Description

Chiropractic four-way diffusion anchor assembly

The present invention relates to an azimuth type four-way anchor assembly, and more specifically, to reinforcement by movement of a vertical movement ring moving upward by grout injected into an anchor head of an anchor assembly inserted into an anchor hole formed in a soft ground or the like. Fixing pin is configured to be completely fixed by the grout is injected into the anchor hole.

In general, anchors are used to prevent the collapse of incisions in arthropods, to stabilize slopes, to prevent injuries caused by groundwater in large structures such as buildings or dams, and to prevent the collapse of excavated walls in underground construction of large buildings. In order to prevent the movement or distortion of the construction when constructing a large steel tower.

In this anchor method, the anchor hole is drilled in the ground where there is a risk of collapse, and the grout hose, the plurality of tension members, and the inner body are inserted into the anchor hole as one unit, and then grout is injected through the grout hose. When the injected grout is cured together with the lower body, the fastener is fastened to the other end of the tension member and the tension member in the strand is tensioned using hydraulic equipment to stabilize the target structure.

Prior art for such an anchoring method is registered Patent No. 10-1805170 (name of the invention: a composite anchor assembly having a frictional tension and wedge acupressure fixing unit and its construction method), Patent No. 10-1360721 (name of the invention: Construction method of the removable ground grout anchor for the soft ground using the inner body equipped with the expandable wing) and Patent No. 10-0598024 (name of the invention: wedge anchor) are provided.

Such a composite anchor assembly having a frictional tension and a wedge anchorage fixing part of the prior art and a construction method thereof include: an anchor head inserted into a boring hole in the ground; An acupressure unit installed on the ground at a position corresponding to the boring hole of the ground; One side is coupled to the anchor head, the other side is configured to include an anchor body provided with a strand wire coupled with the acupressure unit, while being able to be stably fixed in the perforated hole formed in the solid weathered soil and weathered rock ground, not soft ground, The effect of maximizing the area to be settled in the boring hole of the ground is provided.

However, in the prior art, when the coated steel wire is tensioned, the inner body rises inside the split blade of the split blade, and the split blade opens downward around the bottleneck to be coupled to the wall of the perforation hole, thereby causing a decrease in the bonding force when the steel wire is stretched. It became.

In addition, the construction method of the removable ground grout anchor for the soft ground using a load bearing body equipped with the expandable wing of the prior art, the wedge resistance of the expandable wing is automatically unfolded by the restoring force of the spring and inserted into the ground, The pressure resistance of the enlarged bulb formed by filling the grout into the enlarged space increases the pullout resistance and minimizes the loss of tensile force after stretching.In addition, in the soft ground, the additional surface of the packer increases the frictional force of the principal surface, thereby increasing the pullout resistance. There is an effect to increase.

However, this prior art forms a drilled hole in the ground using a casing, injects grout into the casing, inserts the anchor assembly inside the casing, and pulls the casing from the outside, thereby leaving the casing from the drilled hole and simultaneously anchoring. It is a structure in which the expandable wing of the assembly is expanded by the restoring force of the wing spring and intrudes into the ground.It has a structural problem that requires the use of a casing in order to operate the expandable wing, and an expandable wing in which the anchor assembly is supported by the wing spring. Because of the complexity, the operation is not easy.

In addition, the wedge-type anchor of the prior art does not depend on the bearing pressure of the grout, but is naturally opened by the drawing of the case when the tension member is tensioned, and the anchor blades that are embedded in the ground and apply the compressive force generate the support rigidity against the ground. Even in the case of joints or soft ground, it can effectively reinforce the ground, preventing accidents and shortening the construction period.

However, this prior art is a structure in which the anchor wing that moves backward with the case unfolds outwardly around the hinge pin while being pushed to the rear by the tension of the tension member and is embedded in the ground. It is a problem that the anchor wing is not easy to operate around the hinge pin inside the ball.

The present invention has been made to solve such a conventional problem, the object of the present invention is to move to the top of the anchor head by the grout injected into the anchor head of the anchor assembly inserted into the anchor hole formed in the soft ground, etc. It is to provide an acupressure-type four-way anchor assembly configured to be completely fixed by the grout injected by the reinforcing fixing pin is diffused into the anchor hole by the movement of the vertical movement ring.

The problem solving means for achieving the above object is a vertical in which the inclined portion formed in the lower portion and the inclined portion integrally formed in the upper portion of the anchor hole to facilitate the insertion, and the plurality of discharge holes through which the grout or air is discharged on the outer circumference thereof. Anchor head is made of a portion, the connector is formed in which the screw hole is formed in the bottom center area protruding fixed; Acupressure unit provided on the ground outside the anchor hole; A steel wire fixing member having an injection tube formed with an injection hole into which a grout or air is injected into the anchor head by screwing a lower portion into the screw hole of the connector, and a through hole coupled to the upper portion of the injection tube through a central region; The lower part is fixed to both sides of the coupling through-hole of the member, and a plurality of strands of which the upper part is fixed to the acupressure unit, and is fastened and fixed by fastening bolts so that the lower part communicates with the upper part of the injection pipe, and the upper part is located outside the anchor hole to grout. Or an anchor body consisting of an injection hose for injecting air; It is characterized by consisting of a diffusion fixing member which is movably coupled inside the anchor head and is moved upward by the grout or air injected from the outside so as to be closely adhered to the inner circumferential surface of the anchor hole and fixed by the grout.

According to the present invention, the vertical movement ring is pushed to the upper part of the inner circumferential surface of the anchor head by the injection pressure of the grout injected into the anchor head constituting the anchor assembly inserted into the anchor hole formed in the soft ground. The diffusion operation into the anchor hole is made precisely and easily, and at the same time, the grout discharged into the anchor hole is discharged into the anchor hole through the discharge hole of the anchor head opened by the vertical moving ring which is moved upward. The construction is excellent, and as the injection of grout or air into the anchor head, as it is diffused upward on the reinforcing fixing pins, the diffusion operation of the reinforcing fixing pins in the anchor hole as compared to the structure to tension and diffuse the tension material of the prior art. The effect of knowing that this is done is provided.
