FIG. 2 is a view showing an overall structure of a landfill according to an embodiment of the present invention. FIG. 3 is a perspective view of a ground supporting structure according to an embodiment of the present invention, Fig. 3 is a view showing the overall structure of the landfill structure for land use. Fig.

As shown in the figure, the ground embedding structure according to the present invention comprises an upper slider 100 and a lower slider 200, and a plurality of supports 300 ) Are connected to each other.

The upper slider 100 and the lower slider 200 are installed to be slidable along the longitudinal direction of the strut P and the lower slider 200 is spaced or disposed on the lower portion of the upper slider 100 .

The support part 300 connects the upper slider 100 and the lower slider 200 to each other, and is installed to be foldable. As the distance between the upper slider 100 and the lower slider 200 is varied, the shape of the support part 300 also varies on the support pillars P.

2, when the upper slider 100 and the lower slider 200 are separated from each other by a certain distance on the support platform P, the support member 300 is placed at a predetermined angle in the radial direction of the support bar P 3, when the upper slider 100 and the lower slider 200 are as far as possible on the support bar P, the support part 300 is placed in a direction parallel to the longitudinal direction of the support bar P . That is, the support part 300 may be placed in a triangular shape or in a straight line.

In the illustrated embodiment, only the supporting portion 300 is shown in two forms. However, as the distance between the upper slider and the lower slider is varied, it is known that the supporting portion may be provided in various other forms. There will be.

Since the support part 300 is placed so as to have a predetermined angle in the radial direction of the support bar P, the support part 300 is firmly supported by the load of the earth when the support bar P is buried, Do not fall.

The pillars P may be made of any one or a combination of wood, plastic material, steel material, or alloy material depending on the types of facilities installed, such as an electric signboard, a signboard, a milestone, and the like.

The support pillars P may have any one of circular, elliptical, quadrangular or polygonal shapes (for example, hexagonal, octagonal, etc.) in consideration of the type of facility to be installed, 100 and the lower slider 200 are formed in a ring shape having a circular cross section, an elliptical cross section, a rectangular cross section, or a polygonal cross section corresponding to the outer peripheral surface shape of the support column P.

The diameter of the upper slider 100 and the lower slider 200 may be substantially equal to or slightly larger than the diameter of the support bar P and may be freely slidable along the lengthwise direction of the bar support P.

The upper slider 100, the lower slider 200, and the support 300 may be partially or wholly buried in the ground. The upper slider 100, the lower slider 200, and the support 300 may be made of a material having rigidity and corrosion resistance so as to withstand the load of the soil desirable.

Specifically, the upper slider 100, the lower slider 200, and the support 300 include 0.02 to 0.05 wt% of carbon (C), 0.1 to 1.0 wt% of silicon (Si), 12 to 24 wt% of chromium 10 to 14 wt% of nickel (Ni), the balance of iron (Fe) and other unavoidable impurities.

Since the carbon (C) is an element for work hardening of the alloy material, if it exceeds 0.05 wt%, it may cause intergranular corrosion, so it is limited to less than that, and silicon (Si) is an element added as a deoxidizer or 1.0 wt% (Cr) is an element for improving the corrosion resistance, and if it exceeds 24 wt%, it affects the content of delta ferrite in the base material at the time of solidification, so that it is limited to less than that, and nickel (Ni) is an element for maintaining the phase balance, and the effect is insignificant when it exceeds 24 wt%.

Since the upper slider 100, the lower slider 200, and the support 300 are made of a material having superior rigidity and corrosion resistance, the support bar can be supported without being damaged for a considerable period of time after the support bar is embedded.

A plurality of upper brackets 110 and a plurality of lower brackets 210 project radially from the outer circumferential surfaces of the upper slider 100 and the lower slider 200, respectively. That is, the support part 300 is not directly connected to the upper slider 100 and the lower slider 200 but is connected to the upper slider 100 and the lower slider 200 through the upper bracket 110 and the lower bracket 210.

