Description

[0001] The present invention relates to a file guide structure for ground excavation and a file installation method using the same,

The present invention relates to a file guide structure for ground excavation and a file installation method using the same. More particularly, the present invention relates to a file guide structure for ground excavation that guides a file on both sides thereof, And a file installation method using the same.

In various construction and civil engineering works, a treadmill is first performed in order to provide a space for a structure. In such a treadmill, a continuous wall is installed so that the surrounding ground does not fall into the installation space of the structure, .

In addition to the function of enduring the earth pressure of the surrounding ground as described above, the continuous wall also performs an order function to prevent water flowing in the surrounding ground from flowing into the installation space of the structure.

The continuous wall is generally composed of a continuous pile of piles formed by filling holes of a certain size in the ground and then filling concrete or mortar. Such continuous walls are currently applied to various types of construction methods It is being built.

In the conventional continuous wall construction method, the piles are brought into contact with each other by a predetermined area so that no gap is formed between the piles connected to each other. However, since the piles are formed independently of each other and the ends are joined to each other, There is a problem that a gap is generated between the files if the files are not formed exactly perpendicularly on the ground.

If a gap is formed in the continuous wall, the function of the continuous wall is significantly deteriorated. Therefore, development of a method for inserting the casing perpendicularly to the ground is required so that a gap is not generated in the continuous wall.

As a technique for guiding a file to be inserted vertically into the ground as described above, there is a technique in which a structure in which a guide hole for guiding a file is directly formed in an on-site worker by a worker is molded into a mold, and then concrete is poured into the mold structure And then cured to induce vertical insertion of the file.

However, this method has a problem in that the worker has to construct the structure for each ground where the file is installed, and the work can not be performed until the concrete filled in the structure is cured, resulting in poor workability.

Above all, once the construction of the file is completed, the structure for guiding the file must also be removed together. At this time, the structure once used can not be reused, resulting in a waste of resources.

Also, the diameter of the file can be changed according to the construction environment. In this case, the guide structure needs to be made again to match the diameter of the file.

In addition, conventionally, there is a problem that it is necessary to separately manufacture a mold when the cap concrete is fixed to fix the upper end of the files for structural stability.

Korean Patent No. 10-0864110

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a guide structure in which the guide structure can be variably operated even when the diameter of a file is different, And a file installation method using the same.

A file guide structure for ground excavation according to an embodiment of the present invention includes a main body module including a unit unit and a pair of units arranged to face each other; And a guide unit which is composed of a unit unit and which is fastened to the opposite surfaces of the pair of main body modules so as to face each other so as to guide insertion of the files.

At this time, the guide unit is configured such that a concave arcuate groove whose sides are symmetrical on both sides is formed, and an arc shape is formed together with a neighboring guide unit.

In addition, the guide unit is adjustable in mutual spacing with neighboring guide units when the guide unit is coupled to the main body module.

In addition, two or more fasteners are formed on the upper surface of the main body module in parallel, and spacing grooves are formed to maintain a gap between the pair of main body modules facing each other, wherein a plurality of fastening grooves And the fasteners of the pair of main body modules are fitted into the fastening grooves.

Meanwhile, in the file installation method using the file guide structure for ground excavation, a pair of mutually facing main body modules are arranged side by side along a construction area of the file, and then the space holding tool according to any one of claims 1 to 4 Installing a main body module; A guide unit coupling step of coupling the guide units according to any one of claims 1 to 4 to the opposite surfaces of the main body module, respectively, so as to correspond to the diameters of the piles to be installed; A file inserting step of inserting a file into the ground by being guided by the guide unit; And a cover step of covering the soil so as to expose only a part of the file after removing the main body module.

A forming step of forming a space for placing the cap concrete by disposing a pair of main body modules, from which the guide unit has been removed, on both sides along the exposed piles after the embedding step; A cap concrete pouring step for pouring concrete into the space; And removing the main body module after the cap concrete is cured.

For example, a partition wall groove having a predetermined depth may be formed on a facing surface of the main body module, the pair of main body modules being arranged to face each other in the die forming step, And a partition is inserted and fixed in each of the partition wall grooves.

As described above, according to the file guide structure for ground excavation according to the present invention and the file installation method using the same, the pre-fabricated guide structure can be variably operated even when the diameter of the file is different, Since the installation space of the cap concrete can be formed by using the body module, there is an advantage that the workability is excellent because no separate formwork construction is required.
