Definitions

  • the present invention relates to the golf courses field and in particular it relates to a method for the construction of a golf course "bunker”.
  • the invention also relates to a golf course bunker obtained by the aforementioned method.
  • the bunkers are obstacles provided in a golf course which can have a size, a shape and can be present in a number which differs from course to course. Normally, the bunkers can have a surface which goes from about 25 m 2 to a size of several hundred square metres. A single golf hole can have no bunker, or can have more than 20 bunkers.
  • a bunker forms a depression more or less accentuated with respect to the neighbouring land and is usually provided with a covering layer of sand.
  • the bunker can have a covering layer of different type, for example a layer of gravel, or another inert material, or can be provided with a covering layer of grass.
  • the bunkers are placed along the golf path, on the courses, and near the green, and mainly have the aim of increasing the difficulty of the game for the golfers, because when the ball falls within this obstacle is more difficult to, and is necessary to use special golf clubs and to hit the ball with a technique which is not always easy to perform.
  • the golf rules provide that a ball fallen into a bunker must be played within the bunker same, because this is an integral part of the course. For this reason, it is of fundamental importance that they are kept in perfect efficiency. Therefore, it is fundamental that the edges of the bunker are always well defined, that there the drainage is always fully functional and that the sand, or the gravel, is always raked and cleaned, in order to guarantee that the same is free of weeds and waste of different type such as stones, mud and other material which could compromise the stroke of the golfer or the correct functioning of the bunker same, for example due to an obstruction, or compromising the drainage capacity. It is not a coincidence that the correct maintenance of these particular surfaces is among the most difficult to carry out.
  • the research is oriented to identify systems which allow to rationalise the management of the same.
  • an underlying layer is present in a determined material.
  • a layer of cement normally a drainage cement.
  • the cement in addition to have a high hardness, has also a structural limit which makes it necessary to construct underlying layers with thickness greater than 50 mm or even more.
  • a drawback of the prior art bunkers is that many golfers, in the attempt to bring the ball out from the bunker, can hit the underlying layer or a big stone, or the layer of cement, or simply a compact layer of soil, especially in the case of covering layer with a small thickness, and to suffer a backlash which, in addition to damaging the head of the golf club, can also cause trauma to the player's wrist.
  • the bunker can widen and the sand, or another material which forms the covering layer, can be dragged away and is, therefore, necessary to restore the same with new material, with great waste of time, energies and money.
  • a further drawback of the golf course bunkers of prior art with an underlying layer of cement is the difficulty of dismantling the same, for example, if the Company managing the plant wishes to change the path by modifying one or more holes.
  • an object of the present invention to provide a method for the construction of golf course bunkers that is able to overcome the aforementioned drawbacks of the prior art bunkers.