The upper bracket 110 and the lower bracket 210 are protruded outward in a direction orthogonal to the longitudinal direction of the support column P. The upper bracket 110 and the lower bracket 210 are deployed in the form of a yoke about the upper slider 100 and the lower slider 200 when the upper slider 100 and the lower slider 200 are viewed from above.

The lower bracket 210 is coupled to the lower end of the lower slider 200 to support the lower end of the strut P so that it can stand vertically in the ground / ground without any device.

The upper bracket 110 and the lower bracket 210 can be separated from the outer circumferential surfaces of the upper slider 100 and the lower slider 200 so that the upper and lower ends of the support 300 can be coupled with each other, It is possible to prevent the outer circumferential surfaces of the upper slider 100 and the lower slider 200 from being damaged during the folding of the support portion 300 and to provide space for the upper and lower ends of the support portion 300 to rotate.

The upper bracket 110 and the lower bracket 210 may be integrally formed with the upper slider 100 and the lower slider 200 or may be coupled to the upper slider 100 and the lower slider 200 through welding or the like.

A plurality of fixing holes 120 and 220 are formed in the side portions of the upper slider 100 and the lower slider 200 so as to extend through the upper slider and the lower slider to the side of the strut P.

As described above, the gap between the upper slider 100 and the lower slider 200 can be varied. The user can adjust the distance between the upper slider 100 and the lower slider 200 in consideration of the ground rock, soil characteristics, After the relative position of the slider 200 is determined, the fixing bolts are inserted into the fixing holes 120 and 220 to fix the upper slider 100 and the lower slider 200.

The upper and lower sliders 100 and 200 are pressed and supported between the head of the fixing bolt and the outer surface of the support bar by pushing the fixing bolt through the fixing holes 120 and 220 and pressing the outer surface of the support bar P do.

4 is a view showing a state of a support according to an embodiment of the present invention.

The supporting part 300 includes a first supporting part 310 whose upper end is rotatably coupled to the upper slider 100 and a second supporting part 320 whose lower end is rotatably coupled to the lower slider 200, .

The lower end of the first support part 310 and the upper end of the second support part 320 are connected to each other by a rotation bolt 330 and the first support part 310 and the second support part 320 320 are rotated, the supporting portion 300 is folded.

Slots 340 are formed at the upper and lower ends of the first and second support portions 310 and 320 along the longitudinal direction of the first and second support portions 310 and 320. The rotation bolt 330 connecting the first support part 310 and the second support part 320 is slidable along the slot 340.

The first support 310 and the second support 320 may be coupled to each other in a state where the slots 340 are formed as long holes and the rotation bolts 330 are slidably coupled along the slots 340, So that the folding operation of the first support portion 310 and the second support portion 320 can be much more natural.

The space between the first support part 310 and the second support part 320 may be formed so that the folding operation can be smoothly performed even when the dust is stuck, It is absolutely necessary.

A plurality of support grooves 350 are formed in the side portions of the first support portion 310 and the second support portion 320. The plurality of support grooves 350 are spaced apart from each other on the sides of the first support portion 310 and the second support portion 320. In the illustrated embodiment, three support grooves 350 are formed on one side, but the present invention is not limited thereto.

The support groove 350 is effective when the first support portion 310 and the second support portion 320 are embedded in the ground so that the first support portion and the second support portion can be firmly fixed in the ground .

5 is a view showing an end view of a first support according to another embodiment of the present invention.

As shown, in another embodiment of the present invention, the slot 340 includes a receiving slot 341 in which the rotating bolt 330 is received and temporarily fixed, and a receiving slot 341 in which the receiving slot 341 is connected to the connecting slot 342 And includes a mobile slot 343 through which the rotating bolt 330 can slide.

The diameter of the receiving slot 341 is formed to be approximately equal to or similar to the diameter of the rotating bolt 330 and the diameter of the receiving pawl 341 is set to approximately the same or similar to the diameter of the rotating bolt 330, The rotation bolt 330 is received in the receiving slot 341. [

The width of the movable slot 343 is formed to be relatively larger than the diameter of the rotation bolt 330. This is for securing a space in which the rotating bolt 330 can move when an impact is applied to the support pawl, the upper slider 100, the lower slider 200, or the supporter 300.

