Description

A WRINKLE DRAIN FOR FILTERING TO QUICKEN DEHYDRATION OF TENDER BASE WITHOUT THE NON-WOVEN CLOTH ATTACHED AND THE GOODS}

The present invention is formed in the structure of the drainage gap in the periphery of the inlet ring to form a corrugated drainage pipe in order to more effectively deodorize the water (moisture) contained in the soft ground composed of viscous soil such as coast, riverside, bog, swamp The present invention relates to a filtration drainage pipe for dewatering soft ground without nonwoven fabric.

Conventionally, a method for promoting dehydration of a viscous soil soft ground using a pleated drainage pipe for filtration to dehydrate water contained in the soft ground has been proposed in Korean Patent Publication (Publication No. 96-3745).

In the structure of the pleated vertical drainage pipe for filtration proposed to dehydrate water (moisture) contained in the conventional soft clay soft ground, several drainage holes are drilled at the periphery of the concave ring forming the corrugated tube. , Since a separate nonwoven fabric is coated on the periphery of the corrugated pipe, manufacturing and construction work are cumbersome, so manufacturing cost and construction cost are high, and when the soft ground is settled, the nonwoven fabric is torn, and the side pressure is high during use. In this case, the nonwoven fabric is depressed and the water permeability is reduced, so the function of the nonwoven fabric is not smooth, and the absorption and dehydration of water is deteriorated. There was a defect that the blockage can not be dehydrated.

The present invention is formed in the periphery of the pleat drainage pipe for filtration to eliminate the drawbacks of the prior art by forming a drainage gap of the micro-gap circumference of the pleat drainage pipe at the time of installation and use as a structure without a separate non-woven fabric Even if the lateral pressure of the soft ground increases, the water contained in the soft ground flows smoothly into the pleated drainage pipe without deforming or clogging the drainage so that the dehydration effect can be enhanced. The purpose is to reduce the production cost by completing the production by a simple operation to form only the drainage gap without the need for a separate non-woven fabric.

In the conventional corrugated drainage pipe (1) in which the concave wheels (3) and the protruding wheels (4) are formed continuously to form the internal conveying path (2), the microcircular structure is formed at the periphery of each concave ring (3). Several drainage gaps 5 were formed.

The drainage gap 5 is formed so as to smoothly introduce the water 7 contained in the soft ground 6. It is preferable to form the structure of the "type drainage gap 5a. Moreover, the structure of the drainage gap 5 of this invention is shown in FIG. 2 and FIG. 3 as a 1st Example and a 2nd Example of this invention. As " "The structure of the mold | type drainage gap 5b" It formed in the structure of "type | mold drainage gap 5c.

In the present invention as described above, the blade is formed by a punching device portion (not shown) separately provided at the periphery of the concave ring ring 3 of the corrugated drain pipe 1 in a state in which the concave wheel 3 and the protruding wheel 4 are continuously formed. The part is cut to form a drainage gap 5 of the microgap structure at the periphery of the concave ring 3.

At this time, the structure of the drilling device to form a fine gap by cutting by the blade portion is installed in the ring-shaped structure on the periphery of the concave wheel (3), the structure of the blade tip portion of the present invention and the first and second embodiments As shown in the example, "Type drainage gap 5a" "Type drainage gap 5b and" "The structure of each drainage gap 5a, 5b, 5c which forms in the structure of the shape | mold drainage gap 5c, and is formed in the periphery of the recessed ring 3 is according to the structure of said blade." "Type drainage gap 5a" "Type drainage gap 5b and" Production of the product of the present invention is completed by forming each of them so as to have a structure of the "type drainage gap 5c."

This construction state of the present invention will be described.

