Abstract
Description
Technology Field
[0001] The present invention relates to a pile installation structure using a wedge and a pile installation method using the same.
[0002] More specifically, the invention relates to a pile installation structure using a wedge and a pile installation method using the same, wherein an auxiliary pipe with a lower wedge attached to its upper outer circumference is buried and fixed in the ground, and a main pipe with an upper wedge attached to its lower inner circumference is connected so that the lower wedge and the upper wedge interlock with each other. Background Technology
[0003] Piles that support above-ground structures, such as supporting the frame of a vinyl greenhouse, supporting the connection part of a temporary structure like a tent, or supporting a post of a steel mesh fence, have their lower part embedded in the ground and are configured to support the above-ground structure by the surface friction force, which is the frictional force between the outer surface of the pile and the surrounding ground.
[0004] Therefore, while increasing the driving depth or expanding the outer diameter of the pile can secure its bearing capacity, i.e., pull-out resistance, such extension and expansion entail an excessive increase in construction costs, which poses a problem in terms of limited application.
[0005] Accordingly, a method is being applied to maximize pull-out resistance under limited pile specifications and depths by forming lateral protrusions on the outer surface of the pile to expand the contact area between the pile and the ground and allowing the protrusions to suppress the movement of the pile.
[0006] Various types of protrusions are applied to the outer surface of these piles, ranging from simple wedge-shaped protrusions to spiral protrusions that can minimize disturbance to the surrounding ground through rotational indentation.
[0007] One of the technologies related to this is disclosed in Korean Patent Publication No. 10-2015-0062900, which describes an underground spreading double pile.
[0008] The above-described conventional underground double pile is composed of an outer pipe having a cross-section in which transverse protrusions and recesses are formed at radial, equal intervals, with a sharply formed lower end and a plurality of radially formed cuts at the lower end, wherein an inclined plate is bent and formed inside the cuts, and an inner pipe having the same shape as the inner pipe and having a plurality of cuts and a divided end plate formed at the lower end; and is characterized by the fact that after driving the outer pipe into the ground, the inner pipe is inserted into the outer pipe and driven, causing the divided end plate at the lower end of the inner pipe to be laterally curved and developed by the inclined plate, thereby penetrating into the ground at an angle.
[0009] However, the above-mentioned conventional technology has a problem in that, since there is no configuration connecting the outer tube and the inner tube, even if the divided end plate of the inner tube is buried underground, a gap is created between the outer tube and the inner tube when repeated external force is applied to the outer tube, thereby reducing the pull-out resistance of the outer tube.

[0026] The present invention relates to a pile installation structure using a wedge and a pile installation method using the same, wherein an auxiliary pipe with a lower wedge attached to its upper outer circumference is buried and fixed in the ground, and a main pipe with an upper wedge attached to its lower inner circumference is connected so that the lower wedge and the upper wedge interlock with each other, thereby making it easy to install the main pipe on the ground.
[0027] Hereinafter, a pile installation structure using a wedge according to the present invention and a pile installation method using the same will be described in detail with reference to the attached drawings.
[0028] FIG. 1 is a drawing showing a pile installation structure using a wedge according to the present invention, FIG. 2 is a drawing showing an embodiment of a pile installation structure using a wedge according to the present invention, FIG. 3 is a drawing showing a base part of a pile installation structure using a wedge according to the present invention, FIG. 4 is a drawing showing a pile part of a pile installation structure using a wedge according to the present invention, FIG. 5a and FIG. 5b are drawings showing the interlocked state of a lower wedge and an upper wedge of a pile installation structure using a wedge according to the present invention, FIG. 6a and FIG. 6b are drawings showing a coupling groove and a stopper of a pile installation structure using a wedge according to the present invention.
[0029] According to the attached FIGS. 1 to 6b, the pile installation structure using a wedge according to the present invention includes a base part (100) and a pile part (200).
[0030] The pile installation structure using the wedge of the present invention is configured to be installed using the lower wedge (120) of the base part (100) and the upper wedge (220) of the pile part (200), thereby having the advantage of not requiring separate equipment for installing the pile.
[0031] The above base part (100) is fixed by being inserted into the ground in at least a portion, thereby making it easy to fix the pile part (200) described later to the ground.
[0032] The above-mentioned base portion (100) includes an auxiliary pipe (110) in which a lower portion is buried underground, and a lower wedge (120) installed on the upper outer circumference of the auxiliary pipe (110).
[0033] At this time, the auxiliary pipe (110) is configured to be inserted into the interior of the main pipe (210) described later, and as previously mentioned, a portion of its lower part is buried underground so that the main pipe (210) described later can be easily fixed.
[0034] In addition, the lower wedge (120) can be formed in a shape corresponding to the upper wedge (220) described later, so that they interlock with each other.
[0035] The pile portion (200) is configured to form the exterior of a pile and is coupled to the base portion (100), which is configured to be fixed by being buried in the ground in at least a portion, so as to have excellent pull-out resistance.
[0036] The above-mentioned pile section (200) includes a main pipe (210) coupled to the outside of the auxiliary pipe (110) and an upper wedge (220) installed on the lower inner circumference of the main pipe (210) and formed in a shape corresponding to the lower wedge (120) so as to engage with the lower wedge (120) when the main pipe (210) is coupled to the outside of the auxiliary pipe (110).
[0037] At this time, the main pipe (210) is configured to be connected to the auxiliary pipe (110) through the upper part of the auxiliary pipe (110), and as described above, the upper wedge (220) installed inside is configured to engage with the lower wedge (120) and can be configured to be fixed to the ground.
