Description

Groundwater drainage system using drain belt {Apparatus for Channeling Groundwater using Drain belt}

The present invention relates to groundwater drainage, and more particularly to groundwater drainage using a drain belt to improve drainage capacity and workability.

In general, water has been moving for hundreds of millions of years without the need for artificial devices such as pipes and filters under the ground. The main source of groundwater is rainwater. Rainwater that has fallen to the ground seeps into the ground along soil and rock gaps, creating a perfect balance between each other's supply and demand functions.

Recently, natural damage caused by artificial activities such as construction, logging and mine development, and golf course construction has hindered the natural circulation of water. Accordingly, pipes are designed for the purpose of transporting water or other liquids.

Therefore, as long as the slope is adequate, the pipe can easily move water to a given place. Water drains are generally designed as closed drains so that they are not blocked by other particles.

For example, in the case of a golf course site, it is necessary to be able to quickly drain the groundwater to the ground except for the amount required for plant growth. The drainage facility, which is constructed for this purpose, is constructed so that surface water that penetrates into the soil through the grooves can be drained into the drainage pipe through the grooves having a large or small hole or slot shape having a predetermined size on the outer circumferential surface of the pipe type pipe. .

However, conventionally, when the groove is installed on the outer circumferential surface of the drain pipe, the soil particles (dirt) have penetrated into the pipe together with the water. Some soil particles are discharged through the drainage pipe together with the water, but the slope of the drainage pipe is gentle and the water flow is weak, so that the water sinks to the bottom and eventually blocks the entire drainage pipe.

In addition, when a small hole is drilled in the drain pipe to solve this, it is possible to prevent the inflow of soil particles into the drain pipe, but the hole is easily clogged, which resulted in not being helpful for drainage.

Drain rubble, sand, nonwoven fabrics have been used to prevent soil particles from settling in and out of drain pipes.

However, since rubble only acts to sink before the fine particles enter the drainage system, these sediments vary in particle size, drainage, and space area, and eventually accumulate in soil particles. Sand also plays a role similar to rubble, but the problem is mixed with small soil particles, which in itself is a problem.

In addition, the method of auditing the outer circumferential surface of the nonwoven fabric is also encouraged to be clogged by the small particles, so that as the time passes after the construction work, the drainage performance is significantly lowered, and sufficient drainage cannot be achieved. Was implicated.

Therefore, when water and particles flow in the same direction, water contains and flows microparticles, which has become a major factor in the flow of water when these particles precipitate and block the filter.

The present invention is to solve the above problems to improve the work efficiency by making the connection socket for connecting the drain pipe and the drain pipe to have a certain gap in the form of separation and inserting the drain belt between the connection socket and fixing with bolt nut fastening and In addition, the object of the present invention is to provide a groundwater drainage system using a drain belt that reduces maintenance costs and improves the groundwater drainage capacity.

The groundwater drainage apparatus using the drain belt according to the present invention for achieving the above object has a constant gap between the first drain pipe and the second drain pipe formed with a hollow pipe, and the first drain pipe and the second drain pipe have a constant gap. Connection sockets connecting the first and second drain pipes to each other to have a connection socket, the connection socket has a first and second bending plate and the coupling hole is formed at regular intervals on both sides of the corresponding band with a constant distance from each other; It consists of a fastening bolt for penetrating the first and second bent plate, and inserted and fixed between the first and second bent plate of the connecting socket in a direction perpendicular to the first and second drain pipe, the first drain pipe And a drain belt extending to a gap portion between the second drain pipes.

Groundwater drainage using the drain belt according to the present invention has the following effects.

In other words, by making the connecting socket connecting the drain pipe and the drain pipe with a certain gap in a separate form, inserting the drain belt between the connecting socket and fixing it with bolt nut tightening to improve work efficiency and reduce maintenance costs and drainage capacity Can improve.

In the groundwater drainage apparatus using the drain belt according to the present invention, when installed to form a slope or at least 2% or more inclined slope in the soil, a plurality of slit grooves are formed on the outer circumferential surface of the plate 141 in the number of gaps contained in the soil. A plurality of drain pipes 110 and 120 that flow into the drain hole 142 and rise to the ground surface due to capillary action as the number of gaps stored in the drain hole 142 increase due to 143. Drain through.

In the drain belt 140 installed inside the ground as described above, when the gap water contained in the soil is discharged to the ground, strong earth pressure is applied to both sides of the drain belt 140, and the strong earth pressure generated at this time is the drain belt 140. Even if it is applied to both sides of the inner drain hole 142 is to prevent the depression is to maintain the original state.

Then, the earth is buried in the drain belt 140 and the drain pipes 110 and 120, which are fixed with the fastening bolts 134, to finish adjusting the flat surface.

Therefore, the present invention can be constructed very economically because the excavation cost is low, no gravel, sand, non-woven fabric, no maintenance costs, no need to replace.

In addition, the present invention is formed by integrally forming a plurality of slit grooves 143 communicating with the drain holes 110 and 120 in the drain belt 140, so that the drain hole is not easily recessed and maintains its original state as much as possible after the construction work. The drainage effect can be maintained permanently because it is not blocked and absorbs more than 20% of the unit surface area and the total length. Therefore, the large drainage area and the thin and flexible drain belt can be applied to any drainage map because it is easily applied along the surface irregularities. .

In addition, even if heavy equipment passes the site where the groundwater drainage device of the present invention is constructed, it does not require any reinforcement work, and the capillary phenomenon, the surface tension, and the siphon phenomenon are harmonized to obtain the maximum drainage efficiency, and the radius is around 1M. The water can also be absorbed and drained smoothly.

On the other hand, the present invention described above is not limited to the above-described embodiment and the accompanying drawings, it is possible that various substitutions, modifications and changes within the scope without departing from the technical spirit of the present invention It will be apparent to those skilled in the art.
