Abstract

The sealing element is in the form of a stone which has the external form of one or more connected individual stones of all existing paving stone types and consists of concrete or other permanently rigid materials. Through the arrangement of several water inlet opening rows one behind the other and which next to each two dirt collection channels have several water inlet openings on the raised middle wall, the paving stone insert can also undertake the function of a dirt collection grill.

Description

Components

The collector consists of three main parts:

• 1. the paving stone
• 2. the collector with hose connection sleeves and seal
• 3. the trickle part with delay tract, check valve and frost damage protection

tasks

The collector has the following tasks:

• a) by retrofitting or initial installation in all possible surface seals or fixings such as pavement, paved and concrete surfaces or troughs on streets and squares, all or all of the surface water accumulating
  • - let it flow
  • - to record
  • - collect in the sprinkling section
  • - direct to a definable point
  • - Feed the water-unsaturated soil below the surface for trickling
  • - to avoid an increase in the water below the sealing material such as paving stones etc. by the built-in check valve and thus to prevent undermining.
• b) by the diverse forms of the paving stone, which in its form four coherent of all patterns and colors available on the market
  • - natural stone paving stones
  • - concrete paving stones
  • - All other fastening and sealing materials such as concrete, tar etc. accordingly
• is produced, harmoniously in all conceivable surface seals and fastenings without major modifications integrate quickly, easily and harmoniously to let.
• c) to ventilate the floor more than before
• d) with a correspondingly large installation area as a surface fountain and possibly as a sprinkling option for other surface waters such as roof drainage etc. to serve.
• e) through its mode of operation the drainage systems such as
  • - pipelines
  • - sewage treatment plants
  • - Channels
  • - to relieve rivers
• so that flood conditions to the extent experienced so far be prevented.

The parts 1. The paving stone

The paving stone has the outer shape of four contiguous Paving stones, two stones next to each other and one behind the other were ordered. Other dimensions such as 3 × 3, 2 × 3 or 3 × 4 Stones etc. are also possible. All on the market:

• - Shapes (such as double T, honeycomb shape, old town, rectangle, square etc.)
• - Colors (red, black, concrete colors etc.) on composite paving stones as well
• - natural paving stones
• - Black blanket
• - concrete surface
• - other surface sealing materials and agents

are the basis for the external, dimensional (length, width and height) and Colored shape of the paving stone, in order to the most diverse Surface seals can be integrated harmoniously.

Rectangular paving stones are used for universal integrations made in the usual measurement systems such as 5 × 10, 6 × 12, 7 × 14 and not relevant seals can be integrated, or in all composite plaster patterns can be integrated into a curb frame are.

Basically, this part is made of concrete, but all are permanently solid materials can also be used.

Each row of paving stone must have rows of water inlets along the entire length so that the entire incoming surface water can flow in without already part of this water can immediately flow past the row of collectors. This Rows of collectors can run in the longitudinal or transverse path over the whole stone. The water inlet openings of 10 mm in diameter have at their Bottom end water trailing edges, so that the water is completely direct can be given to the collector without any adhesions to overcome that could misdirect the water. Through the Arrangement of several rows of water inlet openings one after the other in addition to two dirt trap grooves, several water inlet openings of 10 mm The paving stone can have a diameter on the raised central web also take on the function of a dirt trap grille. Because incoming dirt particles are held in the dirt traps and cannot flow in through the water inlet openings.

Dirt particles up to 10 mm in diameter can easily pass through all Components flow without causing blockages anywhere.  

Furthermore, the paving stone is able to withstand the same pressure endure like the normal paving stones of the corresponding pattern.

2. The collector with hose connection sleeves and double U-seal

The collector with hose connection sleeves is in its length and width depending on the paving stone. It must be dimensioned so that its upper inlet opening is larger than the extent of the water inlet openings in the paving stone, so that all the incoming water from Collector can be included. The collector is otherwise universal usable and not tied to a specific pattern of the paving stone. In addition to the outer frame, the collector is in the inlet opening reinforced with cross and longitudinal struts so that the paving stone a there is enough firm support so that it does not break under the load. The cross and longitudinal struts should not be below the water inlet openings of the paving stone. If the course under one Water inlet opening is inevitable, the strut and the seal on the Cut out the contact point with the water inlet opening in depth a continuation of the water between the two parts is avoided. To seal off the water inlet is between paving stone and Collector has a double U-seal attached over the outer Frame and struts of the collector stretches.

At the bottom of the collector there are one, two or more hose connection sleeves attached, through which the collected water in the sprinkling parts can flow. In these outlet openings there is a smoother inside Cone incorporated to hold a sealing ball and if necessary the to be able to stop another water outlet, so that in the event of a backflow of the Water in the trickle part of the water level can be kept so low can that an undermining of the substructure of the surface sealing is impossible.

The outside dimension of the hose connection sleeve corresponds to the inside dimension of the Sprinkling part that is attached to this sleeve without a seal.

Basically, this part is made of concrete, but all are permanent solid materials can also be used.

