Description

TECHNICAL FIELD [0001] The present invention relates to a method for manufacturing a wall of a CIP process using a scratch structure,

The present invention relates to a method of making a wall for construction of a retaining wall to be constructed in a construction and civil engineering field, and more particularly, to a method of manufacturing a wall structure for a retaining wall, The present invention relates to a method of manufacturing a water wall of a CIP method using a scratch structure that can be realized.

As is well known, it is common to construct a retaining wall or the like when it is desired to perform a subterranean digging work or the like in various construction and civil engineering sites. Here, it is common to use a retaining wall retaining method, for example, as a retaining wall construction.

Particularly, as a watertight retention method, for example, it is possible to carry out close construction with an existing turf structure, to minimize the width of the turf structure, and to prevent the cast in place (CIP) pile method is mainly used.

1 is a plan view of a water wall structure constructed according to a conventional method.

Referring to FIG. 1, each of the files 110-1 to 110-5 constituting the water barrier wall includes a casing (for example, a cylindrical casing) for holding a perforation hole while perforating the ground using a perforating machine such as an auger machine, The H beam 112 (or reinforcing bar) is inserted into the casing, the inside of the casing is filled with a mortar 114 and the like, and then the casing is pulled out through the drawing device .

On the other hand, there is a problem that a water hole formed by a conventional method is not precisely connected between adjacent columns due to its manufacturing characteristics, and a minute gap (for example, a gap of several millimeters to several centimeters) is generated. (For example, deterioration of the water-drawing performance in which water and soil are introduced through the gap).

Therefore, conventionally, auxiliary files 120-1 to 120-4 are formed between adjacent files by performing an auxiliary method such as grouting.

That is, the auxiliary file 120-1 reinforces a gap that can occur between the files 110-1 and 110-2, and the auxiliary file 120-2 supports the file 110-2 and the file 110-2. The auxiliary files 120-3 reinforce the crevices that can be generated between the files 110-3 and 110-4 and the auxiliary files 120-3, 4 is for reinforcing a gap that can be generated between the file 110-4 and the file 110-5. The conventional water wall is formed by using auxiliary files produced through separate construction, Thereby preventing water or soil from flowing through the gap.

However, in the conventional method of producing a water wall, there is a problem that a construction period is unnecessarily extended because a grouting process for forming auxiliary files between files must be performed several times, It is a factor that causes it.

It is to be understood that the following terms are defined in consideration of the functions of the present invention, and may be changed according to intentions or customs of a user, an operator, and the like. Therefore, the definition should be based on the technical idea described throughout this specification.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Example 1]

FIG. 2 is a plan view of a water wall structure of a CIP method using a scratch structure according to an embodiment of the present invention. FIG. 3 is a cross- Fig.

Referring to FIG. 2, in the files 210-1 to 210-5 manufactured according to the present embodiment, the entire interior of which the skeletal member 212 is inserted is filled with a filling material 214 such as mortar Structure. Here, the skeletal member 212 may mean, for example, an H beam, a reinforcing bar, etc., and each file may be defined, for example, as a column.

At this time, each file constituting the water barrier can be produced as a file filled with mortar only without inserting a skeletal member into the file according to the installation environment of the water wall, the use purpose, or the like.

The order reinforcement areas 216-1 to 216-4 are formed between the files 210-1 to 210-5 adjacent to each other. The order reinforcement areas 216-1 to 216-4 It can be in the form that the soil and the fillers of each file are mixed with each other.

3, the order reinforcement areas 216-1 to 216-4 formed in the vertical direction (length direction of the files) between the files are a mixture of the gravel and the mortar, (For example, a clearance of several millimeters to several tens of millimeters, which may degrade the order performance). In this case, the desired order performance and support performance can be obtained. For this purpose, A scratch structure as described above can be used.

4 is an exemplary perspective view illustrating a principle of inserting a scratch structure into a casing for manufacturing a water wall according to an embodiment of the present invention.

Referring to FIG. 4, a casing 410 for holding a perforation hole, which functions as a form when a cylindrical casing 410 is used for manufacturing a water wall, that is, a water wall, is used. For example, an auger machine, or the like, so as to be inserted into the target position of the ground.

