Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a packaging material for packing soil using a grid,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a packing material for a soil packing and a method for installing a packing material for a soil packing. More particularly, the present invention relates to a packing material for a soil packing using an environmentally friendly and durable grid by using soil for packing roads and walking paths.

In general, asphalt and concrete are mainly used for packing roads and walkways, and thus most roads and walkways are packed in concrete or asphalt, not only in metropolitan areas, in local cities, and in rural areas.

Such concrete or asphalt is too hard on the pavement surface to reduce walking feeling, and as it gets hotter, it raises the ambient temperature and causes heat island phenomenon especially in the city center. Also, since concrete and asphalt contain harmful components to the human body, they are not environmentally friendly.

For example, when the temperature of the surface of the packaging layer is measured under the same conditions, the surface temperature is shown in the order of elastic rubber chip packing material> urethane packing material> asphalt packing material> color water permeable cone packing material> soil packing material.

Accordingly, in recent years, considering the nature-friendly surrounding environment, when constructing walking trails, park trails, and walking paths of apartment complexes, soil pavement construction is being carried out by using eco-friendly soil.

The packaging materials used for general soil packaging are packed with soil and solid fire to solidify the soil. However, the cement fire is vulnerable to the East Sea, cracks due to drying shrinkage occur, and toxic components are contained in the human body.

Particularly, the conventional packaging material is composed only of soil and cement based fire, so that the durability thereof is deteriorated and it is easily damaged by repetitive passage of people or vehicles.

On the other hand, as an alternative for overcoming the disadvantages of the cement fireproofing as described above, there have been proposed various types of fireproofing fireproofing materials such as those disclosed in Korean Patent Publication No. 10-1154280, Korean Patent Registration No. 10-1139089, Korean Registered Patent Application No. 10-922081 There has been proposed a soil paving composition to which a topping agent is applied.

However, the composition for soil pavement according to the prior art has a merit that it is made of environment-friendly material instead of cement fireproofing, but it takes a long time to cure and has a disadvantage that it can not be compaction at the time of compaction.

In particular, the composition for soil pavement of the prior art does not have a reinforcing member such as a core material and is composed only of soil and fireproofing.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted.

1, a packaging material 10 using a grid according to an embodiment of the present invention includes a first laying layer 100, a grid reinforcing body 200, and a second laying layer 300, .

Specifically, the packaging material 10 for a soil using the grid according to the present invention comprises a soil, a soil stabilizer, a cement, an ilite mineral and water mixed at a predetermined ratio, The grid 100 includes a grid reinforcing body 200 formed in a lattice-like mesh body and covering the upper surface of the first laying layer 100, And a second laying layer (300) placed in a laminated state along the upper surface of the reinforcing member (200).

As shown in FIG. 1, the first and second laying layers 100 and 300 are disposed on the foundation floor 5 at the construction site, The laying layers 100 and 300 preferably crush the field soil to a uniform particle size to constitute the soil.

If the grains of the soil are rough or lack of fine particles, the stability is insufficient, and the compaction operation described later is incompletely performed.

In addition, the above-mentioned laying layers 100 and 300 may comprise 5 to 10 parts by weight of a soil stabilizer containing inorganic oxide and monofilament polypropylene fiber in powder form, 10 to 15 parts by weight of ilite mineral and 5 to 10 parts by weight of water.

Illite minerals are mica-type minerals belonging to the monoclinic system and have a hardness of 1 to 2, a specific gravity of 2.6 to 2.9, and streaks of white.

These ilite minerals absorb and decompose heavy metals, adsorb, decompose and deodorize toxic gases, and have antibacterial properties such as viruses, bacteria and fungi. They have a characteristic of generating far infrared rays and a large amount of anions and oxygen, SiO ₂ , Al ₂ O ₃ , Fe ₂ O ₃ , CaO, MgO, K ₂ O, and the like.

Such ilite minerals are preferably crushed to a particle size of 10 to 100 mu m, and they can be mixed into a mixed soil through a purification process by, for example, magnetic force sorting, acid treatment, electrostatic sorting and floating sorting. It is preferable that 10 to 15 parts by weight of the ilite mineral is mixed with 100 parts by weight of the soil in a pulverized and purified state.

Generally, a mixing ratio of 15 to 25 parts by weight of cement is required for 100 parts by weight of soil for the development of strength. However, since the present invention uses a soil stabilizer to increase the compressive strength of the packaging material while having a smaller mixing ratio of cement, The durability and the functionality are rather improved even if the amount is relatively small, and the environment-friendliness can be improved because the generation of carbon can be minimized and harmless to the human body and pollution of the surrounding environment can be prevented.

