Description

Technical Field [0001] The present invention relates to a compact pile for compacting pile for soft ground, and a compact pile for soft ground reinforcement,

The present invention relates to a pile for reinforcing soft ground, and more particularly, to a pile for reinforcement of sand, gravel, concrete or other mixture in a state where the tip is closed when penetrating into soft ground with equipment such as backhoe, The material for reinforced piles is increased by the continuous action of pulling and pressing in order to form reinforced piles through diffusion and sequential compaction. Compact piling device and soft pile reinforcing material using the same.

In general, soft ground refers to the ground that does not support the load of the superstructure, and it is an unstable foundation where the water content is high or the mud layer, clay ground, silty ground, soil layer, sand layer, There is a problem of sinking due to insufficient support force in the structure. Therefore, before installing the structure on the soft ground, the ground will be reinforced according to the use and size of the structure.

That is, when constructing the structure in the soft ground, considering the stability, settlement, liquefaction, permeability, etc., the structure is constructed after reinforcing the soft ground.

Conventionally, as a technique for reinforcing the soft ground, Korean Patent Laid-Open Publication No. 10-2013-0052158 has proposed a method of constructing a soft ground foundation file.

This includes the steps of drilling the ground with a perforator to form an injection hole; Inserting an injection tube connected to a lower portion of a tube formed of a waterproof material and capable of expanding in an injection hole formed by the perforator; And injecting the instantaneous expanding composition through the injection tube to form the base pile in such a manner that the instantaneous expanding composition expands the tube while the outer edge of the injection hole expands, And is formed to have a curved wrinkle along the longitudinal direction so as to expand the surface area when inflated by the inflating composition.

However, in the above case, the ground is strengthened through expansion of the injection pipe, which causes a problem that the surrounding ground can not be uniformly strengthened.

As another example, there has been proposed a soft ground foundation reinforcement facility for building sections using a Korean sleeper sleeping tester 10-0467086.

This is related to a foundation reinforcement facility for soft ground using construction of a sleeping tie. It is constituted to use a sleeping tie for soft ground so as to reinforce a soft ground with a grouting material to prevent a long-term subsidence of the ground. This paper deals with the soft foundation foundation reinforcement facilities.

In the soft ground foundation reinforcement facility using the sleeping tie which reinforces the ground before the construction of the soft ground, the soft ground foundation reinforcement facility is composed of the sleeping tie, the grouting material, the sleeping rail fixing frame, the fastening frame, The sleeping trough is provided in a vertical shape, and a grouting hole penetrating the upper surface and the lower surface is formed. A plurality of grouting holes are formed on the side surface so that the grouting material penetrates well. Wherein the grouting material is mixed with cement, water and an expanding agent to reinforce the ground by being inserted into the ground through a grouting hole in the upper part of the sleeper, and the grouting material is formed into a square shape And a rectangular shaped fastening portion formed with a fastening hole is formed around the fastening hole, The side fixturing baskets are constructed in the shape of a C-shaped upper part, and a circular cone file is formed in the lower side, so that the left and right side edges of the building section So as to reinforce the foundations of the soft ground.

Also, Korean Patent Application Laid-Open No. 10-2013-0052158 discloses a method of constructing a soft ground foundation file.

The present invention relates to a method of constructing a soft ground foundation pile, comprising the steps of: forming an injection hole by perforating a ground by a perforator; injecting a tube, which is inflatable in the injection hole formed by the perforator, And injecting the instantaneous expanding composition through the injection tube to form the base pile in such a manner that the instantaneous expanding composition expands the tube and extends beyond the injection hole, Is formed to have a curved wrinkle along the length direction so as to expand the surface area when inflated by the inflating composition. According to this soft foundation foundation file construction method, high-density polyurethane as an instantaneous expansion composition is injected into a stretchable tube to form a foundation pile, thereby providing an advantage of being easy to construct and suppressing environmental pollution.

However, in the case of the above-mentioned methods, it is possible to install a structure on a soft ground through penetration of a large number of files on a soft ground, and through a penetrated file, it is possible on a relatively large scale site. However, in a small area where a soft ground is not widely distributed, This has been a waste problem.

