Abstract

PURPOSE: An upright retaining wall is provided to simplify construction and to reduce construction expenses such as the cost of materials and labor costs, etc. CONSTITUTION: The upright retaining wall comprises the steps of heading up reinforced earth(7) composed of sand and stone or broken stones on an inclined wall(6), installing grids(10) horizontally to make a retentive plate(8) buried under the reinforced earth(7), installing an outer concrete wall(3) containing broken stones on the outside of the reinforced earth, building stone mound composed of native rocks(1) or concrete blocks on the outer concrete wall(3) to cross each other, perforating a steel bar fitting hole(9) on a contact plane of the stone mound, and interposing a steel bar(2) coupled perpendicularly to the outer end of a grid(10) supported by a retentive plate(8) buried under the reinforced earth(7) to the fitting hole(9).

Description

Retaining wall constructed erectly

The present invention relates to a retaining wall that is piled upright as a natural stone or a concrete block filled with a solid inside on an inclined wall surface (mountain wall), and a natural block or concrete block (hereinafter called red stone) filled with a natural stone is vertically inserted therein. An upright construction retaining wall that is constructed upright while being supported by a steel bar and a grid.

Generally, when constructing retaining wall with natural stone or concrete block together with reinforcement soil on mountain wall (sloped wall surface), the retaining wall is gradually inclined toward the inclined surface from the bottom to the top to prevent the retaining wall from collapsing by water pressure or earth pressure. In the case of high and retaining walls, natural stone and natural stone or concrete blocks (red stone) had to be fixed by fixing with grout, mortar or synthetic adhesive.

Such retaining wall stacks have to be stacked inclinedly with red stones, so that the ground is narrowed on the retaining walls, and because the retaining walls must be fixed with fixing agents between the red stones, material costs, labor costs, and construction time are high.

Also, unlike the above, the rod is inserted into a certain part of the upper part or the side of the red stone, and the upper bar is stacked while the red bar is placed, and the rod is inserted into the side bar and the grid is connected thereto. Applicant has filed a patent application No. 10-2002-0025446 to support the retaining wall without being collapsed by the grid while being buried. In this case, however, the steel bar must be inserted in several places on the upper and lower sides of the red stone (natural stone). Even though the steel rod is inserted, the steel rod connected to the grid is inserted and supported horizontally in the natural stone, so it is inconvenient to fix it by sticking glue or wedge into the steel rod insertion hole. There were difficult defects and also eliminated the above conventional defects. Applicant is an example of forming an upright retaining wall by stacking red stones upright while fixing the retaining wall in an upright position and fixing it with a fixing agent such as mortar, grout material, or synthetic resin adhesive between the red and red stones to widen the surface of the retaining wall formed by the retaining wall as much as possible. This application has been filed as a patent application No. 10-2003-0025625, but this method is difficult to construct because it must be fixed between the red stone and the red stone as a fixing agent, which requires a lot of work time and expensive raw materials, etc. Not only were they defects, but there were also defects that could lead to red sedimentation depending on the concentration of the binder and the adhesive strength.

The present invention solves the drawbacks of conventional inclined retaining wall or upright retaining wall stacking as described above, and provides an upright building retaining wall that can be constructed with low material cost and simple construction and structure. It will be described in detail as follows.

10: grid

Stacking the reinforcement soil 7 made of soil or rubble on the inclined wall surface (mountain wall) 6, the grid 10 is installed horizontally so that the support plate 8 at the inner end is embedded in the reinforcement soil at a predetermined height, and the rubble is outside the reinforcement soil. In an upright construction retaining wall in which a concrete outer wall (3) containing uprights is installed upright, and then an upstanding retaining wall is constructed on the upright concrete outer wall, wherein the concrete outer wall (3) is a natural stone (1) or a solid concrete block (1 '). Grids (10) of which the upper and lower piles are stacked alternately, and a steel rod inserting hole (9) is installed in a portion where the upper and lower sides of the red stone are alternately contacted with each other, and the support plate (8) of the inner end is embedded and supported by the reinforcement soil (7). It is an upright construction retaining wall formed by constructing an upright retaining wall while inserting a steel bar 2 that is installed to be orthogonal to the outer end of the c) in the insertion hole 9.

The steel bar is selected from metal rods such as fiber glass or stainless steel.

The upright retaining wall constructed as described above has a steel plate (2) installed orthogonally coupled to the grid (10) that is being used, while being firmly inserted and fixed in the insertion hole (9) of the upper and lower stacks of staples stacked up and down. 8) is embedded in the reinforcement soil (7) to support the red stones firmly, so that the bearing capacity is excellent, even if the retaining wall is built upright to remain firmly without falling or pushed.

The erect retaining wall constructed by the present invention as described above does not require any additional materials or construction except steel rods, so that the material can be saved as well as the construction is simple, so that mass production can be performed in a short time. do.

In the upright construction retaining wall constructed by the present invention, the support plate 8 of the inner end is fixed to the outer end of the grid 10 buried in the reinforcement soil at the top and bottom of the natural stone or concrete block, and thus the other supporting structure is fixed. However, despite the upright construction without the use of fixing agents, it has the effect of having strong bearing capacity.
