At the end of the last box, there is a one-sided or double-sided water collecting cap installed, and another box can be attached to the cap in the same or opposite direction, increasing the length of the drainage by another section.

Description

Case for cascading drainage, drainage and storage of water and method of its use

The field of technology to which the invention relates

The invention relates to a box and a cascade system for the management of rainwater intended for draining, removing and storing rainwater. This system is called SKORM.

A very important element influencing the condition of foundations, paved areas, roads and sidewalks, green areas, sports fields is quick and effective drainage of water during rain.

The task of a good and effective drainage system is to remove as quickly and completely as possible the discharge of rainwater into the reservoir, as well as the water penetrating into the structure of the buildings and the structure of the pavement due to the capillary expansion from ground water.

The basic function of the SKORM system is the rapid and effective collection and discharge of precipitation water to protect foundations and areas hardened by an innovative system of cascade gutters.

The SKORM box system is also useful for draining rainwater. Thanks to the rain- watering boxes, rainwater harvested from the hardened land is drained below it.

The SKORM system can also be used to store water, especially rainwater. State of the art

In traditional methods of drainage pipes and stones placed in ground are used for creating the space for storage and remove rainwater and other water, for example ground water.

Also known are drainage systems consisting of crates. These systems are easily silted, resulting in reduced productivity and even a complete malfunction of the drainage system. In the case of the traditional method, the effectiveness of draining does not exceed 20% as the water penetrating the stones is drained away only in the part that is directly above the drainage pipe and penetrates into the interior, while the remaining 80% of the water flows along the pipe, breaking in the ground. Due to the fact that the drainage pipe represents only 15% of the volume of the drainage system, the traditional system, due to low efficiency, mainly serves the function of the drainage system. In the case of a traditional system, only drainage pipes can be inspected and cleaned, while the free space between the stones completely clogs the accumulated sediment, reducing the flow of water, and after several years there is a need to remove the stones, mud wash and repositioning of the drainage.

Subject matter of the invention

The basic element of the system according to the invention is an openwork box with a cascade of gutters for draining water located in the ground. Such a single element, depending on needs, is connected horizontally or vertically with clamps in a larger set to form a complete drainage, drainage and storage system, especially rainwater and groundwater.

An important element for the proper functioning of the box is the preparation of the excavation bottom, which must be precisely aligned without large stones and clods to ensure uniform support of the crates throughout their length. In order for a box set to function properly, it must be wrapped around the water-permeable geotextile on all sides. In the case of water storage, the box should be wrapped with a heat seal foil.

The S ORM box has a rectangular shape with dimensions of preferably 50x30x100 cm and four large openings with openings for easy water penetration. Reinforcements inside the box and lattice construction of the walls ensure high strength. In the inside of the box, a box- shaped gutter and a 3 ⁰ inclined plane are mounted parallel to each other. At one end of the box at the outlet, the falling gutters protrude beyond 2 cm to make it easier to extend the gutter system by connecting the next box to form a cascade system. Through subsequent boxes to the storage tank or water splash tank. Thanks to its modular design and easy connection with the latches, the box connects in series in any length of the segment, fulfilling the basic function of the SKORM system, creating a system that efficiently collects and discharges water. At the end of the system or in any place, a full-walled cap drains the collected water to the downpipe. By stacking boxes horizontally or vertically, they can perform two additional functions as a water drainage and storage system.

The principle of operation of the SKORM system is to create in the drainage of free space thanks to the frame structure of the box to which rainwater is filtered, and then through the cascade system of arranged gutters is discharged to the retention tank, river or other device or object intended for storage or discharge of water. The upper gutter in the box serves to take over most of the rainwater that penetrates the inside of the box. The other gutters installed in the cascade serve mainly to convey the collected water to the subsequent crates, and additionally to drain the water seeping through the side walls of the crate.

In the system according to the invention, the size of the boxes and thus their capacity and the number of applied gutters were adjusted in terms of efficiency in the acceptance of water for all categories of land from I-V. The solutions applied to the size of the boxes and the number of gutters used are also largely due to the purely economic account. In the box of the SKORM system gutters are installed, preferably in 12 gutters, so it is possible to connect in a line to 12 boxes ensuring water flow in one direction, at the end of the box 12, one-sided or double-sided water collector should be installed. You can attach another 12 boxes with a drop in the same or opposite direction to increase the drainage length by another section.

Thanks to the skeleton box construction, the capacity and efficiency of the SKORM system in the collection of rainwater from the ground is 8 times that of the traditional system. The dimensions and volume of the SKORM boxes correspond to the size and volume of the traditional stone drainage method as a water storage space, however, despite similar sizes of two systems, the SKORM box capacity is 150 1 while the identical size of the traditional stone system has a capacity of only 15 liters. The stones occupy 90% of the volume. Installed in the SKORM boxes the gutter system drains 100% of the rainwater penetrating into it. In the ease of the traditional method, the effectiveness does not exceed 20% as the water penetrating the stones is drained away only in the pait that is directly above the drainage pipe and penetrates into the interior, while the remaining 80% of the water flows along the pipe, breaking in the ground. Due to the fact that the drainage pipe represents only 15% of the volume of the drainage system, the traditional system, due to low efficiency, mainly serves the function of the drainage system.

In the SKORM system it is possible to inspect and rinse the whole drainage system from the sludge by guaranteeing a 50% lifetime of the boxes 100% efficiency. In the case of a traditional system, only drainage pipes can be inspected and cleaned, while the free space between the stones completely clogs the accumulated sediment, reducing the flow of water, and after several years there is a need to remove the stones, mud wash and repositioning of the drainage.

Positive effects of the invention with respect to the prior art

Using the SKORM system as a rainwater splash box is recommended because of ecological reasons, as it prevents the groundwater level from falling, and rainwater penetrates deeper layers of the soil to restore and increase groundwater resources. The SCORM system of the invention contributes to the protection of surface and groundwater resources.

The SCORM system of the invention provides greater capacity and efficiency of the box in the reception of rainwater from the ground, which is 8 times greater than that of the traditional stone drainage system. The benefits of the SCORM system:

- Warranty 50 years of high 100% efficiency,

- A large active drainage area of 100% of the box volume,

- Large active water storage area of 100% of the box volume.

Drawings

Embodiment of the invention The cascading dehydration box shown in Figure 1 is designed for draining and storing water. There are 12 gutters in the box. The box is located in the ground around the building. The box is connected in line as shown in Figures 2 to 12 boxes, ensuring the water flow in one direction. At the end of the box 12 is a one-sided or double-sided water collecting unit. A further 12 crate boxes are attached to the overlap in the same or opposite direction, increasing the length of dehydration by another section.
