding to Fig. 2 showing a state where plants are planted in the vegetation space. In the state where the anchor hydraulic plate 100 of the present invention is installed on the slope 9, And plants can be planted. As described above, since the anchor hydraulic pressure plate 100 of the present invention can easily secure the vegetation space, when the slope surface 9 is installed on the slope surface 9, the slope surface 9 can be videotaped through the plant material, Thereby making it possible to form an environmentally friendly slope surface appearance. In the vegetation space, it is preferable that a drain hole 50 is formed in the bottom plate 5. If the drainage hole 50 is formed, water can be prevented from being excessively accumulated in the vegetation space. In addition, when drying, moisture necessary for the plant can be introduced into the vegetation space through the drainage hole 50 Thus, it can be a great help to smooth vegetation of plants.

On the other hand, in the area surrounded by the first steel beam 1 and the intermediate steel beam 220, the bottom plate 5 is formed with an anchor through hole 60 through which the anchor 6 penetrates. 10 is a schematic perspective view showing a state before the anchor pressure plate 100 according to the first embodiment shown in Figs. 2 to 8 is placed on the slope 9 and the anchor 6 is fixed, and Fig. 11 shows a state after the anchor 6 is fixed following the state shown in Fig.

10 and 11, in the present invention, the anchor 6 is first fixed to the ground of the slope 9, and then the anchor pressure plate 100 is fixed so that the bottom plate 5 is in close contact with the slope 9, Is disposed on the slope surface (9). At this time, the outer end of the anchor 6, which is outside the slope 9, protrudes through the anchor through hole 60 to the outside. The fusing plate 61 is disposed so as to cover the upper flange 111 of each of the first steel beam 1 and the intermediate steel beam 220 and the anchor 6 passing through the fusing plate 61 is tensed, 6 is fixed to the fixing plate 61 so that the tension of the anchor 6 pressurizes the anchor pressure plate 100 in the direction of the slope 9 so that the collapse of the slope 9 is prevented . The fixing device may be composed of a wedge 32 and a wedge cone fixing port 31.

As described above, since the anchor hydraulic pressure plate 100 of the present invention is manufactured using a steel material beam having a cross section including a plate material (bottom plate) made of a steel material and an upper flange and a web, Materials can be easily procured. That is, since the anchor pressure plate 100 can be manufactured using a normal steel beam that is standardized and produced in the factory and easily available in the market, it is easy to procure the material, and the material cost is low, The anchor pressure plate can be manufactured.

In addition, since the anchor hydraulic pressure plate 100 of the present invention is made of a steel material and the upper surface of the bottom plate 5 is provided with an empty space for vegetation, the overall weight of the anchor hydraulic pressure plate 100 is light, And it is very easy to carry and handle. Especially, it is possible to use small equipment when performing transportation or installation work on a slope surface, thereby achieving a cost saving effect, There is an advantage that anchor hydraulic pressure plate can be easily installed on the slope even in a small site where large equipment is difficult to enter.

A large bending compressive force acts on the inner upper portion which intersects each other in the first steel beam 1 and the second steel beam 2 when the anchor 6 acts on the anchor pressure plate 100. [ Fig. 12 is a schematic side view of the anchor hydraulic pressure plate 100 taken on the slope 9 and the anchor 6 being fixed. As shown in the drawing, when an anchor tensioning force acts on the slope surface 9 in the ground direction (direction of arrow J), a bending moment acts on the anchor hydraulic plate 100 in the direction of arrow M, A large compressive force acts on the outer surface of the anchor hydraulic plate 100 at a position indicated by K, that is, at a position where the second steel beam 2 is disconnected by the first steel beam 1. [ Also, a large compressive force acts on the upper surface of the anchor hydraulic plate 100 at the position where the intermediate steel beam 220 is disposed in the first steel beam 1. [ In the present invention, since the anchor pressure plate 100 is formed by the steel beam having the upper flange 111, a large compression stiffness is exerted through the upper flange 111, so that the bending moment due to the anchor tensions, Even if a compressive force is applied thereto, there is an advantage that sufficient rigidity corresponding thereto is obtained.

If necessary, a reinforcing beam 8 having an upper flange and a web may be provided to the intermediate steel beam 220 in addition to the portion where the compressive force is expected to act largely by the bending moment as in the first embodiment shown in Figs. 2 to 8. [ So that it can be arranged in parallel with the first steel beam 1 between the pair of first steel beams 1. Of course, the reinforcing beam 8 can also be arranged in parallel with the second steel beam 1 between the pair of second steel beams 2 as well. The end of the reinforcing beam 8, which is disposed in the arrangement between the second steel beams 2, is joined to the side of the first steel beam 1. Of course, the reinforcing beam 8 may also be provided with a lower flange, and the reinforcing beam 8 is preferably integrally combined with the bottom plate 5 as well. With the provision of the reinforcing beam 8, the bending moment due to the tensional force of the anchor and the greater compressive resistance against the compressive force can be exerted.

Next, a second embodiment of the anchor hydraulic pressure plate 100 according to the present invention will be described with reference to an embodiment having a configuration that ensures that the anchors 6 are arranged in a straight line without being bent Explain.

