Hereinafter, a temporary bridge construction method using piles and geo-backs according to an example of the present invention will be described in detail with reference to FIG. 3.

The temporary bridge construction method using piles and geo-bags according to an example of the present invention is a first after forming a pair of left and right holes on the ground while looking at a planned direction (longitudinal direction) from a river, lake, beach, or valley. The first step of inserting and installing the thermal pile 22; A second step of bonding a wire rope 40 to each of the first row piles 22, and stacking the geosynthetic tubes or heaves 10 filled with sand, soil or gravel to the first row pile 22; A third step of inserting and installing a second row pile 24 after forming a pair of left and right second drilling holes in the front ground of the first row pile 22; A wire rope 40 and a protection net 50 connecting the first row pile 22 and the second row pile 24 are installed on the left and right sides, and sand between the left and right protection nets 50, Fourth step of laminating the geosynthetic tube or hemp 10 filled with soil or gravel: a fifth step of repeating the four steps to a planned range; You can proceed in order.

Step 1 is a step of inserting and installing the first row pile 22 after forming a pair of left and right first drilling holes on the ground while looking at the planned direction (longitudinal direction) from the riverside, lakeside, seaside or valley. The longitudinal direction is the direction in which the temporary bridge is constructed, for example, the direction crossing a river or lake. The first column pile 22, that is, a pair of left and right piles 10 are constructed on both sides of the temporary bridge. Installation of the pile 10 can be installed by driving or inserting after boring with an auger.

The distance between the first column piles 22 is set in consideration of the width of the temporary bridge. Both sides of the temporary bridge of this embodiment may be formed as a vertical surface formed by the pile (10). That is, the geosynthetic tube or the mat 10 may be laminated and installed on both sides in a vertical direction. This is possible by the pile 10 and the wire rope 40, etc. supporting the geosynthetic tube or hemp 10 from both sides. As in the prior art, there is no need to form a trapezoid with a wide lower side, so material can be saved.

This is the step. That is, it may be easier to combine the wire rope 40 before laminating the geosynthetic tube or the hemp 10. From the point of time of the temporary bridge, the depth of water is shallow and the flow velocity is not severe to the first column pile 22, so that the wire rope 40 or the protection net 50 may not be particularly necessary.

The third step is a step of inserting and installing the second row pile 24 after forming a pair of left and right second drilling holes in the front ground of the first row pile 22. The installation of the second row pile 24 may be performed on the top of the geosynthetic tube stacked up to the first row pile 22 or the mats 10.

In step 4, a wire rope 40 and a protection net 50 connecting the first row pile 22 and the second row pile 24 are installed on the left and right sides, and the left and right side protection nets 50 This is a step of laminating geosynthetic tubes or hemps 10 filled with sand, soil or gravel therebetween. That is, the wire rope 40 coupled to each of the first row piles 22 in the second step is coupled to the second row pile 24, and at the same time, the first row pile 22 and the second row pile 24 The protection net 50 is coupled between them. By doing this, a space is formed between the left and right piles 10 by the protection net 50 and the wire rope 40, and geotextile tubes or stumps 10 are stacked in the space.

That is, by connecting the first row pile 22 and the second row pile 24 with a wire rope 40, installing a protective net 50 at the same time, and then laminating the geosynthetic tube or stalk 10, Tubes or mats 10 are constrained in the transverse direction by the wire rope 40 and the protection net 50, so that the structural stability of the temporary bridge can be increased.

Step 5 is a step of repeating step 4 to a planned range. The planned range usually refers to the range that crosses a river or lake. After that, similar to the second step, geotextile tubes or sacks 10 are stacked to finish.

Further comprising the step of installing water pipes 30 to enable water passage across the transverse direction under the stacked geosynthetic tubes or mats 10, and filling gravel around the water passages 30 can do.

It may further include the step of laminating the geosynthetic tube or sacks 10 filled with sand, soil, or gravel so as to protrude in the transverse direction to one of the left and right sides of the geosynthetic tube or the sacks 10 stacked in the longitudinal direction. have.

When the geosynthetic tube or the mat 10 is stacked so as to protrude in the transverse direction, the soil may be filled instead of the geosynthetic tube or the mat 10 at the position where the structural foundation pile 60 is installed. The soil is to easily install the foundation pile 60 for the structure as described above.

After the above step, after vertically excavating the location where the soil was filled, the step of installing the structural foundation pile 60 may be further included. Excavation can be bored with an auger or the like.

It may further include the step of installing the steel cross-linking 70 in the deep water portion and the intermediate portion of the geosynthetic tube or hemp 10 to be laminated.

By including the step of installing the steel cross-linking 70, the shallow part is constructed a temporary bridge by stacking geosynthetic tubes or hemps 10 filled with sand, soil, or gravel, and the intermediate part of the shaft part on both sides, That is, a temporary bridge can be constructed by constructing a steel bridge 70 in the deeper part.
