Description

Water permeable block and producing method

The present invention relates to a block, and more particularly, to a water-permeable composite block consisting of two layers having different porosities and simultaneously satisfying the conditions of water permeability and strength, and a method of manufacturing the same.

In general, a conventional sidewalk block or pitcher cone installed in a sidewalk, a park, a plaza, and the like separated from a driveway has a problem that water is hardly pitched when installed in a sidewalk, a park, a plaza, or the like.

That is, in the case of the conventional sidewalk block and the pitcher cone, there is a problem that the pitcher space is easily blocked due to the foreign matter such as dust or dirt, and the pitcher is not properly made.

Generally, the sidewalk block is made by mixing aggregates such as crushed stone with sand and cement in a predetermined ratio and dipping it in a mold having a predetermined shape to harden the block. The sand is placed on the ground and fixed to the ground so that it can be repeatedly arranged to interlock with each other. Therefore, moisture and air can hardly pass between the atmosphere and the ground, and the internal material is intimate to block the block surface. No rain or air could pass through it.

Especially in rainy areas such as pedestrian paths, parks, plazas and cilantro sites, rainwater flows through the sewer pipes into the rivers, and the ground surface is increasingly dried up by the microbes that live in the ground, as well as by trees and grasses. Does not grow deep and shows unbalanced growth during growth.

In addition, during heavy rains, rainwater does not penetrate into the basement partly, but it is concentrated at the same time into the river, causing flooding. Due to the groundwater depletion, the soil is deserted, and thus it is impossible to maintain a natural ecosystem for a comfortable life. have.

In addition, on the sidewalk block, rainwater does not seep in rainy weather and stays on one side, hindering pedestrians' traffic.

Therefore, in recent years, some sidewalk blocks are provided with fine perforation holes on the upper surface, but the permeable block permeable to the ground itself is fine, so that the permeation holes are easily blocked by foreign matter such as dust or sand, and the perforation hole itself has the same height as the upper surface of the block. Has a problem that can not flow easily.

In addition, the strength of the sidewalk block is weakened due to such a perforation hole also causes problems such as breaking or breaking the sidewalk block.

Hereinafter, each embodiment of the pitcher block according to the present invention will be described in turn.

≪ Example 1 >

1 is a perspective view showing the configuration of a first embodiment of a water permeable block according to the present invention, Figure 2 is shown in a cross-sectional view of the configuration of a first embodiment of the present invention.

According to this, the permeable block according to the present invention is composed of a lower block portion 10 and the upper block portion 20. The lower block portion 10 is located below the upper block portion 20 relatively, the upper block portion 20 and the lower block portion 10 is formed of a different material.

More precisely, the lower block portion 10 has a relatively higher porosity than the upper block portion 20. This is to ensure the permeability by the lower block portion 10, the difference in porosity is represented by the difference in the material constituting the upper block portion 20 and the lower block portion 10.

The lower block portion 10 is made of a composition containing cement, aggregate and water (hereinafter referred to as 'first mixing body'), where cement is blast furnace slag cement and aggregate is made of single-grained crushed aggregate. desirable. This is because sufficient porosity can be ensured if the particle size of the aggregate is evenly distributed.

Of course, the permeability is determined not only by the porosity, but also by the size of the pores, the connectivity of the pores, the degree of bending of the passage, and thus, the crushed aggregate is preferably composed of single grain crushed aggregate having a particle size of 8 mm to 19 mm.

However, the lower block portion 10 secured with sufficient water permeability needs to compensate for this, because the durability and strength of the concrete are relatively weakened and the wear resistance is reduced by the voids, and this portion is the upper block portion ( 20).

Since the upper block portion 20 is manufactured by a composition including multi-particulate crushed aggregate (hereinafter referred to as 'second mixing body'), it has a relatively small porosity and high concrete durability and strength.

In addition, since the upper block portion 20 is a portion which is substantially exposed to the outside to form a road surface or sidewalk, such sufficient durability and strength may be required.

However, the upper block portion 20 has a relatively low porosity, so that the water permeability is reduced, which is solved by the water passage 50. The water passage 50 is formed between the upper block portion 20, the water passage 50 is a kind of channel formed between the upper block portion 20 as shown in FIG.

That is, the pitcher 50 corresponds to a space between the upper block portions 20 adjacent to each other, and is formed long along the longitudinal direction of the upper block portion 20. The pitcher 50 may include a spacer ( 40). Although not shown in FIG. 1, the spacer 40 has a rectangular frame shape that is opened in the vertical direction, and is installed between the upper block portions 20 to secure the water passage 50. The spacer 40 may be removed after the upper block portion 20 is cured.

