The present invention, by combining a plurality of holes and a plurality of drain boards having an overlapping structure with alternately formed holes and corrugations, respectively, to efficiently drain and remove the water contained in the soil, drain board and perforated pipe integrated composite drainage It is about absence.

In order to build various buildings or structures such as houses, factories, roads, and embankments on soft grounds such as rivers, 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. By doing so, the stability of buildings or structures to be built afterwards can be ensured. Looking at the water removal method carried out for construction work on land containing considerable amounts of water, such as soft ground, as follows.

The oldest water removal method is to excavate the ground to make a cylindrical drill hole, and then fill the inside with sand with excellent absorbency, so that the water contained in the ground is discharged by capillary action along the sand column. For example, since the efficiency is very low, it is rarely used in recent years, and nowadays, it is common to use a plate drain board or a perforated tube formed through a pipe wall through a plurality of through holes penetrating the inner and outer circumferential surfaces. As follows.

As shown in FIG. 1, the drain board 1 has a plate body 11 such that a plurality of valleys, that is, drainage grooves D, are formed along the longitudinal direction on both sides of the plate body 11 having a rectangular shape. A structure in which a plurality of plate-like protrusions 12 whose length is relatively longer than a width, such as a plurality of ribs or flanges parallel to each other from the upper end portion to the lower end portion, is upright, and the outer surface thereof is wrapped with a filtering member 2 such as a nonwoven fabric. As it is buried in the soil.

Therefore, when the drain board 1 is vertically embedded in the soil, as shown in FIG. 2, only moisture contained in the soil passes through the filtering member 2 to move toward the plate body 11. This moisture is raised along the drainage groove D formed between the projections 12 by the capillary phenomenon and then discharged to the ground surface through the upper end of the drain board 1.

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 1, so that the filtration member 2 has the protrusions 12 and the plate ( 11) while being in close contact with each flat surface side, the drainage grooves D between the projections 11 become extremely small or, in severe cases, almost disappear.

That is, as the drainage groove D is reduced or disappeared, the drainage performance of the drain board 1 is drastically lowered, or the drainage performance cannot be exhibited at all.

In addition, since the plate body 11 of the drain board 1 is a structure in which a plurality of projections 12 perpendicular to the longitudinal direction are erected in parallel to both sides thereof, the width direction bending deformation resistance is sufficient, but the length direction bending is sufficient. Since the deformation resistance is small, the plate 11 can be easily bent even with a small force along the longitudinal direction, and the plate 11 may be dried or crushed by earth pressure, thereby making it impossible to form the drain groove. .

The hole tube, which is another drainage member, was developed to solve various problems of the plate drain board as described above. Instead of a flat straight tube along the axial direction, spiral unevenness is formed on the wall of the pipe. Spiral corrugated pipes with a plurality of through holes penetrating the outer circumferential surface are used.

In addition, the above-mentioned hole pipe, like the drain board, is buried in the deductive ground in a state in which the filtration member is wrapped on its outer peripheral surface, unlike the drain board, the hollow of the hole pipe that serves as a drain groove because of the rigidity is blocked. There is no concern, and as a result, there is an advantage that the drainage performance does not decrease over time.

However, for example, when comparing an arbitrary perforated tube with a drain board which spreads this perforated tube in the form of a plate based on a straight drain-shaped perforated tube having no unevenness and a flat drain board having no projections, the filter member is interposed. However, only the outer circumferential surface of the perforated tube comes into contact with the soil, but the drain board has both soil contact with the soil, and the soil contact area of the drain board is twice that of the perforated tube. .

In other words, the perforated pipe has the advantage of excellent rigidity and constant drainage performance, but has a disadvantage in that the dehydration conversion cross-sectional area is lower than that of the drain board.

Therefore, a drain board integrated hole pipe has been developed that can have the advantages of a hole and a drain board. In Korean Patent Laid-Open No. 1999-78935, "Wrinkle pleat drainage pipe with a large cross-sectional area of dehydration", domestic registered utility model No. 376585 discloses an "uneven wing corrugated drainage pipe with a larger dehydration conversion cross section."

The patent discloses a structure in which plate-shaped corrugated wings are integrally coupled along the axial direction on both sides of opposite periphery surfaces of the perforated tube, and the filter cloth is wrapped around the outer surface thereof, in which case the contact area with the soil is increased. One, there is a disadvantage that the filter cloth is in close contact with the outer surface of the wrinkles wings.

That is, since a certain drainage groove is not formed between the inner surface of the filter cloth and the outer surface of the pleated wing, it is difficult to improve sufficient drainage performance.

The utility model has a structure in which a plurality of uneven drainage guide grooves parallel to each other along a longitudinal direction are formed on each of both side surfaces of the corrugated wing constituting the published patent. Since the corrugated wing is integrated with the perforated tube, the drainage capacity may be improved as compared to the above-described patent. However, in the case of the corrugated wing, the uneven drainage guide groove may become small or closed as time passes, as in the conventional drain board. have. In other words, the wrinkled wing may not play its role.

The present invention, to solve the problems of the conventional drainage member, such as drain board used to remove the moisture of the soft ground, or a hole board, or a drain board integrated hole pipe combined with a wing that serves as a drain board As well as the role of perforated pipes, as well as having a vertical drainage and horizontal drainage function, but also multiple drain boards and perforated pipes are combined together to maximize drainage efficiency, as well as rock inside the ground It is an object of the present invention to provide a composite drainage member that can be purchased in a free banding state according to the position of the back.

The above object of the present invention is achieved by a unit composite drainage member in which a plurality of plate-shaped drain board portions and a plurality of perforated pipe portions having convex cross-sectional shapes are alternately coupled.

