Description

Grounding structure using Absorbent Pavement Geo-cell For Material And Rainforced Of Ground}

The present invention relates to a ground-permeable pavement structure using geocells for ground reinforcement and hollow fiber-reinforced permeation block, and more specifically, to reinforce the drainage function of rainwater that is permeated into the ground and through the rainwater that is permeated into the ground and stored. The present invention relates to a ground permeable pavement structure using ground reinforcement geocells and hollow fiber reinforcement permeable blocks that can suppress surface temperature increase due to evaporation and supply water to underground organisms and roadways.

In general, most of the city center is made of impermeable material, so the amount of rainwater that is permeated into the ground is insufficient, and the use of a large amount of groundwater is added, which is the source of global warming due to the rapid progress of desertification of the ground.

As a result, underground natural ecosystems are destroyed, and the ground is deformed or subsided frequently. Therefore, in order to solve these problems, it is urgently required to pave the permeability not only on roads but also on sidewalks.

Types of the method for packaging to have the permeability include ascon pavement, concrete pavement and permeable block, briefly described the method as follows.

First of all, ascon pavement is a method of laying a mixture of auxiliary base, asphalt fluid and aggregate at high temperature, which is easy to construct, shorten the air, and can be applied to a wide range of places such as sidewalks and roads. It is very vulnerable, weak durability and excessive maintenance costs, in particular, there is a problem that the geothermal temperature in summer rises sharply.

The concrete pavement is a method of mixing cement and sand and gravel and laying it on the upper surface of the sand. The concrete pavement has an advantage of being widely used because it is easy to purchase materials, good durability and low glass management cost, but the initial investment is excessive. In addition, as well as ascon packaging, there is a problem that the geothermal temperature in summer rises sharply.

The permeable block is a method of packing cement and sand is made of a small block by packing it on the upper surface of the sand, because it is compact, easy to install, partial repair is possible, various shapes and designs possible and low cost There is an advantage.

However, because the use is extremely limited, such as bicycle roads or sidewalks, and in general, the ground is not solid, so that the upper surface loses its flatness and partially settles, such as partial settlement of the ground due to permeation (or penetration). This easily breaks a lot of problems, and in particular, in the case of the permeable block, the foreign matter (fine particles of earth and sand) penetrates gradually with the rainwater and gradually accumulates to detail the permeation function within two to three years.

In addition, when there is no drainage function, the function is more and more fall off the original function completely becomes a problem to turn into a monster.

The present invention has been made to solve the above problems, while improving the water permeation function of the rainwater into the ground layer (ground), by increasing the groundwater content by storing or penetrating rainwater through the drainage structure provided in the ground layer It is intended to provide a ground-permeable pavement structure using georeinforced geocells and hollow fiber reinforced permeable blocks that can easily supply surface moisture and provide water to underground organisms and roadways by vaporization due to the increase in surface temperature. There is a purpose.

The present invention for achieving the above object,

Ground layer;

A soil layer laminated on the upper surface of the ground layer;

A geocell consisting of a mesh-like grid disposed on an upper surface of the soil layer, and a honeycomb-shaped mesh formed of multiple rows on the upper surface of the grid and filled with sand-based soil and gravel;

It is characterized by consisting of a plurality of hollow fiber reinforced permeable block is formed along the longitudinal direction having one or more drain holes to induce drainage, formed in multiple rows on the top surface of the geocell.

The present invention having the configuration as described above, by forming a geocell and hollow fiber reinforced permeable block on the upper surface of the soil layer, so that the rainwater quickly penetrates (penetration) to the basement during heavy rains (rainfall) so that the water on the road surface Since it is possible to prevent the swelling, in the case of a device that uses braking by road friction, such as a bicycle, it is possible to minimize the sliding phenomenon to minimize the braking distance.

In addition, since rainwater is quickly drained (infiltrated) to the road surface, there is no splash of water when walking, ensuring a safe walking space in a pleasant state at all times, and reducing the fatigue of the user due to the diffuse reflection of street lights or other lights. Can be.