[0038] More specifically, the lower wedge (120) may be configured to have a structure in which the diameter gradually increases from the top to the bottom, and the upper wedge (220) may be configured to have a structure in which the diameter gradually decreases from the top to the bottom so as to interlock with the lower wedge (120) according to the connection of the main pipe (210).
[0039] That is, since the shape of the lower wedge (120) is formed such that the diameter gradually increases from the top to the bottom, the upper wedge (220) is joined along the shape of the lower wedge (120) as the main pipe (210) is inserted, thereby allowing for a forced fit as the main pipe (210) is inserted and configured to interlock with gradually stronger force.
[0040] Meanwhile, the pile installation structure using a wedge may further include a fixing part (300) configured to prevent shaking of the auxiliary pipe (110) by being configured so that at least a portion of it is buried in the ground while penetrating by the auxiliary pipe (110).
[0041] The above-mentioned fixing part (300) may include a fixing plate (310) placed on the ground, a central hole (320) formed in the center of the fixing plate (310) and configured to be penetrated by the auxiliary pipe (110), and a fixing wing (330) configured to extend downward from the fixing plate (310) and be buried underground to fix the fixing plate (310) to the ground.
[0042] That is, the fixing part (300) can fix the auxiliary pipe (110) to the ground by burying the fixing wing (330), which protrudes downward from the fixing plate (310) while the auxiliary pipe (110) is fixed through the central hole (320) formed in the fixing plate (310).
[0043] To this end, the central hole (320) formed in the fixed plate (310) may be formed with a size corresponding to the outer circumference of the auxiliary pipe (110), and may be configured so that the pull-out resistance of the auxiliary pipe (110) is improved when the fixed plate (310) is installed.
[0044] Additionally, the lower wedge (120) may be configured to have a coupling groove (121) formed in a shape that is recessed inward along the lower circumference, and the upper wedge (220) may include a stopper (221) that protrudes inward along the lower circumference and is configured to be inserted into the coupling groove (121).
[0045] The above-mentioned coupling groove (121) and stopper (221) are configured to improve the coupling force between the lower wedge (120) and the upper wedge (220), and after the lower wedge (120) and the upper wedge (220) are coupled to a certain depth or more, the stopper (221) of the upper wedge (220) is inserted into the coupling groove (121) of the lower wedge (120) so that the upper wedge (220) is not detached from the lower wedge (120), thereby improving the coupling force between the main pipe (210) and the auxiliary pipe (110).
[0046] That is, when the upper wedge (220) is joined through the upper part of the lower wedge (120) and the stopper (221) of the upper wedge (220) is inserted into the joining groove (121) of the lower wedge (120), the main pipe (210) can be configured so as not to be detached from the auxiliary pipe (110).
[0047] In the present invention, a coupling groove (121) is formed in the lower wedge (120) and a stopper (221) is formed in the upper wedge (220), but depending on the implementation environment, it may be configured so that a stopper is formed in the lower wedge (120) and a coupling groove is formed in the upper wedge (220).
[0048] FIG. 6 is a drawing showing a pile installation method using a pile structure according to the present invention.
[0049] According to the attached FIG. 1, the pile installation method using a pile structure according to the present invention includes a first joining step (S10), a second joining step (S20), a burial step (S30), and an installation step (S40).
[0050] The first joining step (S10) is a step of joining a lower wedge (120) to the upper outer circumference of an auxiliary pipe (110), and the second joining step (S20) is a step of joining an upper wedge (220) to the lower inner circumference of a main pipe (210).
[0051] The above first joining step (S10) and second joining step (S20) are configured such that a lower wedge (120) is installed on the outer circumference of the auxiliary pipe (110) and an upper wedge (220) is installed on the inner circumference of the main pipe (210), thereby enabling the auxiliary pipe (110) and the main pipe (210) to be easily joined in the subsequent installation step (S40).
[0052] The above burial step (S30) is a step of burying the lower part of the auxiliary pipe (110) underground.
[0053] At this time, the burial of the auxiliary pipe (110) can be configured to be performed by striking the upper part of the auxiliary pipe (110) while the auxiliary pipe (110) is erected and fixed on the ground, and such burial of the auxiliary pipe (110) can be performed using a separate tool.
[0054] The above installation step (S40) is a step of inserting the main pipe (210) into the upper part of the auxiliary pipe (110) so that the lower wedge (120) and the upper wedge (220) interlock with each other.
[0055] The above installation step (S40) is configured such that when the main pipe (210) is inserted into the upper part of the auxiliary pipe (110), the auxiliary pipe (110) is inserted into the interior of the main pipe (210), and the upper wedge (220) gradually spreads out according to the shape of the lower wedge (120) to force-fit it.
[0056] That is, the auxiliary pipe (110) is inserted into the interior of the main pipe (210), and the lower wedge (120) is forcibly fitted into the interior of the upper wedge (220), so that the main pipe (210) is coupled to the auxiliary pipe (110) and the pile portion (200) is fixed to the base portion (100).
[0057] According to the present invention, when an auxiliary pipe with a lower wedge attached to its upper outer circumference is buried and fixed in the ground, a main pipe with an upper wedge attached to its lower inner circumference is connected so that the lower wedge and the upper wedge interlock with each other, thereby providing the effect of making it easy to install the main pipe on the ground.
[0058] Although various embodiments of the present invention have been presented and described in the above description, the present invention is not necessarily limited thereto, and those skilled in the art will understand that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
