Description

Bunker seat for golf course and bunker structure using same {BUNKER SHEET OF GOLF LINKS AND BUNKER STRUCTURE}

The present invention relates to a golf course bunker sheet, and more particularly, to a golf course bunker sheet and a bunker structure using the same, having a moisture permeation function with an appropriate amount of moisture, and can effectively prevent the loss of sand in the bunker.

A golf game is an athletic game in which a player puts a ball into a number of holes arranged one after another in a fixed position. Generally, the ground of the golf course is mostly made of grass, but for the interest of the game, there are trees forests and water Artificially install terrain obstacles such as pools and sand bunkers.

Bunkers, in particular, are artificial obstacles scattered around the green, filled with sand in the pit, and if the ball of the golfer falls into the bunker during the game, it causes the game to escape from the bunker, have.

Looking at the cross-sectional structure of the bunker with reference to Figure 1, the bunker (1) is dug down like a puddle with respect to the ground, generally, the non-woven fabric 30 is laid on the bottom surface 40 is dug, The bunker sheet 20 is again constructed on the upper portion, and the sand 10 is filled on the bunker sheet 20. On the other hand, the non-woven fabric is provided with a drain (50, dark shade) separately to drain the running water or rainwater flowing into the bunker.

At golf courses, turf or sandy conditions are a very important factor in the game. Particularly, in the bunker, the sand is not cohesive due to its characteristics, and sand on the slope is likely to flow to the center. In addition, when the drainage in the bunker is not made smoothly, the sand itself contains excessive moisture, on the contrary, in the dry weather, the sand is likely to be blown by the wind. The sand in the bunker is of a constant thickness throughout, and only in the right amount of water can the players play well.

Therefore, as shown in order to maintain the optimum sand in the bunker, a drain for smooth drainage is installed in the lower part of the bunker, and in particular, a nonwoven fabric or bunker sheet, etc., for preventing sand from flowing down the slope. Is constructing. However, although the sand can be prevented to some extent by the bunker sheet or the like, there is a demand for a bunker sheet having an appropriate structure for preventing the moisture content and loss of sand.

Golf course bunkers according to the prior art did not function to ensure that the bunker sheet constructed on the bottom surface does not properly collect the sand, the sand contains the appropriate moisture to maintain cohesion. Therefore, the sand on the slope in the bunker easily flows and is lost, there is a problem in management that must be frequently managed.

In order to solve the above problems, the present invention contains an appropriate amount of water irrespective of the external environment such as a rainy day or a dryer, so that sand in the bunker can have cohesion, and sand is lost on the slope of the bunker. It is an object to provide a bunker seat and bunker structure for a golf course that can be prevented.

The bunker sheet of the present invention for achieving the above object is a golf course bunker sheet manufactured by using polyester fibers (Polyester Fiber), the bunker sheet has a density of 29 to 32 kg / ㎥, thickness (pressure 1kPa In) is characterized in that it is formed by curing and compression to 13 to 14 mm.

In addition, the bunker structure of the present invention, in the bunker structure of the golf course filled with sand therein, a drainage passage is formed in the bottom surface of the bunker to drain the water flowing into the bunker; and drainage of the bottom surface of the bunker To induce, the nonwoven fabric laid on the bottom surface to prevent the soil of the bottom surface is lost; It is formed by hardening and compressing a polyester fiber to have a density of 29 to 32 kg / m 3 and a thickness (at pressure 1 kPa) of 13 to 14 mm, to impart cohesion to the sand and to prevent loss. A bunker sheet laid on the nonwoven fabric; And a fine sand layer having a diameter of 0.1 to 0.3 mm and a thick sand layer having a thickness of 0.5 to 1.5 mm on the bunker sheet.

The golf course bunker seat of the above configuration can contain an appropriate amount of water without being greatly affected by the amount of water flowing into the bunker, so that the sand can have a constant cohesive force, the sand between the fine space of the bunker sheet Can be collected, in particular, it is possible to effectively prevent the sand of the inclined surface to flow to the center inside the bunker. In addition, the sand is prevented from being mixed with the soil of the bottom surface, and the bunker sheet itself has a cushioning force to absorb the shock from the upper side to prevent the sand from being broken.

The technical problem achieved by the present invention and the practice of the present invention will be more clearly understood by preferred embodiments of the present invention described below. The following examples are merely illustrated to illustrate the present invention and are not intended to limit the scope of the present invention.

2 is a detailed cross-sectional view showing the structure of a golf course bunker according to an embodiment of the present invention, Figure 3 is a cross-sectional view showing a detailed structure of the bunker sheet, Figure 4 is a flow chart showing a manufacturing process of a bunker sheet using a polyester fiber. .

Referring to FIG. 2, in the golf course bunker 1, the nonwoven fabric 30 is laid on the bottom surface 40 dug into a puddle shape, and the bunker sheet 20 is laid on the nonwoven fabric 30. The sand 10 is constructed on the bunker sheet 20. In the embodiment of the present invention, the sand 10 for the bunker is constructed of two different kinds of sand layers. In other words, the fine particles of sand 11 are first laid on the bunker sheet 20 and the thick particles 12 of sand are laid thereon. In addition, the bottom surface 40 is provided with a drain port 50 for draining the flowing water or rain water flowing into the bunker 1, as shown in FIG.

In general, the bottom of the golf course before the green or bunker is constructed, most of it is made of dirt, and the drainage is not smooth. Therefore, in order to build the bunker 1, the ground is dug and the drain hole 50 is first constructed, and then the nonwoven fabric 30 and the bunker sheet 20 are covered thereon, and the sand 10 is laid.

