Abstract

The present invention relates to a soil retaining plate construction method using a base H-pile for sheathing inside a building, allowing a foundation extension construction for a building to be easily performed even in a narrow space. The soil retaining plate construction method comprises: a soil retaining H-pile embedding step of rotating a soil retaining H-pile to be directly penetrated; a partial excavation step of repeatedly performing partial excavation one or more times; a step of installing a partial soil retaining plate; and a step of performing an entire excavation. Since a soil retaining H-pile having a short length is rotated to be embedded without a work to drill the ground, the H-pile can be embedded by using a small sized-rotational means operated to embed the H-pile in a narrow space such that construction for soil retaining can be easily performed inside a building without a spare space. When a long embedded length is required, a length of the pile is extended, and then the pile can be constructed. A polishing bit is formed on a cone part formed on a perforation part of the H-pile for retaining soil to allow the pile to be embedded even when hard material exists underground.

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a soiled retaining plate construction method using H-pile for sheathing,

The present invention relates to a soil plate method using a foundation H file for building internal soil that can easily perform the basic enlargement construction of a building even in a narrow space.

The retention method corresponds to the pressure of soil on the back of the retaining wall. It is a method to support earth pressure and water pressure for the purpose of preventing ground collapse and water penetration due to foundation excavation.

In order to insert an H file (thumb pile) in such a retention method, the position where the H file is inserted is punctured by using an auger or a corresponding device, and a soil plate, a welt, and a strut are installed with the H file inserted This is the method that is preceded by the clogging of the soil and water pressure and the earthquake.

Examples of the earth retaining method using the earth plate include the CIP method, the MIP method, the PIP method, and the SCW method.

On the other hand, there are related arts such as Korean Registered Patent No. 10-1179770 and Korean Patent Laid-Open No. 10-2008-0085260, and these prior arts are mostly related to large-scale retention methods.

On the other hand, it is often necessary to expand or remodel the building in order to shorten the cost and the working time, rather than building the building after demolishing the building within the limited space.

However, since buildings constructed with old low-rise buildings often fail to form buildings high due to weakening of the ground, rather than building high height due to the view due to problems in the building law, Foundation work is essential.

However, most of the retention methods are not suitable for the retention method for foundation work in a building with a small floor area and a small area because the work is performed using large equipment.

Especially, this phenomenon appears especially in the old buildings where the sea was buried in the land where the building was built, and it is necessary to take measures against it.

In order to solve the above-mentioned problems, the present invention provides a soil plate method using a foundation H file for building residues, which can easily carry out earth retaining work even in a narrow space, There is a purpose.

In the present invention, since a short length H file for an earth retaining pile is rotated without piercing the ground, the file is inserted using a small rotating means that operates even in a narrow space for drawing the H file, The construction for earthquake can be easily carried out.

In addition, when the penetration length is long, it is possible to construct the damper by connecting it after extending the length, and it is a useful invention in which the abrasive bit is formed in the concave portion formed in the perforation of the H file for the earth retaining, .

[

Next, the perforation 20 is coupled to the lower side of the first H beam 10 to penetrate the ground H into the ground while drilling the ground.

That is, in the above-described perforation 20, a plate-like coupling plate 21 for coupling with the first H beam 10 is formed on the upper side. A hole 21a corresponding to the first horizontal coupling hole H1 of the first lower supporting plate 18 formed on the first H beam 10 of the H file 30 for the ter- And can be engaged with the bolt (B) and the nut (N).

The diameter of the first screw 23 formed on the upper side of the first and second screws 23 and 24 is larger than the diameter of the second screw 24 formed on the lower side of the first and second screws 23 and 24, It is preferable that the diameter of the first H beam 10 is larger than that of the first H beam 10.

In addition, a cone-shaped cone portion 25 made of a high-strength material is formed on the lower side surface of the shaft 22 so as to be able to perforate the ground.

Here, stones of various sizes in addition to soil can be formed on an ordinary ground.

Accordingly, a plurality of polishing bits 25a may be formed on the outer circumferential surface of the above-mentioned cone 25. [

Although the abrasive bit 25a may be formed of various materials, it is preferable that the abrasive bit 25a is made of industrial diamond to improve the efficiency.

