Description

Horizontal drain board manufacturing method {Horizontal drain board manufacturing method}

The present invention relates to a method of manufacturing a horizontal drainage material that improves a soft ground by draining moisture contained in the ground.

If the ground subject to construction work is a soft ground with a high water content, the ground water is first discharged to consolidate the ground to increase the shear strength of the ground and then perform the foundation work.

In the construction of such a soft ground, groundwater can be discharged in a variety of ways.The method of removing groundwater from the strata by laying sand or crushed stone on the strata as drainage material and filling the top of it is used, but recently, collecting crushed rock or sand. To minimize environmental damage and reduce construction costs, drainage materials called drain boards are often used.

Drain boards are made of synthetic resin materials, are much cheaper than sand, and have high efficiency in terms of performance, so they are widely adopted in soft ground improvement sites. A wide horizontal drainage material (drain board) is used, and groundwater is discharged more easily by connecting it directly to the vertical drainage material.

Fig. 18 shows a conventional drain board. In the conventional drain board, an upper surface (4a) and a lower surface (4b) are alternately arranged, and a plurality of partition walls (5) are formed on the upper surface (4a) and the lower surface (4b). It is configured to include a core (3) and a filter material (2) installed to surround the outer surface of the core (3).

The conventional drain board in FIG. 18 has a disadvantage in that the drainage passages are alternately formed up and down, and as shown in FIG. 19, the effective outflow sectional area (shaded portion) through which groundwater drained by the vertical drainage material 7 flows out is small, The conventional horizontal drainage material 6 shown in FIG. 20 also has a disadvantage in that the effective outflow cross-sectional area (shaded portion) is small.

In addition, since the conventional drainage material has a structure in which water passes under the core, water is inevitably saturated in the ground under the horizontal drainage material, and thus there is a problem in that constructability and equipment runability are deteriorated.

After the horizontal drainage material is installed, an embankment layer is formed thereon, and groundwater is discharged by the top pressure of the embankment layer.The conventional horizontal drainage material is deformed by the pressure of the embankment layer, causing the flow path to be blocked or narrowed. There was.

In order to prevent deformation of the horizontal drainage material, the rigidity of the horizontal drainage material core must be increased.If the overall rigidity of the core is increased, there is a problem that the manufacturing cost of the core increases, and in order to increase the rigidity of the core, the thickness of the core member is thick. As a result, the manufacturing cost increases, whereas the channel area becomes smaller as the thickness of the member becomes thicker.

In addition, since the conventional horizontal drainage core is injection-molded by the die method, it is difficult to make various cross-sectional shapes of the core and drill the drainage holes according to it, making it difficult to create a core structure that maximizes rigidity and water permeability. There is a disadvantage that the physical properties of the material are deteriorated because it adopts a water cooling method of cooling by dipping.

Therefore, a method of manufacturing a horizontal drainage material having a structure that increases the stiffness of the horizontal drainage core, a manufacturing method of a horizontal drainage material that can maximize the effective outflow cross-section while increasing the stiffness of the core, and manufacturing while maximizing the stiffness and outflow cross-sectional area of the core It was necessary to develop a method of manufacturing a horizontal drainage material that could facilitate the process.

The method of manufacturing a horizontal drainage material of the present invention has the following effects.

First, since the core of the present invention adopts a method of manufacturing the upper member and the lower member separately and then bonding them to each other, it is easy to form the cross-sectional shape of the upper member, and the drain hole is easily drilled. According to the present invention, the cross-sectional structure of the upper member can be formed into a honeycomb structure close to the regular surface by the production method by the roll compression method, so that the load of the embankment layer can be easily distributed to the left and right, and the top plate, the swash plate, Since the arch structure is formed by the inner plate (outer plate), it is possible to obtain a structure in which water can easily flow out between the swash plates and a load supporting structure by the arching effect. That is, in the present invention, since the upper member and the lower member are separately manufactured, the cross-sectional structure of the upper member can be manufactured in a honeycomb structure. As a result, a horizontal drainage structure that does not cause deformation and sagging can be obtained while securing a maximized flow path area. have.

Second, by separately manufacturing the core upper member and the lower member of the present invention and the method of manufacturing the core by bonding the upper member and the lower member, the rigidity of the horizontal drainage core can be increased without increasing the amount of material. In addition, while increasing the rigidity of the core, the effective outflow cross-sectional area can be maximized, and a structure of a horizontal drainage material capable of efficiently forming drainage holes formed in the upper member can be obtained.