The soil stabilizer is preferably composed of inorganic oxides in the form of powder, and preferably contains monofilament polypropylene fibers, and is preferably mixed with 5 to 10 parts by weight based on 100 parts by weight of the soil. If it is used in an amount less than the above-mentioned amount, the effect of the soil stabilizer can not be sufficiently exhibited.

These soil stabilizers are mixed with cement, ilite minerals and water mixed in the soil in a mixed state, and solidify the soil as they are compacted and cured.

Soil stabilizer improves the compressive strength of soils, cement and illite minerals and absorbs the heavy metals eluted from the cement components. It protects soil and water from contamination and is eco-friendly. .

A concrete method for forming the laying layers 100 and 300 or a method for calculating the mixing ratio of the soil stabilizer, cement, ilite mineral and water will be described later.

The grid reinforcing member 200 is a reinforcing member that is embedded between the laying layers 100 and 300 and functions as a core, and is made of at least one of polyester fiber, glass fiber, and carbon fiber, And a coating layer 220 composed of at least one of a fiber layer 210 and a polyvinyl chloride resin, an acrylic resin, a latex resin or a rubber resin and coated on the outer surface of the fiber layer 210.

1, the grid reinforcement 200 is stacked on top of the first laying layer 100, and the second laying layer 300 is stacked on top of the grid reinforcement 200. As shown in FIG. That is, the rig strengthening body 200 is embedded in the interposed between the laying layers 100 and 300.

As shown in FIG. 2, the grid reinforcing member 200 is formed in a grid-like web by weaving in a weft and an oblique direction so that the first laying layer 100 is laid on the foundation floor 5, (100). &Lt; / RTI >

That is, since the grid reinforcing member 200 is formed of the fibrous layer 210 and is reinforced by the coating layer 220, the grid reinforcing member 200 is not easily broken, thereby improving the durability of the laying layers 100 and 300.

In addition, since the laying layers 100 and 300 are cured by curing with the grid reinforcing member 200 interposed therebetween, the cushioning layers 100 and 300 can be cured firmly to improve the compressive strength. In addition, As the rigidity is reinforced by the coating layer 220, the compressive strength and durability can be further improved.

On the other hand, the grid reinforcement member 200 may be formed of a rigid plastic material, or may be formed of a metal material and may be formed of a grid-like net.

And a vertical stiffener (230) that is vertically fixed to the grid reinforcement (200) and provides a vertical supporting force in the packing material for the soil, the vertical stiffener comprising a net of the grid reinforcement And vertical support rods 240 having a rigid rod shape, which are formed in a plurality of units and are equally spaced apart from each other in a vertical state.

As shown in FIG. 3, the vertical support rods 240 may be formed in a rigid rod shape. For example, the vertical support rods 240 may be vertically fixed to the binding knot of the grid reinforcement 200, And can be fixed to the binding portion of the grid reinforcing member 200 through the fixing member.

That is, as shown in FIG. 4, the packing material 10 for a dirt can be reinforced with durability to prevent shrinkage and expansion by forming a packing layer with the grid reinforcing member 200 and the vertical stiffener 230 interposed therebetween , Even when a vertical load is applied, breakage or deformation can be prevented.

As shown in FIG. 4, the vertical support rods 240 may have irregularities 241 along the longitudinal direction thereof to enlarge a contact area with the mixed soil constituting the packing material 10. Accordingly, the vertical support rods 240 can be embedded in the packing material 10 in a more solid state through the concave and convex portions 241, thereby providing a sufficient strength.

Meanwhile, as shown in FIG. 5, the grid reinforcement 200 may be formed such that the distance W1 (W2) of the net becomes gradually narrower from the center toward the rim side.

In other words, the grid reinforcing member 200 can be formed so that the interval W1 of the net on the side of the rim is gradually narrowed with respect to the interval W2 of the central net, and can be embedded tightly toward the rim of the packing material 10 have.

Accordingly, the packaging material 10 of the soil packing can be cured while being solidified more firmly, so that breakage or deformation can be prevented.

Hereinafter, a method of installing a packing material for a soil using the grid according to the present invention will be described with reference to FIGS. 6 and 7. FIG.

The method for installing the packing material for soil packing according to the present invention is characterized in that the soil packing inspection step S10, the sample soil production step S20, the sample soil property inspection step S30, the mixing ratio calculation step S40, A soil preparation step S50, a drainage trap construction step S90, a package layer formation step S60, a compaction step S70, a density test step S100 and a curing step S80.

