Drainage system using fresh water block {DRAINAGE SYSTEM USING WATER STORAGE BLOCK}

The present invention relates to a drainage system using a freshwater block, and more particularly, a plurality of freshwater blocks are stacked on slopes of a river or dam embankment or road surface so that rainwater rainwater flows into the freshwater block. It relates to a drainage system using a freshwater block that can prevent the collapse of the slope due to the earth and sand by preventing a large amount of rainwater flowing along the slope by sequentially passing through the freshwater block of the drain to the river or dam.

In general, slopes on both sides of the road and embankments and lakes of dams or rivers form slopes with a constant stability angle to prevent the collapse of sediment and overflow of dams or river water.

Although the slope is formed at a stable angle, when a large amount of water penetrates during heavy rains, the compaction force of the slope decreases, causing the soil to be swept out and collapsed, and the greater the amount of rainwater flowing along the slope, the proportion of erosion. There is a disadvantage that grows.

Therefore, in recent years, the slope is prevented from heavy rain by forming a gabion or a concrete block and forming vegetation on the upper portion of the slope, instead of only the soil. However, even in this case, there is a risk that the collapse of the vegetation loss and the upper banks may occur due to the large amount of rainwater flowing down the slope because the rainwater is larger than the drainage through the ground.

In addition, in case of the concrete block, the rainwater discharged to the installation surface is blocked, so a large amount of rainwater generated during heavy rains is flooded due to flooding due to the inflow into the river as the portion is supplied to the river or the dam through the slope. And flooding damage.

Recently, a method of forming slopes into vegetation blocks to absorb some of the rainwater by itself and blocking the collapse of slopes, but in case of heavy rains, the vegetation is damaged by a large amount of rainwater flowing along the slope. Or because of the loss of vegetation soil there is a hassle to repair frequently. In particular, recently, since the upper surface of the embankment is used as a road, all rainwater falling to the upper surface of the embankment is drained through the slopes, so a large amount of slope soil loss is caused by a large amount of storm drainage.

Therefore, it is necessary to study a method of saving and recycling part of rainwater as well as slope rainwater by reducing rainwater flowing along slopes at the upper part of rivers or dams during heavy rains.

The drainage system using the slope freshwater block in the present invention,

A freshwater block with a hollow portion formed inside and inlet and outlet holes respectively formed on the upper and lower portions of the freshwater block is formed on a slope of a river or a dam and a road surface of a road so that rainwater generated during heavy rain does not flow to the slope. It is intended to prevent the loss of slope by draining through.

In another aspect, the present invention is to provide a water storage system to form a collection tank at the bottom of the fresh water block to be stored to store the rainwater passing through the fresh water block in a separate storage tank for use as agricultural water or industrial water.

The drainage system using the freshwater block of the present invention for solving the above problems,

A large number of freshwater blocks formed on the slopes of river banks or road slopes are formed of a main body having a receiving space formed therein and a discharge hole for discharging the rainwater introduced therein, and a plurality of rainwater inlet holes formed with a cover covering the upper part of the main body. To form a freshwater block layer,
The freshwater block 20 is arranged to retreat the upper freshwater block to a predetermined length from the river or road than the lower freshwater block so that a part of the inflow hole of the upper surface of the inner freshwater block which is formed in the direction of the river or the road is exposed, and the inner freshwater block A discharge formed at the bottom of the outer freshwater block, which is masonry to be pushed outward of a river or road so that a portion of the lower portion thereof is supported by a portion of the inner masonry block so as to expose a portion of the inlet hole at the top of the inner freshwater block. The ball is in contact with the ground and closed,
Rainwater is introduced into the inner receiving space on the upper surface of the plural freshwater blocks, and rainwater flowing into the receiving space is lowered along the inside of the freshwater block and discharged from the bottom to the side.
The freshwater blocks may be manufactured by mixing at least one of industrial by-products including blast furnace slag and fly ash, thereby reducing waste of recycling as well as manufacturing cost.