Third, joint portions are provided on both sides of the upper member in the width direction, and the joint portion is joined to both sides in the width direction of the lower member, so that the upper load transmitted to the upper plate, the swash plate, and the outer plate can be resisted by the adhesive force of the joint portion. In other words, the joint portion of the present invention exhibits a synergistic effect in that a structure that resists a load transmitted from the upper portion can be provided in addition to the effect of forming a flow path inside the core by joining the upper member and the lower member.

Fourth, in the present invention, since the upper member is manufactured by a roll compression method and the lower member is prepared separately and the core is manufactured by joining the two, compared to the core manufacturing by the conventional die method, the core is formed and drainage holes. There is an advantage that drilling work becomes easy.

Fifth, in the horizontal drainage material manufactured by the manufacturing method of the present invention, the stiffness of the core is increased in the part where the pressure of the embankment layer acts large, and the stiffness of the core is decreased in the part where the pressure is small, while lowering the manufacturing cost. It is not easily sag or deformed by pressure, so flow channel blockage does not occur.

Sixth, in the horizontal drainage material manufactured by the manufacturing method of the present invention, since the core is formed in a plurality of polygons, the plurality of polygons are configured by sharing an adjacent polygon and an inner plate, and a drain hole may be formed by a shared inner plate, one Even when the water passage capacity is exceeded, the water collection effect and drainage performance are high because drainage can be performed through other adjacent channels.

Seventh, in the case of manufacturing the earth pressure dispersion type core by the manufacturing method of the present invention, since a strong part is arranged in the middle of the core, the upper pressure is efficiently distributed and supported, and a flow path between the strong parts Since large areas are arranged, in addition to efficient earth pressure distribution, efficient drainage performance can be secured.

Eighth, in the present invention, since the upper member and the lower member of the core are separately manufactured or prepared, and the drain hole is formed only in the upper member by a perforator before joining the upper member and the lower member, the drain hole can be accurately formed at the required position. . At this time, if the drain hole is drilled so as to communicate with the swash plate and the inner plate, all required drain holes can be formed in a single drilling process, so manufacturing is easy and fast, and manufacturing cost is reduced. It is an easy structure to flow into the flow path through the goal of, and water can be passed through the neighboring flow paths. In addition, since the lower member does not have a drainage hole and has a closed structure, the ground under the horizontal drainage material can be maintained in a dry state, thereby maintaining workability and equipment runability in a good state.

Ninth, since the upper member of the present invention produces the molten material by the roll compression method, there is no deterioration in the quality of the material, and it is easy to make various shapes required.

Tenth, the inner plate of the upper member functions to support the load of the embankment layer and forms a partition wall above the lower member to form a flow path divided into several. At this time, the upper member and the lower member are joined only by the joints on both sides in the width direction. , Since the inner plate and the lower member of the upper member are not bonded to each other, since a fine gap is formed between the inner plate and the lower member, there is an effect of enabling drainage between the passage and the adjacent passage.

Eleventh, since the upper member and the lower member are joined by ultrasonic bonding, the joining operation can be made quickly and conveniently, and uniform and constant adhesion can be obtained over the entire length of the joint.

However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and similar reference numerals are assigned to similar parts throughout the specification.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows an embodiment of a horizontal drainage material manufactured by the manufacturing method of the present invention. As shown in Figure 1, the horizontal drainage material 300 manufactured by the manufacturing method of the present invention includes a core 100 including an upper member 110 and a lower member 120 and the outside of the core 100. It consists of an enclosing filter 200.

A flow path 130 is provided in the inner space of the core 100 to discharge ground water that has moved upward by the vertical drainage 7 in the horizontal direction.

In the conventional horizontal drainage material, a core was manufactured by injection by a die method without separately manufacturing the components constituting the core, but in the present invention, the configuration of the core 100 is divided into an upper member 110 and a lower member 120, After the upper member 110 and the lower member 120 are separately manufactured, the core 100 is manufactured by bonding. Thereafter, the horizontal drainage material 300 is completed through a process of enclosing and sealing the filter 200 outside the core 100.

The upper member 110 is manufactured in a roll compression method by the molding unit 20 to be described below, and the lower member 120 may be a ready-made product or may be separately manufactured at an upper member manufacturing site.

The upper member 110 and the lower member 120 may be made of polypropylene (PP, polypropylene) or polyethylene (PE, polyethylene).

To join the upper member 110 and the lower member 120, joint portions 111 are integrally provided on both sides of the upper member 110 in the width direction, and the joint portion 111 is attached to the lower member 120. The core 100 is manufactured by bonding to both sides in the width direction. In this case, bonding may be performed by ultrasonic bonding.

