It is preferable that the first casing and the second casing can be arranged side by side without any gap while making surface contact with the contact portion in the form of the flat portion 102a.

In addition, as shown in Fig. 21, when the hang-glove (H) is put into the casing, the flat portion (102a) is a hang-glove (H) to prevent the hang-g (H) to rotate or move in the casing It will support the side of. As seen from the bottom, as shown in (b), the row glove (H) can be spread apart so that there is almost no gap in the casing, there is an advantage to take out the ground material of the bottom without missing.

22 and 23 are diagrams illustrating the grouting method of the present invention. Referring to FIG. 22, when the casing scrapes down the ground, ground material is accumulated at the bottom as A. FIG. The ground must be taken out and removed or grouted with a cement mixture such as mortar, such as mortar. If not, groundwater can lead to groundwater leakage or breakage.

Since the cement mixture should be sprayed on the lower end of the casing, it is preferable to insert an input member such as a pipe P into the ground and spray it toward the lower end of the casing. The injection member is preferably injected into the lower end of the casing as close as possible, and in this case, as shown in FIG. 23, the cement mixture C is spread, and the lower end of the casing is grouted. The ground material A of the casing lower end may be hardened by the grouting of the cement mixture C, or in some cases, may be pushed upward by the cement mixture C.

27 is a diagram illustrating various embodiments in which the casing of the present invention is disposed. Referring to FIG. 27, the casing shown in FIG. 26 is shown in a plan view. The opening 110 may be continuously arranged to contact other casings as shown in (a), and the opening may be performed as shown in (b). It may be arranged so that a slight gap occurs between the part 110 and the other casing. In addition, as shown in (c), the protrusion 116 protruding from the opening 110 may be disposed to be in contact with or in proximity to another casing.

The opening 110 provides a path that allows the cement mixture or the like introduced into the casing to be in contact with, connected to or integrated with the other casing on the side. For example, when the cement mixture is introduced into the two casings 100 and hardened to some extent after a predetermined time, the cement mixtures located in the two casings 100 are in contact with each other when the casing 100 is shaken out. It can be cured and integrated at the same time.

28 is a diagram illustrating various embodiments in which another casing of the present invention is disposed. Referring to FIG. 28, the shapes of the casing 100 and the opening 110 may be variously combined to form a deformed shape, a diamond shape, or the like. In this case, the effects and actions are the same.

FIG. 29 is a diagram illustrating an embodiment in which the casing of FIG. 20 is modified. Referring to FIG. 29, in the case of the casing having the contact portion described with reference to FIG. 20, the connectors 120 and 190 slidable in the vertical direction in a rail manner are disposed on both sides in a contact portion that looks like a portion of a circular edge is cut out.

Referring to FIG. 30, as indicated by H, a plurality of casings 100 are lodged in the spaces between which steel is embedded, while the casing 100 is lowered by the above-described method while scraping the ground and lowering the ground material ( A) is accumulated or, in some cases, soil, sand (B), etc. are accumulated in the lower side, or the casing 100 can not be inserted into the strong rock ground (G) for economic reasons and construction reasons.

In this case, ground material, soil, sand, etc. are left below the casing 100, and if left as they are, this part is weakened or collapsed after completion of construction, so that the wall of the wall is damaged or leaks may occur. do. Therefore, until the section reaching the rock foundation (G) does not collapse, it must be cured through a cement mixture or the like to form a wall. By the way, the ground material, soil, sand and the like remaining portion of the cement mixture is not introduced, even if introduced there is a problem that is not hard and sufficiently hardened.

In order to solve this problem, the stirrer (S) is introduced into the casing 100, the stirrer (S) is inserted into the lower side of the casing 100 as well as the lower end of the casing 100, the ground material Stir the soil, sand, etc. When the stirrer S is stirred or before and after the stirring, when stirring materials such as cement mixture and soil cement are introduced and stirred together, the cement mixture is immediately above the ground G, and the position at which the stirrer S is stirred. It is evenly mixed until, and when cement hardens, the whole is hardened evenly to form a solid soil wall. This will be described sequentially.

31 is a view showing a procedure in which the stirrer is put into the casing of the present invention and operated. Referring to FIG. 31, the ground material A remaining or scraped down during the excavation remains on the upper side of the solid foundation ground G, and the stirrer S is inserted and lowered to lower the ground material ( A) and the soft ground below it are stirred (b). After this, when the stirrer S is further lowered and the cement mixture C is introduced at the same time of stirring or before and after stirring, the casing 100 functions as a large container, and the ground material A inside thereof is Cement mixture (C) is mixed evenly (c).

After taking out the stirrer (S), when the cement mixture is continuously introduced, the inside of the casing is hardened while maintaining the overall uniformly mixed state, and the entire earth wall is free of empty space above the solid ground (G). Is formed. Therefore, by using a stirring apparatus, the soil located in the gap between the remaining soil, ground material, crushed soil, and the excavation hole evenly mixed with the cement mixture, and then completely hardened the whole, so that the soft part such as soil is the wall of the wall It is to prevent remaining in the middle of the water, and to prevent water leakage or wall collapse.

After stirring, it is preferable to insert the support member 200, such as reinforcing bar, into the casing 100 to cure together. In addition, after the curing is progressed for a certain time, if the casing is removed sequentially or at a time, since the cement mixture in each of the casing is hardened by contact with each other, so as to form an integral mud wall so that no separate grouting is necessary.

In some cases, it is also possible to install the next casing side by side and cure sequentially, while removing the casing during or after curing while curing the first installed casing.