In addition, by forming a drainage structure in the ground, the rainwater is permeated quickly (penetration) to prevent the backflow to the ground surface due to the groundwater saturation, and easy access to the ground organisms and roadway through the rainwater stored in the ground It is possible to minimize the increase of the surface temperature (geothermal heat) through a water supply and heat exchange between rainwater and radiant heat stored in the ground.

1 to 2 is a cross-sectional view and an exploded perspective view showing an installation state of the ground permeable paving structure using a ground reinforcement geocell and hollow fiber reinforced permeable block according to the present invention, Figures 3a to 3b The georeinforced geocells and hollow fiber reinforced permeable block according to the ground permeable pavement structure is a perspective view of the geocell and permeable block separately extracted.

The ground permeable pavement structure (1) using the ground reinforcement geocell and hollow fiber reinforced permeable block according to the present invention includes: a ground layer (10); A soil layer 20 stacked on an upper surface of the ground layer 10; Geometry consisting of a mesh-like grid 31 disposed on the upper surface of the soil layer 20 and a honeycomb mesh 32 formed of multi-row species on the upper surface of the grid 31 to be filled with sand-based soil and gravel. Cell 30; Formed along the longitudinal direction and having one or more holes 41 to induce drainage, it consists of a plurality of hollow fiber reinforced permeable block 40 formed in multiple rows on the top surface of the geocell 30, this figure 1 to 2 are shown.

The soil layer 20 laminated on the upper surface of the ground layer 10 is a well-known technique, and in the case of the present invention, the geocell 30 and the hollow fiber reinforced water permeable block on the upper surface of the soil layer 20 ( 40) are sequentially stacked.

According to the present embodiment, when the rainwater passes through the soil layer 20, the pollutant mixed in the rainwater is first filtered through the fine sand 21 layer of voids, and the rainwater passed through the sand 21 layer. Secondly, the voids quickly pass through the coarse gravel layer 22 and enter the ground layer 10.

The soil layer 20 may be any one selected from the sand 21 and the gravel 22 or the sand 21 and the gravel 22 may be sequentially stacked.

In this embodiment, the mesh grid 31 is disposed and fixed on the upper surface of the soil layer 20 composed of sand 21 and gravel 22, and covers the sand 21 to fix the grid 31 as necessary. You may.

In particular, the mesh 32 formed integrally with the upper surface of the grid 31 is filled with sand-based soil and gravel for reinforcing the ground, and the sand drainage and gravel through the sand-based soil and gravel is about 16%, bearing strength and frictional force. Since about 30% is improved, rainwater that has passed through the hollow fiber reinforced permeable block 40 can be prevented from weakening the ground when it penetrates into the basement. Blocking the movement by the infiltration water in advance to perform the function to solve the scour phenomenon and ground subsidence, as shown in Figure 3a.

The hollow fiber-reinforced pitcher block 40 disposed on the top surface of the geocell 30 forms a block body by mixing and pouring aggregates having the same diameter and reinforcement materials of a synthetic resin material having a predetermined length to form a block body. Hole 41 is formed along the longitudinal direction in the center of the main body for rapid permeation, as shown in Figure 3b.

In this embodiment, any one of the polymer fibers PP (Plypropylene), PE (Polyethylene), PC (Polycarbonate) is selected as the reinforcing material for structural reinforcement against shear and bending stress.

In particular, at least one hole 41 is provided in the hollow fiber reinforced water permeable block 40, and through the hole 41 to minimize clogging due to rainwater and foreign matter passing between the pores (not shown) during heavy rain. It can be, and can fundamentally eliminate the water pooling and drainage capacity is lowered on the upper surface of the hollow fiber reinforced permeable block 40 due to the backflow and stagnation of rain water.

On the other hand, as shown in Figure 1, the hollow fiber reinforced permeable block 40 is made of a different upper and lower thickness, which is the prime mover or when applying the hollow fiber reinforced permeable block 40 to the sidewalk In view of the load, such as a person passes, some strength and support should be provided, so that the upper portion is formed somewhat thicker than the lower portion while substantially reinforced with polymer fibers.