Figs. 13 and 15 are schematic perspective views showing the anchor pressure plate 100 according to the second embodiment of the present invention in different directions, and Fig. 16 shows an anchor pressure plate 100 according to the present invention, A schematic top view of the hydraulic plate is shown. 17 shows a state in which the outer end of the anchor 6 passes through the anchor pressure plate 100 shown in Fig. 13 and the hemispherical position-adjusting and fixing device 3 is engaged with the outer end of the anchor 6 18 is a schematic side cross-sectional view taken along the line DD of Fig. 13 with respect to a state in which the anchor hydraulic pressure plate 100 shown in Fig. 17 is installed on the slope face 9 .

13 to 18, the anchor hole 60 is formed in a region surrounded by the first steel beam 1 and the intermediate steel beam 220, The penetrating member 11 is connected to the anchor hole 60 and is connected to the bottom plate 5. [ A reinforcing rib (19) may be further provided around the penetrating member (11).

A semi-spherical positioning and fixing device 3 is used for fixing the end of the anchor 6 after the anchor pressure plate 100 is installed on the slope 9 and the anchor 6 is tensed. The hemispherical position-adjusting and fixing device 3 has an anchor penetration direction in which the anchor 6 penetrates and extends through the slope 9 and an outer end of the anchor 6 which penetrates the penetration member 11, the anchor 6 is arranged so as to be tilted while keeping the straight line without bending, even if there is a difference in the inclination angle between the "anchor pressure plate through direction"

Specifically, as illustrated in detail in FIGS. 17 and 18, the hemispherical position-adjusting and fixing device 3 is composed of a hemispherical member in which spheres are cut in approximately half, and in the center thereof, Anchor holes 30 are formed. The hemispherical position-adjusting and fixing device 3 has a larger size than the through-hole 15 of the penetrating member 11. [ Therefore, the hemispherical convex portion of the hemispherical position-adjusting and fixing device 3 is located to block the entrance of the through hole 15 of the penetrating member 11, The outer end of the anchor 6 passing through the center anchor hole 30 passes through. The wedge 32 and the wedge cone fixing port 31 are connected to the outer end of the anchor 6 through the central anchor hole 30 so that the wedge 32 and the wedge cone fixing port 31 are coupled to each other. And is brought into close contact with the flat surface of the adjustment fixing device 3, whereby the anchor 6 is fixed.

The hemispherical position adjusting and fixing device 3 has a hemispherical shape so that when the hemispherical portion having the hemispherical shape for tightly fixing the anchor 6 closes the penetration member 11, The hemispherical portion of the position adjusting and fixing device 3 is automatically rotated to cover the entrance of the through hole 15 of the penetrating member 11 while being blocked.

The direction in which the through hole 15 of the penetrating member 11 extends is orthogonal to the inclined direction of the slope 9 when the anchor hydraulic pressure plate 100 is disposed on the slope 9. That is, the direction of penetration of the anchor hydraulic pressure plate is orthogonal to the slope face 9. The direction of the anchor 6 penetrating into the ground is also orthogonal to the slope face 9 so that the position of the anchor 6 and the position of the penetrating member 11 coincide with each other. 100), the anchor penetration direction and the anchor hydraulic plate penetration direction are completely aligned, and the anchor 6 will be taut and fixed while maintaining a straight line. 1, when the anchor penetration direction is not orthogonal to the slope face 9, the anchor penetration direction and the anchor hydraulic plate penetration direction are different from each other, and accordingly, the anchor 6 is attached to the anchor pressure plate So that the tension of the anchor 6 can not only be transmitted through the bent shape but also the anchor 6 can be damaged.

However, in the case of the second embodiment of the present invention shown in Figs. 13 to 18, even if the anchor penetration direction is not orthogonal to the slope face 9 and thus does not coincide with the anchor hydraulic plate penetration direction, The hemispherical portion of the hemispherical position-adjusting and fixing apparatus 3 is automatically rotated so as to keep the anchor 6 in a straight line and exists over the entrance of the through hole 15 of the penetrating member 11, 6 is fixed to the flat surface through the hemispherical position-adjusting and fixing device 3, the anchor 6 is not bent and can still maintain a straight shape. Thus, according to the present invention, regardless of whether the anchor penetration direction and the anchor hydraulic plate penetration direction coincide or not, the anchors 6 are always arranged in a straight line and are fixed in tension so that a tension force by the anchor 6 So that it can act smoothly on the anchor hydraulic pressure plate 100.

Particularly, in the anchor hydraulic pressure plate 100 of the present invention, when the shape of the penetrating member 11 is from the upper end to the lower end in the direction of the bottom plate 5 and the downwardly enlarging taper of the through- The anchors 6 do not come into contact with the edge between the bottom surface of the anchor pressure plate 100 and the lower end of the penetrating member 11 when the anchors 6 maintain the linear arrangement by the position adjustment fixing device 3. [ Therefore, the present invention has the additional advantage of being able to prevent damage and breakage of the anchor due to corner contact, which was a problem of the related art.