At this time, as shown in Figure 2, the upper block portion 20 is preferably formed of a relatively smaller thickness than the lower block portion (10). This is to ensure that the permeability of the entire permeable block is secured to a predetermined level or more.

2 schematically illustrates a process of water permeation by the water permeable block. The water on the surface of the upper block portion 20 is first transferred to the lower portion through the water permeable passage 50, and then to the lower block portion 10. The arrived moisture is permeated downward through the air gap of the lower block portion (10).

Next, a process of manufacturing the first embodiment of the permeable block according to the present invention will be described.

3 is a working state diagram showing a process for manufacturing a first embodiment of a water permeable block according to the present invention.

As shown in the drawing, first, the first mixing body is injected into the mold 100. In addition, the first mixing body injected into the mold 100 is compacted and cured. In this process, the upper portion of the lower block part 10 may be increased by vibrating the upper portion of the first mixing body at a constant pressure. have.

More specifically, the first mixing body is first vibrated, and then the first mixing body can be sufficiently compacted by pressing with a pressure plate. The vibration process uses a motor or the like.

Next, a spacer 40 (interval) is provided above the first mixing body. The spacer 40 is for securing the water passage 50, and in this embodiment, a total of two spacers 40 are installed in an elongated rectangular frame having a drainage space therein.

In this state, the second mixing body is injected above the lower block part 10 generated by the first mixing body. In this process, the second mixing body is naturally divided into three parts by the spacer 40.

The second mixing body is also compacted and cured in the same manner as the above-described process, and in this process, vibration and pressure may be applied by the pressure plate.

Although not shown, the process of generating the lower block portion 10 and the upper block portion 20 may be generated by a vibration compression molding machine.

And when the second mixing body is also completely cured, it is finally completed by removing the mold 100. Additionally, the spacer 40 may also be removed, but the spacer 40 may be used without being removed.

The water permeable pipe 40 is for flowing water that collects on the upper surface of the upper block portion 20 downward, and is a kind of tubular shape that is opened in the vertical direction. That is, the pitcher tube 40 forms a pitcher passage 50 to communicate the upper block portion 20 and the lower block portion 10.

The water permeable pipe 40 is intermittently formed in the upper block portion 20. This is to ensure sufficient water permeability by the water pipe 40, in this embodiment, a total of six water pipes 40 are installed in the upper block portion 20, but is not necessarily limited to this 7 The above may be installed.

FIG. 5 schematically illustrates a process of water permeation by the water permeation block. The water on the surface of the upper block portion 20 is first transmitted to the lower portion through the water passage 50 formed by the water permeation pipe 40. The moisture arriving at the lower block portion 10 is permeated downward through the gap of the lower block portion 10.

Next, a process of manufacturing the second embodiment of the permeable block according to the present invention will be described.

6 is a working state diagram showing a process for manufacturing a second embodiment of a water permeable block according to the present invention.

Next, the water supply pipe 40 is installed above the first mixing body. The water permeable pipe 40 is for securing the water passage 50, and in this embodiment, a total of six tubular water permeable pipes 40 are installed.

In this state, the second mixing body is injected above the lower block part 10 generated by the first mixing body. In this process, the space in which the water pipe 40 is installed remains naturally and only the remaining portion is filled by the second mixing body.

The second mixing body is also compacted and cured in the same manner as the above-described process, and in this process, vibration and pressure may be applied by the pressure plate.

Although not shown, the process of generating the lower block portion 10 and the upper block portion 20 may be generated by a vibration compression molding machine.

And when the second mixing body is also completely cured, it is finally completed by removing the mold 100. In addition, although the permeable pipe 40 may also be removed, the permeable pipe 40 may be used without being removed.

This is to allow the pitcher passage S to be formed between the unit blocks 200. As shown in FIG. 7, the pitcher passage S is formed to be long between the unit blocks 200.

At this time, the unit block 200 is connected by the coupling unit 400. The coupling unit 400 not only connects the unit blocks 200, but also arbitrarily adjusts the interval between the unit blocks 200.

Specifically, the coupling unit 400 is screwed to the outer surface of the base body 410 and the base body 410, the both ends of which are respectively inserted into the coupling hole 210 of the unit block 200 adjacent to each other It is configured to include a pair of distance adjuster (450,460).

