The present invention relates to a support pile that is installed on the ground that requires tension and compression, and more particularly, to a support pile that can be used with less depth limit while being less affected by earth pressure.

In general, a screw pile is used for drilling by being mounted on a rotary output end of a drilling equipment such as an earth drill or auger for drilling. At this time, the screw file is integrally provided with a spiral rotary blade throughout the longitudinal direction.

Therefore, after the drilling operation, a circular hole is made, and pile work such as a concrete pile is performed. However, during the drilling operation, the remaining soil is discharged by the rotation of the rotary blades, and the work becomes dirty, and the drilling depth is limited by the influence of the earth pressure. Moreover, the heavy weight of the screw pile makes it difficult to handle.

In addition, the existing pile (pile) used for supporting the structure is composed of a flat state outside, there was a problem that excessive pile work must be made due to the problem that the settlement continues in the case of soft ground.

Therefore, the present invention is to solve the problems of the prior art as described above, the object of the present invention is to provide a support pile that can be used without limitation of the depth without being affected by the earth pressure and less discharge of soil.

It is also an object of the present invention to provide a support pile that can serve as a rock anchor (Rock ancher) as well as a pile to prevent or support settlement.

Specific means of the present invention for achieving the above object,

As a pile embedded in the ground connected to the heavy-duty rotary output stage such as earth drill or auger,

A hollow pipe having a predetermined length, the tip of which is inclined to form a slanted sharp portion, the rear end is provided with a circular long main pipe having a connecting flange connected to the rotary output end, the outer peripheral surface of the main pipe Spiral swivel blades are characterized by being provided integrally with one or more places.

At this time, the turning wing may be configured in a spiral rotated 360 degrees.

In addition, a blocking plate may be further installed at the front end of the main pipe.

According to the present invention, it is further characterized in that one or more intermediate pipes having one end connected to the rear end side connecting flange of the perforated pile and the fastening means are further provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view of the support pile 10 according to an embodiment of the present invention, Figure 2 is a cross-sectional view seen from the line A-A of FIG.

As shown in FIGS. 1 and 2, the support pile 10 includes a main pipe 12 and one or more swinging blades 14 integrally formed on an outer circumferential surface of the main pipe 12.

The main pipe 12 is made in the form of a hollow pipe having a certain length, the front end of the main pipe 12 is formed to be inclined sharp portion 13 so as to penetrate the ground well, the rear end of the figure As shown in FIG. 3, the coupling flange 15 is connected to the rotation output terminal 5a of the heavy equipment (eg, earth drill and auger) 5.

The main pipe 12 may be made of a metal material that is advantageous in tension and compression. At this time, in the sharp part 13, the hollow of the main pipe 12 is smoothly blocked with the blocking plate 16 as shown in FIGS. 4 and 5, or the blocking plate 16 is inclined as shown in FIG. 5 to prevent the inflow of soil. It is preferable to.

In the present embodiment, the sharp portion 13 has a cross-sectional shape that is simply cut inclined, but the present invention is not necessarily limited to such a shape, and may be modified in various forms.

The pivot vane 14 is configured to be helically rotated at a distance of 280 ° to 650 ° with respect to the center of the main pipe 12 in at least one place on a predetermined section of the outer circumferential surface of the main pipe 12. This is because the bearing force of the support pile 10 is weakened when the turning angle of the turning vane 14 is smaller than 280 ° and is affected by the earth pressure when the turning angle is larger than 650 °.

1 is a structure in which two turning blades 14 are provided and integrally installed in two places of the main pipe 12. As shown in FIG. In this case, the pivoting blade 14 may be installed in the main pipe 12 by welding, and the number of the pivoting blades 14 may be increased or decreased in consideration of the length of the main pipe 12 or the nature of the ground.

In addition, the revolving wing 14 may be configured to have a straight end as shown in FIG. 2 (a) or curved as shown in (b).

As such, the reason why the turning blade 14 is partially installed without being installed in the entire length section of the main pipe 12 is to reduce contact friction during drilling and to prevent the discharge of soil.

The support pile 10 configured as described above is used to be connected to the rotary output terminal 5a of the heavy equipment 5 as shown in FIG. 3. At this time, the connecting flange 15 of the upper end side of the support pile 10 is connected to the rotation output terminal 5a and moved to the working position.

Next, the support pile 10 is erected at the working position and starts to rotate. At this time, the vertical leveler is used to drive the support pile 10 vertically, and the vertical leveler is checked until the support pile 10 enters a predetermined depth, that is, until the vertical position is held.

In this state, when the rotary output terminal 5a is rotated in the direction of the arrow K, the sharp part 13 of the support pile 10 enters and buryes the ground layer 1, and the turning blade 14 is the main pipe 12. Induces the penetration into the strata (1) and at the same time serves to dig well.

At this time, since the turning wing 14 winds through the soil in the ground, the soil is not discharged to the upper ground layer.

In this way, if the support pile 10 is embedded in a certain depth, because the turning wing 14 is embedded in the ground it can play the following role.

First, as shown in Figure 6 it is possible to act as a rock anchor of the slope cut and the retaining wall (30). That is, it can be used as underground piles corresponding to soil pressure such as retaining walls and cut slopes.

Second, as shown in FIG. 7, the soft layer 32 may serve to support a structure 34 (a wooden wooden walkway, etc.) to be supported on the soft layer. Here, the soft layer means rock layer, sand or mud layer, swamp, etc.

Third, it can be used as a tension fixing pile required to tension the membrane member 36 of the membrane member structure as shown in FIG. That is, a fixing file is possible as the terminal bracket of the tensile membrane structure.

Fourth, as shown in Figure 9 it can be used as a support pile for the lower support structure, such as lighting tower 38, steel tower, column.

In addition, the present invention can be used as a support pile of the auxiliary cable for centering the structure before being fixed.

Therefore, the support pile 10 of the present invention may have various types of jigs (ZIG) 40 as shown in FIG. 10 to receive the structure 34 on its head. This jig 40 is installed by connecting the support pile 10 to meet the purpose after the vertical or horizontal work is finished.

The supporting file 10 installed in this way can be easily reversed in the reverse order of the file operation when dismantling. At this time, the rotation direction of the support pile 10 may also be made in the reverse order to facilitate the removal.

On the other hand, in the present invention, when the depth to which the support pile 10 is deepened, one end is connected to the rear end side cylindrical connection flange 15 and the fastening means (18, 19) of the perforated pile (12) as shown in FIG. One or more intermediate pipes 20 with fastening holes 20a may be added.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

As described above, according to the support pile of the present invention, it is possible to apply to both opposing operations such as tension and compression, and since the soil is not discharged, the work area is clean and no work such as curing is required, so that subsequent work is possible immediately. It is shortened. In addition, it is possible to work without noise by rotating instead of hitting, and it is possible to work up and down the pile so that it can be supplemented if necessary during the subsequent work, and the demolition can be done in the reverse order of laying.
