Description

Multipurpose permanent anchor

The present invention is a perforated hole excavated with an excavation bit to supplement and prevent slope collapse for each slope (slope) due to cutting of the soil, cutting of rock slopes, and prevention of natural slope landslides in civil engineering and building construction By inserting and installing the wire or nail body, one end is connected to the anchor, and the other end is fixedly coupled to the acupressure plate provided on the slope surface to apply tension to the acupressure plate to prevent sliding of the slope, and at the same time, the anchor is drilled A plurality of retractable rotating fixing members are formed on the outer periphery of the anchor so that they are firmly coupled without being separated from the hole, so that the rotating fixing member is fixed and fastened to the part drilled from the bottom of the perforated hole to a predetermined position. It relates to a multi-purpose permanent fixed anchor device that prevents the anchor from being separated from the drilling hole even with the same strand or nail tensile force.

In general, in civil engineering and building construction, various slope reinforcement for slope reinforcement in order to supplement and prevent slope collapse for each slope (slope) due to cutting of the soil, cutting of rock slopes, and prevention of natural slope landslides Anchors for dragons were developed and provided.

As the industry develops, it is inevitable to develop slopes such as base roads or complexes, etc., and the current sliding reality of slopes is constantly occurring regardless of time and place, and acts as a peripheral element that threatens life and property. is doing

Therefore, the most widely used stabilization method for suppressing the collapse or sliding of the slope is the anchor method using a stranded wire such as a wire.

Here, the ankara hamper is a method of suppressing displacement and preventing the loosening of the ground by increasing the shear and tensile strength of the ground by forming a composite reinforced ground while maximizing the strength of the original ground by installing a pressure plate or a support plate in the original ground.

That is, the basic design concept of the anchor method is to maintain stability on any slopes that the reinforced earth wall can assume because the earth in the area reinforced by the acupressure plate acts like an integrated retaining wall.

Such anchors have been used for temporary retaining structures and excavation of foundations, but in recent years, their application targets such as slope reinforcement of roads, railroads, dams, and rock reinforcement of tunnel shafts are becoming wider.

However, this anchor is a graft of an anchor designed to be useful for soil to the bedrock. The rock structure of the various slopes is different from that of the soil bed, and the rock with many joints, rock with many cavities, and heat deterioration under the influence of faults, resulting in vulnerable bedrock and blasting. Because discontinuous surfaces developed under the influence of

In the existing case, the slope reinforcement structure was installed by inserting an anchor with a wire into the drilling hole and pulling the anchor to catch the ground or rock, and then fixing the wire to the acupressure plate. There was a problem in that the old anchor was pushed from the ground, and the tensile force of the wire was lost and sliding occurred on the slope of the ground.

Looking at the prior registration technology in this field, the wedge-type anchor of Patent Publication No. 0598024 includes a fixing head inserted into the anchor hole; a hollow casing disposed behind the fixing head; at least one tension member inserted into the casing, a front end fixed to the fixing head, and a rear end connected to acupressure means outside the anchor; And, it includes a packer installed on the outer peripheral surface of the rear end of the casing, and a wing support ring that is slidably coupled to the periphery of the casing; One end is rotatably connected to the periphery of the casing, moves together when the casing is moved, and the free end is spread by the wing support ring and one or more anchor wings are wedged into the ground around the anchor hole. do. In Patent No. 0598024 configured in this way, when the tension member is pulled after inserting the anchor into the drilling hole, the fixing head is pulled and the wing connection part is moved to the hole entrance side and the wing support ring does not move. It is configured so that the anchor wing supports the inner wall of the drilling hole by spreading it by Although the anchor wings are opened, there is a problem in that the anchor cannot be unfolded because the packer is pulled together by the pulling of the tension member. That is, the anchor having a wire-type tension member does not perform grouting, but spreads the anchor wings inside the drilling hole to hang on the inner wall of the drilling hole, and the tension member connected to the fixing head is pulled and fixed by the acupressure plate installed at the entrance of the drilling hole to be a tension member. In the configuration in which the wire is continuously pulled to bind the ground, Patent No. 0598024 has a problem in that when the ground starts to slide, the tensile force of the tensile member drops to zero, and the ability to resist vertical load or slope load is of no use at all.
