Description

Civil nonwoven soil brick and construction method using the same

The present invention relates to a non-woven soil brick for civil engineering, in particular in the civil works, such as the construction of dikes and embankments in rivers or lakes can be used as a substitute for conventional concrete or cement blocks to allow the water to pass through, but the soil is not moved The present invention relates to a nonwoven soil brick that enables vegetation, and a method of constructing a structure such as an embankment using the soil brick.

Conventionally, in order to prevent such soil loss due to the loss of soil due to rainwater on the banks of the river banks and to cause the flooding, and the appearance of cleanliness, it is shown schematically in FIG. As has been the use of concrete or cement blocks 1 has become common. However, when a block made of concrete or cement is used in a levee or the like, the loss of soil is prevented, but when water is not passed through the water and the water is blocked, the water is blocked. In addition to the earth pressure, the water pressure gradually increases and eventually collapses, and the use of these blocks in the construction of river embankments can also cause rapid flooding and cause flooding downstream. Got to know.

In addition, in the past, natural rivers provided a habitat for fish and other aquatic organisms along with a natural purification function to purify water quality contaminated with wastewater that flows into the river by growing various plants around the river. It had a function to reduce the loss of soil, but since no plant can grow on the embankment of cement or concrete block, it can not be expected to purify by the plants around the river and to inhabit the fish and aquatic life. Rather, it was suggested that it could only act as a drainage of waste water, which could endanger human survival. As a result, we are not only focusing on research efforts to build natural-friendly dikes where plants can grow by constructing stones and soils without using cement or concrete blocks when constructing new dikes such as rivers. In addition, cement and concrete blocks that have been installed on existing banks are also removed to create a natural environment.

The present invention is to solve the problems caused by the construction of the structure, such as the embankment by the conventional cement or concrete block, a ground structure that prevents the ground collapse of the river banks, for example, by preventing the movement of the earth and sand through the water. The purpose of the present invention is to provide a nonwoven soil brick made of soil to prevent the loss of soil by using a nonwoven fabric, to be permeable, and to allow plant roots to grow.

Another object of the present invention is to provide a method for constructing a structure such as a dyke to create a natural environment using the nonwoven soil brick.

12 nonwoven fabric

Civil engineering non-woven soil brick of the present invention for achieving the above object is formed by pressing the soil in a predetermined form to form a soil brick, sewing to surround the entire outer surface of the soil brick cured with a permeable nonwoven fabric. When forming the soil brick, the material of the soil may be a viscous material such as sludge, or may be used to add clay as a caking additive to the general soil. In addition, the nonwoven soil brick is preferably formed of a polygon.

In addition, in the construction method using the nonwoven soil brick according to the present invention, the nonwoven soil brick coated with the nonwoven fabric on the soil brick, for example, is laminated and arranged at least one or more layers in the ground of the bank inclined walls, and arranged adjacently Nonwoven fabrics of mud bricks are constructed by sewing them together by known means such as hand sewing. When the nonwoven soil bricks are laminated, the clay soils are made low in viscosity between two adjacent nonwoven soil bricks to be used for mortar so that the nonwoven bricks do not slip by earth pressure or water pressure.

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

2 is a perspective view of a portion of the nonwoven soil brick 10 according to the present invention in a cross-sectional view made of a non-woven fabric 12 is sealed on its outer surface so as to surround the soil brick 11 as a whole. Preferably, the nonwoven material is polyester or polypropylene. The nonwoven soil brick 10 of the present invention is first made by putting the soil into a mold of a predetermined shape to press-mold to shape the soil brick 11, and then sewing with a nonwoven fabric to cover the outer surfaces thereof. As the material of the soil brick 11, general earth sand, clay sand and sludge having more clay components may be used, and as the clay component increases, the moldability and shape retention characteristics of the soil brick become better. Since the permeability of the brick is degraded, an appropriate one should be selected according to the surrounding environment in which the brick is used.