As shown in FIG. 8, the pair of unit blocks 200 are coupled by a total of three coupling units 400, and the number and position of the coupling units 400 may be changed.

On the other hand, the unit block 200 is made of a material having a high performance (實 積 率), because the fluid does not need to be discharged through the unit block 200 itself. Accordingly, the durability and strength of each of the unit blocks 200 is sufficiently large, and has a large wear resistance.

The lower block portion 100 is located below the upper block portion 200 relatively, the upper block portion 200 and the lower block portion 100 is formed of different materials.

More precisely, the lower block portion 100 has a relatively high porosity than the upper block portion 200. This is to ensure the permeability by the lower block portion 100, the difference in porosity is represented by the difference in the material constituting the upper block portion 200 and the lower block portion 100.

The lower block portion 100 is made of a composition containing cement, aggregate and water (hereinafter referred to as 'first mixing body'), wherein the cement is blast furnace slag cement and the aggregate is made of single grain crushed aggregate desirable. This is because sufficient porosity can be ensured if the particle size of the aggregate is evenly distributed.

Of course, the permeability is determined not only by the porosity, but also by the size of the pores, the connectivity of the pores, the degree of bending of the passage, and thus, the crushed aggregate is preferably composed of single grain crushed aggregate having a particle size of 8 mm to 19 mm.

However, the lower block portion 100 secured with sufficient permeability has a need to compensate for this, because the durability and strength of the concrete are relatively weakened and the wear resistance is reduced by the voids, and this portion is the upper block portion ( 200).

Since the upper block portion 200 is manufactured by a composition including multi-particulate crushed aggregate (hereinafter referred to as a 'second mixing body'), it has a relatively small porosity and a large concrete durability and strength.

In addition, since the upper block portion 200 is a portion that is substantially exposed to the outside to form a road surface or sidewalk, such sufficient durability and strength may be required.

The unit block I composed of the upper block part 200 and the lower block part 100 is connected to each other to form a permeable block.

At this time, the unit blocks (I) are connected by the coupling unit (400). The coupling unit 400 not only connects the unit blocks I, but also arbitrarily adjusts the interval between the unit blocks I.

This is to ensure better permeability by allowing the lower block portion 100 to be spaced apart using the coupling unit 400 when higher permeability is required at the place where the permeable block is installed.

Specifically, as shown in FIG. 10, the coupling unit 400 includes a base body 410 having both ends thereof inserted into coupling holes 210 of unit blocks I adjacent to each other, and the base body 410. It is configured to include a pair of distance adjusting portion 450,460 screwed to the outer surface.

In addition, the pair of distance adjusting units 450 and 460 may adjust the distance between the unit blocks I by adjusting the distance between the two through rotation on the base body 410. Reference numeral 420 denotes a thread.

As shown in Figure 10, the pair of unit blocks (I) is coupled by a total of three coupling units 400, the number and position of the coupling unit 400 may be changed.

At this time, as shown in Figure 10, the upper block portion 200 is preferably formed of a relatively smaller thickness than the lower block portion (100). This is to ensure that the permeability of the entire permeable block is secured to a predetermined level or more.

Looking at the process of the fluid is permeated by the water permeable block, the water on the surface of the upper block portion 200 is first transmitted to the lower through the water passage (S) formed between the upper block portion 200, the lower Moisture that has arrived in the block portion 100 is permeated downward through the gap of the lower block portion 100.

Next, a process of manufacturing the fourth embodiment of the permeable block according to the present invention will be described.

First, the first mixing body is injected into the mold. In addition, the first mixing body injected into the molding die is compacted and cured, and in this process, the strength of the lower block part 100 may be increased by vibrating the upper portion of the first mixing body at a constant pressure.

More specifically, the first mixing body is first vibrated, and then the first mixing body can be sufficiently compacted by pressing with a pressure plate. The vibration process uses a motor or the like.

In this state, the second mixing body is injected above the lower block part 100 generated by the first mixing body. The second mixing body is also compacted and cured in the same manner as the above-described process, and in this process, vibration and pressure may be applied by the pressure plate.

Although not shown, the process of generating the lower block portion 100 and the upper block portion 200 may be generated by a vibration compression molding machine.

When the second mixing body is also completely cured, the molding frame is finally removed to complete one unit block (I).

Finally, the unit block I is connected again by using the coupling unit 400 to complete the permeation block. At this time, the interval between the pitcher block may be adjusted through the distance adjusting unit 450, 460 of the coupling unit 400.
