Description

TECHNICAL FIELD [0001] The present invention relates to a reinforcement member for reinforcing earth retaining walls,

Field of the Invention [0002] The present invention relates to a civil engineering field, and more particularly, to a reinforcing member of a reinforced earth retaining wall.

A reinforced earth retaining wall refers to a wall structure in which a reinforcing member is provided toward the rear of a block stacked on a surface thereof and a reinforcing member is buried in the rear soil soils compactioned behind the blocks to resist the earth pressure.

1 and 2 show a conventional reinforced earth retaining wall.

The reinforcing member 20 is inserted into the longitudinal insertion groove 11 and the transverse insertion groove 12 of the block 10 whose front end is formed to have a surface structure and the rear end is embedded in the rear soil.

The reinforcing member 20 of the lattice structure is formed by combining a plurality of the longitudinal members 110 and the lateral members 120 in a lattice-like structure.

However, since the conventional reinforcement member 20 is formed so that one reinforcing bar is coupled to each other to form the longitudinal member 110 and the transverse member 120, no reinforcing structure is formed at the stress concentration portion , There is a problem that the strength is weak and the use of materials is not efficient.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a reinforcing member for reinforcing earth retaining walls which is excellent in strength and can be used efficiently.

In order to solve the above problem, the present invention is characterized in that a front end is inserted into a longitudinal insertion groove (11) and a transverse insertion groove (12) of a block (10) A longitudinal member (110) and a transverse member (120) are joined together by welding in a state where they are in mutual contact with each other, and a plurality of longitudinal members The reinforcing member 100 of the reinforced earth retaining wall according to the present invention is characterized in that the connecting portion 130 is formed in a rectangular shape having a longer transverse length than the longitudinal direction.

The longitudinal member 110 and the transverse member 120 are formed in a circular cross-sectional structure, and the rectangular coupling unit 130 includes a plurality of the longitudinal members 110 in one transverse member 120 Is preferably formed by bonding.

The longitudinal member 110 is formed in a circular cross-sectional structure, and the transverse member 120 is formed in a rectangular cross-sectional structure having a width larger than the height, It is preferable that the one longitudinal member 110 is formed by joining one longitudinal member 120 to the other longitudinal member 110.

It is preferable that the transverse member 120 is formed by a member having a circular cross-section structure.

The rectangular coupling part 130 is formed at a front end of the transverse member 120 and an extension part 121 protruding forward from the rectangular coupling part 130 is formed at the front end of the transverse member 120 .

The rectangular coupling part 130 may be formed at a plurality of points along the longitudinal direction of the transverse member 120.

The rectangular coupling portion 130 is preferably quenched by a low-temperature gas so as to prevent oxidation after welding.

Is provided in the longitudinal insertion groove (11) and the transverse insertion groove (12) of the block (10) so that the longitudinal members Is preferably protruded toward the front.

The longitudinal member 110 is preferably formed in a curved structure.

The block 14 is formed in front of the supporting portion 13 of the block 10 forming the longitudinal insertion groove 11 and the lateral insertion groove 12 before the block building step, (10) in order to obtain the desired properties.

5 is a side view of the second embodiment;
6 is a plan view of the third embodiment.
7 is a plan view of the fourth embodiment.

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

3, the present invention is basically characterized in that a front end is inserted into a longitudinal insertion groove 11 and a lateral insertion groove 12 of a block 10 which is formed to have a surface structure, And a plurality of longitudinal members and transverse members joined together in a lattice-like structure.

Here, the longitudinal member 110 and the transverse member 120 are welded to each other to form an engaging portion 130. The engaging portion 130 has a transverse direction length Is formed in a long rectangular structure.

That is, in the reinforcing member 100 having the lattice structure, stress concentration occurs at the joining portions of the longitudinal member 110 and the transverse member 120. In this joining portion, rather than a conventional square coupling portion, The enlarged rectangular coupling portion 130 is formed to increase the strength of the joint between the longitudinal member 110 and the transverse member 120 so as to ultimately increase the strength of the reinforcing member 100 as a whole.

3 and 4 relate to a first embodiment in which a longitudinal member 110 and a transverse member 120 are formed in a circular cross-sectional structure (a reinforcing bar or a steel rod having a circular cross-section), a single transverse member 120, So that the rectangular coupling portion 130 is formed.

5 shows a second embodiment in which the longitudinal member 110 is formed in a circular cross section (a reinforcing bar or a steel bar having a circular cross section), and the cross member 120 has a rectangular cross sectional structure (For example, by machining a reinforcing bar or a steel bar having a circular cross-section), one longitudinal member 110 is joined to one transverse member 120 to form the rectangular coupling portion 130.

The rectangular coupling portion 130 may be formed only at the front end of the transverse member 120 or may be formed at a plurality of points along the longitudinal direction of the transverse member 120.

An extension part 121 projecting forward from the rectangular coupling part 130 is formed at the front end of the transverse member 120. This has the effect of more relieving stress concentration on the rectangular coupling part 130. [

The rectangular coupling portion 130 is formed by various welding methods such as electric welding. It is preferable to quench the welding portion with a low-temperature gas immediately after welding in order to increase the strength.

In the case of quenching with liquid, air bubbles due to water vapor are generated at a high temperature point, so that the rapid cooling effect is reduced due to the effect of the warming effect. Therefore, it is preferable to use a low temperature gas.

In order to prevent oxidation, it is preferable to use a gas such as argon or nitrogen gas.

When the reinforcing member of the lattice structure is installed in the longitudinal insertion groove 11 and the lateral insertion groove 12 of the block 10 and is put in the long term use state, 10 protrude forward and a portion of the reinforcing member other than the engaging portion protrudes forward.

In the case where the reinforcement member 100 is machined by a structure in which a portion of the longitudinal member 110 other than the rectangular coupling portion 130 protrudes forward so as to adapt in advance to the deformation to be caused in the future, An advantage that it can be stably adapted to long-term deformation is added (Fig. 6).

Here, the longitudinal member 110 is preferably formed in a curved structure in view of preventing the occurrence of weak portions due to stress concentration.

The method of constructing the reinforced earth retaining wall according to the present invention is performed by the following process.

A plurality of blocks 10 having the longitudinal insertion grooves 11 and the transverse insertion grooves 12 are formed to form the surface structure.

The rear soil is installed at the rear of the block (10) and verified.

The reinforcing member 100 is inserted into the longitudinal insertion groove 11 and the transverse insertion groove 12 of the block 10 so that the projecting portion 110 of the reinforcing member 100 faces forward, (130) is positioned at the contact portion of the longitudinal insertion groove (11) and the lateral insertion groove (12) of the block (10).

Then, the above steps are repeated upward to form a retaining wall structure.

A block 10 having a structure in which a protruding portion 14 having a curved structure is formed in front of the support portion 13 of the block 10 forming the longitudinal insertion groove 11 and the lateral insertion groove 12 is manufactured and used The rear depressed portion of the projecting portion 110 of the reinforcing member 100 is stably fixed to the front projecting portion 14 of the supporting portion 13 so that a more stable coupling structure can be achieved (FIG. 7).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
