Abstract

The invention relates to a device for draining rainwater and the like. with a seepage or manhole (1) covered at the top by a channel grate (2) and preferably a mud trap (3). While it is the object of the invention to drain only purified water or dosed to drain into a sewer network, the object is to provide a device for draining rainwater and the like. to create, in which the rainwater dosed through a small passage opening in the bottom is discharged into a connected channel and / or seeped through at least one riser through drainage pipes. According to the invention, the device according to the object is achieved in that the shaft (1) to the seepage layer (s) of the substrate towards a watertight intermediate bottom (4) with passage opening (5). In the shaft (1), at least one riser pipe (7) which can be connected to a drainage pipe (11) entering from the shaft wall (10) is arranged at a distance above the ground (13). As a result, with good seepage and simple design, cleaning of the water to be drained and also easy cleaning of the discharge device is achieved. Figure 3

Description

Lightweight materials are prevented from flowing with it. The dense soil allows a simple, rapid cleaning of the shaft and after a decrease in the riser pipes and the drainage pipes can be cleaned well, for example by a high-pressure purge. The devices according to the invention can be installed in virtually any kind of seepage or manhole and it is also possible to retrofit existing tunnels with these devices.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawings, Figs. 1 to 4 show four different embodiments of the device according to the invention in each case in vertical section. The device for draining rainwater consists of a seepage shaft 1, which is covered at the top by a channel grille 2 and a mud trap 3 and extends down to a seepage layer S. According to FIG. 1, the seepage shaft 1 has an intermediate bottom 4, which closes off watertightly to the seepage layer S and has a passage opening 5, a downpipe 6 being tightly inserted into the passage opening S, which merges into a riser pipe 7 ending at a distance above the bottom 4. This riser 7 brings now together with the downpipe 6 a simple effective cleaning of the water to be infiltrated with it, since the penetrating into the seepage shaft 1 water to the height of the pipe bend 8 between riser and downpipe 7.6 must rise before it through the Rising pipe 7 and the downpipe 6 can get into the seepage layer S. This percolating water is free of contaminating light and heavy materials, which collect on the one hand on the water surface, on the other hand settle on the intermediate bottom 4, so that only purified water is withdrawn through the riser 7. According to FIG. 2, the seepage shaft 1 a is provided with a closed bottom 9 and drainage pipes 11 extend from the shaft wall 10, to which in turn at a distance above the bottom 9 rising risers 7 connect. Again, it comes through the risers 7 to a purification of the water to be seeped from the light and heavy materials, the water seeping over correspondingly long, approximately horizontally laid drainage pipes. According to Figure 3, a seepage shaft 1 is provided with an intermediate bottom 4, wherein both a downpipe 6 and a drainage pipe 11 are each provided with a riser 7 for infiltration of rainwater entering. The dashed parts in Fig. 3 relate only to application examples for increasing the infiltration surface. The embodiment of Figure 4 shows a manhole 1 b with a sewer pipe connection 12 which is covered watertight by an intermediate bottom 13 with a passage opening 5, in which in turn sits in a riser 7 downpipe 6. In addition, there is an outgoing of the channel wall 10 drainage pipe 11, to which also a riser 7 leads. By covering the sewer pipe connection 12 with the intermediate bottom 13 and its riser and downpipe, the rainwater discharged into the duct is also cleaned, the dosed drainage of rainwater into the duct being effected by the relatively narrow cross section of the downpipe 6 or the throughflow opening 5.

The closed down seepage and manhole and connected to fall or drainage pipes and thus leading out of the channel riser ensure a rational way coarse and lightweight separation and thus the desired water purification before seeping, the shaft and the pipes easily accessible and easy to clean, resulting in a particularly effective, durable and above all, environmentally friendly Wasserableiteinrichtung.

For this 2 pages drawings Field of application of the invention The invention relates to a device for deriving rainwater u. Like., With an upwardly through a channel grate and preferably a mud trap covered seepage or manhole. Characteristic of the known technical solutions To rainwater u. Like. To deduce, it is customary to invest in the gravel surface of the ground extending drainage shafts, but these seepage shafts except possibly a sludge trap under the cover no water purification device so that all inflowing water, including soiled water, seeped what Not only with regard to the groundwater and the environmental impact is questionable, but also leads to a fairly rapid sludge and inefficiency of the seepage shaft. The shafts ending in the gravel underground are hardly to clean, their effect therefore decreases relatively quickly and because of the lack of cleaning ability of the water and the short duration of their use is limited and even prohibited in water conservation areas. The same applies to manholes, which are directly integrated into a sewer system and also supply the rainwater unpurified and without dosing to the sewer system. In heavy rainfall, thunderstorms u. Like., Therefore, there is a risk of overloading the channels with unpleasant water leaks from the manholes. In the documents mentioned below are devices for draining rainwater u. Like. Described, with which was trying to seep only purified water or dosed to drain into a sewer network. Thus, from DE-OS 3247944 known to initiate the water in a reservoir via a manifold and a filter device and dissipate from the reservoir via an overflow into a drainage system. This device requires a high construction cost and their only dependent on the filter device and their maintenance cleaning effect remains unsatisfactory in practice. Sink pits are known from GB-PS 8322 and US Pat. Nos. 4,298,470,848,279 and 7,028,111, the cesspools of which are equipped with special overflow devices for the liquid portion of the cesspit contents, but these cesspits are not suitable for the usual discharge of rainwater. Object of the invention The object of the invention is to provide a device for draining rainwater u. Like. To provide the seep in a structurally simple, effective way, only purified water or doses can flow into a sewer system. Explanation of the essence of the invention The invention is based on the object, a device for draining rainwater u. Like. To create, which delivers the resulting rainwater through a small compared to the shaft cross-section opening in the bottom in a connected channel and its overload in heavy downpours u. Like. Prevents and / or rainwater seep through at least one lintel through drainage pipes to clean dfts waters of light and heavy materials. According to the invention, the object is achieved in that the shaft to the 'seeping layer of the substrate or above a sewer pipe connection a waterproof floor, in particular intermediate floor aufv / eist, provided in the bottom of an opening and / or in the well at least one known per se, to e! ; ie the drainage pipe, which can be connected to the drainage pipe, is arranged at a distance above the ground. A particularly advantageous development of the invention is that in the passage opening of the bottom, a downpipe is tightly inserted, which merges into a distance above the bottom end of the riser. This ensures that due to the closed manholes, the heavy materials settle to the bottom and only gravity-free water can flow through the riser pipes through which the floating on the water surface
