The present invention relates to a functional roadside protection structure, and more particularly, to a roadside protection structure for a functional road, which can prevent damage to roadside trees by securing permeability and strength, The present invention relates to a functional roadside waterproofing structure capable of solving difficulties and a construction method thereof.

Generally, the roadside trees that are planted along the inner city streets to improve the surrounding landscape and purify the air are supplied with moisture by raining in the rain.

However, due to the urban pavement block and the asphalt, the ground surface provided by the roadside is limited, and the rainwater is limited. As a result, the water supply to the roadside tree is insufficient. In order to prevent this, water is directly supplied by a manager or a separate water supply facility depending on the situation, but there is a problem that a lot of time, manpower, and equipment are required for such a job and a lot of tax is wasted. In addition, the growth of weeds against the purpose of improving the surrounding landscape has caused damage to the landscape of the scenery and complaints.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a sectional view of a construction of a functional roadside protection structure according to the present invention. Fig.

As shown in FIG. 1 and FIG. 2, the functional roadside waterproofing structure according to the present invention comprises a ground reinforcement layer 10 and a polymeric roadside waterproofing layer 20.

The soil strengthening layer (10) is formed by the installation of a soil strengthened soil (installation thickness 10 mm to 150 mm) in which a soil reinforcement material and a natural soil (local soil) are mixed.

The ground reinforcement is composed of a mixture of 100 parts by weight of aggregate (recycled aggregate), a blast furnace slag powder, a fluidized bed boiler furnace, a paper ash, an alpha type hemihydrate gypsum powder, a calcium sulfo-aluminate (CSA) powder, 5 to 10 parts by weight of a solid solidifying agent composed of 5 to 10 parts by weight of the reaction liquid and 5 to 10 parts by weight of the reaction liquid.

Recycled aggregate is a concrete recycled aggregate selected from aggregates of single particle size (5mm ~ 10mm, 10mm ~ 15mm, 15mm ~ 20mm). It provides optimum particle size of granular reinforcement, reduction of amount of reaction liquid used, securing of permeability, .

The solid solidifying agent is used for solidifying recycled aggregate and natural soil materials, and since all of the above-mentioned materials function as solidification, they can be used alone from one of the above-mentioned materials, but it is preferable that two or more are mixed in consideration of supply and demand , And in the case where two or more of them are used, it is freely adjustable within the range of 5 to 10 parts by weight.

When the amount of the solid solidifying agent is less than 5 parts by weight based on 100 parts by weight of the recycled aggregate with a particle size of 3,000 to 5,000 Blaine (cm ² / g), the workability is not good because the solidification is delayed. It is difficult to mix uniformly and workability is poor.

The reaction liquid, which can initially accelerate the curing of the solidifying agent used in the ground reinforcement and increase the strength, is used for uniform stabilization and curing of the recycled aggregate and solid solidifying agent, and is used for 100 parts by weight of methylbutyl acrylate 30 to 60 parts by weight of acrylonitrile monomer, 10 to 30 parts by weight of methacrylic acid monomer, 0.5 to 3 parts by weight of catalyst, 1 to 2 parts by weight of calcium nitrate and 1 to 5 parts by weight of calcium oxide.

Methyl butyl acrylate is used for adhesion of materials.

Acrylonitrile monomers are used for mixing of materials.

The methacrylic acid monomer is used to improve the weatherability of the reaction solution.

The catalyst is used for the smooth reaction of the materials, and titanium dioxide, sodium hydroxide, iron oxide, barium oxide and the like can be used as the catalyst material.

Calcium nitrate and calcium oxide are used to improve the durability of the reactants formed by the inorganic polymer reaction.

The mixing ratio of the above-mentioned materials is for each function, and if it is out of the above range, there arises a problem of adhesion, uniformity and weatherability.

If the reaction solution having such a composition is out of the range of 5 to 10 parts by weight with respect to 100 parts by weight of the recycled aggregate, the reaction between the recycled aggregate and the solid-state solidifying agent is weak, so that the adhesive strength is lowered and uniform strength can not be obtained due to excessive reaction .

The ground reinforcement is used in an amount of 40 to 60% by weight based on 100% by weight of the ground reinforcement. When the amount is less than 40% by weight, the permeability and the strength of the ground are low. And is not friendly with the paper.

The natural soil is obtained from the ground where the roadside tree (1) is planted. Since the natural soil is obtained through the planarization work of the ground, it is possible to eliminate the cost and work for disposal. When less than 40% by weight is mixed, It can not provide a friendly environment for the growth of aquatic plants. When the amount exceeds 60% by weight, the strength is weak and it is impossible to protect the aqueducts and the polymer roadside water protection layer 20.