In this embodiment, in order to form an order reinforcement region (that is, a region where soil and mortar are mixed through scratches) between adjacent files, a perforation hole retaining member A scratch structure 420 is inserted into the casing 410. The scratch structure 420 is provided at its lower end side with a cylindrical shape corresponding to the shape of the casing 410 The structure body 422 and the upward end 424a may be fixed to one side of the lower end of the structure body 422 and the other end 424b may be a scratch member 424 of a free end made of elastic material.

Here, the free end of the scratch member 424 may have a shape that is gently curved inward at the end thereof. This is because the skeletal member and the filler are inserted and filled in the casing, respectively, So that insertion of the scratch structure 420 is smoothly performed when the insertion is repeatedly carried out for a short period of time.

At this time, the scratch member 424 constituting the scratch structure 420 may be any one of, for example, a rake shape, a toothed wheel shape, and a screw shape, and may also include a filler material Can be applied to any shape as long as it is capable of scratching to sufficiently mix each other.

A plurality of through holes 422a are formed in the structure main body 422 at regular intervals on the front surface of the main body 422. When the filler such as mortar is filled in the scratch structure 420, In order to allow a part of the liquid to flow out of the through hole 422a and fill the space between the casing 410 and the scratch structure 420.

That is, each of the through holes 422a may provide a function of discharging the filler filling the inside of the scratch structure 420 into the space between the casing 410 and the scratch structure 420. Here, the size (diameter) of each through-hole 422a is set to a size such that the filling material filled in the scratch structure 420 can be naturally discharged into the space between the casing 410 and the scratch structure 420 .

Next, a series of processes for manufacturing a water wall according to the present embodiment will be described using a scratch structure having the above-described shape.

First, a perforation hole holding casing 410 is inserted at a target position of the ground by performing a perforating process (e.g., rotary perforation, percussion perforation, etc.) using a perforating machine such as an auger machine.

A cylindrical structure main body 422 corresponding to the shape of the casing 410 and an upwardly facing end 424a are provided in the casing 410 so as to have an expandability (or expansion elasticity) The scratch structure 420 is fixed to one side of the lower end side of the structure main body 422 and the other end 424b is made of a scratch member 424 having an elastic free end.

Here, the outward expandability (or expansion elasticity) of the free end of the scratch member 424 is such that the free end of the scratch member 424, when pulling out the casing through the drawing process, It can be said that the elasticity can be applied to the degree reinforcing region formed in the longitudinal direction of the adjacent pile by an appropriate degree of rigidity.

A skeletal member such as a H beam, a reinforcing bar, or the like is inserted into the scratch structure 420, and a scrubbing structure such as a mortar or the like is carried out, so that the scratch structure 420, into which the skeleton member is inserted, Lt; / RTI >

Thereafter, when the skeletal member is inserted and the mortar is filled, the pulling process is performed to pull out the casing 410. When the casing 410 is pulled out, the free end of the scratch structure 420 is extended in the outward direction For example, in the range of several millimeters to several tens of millimeters, wherein the free end of the scratch member 424 is spaced from the adjacent file (e.g., a curing of concrete period of time) The adjacent reinforcing region formed in the longitudinal direction of the cured left or right adjacent file).

Of course, when the file is inserted and generated at the target position of the ground for the first time, since there is no adjacent file, even if the casing 410 is pulled out, the free end of the scratch member 424 is only expanded to a certain size It will not come into contact with the degree-reinforcing region of.

Then, when the scratch structure 420 is pulled out in such a manner that the scratch structure 420 is repeatedly shortened and drawn and inserted repeatedly, the free end 424b of the scratch member 424 causes the surrounding gravel And the surrounding soil and the filler (mortar) are mixed by scratching the outer soil of the casing before the drawing. Thus, the region where the soil and the filler are mixed functions as an order reinforcement region for improving the order function. At this time, the scratch member 424 may be, for example, a rake shape, a toothed wheel shape, or a screw shape.

That is, according to the present embodiment, a file in which a degree-reinforcing region is formed in the longitudinal direction of the file is formed at a target position of the ground through processes such as insertion of a casing, insertion of a skeletal member, filling of a filler, drawing of a casing, and drawing of a scratch structure By sequentially repeating these processes by the N-th order, it is possible to manufacture a water wall made up of a plurality of files connected in a form in which the order reinforcing regions are in contact with each other.

For example, as shown in FIGS. 2 and 3, assuming that the order wall is composed of five files, the adjacent files are arranged in the order from left to right (210-1 to 210-5) (Generated in the order of 210-5 to 210-1) from the right side to the left side, and between the files adjacent to each other, by the scratch performed while drawing out the scratch structure, 216-1 to 216-4 will be formed.

