According to the present invention, a plurality of synthetic resin pipes are laminated and bonded in two layers so that their respective axial directions are parallel to each other, but the composite resin pipes of the same layer are bonded to the synthetic resin pipes of the mating layer without being bonded to each other, thereby increasing rigidity and dewatering. The present invention relates to a multi-pipe jointed drain member capable of efficiently discharging and removing moisture contained in soil by expanding a converted area.

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. Looking at it 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 water rises along the drainage groove D formed between the projections 12 by the capillary phenomenon and is 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. .

That is, while the hole pipe has the advantage of excellent rigidity and constant drainage performance, there is 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.

In addition, due to the formation of wrinkles in the perforated pipe and wing wrinkle drainage pipe, the complexity of the device for forming wrinkles increases the manufacturing cost, and the rigidity is also reduced, so that the drainage capacity is lost while being buried by earth pressure while buried in the ground. This happens frequently.

The present invention is to solve all the problems of the conventional type drain member, such as a drain board used to remove moisture in the soft ground, or a hole board, or a drain board integrated hole pipe with a wing serving as a drain board. In order to achieve the role of perforated pipe and drain board at the same time, as well as to reduce the manufacturing cost, it has a rigidity superior to the conventional perforated pipe or drain board in the embedded state It is an object of the present invention to provide a drain member capable of maximizing deformation resistance.

The above object of the present invention is achieved by a joint structure of a plurality of synthetic resin tubes.

The multi-body joint drainage member of the present invention has a technical feature in a structure in which a plurality of synthetic resin pipes are joined in two layers so that rigidity is improved and dehydration conversion area is increased.

In the drain member of the present invention as described above, the plurality of synthetic resin tubes are arranged in parallel so as not to contact each other on two horizontal surfaces parallel to each other, and then the central axes of the upper and lower synthetic resin tubes arranged on the two horizontal surfaces are cross-sectional views. In the phase, it is a structure in which synthetic resin tubes on the other horizontal plane are joined to synthetic resin tubes on one horizontal plane so as to be mutually inconsistent with each other without being coincident with each other.

That is, the synthetic resin pipes arranged on the same horizontal plane are not bonded to each other, and the synthetic resin pipes on one horizontal plane are joined between two synthetic resin pipes on the other horizontal plane, and together with the hollows of the respective synthetic resin pipes, between the two synthetic resin pipes arranged on the same horizontal plane. Edo has a structural feature in that the drain groove is formed.

At this time, the outer diameter and the inner diameter of each synthetic resin pipe are about 4-6 mm and 3-5 mm, respectively, and the separation distance between the synthetic resin pipes located on the same horizontal plane is about 2-4 mm, and a plurality of synthetic resin pipes have a two-layer structure. The width and length of the final drainage member used in the bonded state are approximately 90-100 mm and 15-50 m, respectively.

In addition, a plurality of through holes are formed in each synthetic pipe, or the entire incision or partial repetitive incision is made from one side to the other end along the axial direction, thereby allowing each synthetic resin pipe to penetrate in the longitudinal direction from the outside of each synthetic pipe. Moisture can enter.

The drainage member of the present invention having the structure as described above may be manufactured by a method of joining a plurality of synthetic resin pipes after manufacturing each, and may be manufactured by extrusion so that a plurality of synthetic resin pipes are bonded, It is more preferable to manufacture by extrusion in order to improve productivity and reduce manufacturing cost.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

3 is a perspective view of the first embodiment multi-body joint drainage member of the present invention, FIG. 4 is a perspective view of the second embodiment multi-body joint drainage member of the present invention, and FIG. 5 is a third embodiment of the multi-body joint drainage member of the present invention. 6 is a cross-sectional view of the multi-body joint drain member according to the first embodiment of the present invention.

As shown, the multi-body joint drain member of the present invention,

A plurality of one side synthetic resin pipes 31 arranged in parallel with each other on one side horizontal surface P;

A plurality of laminated on the plurality of one side of the synthetic resin tube 31 in a state arranged on the other horizontal plane (P ') so that each of the plurality of one side of the synthetic resin tube 31 and the center axis is parallel to each other in the up and down directions The other side of the synthetic resin pipe (32).

That is, in the drainage member of the present invention, a plurality of synthetic resin pipes are stacked in two layers of upper and lower, and each synthetic resin pipe of one layer is made of two synthetic resins of the other layer so that each synthetic resin pipe of two layers does not coincide in the up and down directions. The structure is located between the tubes.

At this time, the outermost synthetic resin pipes of all the synthetic resin pipes arranged on the two horizontal planes (P) (P '), the joint is only in one part, not the two parts and the synthetic resin tube directly in contact with the inside of itself in the layer that does not belong. Is done.

For example, if two horizontal planes, i.e., the number of synthetic resin pipes of two layers are the same, one outermost synthetic resin pipe on each side of the two layers cannot be located between the two synthetic resin pipes of the opposite layer, In this case, the two outermost synthetic resin pipe heads on both sides of the other layer may not be located between the two synthetic resin pipes of one layer.

In the multi-pipe jointed drain member of the present invention having the structure as described above, the entire outer surface thereof is wrapped by a filtration member 2 such as a nonwoven fabric, and the hollow H1 of each synthetic resin tube 31, 32 is drained. A plurality of through holes (H2) are formed in each of the synthetic resin pipes 31 and 32 so as to serve as a groove, or a complete incision that cuts the inner and outer circumferential surfaces over the entire length of each of the synthetic resin pipes 31 and 32. (C) Or, a number of partial incisions (C ') in the form of partially broken without extending over the entire length must be formed.

In addition, the groove G between the two synthetic resin pipes positioned on the same horizontal plane is also blocked by the filtration member 2, so that the water passing through the filtration member 2 rises as the outer opening thereof is blocked. Will be

Each synthetic resin tube constituting the multi-tubular joint drainage member of the present invention as described above can have a variety of cross-sectional shapes regardless of the cross-sectional shape, for example, as shown in FIG. In addition, it may be in the shape of a triangular tube, a square tube, or the like, and may be changed into various cross-sectional shapes.

In this case, when the shape of the synthetic resin tube has a flat surface such as a triangular tube or a square tube, it may be a structure joined to both sides of the same horizontal plane, not a pair of virtual horizontal planes apart from each other, unlike the circular tube. .

As described above, the multi-pipe joint drain member according to the present invention has multiple drainage joints in a two-layered structure, so that the dehydration conversion area is increased and the rigidity is significantly larger than that of a conventional drain board, a hole pipe, or a wing hole pipe. As well as the improvement, the deformation time due to the earth pressure is reduced, the drainage capacity retention time is extended, there is an advantage that it is possible to reduce the manufacturing cost compared to a single corrugated hole tube during manufacture by extrusion.
