Abstract
Description
The present invention relates to a construction method of a reversing vertical cut slope reinforcing retaining wall, and more particularly, in installing the retaining wall on the front surface of a vertically cut slope, after cutting the slope downward with a cutting plan and moving upwards from below. Unlike the conventional method of installing the retaining wall by sequentially constructing the cutouts at the top of the slope, the excavation is performed by digging down the slope downward, and the wall of the retaining wall is sequentially constructed, thereby quickly retaining the retaining wall for the reinforcement of the vertical cutout slope. It relates to a construction method of a retaining wall of a new structure that can be constructed economically and economically.
Due to the nature of Korea, which has a lot of mountainous terrain, many slopes are cut off during the construction of roads, railways, industrial complexes and residential lands, and retaining walls are often installed at the bottom of the cut slopes. However, as land prices increase and civil complaints increase due to environmental damage, it is increasingly necessary to construct retaining walls by vertically cutting slopes when installing such retaining walls.
As a method of constructing such a cut slope retaining wall, conventionally, a method of installing the retaining wall sequentially from the bottom after cutting the slope inclinedly has been used. However, when the slant is cut in such a manner, the amount of cut soil and the backfill after the retaining wall construction increase, resulting in an increase in the amount of earthwork, which causes the cost of construction and an increase in the construction period. In addition, problems such as collapse of the slope may occur at the time of cutting, or at the stage before the retaining wall construction after cutting.
In particular, when there is a facility such as a building on the back of the retaining wall installation position, there is a limit that it is impossible to cut it inclined itself. In this case, it is necessary to cut vertically for the protection of the facility. To ensure safety when cutting, a separate provision for preventing the collapse of the vertical cutting surface is to be installed separately, and after the cutting is completed, the retaining wall must be constructed upward from the bottom. Therefore, the cost according to the installation of the cut-away collapsed temporary installation is increased, and since the retaining wall is constructed only from the bottom of the cut-out surface, the increase in construction period cannot be avoided.
In addition, in the case of the retaining wall installed on the front of the cut slope, a retaining wall having an aesthetic appearance that can be harmonized with the surrounding environment is required. In the conventional construction method, the retaining wall exterior is beautiful because the wall of the retaining wall is constructed using site-cast concrete. There is a limit that is difficult to achieve. It is also possible to use a method of attaching the stone to the front of the retaining wall, but in this case, it is very disadvantageous in terms of cost and time because the stone must be manually attached by hand, and in the case of the high retaining wall, a separate work scaffold and scaffolding must be installed. In addition to the increase, the risk of a safety accident is high.
The present invention was developed to solve the above problems, and in the construction of the retaining wall by cutting the slope vertically or almost vertically, unlike the conventional method of constructing the retaining wall from below after vertical cutting, vertical cutting is possible. It aims to be able to construct vertical cut slope reinforcement retaining wall safely, quickly and inexpensively without installing any temporary equipment to prevent the collapse of the slope at the stage before or after the cutting.
In addition, the present invention in the construction of the retaining wall by cutting the slope vertically or almost close to the vertical, by applying a factory-made panel of the retaining wall wall to give a pattern to the panel itself or to the front panel The object of the present invention is to attach decorative materials such as stones, tiles, etc. to have a beautiful appearance, and to efficiently construct a vertical cut slope reinforcing retaining wall having excellent aesthetic appearance.

In the retaining wall construction method of the present invention as described above, for the installation of the tensile reinforcement, when the ground vertically cut above the height that can be installed one panel to the front of the thumb pile, for the tension reinforcement to the rear of the thumb pile Drill holes; Inserting and placing the tensile reinforcing member into the hole for the tensile reinforcing material so as to be installed on the rear ground through the thumb pile, and injecting a grouting material into the hole for the tensile reinforcing material to fix one end of the tensile reinforcing material in the ground; Disposing the panel at intervals from the thumb pile to the front of the thumb pile, and fixing the other end of the tensile reinforcement to the front of the panel while the other end of the tensile reinforcement penetrates the panel; Placing a filler in the gap between the front of the thumb pile and the back of the panel; The wall of the retaining wall is constructed by repeating the above operation to the plan of the retaining wall wall, the front vertical ground cutting operation of the thumb pile, the tension reinforcing material installation work, the panel installation work, the fixing work of the tension reinforcement material, The wall of the retaining wall may be constructed by repeating the filling of the filling material to the plan of the retaining wall.
In this case, it is preferable that a recess is formed on the front surface of the panel so that the fixed end of the tensile reinforcement does not protrude outward so that the other end of the tensile reinforcement is located in the recess.
In addition, in the retaining wall construction method of the present invention, in order to install the tensile reinforcement member, when the ground is vertically cut to a height higher than the height at which one panel can be installed in front of the thumb pile, the hole for the tension reinforcement member is located behind the thumb pile. Perforating; The tensile reinforcing member is inserted into the tensile reinforcing material hole so as to be installed on the rear ground through the thumb pile, and the grouting material is injected into the hole for the tensile reinforcing material to fix one end of the tensile reinforcing material in the ground. Fixing the other end of the to the thumb pile; Disposing a panel at a distance from the thumb pile to the front of the thumb pile; Placing a filler in the gap between the front of the thumb pile and the back of the panel; The wall of the retaining wall may be constructed by repeating the front vertical ground cutting of the thumb pile, installing and fixing the tension reinforcement member, installing the panel, and placing the filler material up to the plan of the retaining wall wall. .
In addition, in the retaining wall construction method of the present invention, in order to install the tensile reinforcement member, when the ground is vertically cut to a height higher than the height at which one panel can be installed in front of the thumb pile, the hole for the tension reinforcement member is located behind the thumb pile. Perforating; The tensile reinforcing member is inserted into the tensile reinforcing material hole so as to be installed on the rear ground through the thumb pile, and the grouting material is injected into the hole for the tensile reinforcing material to fix one end of the tensile reinforcing material in the ground.
