The present invention relates to a vertical drainage and a management method that can reduce the clogging phenomenon of the filter by generating an ultrasonic wave, and more particularly, by providing an ultrasonic vibrator in the vertical drainage and fine particles attached to the filter by the ultrasonic wave generated from the ultrasonic vibrator The present invention relates to a vertical drainage and management method using ultrasonic waves, which can achieve a smooth drainage effect by preventing clogging caused by the blockage.

In order to create roads, industrial complexes, and residential complexes, soft grounds with high water content, such as coastal or lake landfills, are strengthened.

As soft ground has high fluidity and large amount of consolidation settlement, the vertical drainage method is used as a dewatering method to increase the bearing capacity and reduce settlement of ground by causing consolidation settlement in advance.

In the PCD (Plastic Cylindrical Drain) method, which is one of the vertical drainage methods, as a vertical drainage material for draining the gap water in the soft ground, a hollow core pipe made of a cylindrical core and a filter surrounding the same is used. Due to the excess pore water pressure of the ground, the ground pore water is discharged to the ground through the drainage pipe of the perforated pipe, so that the ground is consolidated and the ground is strengthened as the bearing capacity of the soft ground increases as time passes.

However, there is a problem in that drainage performance is reduced while clogging occurs due to clogging due to fine particles sticking to the filter, thereby blocking a hole formed radially in the cylindrical core.

In addition, the above-described conventional perforated pipe has a problem in that the pore water drainage efficiency to the ground is low because the ground pore water flows only through the radial hole formed in the cylindrical core.

Accordingly, the present invention is to solve the above problems, the object of the present invention is to provide an ultrasonic vibrator in the vertical drainage to prevent the clogging phenomenon caused by the fine particles stuck to the filter by the ultrasonic wave generated in the ultrasonic vibrator. It is to provide a vertical drainage and management method using ultrasonic waves to achieve a drainage effect.

In addition, the present invention provides a vertical drainage and management method using ultrasonic waves that can quickly remove the filter clogging by adjusting the appropriate frequency and vibration width in the control box according to the ground conditions.

In addition, the core is a coil spring-type core wound in a spiral, the flow passage is characterized in that formed by the gap between the coil and the coil adjacent to the coil spring-type core.

In addition, the core is a ring-shaped core consisting of a plurality of rings at a predetermined interval in the longitudinal direction, the flow passage is characterized in that formed by the gap between the ring and the ring adjacent to the ring-shaped core.

The technical features of the present invention include an ultrasonic vibrator generating ultrasonic waves to be separated and removed, and a control box for transmitting a signal of oscillating and amplifying a frequency through a connecting line to the ultrasonic vibrator.

1 is a view showing the installation state of the vertical drainage using ultrasonic waves according to the present invention.

As shown in FIG. 1, a plurality of vertical drainers 10 using ultrasonic waves according to the present invention are installed in the ground of the soft ground 100, and an ultrasonic vibrator (6) is formed inside the plurality of vertical drainers 10. 20) and the control box 21 is installed on the ground surface, the control box 21 sends a signal oscillating and amplified frequency through the connecting line 22 to the ultrasonic vibrator 20. Then, ultrasonic waves are generated in the ultrasonic vibrator 20 to separate and remove the fine particles attached to the filter.

2 is a cross-sectional view showing a state in which an ultrasonic vibrator is installed in a vertical drainage material made of a known spiral corrugated core as a first embodiment of the present invention.

The vertical drainage material 10 constituted in the first embodiment of the present invention is a product widely used in the vertical drainage method. As shown in FIG. 2, a drainage passage 14 is formed, and the drainage passage 14 and It is composed of a spiral pleated core (11a) formed with communicating holes 13a and a filter 12 surrounding the outer periphery of the helical pleated core (11a), the ultrasonic vibrator 20 inside the helical pleated core (11a) Is installed.

The ultrasonic vibrator 20 is mounted to the front end of the connection line 22 connected to the control box 21.

The ultrasonic vibrator 21 may be located inside the drain 14, and although not shown in the drawing, the ultrasonic vibrator 20 may be attached to an outer surface of the filter 12, and the spiral pleated core It can also be attached to the inner side of (11a).

On the other hand, the connecting line 22 is preferably formed by introducing the electric wire cable inside the flexible pipe (flexible pipe) so that it can be bent freely. The reason is that when the vertical drainage 10 is installed in the ground is not a vertical state is bent and deformed, or if the deformed by the dehydration and embankment load of the soft ground is bent and deformed, the ultrasonic vibrator ( This is to facilitate the operation of putting 20 into the curved drainage 14.

In more detail, in the vertical drainage management method using ultrasonic waves according to the present invention, the core 11 and the core 11 is formed with a drain passage 14 is formed and the flow passage 13 is in communication with the drain passage 14 In the state in which the vertical drainage 10 made of the filter 12 surrounding the outer circumference of the shell is placed on the soft ground, the flexible tube in which the ultrasonic vibrator 21 is connected to the distal end and the wire cable is inserted into the drainage passage 13 In this case, when the vertical drainage material is bent deformation, the flexible pipe may be inserted along the curved drainage passage 14, and the ultrasonic wave may be inserted into the filter 12 by generating ultrasonic waves for a predetermined period of time. After the particles are separated and removed, the connecting line 22 can be easily taken out along the curvature of the drainage channel by the flexible tube even when the connecting line 22 is pulled out of the drainage channel 14.