Specifically, the method of installing the packing material for the soil packing using the grid according to the present invention is characterized in that the particle size distribution test, the plasticity test, the humidity test, the AASHTO density test, (CCS) test, a uniaxial compressive strength (UCS) test, a soil physical property test step (S10) of obtaining the physical and mechanical properties of the sampled soil, (S20) a sample soil preparation step (S20) for preparing a sample soil by performing compaction and curing after mixing the stabilizer, cement, ilite mineral and water, ) Test and unconfined compressive strength (UCS) tests are carried out, and the soil stabilizer, the cement and the clay (S30) of repeatedly performing the sample soil preparation step, the CBR test, and the unconfined compressive strength (UCS) test (S30) while increasing the mixing ratio of the sample soil properties Based on the mixing ratio of the soil stabilizer, cement, ilite mineral and water obtained in the inspecting step, the mixture of the field soil and the soil stabilizer, the cement, the ilite mineral and water A basic soil preparation step (S40) of dividing the field soil of the construction site into a predetermined depth to form a foundation floor, finely crushing the ground soil in a uniform state, and preparing a foundation soil S50), a drainage trap construction step (S90) of constructing a drain trap in which rainwater is drained along the center or both sides of the roadbed constituting the foundation floor, (S60) of forming a packing layer by mixing the soil stabilizer, the cement, the ilite mineral and water into the base soil while placing the soil on the foundation floor (S60), and the surface of the packing layer A compaction step (S70) of performing a compaction step of measuring a density of the packaging layer or the foundation floor and repeating the compaction step until the density of the packaging layer or the foundation floor reaches a set density (S100), and a curing step (S80) of curing the packaging layer as the compaction operation is completed,

The packaging layer forming step (S60) comprises: placing a part of the base soil at a construction site; and applying the soil stabilizer, the cement, the cement, and the soil to the base soil based on the mixing ratio calculated in the mixing ratio calculating step (S40) (S61) for forming a first laying layer by mixing the iridite mineral and water, a grid installation step of installing a grid reinforcing body formed of a lattice-like net in a laminated state on the upper surface of the primary laying layer (S62) and a remaining portion of the basic soil is placed on top of the grid reinforcement, and the soil stabilizer, the cement, the ilite mineral And a second laying layer forming step (S63) for forming a second laying layer by mixing water.

The soil physical property inspection step (S10) is a step of acquiring the physical and mechanical properties of the soil collected from the field soil at the site where the packaging is to be constructed. This physical property inspection step (S10) is a step for analyzing the underlying on-site soil to check for soil damage or problems, and corrects the problem when there is a problem. The soil, soil stabilizer, cement, It is used as data for setting the blending ratio.

The soil property inspection step (S10) is preferably carried out in a laboratory by collecting the soil at a depth of 70 to 150 mm at the construction site and carrying it in a closed state. Specifically, the particle size distribution inspection, the plasticity test, the humidity test, the AASHTO Density test, CBR test, and unconfined compressive strength test (UCS).

First, the particle size distribution test is to examine the distribution of fine particles and coarse particles. When the distribution of fine particles and coarse particles is unevenly distributed, the mechanical stability is insufficient. In the present invention, it is checked whether particles of a predetermined size are not distributed too much and are evenly distributed from a maximum to a minimum. If a good particle size distribution can not be obtained, some of the soil collected in another region is mixed and used.

This particle size distribution test usually analyzes the particle size of the on-site soil using sieves of NO.4, NO.10, NO.20, NO.40, NO.60, NO.100, NO.120 and NO.200 , The NO. If the ratio of soil passing through 200 sieve is more than 50%, it is still used. If it is less than 50%, it is preferable to use some soil collected from other area.

The above-mentioned plasticity test tests the reactivity of the soil in the field with the affinity with water, which will be used to calculate the ratio of soil stabilizer, cement and ilite minerals to various resistance of the field soil. This plasticity test can be obtained through the Atterberg limit.

The above-mentioned humidity test and AASHTO density test play an important role in determining the compaction of the on-site soil by testing the density ratio of moisture and field soil. Higher soil densities improve cutting resistance and elastic modulus and reduce or prevent water penetration.

The above-described CBR test and unconfined compressive strength (UCS) tests are conducted to analyze the resistance and consistency of the field soil. Specifically, we tested the resistance of field soil or the consistency of field soil through the CBR test and the UCS test to determine the thickness of the pavement and the bearing capacity of the pavement to determine the soil stabilizer, Cement, ilite mineral and water can be determined.

Here, the CBR is expressed as the ratio of the bearing capacity to the calorific value. The test unit load required to penetrate a piston having a diameter of 5 cm to a predetermined depth (2.5 mm, 5.0 mm) As a percentage.

