JPH0576619A - Method for removing harmful matter in earth of the like - Google Patents

Abstract

PURPOSE:To realize treatment without business suspension in the case of the above method for removing harmful matters in earth or the like at a golf course or the like by digging vertical holes into earth with intervals provided, filling an adsorbent into these, covering the surface layer portion with earth, and putting turf over it. CONSTITUTION:Earth is dug by means of a screw auger or the like, and vertical holes 1 are provided zigzag at appropriate intervals. And, one or more than two kinds of an adsorbent 2 such as activated charcoals, bone materials or the like are filled into vertical holes 1, and pounded and hardened. Next, a surface layer portion is covered with earth 3 and then with turf 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a method for removing harmful substances such as pesticides in the green of a golf course or in a pond.

[0002]

2. Description of the Related Art Conventionally, fairways on golf courses and grass on the green part are covered with activated carbon, aggregate, charcoal, ion-exchange resin, etc. to remove harmful substances such as pesticides, and covered with dirt and turf. Construction methods such as stretching were used. If it is a new golf course, the construction is not so difficult, but especially in the case of an existing golf course, it is necessary to peel off all the grass and replace it, and it took a long time. Especially at the one-green golf course, I had to take a break during that time.

[0003]

The present invention has completed the present invention as a result of various researches on methods for improving these conventional construction methods.

[0004]

According to the present invention, vertical holes are provided in fairways and greens, and activated carbon, aggregate, charcoal, ion exchange resin, etc. are filled therein with one or two or more kinds of soil, and soil is then added. It is a method of covering and covering the grass with it.

The present invention will now be described with reference to the drawings, but the present invention is not limited to the following description. First, as shown in FIG. 1, the vertical hole 1 is formed by excavating the soil with a screw auger or the like. The diameter of this vertical hole is 150m
About m to 300 mm is preferable. The vertical hole depth is 50
About 0 mm is preferable.

The vertical holes 1 are preferably excavated at appropriate intervals. For example, various shapes such as staggered vertical holes 1 can be adopted. The vertical hole 1 is filled with one or more kinds of adsorbents 2 such as activated carbon, aggregate, charcoal, ion exchange resin, etc., and after firmly sticking, cover the surface layer with soil 3 and cut out on it. It is completed by stretching the turf 4.

As another embodiment, a cylindrical tube having a hole for entering the vertical hole 1 may be preliminarily filled with the adsorbent 2 and prepared, and the whole cylinder may be inserted into the vertical hole 1. As another method, a method of inserting a cylindrical net bag filled with an adsorbent into the vertical hole 1 is also adopted.

According to the method of the present invention, a vertical hole 1 is further provided around the pond in the same manner as described above, and if an adsorbent is filled, harmful substances such as pesticides flowing into the pond can be removed. Furthermore, in the pond, a cylindrical cylinder with holes as described above, or a cylindrical net bag is floated to hang it down, or if a heavy drip is attached to the bottom to float it, the wall surface and contact surface will be increased in the pond and harmful substances will be removed can do. The device may not be visible on the surface of the water, or grass or trees may be planted.

[0009]

According to the method of the present invention, the construction is simple,
In addition, it can be said that it is an extremely advantageous construction method because it can be installed on an existing golf course without taking holidays.
