The present invention relates to the construction of mixed soil, and in particular, by adjusting the height of the column selectively according to the pouring height of the mixed soil to solve the conventional problem that the high column hinders the work when placing the mixed soil at once, the pillar inside the panel to form a fence Panels that allow the fence to be securely supported by embedding it so that the exterior is not smooth and corrosion occurs due to the exposed pillars, and the reinforcement mounted on the back of the fence is embedded in the mixed soil. The present invention relates to a fence using a panel, a method for constructing a fence, and a method for constructing a mixed soil structure using the fence.

In general, when soil is filled or backfilled in a place where the ground is soft, when a slurry made by mixing solidified fire and air bubbles in the field-collected soil is supplied to the soft place and landfilled, the lightweight soil and solidified fire harden and react chemically. The construction method to stabilize the soil properties to improve the soft ground is used.

In the conventional case, the method of constructing a reinforcement soil retaining wall in a place where the ground is soft is to build a wall by stacking heavy concrete blocks, fill the soil in the space prepared behind the wall, and in the soil, the reinforcement connected with the wall is embedded so that the wall is the pressure of the soil. Reinforcement earth retaining wall was constructed so that it was not pushed forward by.

However, this construction method is too big for the wall and the earth and sand itself, so there is a fear of subsidence, it is necessary to compact the soil to be backfilled, the construction is cumbersome, and if the soil is poor due to poor compaction, defects occur and must be rebuilt. There was a problem with the hassle and the air and cost accordingly. Therefore, the backfilled soil has had to use a good quality soil to be determined.

In addition, the installation of reinforcement buried in the soil is difficult, and above all, a serious problem that the wall collapses when such heavy wall and soil is submerged, and a separate drainage to prevent the loss of backfilled soil There was.

In order to solve this problem, a method for constructing mixed soil on soft ground, or a retaining wall structure construction method for reinforcing fill land, incision, etc. is disclosed in Patent Registration No. 10-0949781.

The conventional construction method, as shown in Figure 1 by using a heavy equipment in the city factory to raise the vertical column 110 at a predetermined interval, and sandwiched the outer panel 120 between the vertical column 110 in a stacked manner fence Then, the mixed soil, concrete, or the required filling soil including these were deposited in the rear filling space of the fence to strengthen the soft ground or to build the retaining wall.

Furthermore, since the vertical column 110 extends from the initial stage of construction to the construction height of the filling soil or mixed soil, the exterior panel 120 is inserted when the exterior panel 120 is inserted between the vertical pillars 110. Since the vertical holding unit 110 to be transported to the upper end and then sandwiched between the two vertical holding unit 110, the assembly of the exterior panel 120 was inconvenient, and also the vertical holding unit 110 extended from the beginning of the construction is an obstacle to other work, That is, the wire that lifts the exterior panel 120 is hooked, causing a problem of twisting, which causes the air to be further delayed.

In addition, the conventional mixed soil construction method is very difficult to install the earth pressure dispersion member 160, and the deformation and construction is complicated when compacting, which causes the construction cost and increased air.

Hereinafter, a panel according to the present invention, a fence using the panel, a method for constructing the fence, and a method for constructing a mixed soil structure using the fence will be described in detail.

First, the panel A which concerns on this invention is demonstrated.

The panel (A) is a component constituting the fence (1) to be interposed between the pillars to be described later to be fitted to be laminated so that the mixed soil to be poured before the construction of the filling structure (W) of the mixed soil to flow to the outside.

The panel A has a receiving portion A-1 for receiving the pillar at both ends. The accommodating portion A-1 is configured to have an open side outside and has a space capable of accommodating at least half the thickness of the pillar.

The shape of the accommodating part A-1 may be configured in various forms according to the cross section of the pillar to be accommodated, for example, is configured in a semi-circular shape so as to accommodate the pillar having a circular shape as shown in FIG. It may be configured in a "c" shape to accommodate a column having a square or rectangular shape as shown in 13, and may be configured in a semi-ellipse shape to accommodate a column having an elliptical shape as shown in FIG. In addition, the shape of the receiving portion (A-1) can be variously formed according to the cross section of the column to be applied.

The material of the panel (A) may be a mixture of concrete, cement and air and mixed soil, FRP, synthetic resin containing a hardener and the like.

Next, a fence according to the present invention using the panel will be described.

