As shown in FIG. 10 or less, the present invention relates to a temporary structure for temporary curtain for reinforcing the plurality of sheet piles 10 coupled to each other to be maintained in a predetermined shape, the support structure 100 is installed in the core; A plurality of support piles 200 installed to be spaced apart from each other around the outer side of the support structure 100; It is configured to include; a plurality of the sheet pile 10 is installed so as to be respectively closed in the area between the plurality of support piles (200).

Construction method of the temporary structure according to the present invention is as follows.

The support structure 100 is installed in water (FIGS. 14 and 15), and the plurality of support piles 200 are installed to be spaced apart from each other around the outside of the support structure 100 (FIG. 16).

A plurality of sheet piles 10 are installed in the area between the plurality of supporting piles 200, respectively (FIGS. 10 and 17).

Here, the support structure 100 corresponds to the temporary structure (Template) described above, in order to solve the difficulty of proceeding with the sheet pile assembly in the water, a plurality of support piles 200 separately around the support structure 100 And install the plurality of sheet piles 10 in a region between the plurality of supporting piles 200, respectively.

In such a configuration, since the sheet piles 10 are installed to be closed for respective portions corresponding to the areas between the supporting piles 200, the entire sheet piles 10 can be closed even in underwater work. Bar, it is easy to work, but there is an effect that it is possible to form a complete water barrier structure.

The support structure 100 is a structure for reinforcing the plurality of sheet piles 10 to be coupled to each other to be maintained in a predetermined shape, even if the conventional structure is applied, but it is more preferable to take the following configuration.

That is, as shown in Figs. 11 to 13, multiple files 20; A reference member 110 detachably coupled to the plurality of piles 20 and coupled to the inside of the plurality of sheet piles 10; A movable member 120 which is guided by the plurality of piles 20 and installed to move upward and downward from the lower side of the reference member 110, and is installed in surface contact with the inner surfaces of the plurality of sheet piles 10; The connecting member 130 is detachably connected between the reference member 110 and the movable member 120 so as to maintain a vertical gap between the reference member 110 and the movable member 120. .

In this case, the distance between the reference member 110 and the movable member 120 can be adjusted by adjusting the length of the connection member 130, rather than being integrated as in the prior art. By applying the member 130, the distance between the reference member 110 and the movable member 120 can be increased, and the shallow structure can take the opposite structure bar, while safely reinforcing the inside of the sheet pile assembly , To enable a change in the overall height of the support structure 100.

Therefore, there is an advantage that all can be applied even in the case of installing the temporary gutters at various construction positions with different depths.

In addition, since the pile 20, the reference member 110, and the movable member 120 take a separable structure that can be separated from each other, only the movable member 120 can be separated and installed on the head of the sheet pile assembly during the filling operation. As in the prior art, there is an effect of enabling a safe filling operation without a separate filling ring.

Since the reference member 110 serves to support the plurality of sheet piles 10 at a predetermined position in combination with the pile 20, it is required to combine the pile 20 with the pile 20 at a predetermined position, as will be described later. Ultimately, during the construction of the temporary curtain bar, it is necessary to separate the operation with the bar 20, in order to facilitate the separation operation, the guide hole 114a is inserted into the reference member 110 as described above is installed in the reference member 110 It is preferable that the pile 20 be guided in the vertical direction.

When the support structure 100 is required to have a high height, the overall height can be increased by increasing the number of the movable members 120.

That is, in this case, as shown in Figures 11 to 13, the movable member 120 is provided with a plurality in the vertical direction, the upper movable member 120a and the lower movable member 120b of the plurality of movable members 120. The secondary connection member 131 for detachably connecting between the upper movable member 120a and the lower movable member 120b to maintain the vertical gap of the upper and lower movable members;

Here, the case of two movable members 120 (three in total) is taken as an example, but three or more may be installed in some cases.

The connection member 130 varies the distance between the reference member 110 and the movable member 120 depending on what length is mounted, which changes the overall height of the support structure 100.

In addition, when the support structure 100 is installed in the sea, there may be some height change as the bottom surface of the movable member 120 contacts the sea floor, so that the stable support of the support structure 100 is possible in spite of this. In order to, the connecting member 130 preferably takes the chain structure.

Hereinafter, a description will be given of a preferred embodiment of the temporary structure and the construction method while explaining the construction method of the temporary film using the support structure for the temporary film according to the embodiment.
