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

As shown in Figures 2 to 8, the present invention is basically a soil structure, in order to prevent the side collapse of the pit soil formed by the excavation of the ground 100, a plurality of pile (102A) is continuously It relates to a continuous wall guide 110 for guiding the construction of the connected continuous wall (102).

That is, the continuous wall guide 110 may include a plurality of guide parts 120 that are separated from each other along at least the circumferential direction of the continuous wall 102 and are combined with each other to form the continuous wall forming space 112.

Therefore, by forming the perforations for the construction of the continuous wall 102 vertically and accurately at the correct position by the continuous wall guide 110, the continuous wall 102 can be accurately constructed without any error, and thus the continuous wall The effect that the gap is prevented from forming in 102 can be obtained.

In addition, by the continuous wall guide 110, it is possible to obtain the effect that the drilling for the construction of the continuous wall 102 and the placing of the continuous wall 102 can be easily and quickly proceeded.

In particular, the plurality of guide parts 120 may be a member for the straight part for forming the straight part of the continuous wall 102 so that the continuous wall 102 can easily guide the construction of the continuous wall 102 in any shape. 122 and corner members 124 for forming corner portions of the continuous wall 102 are preferably configured.

Each of the linear member 122 and the corner member 124 is spaced apart along the thickness direction of the continuous wall 102 as the plurality of guide portions 120 are separated from each other along the circumferential direction of the continuous wall 102. The inner and outer panels 122A and 124A (122B and 124B) may be installed.

The inner and outer panels 122A and 124A (122B and 124B) of the linear member 122 and the corner member 124 may be formed in various ways, respectively, and in particular, the outer surface thereof is formed in a plane. By doing so, even after the installation of the continuous wall guide 110, the naked eye can easily take advantage of being able to confirm whether or not the accurate installation of the continuous wall guide 110.

That is, if there is no step or gap between the straight member 122 and the corner member 124, the continuous wall guide 110 is installed correctly. Otherwise, at least a part of the continuous wall guide 110 is not accurate. It is not installed.

The linear member 122 may have various shapes as the inner and outer panels 122A, 124A, 122B, and 124B need, and in particular, the linear member 122 may be quickly and without confusion. It is more preferable to take the same shape so that it can be easily installed.

The plurality of guide parts 120 may be divided in various ways along the circumferential direction of the continuous wall 102. In particular, as illustrated, the plurality of guide parts 120 may be formed to be divided so as to correspond one-to-one with the plurality of piles 102A. Of course, in addition to this, the plurality of guide parts 120 may be divided to form one continuous wall forming space 112 by two or more guide parts 120, or by one guide part 120. It may be divided to form two or more continuous wall forming spaces 112.

In addition, each guide portion 120, that is, each panel (122A, 124A) (122B, 124B) is formed in a hollow structure to reduce the manufacturing cost and weight, in particular by taking a hollow penetrating in the vertical direction As described later, a key insertion of the panel connection unit 140 may be performed, and thus, the panel connection unit 140 may be simply configured.

Accordingly, by the binding unit 130, the plurality of guide units 120 may restrict each other, thereby preventing a construction error between the plurality of guide units 120, thereby preventing the plurality of guide units 120. The construction can be accurately performed, and therefore, the effect that the workability of the continuous wall 102 is excellent can be obtained.

In addition, since the plurality of guide parts 120 serve as mutual support, separate work or members for installing and fixing the plurality of guide parts 120 may be omitted, thereby rapidly providing the continuous wall guide 110. It can be installed and the cost can be reduced.

To this end, the binding unit 130 may have any configuration as long as the plurality of guide units 120 can be detachably connected to each other, and in particular, the adjacent guide units 120 may be adjacent to each other along the circumferential direction of the continuous wall 102. It may include a panel connector 140 for connecting.

As shown in the drawing, the panel connection part 140 includes a ring member 142 provided on one side of each guide part 120 and having at least one ring 142A fitted to neighboring guide parts 120.

The ring member 142 may be formed as a closed ring as shown, and may have a shape in which a part is opened, such as a hook, as necessary.

