Description

Landscape block type pressure grouting anchor device

The present invention relates to a landscape block type press grouting anchor device for aesthetically decorating a landscape of a slope formed by construction and firmly reinforcing an inner ground of the slope.

More particularly, the present invention relates to an improved method for effectively reinforcing the perturbed ground by more effectively filling the grout material to the loosely perturbed portion in the process of forming the insert hole for the anchor device insertion in the ground of the formed inclined surface And a pattern layer representing an aesthetic appearance on the outer surface of the block body portion inevitably protruding from the inclined surface in order to support the tensile state of the anchor device.

Generally, an insert hole is formed in the ground of the inclined surface which can firmly hold an inclined surface formed obliquely by construction, and an anchor is inserted and fixed in the insert hole.

When the grout material is filled in the anchor inserted in the insert hole, the grout material is hardened and the anchor is integrally connected with the insert hole to firmly maintain the structure of the ground formed with the insert hole.

When the anchor inserted in the insert hole structurally stabilizes the inclined surface by hardening the grout material, a landscape forming work is performed to decorate the appearance of the inclined surface. Here, the landscape forming work is a completely new process from the operation of inserting and fixing the anchor into the insert hole, and generally, the inclined surface is formed in such a manner that the inclined surface is completely covered with an artificial stone or the like.

As such, if the anchor is inserted and fixed in the insert hole and the landscape construction work to completely cover the inclined surface with the artificial stone, the construction cost is greatly increased and the construction period is increased accordingly.

Here, in order to reduce the construction cost, there is a problem that only the rigidity due to the insertion of the anchor is satisfied on the ground of the slope, and if the slope is left unchanged, the aesthetic effect may be adversely affected.

As for the construction of the anchor device with respect to the ground of the inclined plane, depending on the construction method of filling the grout material and the configuration of the anchor for filling the grout material, the ground anchor in the cured state in the insert hole has remarkable durability and rigidity Will be different.

For example, when foreign substances generated from the inner wall of the insert hole are drawn into the inner side of the anchor before the grouting material filling the insert hole is cured, incomplete curing of the grout material introduced into the anchor from the outside occurs, resulting in poor durability and rigidity .

For this reason, the filling technique of the grout material through the structure of the anchor or the anchor is an important issue for the ground reinforcement work.

On the other hand, in order to insert the ground reinforcement anchor, the insert hole is first formed. In the process of forming the insert hole, usually, high pressure air is sprayed on the ground to form a space. At the same time, Use the method to solve.

Since the insert hole is formed while spraying the high-pressure air in this way, the inner diameter of the insert hole is unevenly formed, and an air passage due to suction is generated from the inner wall of the insert hole so formed to the deep part of the ground, The disturbance occurs.

For this reason, the hardness of the ground shows the result of the difference according to the construction method of injecting the grout material after inserting the anchor into the insert hole. In this case, the construction method of injecting the grout material is largely dependent on how the anchor is structured, so how to adopt the anchor structure is most important.

It is an object of the present invention to provide a landscape block type press grouting anchor device capable of simultaneously performing an anchor grouting operation for a sloped ground and a landscape forming work for decorating an appearance of a slope at one time have.

Depending on the ground condition of the construction site, there is a lot of water or there is a possibility that the soil may flow. If foreign matter flows into the inside of the insert hole (10) or the outer pipe (100), foreign matters are mixed separately in the grout material The backflow prevention check valve 200 can prevent the above problem by blocking the backflow of the backflow prevention check valve 200. As a result,

The backflow prevention check valve 200 is a double check valve capable of spraying the grout material at a high pressure to the insert hole 10 corresponding to the free space 12 through the outer tube 100 corresponding to the free anchor portion 120. [ .
