Description

[Detailed description of the invention] Easily solidifies by compaction, requires appropriate hardness, repels water such as rainwater, prevents weeds from growing, and is colored. It is used for land that is desired to have a pleasant appearance, for example, for sports courts such as tennis courts and volleyball courts, or for paving soil such as park pavements.

Natural Oil Sand (trade name) is known as a paving soil with the above-mentioned functions. This natural oil sand is earth and sand containing heavy oil that is naturally produced near oil wells in the Akita and Niigata regions, which are oil fields in Japan. Masa soil from the Kansai region is mixed and laid and compacted on the target ground to obtain sports courts such as tennis courts that have the above functions.

The natural oil sands are generally a mixture of 90-93% earth and sand, 7% heavy oil and 0-39-6 organic complexes. The above-mentioned organic complex is a substance produced by the reaction of clay minerals and heavy oil, and the presence of this organic complex gives paving soil easy solidification, the necessary hardness, and repellency. It brings water-based properties.

The present invention utilizes the heavy oil sludge containing the waste oil that is deposited at the bottom of the oil tank, which is generated when cleaning the oil tank, which is currently left over from the oil tank. Artificially made oil sand to replace sand
Furthermore, it is intended to provide soil that is designed to maintain a stable color against rainfall and watering by coloring tennis courts and the like that are constructed with this in a color that is suitable for use.

The main ingredients are earth and sand, heavy oil, an organic composite produced from clay minerals and heavy oil, cement and a cement-based solidifying agent, and mixed with earth and sand to which pigments such as metal oxides are added. It provides an alternative to natural oil sands with a desirable color.

Last month - The clay minerals contained in the soil are reacted with heavy oil to artificially produce an organic complex, and the presence of this organic complex provides the easy solidification required for paving soil equivalent to natural oil sand. It is colored in such a way that it provides the necessary hardness and water repellency, and also maintains a stable color even under rainfall and water spraying, giving it a desirable color feel.

1. The manufacturing procedure for this colored paving soil will be explained using the attached flow sheet. First, heavy oil such as oil sludge deposited in an oil tank is mixed with earth and sand containing clay minerals to form an organic complex, and cement and a cement-based solidifying agent are added to this mixture. Water is added to the clay and mixed with a mortar mixer, pigments such as metal oxides are added to the clay, and if necessary, clay material is added and mixed again to form a solidified material. This training period is 3 in the summer.
~7 days, 7 to 14 days in spring/autumn, 10 to 45 days in winter (
(adjust the length depending on the temperature). This semi-solidified material is roughly crushed using a crushing press, then crushed using a crusher, and then sieved with 5-self-restraint, and coarse particles are crushed again and the bottom of the sieve is replaced with the above-mentioned natural oil sand. Use artificial paving soil.

The composition ratio of the components of the paving soil according to the present invention is as follows.

Sediment 30-50% Heavy oil 10-20% Organic complex 2-4% Cement 15-25% Cement solidifying agent 4-8% Pigment-colored earth and sand 5-20% The oil content of this paving soil is 10-20%. is the best, but
A mixture of 15 to 30% of this soil and 70 to 85% of high-quality soil for tennis footing, such as masa soil, is poured onto the ground that has been leveled in advance as a tennis court site.
If it is laid to a thickness of a1 and then rolled, the desired tennis court will be created.

The tennis court obtained in this way has a firm surface and good tennis playing conditions even though it is an earthen court, and since it is an earthen court it has an appropriate amount of slippage.
It is less likely to hurt the players' legs and back, and since it contains oil, it drains from the surface when it rains and dries quickly, making it an all-weather court, making it more efficient to use. There is little difference in the degree of color when wet and dry, and the red and green colors that are particularly popular for tennis courts are stable because they are made of metal oxides such as gray and chromium oxide. In addition, since the moisture content is low, there is no risk of damage due to frost pillars, and a good coat is created that does not allow weeds to grow. In addition, as mentioned above (in construction, it is possible to create an artificial substitute for natural oil sand, which saves transportation costs, and oil sludge from heavy oil tanks that require waste acid can be used as an effective raw material. It is also effective from the viewpoint of protection, and its use is wide, not only for tennis courts with candles but also for various sports courts, sidewalks in parks, outdoor areas of ordinary households, etc.
In addition, after compacting the ground, it can be easily repaired by scraping up the parts that have worn out, adding new paving soil with the above-mentioned composition, and drying it again, as it will harden easily. There are some advantages to doing so.

In addition, as mentioned above, the raw materials such as earth, sand, and oil are materials that are easy to work with and are inexpensive throughout the country, and are useful for making excellent athletic courts that are not only cheap to construct, but also require little effort on daily maintenance. I'll give you something