The polymeric roadside protection layer 20 is composed of a polymer protective material.

The polymer protective material is laid on the ground reinforcement layer 10 (for example, 10 mm to 150 mm, not limited to this thickness) using a composite material (non-yellowing) of aggregate and a polymer composite to form a layered structure. That is, since the ground reinforcement soil and the polymer protective material are installed without being used in the form of a regular shape, they can be customized to the conditions (size, shape, etc.) of the roadside planting area.

Polymeric roadside protection layer can be used in the form of a panel without being laid. The molding temperature is 20 ~ 30 ℃ for 6 hours to 12 hours for curing.

The aggregate may be at least one of soybean gravel, oak mill, white mill, germanium mill, dark red mill mill, American rock mill, tin mill, recycled aggregate, and the like. The particle size of the particles is 3 to 5 mm and the particle size is 5 to 10 mm.

Polymer composite is composed of 60 to 80% by weight of an isocyanate polymer, 5 to 30% by weight of a polypropylene polymer, and 0.5 to 15% by weight of an additive, based on 100% by weight of the polymeric resin composition. It is used for securing permeability.

The isocyanate-based polymer used in the polymer composite is a non-yellowing material having excellent fire resistance and acid resistance and improved bonding strength. The polypropylene-based polymer has an effect of preventing brittle fracture by exhibiting excellent toughness and strength at room temperature have.

As the additive, a hardening accelerator is used to adjust the hardening time from 6 hours to 12 hours. As the hardening accelerator, calcium carbonate, calcium hydroxide, calcium nitrate, calcium oxide and the like are applied.

The non-yellowing polymer composite is mixed with 10 to 20 parts by weight of the aggregate based on 100 parts by weight of the aggregate. When less than 10 parts by weight is mixed, the effect of improving the strength is weak. When the amount is more than 20 parts by weight,

The non-yellowing polymer composite is reacted through the thermal process by maintaining the temperature condition of 70 ~ 90 ° C for 5 ~ 10 hours in the mixed state of the materials, and then mixed with the aggregate on the ground reinforcement layer 10 and reacted.

In the drawing, reference numeral 2 denotes a circumferential stones provided on the periphery of the row of planting trees (1), and 3 denotes a packaging layer (press block).

The construction method of the functional roadside waterproofing structure according to the present invention is as follows.

1. Planarization.

The roadside 1 is plowed out of the soil to be planted and the floor is leveled flat for the construction of the soil strengthening layer 10. In this process, natural soil, which is a soil generated from the ground, is used as the material of the soil strengthened soil.

2. Construction of reinforced ground layer.

(2 or more of blast furnace slag powder, fluidized bed boiler furnace, paper ash, alpha type hemihydrate gypsum powder, calcium sulfo-aluminate (CSA) powder, quicklime, and lime) with respect to 100 parts by weight of the recycled aggregate. 5 to 10 parts by weight are mixed to prepare a ground reinforcement, and the natural soil obtained in the previous step is mixed and mixed at a mixing ratio of 50% by weight of the ground reinforcement and 50% by weight of natural soil. For example, 10 parts by weight of a solid solidifying agent is mixed with 100 parts by weight of a recycled aggregate to prepare a ground reinforcement, and the natural soil is mixed in the same weight ratio to prepare a ground reinforcing soil.

The ground reinforcement layer 10 is constructed by laying the ground reinforcement soot (50 wt% of the ground reinforcement material and 50 wt% of the natural soil) at a thickness of 10 mm to 150 mm (50 mm) on the ground leveled in the previous step.

3. Construction of protective layer of polymeric roadside tree.

(For example, 70% by weight of an isocyanate-based polymer, 25% by weight of a polypropylene-based polymer, 5% by weight of an additive), 60 to 80% by weight of an isocyanate-based polymer, 5 to 30% by weight of a polypropylene- 15 parts by weight of the polymer composite was mixed with 100 parts by weight of the aggregate material, and the polymer protective material as the mixture was reacted at a temperature of 80 DEG C for 8 hours. Then, the polymer protective material was placed on the ground reinforcement layer 10 as a finisher Thereby constructing the polymeric roadside protection layer 20. By such construction, the roadside protection structure by the layered structure of the polymer roadside protection layer 20 and the ground reinforcing layer 10 is completed from the upper part.
