DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block used for constructing a structure for stabilizing a retaining wall or embankment of a park, a bank of a river, a slope of a road, etc. An environmentally-friendly civil engineering structure that provides a space that can grow on the ground and a block that provides a space where fish can live in a safe environment, as well as ensuring structural safety as well as natural ecological safety. The present invention relates to an ecological stabilization block that can realize the above.

[0002]

2. Description of the Related Art Recently, re-evaluation of the natural environment, especially re-examination of natural scenery and urban scenery, has emerged as an important problem. Until now, in most cases, construction of retaining walls or embankments such as parks, lake shores of rivers, slopes of roads, etc. has given priority to soil stability and protection of slopes. Construction with concrete blocks has become mainstream.

[0003]

The slope of such a concrete structure provides a hard appearance that does not match the surrounding natural environment and gives a tasteless and dry feeling.

[0004] Along with this, recently, construction using a molding block having a molding beauty is increasing. However, since such shaped blocks are also made of concrete, plants cannot survive, so they can not leave the hard feeling of concrete as usual and are different from the original natural ecosystem around rivers or roads Therefore, it is a factor of deteriorating the natural ecological environment of plants or microorganisms, fish, small animals, and the like.

[0005] Also, since concrete blocks themselves do not have a drainage function, they are stuffed with gravel or the like, but the drainage is not carried out smoothly, and there is always a risk of collapse due to water pressure. It was difficult to secure.

[0006] On the other hand, in part of stabilizing a slope by using a block, a block is constructed while omitting an intermediate portion of the slope in some places, and a plant is guided to settle on the omitted portion. Attempts are being made.

[0007] However, since this method may cause a problem in stability of the slope due to the omitted part, the applicable range is extremely limited, and the distance from the vegetation on the entire slope is long. Therefore, such a method cannot provide a sufficient function for stabilizing a natural ecosystem.

[0008] As another method, there is a case where a retaining wall is installed by pouring a porous concrete material on site, and as the corner of the retaining wall becomes higher, an environment where plants are more difficult to settle is formed, and civil engineering is performed. Because the thickness of the cast must be increased for safety, it is more difficult for the plants to settle.

SUMMARY OF THE INVENTION Accordingly, the present invention is to solve the various problems of the prior art in constructing a structure for stabilizing a retaining wall or embankment such as a park, a lake shore of a river, a slope of a road, and the like. It is an object of the present invention to provide an eco-stabilizing block for realizing an environment-friendly civil engineering structure by creating an environment in which plants can be established and grow.

[0010] Another object of the present invention is to provide an ecological stabilizing block for securing a natural ecological environment by providing a space that is installed on the shore of the reservoir to allow fish to swim and settle in and out. Is to do.

[0011]

The ecological stabilizing block of the present invention for achieving the above object is a porous concrete product having a compressive strength of 150 kgf / cm ² or more while maintaining a porosity of 10% or more. In the central part of the body part, a cramming part penetrating up and down is formed, and a large number of vertical holes arranged in tandem in the left and right meat parts of the body part are formed, and are stacked so as to be shifted vertically. A technical feature is that a part of the front side of the earth and sand stuffing part is sometimes exposed to the outside to form a place where plants can be established.

According to another aspect of the present invention, there is provided a porous concrete product having a compressive strength of 150 kgf / cm ² or more while maintaining a porosity of 10% or more. The upper and lower surfaces and the front surface are opened at the middle part, and the left, right and rear sides are closed to form a fish space, and a number of vertical holes are formed in the body part on the left and right sides in tandem. A fundamental feature in the technical structure is that the space is built up on the lake shore of the reservoir to secure a space where fish can swim and settle in while entering and leaving the fish shoaling space.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 and 2 show a landscape block used to construct a structure for stabilizing a retaining wall or embankment of a park, a shore of a river, a slope of a road, or the like according to an embodiment of the present invention. 10 is shown.

The landscape block 10 has a body portion 11 having a thickness of a certain height while forming a hexagonal outer shape on a plane as a whole.

Such a body 11 has a size of 5 to 19 mm.
It is manufactured by mixing crushed stone, high-strength cement (or goros slag cement or potland cement), water, an admixture, etc., having a compressive strength of 150 kgf while maintaining a porosity of 10% or more. / Cm ² or more.

Here, the weight ratio between the high-strength cement and the crushed stone is set at a ratio of about 1: 4, 1: 5 (in the case of Goros slag cement or Potland cement, the ratio is 1: 3, 1: 4). The ratio of cement and cement is 25% or less, and the admixture uses a high-strength AE water reducing agent, and a small amount of a mixture of an adhesive and a fluidizing agent is added.

At the center of the body portion, there is formed an earth and sand stuffing portion 12 which penetrates up and down. A large number of vertical holes 13 are formed.

Further, a closing plate 14 for closing a predetermined portion of the lower surface of the front part of the earth and sand stuffing part 12 is integrally formed on the upper surface of the body part 11 so that the closing plate 14 is laminated while maintaining the vertical of 90 °. The earth and sand packed in the earth and sand stuffing section 12 is prevented from flowing away.

The blocks designed to be used for stabilizing the slope as described above are stacked so as to be shifted up and down in accordance with the degree of inclination of the slope, and at the same time, the slope is structurally stabilized. An environment-friendly civil engineering structure can be realized by providing a place where a part of the front side of the earth and sand stuffing unit 12 is exposed to the outside to allow plants to settle.

FIGS. 9 and 10 show a fishing block 20 according to another embodiment of the present invention, which is built on the shore of a lake or river to provide a place where fish can live.

In the middle of the body portion 21 of this fish block, there is formed a fish space portion 22 in which the upper and lower surfaces and the front surface are opened and the left, right and rear sides are closed. .