The key 144 may have a pin structure as shown, and any configuration may be provided as long as it can be detachably fitted to a neighboring ring member 142 as necessary.

As described above, the loop member 142 and the panel connection portion 140 having the key structure may be easily configured by forming the guide member 120 in a hollow shape vertically penetrating as described above.

In addition, the panel connection unit 140 is simple in one operation by inserting a key into the ring member 142 as compared with the case of connecting two adjacent guide units 120 using a bolt, a welding method, or the like. It can be finished, and since the two adjacent guide portion 120 can be easily separated when removing the guide 110 for the continuous wall, it is more effective.

And, as described above, the binding unit 130 has a structure in which each guide unit 120 is separated into inner and outer panels, and the inner and outer sides of the guide units 120 along the thickness direction of the continuous wall 102.

Can be configured.

Since the gap maintaining panel 152 only needs to maintain a gap between the inner and outer panels of each guide part 120, the gap maintaining panel 152 is formed like a panel as shown, rather than being formed to fill the continuous wall forming space 112. It may be more preferable.

The gap maintaining panel 152 may be formed to have the same length as the length of the plurality of guide parts 120 in the up and down direction as shown, and may be formed shorter than the length of the plurality of guide parts 120 as necessary. It may be formed longer.

As shown in the drawing, only one space keeping panel 152 may be installed between the inner and outer panels of each guide unit 120. If necessary, a plurality of interval maintaining panels 152 may be installed in the vertical direction or along the circumferential direction of the continuous wall 102. It may be provided in plurality.

The gap maintaining panel 152 may also have a hollow structure, such as the respective guide parts 120 described above, in order to reduce the manufacturing cost and weight, if the thickness of the gap maintaining panel 152 is reduced.

The coupling member 154 may be composed of a ring 154A and a key 154B, like the panel connection unit 140 described above.

At this time, the ring 154A of the coupling member 154 is integrally formed with the spacer panel 152 as shown, and the ring 154A of the coupling member 154 on the inner side of each guide portion 120. Ring hole (hereinafter, referred to as 'inner ring hole 120C' for convenience of description) may be formed. In this case, since the construction material of the continuous wall 102 may flow into the inner space of each guide unit 120 through the inner side ring hole 120C during the construction of the continuous wall 102, the continuous wall 102. At the time of construction, the inner ring hole 120C of each guide unit 120 may be covered.

Alternatively, as illustrated in FIG. 10, a ring 154A of the coupling member 154 may be formed in each guide unit 120, and a ring hole 152A may be formed in the spacer panel 152.

At this time, the ring 154A of the coupling member 154 may be formed integrally with each of the guide portions 120, in this case, buried in the continuous wall 102 during the construction of the continuous wall 102, the guide portion ( 120 may be impossible to remove. Therefore, as shown in Figure 10, the ring 154A of the coupling member 154 is preferably configured to be separated from each guide portion 120 as a separate ring member. That is, a ring detachable hole 120D may be formed on the inner surface of each guide unit 120 for detachment of the ring 142A of the coupling member 154.

Furthermore, as described above, when the ring 154A of the coupling member 154 is pulled out during the construction of the continuous wall 102, the respective guides to cover the ring detachable holes 120D of the respective guide parts 120 are covered. It may further include an inner side cover member 162 that can be detachably installed in the portion 120.

On the other hand, as shown in FIG. 11, the panel connection part 140 may be fitted in the vertical direction to the key groove 120E formed in each of the guide parts 120 so as to span the neighboring guide parts 120 at the same time. It may include a key (hereinafter referred to as 'second key 146' for convenience of description).

At this time, the second key 146 is preferably formed to be fitted only in the vertical direction to the key groove 120E, such as a butterfly shape to prevent the gap between the two adjacent guide portion 120.

Of course, the coupling member 154 of the gap maintaining unit 150 may also be configured like the panel connection unit 140 shown in FIG.

Alternatively, as shown in FIG. 12, the panel connection part 140 may protrude on one side of each guide part 120 to be fitted in the vertical direction to the key groove 120F formed in the neighboring guide part 120. Key (hereinafter, referred to as 'third key 148' for convenience of description).