In the meantime, the H file 30 for a ter- minerator according to the present invention is constructed so as to be able to apply the earth retaining film even in a narrow space as in a building.

Therefore, the length of the above-described H file 30 for a terahertz wave extending in the vertical direction of the first H beam 10 is inevitably short.

Accordingly, the present invention may further include means for extending the H-file 30 for the ter- minerator when a deeper depth is required.

That is, the H-file 40 for extending the length of the first H-beam 10 of the above-described ter- minal H-file 30 and the extension member 50 for connecting them may be further configured.

The length-extending H-file 40 is formed such that the second left and right side plates 41 and 42 are spaced apart from each other by a predetermined distance, and between the second left and right side plates 41 and 42, The upper and lower space portions 44 and 45 are formed on the upper and lower sides with respect to the second horizontal plate 43, The left and right side plates 41 and 42 and the second horizontal plate 43 extend in the vertical direction to form an H beam.

At least one second vertical coupling hole V2 is formed on the upper and lower ends of the second left and right side plates 41 and 42 and one or more second vertical coupling holes V2 are formed on the second upper and lower support plates 47 and 48. [ Two horizontal coupling holes H2 are formed.

Meanwhile, the H file 30 and the H-length file 40 having the above-described structure can be firmly connected to each other by the extension member 50.

The extension member 50 is connected to the first and second vertical coupling holes V1 and V2 formed in the terference H file 30 and the length extension H file 40 and the third and fourth vertical coupling holes The right and left side plates 51 and 52 are spaced apart from each other by a predetermined distance and the left and right side plates 51 and 52 of the extension members Right side plates 51 and 52 while abutting against the second lower support plate 48 formed on the first upper support plate 17 formed on the first housing 30 and the H- And an extension member horizontal plate 53 for connecting the extension member 53 to each other.

Particularly, in the extension member horizontal plate 53, a first upper support plate 17 formed on the tappet H file 30 and a first upper support plate 17 formed on the second lower support plate 48 of the H- And a third horizontal coupling hole H3 corresponding to the two horizontal coupling holes H1 and H2 are formed.

In order to insert the H-file 30 for the terrestrial apparatus into the ground, the present invention may also be applied to a first upper support plate 17 formed at the upper end of the first H beam 10 or a H- The second upper support plate 47 may be detachably attached to the second upper support plate 47.

2. Retaining method

end. Step for inserting H file for earthwork

This step is a step for forming the foundation for installing the soil plate 1. [

Therefore, after the soil file H 100 is placed at a location outside the space to be terraced, and the soil file H 100 is placed in the space, the soil file H file And rotates the H-file 30 for the ter- minal of the optical disk 100.

The cone portion 25 formed in the perforation 20 of the ter- rider H file 30 which has been in contact with the ground surface has a function of adjusting the weight of the soil file H 100 and the rotating means R The force acts in the direction of gravity to insert the cone portion 25 while piercing the ground surface.

The first and second screws 23 and 24 are formed on the outer circumferential surface of the shaft 22 in the perforation 20 so that the perforation 20 can be further extended by expanding the space after the cone 25 is perforated, So that insertion of the first H beam 10 coupled to the upper end of the first H beam 10 can be smoothly performed.

Meanwhile, the first H beam 10 inserted into the space punctured by the perforation 20 of the H-file 30 for the terahertz, as described above, even if the insertion is made through the perforated portion, It falls down.

In this process, the first H beam 10 of the present invention is provided with a first support plate 16, and the first left and right side plates 11 and 12 of the first H beam 10 Therefore, even if a conventional H file is rotated, the first H beam 10 of the ter- minal H file 30 can be prevented from being damaged, and it can be fitted under the ground.

On the other hand, solid soil obstacles such as stones may exist in the soil below the ground.

In the present invention, since a plurality of polishing bits 25a are formed on the outer circumferential surface of the cone portion 25 of the perforation 20, even if there are such obstacles, the H file 30 for the ter- .

Particularly, in the present invention, the first and the lower support plates 17 and 18 are welded to the upper and lower sides of the H file 30 for the tappet, so that the first H plate 30, together with the first support plate 16, (10) is prevented from being twisted.