3. The trickle part with delay tract, check valve and Frost damage protection

For reasons of assembly, this part is basically cylindrical and flexible. However, other shapes and materials can also be used. Basically, this part consists of a commercially available drainage hose made of PVC with the largest possible dimensions in length and diameter, around the largest possible storage volume for the incoming and to provide water to be sprinkled. Basically, at the submitted version of the component two tubes with a diameter of 160 mm connected to the collector and offer at one Length of 50 cm a minimum total storage volume of 20 liters.

To prevent any frost damage that could occur as a result,  that the water in the collector and not yet seeped in freezes and bursts the hose is in the middle of the sprinkling part full length wooden stick introduced. This wooden stick is held by a pen, which is about 10 cm below the upper end of the Sprinkling part runs across the hose and at the same time the Support for the sealing ball, which after the water rises floats above and if necessary closes the check valve to To prevent washing the substructure.

The incoming water first passes through the lower end opening of the Hose and trickles into the ground. Should the sprinkling amount smaller than that of the incoming water, the water in the Collect delay tract and also through the peripheral perforation of the tube seep away. This can take so long until the surface is saturated is that the inflowing amount of water is constantly increasing seeping away, and the water level in the delay tract rises until the Sealing ball on the water surface the check valve to the collector closes. Then no more water is released for trickling to to prevent further rising of the water level.

The diameter of the sealing ball is at least 30 mm smaller than the inner diameter of the sprinkling part, so that dirt particles from 10 mm diameter can flow through easily.

Rise the water in the unsaturated area of the soil to below the Paving stones on, there would be the danger that in the underground influx the substructure of the pavement would be washed away with the water to the receiving water and so caused damage.

Impact

The component described here can also be retrofitted in new buildings all existing surface seals are installed and used previously unused soil areas for trickling surface water. This will:

• 1. The surface runoff of the water that is on the sealed surfaces forms, almost completely eliminated;
• 2. via the underground way of saturating previously unused water storage potentials total discharge in soil reduced;
• 3. the reduced total flow rate only over the delayed route of derived underground feed to the receiving water;
• 4. the existing drainage systems such as piping systems etc. as well as rivers and currents significantly relieved;
• 5. on the increased use of the natural cleanability of the floor improves water quality for free;
• 6. created the basis for smaller sewage treatment plants to be built in the future dimension;
• 7. Improved ecosystem and climate, above the increased air and Water exchange with the soil;
• 8. with a minimum total storage volume of 20 liters per collector, a maximum amount of rain of 9 liters per square meter in 15 minutes and an average measured sprinkling speed of 1.5 liters  per minute and trickle collector from each sprinkler the water one Area of at least 2.5 square meters completely included in one Installation at a distance of 5 meters perpendicular to the flow direction of the water;
• 9. with a minimum total storage volume of 2 cubic meters per 100 square meters of area to be drained Area fountain for other surface waters (such as Roof drainage etc.) created;
• 10. Flood conditions to the extent that were caused by the increased, rapid surface runoff were avoided.

Installation

During initial installation and subsequent installation of the trickle collector are in the compacted subsurface using the assembly tool of a hydropneumatic hammer drill pressed into the ground and the soil holes must be cleaned several times from the absorbed soil manufactured, in which the sprinkler hose is then inserted can be. Then the hose is shortened accordingly, the frost damage protection inserted, sealing ball added and the collector with Seal placed on the hoses and the prepared sand bed. Since the Hose is also flexible in length, can be any compressions due to a hose that is too long, can be picked up easily. Then can put the seal and the paving stone and later through a compressor to the correct installation height.

Counteracting possible interference

In order to maintain the functionality of the trickle collector, it is necessary that the water intake is not due to any blockages is impaired or inhibited. This problem is as follows encountered:

To have a sufficient storage volume for the surface water to provide to keep the water path as short as possible and contamination on the way between the point of impact and the inlet The sprinkling series are kept as low as possible in the previous calculated distances from each other built into the sealed surfaces, so that the required amount of sprinkling is achieved. Because the paving stone also performs the function of a grille and only Dirt particles of at most 10 mm in diameter, the then flow easily through the entire trickle collector can settle on the ground and are still permeable to water there sufficient prevention of constipation.

Possible frost damage is due to the frost damage protection already described prevented in the sprinkling part.

When using the freezer in street drainage, so that instead of the previous side gutters with drain gullies the trickle would be installed,  a cleaning of the water would be necessary. That could be in the form be realized that in the collector instead of the struts in front of the hose connection sleeves an oil separator or the like would be integrated.  

Critique of the state of the art

The European patent with the publication number 0 601 429 A2 contains a stone that is used to drain sealed surfaces becomes.

However, this stone lies directly with its water inlet openings the substructure of the seal. This will:

• 1. No permanent function guaranteed because the openings with the Block time with dirt that can flow freely and cannot be cleaned because there is no free space below the stone is there for;
• 2. does not prevent the seal from being washed away;
• 3. no reservoir is provided to accommodate large amounts of precipitation;
• 4. no target area is provided for the ventilation of the floor;
• 5. no retrofittable element for the existing ones Surface seals created.