3 is a cross-sectional view of the upper member 110 and the lower member 120.

As shown in FIG. 3, the lower member 120 is manufactured in the form of a single plate or sheet formed elongated. Since a drain hole is not formed in the lower member, water flowing into the flow path does not flow below the lower member.

The upper member 110 includes an upper plate 112, a swash plate 113, an inner plate 114, and two outer plates 115, and a joint 111 is provided on one side of the outer plate 115.

Two or more upper plates 112 may be provided, and form an upper portion of the core 100. The upper plate 112 may have a horizontal planar shape or a convex upward shape as shown in FIG. 10. When the convex shape is formed, drainage from the top plate to the swash plate and the drain hole can be made more smoothly, and the longitudinal flexural rigidity of the core is increased.

The inclined plate 113 is provided to be inclined between the upper plate 112 and the upper plate 112 and next to the outermost upper plate 112, and connects the upper plate 112 and the inner plate 114 or the upper plate 112 and the outer plate 115 do.

6 and 7, the swash plate 113 transfers the load transmitted by the upper plate 112 to the inner plate 114 and the outer plate 115, and the ground water discharged above the upper plate flows along the swash plate. To induce them.

The inner plate 114 is formed downward from the bottom where the two inclined plates 113 meet.

As shown in FIGS. 6 and 7, the inner plate 114 supports the load transmitted to the swash plate 113 and serves as a partition wall above the lower member 120 to form the flow path 130.

Since the inner plate 114 must support the earth pressure of the upper portion, the thickness of the inner plate 114 may be thicker than that of the upper plate 112, the swash plate 113, and the outer plate 115.

The outer plate 115 is formed downward from the bottom of one swash plate 113, and is provided with one, that is, two each on both sides of the upper member in the width direction.

As shown in FIG. 7, the outer plate 115 supports the load transmitted to the swash plate 113 and transfers it to the joint 111 located below, and acts as a partition wall at the top of the lower member 120 to serve as a passage ( 130) is formed.

The flow path 130 includes a space surrounded by the upper plate 112, the swash plate 113, the inner plate 114 and the lower member 120, and the upper plate 112, the swash plate 113, the inner plate 114, It is formed by a space surrounded by the outer plate 115 and the lower member 120. As shown in FIGS. 6 to 9, the flow path may have a hexagonal shape.

It is preferable that the inner plate 114 and the outer plate 115 are formed perpendicular to the lower member. If it is formed vertically, it has the advantage that the bearing capacity for the upper load is increased compared to the inclined one, and the forming operation by roll compression is easy.

In addition, a bonding portion 111 is provided outside the outer plate 115. The bonding portion 111 is preferably provided integrally with the outer plate, and is bonded to both sides in the width direction of the lower member 120 located below.

The bonding part 111 not only has the effect of making the core easier by bonding the upper member and the lower member, but also has a special effect of supporting the load transmitted to the upper plate, the swash plate, and the outer plate by the adhesive force of the joint as shown in FIG. Will also be exerted. Therefore, not only can the core be manufactured by the joint, but also the effect of minimizing the deformation of the core by the joint can be obtained.

At this time, the bonding of the upper member and the lower member is made only in the bonding portion 111, and the inner plate 114 and the lower member 120 are not bonded. The inner plate 114 is formed vertically with the lower member, and the load acts symmetrically from both sides with respect to any one inner plate, so even if it is not bonded, the support force of the inner plate is not affected, and the inner plate 114 and the lower member 120 ), it is possible to pass water through the fine gaps that are not adhered, so there is an effect of enabling drainage between the flow path and the flow path.

The upper plate 112, the swash plate 113, the inner plate 114, the outer plate 115, and the joint 111 may be integrally formed.

In addition, a drain hole 116 is formed to discharge the ground water through the flow path. The drain hole 116 may be formed in the upper plate and the swash plate (see FIG. 8 ), and may be formed so as to communicate with each other where the swash plate and the inner plate meet, as well as the upper plate and the swash plate (see FIG. 9). If the drain hole is formed at the place where the swash plate and the inner plate meet as shown in FIG. 9, a drain hole capable of simultaneously performing vertical drainage and horizontal drainage can be formed in a single drilling process, so a horizontal drainage material having a large drainage effect can be obtained through a simple working process.

As shown in Fig. 6, the horizontal drainage core manufactured by the manufacturing method of the present invention can form a honeycomb structure in which each cross-sectional structure is close to a regular cube, and has a structure that is easy to distribute the load of the upper side to the left and right, Since the arch structure is formed by the upper plate, the swash plate, and the inner plate (outer plate), a load supporting structure by the arching effect can be obtained.