In other words, the receiving slot 341 and the moving slot 343 have a shape similar to the 'snowman' shape as a whole, and the receiving slot 341 and the moving slot 343 are connected to the connecting slot 342, .

It is preferable that the width of the connection slot 342 is relatively smaller than the diameter of the rotation bolt 330 because the rotation bolt 330 is normally received in the receiving slot 341, 342 are temporarily elastically or plastically deformed to move to the movable slot 343.

Since the lower end of the strut P is buried in the soil, an excessive load may be applied to the supporting portion 300. In the process of installing the strut P, a temporary impact may be applied to the supporting portion 300. At this time, the rotation bolt 330 moves from the receiving slot 341 to the moving slot 343 to buffer a load (shock) temporarily applied to the supporting portion 300 to some extent.

Although the receiving slot 341 and the moving slot 343 are formed at one end of the first support 310 in the illustrated embodiment, one end of the second support 320 or the first support 310 May be formed in the same shape at the other end portion.

The dispersion unit 360 may be formed to be convex so that the rotation bolts 330 are in surface contact with the ends of the first and second support units 310 and 320 adjacent to the slots 340. In the illustrated embodiment, the dispersion unit 360 is formed on one side of one end of the first support unit 310, but may also be formed on one side of the other end of the second support unit 320. It is preferable that the dispersion part formed on the second support part 320 is formed on the opposite side so as not to collide with the dispersion part 360 formed on the first support part 310.

Since the dispersing unit 360 is in surface contact with the rotating bolt 330 to disperse the load applied to the rotating bolt over a large area, the circumference of the slot 340 can be prevented from being torn by the impact of the rotating bolt 330 have. In consideration of various forms of the rotation bolt 330, the dispersing unit 360 is formed in a shape in which a plurality of angled corners are formed in a polygonal shape.

6 is a view showing an end view of a first support according to another embodiment of the present invention.

As shown in the figure, in the present invention, a pair of extension brackets 370 are coupled to the one side edge of the first support part 310 along the longitudinal direction of the first support part 310, (371) is slidably inserted.

The extension bracket 370 has a U-shaped cross section and a fixing portion 372 for fixing the position of the extension portion 371 is coupled to the upper portion of the extension bracket 370. The fixing portion 372 penetrates the extension bracket 370 and presses the upper portion of the extension portion 371.

The extension portion 371 is formed in a U shape as a whole and slides along the longitudinal direction of the first support portion 310 and protrudes outward of the first support portion 310 or is housed in the first support portion 310 . As the extension portion 371 is formed in a U shape, there is no interference with the slot 340 and the rotation bolt 330, and a certain amount of soil may pass through the extension portions 371.

The user can store the extension portion 371 in the extension bracket 370 of the first support portion 310 to increase the ease of transportation while transporting the support stand P and to extend the extension portion 371 when the support stand P is to be buried in the ground The effect of extending the length of the first support portion 310 can be achieved by pulling out the portion 371 from the extension bracket 370 and fixing the portion 371 through the fixing portion 372. When the extension 371 is extended, the first support 310, the second support 320, and the extension 371 may be disposed in the shape of a 'g'.

In other words, the extension part 371 extends from the first support part 310 when buried in the ground, so that the support part 300 can be buried in the form of a tree roots, Can be further increased.

FIG. 7 is a view showing the overall structure of a ground embedding structure for a support structure when the upper slider and the lower slider are brought into contact with each other according to an embodiment of the present invention.

As shown in the figure, when the lower end of the upper slider 100 and the upper end of the lower slider 200 are in contact with each other, the first support portion 310 and the second support portion 320 are disposed to have a predetermined inclination angle toward the upper portion .

This is because the length of the first support portion 310 is relatively shorter than the length of the second support portion 320 so that the second support portion 320 gradually moves toward the upper slider 100 as the lower slider 200 slides toward the upper slider 100. [ 1 toward the support 310.

Various types of rocks may be present during the landfill of the pillar (P). For example, there may be solid rock masses on both sides of the landing zone, and in some cases, there may be only a space where only the bottom of the landing zone can enter.

