Description

Technical field

The technical solution relates to a method of solving a hydrological device for capturing and using rainwater from roofs for fire purposes. Rainwater from buildings is usually drained from roofs and paved areas through internal or external rainwater drains into external sewers or terrain. This solution does not use the potential of rainwater. The proposed hydrological device for the capture and use of rainwater from sloping roofs represents a comprehensive system for the treatment of rainwater, their capture and accumulation, condition monitoring and use specifically for fire purposes ·

It is used in the field of protection of buildings against fires, in the protection of the environment and in the creation of intelligent management and water management systems. The set for the use of rainwater can be used not only for new constructions, but also for reconstructions and renovations of buildings.

Prior art

Water is becoming a strategic raw material and its optimal use is becoming increasingly important. It is also related to climate change, which in our climate zone causes uneven total precipitation, heavy rainstorms or. drought, which is reflected in low river flows and low groundwater levels. Thus, the accumulation of water and its use during the period without total precipitation becomes important. Therefore, it is necessary that water, according to its nature, be used efficiently, which applies to rainwater, which has great potential for use. The current state of water management indicates that rainwater is drained from the roof areas by external downpipes to the terrain or inner downpipes into the vertical and subsequently horizontal sewers and drains to the recipient. Thus, a lot of rainwater flows into the river basins without being used. Industrial companies can then capture and use this water from the river basin, or use drinking water from the pipeline system. In general, drinking water is used for fire-fighting purposes, for distribution in sanitary facilities (toilets) and for various technological purposes, or for cleaning and irrigating premises. This solution is uneconomical because it does not use available rainwater. Recently, in new constructions, the capture of rainwater has been solved according to the requirements of sewerage administrators by solving storage rain tanks. Water tanks are based on underground reinforced concrete tanks, metal structures, but very preferred are based on hardened plastics or. composites. Rainwater harvesting solutions are offered for single-family homes, and adequate solutions for industrial buildings are not yet available. Abroad, saving on water and sewage systems is a very widespread and common element of saving, in Slovenia, for example, 90% of new single-family homes are handed over to rain tanks, and these systems are also subsidized in some countries.

The use of rainwater is suitable from roofs with ceramic roofing, concrete, enamel, metal or plastic and foil roof, as the water remains relatively clean and soft. Water pollution is only organic impurities blown by the wind It is not recommended to collect water from green roofs and from asphalt roof surfaces, as humusoid parts leach out and the water is usually acidic. Rainwater tends to be acidic water also because the water contains dissolved CO2, which it absorbs when flying through the atmosphere. In the summer months, rainwater can be sporadically smelled by sensitive people or can cause poor sedimentation. If rainwater is used in toilets, the mentioned deposits can visually interfere (the solution is a different color of sanitation - not bright white). But this is a problem of quality mechanical filtration.

If rainwater is fed from the roof directly to the underground tank and stored there in the dark, it maintains a consistently high quality and organic reactions do not take place there. Rainwater from paved parking lots and roads is not suitable due to possible oil impurities to mix with water from roofs, therefore the subject of the solution will be only the use of water from roofs.

The use of water for fire purposes is determined by Decree 699/2004 Coll. - Decree of the Ministry of the Interior of the Slovak Republic of 10 December 2004 on the provision of fire-fighting structures. Fire water could therefore be used in fire water tanks and from there in the distribution of external and internal fire water supply. Possible use would also be in water distribution to water stable fire extinguishing equipment (sprinklers, drenchers) in accordance with Decree 169/2006 Coll., Decree of the Ministry of the Interior on specific properties of stable fire extinguishing equipment and semi-stable fire extinguishing equipment and on conditions of their operation and ensuring their regular controls.

The essence of the technical solution

The essence of the hydrological device for the capture and use of rainwater from sloping roofs for fire purposes in buildings is a common system of drainage of rainwater from roofs through external rain gutters (gutters, waste pipes). The rain gutter is equipped with a roof raft catcher at the point of contact with the terrain

S K 8301 Y1 nín. Behind this catcher there is a filter for catching fine dirt. Through the supply pipe, the water then flows by gravity into the underground storage tank - fire water storage tank, while the inflow in the lower part of the tank flows through a pipe with a rounding to ensure a whirling inlet and circulation of water. The fire water tank is stored at a non-freezing depth under the ground and is also accessible via an inspection shaft with a cover. This input is also required for maintenance, monitoring of the fire water level and direct connection of fire equipment via suction accessories. For this purpose, an access road to the fire water tank must be built with a paved area for fire trucks. In the upper part of the tank there is an overflow drain in the slope into the drain blocks. Drenblok is a device for smooth and natural infiltration of rainwater into the ground. The system is based on the chamber principle, which on the one hand allows to handle any amount of rainwater and on the other hand eliminates clogging and non-functioning of the system. There is a sensor in the fire water tank to determine the water level, which transmits the information to the personal computer. Monitoring of the quantitative state (level) of rainwater also serves for a critical state, when the loss of water would make it impossible for its functional use, therefore it is necessary to connect systems using fire water to the public distribution of drinking water (backup source).

From the fire water tank, water is taken through a piping system to an automatic pressure station (with a backup pump and also with a backup source of electricity) in the building, from where it branches into the fire water supply with outlets to indoor and outdoor hydrants and stable fire extinguishing systems (sprinklers). , drenchers, etc.). Dimensioning of the need for fire water and the mentioned partial technical equipment is necessary according to the relevant STN, which makes it possible to connect fire water tanks with several rain gutters or, if necessary, to dimension several tanks.