It is a figure which shows the state in which the casing of this invention is installed. Referring to Figure 32, the steel frame, such as H beam (H) is inserted after the plate to the rock layer (G), the casing portion connecting between the excavation is excavated only to the soil layer (B). Soil layer (B) inside the casing and ground material such as ground debris, gravel, sand, soil, etc. are agitated and hardened by a stirrer, and supporting members such as reinforcing bars, lath nets, and wire nets are preferably integrated inside the casing. Do. The casing is arranged to be close to each other through the concave portion, in this case has the disadvantage of increasing the number of excavation work, but there is an advantage that it is possible to form a seamless, integrated earth wall in one construction.

In some cases, when the H-beam and cement mixture is placed inside the previous casing, or when only the reinforcing bar and the cement mixture are cured without the H-beam, the cement mixture is cured, or the casing is removed at the stage of hardening. The next casing, either before or after, may be inserted while opening towards the cement column being cured or cured. The cement casing is also introduced into the next casing, contacting the already hardened cement column, and subsequently forming the next column. The drawings may be sequentially installed in a left to right direction, or may be sequentially installed in a right to left direction.

Fig. 33 is a diagram showing another embodiment of the casing of the present invention, and Fig. 34 is a diagram showing the movement of the casing. Referring to FIG. 33, a casing 200 is formed by gathering a plurality of side wall portions 210, and connected between the side wall portions 210 by a joint portion 220, and hinged so that the side wall portions 210 rotate with each other. Play a role. Two or more side wall portions 210 may be connected to the joint portion 220.

Joint portions 220 are connected between the side wall portions 210, but the pair of side wall portions 210 are left open without being connected to the joint portion 220 as shown in the drawing. According to the rotation caused by the joint part 220, the side wall parts 210 may be close to each other, and may be retracted or moved away from each other.

Referring to FIG. 34, the casing 200 having a large inner area is partially opened as shown in (a), and as shown in (b), the inner area or the inner diameter is reduced. As the inner diameter can be increased or decreased, the casing can be more easily inserted into the excavation hole.

Referring to FIGS. 35 and 36, when the excavation hole is excavated with an auger, the circular shape is initially maintained as D, and the sidewall is collapsed, and the diameter decreases inward as d is collapsed.

Since the casing that fits the original drilling radius is somewhat difficult to be inserted into the drilling hole, the casing 200 having the joint portion can be easily inserted in a state of being slightly retracted with an inner diameter smaller than d.

After that, while opening the side wall portion 210 of the casing 200 to the outside, the support 230 is inserted into the inside so that the side wall portion 210 is pushed outward as much as possible. Support 230 is preferably to have a wedge shape of the inner diameter of the lower side is large, the inner diameter of the upper side to facilitate insertion. As the support 230 is provided, it is possible to secure the widest space in the excavation hole, and when the casing 200 is removed simultaneously with the hardening of the cement mixture introduced therein, the casing 200 is crushed, It will prevent invasion of the curing space of the cement mixture.

At this time, in the state where the inner diameter is sufficiently secured by the casing 200, the cement mixture such as concrete may be introduced into the interior, and the support 230 or the casing 200 may be removed during the curing process. On the other hand, the casing 200 can be supported without retracting inward by the external force through the protrusion 212 formed at the bottom in addition to the support 230, the protrusion 212 is on the ground when the casing 200 is inserted While being stuck, serves to maintain the position of the side wall portion 210 firmly.

Referring to FIG. 38, the first casing 300 and the second casing 300 are brought into close contact with each other to be inserted into an excavation hole (not shown). In this case, the opening of the first inner casing 320 is disposed toward the contact portion, and the opening of the second inner casing 320 is disposed on the opposite side of the contact portion. That is, the opening of the first inner casing 320 is fitted toward the opposite side of the opening of the second inner casing 320.

In the second casing 300, the ground material remaining in the gap between the excavation holes is cut down by the downward pressure of the second casing 300, and the ground material accumulated by cutting the inside of the ground material is described in the embodiment of the present invention. As described above, the stirrer is introduced to cause the stirrer to stir the second casing 300. While the stirrer is stirring or before and after stirring, a stirrer such as a cement mixture is introduced to mix the cement mixture evenly with the ground material. In some cases, the stirring process may be omitted and only the stirring material may be introduced.

The inside of the casing is hardened while maintaining the overall uniform mixing state. Here, after curing has been performed for a certain period of time, when the outer casing 310 is sequentially or temporarily removed, the cement mixture comes into contact with each inner casing 320, and when the inner casing 320 is removed again, Stirring materials such as cement mixtures come into contact with each other through a tool to be integrated to form an earthen wall. In addition, it is also possible to remove the outer casing 310 as soon as the inner casing 320 is installed before the stirring material is added.

In some cases, it is also possible to install the following casings side by side while curing the casing first installed while removing the casing during or after curing, and to cure sequentially. The inner and outer casings can be inserted at the same time as the excavation, and when removed, they can be removed sequentially or temporarily.

In addition, after inserting the first outer casing and the first inner casing, the first outer casing may be first drawn out, immediately inserted into the second drilling hole, and the second inner casing may be inserted therein. The outer casing is to prevent the inner casing, which is partially open, from being deformed, deformed, or broken by the surrounding pressure. The outer casing can be withdrawn immediately after the inner casing is installed. Even in the case of the inner casing, it is possible to withdraw the stirring material such as mortar, concrete, or cement mixture even before it is cured, and when the other outer casing or the inner casing arranged at the side is also drawn out simultaneously or slightly later, the stirring materials are connected to each other. And it is cured, it is possible to form the wall completely, without additional work such as a separate grouting operation.
