Description

Draining corrugated pipe

In order to build various buildings or structures such as houses, factories, roads, and embankments on soft grounds such as riversides, lakes and swamps, the construction of reinforcing the strength of soft grounds by discharging moisture contained in the soft grounds to the ground must be preceded. The stability of the building or structure to be built later can be secured.

To this end, the oldest method of water removal is to excavate the ground to make a cylindrical drill hole, and then to fill the sand with excellent absorbency, so that the water contained in the ground is discharged by capillary along the sand column. However, since it is very low in efficiency, it is rarely used in recent years.

Referring to the drain board generally used nowadays, the drain board is a plurality of leaf parallel to each other from the upper end to the lower end of the plate so that a plurality of valleys, that is, drainage grooves are formed along the longitudinal direction on each side of the rectangular shaped plate Or it is a structure in which a large number of elongated plate-like protrusions such as a flange is upright, and the outer surface is embedded in the soil while wrapped with a filtering member such as a nonwoven fabric.

In the drain board as described above, only the moisture contained in the soil passes through the filtration member and moves to the plate body, and this moisture rises along the drain groove formed between the protrusions by capillary action and is discharged to the ground surface through the upper end of the drain board. do.

However, as the moisture contained in the soil is discharged, the ground subsides, and the sinking ground strongly presses both sides of the drain board, so that the filtration member is recessed and adhered to each flat surface side of the plate, and drainage between the protrusions. The grooves become extremely small or, in severe cases, almost disappear.

That is, as the drain groove is reduced or disappeared, the drainage performance of the drain board is drastically lowered, or the drainage performance cannot be exhibited at all.

Further, since the plate body of the drain board has a structure in which a plurality of projections perpendicular to the longitudinal direction are erected in parallel with each other on both sides thereof, the widthwise bending deformation resistance is sufficiently high, and the longitudinal bending deformation resistance is small, so that along the longitudinal direction Bar plate can be easily be banded with a small force, there is a problem that the formation of the drainage groove is impossible as the plate is dried or crushed by the earth pressure.

Perforated pipes, which are other drainage members, were developed to solve various problems of the plate drain boards as described above, and are formed in the pipe wall not in the form of flat straight pipes along the axial direction. Spiral corrugated hole pipes are formed in which a plurality of through holes are formed.

Since the corrugated pipes have a high rigidity, there is no fear that the hollows of the pipes serving as drainage grooves may be blocked, so that the drainage performance does not decrease with time, but the dehydration conversion cross-sectional area is inferior.

In addition, when looking at the uneven-type wing corrugated drainage pipe having a large dehydration conversion cross-sectional area of Korean Patent Laid-Open Publication No. 1999-78935, the wrinkle drainage pipe has a problem that the contact area with soil increases but the drainage groove decreases or closes with time. have.

An object of the present invention was devised to solve the above problems, and to provide a drainage corrugated pipe for drainage of the drainage pipe of the corrugated hole due to the earth pressure of the nonwoven filter cloth.

In addition, another object of the present invention is to provide a corrugated pipe for drainage that does not bend or bent the shape of the core material due to earth pressure.

In order to achieve the above object, the corrugated pipe for drainage of the present invention is a corrugated pipe made of a core material 10 consisting of a hollow cylindrical tube formed with corrugations and a filtration nonwoven fabric 20 covering the outside of the core material. Ash is one or more strength reinforcing portion 30 is formed in a straight line along the longitudinal direction of the core material,

The strength reinforcing portion 30 has an upper side is open and protruding to the lower side, the depth (d) is formed deeper than the height (h) of the wrinkles of the core material,

The lower surface of the lower side of the strength reinforcing portion 30 is characterized in that a plurality of drain holes are formed at regular intervals.

According to a preferred embodiment, the depth (d) of the strength reinforcing portion with respect to the diameter (D) of the core material is characterized in that 1/10 to 3/10 (d / D).

According to the present invention, even if the sinking ground is pressed against both sides of the corrugated oil pipe, the nonwoven filter cloth is in close contact with the inside of the corrugated oil pipe, so there is no fear of clogging the drain hole formed at the end of the deep reinforcing portion of the deep bent pipe. have.

In addition, since the strength reinforcing portion forms a rib reinforcing structure in the drainage corrugated pipe of the present invention, when buried in the ground, there is a strong and structurally stable effect on external pressure.

In addition, the corrugated drainage pipe for drainage of the present invention discharges the pore water of the basement to the ground to sink the ground uniformly and quickly has the effect of ensuring stability even after the construction of the building or structure.

Hereinafter, with reference to the accompanying drawings, it will be described in more detail with respect to the corrugated pipe for drainage of the present invention.

Referring to Figure 1, the pleated perforated pipe for drainage of the present invention consists of a core material 10 made of a hollow cylindrical tube formed with a pleat as in the prior art and a filter nonwoven fabric 20 is deposited on the outer peripheral surface of the core material 10. .

According to a preferred embodiment of the present invention, the present invention includes one or more strength reinforcing portions 30 formed in the core material 10.

Looking in more detail, the core material 10 is formed with one or more strength reinforcing portion 30 formed in a straight line along the longitudinal direction of the core material 10, the strength reinforcing portion 30 is the upper side is opened , The lower side has a protruding shape. The depth d of the strength reinforcing portion is formed deeper than the height h of the wrinkles. In addition, one or more drain holes 40 are formed at regular intervals on the bottom of the strength reinforcing part 30.

According to a preferred embodiment, the interval of the drain hole 40 is preferably 1 ~ 1.5cm but is not necessarily limited thereto.

Next, Figure 2 is a cross-sectional view of the corrugated pipe for drainage according to a preferred embodiment of the present invention.

Referring to FIG. 2, a filtration nonwoven fabric 20 is deposited on the outer circumferential surface of the core material 10, and a plurality of strength reinforcing portions 30 are formed inside the core material 10.

Looking in more detail, the strength reinforcing portion 30 is formed on the four sides of the upper, lower, left and right of the core material 10 by forming the strength reinforcing portion 30, the four strength reinforcing portion 30 serves as a column, the strength The drain hole 40 is formed at the bottom of the reinforcement part 30.

In particular, the appearance standard of the core material 10 has a diameter of 35 to 50 mm and the depth of the strength reinforcing part 30 is 5 mm, and the depth of the strength reinforcing part 30 with respect to the diameter D of the core material 10 is Preferably about 1/10 to 3/10 (d / D). On the other hand, the depth of the strength reinforcing portion 30 is formed deeper than the height of the wrinkles.

Therefore, even if the sinking ground is pressed against both sides of the corrugated hole, the nonwoven filter cloth is in close contact with the inside of the corrugated hole, so that the filtration nonwoven fabric does not come into close contact with the inside of the strength reinforcing part 30, so that the gap water penetrating into the strength reinforcing part 30 is drained. It is smoothly drained through the 40.