In other words, in the past, when it is desired to increase the synthetic strength of the soft ground, it is effective in a large-scale workplace by installing a large equipment such as a crane to set up a column. However, I have been.

The present invention relates to a soft ground reinforcement material for forming a reinforcing material compaction pile in a soft ground by continuous operation of pulling / press-fitting a steel pipe while injecting reinforcement material such as sand, gravel, concrete or other mixture through a steel pipe penetrated into a soft ground Pile small pouring device.

1 and 2, the soft ground pile reinforcing material compact pouring apparatus according to the present invention comprises a leading end penetration part 100 for penetration of soft ground, and a compaction part 100 for compaction of the reinforcing material charged in the soft ground, A guide part 300 for guiding the reinforcing material to the compaction part 200 and a hopper part 400 for mixing the reinforcing material and flowing into the compaction part 200 through the guide part 300. [ And a compaction unit 500 for causing the compaction unit 200 to repeatedly perform the drawing and press-fitting operations by connecting to a separately prepared known mechanical device.

3A, 3B, and 3C, when the reinforcing material is introduced into the hopper unit 400 while being penetrated into the soft ground, the reinforcing material is transferred to the compaction unit 200 through the guide unit 300 and filled And at this time, the consecutive repeated drawing / indenting operations of the compaction means 500 enable the compaction unit 200 to compact the reinforcing material in the soft ground.

That is, when the compaction unit 200 is lifted as shown in FIG. 3B, the compaction unit 200 is lifted by t1 and separated from the leading end penetration unit 100 by t1. At this time, the compaction unit 200 The reinforcing material is filled into the inside of the compartment 200 and the compaction unit 200 is continuously lowered to compose the reinforced material. At the same time, when the compaction unit 200 is raised by t2 in FIG. 3C, Is repeated continuously.

The reinforcing material is preferably sand, gravel, concrete or the like, as well as other mixtures.

The front end penetration part 100 is for penetrating perpendicularly to the soft ground and is intruded and separated from the compaction part 200 according to the operation of the compaction device 500. The engaging end 140 is formed at the other end of the wedge 120 so that the engaging end 140 is detachably coupled to the end of the compaction unit 200, do.

4A shows another example of the tip end penetration part 100. The tip end penetration part 100 is divided into at least two or more divided parts 150a, 150b, 150c and 150d And the one end of the divided and fixed part is fixed to the fixed cap 160 so that soft ground penetration is possible.

Accordingly, when the front end penetration part 100a is separated from the compaction part 200 in the soft ground, the divided parts 150a, 150b, 150c and 150d are horizontally tilted about the fixed cap 160 It has a form and it plays a role of compaction.

4B is another example of FIG. 4A, in which the leading end penetration part 100 is taken out together with the compaction part 200 without being buried in the ground during the drawing process.

The tip end penetration part 100b is composed of at least two divided parts 160a and 160b, and the upper ends thereof are positioned in such a manner as to surround the lower end of the compaction part 200, The upper ends of the divided bodies 160a and 160b are rotatably coupled through hinge hinges 180 and 181, respectively.

The compaction unit 200 includes a reinforcing material inflow space 210 whose one side is detachably coupled to the coupling end 140 of the front end penetration unit 100 and whose inside is larger than the inside diameter of the guide unit 300, . A compaction plate 220 is formed on the upper side of the reinforcing material inflow space 210 to press the reinforcing material introduced therein.

On the upper surface of the compaction unit 200, a swash plate 230 having an inclined surface is coupled along the perimeter so as to be able to be pulled out in the drawing operation of the steel pipe pile.

The guide portion 200 is hollow and has an inner diameter smaller than the inner diameter of the reinforcing material inflow space 210. One end of the guide portion 200 is communicably connected to the other center of the compaction portion 200, The reinforcing material inflow space 210 of the compaction unit 200 is guided.

As a result, the reinforcing material introduced into the guide portion 200 is filled in the reinforcing material inflow space 210 of the compaction unit 200, and when the compaction unit 200 is repeatedly moved up and down, The reinforcing material is pressed on the surface of the compaction plate 220 located on the upper side of the first compartment 210.

