Description

Nail anchors for slope reinforcement {anchor-nail for slope-reinforcement-construction}

The present invention relates to a nail anchor for slope reinforcement, and more particularly to a nail anchor for slope reinforcement to improve the productivity and workability of tomorrow's anchor by developing the anchor blade of the nail anchor with the force of the punching machine used in the same place. will be.

As the industry develops, it is inevitable to develop slopes such as mountain roads such as foundation roads and complexes. Currently, the sliding reality of slopes is constantly occurring regardless of time and place, and acts as a threat to life and property. Doing

For this reason, the soil-nailing method is most widely used as a stabilization method for suppressing the collapse and sliding of the slope.

Here, the soil nailing is to install a reinforcement (nail structure) on the ground to form a composite reinforcement while maximizing the strength of the ground, thereby increasing the shear and tensile strength of the ground to suppress displacement and to prevent ground loosening It is a construction method.

In other words, the basic design concept of the soil nailing method is that the ingot of the area reinforced by the nail structure maintains stability on any slope that the reinforced earth wall can assume by acting as an integrated retaining wall. .

Such small nailing has been used for temporary earthquake structures, foundation burrows, etc., but in recent years, its application has been expanded to include slope reinforcement of roads, rock reinforcement of railways, dams, and tunnel shafts.

However, this small nailing is a combination of rock, which is designed to be useful for soil, and the rock structure of various slopes is different from soil, and the rock has a lot of joints, rock with many joint layers, and heat deterioration under the influence of monolayer. Many slopes, such as rocks separated from the mother rock due to the development of discontinuities due to the blasting, are unstable in structure, so reinforcing the rock slopes using only existing nail structures has a problem that can be followed.

The present applicant has applied for a nail anchor (application number 10-2002-0072035) to improve the slope reinforcement by allowing the nail tip to be fixed to the birthmark during construction by a simple method and device.

This is an example of the anchor body (3) including the anchor blade (2) which is fixed to the drill hole (1) for slope reinforcement work as shown in Figures 1 and 2 and the anchor blade (2) in the anchor body (3) The tapered body 4, which is expanded and pressed into the punching hole 1, is inserted into the nail 5 so that the taper body 4 is advanced by the coupling force when the nail 5 and the anchor body 3 are screwed together. By extending the blade 2, the nail tip is fixed to the punching hole (nevus) through the anchor body 3, and the post process such as grouting is performed on the nail 5 fixed in the punching hole 1. It is.

In addition, the anchor body (3) for performing this is formed deformation neck (6), the wedge projection (7) is formed so that the rotation of the anchor body (3) is prevented during the rotation of the nail (5).

Through such nail anchors, the nail anchors are fixed to the birthmarks before the grouting construction by simple construction, and the tensile strength is increased by fixing force through the anchor blades, thereby improving the slope reinforcement.

By the way, in the nail anchor used together with the anchor body (3) and the nail (5) in combination with the expansion of the anchor blade (2), using the screwing force, the use of a separate tool by the processing of the screw thread and the use of the screwing force Therefore, there are matters to be improved in terms of productivity and convenience of construction.

To explain this in more detail, first, when the construction is performed by the punching machine (not shown) to the birthmark, and then insert the anchor body (3) and the nail body (5) combined with the drilling hole (1), the rotary tool ( Not shown) is used to rotate the nail (5).

At this time, the rotary tool is inconvenient to use as a manpower to expand the anchor blades by using the pneumatic rotary mechanism to the combined force, there is an inconvenience to use a separate rotary mechanism separately from the perforator during construction.

In particular, the drilling process and the mounting process of the nail anchor is weak in the connection of the process according to the dualization of the installation mechanism, it was inconvenient to construct in consideration of the process flow for shortening the process.

On the other hand, in order to expand the anchor blade (2) must be carried out the pressing screw surface (8) processing on the nail, and the anchor body (3) to be coupled to the anchor body (3) because the screw thread processing, anchor body that does not require much precision (3) In the production of), precise threading had to be performed.

Therefore, such thread machining had to be improved in terms of productivity improvement of the anchor 3 tomorrow.

Therefore, the present invention has been devised to improve the above problems, the use of a perforator in the expansion of the anchor blade to improve the connection of the process, and also to remove the thread processing of the nail anchors to improve the productivity of the anchors tomorrow slope nails for use The purpose is to provide an anchor.

The present invention for this purpose is to allow the nail and the anchor body to be coupled to the separation prevention, etc., and to insert the nail anchor coupled to the drilling hole, to use the hydraulic blow force of the drilling machine to expand the anchor blade through the drilling machine. will be.

Various changes and modifications are possible within the scope without departing from the technical spirit of the present invention, as well as other embodiments that are equally clear.

Exemplary drawings FIG. 3 is a facility name diagram showing a nail anchor according to the present invention, Figures 4 and 5 is a facility name and cross-sectional view for explaining the operating state of the nail anchor according to the present invention.

According to the present invention, a drill hole 1 is formed on a slope through a puncher, and a nail anchor screwed with an anchor body 3 including a nail 5 and an anchor blade 2 is inserted into the drill hole 1. Next, the nail 5 is rotated with a rotary tool to advance the tapered body 4 by the uncoupling force with the anchor body 3 to expand the anchor blade 2 to fix the anchor blade 2 on the birthmark, and then grouting. Unlike conventional slope reinforcement nail anchors that perform,

Insert the tip of the nail 10 into the anchor body 12 and then temporarily fix the nail 10 to prevent separation of the nail 10 from the anchor body 12, and then insert the temporarily formed nail anchor into the hole 1. Slope reinforcement for fixing the anchor blade (2) to the birthmark by expanding the anchor blade (2) by hitting the rear end of the nail 12 with a punching force to advance the tapered body (4) with its striking force Provide nail anchors.