The drain board and the hollow pipe integrated composite drainage member of the present invention have a structure in which a plurality of plate-shaped drainboards in a state in which two sheets are overlapped are alternately coupled by joining a pair of unit composite drainage members. There are technical features to achieve this.

That is, the composite drainage member of the present invention has a structure in which a plurality of hollow boards having hollows are connected to a plurality of plate-shaped drain boards in a straight line, but two drain board portions are overlapped instead of one plate-shaped drain board. In addition to the outer surface, the drain groove is formed between two opposing inner surfaces of the two unit drain board portions forming the drain board.

"와 같이 즉, 일측의 각 유공관부가 타측의 각 유공관부 반대 측으로 볼록하도록 대향한 상태에서, 서로 마주한 유공관부 한 쌍씩이 모두 중공을 가진 관의 형상을 이룰 수 있도록 결합된 구조이다.In the composite drainage member of the present invention, the plate-shaped drain board portion and the convex hollow pipe portions that are convex toward one side are alternately connected on the horizontal plane so that the cross section is "

"It consists of a pair of unit composite drainage members that are shaped, a pair of unit composite drainage members,"

"In other words, in a state in which each of the perforated pipe parts on the opposite side to be convex to the opposite side of each of the perforated pipe parts, the pair of perforated pipe parts facing each other are combined structure to form the shape of the hollow tube.

In this case, the perforated pipe parts facing each other may be symmetrical to each other, but may not be symmetrical, and do not necessarily have a semicircular shape, and the shapes of the two perforated pipe parts joined together may be shaped like a hollow pipe.

In the following description, the opposite side and the opposite side of the unit composite drainage member are defined as 'outside' of each unit composite drainage member and the 'side' as the inner side, based on the state in which the two unit composite drainage members face each other as described above. That is, the one side hole tube portion is convex outwardly opposite to the other side hole tube portion facing each other.

Both surfaces of the perforated tube portion and the drain board portion having the convex cross-sectional shape as described above are formed with a plurality of through-holes at the same time as the corrugation is formed. It may be formed, it may be formed with the wrinkles formed in the longitudinal direction, that is, the vertical direction while being regularly repeated along the direction to form a grid like a checkerboard.

At this time, in the case of the perforated tube portion, the horizontal direction may be an outer circumferential arc direction, and may be formed in an inclined form having a horizontal direction and a slope in addition to the vertical and horizontal wrinkles.

That is, in the case of the drain board part, the diagonal wrinkles may be formed, and in the case of the perforated pipe part, the spiral wrinkles may also be formed.

In addition, it is preferable that the wrinkles of the drain board part and the hole tube part are broken at the boundary between the hole tube part and the drain board part, not in a state where the wrinkles of the drain board part and the hole hole part are connected to each other. In order to form a vertical drainage groove in the lengthwise direction of the perforated pipe on the boundary surface of the perforated pipe part and the drain board part.

The present invention composite drainage member having the structure as described above is embedded in the ground with the filtration member wrapped on its outer surface, the embedded composite drainage member is subjected to the pressure of the soil, in this state, the outer surface of the drain board The corrugations formed in the corrugations are horizontal or vertical drain grooves on the outer surface of the drain board, and the spaces formed by the valleys of the opposite inner surfaces of the two drain board portions overlapping each other are horizontal or vertical drain grooves inside the drain board.

At this time, the water inflow into the horizontal or vertical drain groove formed between the inner surface of the two drain board portion is made by a plurality of through-holes formed through each drain board portion.

In addition, the water flowing into the horizontal or vertical drain grooves formed between the inner surfaces of the two drain board parts and the outer surface overlapped as described above is moved to the perforated pipe side, and the water moved to the perforated pipe side is introduced into the hollow inside of the perforated pipe. In addition, the corrugations of the perforated pipes and the corrugations of the drain boards are not connected to each other, that is, the broken parts are introduced into the vertical drainage grooves formed in a vertical direction along the boundary of the perforated pipes and the drain board, and then are discharged upwardly.

In addition, the water flowing into the outer surface of the perforated pipe is introduced into the hollow through a plurality of through holes, or flows into the vertical drainage groove along the valley of the outer periphery of the perforated pipe and then discharged upwardly.

As described above, in the composite drainage member of the present invention, horizontal or inclined and vertical drainage grooves and the like are formed in both inside and outside of the drain board in which the two drain board portions overlap, and are collected as drain boards along the horizontal or inclined drainage grooves. Moisture is gathered by moving shorter than its own width, rather than long distance, and is then discharged upward along the vertical drainage groove, so that the absorbency of the moisture and the dischargeability are improved.

However, if necessary, the drain board may be composed of only one drain board portion, not a structure in which a pair of drain board portions overlap.

The details of the purpose and technical constitution according to the present invention, including the effect thereof, will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

In addition, regular wrinkles may be formed in the horizontal direction, that is, the width direction, on the inner and outer surfaces of each of the drain board portions 31A and the hole pipe portion 32A. If necessary, the vertical wrinkles may be additionally formed. A plurality of through holes H are formed through the members 31A and 32A.

At this time, the horizontal corrugation of the drain board portion 31A and the horizontal corrugation of the hole pipe portion 32A may be integrally connected to each other, or may have a structure that is broken at the boundary of the two members 31A and 32A. For the flexibility of the member 300, a broken structure is more preferable.

If necessary, the plurality of drain board portions 31A are not constituted by a pair of unit composite drainage members 300 as described above, and are not a plurality of oil holes 32 and a plurality of drain boards 31. It can also be configured as.

That is, as shown in Figure 8, one unit composite draining member 300; It is also possible to comprise only a plurality of hole holes 32A which are coupled to the hole holes 32A of the unit composite drainage member 300 to form the hole holes 32.