3 is a perspective view showing a state in which an ultrasonic vibrator is installed in a vertical drainage material consisting of a coil spring type core as a second embodiment of the present invention, and FIG. 4 is a coil spring type core applied in the second embodiment of the present invention. 5 is a cross-sectional view of a vertical drainage made of a ring-shaped core to which the present invention is applied, as a third embodiment of the present invention.

The vertical drainage material 10 consisting of the coil spring type core 11b and the ring type core 11c shown in FIGS. 3 to 5 is a vertical drainage material newly developed by the present applicant.

As shown in FIG. 3, the vertical drainage material 10 applied in the second embodiment of the present invention is composed of a coil spring-type core 11b wound in a spiral shape, and is disposed between the coil 15 and the coil 15 that are adjacent to each other. The flow passage 13b is formed on the entire outer circumference by the interval of.

In this way, the drainage passage 14 is formed in the longitudinal direction inside the coil spring type core 11b wrapped with the filter 12.

Since the flow passage 13b is formed at every interval between the coil 15 and the coil 15, the gap number of the soft ground can flow through the entire surface of the filter 12 from all directions, that is, the flow passage 13b. Is secured to the maximum and smooth discharge of the pore water is achieved, so that the drainage efficiency is increased and the ground strengthening effect can be obtained quickly.

Here, in the case of the vertical drainage material consisting of the spiral pleated core (11a), the ultrasonic wave of the ultrasonic vibrator 20 will only touch the portion of the filter 12 in the hole 13a position, but generated in the ultrasonic vibrator 20 Ultrasonic waves that are touched over the entire surface of the filter 12 through the water flow passage 13b may also provide an effect of separating and removing fine particles attached to the entire surface of the filter in a short time.

In the vertical drainage material 10 formed of the ring-shaped core 11c shown in FIG. 5, a plurality of rings 16 are formed at regular intervals in the longitudinal direction, and the distance between the adjacent ring 16 and the ring 16 is adjacent. By this, the flow passage 13b is formed, and the same effect as the flow passage 13b formed in the coil spring core 11b can be obtained.

2, 4 and 5, reference numeral P, which is not explained in the drawings, refers to a 'heat-sealed portion', and a joint portion in which the filter 12 is heat-sealed around the outer circumference of the cores 11a, 11b, and 11c. It is displayed.

In the case of installing the vertical drainage very deep in the ground of the soft ground, that is, in the case of placing in the depth of the depth by connecting a plurality of ultrasonic vibrators 20 to the connecting line 22 at a certain distance from the tip of the connecting line 22, drainage (14) The effect of the ultrasonic wave on the entire interior space can cause the fine particles adhering to the entire surface of the filter 12 through the flow passages 13b to be separated and removed at once.

Hereinafter, the process of separating and removing the fine particles attached to the filter 12 by the ultrasonic waves generated by the ultrasonic vibrator 20 will be described.

First, a signal obtained by oscillating and amplifying the frequency of ultrasonic waves in the control box 21 is sent to the ultrasonic vibrator 20 through the connecting line 22. Accordingly, ultrasonic waves are generated in the ultrasonic vibrator 20 installed in the drainage passage 14, and water molecules in the drainage passage 14 vibrate. As a result, shock waves are generated and the filter 12 passes through the water flow passage 13b. By hitting the inner surface of the), the fine particles adhering to the filter 12 is dropped.

More specifically, when the ultrasonic wave itself repeats the vibration of tens of thousands of times, the phenomenon of pushing and pulling water molecules on the surface of the filter 12 repeatedly occurs. Then, the cohesive force of the water molecules is destroyed, and numerous fine cavities are generated. At this time, numerous bubbles are generated by the cavitation between the water and the fine particles attached to the filter 12, and the water molecules are accelerated to the surface of the filter 12. It will be to separate and remove the fine particles stuck to the filter 12 by the impact force.

In this way, the clogging phenomenon of the filter 12 can be removed by the ultrasonic waves in a very short time, and the drainage function of the vertical drainage material can be prevented from being degraded due to the fine particles attached to the filter 12 by periodically generating the ultrasonic waves. That is, it is possible to smoothly drain the excess pore water of the soft ground to the ground through the drainage path (14).

On the other hand, depending on the ground conditions may occur if the fine particles stuck to the filter 12 is not falling well, in this case, the control box 21 can adjust the ultrasonic frequency and vibration width.

When the frequency is increased by the control of the control box 21, the size of the bubbles becomes fine, the acceleration of the water molecules is increased in proportion to 2 times, the wavelength is also reduced, and the penetration force is increased, so that very fine particles can be removed.
