Description

[0001] APPARATUS FOR HOLDING A WIRE STRAND OF ANCHOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor steel strand holding apparatus installed through an underground continuous wall and more particularly to a steel strand holding apparatus for anchor steel strand holding apparatus, To an anchor steel strand holding device capable of imparting a tensile force over the entire length of strands.

As widely known, the construction of the diaphragm walls or slurry walls constructions for the trenching works is mainly used to prevent the collapse of the section and the penetration of the groundwater, Because it is used for earth wall, it is easy to maximize the land utilization rate according to the progress of construction technology and equipment, and it is possible to form a safe wall with high rigidity with low vibration and low noise in a densely populated area in urban areas. It is also used as a wall.

Such an underground continuous wall method uses a stabilizing liquid such as bentonite to prevent the collapse of the excavation wall while excavating a trench of a predetermined shape in the ground, inserting a reinforcing net thereon, pouring concrete and curing Continuously construct an underground continuous wall.

In this way, the underground continuous wall is constructed as a shape for the trenching work, and then the trenches inside the partitioned by the underground continuous wall are dug out and carried out. At this time, the support structure for supporting the lateral earth pressure of the underground continuous wall is strongly supported Construction. A strut support system and an anchor support system are used for such a support structure.

As shown in FIG. 1, the anchor support system is a structure in which a straight sleeve (2) for building a perforation hole (1) is slantingly provided at a predetermined angle in a reinforcing network of an underground continuous wall A perforation hole 1 is formed in each of the sleeves 2 by using a perforator in the process of constructing the underground continuous wall 3, The strands 6 of the anchor 5 are inserted into the perforation hole 1 through the sleeve 2 and grouted so as to fix the anchor body 8 of the anchor 5 in the perforation hole 1, And reinforcing the ground by tensioning the strands 6 of the strand 5 in the longitudinal direction.

At this time, the sleeve (2) is provided with a packer (7) for cutting off the water flowing through the perforation hole (1) in the ground. This order packer (7) is a double tube type in which both ends are clogged, and a through hole is formed in the center portion thereof.

The order packer 7 is inflated by injecting the grout 7a into the order packer 7 in a state where the strands 6 of the anchor 5 are passed through the center hole of the order packer 7, 7 are in close contact with the outer peripheral surface of the bundle of stranded wires 6 and are closed while the outer peripheral surface of the secondary packer 7 is in close contact with the inner peripheral surface of the sleeve 2. [

 As the grout 7a injected into the secondary packer 7 is cured, the upper portions of the strands 6 inserted into the secondary packer 7 are fixed in the secondary packer 7 in a sealed state. The water in the ground can be prevented from leaking through the inner space of the sleeve 2 by this order packer 7.

However, according to the conventional anchor supporting method, the stranded wires 6 of the anchor 5 are heavy and are bent to some extent in the longitudinal direction. Even when inserted into the perforation hole 1 through the sleeve 2, And the strands 6 of the anchor 5 are inserted into the order packer 7 in the sleeve 2 even if the grout is injected at a predetermined pressure into the sleeve 2, The strand 6 is fixed by the order packer 7 in a state in which the strand 6 is positioned almost intact on the lower bottom of the sleeve 2 without going up to the central portion of the sleeve 2. [

In this state, the grout is pushed and cured in the perforation hole 1 through the grout hose (not shown) which forms one bundle with the strands 6 of the anchor 5, so that the anchor 5, The upper ends of the strands 41 in the bracket 13 fixed to the flange 11 of the sleeve 10 are pulled and tensioned by a strand tension device (not shown) after the sieves 8 are fixed by the grout To fix the upper ends of the stranded wires 41 using the wedge assembly 14 and the stranded wire fixture 12.

Since the upper ends of the stranded wires 6 are drawn and pulled in a state of being folded by the order packer 7 when the upper ends of the stranded wires 6 are pulled and tightly fixed, it is not possible to obtain a function as an anchor without being tense over the entire length of the stranded wires 6. [ .

It is also more likely to be tense only at the strand portion located between the order packer 7 and the wedge assembly 14, thereby locally concentrating the tension on the strands 6 of the portion of the order packer 7, There is a problem that it is difficult to remove the strand when the strand is cut.

In addition, in the conventional anchor supporting system, the grout is not uniformly injected into the order packer 7 when the grout is injected into the order packer 7 as the strand 6 is sagged from the center to the bottom of the order packer 7 There is a problem in that water or grout or the like is leaked from the perforation hole 1 in the ground due to deterioration of the order performance which is a function of the order packer 7.

Particularly, in the conventional anchor supporting system, since the strand 6 and the grout hose (not shown) of the anchor 5 form a bundle and are simply passed through the through hole of the order packer 7, The gap between the outer surface of the grout hose and the outer peripheral surface of the grout hose tends to leak through the clearance between the outer surface of the grout hose and the outer surface of the grout hose, .

In addition, since the strand 6 and the grout hose can not catch the inner main surface of the order packer 7, both ends of the order packer 7 are convexly projected like a hemispherical shape. The jumping phenomenon has a problem that the function as the order packer 7 is inevitably reduced because the stranded wire 6 and the grouting hose as well as the main inner surface of the sleeve can not be pressed and adhered more effectively.

Disclosure of the Invention The present invention has been researched in order to overcome the above-mentioned problems, and it is an object of the present invention to provide a method for preventing the collapse of stranded wires and grout hoses in the under- And to provide a uniform tensioning force over the entire length of the strands of the anchor.

In addition, since the present invention is a structure in which the air gap preventing member is disposed on the outer main surface of each strand and the grout hose and is disposed in the through hole of the secondary packer, when the strands are inserted into the through hole of the secondary packer, Which is elastically deformed while the outer surfaces of the anchors are in contact with each other, thereby preventing voids from being generated between the outer major surfaces of the strands.
