Specifically, the support pile of the solar panel for landfill installation according to the present invention,

The pile 10 is partially buried in the landfill ground and installed to support the solar panel; and

A support part composed of a housing 21 partially embedded in the ground while extrapolated to the pile 10 and having an internal pouring space, and a non-shrinkable mortar 22 poured into the ground in which the pouring space and the pile 10 are embedded. (20); includes.

A plurality of the piles 10 are partially buried in the ground of the landfill site and installed, and a frame (not shown) of the photovoltaic panel is inclined at a predetermined angle to the upper end of the piles 10 to be combined with a photovoltaic panel (not shown). ) is formed.

These piles 10 are made of a metal material,

As in the first embodiment shown in FIGS. 1 to 5, one pile 10 may be installed and installed,

Alternatively, as in the second embodiment shown in FIG. 6, it is composed of an upper pile 12 and a lower pile 13, so that the lower pile 13 is partially buried in the ground of the landfill and the upper pile 12 is exposed above the ground of the landfill. It may be installed and installed as two piles coupled to the top of the lower pile 13 .

And in the first embodiment, it can be seen that the pile 10 is composed of a U-file 10A having a 'C'-shaped cross-sectional structure,

In the second embodiment, a pile 10 composed of a helical pile 10B having a 'ㅁ'-shaped cross-sectional structure and a spiral engaging part 14 protruding from the outer circumferential surface of the buried part can be identified.

The U-pillar (10A) is connected to the flange portion 11, which is bent in the outer right-angled direction, respectively, to the ends of both sides of the opened portion while one side is opened.

This U file (10A) is a non-shrinkable mortar (22) is poured around the outer surface of the front and rear U file (10A) around the flange portion (11) as well as the empty space inside the U file (10A) to protect it by wrapping it do.

The helical pile (10B) has an empty hollow inside, and the engaging part 14 is spirally protruded along the longitudinal direction to the lower part of the part to be buried, and the lower part of the lower part of the file 13 in the drawing. has been

The helical pile 10B has a non-shrinkable mortar 22 poured around the empty space and the outer surface of the helical pile 10B to wrap the helical pile 10B. this is excellent

The housing 21 is made of a synthetic resin material that does not cause corrosion, and is preferably formed of a circular corrugated pipe as shown in FIG. 2 .

The housing 21 is installed in such a way that a lower portion of the housing 21 is embedded in the landfill ground and an upper portion of the housing 21 is exposed above the landfill surface while surrounding the outer circumference of the pile 10 with a predetermined width. do.

The non-shrinkable mortar 22 does not shrink when it is hardened after pouring. It contains an admixture having expandability in general cement mortar and a water reducing agent that improves fluidity while reducing the unit amount (amount of water contained per unit). Additively mixed, known grouting materials are used.

This non-shrink mortar 22 is poured not only inside the housing 21 but also into the ground in which the pile 10 is buried through an installation method to be described later, and the pile 10 made of a metal material is corroded from salt in the ground or prevent rusting.

Next, a method for installing a supporting pile of a solar panel for installation in a landfill according to the present invention will be described.

The support pile installation method of the solar panel for landfill installation according to the present invention,

a) installing the pile 10 partially buried in the ground of a landfill;

b) digging the buried part (D) in the ground surface around the upper end of the pile (10);

c) installing the housing 21 by being partially embedded in the embedding part D while extrapolating the housing 21 to the pile 10;

d) installing the support part 20 by pouring the non-shrinkable mortar 22 in the pouring space inside the housing 21 and the ground in which the pile 10 is buried.

In step a),

In the case of the U-pillar 10A, which is the first embodiment of the present invention, when the U-pillar 10A is buried in the buried hole after the buried hole is pre-worked, the 'C'-shaped cross section of the U-file 10A Due to the structure and the flange portion 11, a pouring space is naturally formed around the U-pillar 10A,

In the case of the helical pile 10B, which is the second embodiment of the present invention, the embedding operation is performed directly with the lower pile 13 of the helical pile 10B without first working the buried hole using the spiral engaging portion 14, The pouring space can be secured by extrapolating and embedding the buried pipe 15 in the upper part of the lower pile 13 where the locking part 14 is not provided, and the buried pipe 15 is the U of the first embodiment. It can also be applied to the file 10A.

When step a) is completed, the ground surface area in which the pile 10 is buried is dug to a predetermined depth to provide a buried part D, which is a space for embedding the housing 21, in which case the buried part D is the housing. Compared to the height of (21), 1/3 to 2/3 depth, preferably 1/2 depth.

And in the case of the first embodiment, the order of the steps a) and b) is irrelevant (that is, the burial work and the pile 10 burying work may be made after excavation),

In the case of the second embodiment, after embedding the helical pile 10B, the work of filling and compacting the ground portion through which the locking part 14 has passed may be added.