The fence 1 is to block the pour mixed soil when the mixed soil is poured to form the fill structure (W), it is shown in Figures 2 to 6.

The structure of the fence (1) is largely, a base (11) fastened to the anchor bolt (B) of the base concrete surface (G), a column (12) assembled on the base (11) so as to be adjustable height adjustable, And a panel A which is stacked between the blocks 12 to block the mixed soil.

The base 11 is for installing the pillar 12 on the base concrete surface (G), the connecting piece (11b) protrudes on the plate (11a).

A fastening hole 11a-1 penetrates the plate 11a so that the anchor bolt B placed on the base concrete surface G can pass therethrough. The fastening hole (11a-1) is preferably configured in the shape of a long vertical hole to selectively adjust the position of the plate (11a). The connecting piece 11b is for connecting the pillars 12 assembled in a row on top thereof, and is configured in the form of a hollow shaft or a solid shaft.

The base 11 configured as described above allows the anchor bolt B placed on the foundation concrete surface G to pass through the fastening hole 11a-1, and then tightens the anchor bolt B with a nut. It is firmly fixed to the surface G.

The column 12 is connected to the unit pillars (12a) detachably in a row in order to adjust the length, and the unit column (12a) located at the bottom is fitted to the connecting piece (11b) of the base (11).

The configuration connecting the unit columns 12a is shown in the exploded perspective view of FIG. The unit pillar 12a is formed in a hollow shape and a fitting portion 12b is formed at one end thereof, so that when the other unit pillar 12a is assembled to the fitting portion 12b, the thickness of the pillar 12 becomes the same as a whole. .

The unit columns 12a are preferably fastened with the bolts B1 by contacting the two unit columns 12a contact portions so that they are not disassembled arbitrarily in a state in which the two unit columns 12a are assembled in a row. To this end, the assembling hole 12c is formed in the lower portion of the unit pillar 12a, and the screw hole 12d is formed in the fitting portion 12b.

On the other hand, another embodiment of the configuration for connecting the unit pillar 12a is shown in FIG. The two unit columns 12a are connected to the coupling 12c, and the assembling holes 12c- of the coupling 12c are inserted in a state in which both unit columns 12a are inserted into the coupling 12c and closely connected to each other. 1) and the screw holes (12d) of the unit pillar (12a) to match them with a bolt to assemble the two unit columns (12a) in a row bound in a row.

In addition, in the method of connecting the unit columns 12a, a portion where the two pillars 12 contact each other may be fixed by welding, pressure welding, or the like.

In this way, when two or more unit columns 12a are connected in a line and the lowermost unit columns 12a are assembled to the base 11, the pillars 12 are assembled, and the panels between the assembled pillars 12 are provided. Laminating (A) completes the fence (1), the height of the fence (1) will vary depending on the number of unit columns (12a) used, so at the beginning of construction only the position corresponding to the height of the light mixed soil or mixed soil placing It is preferable that the column 12 is not too high by using the unit columns 12a.

That is, at the initial stage of construction, 1-2 unit columns 12a are assembled to the base 11 disposed on the foundation concrete surface G so that the pillars 12 are not high, and in this state, between the pillars 12. After assembling the panel (A) to form a fence (1), the lightweight mixed soil or mixed soil is poured in the space prepared behind the fence (1). When the height of the column 12 decreases due to the mixing soil pouring, the other unit pillars 12a are reassembled in a row on the upper portion of the pillar 12 to raise the column 12 to pour light mixed soil or mixed soil into the space located behind the pillar 12. Placing the mixed soil by the method, as well as the pillar 12 does not interfere with the construction work, it is possible to easily assemble the panel (A) between the pillar (12).

The final height position of the pillar 12 can be selectively adjusted to suit the site's requirements, for example, it can be used to protrude beyond the top of the mixed soil and use this protruding portion as the handrail 3. This can solve the hassle of forming a railing by putting a file separately, which has the effect of two stones.

As described above, the panel A forming the fence 1 has an accommodating portion A-1 for accommodating the pillars 12 on both sides thereof. On the back of the panel (A), the reinforcement 13 is detachably assembled to be embedded in the mixed soil to be poured or the filled soil to be filled.

The panel (A) is a bracket (A-2) having a hook (A-21) protrudes on the back so as to rotatably connect the reinforcement (13).