That is, the present invention is a nail (5) formed with a pressing screw surface (8) and the tapered body (4) fitted to the nail (5) and the screw threaded with the pressing screw surface (8) and is advanced by the screwing force In the four-side reinforcement nail anchors consisting of an anchor body (3) having an anchor blade (2) extending by the tapered body (4), the anchor blade (2) according to the advance of the tapered body (4) by the impact force of the perforator An insertion protrusion having a length through which the anchor body 12 penetrates the anchor body 12 and includes an advance distance providing an expansion of at least the anchor blade 2 and at least the anchor blade 2 formed with the through-hole 14 is performed. Slope consisting of a nail (10) having a 16 and the separation prevention mechanism (18) which is coupled to the tip of the insertion protrusion and interferes with the anchor body 12 to prevent the nail 10 from being separated from the anchor body 12 Reinforcement nail anchor.

Here, the departure prevention tool 18 is characterized in that the pin hole 20 is formed at the tip of the nail 10 and the pin 20 is coupled thereto so that the nail tip and the anchor body interfere with each other.

On the other hand, the escape prevention tool 18 is another embodiment as shown in Figure 6, the threaded line 24 is processed at the tip of the nail 10 and the nut 26 is coupled to the threaded line 24, the nail end and the anchor body interferes It is characterized by one.

As described above, the present invention provides a simpler construction method and a nail anchor structure to provide a nail anchor technique and a nail anchor with improved workability and production line.

The present invention for this purpose is to improve the productivity of the anchor body (12) and nail (10) by improving the existing screw coupling, and to prepare a separate device for the screw coupling during construction and to perform a dual process as a perforator .

That is, the perforator is mainly to perform the perforation to the birthmark, but its hydraulic striking force is also possible as an application for expanding the anchor blade.

Through this construction, by forming a punching hole (1) and a nail anchor anchoring process in one construction, it is possible to shorten the air while providing a connection of the process and more convenient process.

This is made possible by the improvement of the nail 10 and the anchor body 12 which have a simple and great meaning as mentioned above.

That is, the anchor body 12 and the nail 10 according to the present invention, unlike the conventional nail 10 is simply inserted into the anchor body 12, and then anchored with the anchor body 12 by the escape prevention mechanism 18 Sums up.

The temporary coupling of the nail 10 so as not to be detached from the anchor body 12 is to transfer the nail 10 and the anchor body 12 separately when the nail 10 is easily detached from the anchor body 12. This is because it is uncomfortable and the inconvenience that the nail 10 is separated from the hole (1) due to its own weight in the upward construction.

Insertion protrusions 16 are formed in the nail 10 to prevent such detachment, and the insertion protrusions 16 of the nails are inserted through the through holes 14 of the anchor body 12 and then the release prevention holes 18. Is fastened to prevent the departure of the nail (10).

On the other hand, since the tip of the nail 10 protrudes from the exit of the anchor body 12 by the coupling with the escape prevention mechanism 18 and the nail advances due to the blow through the perforator and the expansion of the anchor blade 2, the wedge The projections preferably have a length that will provide sufficient protrusion and travel.

Therefore, the conventional wedge protrusion is not a structure for preventing the rotation of the anchor body 12 at the end of the drilling hole 1, but a space that provides a separation distance for advancing the tip of the nail 10 in the anchor body 12. It serves as a support 28.

Thereby, the anchor body 12 of the present invention is spaced apart from the end of the drilling hole (1) is characterized in that the spaced apart support 28 is provided to provide the total distance of the nail tip (1) when hitting the nail (10).

On the other hand, the release prevention mechanism 18 is for temporarily coupling the nail and the anchor body as described above, can be realized as a general means, and the present disclosure is not limited to the release prevention mechanism shown.

In general, however, a pin or bolt coupling may be preferably applied.

That is, when the pinhole 20 is formed in the insertion protrusion 16 that is the nail tip and the pin 22 is coupled thereto, the tip of the nail 10 inserted into the anchor body 12 and the anchor body 12 penetrate through the pinhole 20. The exit of the hole is interfered to restrain the tip of the nail (10).

On the other hand, when the thread 24 is processed at the tip of the nail 10 and the nut 26 is coupled thereto, the nut 26 interferes with the outlet of the through hole 14 to restrain the tip of the nail 10. will be.

The thread 24 here is different from the thread described in the prior art, which is not only for the expansion of the anchor blades 2 through the tightening force, but also only at the tip of the nail 10 for engagement with the standardized nut. It is because it is formed.

The temporary coupling of the tip of the nail 10 and the anchor body 12 does not affect the securing of the tension force of the nail anchor, because the nail anchor is coupled to the punching hole by grouting when the grouting is poured afterwards. .

According to the present invention as described above, by using the punching force of the punching machine in combination to fix the nail anchor on the birthmark, not only the construction is easy, but also the effect of improving the productivity of the nail anchor by eliminating the machining of the screw thread for coupling the nail and anchor body There is.