In addition, since the earth retaining method of the present invention can be used in a building with low height, etc., the length of the H-file 30 for a ter- minator extending in the vertical direction is usually about 1 to 1.5 m.

Therefore, when the terra cotta is performed to a deeper position, the H file 100 for soil retention must be formed to a deeper position.

In the present invention, this problem can be solved through the H-file 40 for extending the length.

4, the rotary unit coupling unit 60 for coupling with the rotary unit R is connected to the first upper support plate 17 formed on the first H beam 10 of the H-file 30 for the terahertz When the work is performed after the extension member 50 and the H-file 40 for extending the length are fastened by using the bolts B and N at the position and the work is performed, So that it is possible to perform the operation of inserting the soil file H 100 while adjusting it.

Particularly, in the present invention, it is possible to finish by repeatedly carrying out the work of inserting the above-mentioned H file 100 for earth retaining.

I. Partial turndown step

This step is a step of partially delimiting the periphery of the H-file 100 for the earth retaining structure that has been inserted into the ground through the above-described step of inserting the H-file for the earth retaining structure, and more specifically, A step of inserting the soil plate 1 between the first and the lower space portions 15 and 16 of the earth retaining H file 100 and the other earth retaining H file 100 facing the earth retaining H file 100 is performed.

Therefore, in this step, the tearing operation must be performed in consideration of the depth and area enough to insert the soil plate (1).

Particularly, the soil plate 1 described above is installed in the first upper support plate 17 and the first support plate 17 of the first H beam 10 formed in the H-file 30 for the terra cotta H file 100, The first upper and lower space portions 14 and 15 and the first upper and lower space portions 14 and 15 between the first support plates 16 formed between the first and second support plates 16 and 16, ) And the first lower support plate (18).

Therefore, the depth of the partial tearing may be performed in consideration of the vertical distance between the respective support plates 16, 17, 18.

Such partial trimming operation must be performed at a neighboring location where the H-file 100 for soil retention is inserted.

All. Partial soil board installation step

This step is a step of inserting the soil plate 1 into the space that has been touched in the above-mentioned partial trenching step.

In carrying out this step, the thickness of the soil plate 1 may be made thinner than the distance between the first left and right side plates 11 and 12 of the first H beam 10, The height of the weir plate 1 should be made longer than the distance between the H files 30 for the ter- minal H beams 100 for use by the respective support plates 16, It is preferable to form them so as to fit the spaced distances between them.

This partial soil layer installation step is intended to prevent the soil from collapsing on the side of the space where the tuff is made before the tuff is completely carried out.

Therefore, in the present invention, the above-described partial clumping step and partial clay sheet mounting step are repeatedly performed to form the first support plate 16 formed at the lowermost portion of the first H beam 10 of the H- And the first lower supporting plate 18 are formed, the turntable and the turntable 1 should be installed.

Since the soil plate 1 is formed between the support plates 16, 17 and 18 in the vertical direction, the thickness of the support plates 16, 17 and 18 may be set to be vertically spaced apart from each other. There is nothing.

Therefore, in the present invention, it is possible to prevent the soil pile H file 100 protruding downward by the thickness of each of the support plates 16, 17, 18 on the lower surface of the soil plate 1, So that the whole vertical direction of the H-beam 100 for the earth retaining film can be installed in the soil plate 1 without any gap.

la. The entire erase step

In this step, all the soil plates 1 are installed in the space to be tapped, and then the whole space is dismantled, and a detailed description thereof will be omitted.

On the other hand, in the present invention, after the above-described partial dismantling step is carried out for the first time, a wristband mounting step in which a wrist band (not shown in the drawing) is provided and a strut braid mounting step in which a wristband (not shown in the drawing) is provided can be performed.

In addition, the length H of the ter- minal H file 30 constituting the securing H file 100 according to the present invention is not long, and when the ter- minerator is to be performed in a range exceeding the length, It is possible to carry out the step of installing the above-mentioned partial tear-off device and partial tear-off plate from the length-extending H-file 40 after connecting the length-extending H-

As described above, according to the present invention, it is possible to directly penetrate the H file 100 for the earth retaining structure, but to extend the length of the H file 100, so that the earth retaining work for the terra cotta can be performed in a narrow space.