The results of this study are summarized as follows: 1) In the case of the uniaxial compressive strength (UCS) test, the CRB test is used to determine the thickness of the pavement and the bearing capacity of the support base. It is used to quickly obtain the value of compression resistance of the soil.

The sample soil preparation step (S20) is a step of mixing and stirring the soil stabilizer, cement, ilite mineral and water into the soil based on the data obtained through the various tests in the soil physical property testing step (S10) And then the sample is prepared by curing the mixture for a predetermined time while exposing the compaction mixture to air. At this time, the compaction sample should be placed underneath a sack or a wet piece of wood to prevent it from drying too quickly and not producing adequate resistance.

The sample soil property testing step S30 is a step of testing the resistance of the sample soil while performing the above-mentioned CBR test and unconfined compressive strength (UCS) test, and when the sample soil reaches the set compressive strength (CBR) test and the unconfined compressive strength (UCS) test are repeated after repeating the above-described sample soil preparation step (S20) while increasing the mixing ratio of the soil stabilizer, ilite mineral and cement.

For example, the sample soil is preferably immersed in water for 4 days in order to perform the CBR test after the curing is completed. In order to perform the unconfined compressive strength (UCS) test, It is desirable to shrink it.

The mixing ratio calculating step S40 is a step of calculating the mixing ratio of the soil, soil stabilizer, cement, ilite mineral and water at the construction site. The soil stabilizer, cement, ilite mineral And mixing ratio of soil, soil stabilizer, cement, ilite mineral and water based on the mixing ratio of water, the area and depth of the construction site, and the application.

For example, in case of a general walkway, the soil stabilizer is preferably mixed at a mixing ratio of 5 to 10 parts by weight with respect to 100 parts by weight of the soil, and water is mixed at a mixing ratio of 5 to 10 parts by weight with respect to 100 parts by weight of the soil . Preferably, the cement is mixed at a mixing ratio of 5 to 10 parts by weight with respect to 100 parts by weight of the soil, and the ilite mineral is mixed at a mixing ratio of 10 to 15 parts by weight with respect to 100 parts by weight of the soil.

In the basic soil preparation step (S50), the foundation soil (5) is formed by dipping the field soil of the construction site to a predetermined depth, and ground soil is uniformly ground to prepare a foundation soil.

The basic soil preparation step (S50) is based on the data obtained in the particle size distribution test of the field soil during the test performed in the soil property testing step (S10).

Specifically, in the case of the soil preparation step (S50), when the soil is judged to be inadequate for the pavement construction in the particle size distribution test, the external soil should be further mixed and used. It is desirable to perform the crushing operation so that the particle size of the field soil becomes uniform after piercing into a thickness range of ~ 150 mm.

The reason why the depth of field soil is limited to the above-mentioned threshold is because the minimum pavement thickness should be 70 mm or more in pavement construction work, and the lower limit value is 75 mm. In case of the ground of 150 mm or more, soil density is high It is necessary to use expensive equipment.

The draining trap construction step S90 is a step of forming drainage traps 8 along both sides or the center of the bedrock constituting the foundation floor 5 as shown in Fig. 2 to prevent rainwater from accumulating on the packaging layer and to drain . Here, the configuration of the drain trap 8 may be adopted a configuration known in the art to which the present invention belongs.

The packaging layer forming step S60 is a step of forming the packaging layer 10 as shown in FIG. 1 by mixing the soil stabilizer, cement, ilite mineral and water into the foundation soil while laying the foundation soil on the foundation floor 5 Thereby forming a packaging layer.

1 and 2, the pavement layer forming step S60 includes a first laying layer forming step S61 for laying the first laying layer 100 on the foundation floor 5, A grid installation step S62 for laminating the above grid reinforcing member 200 on the upper surface of the laying layer 100 and a second laying layer 300 for laminating the second laying layer 300 on the grid reinforcing member 200, Forming step S63.

The first soil layer formation step (S61) and the second soil layer formation step (S63) may include a soil installation step (S61a) for laying the foundation soil, a soil stabilization step (S61a) A stabilizing agent and a cement injecting step (S61b) uniformly sprayed on the surface of the soil, a first agitation step (S61c) of agitating the basic soil, the soil stabilizer and the cement, (S61d), a second agitation step (S61e) for agitating the first mixed soil and the ilite mineral, and a second agitation step (S61b) for mixing the first mixed soil and the ilite mineral, (S61f) for introducing water prepared according to the mixing ratio into a second mixed soil in which the basic soil, soil stabilizer, cement and ilite mineral are mixed, a third water mixing step (S61f) for mixing the second mixed soil and water And a planarizing step S61h of flattening the surface of the third mixed soil obtained through the semi-step S61g to form the primary laying layer 100 or the secondary laying layer 300 .