In the present embodiment, the hollow fiber reinforced water permeable block 40 is applied as a specific embodiment, but if necessary, permeable concrete, grating, etc., which can perform the same function as the hollow fiber reinforced water permeable block 40. Since it can be applied, it is preferable not to limit to the hollow fiber reinforced permeable block 40.

By forming the geocell 30 and the hollow fiber reinforced permeable block 40 on the upper surface of the soil layer 20 as described above, even if rainwater is continuously supplied during heavy rain (rainfall), the rainwater is geocell 30 and The hollow fiber reinforced water permeation block 40 quickly penetrates (penetrates) into the basement to prevent water from accumulating on the road surface, and furthermore, when it is applied to a bicycle road, the water does not accumulate on the pavement surface, so that the wheel slips. As the phenomenon can be suppressed as much as possible, the braking distance can be minimized and safe driving can be induced.

In addition, since rainwater is quickly drained from the road surface, there is no splash of water, thereby ensuring a comfortable and safe walking space, and reducing fatigue of a user due to diffused reflection of street lights or other lights.

Figure 4 is a cross-sectional view showing another embodiment of the ground-penetrating pavement structure (1-1) using the ground reinforced geocells and hollow fiber reinforced permeable block according to the present invention, as follows with reference to the drawings. .

Non-woven fabric 52 is installed to pass water and block foreign substances therein, and the air gap is disposed inside the non-woven fabric 52 in which air gaps 53 are provided so that rain water can be permeated. The ash 53 is wrapped in a nonwoven fabric 52 so as not to be discharged (exposed).

The air gap 53 is to store rainwater during rainfall (rainfall) to prevent flow to the river area at the time to prevent flooding of the river, and during the dry season to slowly penetrate the stored rainwater underground, solar heat In addition to suppressing the rise of geothermal heat due to serves to supply moisture to the land organisms and roadside trees.

The pore material 53 is any one selected from the crushed glass or crushed plastic or drainage structure (53a) that is relatively large porosity and can perform the drainage function smoothly, in the case of the present embodiment the pore material 53 It is described that any one of the crushed glass or crushed plastic or drainage structure (53a) is applied to, but any material capable of performing the same function as the void material 53 is applicable, if necessary, limited to this It is not desirable to do so.

The drainage structure 53a includes a frame 53a-1 forming an exoskeleton; It is composed of a truss (53a-2) formed to cross the inside of the frame (53a-1) to support the frame (53a-1) from the external force, as shown in Figures 5a to 5b.

In the present embodiment, the drainage structure 53a is disposed in the drainage passage 51 formed along the longitudinal direction in the ground layer 10, and the outer surface of the drainage structure 53a is wrapped and protected by the nonwoven fabric 52. In case of rainfall, rainwater flows into the interior as much as possible, and during the dry season, the rainwater stored in the interior is gradually penetrated into the basement.

Although the shape of the said drainage structure 13a is shown by the cube, since it can manufacture in various shapes as needed, it does not limit about a shape and a shape.

As mentioned above, by forming the drainage structure 50 composed of the drainage passage 51, the nonwoven fabric 52, and the pore material 53 in the ground layer 10, to minimize the pollutant contained in the rainwater during rainfall Clean water is to be permeated, clean rain water is gradually stored through the drainage passage 51 to supply sufficient moisture to the land organisms and roadsides, and to prevent the increase of the surface temperature (geothermal heat) through the stored rain water as much as possible Can be.

On the other hand, the drainage structure (53a) is different in the installation position according to the geological structure, if the geological layer is soft, the rainwater does not quickly seep into the basement in the case of the region flowing back to the ground surface of the ground layer (10) When the drainage structure 53a is provided in the drainage passage 51 and the ground layer is a hard (impermeable layer), it is preferable to arrange the drainage structure 53a in the soil layer 20, as shown in Figs. 5A to 5B.