The reinforcement 13 is preferably lightly configured to rise by buoyancy, and may be formed in a rod-like or plate-like shape in the form of a hollow, and various other shapes. In addition, the reinforcing material 13 may be configured to be smooth as well as a plurality of protrusions (13a) protruding from the surface as shown in Figure 7 to 9 as another embodiment, the end portion is to be assembled to the hook (A-21) The hole 13b is penetrated so that it can be. The protrusion 13a of the reinforcing material 13 is a stopper function so that the reinforcing material 13 does not fall out when the mixed soil is cured to form the fill structure W. As a result, the panel A is filled by the reinforcing material 13. It is firmly fixed to the structure (W).

The angle of rotation of the reinforcement 13 is possible by the adjustment bolt 14 fastened to the bracket A-2. That is, as shown in FIG. 9, when the mixed soil is poured into the installation space, the reinforcing material 13 rotatably mounted on the rear surface of the panel A is raised by buoyancy as the height of the mixed soil increases. The free end rotates ascends the hook A-21 of (A-2). Since the rotating reinforcement 13 is preferably disposed at right angles to the panel A, the reinforcement 13 is at right angles to the panel A by adjusting the adjustment bolt 14. Of course, the reinforcement 13 may be adjusted to be acute or obtuse with respect to the panel A by adjusting the locking degree of the adjustment bolt 14. This can be selected by the user according to the situation of the site.

Depending on the configuration of the reinforcing material 13, the reinforcing material 13 may be manufactured in various forms, and any type of thing may be applied as long as it can freely float by buoyancy.

Next, a method of constructing the fence 1 according to the present invention will be described.

In the method of constructing the fence (1) according to the present invention, after leaving the plurality of anchor bolts (B) on the foundation concrete surface (G), the foundation concrete surface (G) is exposed to expose the upper portion of the anchor bolt (B). Pouring;

Fitting and fixing the base 11 constituting the base of the pillar 12 to each of the anchor bolts B;

Selectively adjusting the height of the pillars 12 by connecting unit pillars 12a in a row on top of each base 11 plate to match the placing height of the mixed soil; And

And inserting and stacking a plurality of panels A between the assembled pillars 12 so that the pillars 12 are not exposed.

The step of placing the foundation concrete surface (G) in the fence (1) construction method can be carried out in the field by placing the anchor bolt (B) first on the bottom of the installation place and then placing the foundation concrete surface (G).

Alternatively, it can be replaced with a precast product without placing the foundation concrete surface (G) in the field, depending on the situation where the concrete curing takes much time in the winter season or the requirements of the site. In other words, the precast product molded in the manufacturing plant can be used deeply embedded in the installation place.

The precast product may fasten and fix the base 11 because the fastening part is exposed while the anchor bolt B is embedded therein.

Since each anchor bolt B is arranged in a line in order to install the pillar 12 for stacking the panel A on each of the foundation concrete surfaces G or precast products, the anchor bolt B is When the nut is fastened to the anchor bolt B while the base 11 is placed on the base concrete surface G or precast by passing the fastening hole 11a-1 of the base 11, a plurality of bases are provided. (11) can be fixed in a line at regular intervals.

When the assembly of the base 11 is completed as described above, the pillars 12 are assembled by connecting and assembling the unit columns 12a in a line to the connecting pieces 11b of the base 11.

That is, the connecting piece 11b protrudes from the base concrete surface G or each base 11 fixed to the precast. Unit columns 12a are connected to the connection piece 11b in a row. At this time, the height of the column 12 is selectively adjusted by adjusting the quantity of the unit pillar 12a while going in accordance with the pouring height of the mixed soil.

The assembly of the unit pillar 12a is to insert the unit pillar 12a to the connecting piece 11b of the base 11, as shown in Figure 5, and then the other unit pillar to the fitting portion 12b of the unit pillar 12a The plurality of unit columns 12a are connected in a line by inserting the lower end of the 12a. The unit columns 12a are not disassembled by matching the assembly holes 12c and the screw holes 12d so that the respective unit columns 12a are not separated from each other, and then inserting the bolt B1 and fastening them to the screw holes 12d. Thus, the assembly of the pillar 12 is completed.

Since the pillar 12 is for firmly stacking the panel A in the horizontal and vertical directions, if the pillar 12 is too high in the initial panel A assembly process, the panel A is lifted by that much and then the both ends are accommodated. It is inconvenient to assemble the panel A because the pillar 12 must be inserted into the portion A-1.