The hopper unit 400 is connected to the other side of the guide unit 300 and mixes the reinforcing material to be introduced into the guide unit 300 and the inclined surface 410 is formed inside.

The compaction unit 500 is installed on the outer side of the guide unit 300 and is detachably connected to a mechanical device capable of repeatedly moving up and down so that the guide unit 300 can be repeatedly moved up and down during operation.

That is, the compaction unit 500 includes a clamp 540 having a guide groove 520 for mounting a tool BT coupled to the equipment B such as a backhoe, outside the guide unit 300 Can be implemented.

This is not only an operation for pushing the tip end penetration part 100 into the soft ground, but also an operation for pulling out the tip end penetration part 100 in an initial state when the tip end penetration part 100 is penetrated into an appropriate position, It plays a role of repeating. Accordingly, the steel pipe is pulled out in the drawing process and the reinforcing material injected in the press-fitting process acts to compose the reinforcing material through the compaction plate 220.

Hereinafter, a procedure for compiling the soft ground through the steel pipe constructed as described above will be described.

First, as shown in FIG. 6, a steel pipe is vertically installed on a soft ground, and then a steel pipe penetration step (S1) is performed (see FIG. 5A). Then, as shown in FIG. 2, the reinforcing material is injected into the hopper part 400 provided on the side of the head of the steel pipe to mix the reinforcing material, and the reinforcing material is mixed into the guide part 300 of the steel pipe and the compaction part 200 at the tip A reinforcing material injecting step S2 is performed to fill the reinforcing material inflow space 210 (FIG. 5B). A clamping step S3 of connecting the end of the tool BT provided in the equipment B such as a backhoe to the guide groove 520 of the clamp 540 provided in the guide part 300 of the steel pipe is performed 5C). When the reinforcing material compaction step (S4) is performed in which the reinforcing material is successively repeatedly pulled and press-fit repeatedly to put the reinforcing material into the soft ground and compaction thereof, the soft ground is gradually compaction (See FIG. 5D). When the steel pipe is pulled out from the soft ground while the compaction is completed, a new steel pipe is installed on another soft ground. At this time, a new leading end penetration part 100 may be used by being coupled to the compaction part 200. When the above operation is repeated, as shown in FIGS. 7 and 8, a plurality of compaction piles st are formed on the soft ground, and the construction is completed.

In the steel pipe penetration step S1, the steel pipe may be vertically installed on the surface of the soft ground, and then the steel pipe may be inserted into the soft ground through a machine such as a hanger. At this time, the wedge 120 constituting the tip penetration part 100 can be intruded while penetrating the soft ground, so that the wedge 120 can be quickly penetrated.

The front end penetration part 100 can be detached from the compaction part 200 and can be integrally connected to the compaction part 200 through a hinge 180. In this case, after forming the compaction pile (st), it is possible to continuously penetrate into the surrounding area.

The reinforcing material injecting step (S2) may be applied with a reinforcing material for forming a reinforcing pile for reinforcing on the soft ground, preferably sand, gravel, concrete, and other mixtures.

The reinforcing material selected from the above materials may be injected into the hopper part 400 and the reinforcing material may be mixed in the hopper part 400 and the reinforcing material inflow space of the compaction part 200 210).

In the clamping step S3, the tool BT at the tip of the boom capable of vertically flowing in the construction equipment B such as a backhoe is engaged with the guide groove 520 of the clamp 540 constituting the compaction means 500, . At this time, when the tool B is moved up and down, the compaction unit 500 moves the guide unit 300 up and down so that the compaction unit 200 moves up and down.

The reinforcing material compaction step S4 may be repeated until the tool BT selectively coupled to the guide groove 520 constituting the compaction means 500 is continuously or upwardly or downwardly repeated by the operation of the construction equipment B, So that it is gradually moved upwards for withdrawal.

Then, the compaction plate 220 constituting the compaction unit 200 is moved upwards simultaneously with the upward and downward movement of the compaction unit 200 to form the compaction pile st by compaction of the reinforcing material, .

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention.
