Description

Set Anchor for Slope Reinforcement

The present invention relates to a connection fixture for slope reinforcement, and includes: a rock nail or grid installed on the slope for reinforcement, and a rock including a set anchor 110 installed on the rock 40. In the connecting structure used to connect between the fixing structure 50, the thread forming portion 105 formed at one end of the rock fixing structure 50 protruding out of the rock 40; And, One end is connected to the connection member 60 of the soil nail (grid) or grid (grid), the other end of the connecting rod member 130 is formed with a first threaded portion 131; and the thread forming The first through-hole 121 is formed to be inserted and fixed by the nuts 140a and 140b, and the first threaded portion 131 is inserted to be fixed by the nuts 140c and 140d. And a connection plate 120 having a second through hole 122 formed therein. Slope reinforcement for connection, characterized in that relates the identity (100).

Civil engineering or construction sites generally need to consider reinforcement of the cut surface of the cut formed by cutting the rock or the ground, or the slope of the fill section with respect to the cut created between the different altitudes in the process of laying the ground. .

Such cuts or fills are also called slopes, and the cuts are structures for inclined surfaces having inclinations formed by arbitrary incisions, and the fills are structures for inclined surfaces formed at high elevations during the filling process.

Here, the cutting surface and the inclined surface may be presented a construction method for reinforcement in various ways. Among them, the reinforcement method should be applied to the cut section considering the landscape considering the external aesthetics as well as safety and economy.

In general, in order to reinforce the inclined surface of the cut portion, a retaining wall structure using concrete pouring or a stone wall structure using mountain stones (natural stone) may be presented.

However, the retaining wall structure using concrete pouring lacks flexibility and variability corresponding to shapes of slopes and rocks to be installed. And a support base is needed to solve the flexibility and variability, but a considerable space is required to secure the support base. In addition, the securing of such space requires a lot of backfilling work, and thus the construction period is extended, and construction costs are high. In addition, when a partial breakage of the retaining wall structure occurs in the future, repair thereof is difficult, and it is difficult to satisfy the landscape aspect in consideration of aesthetics.

On the other hand, in the case of the stone wall structure using natural or artificial stone, the landscape aspect can be satisfied, and flexibility and variability corresponding to the inclined surface can be secured, but it is difficult to maintain the natural stone in an upright state when stacking stones, If you are not an experienced contractor there is a problem that natural stone can be easily collapsed.

In order to solve the problem of the stone wall structure, there is a need for a connecting fixture that connects while maintaining tension between rocks such as natural stones and support structures such as soil nails or grids installed on slopes. Existing inventions related to such connecting fixtures include a construction method such as "Landscaping facility construction method and landscaping facility structure using blasting stone" disclosed in Patent Document 1 (Korea Patent Publication No. 10-2003-0086233). It has been proposed and implemented.

In the invention of Patent Document 1, in relation to the construction of the incision site, between the nail nail installed in the incision in Fig. 2 and the three anchors installed in the blast stone to fix between the three anchors installed in the blast stone The structure using the wire member by which both ends are clamped by the clamp is disclosed.

As a configuration similar to such a configuration, a configuration similar to that of FIGS. 5 to 8 is also disclosed in the "retaining wall using mountain stone (Korean Patent Publication No. 10-2009-0007144)" disclosed in Patent Document 2.

However, in the case of the connecting fixture using the wire member in this way,

1) It can support the tension to be pulled, but it cannot support the pushed or pressed response.

2) It is impossible to adjust the distance to fix the connection by itself, and in order to adjust the connection fixed distance, a component such as a separate connection ring as shown in Figure 5 of Patent Document 2,

3) Since only the clamping of the wire member with a clamp or the like, the strength of the bond is relatively weak, the bond is easy to loosen,

4) Once the wire member is fixed with a clamp, etc., it is necessary to rotate the connecting ring in order to adjust the distance for fixing the connection. In this case, however, the wire member is twisted. There was a problem that it was impossible to adjust.

In order to solve the problems of the existing invention, a construction method such as "environmentally friendly retaining wall structure disclosed in Patent Document 3 and its construction method (Korean Patent No. 10-0657773)" has been proposed and implemented. In invention of the said patent document 3, the structure of an anchoring part using the rod-shaped connection fixing body which has rigidity as shown in FIG. 4 by the structure of a connection fixing body is disclosed.

However, in the case of the invention of Patent Literature 3, among the problems of Patent Literature 1 or Patent Literature 2 in that the support for stress as well as tension can be supported by the configuration using a rod-shaped connecting fixture having rigidity. The problem of 1) was solved, but the coupling between the main anchor / front auxiliary anchor / rear auxiliary anchor constituting the anchor part is only fixed by welding or by using a clamp or the like. There existed a problem that the problem of 2) -4) of the problem of patent document 2 still remains.

Patent Document 1: Republic of Korea Patent Publication No. 10-2003-0086233 Patent Document 2: Republic of Korea Patent Publication No. 10-2009-0007144 Patent Document 3: Republic of Korea Patent No. 10-0657773
