Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of constructing a slanting wall formwork using a fixed module for mounting sloping slopes,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of constructing a mold, and more particularly, to a method of constructing an inclined reinforced concrete wall formwork using a fixed module for mounting a slope.

In order to stabilize unstable slopes, a variety of slope reinforcement methods have been implemented. Especially, in the case of a slope of a slope or a slope made of a rock, etc., a concrete retaining wall method is proposed in which a concrete structure is constructed in the form of a retaining wall to support a slope Or a separate shotcrete method is applied.

Hereinafter, some forms will be described in the conventional slope reinforcement method, especially the die making method.

1 is a view schematically showing a form in which a mold is installed on an inclined outer wall for a concrete retaining wall according to the prior art.

As shown in the figure, when the land of the slope is a soft ground, the mounts 11, which are similar to the anchors, are installed at predetermined intervals on the slopes.

At this time, one end of the cradle 11 is inserted and fixed in a substantially perpendicular direction to the slant, and a plate-shaped form 13 is bolted to the cradle 11 at the other end of the cradle 11, A fixing member 15 for fixing the fixing member 15 in the manner of FIG.

Then, after placing the concrete between the slope and the mold 13, if the concrete is completely hardened after a predetermined time, the concrete mold 13 is removed to complete the concrete retaining wall.

Meanwhile, in the case of the mold construction method of this type, the cradle 11 may be easily detached from the slope due to the pouring pressure of the concrete when the concrete is poured, and the installation state of the form 13 may not be stable There was a case.

FIG. 2 is a schematic view of a form in which a form is placed on a sloping topography according to the prior art.

The shotcrete S can be performed on the slope surface in advance so that the cage 21 can be more firmly fixed to the slope even in the case of the soil or rock area having a steep slope or the soft slope as shown in Fig. .

When the shotcrete (S) is completely hardened, the drilling operation is performed at predetermined intervals. Thereafter, the drilling operation is performed at a position where the drilling operation is performed. (21) is inserted and fixed using a separate resin or cement paste.

FIG. 3 is a view for explaining a problem in the case where the shotcrete is not uniform in FIG. 2. As shown in FIG. 3, when the defect of the shotcrete or the skill of the worker is insufficient, the shotcrete S is applied to the surface of the slope There is a number. Particularly, in some areas, a portion where the mounting table 21 is fixed may be thinned.

In such a case, some of the cradles 21 can not assure the reliability of the fixing state, which degrades the stability of the form itself, thereby adversely affecting the formation of the retaining wall finally constructed.

In addition, even if the shotcrete application form has a sufficient height as a whole and stably applied, a separate drilling operation is required to form a joint hole for insertion of the mount, and in order to form such a drilling operation, There is a problem in that the installation of electric devices is required and also the fixing time of the cradle is required to apply the resin or the cement paste to fix the cradle to the cradle.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems and drawbacks of the prior art, and it is an object of the present invention to provide a fixing module for fixing a mold, even if some defective shape occurs in the application form of shotcrete, It has its purpose.

It is another object of the present invention to increase the work efficiency while reducing the time required for the mold building work while stabilizing the fixation state of the fixture module and the mold.

It is another object of the present invention to enable a stable mold construction as a simple structure.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.
