Description

Technical field

Technical solutions of this type are widely used wherever there is a sufficient or surplus of water and other liquid substances. At this time and I expect in the next period, the protection of life and property against the water element will be very topical. It is therefore a flood barrier or a barrier against another liquid substance such as e.g. oil, contaminated liquids, etc. It can be used in water management to quickly raise river banks, artificial and natural canals, dams or ponds and prevent water flow and disrupt some parts of water structures. We can also prevent water from entering certain places with this system, diverting water from places where it would do a lot of damage, such as houses, farmland, forest stands, industrial zones, chemical and petrochemical plants, etc. The system can also be used as a water reservoir during drought in hard-to-reach places in forests, parks or during harvesting, etc.

BACKGROUND OF THE INVENTION

At the outset, we can say that the current state of protection against water is insufficient, as evidenced by the increasing and greater damage caused by the water element. Any new water protection system can only increase safety and water element protection. Existing systems are very laborious and time-consuming to build or install, such as. sand-filled bellows, various fiberglass or metal barriers mounted in various stands and supporting structures. Some solutions are sometimes at the expense of aesthetics and can not be canceled or moved in a short time.

The essence of the technical solution

The proposed solution eliminates the disadvantages of the prior art. The main principle of this system is to provide bags that can be joined and into which water or liquid can be impregnated mainly by means of pumping technology. We take into account the fact that we have enough water, because we will build such flood barriers mainly at watercourses or water structures. We also take into account that pumping and compression technology will greatly accelerate the filling of these bags. The flood barrier will be constructed as a bag in a bag. The outer bag will be filled with water or other liquid, and the inner bag will be filled with compressed air, gas or even pressurized liquid. The bags can have different lengths, different diameters, also shapes and hence different heights when filling. The bags may be partitioned inside by baffles to help us maintain the desired shape and stability when filled with liquid. The bags can only be filled with liquid up to a certain volume and then inflated to a certain pressure with air or gas. Because of the solubility of air or gas in water or other liquid and thus the possible reduction of bag pressure, the flood barrier will be constructed as a “bag in bag”. The inner bag will serve as a flood barrier bag stabilizer and also as a pressure compensator. The bags will be strong enough, but at the same time flexible enough to follow the terrain and some natural irregularities. They can be made for universal use with a certain length and max. possible internal pressure. They can also be made for special applications e.g. for direct flows, flows with a certain radius, gradient or with the possibility of directly connecting the beginning of the bag to its end and forming a barrier e.g. around the building and so on. We assume that the water has a weight of 1000 kg / 1 m ³ and a column of water 10 m high creates a pressure of 1 atm. These bags are essentially flexible, sufficiently rigid, structurally stable, closable pipes of a certain length that can be joined. These bags will be filled with water, other liquid, compressed air or gas mainly by means of pumping and compression technology with sufficient flow capacity and pressure. The bags will be impermeable to water and air, so if these bags are filled with water or liquid and closed, we can increase the pressure of the bag to the permissible value with the help of air or gas pressure to achieve a constructional shape. . It depends on how much liquid (eg water) and gas pressure (eg air) will be in each bag. Also these bags can be reinforced with various strings, pressure hoses into which we inflate the air pressure and the like. Coupling these bags can be in different ways. We can connect them eg. Velcro fasteners or special couplings resistant to water and other liquid substances. The edges of the bags are made of sufficiently flexible material, so they form a sufficiently tight joint when the bags are connected and filled. If necessary, you can place a pad under the bag and attach it to the bag. If these flood barriers are to be abolished, the water or other liquid substance is simply drained and, after drying and preserving, is folded and stored at a designated site, or will be disposable and recycled immediately after use.

Example

The flood barrier 1 consists of a bag 2 made of PVC tarpaulins with water and air tightly bonded. The diameter of the bag 2 is 1000 mm and the total length is 4000 mm at the edges is closed from the same material. The bag 2 is made to a maximum internal pressure of 1 atm. The bag 2 houses a stabilizing and compensating bag 13 which, with the help of baffles and centering bands 14, is mounted in the interior of the bag 2 with a diameter of 300 mm and a length of 4000 mm made of PVC canvas. The stabilization and compensating bag 13 has a valve 15 on the outside of the bag 2 adapted to receive compressed air, gas or liquid. The flood barrier is always laid flat with a defined maximum longitudinal slope. This is due to not exceeding the maximum design internal pressure and thus the structural strength and also to prevent spontaneous movement against slipping (wet terrain is always more slippery than dry). The bag in the filled state is not adapted for carrying due to its high weight (1m cubic water has a weight of 1 ton !!!). The bag is always placed on a plane or slope with a limited longitudinal and lateral inclination. All the seams of the bag 2 are covered with tapes 3 for increased tightness of the seams and increased strength of the bag 2. On the inner circumference of the bag 2 there are glued spring clips 4 into which the plastic string 5 is attached.

2. For joining the bags 2, Velcro fastening systems 6 are attached to the edges. The second part of the hook-and-loop fastener 7 is part of the flood barrier 1. Around the circumference of the bag 2, various auxiliary fastening parts 8 of the hook-on fastener and the auxiliary fastening eyes 9 are glued, which have a stabilizing and anchoring function. A pad 16 is inserted underneath the bag 2 if necessary, which is attached to the bag by means of a Velcro 8 and ancillary eyes 9. The pad serves to prevent possible mechanical damage to the bottom of the bag 2 and to seal off any unevenness under the bag 2 or reduce 2. Threaded inlet and outlet openings 10 having a sufficient size for the inlet and outlet of water or other liquid, mainly by means of pumping equipment, are fastened to the bag 2 and are tightly sealable by plugs 11 into which the valve 12 can be fitted. increasing the internal pressure in bag 2 by means of compressed air, gas or liquid and other auxiliary equipment (eg a pressure gauge, a thermometer, a venting valve, etc.).

Industrial usability

Flood barrier has a great possibility to use mainly in the field of civil protection and water management. It can be used wherever we need to prevent the direct flow of water to objects, land, forests, roads, etc., also where we need to divert the water flow and create an "artificial" trough for running water. With this flood barrier we can artificially raise the bank of a river or water structures such as. dams of ponds, dams and the like. Because this flood barrier is designed to fill with water and other liquid substances, it can be used for water supply in fields, in forests in the event of a possible fire, but also as a supply of drinking water for people or animals. In the event of an accident, we can store various liquids such as petroleum products, liquid wastes and so on.
