Abstract

PURPOSE:To make the construction of slope easier as well as raise appearance of a banking structure by a method in which anchors are set between slope holders stacked up on a sloped ground and the central side of a banking, and a banking material is placed on the anchors and compacted repeatedly. CONSTITUTION:A trough-shaped slope holder 1 made of a perforated plate, having an U-shaped cross section, is stacked up on the slope of a banking and a filler 2 such as soil is charged from the upper opening. An anchor 3 is horizontally placed by winding the holder 1 into one end side and by positioning the other end side on the central side of the banking. A banking material 4 such as soil is placed on the anchor 3 and compacted flatly to the same level as the holder 1, and the same operations are repeated to construct a multi-layered banking of a given level.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to an embankment construction method in a limited area, and it relates to an embankment structure that has a stable structure even if the slope slope is steep, and is also aesthetically superior. be.

0002

BACKGROUND OF THE INVENTION One of the conventional embankment construction methods uses geotextile. This is shown in Figure 3.
In this method, geotextile a is laid, embankment b is poured on top of it, and then it is compacted, and this is repeated in multiple layers to construct an embankment body. In this case, the slope side of the embankment body has the embankment b wrapped around it by the geotextile a. Therefore, the geotextile a within the embankment b acts as an anchor, and the winding portion c can hold down the slope in a stable state.

0003

[Problem to be solved by the invention] The above-mentioned prior art includes:
The following problems exist. That is, on the slope side of the embankment body, since the embankment b is directly rolled up by the geotextile a, the shape of the rolled-up portion c is not constant, and the resulting slope shape becomes unsightly. As a way to solve this problem, after putting soil in a bag and making a sandbag,
There is a method of wrapping this sandbag with geotextile a, but in this case, the work of filling the bag with soil and making the sandbag is very time-consuming.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems, and provides an embankment structure that provides an excellent appearance of the slope and also allows easy fabrication of the slope. The purpose is to provide. That is, the present invention provides a gutter-shaped slope retaining material formed of perforated plates having a substantially U-shaped cross section and stacked on the slope of an embankment, the slope retaining material being wrapped around one end, and the slope retaining material being wrapped around the other end. A planar anchor body placed in the center of the embankment body and laid horizontally, an infill material placed inside the slope support material, and an embankment material placed on the planar anchor body. It is an embankment structure. In addition, a gutter-shaped slope retaining material formed with a perforated plate having a substantially U-shaped cross section is stacked on the slope of the embankment, one end is fixed to the slope retaining material, and the other end is pulled out. A linear or band-shaped anchor body with a resistor attached and located at the center of the embankment body and laid horizontally, an infill material inserted into the inside of the slope support material, and an anchor body placed on the planar anchor body. It is an embankment structure made up of the input embankment materials.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. <A> Slope holding material As shown in FIG. 1, the slope holding material 1 is a gutter-shaped frame member formed of a perforated plate and having a substantially U-shaped cross section. The perforated plate used has a certain degree of rigidity and can maintain a constant shape. For example, expanded metal, wire mesh, etc. can be used. This slope retaining material 1 is piled up at a predetermined inclination angle on the slope part of the embankment. In this case, since the slope retaining material 1 can maintain a constant shape, the work of stacking it on the slope can be easily performed.

<B> Filling material Inside the slope retaining material 1, a filling material 2 such as soil is put. When inserting the filling material 2, it can be easily done by simply inserting it from the upper opening of the slope retaining material 1.

<C> Planar Anchor Body The planar anchor body 3 is a net material with high tensile strength, such as geotextile. This planar anchor body 3 is laid in the horizontal direction with the slope retaining material 1 wrapped around one end and the other end positioned at the center of the embankment body. If necessary, drain water using a water-permeable sheet material.

<D> Embankment material Earth or the like is used as the embankment material 4, which is poured onto the laid planar anchor body 3 and flattened by rolling to approximately the same height as the slope support material 1. The above operations are repeated until a predetermined height is reached to construct a multi-layered embankment. The completed embankment body has a stable embankment structure because the slope support material 1 is held down by the pull-out resistance of the planar anchor body 3. In addition, since the shape of the slope retaining materials 1 stacked on the slope portion is constant, the aesthetic appearance of the slope surface is excellent.

<E> Band-like anchor body In addition to the above-described planar anchor body 3, a band-like anchor body 5 as shown in FIG. 2 can also be used. For the band wire anchor body 5, reinforcing bars, band cloth, band iron, etc. can be used. Then, one end side of this band wire-shaped anchor body 5 is fixed to the slope support material 1 with a bearing pressure plate 51 etc., and a pull-out resistor body 52 such as a plate is attached to the other end side, and the center of the embankment body is Position it on the side and lay it horizontally. When such a band-like anchor body 5 is used, the slope support material 1 can be piled up in a state close to a straight wall.

0010

[Effects of the Present Invention] Since the present invention is as explained above, the following effects can be obtained. <A> Since the slope retaining material has a certain degree of rigidity, the shape of the slope retaining material piled up on the slope part is constant, and the aesthetic appearance of the slope of the embankment body is excellent. <B> When inserting the filling material into the slope retaining material, it is sufficient to simply insert the filling material through the upper opening of the slope retaining material installed on the slope section. Therefore, compared to the production of conventional sandbags, it is easier to produce the slope part. <C> Since the slope support material can maintain a constant shape, it is easy to stack it on the slope. <D> By holding down the slope retaining material with the band wire-shaped anchor body provided with the pull-out resistor, the slope retaining material can be stacked in a state close to a straight wall.
