Description

System for efficient collection and drainage of groundwater
The subject of the invention is a system for efficient collection and drainage of groundwater which collects groundwater continuously and thus protects the building from the groundwater with the help of water drain units that can be placed next to foundations of buildings easily and even subsequently.
Protection of building from groundwater is a reoccurring problem for the construction industry. At certain places the problem cannot be resolved entirely by just providing various waterproofing to the parts of the building in the ground, its foundation and cellar walls. Where the terrain is sloping, the flow of groundwater could be consistent and in the given case rather strong, and the waterproofing cannot ensure sufficient solution. One of the most frequently used solution utilizes so called drain pipes laid in the ground next to the foundation of houses at various levels, by which drain pipes the groundwater can be collected and drained. This solution, however, requires large space and extensive work, because the drain pipes are usually placed in gravel bedding, which needs strenuous manual work.
According to the state of art the patent US 9 045 874 makes known a drain assembly for being placed at outdoor environment, which includes a first panel and a second panel spaced-apart from the first panel, a plurality of supports extending between the first panel and the second panel. And furthermore, a water collecting element is located at the bottom of the two panels, and their top is provided with a lid.
The patent publication US 2007/0294966 makes known a water drainage system to be used in waterproofing system of cellars. The pipeline has one or two lateral elements with openings to receive water beneath ground level. The pipeline may include an intermediate element also, which provides further strengthening of the structure. 0
The PCT patent description publication WO 98/11300 makes known drainage channel, which can be used when establishing a network to guide the drained water to the rainwater collector.
The British patent GB 2 087 457 makes know inner liner pipe for sewers.
The above solutions ensure collection and draining of groundwater with various methods. Experiences indicate that the quantity of groundwater flowing into the water collecting unit is low through the holes prepared on the side walls of the water collecting units placed in the ground with vertical walls. In this case the groundwater flows down on the side wall of the water collecting unit, and as the water cannot get into the collecting unit, it is only guided to a greater depth, and it is not collected or drained. Accordingly, the solutions described above cannot ensure a proper collection and drainage of water being in the ground.
While developing the solution according to the invention we had the aim of creating a water drainage system, by which it is possible to collect and drain the groundwater accumulating at the underground parts of the buildings in a more efficient manner, so that the water flowing down the side wall of the water collecting unit placed in the ground could be introduced inside the water collecting unit, and furthermore, we had the aim to provide a solution, by which the given groundwater drainage system could be deployed in a simple manner, and that it could be cleaned on a regular basis.
During the realization of the solution according to the invention we recognised that, if an arched surface with a given radius R, preferable shaped as a half circle is formed at the cross section of lower longitudinal water collecting element of the water collecting unit, and one of the upper edges of the water collecting element has a strait connecting part having a given length H, while the other edge of the water collecting unit is provided with an inwardly offset flange having water inlet holes, and this protruding flange has another straight upper connecting part having a given length H, and the width width S of the lower connecting element of the unit, then the set out aim can be achieved.
The invention is a system for efficient collection and drainage of groundwater, the units of which system consist of internal side walls connected to each other with braces, and perforated side walls, which units can be fitted to one another in longitudinal direction, and in the given case are placed on the top of another, and have closed or perforated lid fitted in a shape closing manner on the top of the internal side wall and the external side wall, and an arched water collecting element is located at the bottom of the internal side wall and the external side wall, and in the given case corner units are connected to the water drainage unit created in this manner. It is characterised by that, the longitudinally aligned lower collecting element of the water drainage unit is formed with an arched surface having preferably a semicircular shape with R radius, and one upper edge of the water collecting element has a straight connecting part having a given H length, while the other edge of the water collecting element has an inwardly offset flange in which water inlet holes are created, and has another straight upper connecting part having a given H height extending upwards on this inwardly offset flange, and the 2R width of the internal part of the arched water collecting element is larger than the external S width of the connecting part of the water drainage unit.
In a preferred embodiment of the solution according to the invention a flange, having water inlet holes, is mounted at both edges of the arched surface of the water collecting element.
In another preferred embodiment of the system according to the invention the holes in the inwardly setoff flange are circular or rectangular, and preferably are formed at one end of the water collecting element with arched fixing flange and an internal arched flange.
In a further preferred embodiment of the solution of the system according to the invention the side walls of the water drainage unit are coupled with braces, and a U shaped flange is formed at the lower part of the internal side wall and the external side wall of the water drainage unit, which U shaped flange is coupled to the straight connecting parts located on the longitudinally oriented water collecting unit of the water drainage unit, and fixing flanges are formed at one edge on each of the internal side wall and the external side wall of the water drainage unit, and fixing flanges are formed at one lateral edge on each of the internal side wall and the external side wall.
In a further preferred embodiment of the solution according to the invention a closed lid, or a perforated lid of a sloping lid having flange and groove is connected in a shape closing manner to the internal side wall and the external side wall at the top of the water drainage unit.

