It is installed for applications such as a ridge, a waterway, an excellent drainage channel, a waterway, an agricultural waterway, and a small section so that rainwater or rainwater can be smoothly introduced and drained. These drainage channels are mainly used in concrete construction methods, concrete concrete pipes and PE prefabricated drainage ways, which are assembled by forming concrete gaps with concrete material. These methods, due to the durability and inconvenience of the construction, fail to perform the role of the drainage line, causing disasters and serious accidents.

The concrete pouring method has many stages of construction such as trenching, formwork installation, concrete pouring, curing, demolition, formwork installation, wall casting, curing, transportation, And the cost of the concrete is increased.

The drainage channel is a waterway installed for drainage. The drainage is largely used in the field, such as concrete installation method, concrete method, Since the concrete drainage system is suitable for small scale, it is difficult to control the quality in the field construction and the quality of the construction is poor, and the degree of deterioration of the quality and strength is serious and the watertightness is low. Of the steel is corroded.

In addition, the PE prefabricated drain can be easily manufactured and installed, and is economically advantageous over other types. However, since the self-weight is relatively light, buoyancy due to the water infiltrating the bottom of the bottom of the channel can cause water There is a problem that it can be destroyed by itself. Especially, when exposed to sunlight for a long time, there is a possibility of deformation due to deterioration due to ultraviolet rays, leakage occurs frequently due to deterioration in durability of the joint portion connecting the water channel, There is a problem that deformation is generated due to the surrounding side wall earth pressure and it is vulnerable to heat, so that deformation due to fire and loss of functionality of the water channel are caused.

The construction of the concrete water pipe is easy and the construction period does not take long. However, due to the weight of the concrete water pipe, the equipment is needed for transportation and installation, and there is a problem that a gap is generated after the assembly, And there is a need for equipments and manpower due to the dismantling and replacement of the water pipe during maintenance due to defects.

These methods have the problem that it is difficult to maintain the normal waterway cross section due to the frequent slope collapse or the introduction of the soil, during the rainy season, resulting in a demand for frequent maintenance.

1 is a perspective view of a multi-layer structure mat using geosynthetic fibers and polymer cement mortar according to an embodiment of the present invention.

First, referring to FIG. 1, a multi-layered mat using geotextile and polymer cement mortar according to the present invention will be described.

The multi-layer structure mat using the geosynthetic fiber and the polymer cement mortar according to the present invention,

A first geosynthetic fiber (10);

A first adhesive (20) applied to the first geoscientific fiber (10);

A waterproof mat (30) laminated on the first adhesive (20);

A second adhesive (40) applied to the waterproof mat (30);

A second geosynthetic fiber (50) laminated on the second adhesive (40);

A first polymeric cement mortar (60) applied over the second geoscientific fiber (50);

A third geoscientific fiber (70) laminated on the first polymer cement mortar (60); And

A second polymeric cement mortar (80) applied over the third geoscientific fiber (70);

.

The first geoscientific fiber 10 may be a geotextile, a geomembrane, a geogrid, a nonwoven fabric, a high density polyethylene (HDPE), a polyester, a polypropylene, a geocontainer, a geoback, a fiber and a PBD And any one selected from the group consisting of them can be used.

The first adhesive 20 may be at least one selected from the group consisting of an acrylic adhesive, a urethane adhesive, an epoxy adhesive, and a silicone adhesive.

The waterproof mat 30 may use at least one selected from the group consisting of polyvinyl chloride (PVC), polyethylene (PE), high density polyethylene (HDPE), bentonite, and polyurethane. The waterproof mat (30) plays a role of enhancing watertightness by preventing surface water, rainwater, soil degradation, soil inflow, and scour phenomenon at the time of rainy season.

The second adhesive (40) may be the same as the first adhesive (20).

The second geoscientific fiber 50 may be the same as the first geosynthetic fiber 10.

The first polymer cement mortar 60 comprises 35 to 45% by weight of ultrafine cement, 5 to 7% by weight of blast furnace slag, 5 to 7% by weight of calcium carbonate, 2 to 4% by weight of aluminate economics, A shrinkage reducing agent in an amount of 0.1 to 0.5 wt%, a fiber reinforcing agent in an amount of 0.1 to 0.2 wt%, an aggregate in an amount of 5 to 20 wt%, an acrylic resin in an amount of 0.5 to 1.0 wt% 5-7% by weight of resin and 25-30% by weight of water.

The ultrafine cement is very fine in comparison with the Blaine fineness (Blaine fineness) of ordinary Portland cement, and it is very fine in contact with water and the contact surface area is large, so that the hydration reaction of the cement is fast. Not only enhances long-term strength, but also reduces bleeding, lighten color and light weight.

The blast furnace slag has a low hydration heat and thus can prevent cracks. As the substitution rate increases, the pore radius decreases, thereby increasing the watertightness.

Since the calcium carbonate is a liquid phase polymer mortar, a filler is required to fill the gap between the aggregates by making it into a paste form. The calcium carbonate contributes to the improvement of the weight and strength of the polymer-cement mortar, maintains a balance of shrinkage expansion, and plays a role of suppressing the occurrence of cracks.

The aluminate economies have a very high reaction rate when they are in contact with water, so that when mixed with cement, general cement can provide the compressive strength obtained over several days over several hours.

The aluminate swelling agent is an admixture material that hydrates when kneaded together with cement and water to form ettringite or calcium hydroxide to expand the mortar or concrete. It suppresses drying shrinkage due to the rapid hydration reaction of concrete Thereby preventing occurrence of cracks and durability deterioration.

The fluidizing agent improves the fluidity without increasing the unit quantity of concrete and facilitates the pouring and compaction without deteriorating the quality of the concrete.

The dispersant is a kind of surfactant having a property of having a lipophilic property and a hydrophilic nature in the molecule, and it is an object of the present invention to provide a surfactant which uniformly disperses solid particles such as inorganic and organic pigments which are difficult to disperse in a liquid to prevent sedimentation or aggregation of solid particles, And forms a suspension.

The antifoaming agent serves to effectively reduce air content in the concrete.

The shrinkage reducing agent serves to reduce the surface tension of water to reduce the capillary tension generated in the capillary during drying, thereby reducing shrinkage.

The fiber reinforcing agent improves the brittleness property and improves the durability of the concrete by suppressing the firing and shrinkage cracking of the concrete and the mortar, and improving the tensile strength and the bending strength.

The aggregate has an aggregate having a particle size of 0.1 to 0.9 mm, and the concrete strength is improved when the aggregate is used.

The acrylic resin is a reactive resin having a double carbon bond through a polymerization reaction process, and is excellent in durability, heat resistance, chemical resistance, abrasion resistance, and improves porosity and permeability coefficient.