When step b) is completed in this way, as step c), the housing 21 is extrapolated to the pile 10 and inserted into the embedding part D to partially embed the housing 21 .

In this case, in the case of the first embodiment, after the steps b) and c), step a) may be performed,

In the case of the second embodiment, it is preferable that the assembly of the upper pile 12 proceeds in a state in which the housing 21 is first formed after the lower pile 13 is buried.

After completion of step c), the non-shrinkable mortar 22 is poured in step d).

The non-shrinkable mortar 22 poured in this way is poured into the housing 21 while being poured into the perimeter of the pile 10 buried in the landfill ground, and after curing, the pile 10 is protected from salt in the ground, at this time. Concrete pouring is also made in the internal space of the pile 10 , and the non-shrink mortar 22 increases the strength of the pile 10 itself while protecting the pile 10 .

In particular, since the non-shrinkable mortar 22 inside the housing 21 surrounds the pile 10 with the upper and lower portions of the ground surface, the salt of the ground surface rides the pile 10 exposed above the ground and corrodes the pile 10 . It can be prevented from rusting or rusting.

When the pouring and curing operation of the non-shrinkable mortar 22 is completed in this way, the installation operation of the solar panel is completed by installing the frame for the solar panel on the pile 10, and in the case of the second embodiment, the upper part before installation of the frame Installation of the file 12 is preceded.

On the other hand, when the housing 21 is buried in the step c) after the excavation of step b), the housing 21 cannot be accurately erected in the vertical direction, so that the non-shrinkable mortar 22 leaks to the outside of the housing 21 The housing 21 may be warped.

Accordingly, the present invention introduces a support ring 30 that can evenly hold the outer circumferential surface of the housing 21 during embedding and installation of the housing 21 .

As shown in FIG. 8 , the support ring 30 holds the embedded portion of the housing 21 by interpolating the housing 21 ,

The support ring 30 has a plurality of pressing means arranged radially upward and downward along the inner circumferential surface,

The pressing means includes an accommodating groove 31 connected to the embedding part D at the inner end, an inclined surface 32 formed on the lower side of the accommodating groove 31 , and the receiving groove 31 . A pressure ball 33, a support spring 34 for supporting the pressure ball 33 in the upper direction in the receiving groove 31, and a push plate provided on the bottom of the receiving groove 31 to be able to move forward and backward. (35) and a push spring (36) interposed between the bottom of the receiving groove (31) and the push plate (35) to push the push plate (35).

The support ring 30 has a ring shape in which the housing 21 is fitted, and after working the inner diameter of the embedding part D to the outer diameter of the support ring 30 in step b), the c) In the step, before the housing 21 is installed, the support ring 30 is first embedded in the buried part D and installed.

In this state in which the support ring 30 is installed, the pressure ball 33 is supported by the push plate 35 so that a part of it invades the buried part D, and the lower side is supported in contact with the inclined surface 32 and , the upper side is supported by hanging on the inner end of the upper surface of the receiving groove (31).

And when the housing 21 is inserted into the support ring 30, the housing 21 first contacts the upper side of the pressure ball 33 and then descends while pushing. The lower side of the pressure ball 33 is the inclined surface ( 32), the pressure ball 33 presses the end of the housing 21. The housing 21 whose surface is pressed by the pressing ball 33 cannot descend unless it is in a vertical state, so that the lower end of the housing 21 is leveled.

At this time, if the housing 21 is continuously pressed and inserted into the lower part, the housing 21 momentarily pushes the pressure ball 33 with a strong force while the pressure ball 33 receives a pushing force without rotating at that moment. The ball 33 is fixed by pressing the housing 21 as above without being blocked by the inclined surface 32 .

After the pressure ball 33 instantaneously presses the housing 21 to fix it, the housing 21 continues to push the pressure ball 33 downward, so the pressure ball 33 is pushed to the housing 21 and As it comes into contact with the surface of the housing 21 and rotates, it moves upward along the inclined surface 32, and the push plate 35 is pushed by the pressure ball 33 and rotates in the backward direction so that the pressure ball 33 enters the receiving groove ( 31), and at this time, the support spring 34 pushes the pressure ball 33 upward so as to be smoothly accommodated in the receiving groove 31. When the pressure ball 33 is accommodated in the receiving groove 31, the housing 21 descends without the interference of the pressure ball 33, and at this time, the push spring 36 moves the outer surface of the housing 21 inward. Because it pushes, the housing 21 can be embedded and installed in the embedding part D while maintaining the vertical state by the radially arranged pressing means.

In the above description of the present invention, with reference to the accompanying drawings, the support file and the installation method of the solar panel for installation in a landfill have been mainly described, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, and such modifications, changes and Substitution should be construed as falling within the protection scope of the present invention.