The fish block 20 is manufactured in the same manner as the landscape block 10 described above, and is a porous concrete product having a compressive strength of 150 kgf / cm ² or more while maintaining a porosity of 10% or more. The plane shape of 21 is also substantially hexagonal.

Blocks designed to provide a place for fish to swim as described above are stacked up and down on the shore of the reservoir to structurally stabilize the shore structure,
A space for fish to play and swim while entering and leaving the fish shoal space 22 is provided.

Hereinafter, a construction example of constructing a structure using the landscape block 10 and the fish block 20 according to the embodiment of the present invention will be described.

FIGS. 3, 4 and 5 show examples in which a retaining wall having a 90 ° vertical inclination is constructed using the landscape block 10 of the present invention.

In this construction example, after the foundation is completed, the upper structure is built. A fixed part of the landscape block 10 according to the present invention is fixed on the base part, and in constructing the upper structure, the landscape block 10 is vertically stacked on the landscape block 10 buried in the base part.

At this time, the blocks located in the upper and lower layers are stacked so as to intersect with each other, and are stacked so that the vertical holes 13 of the blocks located in the upper and lower layers are located on the same vertical line. Then, a fixing pin (metal rod), which has been subjected to antioxidation treatment, is inserted into the vertical hole so that the holes are connected to one another.

Earth and sand are densely packed in the earth and sand filling portion 12 of the block, and the nonwoven fabric 4 is applied to the rear surface of the block so as to be closely adhered to the earth. This nonwoven fabric is for preventing earth and sand from flowing into the pores of the landscape building block and clogging. While stacking the blocks, backfill the earth and sand on the back side and work while compacting with a compacting machine. A grid 1 is laid after the rear surface is compacted to make it flat with the block surface, and a block is further placed thereon to compact the soil so that the rear surface and the block are integrated. The grid 1 is installed at different intervals according to the slope, height, and characteristics of the earth and sand.

The 90 ° retaining wall thus constructed exposes a part of the front portion of the earth and sand stuffing portion 12 to the outside, and provides a place where plants can grow and grow on the exposed portion. Greening of the whole thing becomes possible.

Further, since the landscape building block 10 according to the present invention is made of a porous material and has good water permeability, it is possible to omit a separate work for filling the gravel for drainage. Not only is it good, but also because the soil packed inside the block continues to contain moisture, the plant growth environment is maintained in an optimal state.

Also, the 90 ° retaining wall secures a strong structural force by connecting the entire structure to one. That is, the earth and sand packed in the earth and sand stuffing unit 12 is continuously connected to the upper and lower layers, the fixing pin 2 connects these blocks as a whole, and the grid 1 connects to the rear layer of the structure. Since the whole and the rear soil layer are integrated, structural stability is ensured.

FIGS. 7A and 7B show construction examples in which a slope structure having a slope of 60 ° is constructed using the landscape block 10 of the present invention.

The construction of this construction example is generally almost the same as the construction of the above-mentioned 90 ° retaining wall. However, in this construction example, the rear vertical hole 13c of the landscape block located in the lower layer, the central vertical hole 13b of the block located in the middle layer, and the front vertical hole 13a of the block located in the upper layer are located one hole at a time on the rear side. The difference is that the blocks are staggered, so that the blocks 3 are connected as one unit using the fixing pins 2.

The slope structure having a slope of 60 ° according to the construction example has an advantage that a larger plant growing space can be secured than a structure having a 90 ° retaining wall.

FIGS. 8A and 8B show construction examples in which a slope structure having a 45 ° inclination is constructed using the landscape block 10 of the present invention.

This construction example is generally almost the same as the construction of the above-described 90 ° and 60 ° slope structure. However, in this construction example, two holes are shifted rearward so that the rear vertical hole 13c of the lower landscape block 10 and the front vertical hole 13a of the upper landscape block 10 coincide with each other. Are different.

In this structure, there is no problem in safety even if the grid 1 is omitted depending on the state of the slope and the upper and lower layers are connected only by the fixing pins 2.

The slope structure having a slope of 45 ° according to the construction example has an advantage that a larger plant growing space can be secured as compared with the slope structures having a slope of 90 ° and 60 °.

FIGS. 11A and 11B show construction examples in which the fish shore block 20 and the landscape block 10 of the present invention are used to construct a vertical shore structure of a reservoir.

According to this construction example, the lower part is constructed using the landscape block 10 and the upper part is constructed using the fish block 20. The area where the fish block 20 is installed is generally an area where the water surface is always maintained, and the water depth is maintained at a certain depth or more. Since it is generally difficult for aquatic plants to settle in such an area, the landscape block 10
It is preferable to secure the space where the aquatic plants can be established and the depth of the water by constructing the fish block, and then install the fish block 20 to secure the activity space for fish and the like. When constructed in this way, the entrance of the fish block 20 is covered by plants, and the plants take in oxygen into the water to provide food sources such as fish, thereby providing a more ecologically rich environment.

In the same manner as in the above-mentioned construction example, such a lake shore is constructed so that the upper and lower layers intersect, and the fixing pins 2, the grid 1 and the nonwoven fabric 4 are used, and the construction is almost the same. Detailed description is omitted.

On the other hand, the present invention is capable of constructing a structure which is modified into various structural forms other than the above-mentioned construction examples. Since it can be easily implemented by a person having the above, the description is omitted.

[0044]

According to the ecological stabilizing block of the present invention manufactured and built as described above, the entire structure can be integrated and built, so that only structural safety is ensured. In addition, it provides a space for plant growth and space for laying and avoiding fish, so that a natural ecological environment can be stably created and an environment-friendly civil structure can be realized. Because it can be easily done,
This is a very useful invention.
