Description

Temporary structure and construction method of temporary facility structure and construction method using square pipes {STRUCTURE OF COFFERDAM USING SQUARE PIPE AND　CONSTRUCTION METHOD}

The present invention relates to a temporary facility structure using a square tube, and more particularly, to a temporary facility structure and a temporary facility structure using a square tube in cross section.

Temporary film is a facility temporarily installed to prevent water or soil at a construction site, and it is generally constructed by drilling or driving an H-beam, cylindrical pile, or sheet pile.

1 is a block diagram of a conventional temporary facility structure for preventing soil and sand. Referring to FIG. 1, in the related art, a sheet pile (1) installed on the outer periphery, a strip (2) horizontally installed on the sheet pile (1), a strut (3) connected vertically on the same plane as the strip (2), It consists of a center pile (4) installed perpendicular to the ground surface.

However, since such a conventional temporary facility structure uses the sheet pile 1, the rigidity is insufficient, and members such as the strip 2, the strut 3 and the center pile 4 are additionally required to reinforce the insufficient rigidity, Since it is affected by side pressure depending on the depth, there is a problem that as the depth increases, more band lengths (2), struts (3), and center piles (4) are required.

In addition, in the conventional temporary facility structure, it is difficult to secure a sufficient working space due to the additionally installed strip (2), strut (3) and center pile (4), the constructability is not good, and it is difficult to shorten the construction period, which is economically expensive. There is this.

In addition, there is Korean Patent Registration No. 10-1022841 (name of the invention: temporary barrier using corrugated steel or bent steel) as a conventional temporary barrier-related patent. In the case of a single sheet pile wall installed in one row, the wall Due to its weak rigidity, it is easy to deform the wall due to lateral pressure, and there is a problem that a separate support method must be performed in parallel using a support material.

To solve this problem, a two-row sheet pile wall is used in areas with high side pressure.The two-row ordered tentacle wall is driven by driving the sheet pile into two rows, and is mainly used as a barrier material in the space between the two rows of sheet piles. ) Or sand is used as a barrier material (filling material), and tie cables are tied up and down at regular intervals in order to prevent the spreading or bloating of both walls due to the load of the soil when the high quality soil is dropped. By supporting the sheet pile wall to prevent deformation and spreading is mainly used.

However, in the existing tie cable construction method, most of the temporary barriers are installed underwater or underground at regular intervals, so in the case of underwater, an underwater work must be performed using a diver, and the wall section adjacent to the underground is practically any support device. There are various problems because it cannot be done.

In order to solve this problem, the technology of Korean Patent Registration No. 10-1859440 (name of the invention: a complex river facility construction method using a means for connecting temporary walls) is proposed, but this technology also uses sheet piles, so the filling space There is an inconvenience of construction that must be filled with a filler.

In order to solve this inconvenience, it is possible to construct a temporary barrier by using a plurality of cylindrical piles, but since the cylindrical pile is produced through a process of rolling a plate, there is a problem that its thickness is limited, and the side pressure is There is a problem of insufficient rigidity in a high area.

If a rectangular square tube of such a structure is used, a structure of a rectangular shape of a temporary mask as shown in FIG. 4 can be completed.

The temporary facility structure using a square pipe according to an embodiment of the present invention has various advantages compared to the prior art, and one of them has the advantage of being able to construct even in areas with high side pressure.

Conventionally, two-row sheet pile walls are used in areas with high lateral pressure.The two-row ordered temporary barrier wall is driven by driving the sheet pile in two rows, and it is mainly used as an insulating material in the space between the two rows of sheet piles. Sand is used as a barrier material (filling material). In this case, tie cables are supported by tying up and down at regular intervals in order to prevent the spreading or bloating of both walls caused by the load of the soil when the internal high-quality soil is dropped. As a result, a technique for preventing deformation and spreading of the sheet pile wall was mainly used.

However, the temporary facility structure using a square pipe according to an embodiment of the present invention is constructed by a combination of a plurality of square square pipes, and at this time, each wall can be seen as having two rows of plates arranged. Silver sheet piles can achieve the same effect as arranged in two rows.

That is, the temporary facility structure using a square pipe according to an embodiment of the present invention has the advantage of being able to prevent deformation and spreading of the wall without using a tie cable or strip.

In addition, in the temporary facility structure using different angle pipes according to an embodiment of the present invention, a coupling protrusion formed in each of a plurality of square square pipes is fitted into a corresponding coupling groove, wherein the coupling groove is itself joined. Since it serves as a guide for construction, convenience in construction is increased, and the rigidity of the entire structure can be improved by maintaining a rigid connection structure after bonding.

