Description

Surface protection structure using natural stone and its construction method {STRUCTURE FOR SLOPE PROTECTION USING STONE AND CONSTRUCTION METHOD THEREOF}

The present invention relates to a surface protection structure and its construction method. In particular, the surface protection structure using natural stone and the construction method using a plurality of inclined wall protection hole structure, support members, connecting hardware, natural stone and the space between them is cemented or backfilled with aggregate at the same time. It is about.

In general, the cut surface, inclined wall, slope, etc. formed in the housing complex or roadside, etc., if left untreated, may cause great damage due to collapse by rain or earthquake. As a way to prevent this, protective structures such as retaining walls are being constructed. Such a retaining wall structure is conventionally made by stacking cement blocks or placing concrete.

However, in recent years, with increasing interest in residential aesthetics and the environment, an environmentally friendly form is required for the retaining wall structure, and in response to this trend, one of the alternatives to the uniform and dry concrete retaining wall is a mountain wall structure. .

The mountain wall is an integrated natural stone structure made for landscape or structural purposes, and refers to an environmentally friendly natural site restoration type construction method that can simultaneously perform the function of the retaining wall and the landscape. Compared with the existing retaining walls, the mountain wall method can produce an environment-friendly and natural appearance by stacking natural stones, and can be constructed in a short air with a relatively simple process in the construction surface, and is flexible in displacement. There is an advantage to deal with.

However, such a mountain wall method has a problem that the structure is very vulnerable because each natural stone behaves separately because of the accumulation of a plurality of natural stones. Accordingly, in the case of the conventional mountain wall structure, when the construction height is increased, the influence of the earth pressure is increased, and it is difficult to design it over a predetermined height in structural analysis. Furthermore, when a natural disaster such as an earthquake or flood occurs, it collapses with the back soil. There is a risk that can lead to large accidents.

Various methods and technical attempts have been made to solve the problems of the mountain climbing method.

Figure 1a shows a law-law structure 10 according to the prior art for solving the above problems.

The law structure according to the prior art, the support post 12 is connected to the inclined wall 20 through the fixing bar 11, the connecting hardware 13 connected to the support post 12, and the connecting hardware 13 ) Is composed of a plurality of natural stones (14) fixed. The space between the inclined wall 20 and the natural stone 14 and the ground 21 is backfilled and compacted with soil 19 such as soil.

For structural stability, many natural stones 14 are usually placed vertically and horizontally. That is, when the first stage natural stone 15 is disposed vertically, the soil 19 is filled in the space between the inclined walls 20, and the next natural stone 16 is horizontally disposed. Thereafter, two stages of natural stones 17 are vertically disposed, and the natural stones 18 are horizontally disposed after the soil 19 is filled up to its height. In this way, a plurality of natural stones 14 are multistage.

In the case of the vertically placed natural stone (15, 17) is a general height is about 3m, the horizontally placed natural stone (16, 18) is a general width of about 1m.

1b shows another legal structure according to the prior art. It consists of a sloped wall protection hole structure, such as rock bolt 31, natural stone 34, and connecting hardware 33 connecting them, the space therebetween is backfilled with soil 39, such as soil and compacted do.

The conventional surface protection structures made in this way have several problems.

The surface protection structures shown in FIGS. 1A and 1B have to backfill the interspace with soil, such as soil, but are difficult to compact.

When constructing the surface protection structure, arrange the first stage natural stones (15, 35), connect them through the connecting hardware, and then backfill the soil, and then compact the ground with natural stones (16) or two stage natural stones arranged horizontally. Arrange the (17, 36) and connect it again through the connecting hardware, and then backfilling the soil, pledging, and again to place the three-stage natural stone (37), sequential construction is required. This compaction construction is generally made every 30 cm.

However, it is difficult to construct a suitable compaction by complicatedly arranged connecting hardware. Moreover, in the case of using natural stone, it is difficult to compact the construction because the connection hardware is inevitably placed due to the natural stone of the different size. In fact, it is very difficult to achieve a degree of consolidation of more than 80% in most of the mountain wall constructions performed at the construction site.

Even with water compaction, it is not desirable to consider the characteristics of most incisions where construction time is very delayed and water supply is difficult. In this case, if the proper compaction is not made, settlement occurs continuously, and it is easy to cause construction delay due to the necessity of subsequent construction such as ridge construction.

Moreover, when settlement occurs continuously, the surface structure itself may collapse sequentially, as shown by the dotted lines in FIG. 1B. That is, as the soil is settled, the lowest natural stone may slump, break or the anchor may deviate.

In addition, in the case of blasting stones mainly used for mountain walls, the thickness of the blasted stone is very thin compared to the stone area, so that the stone is broken by the earth pressure or the mountain wall itself.

In addition, surface protection structures in this manner are difficult to install on slopes higher than 14 m by structural analysis. In recent constructions in which numerous apartments or roads are dredged in mountains, sloped walls, etc., this type of surface protection structure is undesirable.

In addition, when using a natural stone arranged horizontally, as shown in Figure 1a, there is a disadvantage that a large amount of horizontal space is occupied the surface protection structure occupies a lot of space. For example, the surface protection structure installed on the slope of 9m should have a space of 3m natural stone space and soil filled in the horizontal direction, so the surface protection structure needs a width of about 5-8m.

On the contrary, since the natural stone disposed horizontally as shown in FIG. 1B is not used, a high earth pressure applied to the natural stone is difficult to obtain a stable structure. Moreover, since the construction of directly welding the connecting hardware 33 to the lock bolt 31 is difficult, the connecting hardware does not receive sufficient tensile strength.

The present invention, as described above, to provide a legal structure that can be constructed up to a higher height without losing stability in structural analysis.

In addition, it is to provide a space-saving legal structure by reducing the width compared to the prior art.

In addition, it is an object of the present invention to provide a legal structure that obtains superior structural stability compared to the prior art.