Therefore, in the present invention, when assembling the fence 1, the column 12 is composed of the connection of the unit columns 12a, so that the height of the upper end of the column 12 is placed in the place where the mixed soil is placed to simplify the panel A assembly. In accordance with the above, it is preferable to determine a little higher than the pouring height of the mixed soil.

When the pillar 12 is assembled in such a manner as to gradually increase the height of the pillar 12 in accordance with the pouring height of the mixed soil as described above, the panel A is assembled to the pillar 12 in a stacked manner, and the height of the mixed soil is mixed. Assemble up to the casting height of. The method of assembling the panel (A) is to lift the plurality of panels (A) to the height of the column (12) as shown in Figs. ) Is placed on the base concrete surface (G) or on the precast article, and then another panel (A) is laminated on top of the positioned panel (A) in the same way. At this time, the panels A adjacent to the side are in close contact with each other, so as to surround the pillars 12 as shown in FIGS. 12 to 14, the pillars 12 are embedded in the panel A so as not to be exposed.

In this way, when the plurality of panels A are assembled in a row and stacked in the upward direction, the assembly of the fence 1 of the present invention is completed, and the pillars 12 and the panel A constituting the fence 1 are completed. When it is gradually increased in accordance with the pouring height of the mixed soil, it is easy to assemble the columns 12 and the panel A, but since the pillars 12 and the panel A are not too high, they do not interfere with the pouring of the mixed soil. It is convenient and has the effect of shortening the air.

On the other hand, the mixed soil fill structure construction method according to the invention when the assembly of the fence (1) is completed as described above, the step of pouring the mixed soil in the space behind the fence (1); proceeds to include.

That is, after allowing the plurality of anchor bolts B to be spaced apart from the foundation concrete surface G, placing the foundation concrete surface G to expose the upper portion of the anchor bolt B;

Fitting and fixing the base 11 plates constituting the base of the pillar 12 to the anchor bolts B;

Selectively adjusting the height of the pillars 12 by connecting unit pillars 12a in a row on top of each base 11 plate to match the placing height of the mixed soil;

Inserting and stacking a plurality of panels (A) between the assembled pillars (12) to form a fence (1) by embedding the pillars (12) so as not to be exposed; And

And placing mixed soil on the rear space of the fence (1).

Each of the above steps has already been described in detail in the fence (1) construction step will be omitted.

In addition, the mixed soil structure construction method of the present invention further comprises the step of rotatably mounting the reinforcing material 13 on the back of the panel (A) forming the fence (1).

Since the configuration of the reinforcing material 13 has already been described, a detailed description of the configuration will be omitted.

Since the reinforcing material 13 is rotatably mounted on the rear surface of the panel A, when the mixed soil is poured, as the height of the mixed soil rises, it is raised by buoyancy so that the free end is rotated around the hole 13b. When the panel A is stopped to be disposed at a right angle to the panel A, the panel A is firmly fixed since it is embedded in the cured mixed soil and connects the panel A with the fill structure W.

The step of pouring the mixed soil is to prevent the large pressure is applied to the fence (1) by the pour mixed soil and to pour the mixed soil to the height of about 1M so as to cure quickly and then cured again on it The fill structure (W) is constructed by pouring the same height.

Therefore, since the fence 1 is cured sequentially in units of 1M height, the fence 1 does not have a large pressure when placing the mixed soil.

In this way, since the mixed soil is poured sequentially at a height of about 1M for a predetermined time, the fence 1 to be constructed beforehand is also sequentially stacked by the height that can accommodate the mixed soil so that the fence 1 is too high to obstruct the construction. Do not become.

The mixed soil structure construction method is shown sequentially in Figures 15a to 15j.

The fence (1) of the present invention constructed as described above is assembled to fit the panel (A) and the panel (A) is fixed to the pillar 12, so that the self-reliance is very firm and construct a fill structure (W) of about 10M or more It is preferable to apply when constructing.

The present invention constructed and constructed as described above is a problem of the conventional retaining wall structure construction method, that is, the problem of having to vertically install the vertical column 110 to at least the fill height of the mixed soil, the problem of using a large heavy equipment anti-taking, and the pillar is exposed. It is a beneficial invention that can solve the problem that the pillars are corroded without the beautiful decoration of the outer wall, the air delay caused by these problems at a glance.