If the first support part 310 and the second support part 320 are arranged to be in a triangular shape as described above, the support part 300 is caught by the rock, so that the support bar P can not be installed properly. At this time, the user can adjust the rocker to be positioned at the lower part of the support part 300 by bringing the lower slider 200 upward so as to completely contact the upper slider 100.

In particular, since the rock mass existing in the ground often has a circular shape or a protruded shape, the first support portion 310 and the second support portion 320 may have a predetermined inclination angle toward the upper portion And minimizes the possibility of interference with rock mass.

3, when the upper slider 100 and the lower slider 200 are spaced apart from each other as much as possible, the first and second supporting portions 310 and 320 are spaced apart from each other by a distance When the upper slider 100 and the lower slider 200 are completely in contact with each other as shown in FIG. 7, the first and second support portions 310 and 320 are arranged in a straight line along the longitudinal direction, The first and second support portions 310 and 320 are disposed such that the upper slider 100 and the lower slider 200 are separated from each other by a certain distance therebetween as shown in FIG. Are arranged in a triangular shape.

Hereinafter, a method of installing the underground embankment for a ground support according to an embodiment of the present invention will be described.

FIG. 8 is a view schematically showing a structure in which an underground embedding structure for a landing girder according to an embodiment of the present invention is installed in the ground, and FIG. 9 is a view illustrating a method for installing a landfill for a landing girder according to an embodiment of the present invention. Fig.

The upper slider 100, the lower slider 200 and the supporting portion 300 are coupled to the lower end of the strut P, and then the upper slider 100, the lower slider 200, The first support part 310 and the second support part 320 are arranged in a straight line along the longitudinal direction of the support pillars P so as to be spaced from each other as much as possible.

Since the first support part 310 and the second support part 320 arranged in this state do not substantially increase the volume of the support platform P, the transportation is very easy. The user constructs the upper slider 100 and the lower slider 200 corresponding to the shape of the support bar P and joins the support bar to the support bar.

Upon reaching the landfill site, a digging operation is performed on the ground (S20). The ter- minator is made by avoiding rock masses and the like, which have a space size sufficient for the lower end of the column P to be buried, and which are difficult to remove.

The upper slider 100 and the lower slider 200 are slid along the longitudinal direction of the column P in consideration of the arrangement of the rock mass in the ground due to the earthquake, soil characteristics, and the like (S30)

As the upper slider 100 and the lower slider 200 are slid, the plurality of supports 300 are placed in a triangular shape having a predetermined angle in the radial direction (S40). Of course, as described above, the support portion 300 may be disposed to face upward as the case may be.

When the shape of the support part 300 is determined, the fixing bolts are combined with the upper and lower sliders 100 and 220 formed on the side of the lower slider 100 to form the upper slider 100 and the lower slider 200 200 are fixed on the pillars P (S50).

The lower end of the support bar P including the upper slider 100, the lower slider 200 and the support part 300 that has been fixed is placed in the ground where the tread is finished and the soil is buried in the ground to complete the installation of the support bar P (S60).

At this time, the user may adjust the position of the support platform P little by little in consideration of the state of the ground or rotate the support platform P to prevent the support member 300 from interfering with the rock, 300 may be removed.

As shown in FIG. 8, the support pillars P buried in the ground have a structure in which a plurality of supports 300 are firmly fixed by the load of the soil, so that they can be installed firmly without a concrete foundation block.

In this case, it is preferable that the upper slider 100 is disposed so that the lower end thereof is buried in the ground and the upper end thereof is exposed on the ground surface. This is because the upper end of the strut bed P exposed on the ground surface does not directly contact the ground, So that the slider 100 is brought into contact with the ground, thereby preventing contamination such as corrosion of the top of the support pillars.

As described above, since the support pillars P can be installed without the concrete foundation block, the construction period and the construction cost are remarkably reduced compared to the conventional method of casting concrete.

In addition, since the support parts 300 can be folded by simply sliding the upper slider 100 and the lower slider 200 on the support platform P, it is very easy to carry to the installation site, It is advantageous to install the tether stand only when the tether is installed at the installation site.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Will be clear to those who have knowledge of.