In addition, at the bottom of the assembled freshwater block layer to form a collection tank to collect the rainwater discharged from the freshwater block, the collection tank communicates with the storage tank by a drain pipe so that the collected rainwater is stored, the storage tank is pumped Rainwater stored by can be pulled upwards to be used.

The drainage system using the freshwater block of the present invention by the above solution,

By installing fresh water blocks on the slopes of dams or rivers, the rainwater generated on the upper surface of dams or river banks is introduced during heavy rains and drained along the internal flow path to discharge into rivers. It can flow to the slope of the back to prevent the soil of the slope from being lost or collapsed.

In addition, by controlling the cross-sectional area of the inlet and outlet holes in the freshwater block, the rainwater discharged through the rainwater is delayed so that the rainwater can be adjusted to the dam or the river during heavy rains. By storing it as a reservoir, it is possible to provide a useful system that can help in case of drought.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the appended drawings illustrate only the contents and scope of technology of the present invention, and the technical scope of the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples.

1 is a schematic view showing a drainage system using a freshwater block according to an embodiment of the present invention, Figure 2 is a perspective view showing a freshwater block according to an embodiment of the present invention.

As described, the drainage system 10 according to the present invention is made by bundling a plurality of fresh water blocks 20.

The fresh water block 20 is composed of a main body 22 formed in the receiving space 221 therein, and a cover 21 covering the upper portion of the main body. The main body is a rectangular cylinder with an upper opening and a plurality of discharge holes 222 are formed on the lower surface to discharge rainwater introduced into the accommodation space.

The cover 21 covering the opened upper surface of the main body is formed with a plurality of inlet holes 211 to allow rainwater to flow from the outside. The inlet hole may be formed in a plurality on the entire surface of the cover to facilitate the inflow of rainwater, it may be configured as a permeable material without the inlet hole, although not shown.

In addition, the inlet hole 211 and the outlet hole 222 is formed in each of two rows in the longitudinal direction as shown in the form of six each of six and the upper and lower inlet and outlet holes are located on the same axis with each other, or The cover may be formed into a porous plate, and a plurality of discharge holes may be formed, and various methods for introducing and discharging rainwater may be applied.

The combination of the main body 22 and the cover 21 may form a step along the edge of the bottom of the cover, and the bottom protruding by the step may be embedded in the receiving space of the main body. In addition, the main body 22 may partition the space by forming one or a plurality of vertical bulkheads in the accommodation space. This increases the structural strength by the vertical bulkhead can prevent the freshwater block from being damaged by earth pressure and compaction force.

In addition, as shown in FIG. 3, the storage space 221 may further include a plastic reservoir 23 having the same or similar size as the accommodation space. That is, when the freshwater block is formed of concrete material, the plastic storage tank 23 is embedded in the receiving space 221 to prevent breakage due to repeated exposure to rainwater and to minimize the discharge of lime extract water by rainwater. The rainwater introduced can be stored in a plastic reservoir. The plastic storage tank has a discharge hole is formed on the same axis as the discharge hole of the main body so that the discharge of the rainwater is introduced.

Here, the total cross-sectional area of the discharge hole 222 formed in the main body or the plastic storage tank is made smaller than the overall cross-sectional area of the inlet hole 211 of the cover 21 so that the rainwater that is introduced is delayed in the receiving space for a predetermined time and then discharged. Can be. In this way, by adjusting the cross-sectional area of the inlet and outlet holes, the rainwater flowing into the freshwater block can be delayed for a certain period of time during heavy rains, thereby preventing a large amount of rainwater from entering the river or dam at once, thereby minimizing damage caused by flooding. have.

The freshwater block 20 configured as described above may be assembled to an inner slope of a river or a dam or a normal surface of an incision road as shown in FIG. 1. The freshwater block may be vertically aligned in one row or vertically in one row with a predetermined width. At this time, the lowermost end of the assembled freshwater block layer may be located above the river or the dam water level to prevent the flowing water or freshwater from flowing in.

As a method of bundling the freshwater block 20, a first stage freshwater block is installed horizontally at the bottom end, and a second stage freshwater block is installed on the upper side so that a predetermined length is retracted in a river or road direction. Freshwater blocks can be installed at an angle.