In the meantime, in the method of producing a water wall of the present embodiment, a file is formed by inserting a skeleton member (for example, H beam, reinforcing bar, etc.) into each of the files constituting the water barrier wall. However, It is needless to say that it is also possible to produce a file in which only mortar is filled without inserting a skeletal member into the file according to the installation environment or use of the water wall.

[Example 2]

FIG. 5 is a plan view of a water wall structure of a CIP method using a scratch structure according to another embodiment of the present invention. FIG. 6 is a cross- Fig.

Referring to FIG. 5, in the files 510-1 to 510-5 produced according to the present embodiment, the whole interior of which the skeletal member 512 is inserted is filled with a filler 514 such as mortar Structure. Here, the skeleton member 512 may mean, for example, an H beam, a reinforcing bar, or the like, and each file may be defined, for example, as a column.

The order reinforcement areas 510-21, 510-22, 510-41, and 510-42 are formed between adjacent files 510-1 to 510-5. The order reinforcement areas 510 -21, 510-22, 510-41, 510-42) may be a form in which the fillers of the soil and each file are mixed with each other.

6, the order reinforcement areas 510-21, 510-22, 510-41, and 510-42 formed in the vertical direction (the length direction of the files) between the files are mixed with the soil and mortar (For example, a clearance of several millimeters to several tens of millimeters, which may degrade order performance) is generated between the files, thereby achieving a desired order performance and support performance. For this purpose, a scratch structure as shown in the central part of FIG. 7 may be used as an example.

At this time, the three files 510-1, 510-3, and 510-5 located apart from each other by a predetermined interval (spaced apart from each other by a method of skipping one file) And the remaining two files, that is, the file 510-2 located between the files 510-1 and 510-3, the file 510-2 located between the files 510-3 and 510-5, The file 510-4 located in the file 510-1 may be a file formed by using a scratch structure having a shape as shown in Fig. 7 as an example.

For example, the order reinforcement area 510-21 and the order reinforcement area 510-22 are formed by scratching the scratch structure at the time of forming the file 510-2 so that the surrounding soil and the filler (the inside of the file 510-2) Can be simultaneously formed so as to be in close contact with the longitudinal wall face of the right side face of the pile 510-1 and the longitudinal wall face of the left side face of the pile 510-3 by being mixed with each other, (510-4) and the order reinforcement regions 510-42 are formed by the surrounding soil and the filler (the filler inserted into the file 510-4) through the scratch of the scratch structure when the file 510-4 is formed, So as to be brought into close contact with the longitudinal wall face of the right side face of the file 510-3 and the longitudinal wall face of the left side face of the file 510-5, respectively.

That is, the respective files of the water wall produced according to the present embodiment may be, for example, odd-numbered files formed in a normal manner not using a scratch structure, and even-numbered files may be files formed using a scratch structure .

Therefore, in the case of the water wall according to the present embodiment, since the number of times of using the scratch structure is reduced to about 1/2 as compared with the water level wall of the above-described first embodiment, the construction period of the water wall can be shortened relatively short , Which can be expected to have a side effect of further reducing the production cost of the water wall.

FIG. 7 is an exemplary perspective view for explaining a principle of forming a file having an order reinforcement region between two files spaced apart to produce a water wall according to another embodiment of the present invention. FIG.

7, a casing 710 for holding a perforation hole is used, which serves as a mold when a cylindrical casing 710, for example, is used for manufacturing a water wall, (E.g., 510-1, 510-3) spaced apart by a predetermined distance by performing a perforating process using a perforating machine such as an auger machine.

In this embodiment, in order to form an order reinforcement region (that is, a region where soil and mortar are mixed through scratches) on both sides of a file to be positioned between the two files 510-1 and 510-3, The scratch structure 720 is inserted into the casing 710 for holding the perforation holes inserted into the ground through the through hole 720. The scratch structure 720 is provided at its lower end side, A cylindrical structural body 722 corresponding to the shape of the structure body 710 and an upwardly facing end 724a are fixed to one side of the lower end side of the structure body 722 and a downwardly opposite end 724b is fixed to a scratch member 724).

Here, the free end of the scratch member 724 may have a gently curved shape at its end inward. This is because, after inserting and filling the skeletal member and the filler into the interior of the casing, So that insertion of the scratch structure 720 is smoothly performed when the insertion is repeatedly performed in a short time.