Fig. 13 shows a further possible configuration of the installation of water drainage unit. Fig. 1 shows a possible embodiment of the water drainage unit 1 of the system according to the invention with perspective view. The water drainage unit 1 can be seen in the figure in a condition before assembling. As can be seen in the figure, there is an internal side wall 6 and an external side wall 7 provided with holes 17, having fixing flanges 12 at their ends. The internal side wall 6 and an external side wall 7 are provided with U shaped flange 13 at their bottom, which U shaped flange 13 contains a groove 14. In addition to that, the internal side wall 6 and an external side wall 7 are connected with braces 8. At the same time, the length of the braces 8 determine the distance between the internal side wall 6 and the external side wall 7.
It can be seen well in the figure, that a closed lid 4 is placed on the top part of the internal side wall 6 and the external side wall 7. The closed lid 4 has a flange 10 and the groove 11 next to the flange 10. In this way, the top parts of the internal side wall 6 and the external side wall 7 are fixed into the grooves 11 of closed lid 4 in a shape closing manner.
The figure also shows, that an arched water collecting element 9, shaped as a half circle, is connected to the lower parts of the internal side wall 6 and the external side wall 7, so that its two edges are fixed into the grooves 14 of the internal side wall 6 and the external side wall 7.
The water collecting element 9 is created with a horizontal inwardly offset flange 60, and water inlet holes 67 are prepared in the flange 60. There is an arched fixing flange 15 formed on the external surface at one end of the water collecting element 9, and there is an internal arched flange 16 on its internal surface. The function of fixing flanges 12, the arched fixing flanges 15 and the internal arched flange 16 is to make sure that the ends of internal side wall 6 and the external side wall 7 are accurately aligned side by side when the water collecting units 1 are fitted together in longitudinal direction one by one. In addition to that, the fixing elements 12 that protrude at the internal side wall 6 and the external side wall 7 align the water drain units 1 relative to one another, and they also ensure a cover at the fitting parts. At the same time, the lower water collecting elements 9 of the water drainage units 1 are fitted together in a way, that the end of one water collecting unit 9 is slid between the arched fixing flange 15 of the other water collecting unit 9 and the internal arched flange 16. Here the necessary cover is ensured by the arched fixing flange 15.
Fig. 2 shows a possible embodiment of the water drainage unit 1 in fitted condition. It can be seen in the figure, that in this case two water drainage units 1 having internal side walls 6 and the external side walls 7 are assembled in a way, that the upper edges of the lower water drainage unit 1 are fitted into the groove 14 of the upper water drainage unit 1 in a shape closing manner. The sloping lid 58 is placed on the top of the water drainage unit 1. A water collecting element 9 provided with flange 60 is fixed to the bottom of the lower water drainage unit 1 in a way, that the upper edges of the water collecting element 9 are fitted into the groove 14 of the lower water drainage unit in a shape closing manner.
The largest width S of the water drainage unit 1 is shown in the figure at the external plane of the U shaped flange 13. The internal width 2R of the arched surface 61 of the water colleting element 9 is also shown. Because of the width of flange 60, the internal width 2R of the arched surface 61 of water collecting element 9 shall be larger than the maximum width S of the water drainage unit 1. This arrangement ensures that the water flowing down the external side wall 7 will get into the water collecting element 9 for sure. In the given case, it is possible to place a flange 60 at both edges of the water collecting element 9, as a result of which the water flowing down can be collected at both sides of the water drainage unit 1 , and it can be routed inside the water collecting element 9.

In case of another possible preferred embodiment, the water collecting element 9 may be established in a way, that the flange 60 having water inlet holes 67 is formed at both edges of the arched surface 61 of the water collecting element 9. In this case the radius R of the arched surface 61 is to be increased, so that the connecting parts 62, 67 could fit into the grooves 14 formed by the U shaped flanges 13 of the internal side wall 6 and the external side wall 7 in a shape closing manner.

The figure shows the closing plate 20 of the corner unit 2 created with coupler pins 28, 29, together with an opening 21 formed at its lower part. In this case the closing plate 20 is formed with a flat surface 63. It can be seen, that external positioner surfaces 23, 26 are fixed to the external surfaces of the coupler pins 28, 29, while internal positioner surfaces 22, 25 are fixed to their internal surfaces.
It can also be seen, that the external positioner surfaces 23, 26 and the internal positioner surfaces 22, 25 fixed to the coupler pins 28, 29 actually form the arched grooves 24, 27.
As can be seen the in the figure, there is a profile shaped part 43 on the lower part of one shank of the internal positioner surface 22 in front of the arched section, and there is a profile shaped part 45 on the lower part of the same shank of the external positioner surface 23 in front of the arched section, and the profile shaped parts43, 45 form the nest 44.

In this case the water drainage units 1 coming from two directions are coupled to the corner unit 2 in a way that the internal side wall 6 and external side wall 7 of the water drainage unit 1 are slid into the upper section of the arched groove 24 in a shape closing manner. At the same time, its water collecting element 9 is slid into the lower arched part of the arched groove 24, and in this case the U shaped flanges 13 of the internal side wall 6 and external side wall 7 are slid into the nests 44, 47 also in a shape closing manner. The same process is repeated at the other side of the corner unit 2 where its groove 27 is located. The corner unit 2 shown in Fig.6 in the given case is suitable for establishing a corner with inclination angle a = 90°, but it can be produced also with any inclination angle in the range 45° < a < 135°. Fig. 7 shows the extension unit 3 of the comer unit 2 introduced in Fig. 6 in perspective view. If the collection and drainage of groundwater needs to be done in a greater depth, for the purpose of which two or more water drainage units 1 are assembled on top of one another, then the corner unit 2 is to be made higher also.