The nonwoven fabric 30 prevents the soil particles on the bottom surface 40 from being lost and prevents the soil particles from entering the empty space of the bunker sheet 20 and mixing with the sand 10. In addition, the nonwoven fabric 30 has excellent water permeability, and when water is introduced by the bunker sheet 20 on the upper side, the nonwoven fabric 30 can smoothly flow into the soil or the drain hole at the bottom thereof.

The bunker sheet 20 is a sheet for collecting sand from the upper side of the nonwoven fabric 30, and the bunker 1 is formed in a puddle in a puddle shape compared to a flat green, so that most of the bunker sheet 20 forms an inclined surface except for the center portion. . In this case, since the sand 10 of the inclined surface forms respective grains, the sand 10 flows into the center over time due to its characteristics. Bunk (1) in the golf course is to be spread evenly distributed on a surface with a uniform thickness of sand 10 can proceed to the game according to the original use.

To this end, the bunker sheet according to the embodiment of the present invention, as shown in Figure 3, to achieve a structure to minimize the sand loss, it is manufactured using a polyester fiber (Polyester Fiber). That is, the polyester fiber is processed into a wool shape, and then hardened and compressed again to prepare a bunker sheet.

The process of manufacturing the bunker sheet 20 is as shown in FIG. First, polyester fiber (polyester fiber), which is a main raw material of the nonwoven fabric, is mixed at an appropriate ratio (S1, Mixing process), and the mixed fibers are straightened as combing in an entangled state (S2, Carding process). By stacking the multiplied fibers alternately in multiple layers and stacking them in a nonwoven fabric form (S3, Cross Layer process), the sheeted fibers are bound to have a proper thickness and density (S4, Needle Punching process). . The resin is sprayed on the surface of the sheet to stabilize the first bound sheet (S5, Spray process), and the sheet, which has been subjected to the resin spray process, is impregnated in the resin tank to increase the binding force, and then taken out of the sheet. Penetration to increase the tensile strength (S6, Deeping process). The secondary-bound sheet is passed through a special oven to dry (S7, Dry process), and the bunker sheet is completed by cutting the finished sheet to a desired width and length (S8, Slitting and Winding process).

Looking at the cross-sectional structure of the bunker sheet thus produced with reference to Figure 3, the fiber yarn 21 of the polyester fiber is bound to each other, the fine space 22 is formed between the bound fiber yarn 21 as a whole sheet Will form.

In the bunker sheet 20 having such a structure, when the sand 10 is laid on the upper side, the fine particles of sand 11 flow into the empty space 22 between the fiber yarns 21 and the sand of the fine particles on the upper side ( 11) Some are mixed in layers with coarse grained sand 12, so that the entire layer of sand 10 can be collected by the sheet.

In addition, moisture is introduced into the space 22 between the fiber yarns 21 so that the bunker sheet 20 always contains an appropriate amount of moisture. That is, as shown in FIG. 2, when a large amount of water flows into the bunker or rains a lot (A), a predetermined amount is collected in the space 22 between the fiber yarns A1 and the remainder is permeated A2, so that the bunker sheet ( 20) can always maintain only a suitable amount of moisture (A1). The moisture (A1) affects the sand 10 on the upper side so that the sand 10 may have cohesive force with each other, and as a result, the sand 10 may not be easily lost even on the inclined surface of the bunker.

In addition, the bunker sheet 20 is a buffer structure of the space 22 between the polyester fiber fibers 21 and the fiber yarns, so that even if the player stepped on the sand or pressure is applied from above, The quality of the sand can last for a long time.

Here, the bunker sheet has a density of 29 to 32 kg / m 3, as shown in FIG. 3, and is preferably processed so that the thickness d becomes 13 to 14 mm under a pressurization pressure of 1 kPa.

When the density is smaller than 29 kg / m 3, the amount of water A1 or fine sand 11 flowing into the internal space 22 between the fiber yarns 21 becomes excessively large, and the water A1 is too easy. If there is a problem to escape, if the greater than 32 ㎏ / ㎥ is the amount of water (A1) or fine sand (11) flowing into the internal space 22 is too small, moisture (A1) is not easy to escape the problem There is this. In addition, when the thickness is thinner than 13 mm, the bunker sheet 20 may be easily broken. When the thickness is larger than 14 mm, the bunker sheet 20 may contain excessive moisture (A1), and the manufacturing cost may increase. Therefore, the bunker sheet 20 contains appropriate moisture A1 at a density of 29 to 32 kg / m 3 and a thickness of 13 to 14 mm (pressure of 1 kPa), so that sand loss on the inclined surface can be effectively prevented. .

Referring back to FIG. 2, sand 10 is laid on the upper side of the bunker sheet 20. In the embodiment of the present invention, fine sand 11 having relatively thin particles is laid first, and the particles are placed on the upper side thereof. Coarse grained sand for bunkers 12 is laid.

In general, it is called sand having a diameter of 0.02 to 2mm, in the embodiment of the present invention, the fine sand particles have a diameter of 0.1 to 0.3mm, the thick grain of sand is said to have a diameter of 0.5 to 1.5mm. In addition, the fine sand 11 is spread thinly on the bunker sheet 20 by about 5 to 10mm, and the coarse sand is relatively thick on 50mm or more.

Due to the structure of the bunker sheet 20, the fine sand 11, and the coarse sand 12 as described above, the sand in the bunker contains an appropriate amount of moisture even in a dry environment and is not easily lost by wind or inclined surfaces.

Although the present invention has been described with reference to each embodiment shown in the drawings, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
