Abstract

Anchor connection-type revetment-retaining wall structure for preventing scour of a river embankment foundation is provided to prevent the foundation coming in contact with water from being scoured and collapsed and to prevent flood damage caused by collapse of the foundation. In anchor connection-type revetment-retaining wall structure for preventing scour of a river embankment foundation, a revetment-retaining wall(900) is installed to a river embankment while plural blocks are fastened to the foundation coming in contact with water with anchor bolts(600) and are fixed by fixing piles(700). A Y-shaped block(300), a T-shaped block(400), and a U-shaped block(500) are fixed with anchor bolts(600) and the fixing piles. Sealing members(570) are installed to cut-off holes formed in surfaces where the blocks are closely adhered. The Y-shaped block is formed in a Y-shape protruded to the opposed side of an incised side and cut-off holes(302), an anchor hole(304), and a pile-fixing hole(306) are formed along the longitudinal direction of the Y-shaped block. The T-shaped block is formed in a T-shaped section and plural cut-off holes(402), an anchor hole(404), a pile-fixing holes(406) are formed in the T-shaped block, which is inserted in the incised hole of the Y-shaped block. The central part of the U-shaped block is incised and a cut-off hole(502), an anchor hole(504), and a pile-fixing hole(506) are formed in the U-shaped block, which is combined to the protruded part of the Y-shaped block. The sealing members are inserted in the cut-off holes and are closely adhered. The anchor bolts and the fixing piles are inserted and fixed in the anchor holes and the pile-fixing holes.

Description

BREAST WALL STRUCTURE OF EMBANKMENT FOR RIVER}

The present invention relates to an anchor-connected raft retaining wall for preventing scouring installed on a river bank foundation. In particular, the present invention provides an anchor-connected raft retaining wall installed for the purpose of preventing scour on a river bank foundation. The present invention relates to an anchored revetment retaining wall structure for preventing river scour and foundation scour.

In general, a river reservoir is installed with a dike in order to protect the water supply in most cases, the river embankment 20, as shown in FIG.

The collapse of the river bank 20 causes large flood damage, requiring a new countermeasure to prevent the river bank 20 from collapse.

In view of the above, the present invention, the present invention, because the installation of the anchor retaining retaining wall on the river bank, preventing the problem that the foundation is in contact with the water is collapsed and collapse, thereby preventing damage to the water that can occur It is an object of the present invention to provide a riverbank foundation scour prevention anchoring revetment retaining wall structure that can be made.

The present invention, in order to achieve the above object, the present invention, in a river provided with a bank embankment axis in the river bank embankment, a plurality of blocks are fastened with anchor bolts on the ground in contact with water on the river bank embankment and fixed to the ground The retaining wall is installed to be fixed, while the Y-shaped block, the T-shaped block and the U-shaped block are fixed with anchor bolts and fixing piles, and the sealing member is installed in the water hole formed in the surface where each block is in close contact to prevent leakage. The revetment retaining wall structure is comprised by the structure which becomes.

Hereinafter, the configuration and implementation of the present invention will be described with reference to the accompanying drawings.

2 is a view showing a cross-sectional state of the anchor retaining bilge retaining wall is installed on the base of the river bank of the present invention, Figure 3 is a view showing the assembly concept of the anchor retaining raft retaining wall of the present invention, Figure 4 is an anchor connected raft of the present invention It is a figure which shows the disassembled state of a retaining wall.

As can be seen in Figure 2, the river 100 is installed on the embankment law surface 150 using a block of the embankment shaft 200, the base of the stream fixed to the block product fixed by the fastening anchor 600, pile 700 The retaining wall 900 is configured to be fixed by the.

As can be seen in Figures 3 and 4, the shore retaining wall 900, Y-shaped block 300, T-shaped block 400 and U-shaped block 500 is anchor bolt 600 and the fixed pile 700 It is fixed to, and is installed in a structure that blocks the leakage by the sealing member 570.

The Y-shaped block 300 is a roughly Y-shaped, one side is cut in the c-shape, formed to protrude on the opposite side of the cut, the exponential hole 302, anchor hole 304 and the pile along the longitudinal direction While the fixing hole 306 is formed, the Y-shaped block 300 is located in the middle of the T-shaped block 400 and the U-shaped block 500.

The T-shaped block 400 has a T-shaped cross-sectional shape, a plurality of exponential holes 402, anchor holes 404 and pile fixing holes 406 are formed, while the T-shaped block 400 is Y-shaped The block 300 is inserted into the cut surface of the c-shape.

The U-shaped block 500, the center portion is cut in the c-shape, the exponential hole 502, anchor hole 504 and the pile fixing hole 506 is formed, while the U-shaped block 500 is Y-shaped It is coupled to the protrusion of the block 300.

The Y-shaped block 300, T-shaped block 400 and the U-shaped block 500, the exponent hole 302, 402, 502 is formed in a circular shape on the surface in close contact with the sealing member 570 is inserted and tightly fixed, and anchor holes 304, 404, 504 and pile fixing holes 306 are formed in each of the Y-shaped block 300, the T-shaped block 400, and the U-shaped block 500. Anchor bolt 600 and the fixing pile 700 is inserted into the (406) 506 to be fixed.

The Y-shaped block 300, T-shaped block 400 and the U-shaped block 500, the sealing member 570 formed in the form of a circular rod is in close contact with each other, the Y-shaped block 300, T-shaped block An anchor bolt 600 is fastened horizontally to the 400 and the U-shaped block 500 and is fixed with a nut. The Y-shaped block 300, the T-shaped block 400, and the U-shaped block 500 have a fixed pile. 700 is installed so as to be vertically installed to secure each block to the ground.

As can be seen from the above-described configuration, the raft retaining wall 900, Y-shaped block 300, T-shaped block 400 and the U-shaped block 500 is installed to extend along the longitudinal direction in close contact with the structure Bars can be installed in the vicinity of the river to prevent scrubbing of the foundation of the river, thereby enabling the construction of a protection structure for the river bank foundation.

The effects that can be generated by the above-described configuration will be described below.

According to the present invention, since the revetment retaining wall is installed in a prefabricated form by combining Y, T and U-shaped blocks by anchor connection to the river bank, the river bank foundation in contact with water can prevent scouring.

In addition, it is possible to obtain an effect that can prevent in advance the flood damage that may occur due to the collapse of the river bank.

BRIEF DESCRIPTION OF THE DRAWINGS The figure which shows the problem of the conventional river bank foundation.

Figure 2 is a view showing a cross-sectional state is installed anchor anchoring retaining wall on the river bank foundation of the present invention.

3 is a view showing the concept of assembly of the anchoring retaining wall retaining wall of the present invention.

4 is an exploded view of the anchored retaining wall of the present invention.