7, a portion of the ground ground ground to a uniform particle size is laid along the foundation floor 5 (S61a), and the mixing ratio calculation step (S61) S40), the prepared soil stabilizer and cement are uniformly sprayed on the surface of the basic soil (S61b), and the basic soil, the soil stabilizer and the cement are stirred (S61c).

At this time, it is preferable that the soil stabilizer, the cement and the ilite mineral are put in a dried state. In some cases, the performance of the soil stabilizer, cement and ilite minerals may be abnormal. When the mixing ratio calculated in the mixing ratio calculating step (S40) is adjusted to include moisture, It can not be secured.

On the other hand, when mixing the soil stabilizer, cement, and ilite mineral, it is preferable to use a mechanical spreader to mix the soil stabilizer, the soil stabilizer, the cement and ilite minerals, It is preferable to continuously mix in situ soil, soil stabilizer, cement and ilite minerals while mixing them.

When agitating basic soil with soil stabilizer, cement and ilite minerals, agitate well to the maximum depth of construction and use equipment such as a planter, a lump crusher or a tiller with rotating blades, , Cement and ilite minerals are repeatedly stirred.

Then, the first laying layer forming step S61 is carried out as shown in FIG. 7, by adding the prepared ilite mineral to the mixed soil according to the mixing ratio calculated in the mixing ratio calculating step S40 described above (S61d) And stirred in the first mixed soil (S61e).

Thereafter, the prepared water is charged into the second mixed soil according to the mixing ratio calculated in the mixing ratio calculation step S40 (S61f), and after the charged water and the second mixed soil are stirred (S61g) The surface of the mixed soil is planarized (S61h) to form the primary laying layer (100).

In the first soil layer formation step (S61), water is preferably sprayed in order to mix the second mixed soil and the water evenly, and it is preferable to carry out stirring in the middle of water spraying.

5 to 10 parts by weight of the soil stabilizer is added to 100 parts by weight of the base soil and 5 to 10 parts by weight of the cement is added to 100 parts by weight of the base soil. In the step of adding the ilite mineral, 10-15 parts by weight of the ilite mineral is added to 100 parts by weight of the base soil, and 5 to 10 parts by weight of the water is added to 100 parts by weight of the base soil. .

The grid installation step S62 is performed to cover the grid reinforcing member 200 as shown in FIG. 2 on the upper part of the first installation layer 100 formed by the above-described first installation layer formation step S61 .

The second laying layer forming step S63 is performed by laying the remaining portion of the base soil used in the first laying layer forming step S61 along the upper surface of the grid reinforcing body 200 and removing the soil stabilizer, And water is mixed to form a second laying layer 300. The second ground layer formation step S63 is performed in the same manner as the first ground layer formation step S61 described above, so that detailed description will be omitted.

In the compaction step S70, the surface of the packaging layer 10 formed through the packaging layer formation step (S60), that is, the surface of the second installation layer 300, is compacted with a compaction machine.

For example, in the soil compaction step (S70), it is preferable to compose the compaction sufficiently by using a voltage type compaction apparatus in case of a soil having a large amount of sand components, and a voltage type or vibration roller may be used when the particle size distribution is good.

The compaction step S70 is preferably performed continuously while covering the entire width of the second laying layer 300. The shape and rolling range of the compaction equipment used can be varied depending on the operation .

The compaction step (S70) is performed while removing holes, grooves, hard surfaces, and the like that occur on the surface of the second laying layer (300) during the compaction operation. When moisture is evaporated during compaction, Sprinkle and adjust.

The density test step S100 is performed by measuring the density of the compaction layer 10 or the foundation floor 5 through the above-described AASHTO density test as the compaction step S70 is completed, And the compaction step S70 is repeated until the density of the foundation floor 5 reaches the set density.

In this density testing step (SlOO), the density of the packaging layer (10) is measured by AASHTO Mod. Density is 100%, and the density of the foundation bottom layer 5 is higher than that of AASHTO Mod. It is preferable to perform the process until the density reaches 97%.

The curing step (S80) is a step of curing the packaging layer in which compaction is completed, and it is preferable to cure for 2 to 4 days. At this time, it is preferable that the curing step S80 is performed by spraying water on the surface of the packaging layer 10 (the second laying layer 300) in order to prevent the packaging layer 10 from being dried quickly. If the packaging layer 10 is dried too quickly, it will adversely affect the stabilization mechanism. Alternatively, if heavy rain is expected during the curing period, it is preferable to cover the packaging layer 10 with a cover.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various changes, substitutions, and alterations can be made therein without departing from the spirit of the invention.