And a plurality of square square pipes according to an embodiment of the present invention may be joined by welding of four flat plates.

As one of the techniques for constructing a conventional temporary barrier structure, there is a method of constructing a temporary barrier using a plurality of cylindrical piles, but since the cylindrical pile is manufactured through the process of rolling a plate, there is a limitation in its thickness. There is a problem.

Specifically, since the cylindrical pile of the plate is manufactured through the process of rolling the plate and processing, the diameter of the entire cylindrical pile is inevitably affected by the thickness of the plate. That is, the diameter of the entire cylindrical pile and the thickness of the plate are in proportion to each other. Therefore, the thickness of the plate is affected by the diameter of the entire cylindrical pile.

For example, in the case of constructing a temporary barrier structure using a cylindrical pile in an area with high side pressure, it is necessary to secure a high support force by the high side pressure, and the thickness of the plate material needs to be thick to secure a high support force. However, when the thickness of the plate becomes thick, the diameter of the entire cylindrical pile increases, making construction difficult, and the wall of the temporary barrier structure becomes thicker than necessary, resulting in a problem that the space secured inside may be rather small.

However, the temporary facility structure using a square pipe according to an embodiment of the present invention uses a plurality of square square pipes, and the plurality of square square pipes are joined by welding of four flat plates. This makes it possible to increase the thickness of the plate material while maintaining the entire width of the rectangular square tube (corresponding to the diameter of the cylindrical pile).

Therefore, the temporary facility structure using a square pipe according to an embodiment of the present invention solves the above problems and is much more convenient to construct than using a conventional cylindrical pile in an area with high side pressure, while the interior of the temporary structure You can secure enough space.

5 to 7 are diagrams showing another coupling structure of a temporary facility structure using a square pipe according to an embodiment of the present invention.

Referring to FIG. 5, the temporary facility structure using a square pipe according to an embodiment of the present invention includes a first rectangular square pipe 510, which is one of a plurality of square square pipes 510, 520, 530, in a length direction. The coupling protrusion 511 is formed accordingly, and the second rectangular square pipe 520, which is one of the plurality of rectangular square pipes 510, 520, 530, has a coupling groove 522 along the length direction so that the coupling protrusion 511 is inserted. When formed, the cross section of the coupling protrusion 511 of the first rectangular square tube 510 is formed in a T-shape, and the coupling groove 522 of the second square square pipe 520 is formed to correspond to the coupling protrusion 511 Can be.

In the case of FIG. 5, the support force between the first square pipe and the second square pipe may be further improved than that of FIG. 2.

Referring to Figure 6, the temporary facility structure using a square pipe according to an embodiment of the present invention is a first rectangular square pipe 610, which is one of a plurality of square square pipes 610, 620, 630, has a length direction. The coupling protrusion 611 is formed accordingly, and the second rectangular square pipe 620, which is one of the plurality of square square pipes 610, 620, 630, has a coupling groove 622 along the length direction so that the coupling protrusion 611 is inserted. When formed, the cross-section of the coupling protrusion 611 of the first rectangular square pipe 610 is formed in a trapezoidal shape, and the coupling groove 622 of the second square square pipe 620 is formed to correspond to the coupling protrusion 611 I can.

In the case of FIG. 5, the support force between the first square pipe and the second square pipe may be further improved than that of FIG. 2.

In addition, in the case of FIG. 5, since the coupling protrusion 511 is formed in a T-shape, there is a fear that the coupling protrusion 511 may be deformed or damaged due to the concentration of stress on the neck of T. In contrast, in the case of FIG. 6, the stress may be concentrated on the side with a shorter side length than on the side with a longer side in the coupling protrusion 611 having a trapezoidal shape. In this case, the coupling protrusion 611 and the first rectangular square tube Since the bonding area (bonding area) between the 610 is wider, the possibility that the bonding protrusion 611 is deformed or damaged is significantly reduced compared to FIG. 4 even when the stress is concentrated.

That is, in the case of FIG. 6, while the supporting force between the first square pipe 610 and the second square pipe 620 is further improved, there is an advantage that there is little possibility of deformation or damage of the coupling protrusion 611.

Referring to FIG. 7, the temporary facility structure using a square pipe according to an embodiment of the present invention may have a different coupling structure.

For example, as shown in Fig. 7(A), the cross section of the coupling protrusion 711a of the first square pipe 710a is formed in a step shape, and the coupling protrusion 721a of the second square square pipe 720a is thus It may be formed to correspond to form a coupling structure.