The scratch member 724 constituting the scratch structure 720 may be any one of a rake shape, a toothed wheel shape, and a screw shape as in the case of the tent room example 1, And any shape can be applied as long as it can scratch the filling material (mortar) so that the filling material (mortar) can be sufficiently mixed with each other.

A plurality of through holes 722a are formed in the structure main body 722 at predetermined intervals on the front surface of the main body 722. These through holes 722a are formed in the inside of the scratch structure 720 when the filling material such as mortar is filled. In order to allow a part of the air to flow out of the through hole 722a to fill the space between the casing 710 and the scratch structure 720.

That is, each of the through holes 722a may provide a function of discharging the filling material filling the inside of the scratch structure 720 into the space between the casing 710 and the scratch structure 720. Here, the size (diameter) of each through hole 722a is set such that the filling material filling the inside of the scratch structure 720 can be discharged to the space between the casing 710 and the scratch structure 720 naturally .

First, two files (for example, 510-1 and 510-3) positioned apart from each other by a predetermined interval (spaced apart by one file interval) through a normal construction method that does not use a scratch structure for the purpose of improving convenience and understanding of explanation ) Are formed on the surface of the substrate.

Here, the normal construction method may mean a construction method in which a file is formed at a target position of the ground through processes such as casing insertion, skeletal member insertion, filler filling, and casing drawing.

When the two files 510-1 and 510-3 are spaced apart from each other by a predetermined interval as described above, the perforating process (e.g., rotary perforation, percussion perforation, etc.) using a perforating machine such as an auger machine is performed, A casing 710 for holding a perforation hole is inserted at a position between the file 510-1 and the file 510-3.

A cylindrical structure body 722 corresponding to the shape of the casing 710 and an upwardly facing end 724a having an expandable (or expanding elasticity) in the outward direction inside the casing 710, And a scratch structure 720 which is fixed to one side of the lower end side of the structure body 722 and whose downwardly opposite end 724b is made of a scratch member 724 which is a free end of an elastic material.

A skeletal member such as a H beam, a reinforcing bar, or the like is inserted into the scratch structure 720, and a filling material such as a mortar or the like is subjected to a process of inserting a filling material into the inside of the scratch structure 720 into which the skeletal member is inserted. Fill.

When the skeletal member is inserted and the mortar is filled, the pulling process is performed to pull out the casing 710. When the casing 710 is pulled out, the free end of the scratch structure 720 is expanded to the outward direction For example, in the range of several millimeters to several tens of millimeters, whereby the free end of the scratch member 724 is separated from the adjacent two files (for example, And the two right-side files 510-1 and 510-3) with appropriate rigidity.

Then, when the scratch structure 720 is pulled out in such a manner that the scratch structure 720 is repeatedly pulled out, that is, drawn and inserted repeatedly, the free edge 724b of the scratch member 724 causes the surrounding gypsum And the filler material is mixed with the filler material (mortar) around the left and right sides by scratching the outer filler material between the two files and the filler material. Thus, . At this time, the scratch member 724 may be, for example, one of a rake shape, a toothed wheel shape, and a screw shape.

That is, according to the present embodiment, a file in which the degree-reinforcing area is formed on both sides in the longitudinal direction of the file through processes such as insertion of a casing, insertion of a skeletal member, filling of a filler, drawing of a casing, drawing of a scratch structure, And the process is successively repeated (progressed) so that the degree reinforcing regions on both sides are simultaneously connected to each other in such a manner that they closely contact longitudinal wall surfaces of two adjacent files. Can be manufactured.

5 and 6, it is assumed that the file is composed of five files, the file 510-1 and the file 510-3 may be stored in a normal manner without using a scratch structure The file 510-2 is formed by the manufacturing method of this embodiment using the scratch structure after the first structure is formed by the construction method, that is, the order reinforcement area 510-21 is brought into close contact with one wall surface of the file 510-1 A file 510-2 having a shape in which the order reinforcement area 510-22 closely contacts one wall surface of the file 510-3 is formed.

By proceeding in the same manner as the construction method of forming the file 510-2, the order reinforcement area 510-41 is brought into close contact with one wall surface of the file 510-3, and the order reinforcement areas 510-42 Forms a file 510-4 having a shape that closely contacts one wall surface of the file 510-5.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims. It is easy to see that this is possible. That is, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the present invention.