For example, where there is a rapid increase in pore water in rainy weather, and a large hydraulic pressure is applied, it is required to reduce the risk of collapse by using a relatively large permeable soil soil brick to drain the leachate well. It is preferable to use clay bricks containing a relatively large amount of clay to increase shape retention characteristics and cohesiveness in areas where the surface is in contact with water or water pressure is large, such as banks.

In addition, the soil brick 11 is a polygon of another shape other than the cube shown in FIG. 2, that is, like the soil bricks 13, 14, and 15 illustrated in FIG. 3, FIG. 4, and FIG. It can be molded in various forms to have shapes that mesh with each other. The polygonal nonwoven bricks have the effect of increasing the bearing capacity for preventing the collapse of the nonwoven bricks, which are constructed against the hydraulic pressure acting laterally by the flow of the river to the outer peripheral portions are interlocked with each other.

The soil brick 11 of the shape shown in FIGS. 2 to 5 thus made is inserted into a nonwoven fabric bag 16 made by sewing in a shape corresponding thereto, and the opening is sewn and sealed by hand sewing, for example. By completing the non-woven brick, the non-woven fabric is put into the mold at the time of forming the clay brick may be molded by putting the soil therein, and then sewn and sealed. In the drawing, reference numeral 17 denotes a seam.

Using the nonwoven soil brick 10 of the present invention made as described above, for example, when explaining a method for constructing a structure such as a dike, as shown in Figure 6 nonwoven soil brick 10 on the slope of the river Are arranged to be interlocked with each other and alternately arranged on top of each other, and the nonwoven fabrics of the nonwoven soil bricks adjacent to the top, bottom, left, and right sides are combined by sewing and integrated as a whole to integrate friction forces acting on the surface of the nonwoven bricks by the flow of the river. It is supported to prevent the loss of the soil brick of each nonwoven fabric.

In addition, when the nonwoven soil bricks are laminated, clay soils are applied between the upper surface of the nonwoven soil bricks of the lower layer and the bottom surface of the nonwoven soil bricks of the upper layer to lower the viscosity and apply them together with cement mortar to slip the nonwoven soil bricks by soil pressure and water pressure. It is preferable to prevent the collapse of the nonwoven soil brick of the present invention to be installed on the inclined wall or the bottom surface of the river by increasing the bearing force.

For example, when constructing a river bank with the nonwoven soil brick according to the present invention, the durability and rigidity of the nonwoven soil brick itself is weaker than that made of concrete or cement, so that the nonwoven fabric is damaged over time and the shape of the soil brick itself. Although it can be changed, the nonwoven bricks allow the drainage of the water that penetrates them, while the movement of the soil is prevented by the nonwovens, and the bricks themselves are suitable for vegetation, so that the plants can be rooted and grown in the bricks in the nonwoven fabric. As the natural greening of the inclined wall made of nonwoven soil bricks is made easily and quickly, the ground is strengthened to prevent the loss of the inclined wall surface due to running water, thereby achieving a strong natural embankment.

In particular, by covering the soil such as clay soil or humus soil of the tidal flat on the surface of the part of the construction of the soil brick of the present invention, the planting of the plant is made faster, and moreover, such a clay is introduced into the nonwoven fabric and thus, By integrating with the soil, slopes such as embankments constructed with nonwoven soil bricks can be more firmly and quickly stabilized.

The case where the nonwoven soil brick of the present invention is applied to the inclined surface of the river bank is described as an example, but not only the inclined surface but also the soil brick can be installed on the bottom surface as shown in the drawing, and other materials such as a seawall, a raft, a playground, a waterway or It can be easily understood that the same method can be applied to civil engineering fields such as farm roads, road slopes, railway ground stabilization and urban forging.

In the nonwoven soil brick according to the present invention, water is passed through the nonwoven fabric, but when the soil is prevented from moving, the soil is leaked due to the movement of the surface water or the penetration of the underground vein. The conventional problems that occur are solved, the plant is made of soil that can easily grow and grow, the natural greening is made relatively fast and can be used as a natural-friendly civil engineering material to achieve a rapid ground stabilization.