Therefore, the horizontal drainage material manufactured by the manufacturing method of the present invention secures a significantly increased flow path area (shaded portion) compared to the conventional horizontal drainage material, as shown in FIG. 2, while minimizing the occurrence of deformation and sagging by the above structure. A horizontal drainage structure can be obtained.

Embodiments of the arrangement structure of the flow path of the horizontal drainage material manufactured by the manufacturing method of the present invention can be divided into an earth pressure concentration type and an earth pressure distribution type.

As shown in Figs. 3 and 4, the earth pressure concentration type has a structure in which the flow path 130 increases from the center line toward both sides.

When the embankment layer is formed on the horizontal drainage material, the central part of the horizontal drainage material receives a lot of earth pressure and both sides receive less earth pressure. This structure is taken to increase the stiffness of the part that receives a lot of earth pressure.

This structure can be made by making the height and thickness of the inner plate the same, but increasing the installation distance of the inner plate as it goes from the center to both sides, and since the spacing of the inner plate decreases toward the center, the rigidity increases.

As a method of making the earth pressure intensive horizontal drainage material, a compression roller may be used so that the thickness of the inner plate is formed differently. That is, the height of the inner plate and the installation interval of the center line of the inner plate are the same, but it can be made by increasing the thickness of the inner plate as it goes from both sides to the center, and the thickness of the inner plate becomes thicker as it goes to the center, so the rigidity increases.

When the earth pressure intensive horizontal drainage material is installed in a long section in the longitudinal direction such as the road embankment, it may be effective if it is installed in the longitudinal direction.

The earth pressure dispersion type is a type in which a flow path having a relatively small cross-sectional area and a flow path having a relatively large cross-sectional area are alternately formed as shown in FIG. 5.

The earth pressure dispersion type is a structure capable of effectively dispersing earth pressure by alternately forming a part with high rigidity and a small part, and since there is no loss of flow path while distributing earth pressure, the drainage performance can be maintained as it is.

The earth pressure dispersion type horizontal drainage material can be made by making the height and thickness of the inner plate the same, but alternately forming the inner plate with a large and small installation interval.

As a method of making the earth pressure dispersion type horizontal drainage material, a compression roller may be used so that the thickness of the inner plate is formed differently. That is, the height of the inner plate and the installation interval of the center line of the inner plate are kept constant, but the thickness of the inner plate may be formed by alternately forming a relatively thick and thin inner plate.

When the earth pressure dispersion type horizontal drainage material is installed in a long section in the longitudinal direction such as the road embankment, it may be effective if it is installed in the transverse direction.

Both the earth pressure concentration type horizontal drainage material and the earth pressure distribution type horizontal drainage material may be formed to have a symmetrical cross section with respect to the center line.

The core manufactured by the conventional die method had limitations in implementing its shape and structure, but the present invention is a method of separately manufacturing the upper member, and the upper member is manufactured by the roll compression method, so the upper and lower molding rollers are different. Thus, it has a special effect of easily manufacturing upper members and cores having various structures and shapes.

The filter 200 may be configured to surround the outer peripheral surface of the core 100. By the filter 200, foreign substances such as soil which are mixed with water and which are intended to enter the core are filtered out. The filter 200 may be manufactured using a nonwoven fabric.

Hereinafter, a method of manufacturing a horizontal drainage material will be described.

First, the upper member 110 and the lower member 120 are prepared.

The molding unit includes an upper molding roller 21 and a lower molding roller 22, and the surfaces of the upper molding roller 21 and the lower molding roller 22 may be provided according to a desired cross-sectional shape of the upper member. In the embodiment, the upper plate 112, the swash plate 113, the inner plate 114, the outer plate 115, and the joint 111 may be formed in a structure.

Since the upper member formed by the upper molding roller 21 and the lower molding roller 22 is in a high temperature state, it is cooled by air cooling by a cooler 25 that discharges cooling air. In the present invention, unlike the conventional water cooling type, since the upper member is cooled by air cooling, deterioration of material properties does not occur.

Before the upper member 110 and the lower member 120 are joined, a drain hole 116 is formed in the upper member 110. The drain hole is formed by a perforator 14.

Then, the core 100 is manufactured by bonding the upper member 110 and the lower member 120 with drain holes formed thereon.

The bonding process is carried out in an ultrasonic bonding device. The upper member 110 having the drain hole perforated is transferred over the bed 19 of the ultrasonic bonding device, and the lower member 120 is wound in a roll shape and then unwound while It is supplied to overlap the member.