After drilling the vertical hole 8 into the ground of the soft ground 6, hinge the cover plate 10 which is opened and closed by earth pressure or ground to the lower end of the steel pipe (9) formed longer than the depth of the vertical hole (8) Steel pipe plate (9) of the structure bonded to be inclined to be opened and closed slightly inclined to (11), and drainage gaps (5) (5a) (5b) (5c) are formed in the periphery of the steel pipe (9). The pleated drainage pipe 1 for filtration continuously forming the indented ring 3 and the protruding wheel 4 is inserted into the length of the steel pipe 9 by the pleated vertical drainage pipe 1a for filtration, and the vertical hole 8 In the state inserted into the end of the deep end of the pipe) cut the pleated vertical drainage pipe (1a) of the filtration portion longer than the upper end of the steel pipe (9), and then pull out the steel pipe (9) from the vertical hole (8) In this case, only the pleated vertical drainage pipe 1a for filtration is installed in the vertical hole 8 drilled in the soft ground 6.

As such, the pleat vertically rushes to the surface of the soft ground 6 while forming sand and gravel on the surface of the soft ground 6 in which the pleated vertical drainage pipe 1a is embedded to form a drainage layer 13. The pleated horizontal drainage pipe 11 having the same structure as that of the pleated vertical drainage pipe 1a is installed on the drainage pipe 1a so as to be bundled, and the drainage fresh water passage 12 is formed below both ends of the drainage layer 13. Then, both ends of the pleated horizontal drainage pipe 11 for filtration horizontally installed on the drainage layer 13 are installed to protrude up to the drainage freshwater passage 12.

At this time, the drainage layer 13 is laminated to an appropriate thickness so that the pleated horizontal drainage pipe 11 for filtration is completely embedded, and then piles up the soil soil 14 to a suitable height according to the geological state of the soft ground 6, Complete the construction installation work of the invention.

In the present invention, when embedded in the ground, the concave wheel (3) and the protruding wheel formed by cutting a plurality of drainage gaps (5) (5a) (5b) (5c) to smoothly absorb the moisture in the ground The pleat drainage pipe (1) for forming (4) is wound in a rolled manner for use as the pleat vertical drainage pipe (1a) for filtration, and is ready for easy use when necessary.

The present invention as described above is cut in the structure of the micro-gap in the inlet ring (3) of the pleat drainage pipe (1) for filtration pleat drainage pipe (1) as in the prior art drainage gap (5) (5a) (5b) (5c) By forming the bay, the production of the present invention can be completed simply and easily, greatly reducing the production cost, and even if the side pressure increases during use, the soft ground without clogging the drainage gaps 5, 5a, 5b, and 5c. Water (moisture) 7 contained in the inside of (6) penetrates smoothly into the feed pipe 2 of the pleat vertical drainage pipe 1a for filtration. Further, water (moisture) 7 of the soft ground 6 penetrates into the drainage gaps 5, 5a, 5b and 5c formed by cutting around the pleated vertical drainage pipe 1a for filtration. As the fresh water is filled and filled in the conveying path 2 which is the inside of the pleated drainage pipe 1, the pleated drainage pipe 12 flows down into the drainage freshener 12 by the pleated horizontal drainage pipe 11 for filtering. By draining the water (7) that flows into the drainage freshwater passage (12), the water (moisture) 7 continues to be deodorized in the soft ground (6).

As the water 7 in the soft ground 6 is deodorized in this way, the strength of the soft ground 6 increases, and the ground of the soft ground 6 gradually goes down by the load of the fill soil 14. At this time, the drainage function is smoothly exerted by the drainage gaps 5, 5a, 5b and 5c formed at the circumference of the corrugated drainage pipe 1, and the sinking state of the ground is not uniform. If not, as shown in Fig. 4, even if the drainage layer 13 is uneven or broken, the pleated pleat horizontally hung on the front end of the pleated vertical drainage pipe 1a embedded in the ground of the soft ground 6 Since the drainage pipe 11 maintains the drainage path, the dehydration function of the soft ground 6 is continuously maintained while the dewatering function is continuously performed, thereby increasing the strength of the soft ground 6. .