Here, the upper and lower freshwater blocks may be installed so that the discharge hole and the inlet hole are located on the same axis, and in order to facilitate the installation, the discharge hole may protrude from the bottom of the freshwater block body so that the freshwater block may be inserted into the other freshwater block inlet hole at the bottom thereof. Can be formed.

The freshwater block thus assembled is the upper surface of the inner freshwater block in the direction of the river or the road among the freshwater blocks of the interlayer formed, the inflow hole is exposed to the outside, the bottom of the outer freshwater block is closed by the discharge hole in contact with the ground. The closure can be artificially closed by blocking the discharge hole during installation. That is, all the inflow holes are exposed at the top of the freshwater block layer so that the rainwater from the top of the slope is maximized, and the middle part of the freshwater block layer is exposed to some inflow holes so that some of the small rainwater flowing along the slope is introduced into the interior. Can be.

Therefore, the rainwater flowing into the upper and the slopes of the slope flows into the freshwater block and moves along the flow path inside the freshwater block, so that a large amount of rainwater flows on the slope to prevent soil leakage or slope collapse.

In addition, all of the inlet holes in the freshwater block are open to allow the inflow of rainwater from the outside, but since some of the discharge holes are closed, the discharge of the inflow rainwater may be delayed and discharged for a predetermined time.

In addition, the bottom of the assembled freshwater block layer is a drain block 30 for discharging rainwater flowing through the freshwater block to the edge drainage of the river or dam or road. As shown in FIG. 4, the drainage block 30 has a drainage passage 31 formed therein, and the drainage passage is formed laterally from an upper surface of the drainage block. That is, the inlet of the drain passage 31 of the upper surface of the drain block communicates with the discharge hole 222 of the fresh water block 20 placed on the drain block to receive rainwater discharged from the discharge hole. As it moves along the drainage channel, it is discharged in the direction of the stream, dam or road through the side of the drainage block.

In addition, as shown in Figure 5, the rainwater storage means 40 may be further installed at the lower end of the assembled fresh water block layer. The rainwater storage means 40 is a storage tank 43 for collecting rainwater discharged into the discharge hole of the freshwater block 20 and a rainwater tank 43 for receiving and storing rainwater collected in the collecting tank through a flow passage pipe 42. It can be used to pump and use the stored rainwater during the dry season.

The collection tank 41 is formed in a mesh form so that the freshwater block can be formed in the upper portion or a plurality of vertical bulkheads formed therein to support the freshwater block to be supported, such as to support the freshwater block, various forms of receiving rainwater It can be formed as.

In addition, the storage tank 43 is connected to the flow pipe from the collection tank to receive the rainwater collected in the collection tank to connect a plurality of rainwater storage tanks generally used in parallel to store a large amount of rain, or a separate storage space Various storage means can be applied.

Rainwater storage means (40) consisting of a collection tank and a storage tank for utilizing the rainwater is installed only in a portion of the entire length of the embankment to recycle rainwater, the section is not installed rainwater storage means in the drainage block (30) It is desirable to allow drainage by.

As described above, the freshwater block 20 forms a slope, and the drainage system 10 having the drainage block 30 or the rainwater storage means 40 at the bottom thereof is a freshwater block having rainwater falling on the upper bank and the slope. By flowing into the freshwater block through the inlet hole 211 of 20, the amount of rainwater flowing to the slope can be drastically reduced to prevent drainage and slope collapse, and drainage of rainwater can be achieved.

In addition, when the rainwater storage means 40 consisting of the collecting tank 41 and the storage tank 43 is installed in the lower portion of the fresh water block is collected and stored to collect the rainwater that is moved into the freshwater block is discharged to the river or dam It is effective to prevent flood damage caused by river flood by reducing the amount of rainwater, and the stored rainwater can be pumped by a pump if necessary, so that natural energy can be recycled such as used for agricultural water or industrial water during the dry season. have.

In addition, the freshwater block may be manufactured by simple cement curing, but by mixing industrial by-products such as blast furnace slag fly ash, the waste may be recycled and manufacturing costs may be reduced.
