Description

A green sheet for civil construction with tube

The present invention relates to a civil construction, and more particularly, to a green sheet for an economical and eco-friendly tube-type civil construction without applying a subsequent banking greenery while applying the tube method during the river or river embankment construction.

In general, a tube-based civil construction refers to a method of putting sand and water inside a tube-shaped fabric when installing an embankment of a river or a river, and then constructing gravel, crushed stone, cement, etc. on the outside of the tube. This is preferred because it is easy to construct and the strength of the dike is improved, and it is easy to cut and dispose of when it is not needed.

However, since the fabric used in the tube is not an environmentally friendly material, it is difficult to create a plant ecosystem, which damages the aesthetics and inhibits the growth of the plant.

For example, Korean Registered Patent No. 0774551 is constructed by filling filter material such as soil, sand, aggregate, and fine stone into the erosion-proof construction surface, but using drainage network and cover as a gist. The arc is characterized in that it is possible to freely adjust the injection amount of the air tube (7) to easily adjust the height of the dike and to easily and quickly treat the water of the dike during the ground improvement as well as after completion of the ground improvement. Therefore, the above-mentioned prior art has not been overcome.

Accordingly, the present invention is to fundamentally solve the conventional problems as described above, while applying a tube method during the river or river embankment construction does not require a subsequent dike greening process can be economical and environmentally friendly design The purpose is to provide a green sheet for the civil engineering method.

In order to achieve this object, the present invention is a sheet for civil engineering of the embankment in a tube method: by mixing 3 ~ 7wt% UV light stabilizer for inhibiting embrittlement based on synthetic fibers, elongation ratio 5.5-8: 1, thickness First yarn (inclined) produced from split yarns with 1,500 to 5,000 denier and fabric strength of 5 to 25 ton; And a second yarn (weft yarn) made of a twisted bundle-type tissue resistant to strength and water leakage mainly based on high-strength fibers and natural fibers; but the first yarn (tilt) is made of polypropylene (PP). , Polyethylene (PE), polyethylene terephthalate (PET), and any one selected from nylon, and the second yarn (weft) is used to mix any one or more selected from flax, hemp, hemp, jute, cotton It is characterized by.

On the other hand, the terms or words used in the present specification and claims are not to be construed as limiting the ordinary or dictionary meanings, the inventors should use the concept of the term in order to explain the invention in the best way. Based on the principle that it can be properly defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configuration shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all of the technical ideas of the present invention, and various alternatives may be substituted at the time of the present application. It should be understood that there may be equivalents and variations.

As described in the above configuration and operation, the green sheet according to the present invention does not require a subsequent banking greening process while applying the tube method during the river or river banking work, it is possible to achieve an economical and eco-friendly design to provide.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram showing an enlarged tubular green sheet according to the present invention, Figure 2 is a configuration diagram showing a state immediately after construction of the green sheet according to the present invention, Figure 3 is a configuration showing a greening state of the green sheet according to the present invention It is also.

The present invention relates to a sheet (aka green sheet) for civil construction of the embankment in a tube method, and is applied to geotubes that are utilized as harbor breakwater cores, erosion prevention structures of coastal wetlands, and the like. Geotubes are tubes made of permeable geotextiles, usually filled with sand or dredged soil and water.

According to the present invention, the first yarn (inclined, 10), which is made of a split type 15 yarn by mixing 3 to 7 wt% of UV light stabilizer for inhibiting embrittlement based on synthetic fibers, is used. It is preferable that the first yarn (inclined) 10 selects higher strength than conventionally required. The UV light stabilizer may be a benzophenone system and a benzotriazole system as a UV absorber that selectively absorbs ultraviolet rays and converts them into harmless thermal energy. Split-type 15 yarns have a net-like shape when they are unfolded to facilitate water drainage during work.

At this time, the first yarn (tilt, 10) is selected from among polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), nylon. The first yarn (tilt, 10) is produced with a draw ratio of 5.5 to 8: 1, a thickness of 1,500 to 5,000 denier, and a fabric strength of 5 to 25 ton. It is recommended that the draw ratio satisfy KS K0753 and the strength meet KS K0753 (International ISO10319), and the draw ratio and strength can be changed to some extent by adjusting the thickness (denier). The strength can be 25 ton for dikes, 20 tons for bridge reinforcement, 15 tons for farming, and 10 tons for dike protection.

In addition, according to the present invention, a second yarn (weft yarn, 20), which is made of a twisted bundle type 25 structure resistant to strength and water leakage, is used as the main material of high strength fibers and natural fibers. Natural fiber is like a rope bundle bundle (25) to be bundled, but the degree of twist is not so limited. The more twist of the twisted bundle type 25, the higher the strength and the more favorable for leaking, but should bear the productivity decrease.

At this time, the second yarn (weft, 20) is used by mixing selected from flax, hemp, hemp, jute, cotton. The second yarn (weft, 20) of the present invention prefers biodegradability to strength, but if the strength is high, the overall strength can be improved after weaving with the first yarn (tilt, 10). In this respect, jute, which has been used as a rope in the past, is preferable, but may be mixed with other natural fibers described above.

The present invention is subjected to the process of weaving the first yarn (tilt, 10) and the second yarn (weft, 20) to the fabric. In weaving, a variety of weaving methods such as plain weave, two-will, runner, mat, and Panama can be applied, and strength and productivity are important choices. Of course, the woven fabric must also meet the requirements of water permeability, UV blocking rate.

In the construction, when the levee is constructed by the geotube method using the fabric sheet woven from the first yarn (tilt, 10) and the second yarn (weft, 20), the second yarn of natural fiber after a certain period of time ( Since the weft, 20 is decomposed, the green vegetation 40 is naturally generated on the dike without any subsequent construction. Of course, by applying the greening soil 30 on the fabric sheet can reduce the time required for natural greening.

As described above, the green sheet of the present invention does not require a subsequent dike greening process while applying a tube method when constructing a river or river embankment, so that the green sheet may be economically and eco-friendly.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
