Description

The The invention relates to a method for filling a modular system of fluid receiving containers and emptying the same, wherein the containers are arranged in a body of water and each container has an inlet and a drain for having the fluid. The invention further relates to a new use one or more containers.

The Fluid receptacles may be both partial as well as completely arranged in a body of water be, z. B. also floating.

in to be accommodated by the modular system of containers Fluid can be mixed water. In a sewer system, which absorbs both sewage and rainwater, it can in particular in heavy rain to an increased attack of mixed water come. Since the absorption capacity of the sewer system, which are connected to the sewerage network, is limited Mixed water receptacle provided in the receiving capacity exceeding Mixed amount of water is passed. The mixed water is in the receptacles stored until the sewer system at a later time Time again have enough recording capacity, though For example, by decreasing rain, the mixed waterfall decreases.

In order to reduce the space requirement of such fluid receptacle is in the DE 103 38 419 A1 proposed to arrange them floating in a body of water or immersed in it. It is expedient to use the fluid receptacle in the vicinity of an introduction of the sewer network in the shore area of the water. Thus, a sewer system, which is not yet provided with mixed water storage tanks for intermediate storage of the mixed water, can be retrofitted in a simple and cost-saving manner with such containers.

Yet is the installation of fluid receptacles in one Waters not unpretentious. Especially in the empty Condition when no fluid is stored in the containers and the containers are provided for receiving fluid are acting on them, a strong buoyancy. Therefore, must the container through a suitable foundation, through a large net weight or by attaching a surcharge be kept at the water bottom, said measures must be sufficient in total to the strong buoyancy to withstand sufficient safety. The previously for this proposed solutions prove in their technical design and the costs still considered too costly to be economical to convince.

Of the present invention is based on the object in a body of water to be mounted fluid receptacle in optimally easier Provide a way and keep it at the bottom of the water.

The The object is achieved according to the invention that in a method for filling a module system of fluid receiving containers and emptying the same the initially mentioned type, the container further with a Inlet and outlet for the ambient water of the water body be provided, wherein at least a part of the container is filled with ambient water of the river, if no need to take up the fluid through the module system and no partially filling the same by the fluid and the ambient water from at least part of the filled with him Container is pumped out into the water if needed for receiving the fluid through the modular system.

by virtue of the method of the invention, the buoyancy the fluid receptacle are considerably reduced, by always having a number of containers with the fluid and / or the ambient water of the water are filled. The number of filled with fluid and / or ambient water Container may vary depending on the weight of the Container should be so determined that the remaining buoyancy through the possibly empty containers, which are used to hold additional fluids are provided by the total weight of the Container is compensated. The containers can then through a relatively unobtrusive foundation safely kept on the water bottom, since the foundation the buoyancy forces of the container no longer has to absorb.

In the trap that due to the possibly emptied container and / or saving unnecessary weight a resulting Buoyancy remains, but according to the invention reduced This can be done by founding the container be compensated on the water bottom, the foundation also can be accomplished without much effort. Depending on the sediment layers found of the river bottom, a simple low or flat foundations.

Conveniently, can be provided, always only with each container Fluid or to fill with ambient water, but not to mix both in a container. In special circumstances however, it may be advantageous to include both in the container To absorb liquids.

The containers forming the modular system may be interconnected by overflows such that when a container is filled with fluid or ambient water, the fluid or ambient water flows into the next adjacent.

In a preferred embodiment of the invention, the number of Containers filled with ambient water from which the ambient water in order to provide a volume for the acquisition of Fluid is pumped, depending on the needs be controlled at the intake of the fluid through the module system. For mixed water storage tanks, the regulation can connect to the urban pumping station. If from there the message comes that a relief event is expected is, ie the inflow of mixed water into the water in a heavy rainfall, depending on the Size of the discharge event with emptying a corresponding number of containers, the ambient water included, to be started. Thus, on long term empty containers be waived.

in Such a regulation can be provided that all containers be kept filled with fluid or ambient water, if there is no need to take up the fluid or other fluids through the module system exists.

on the other hand However, it may be in constant preparation for a relief event be provided that a certain number of containers always kept empty, if not all containers of the Module system are filled with the fluid.

In a preferred embodiment of the invention, the container the dimensions of containers that are easily transported can. In particular, come as a container in the trade Available containers in question, in a simple way can be equipped as a fluid receptacle. The containers are complete with accessories in the Factory pre-assembled. They are usually designed that they can be easily transported to the place of use. There is then only the connection to the sewer and the Foundation on the water bottom to accomplish.

One Container, so a module of the modular system, can consist of several Containers exist among themselves for the purpose of fluid exchange Fluid filling or ambient water exchange with ambient water filling are connected.

Especially the containers can communicate according to the principle Be connected to tubes.

In a preferred arrangement, the containers are on one side, z. B. longitudinally disposed adjacent to each other, wherein the partitions are removed. Thus, continuous spaces without intermediate partitions with large Capacity provided for the fluid.

In particular, can be used as container ISO containers.

The The above object is further inventively the use of one or more containers as fluid receptacle dissolved in a body of water, the container rigid walls and an inlet and a drain for the fluid and an inlet and outlet for the ambient water of the water body.

in Such a container may, as stated above, to trade an ISO container.

As already stated above, offers the use of a or more containers with rigid walls and one inlet and drain for the fluid and the ambient water an optimally easy way to him as a fluid receptacle to provide in a body of water. The container can be in Trade easily procures as a fluid receptacle for a body of water. The entire pre-assembly can be done at the place of manufacture. Because such containers are designed so that they are the easiest way with it transported vehicles and transported with it provided cranes can be moved they can be deployed easily on site and in the shore area of the Sink water into this.

The Containers can easily handle inlets and outlets for the fluid and the ambient water of the water body, with pumps provided and with others for fluid caching appropriate technologies be equipped. Containers offer under all for the fluid intermediate storage previously proposed containers the easiest solution. The advantages mentioned meet in particular to ISO container too.

The containers, which are equipped or retrofitted as fluid receptacles, after they have been transported to the place of use, are assembled into a respective module and connected to the sewage system by one or more pipes. Several such modules are arranged to the module system used as mixing water buffer. As described above, one or more modules are kept empty or, in the case of volume delivery control, pumped empty as needed. When mixed water accumulates, it first fills this module. At the same time, further modules, which have hitherto been filled with the ambient water from the water body, are pumped empty in a fixed number or in regulation as required. Thus, the entire system successively mixed with be filled while ambient water is pumped out of it into the water. If the module system is completely filled with mixed water, the system waits until the sewerage system in question is ready to start again. Thereafter, the process is reversed by the mixed water is pumped successively, while the ambient water of the water, preferably by its own pressure, flows into the modules. In this case, a part of the container remains empty. Once all of the mixed water has been pumped out of the module system, the entire system may be filled with ambient water, if timely information about a relief event and, possibly, the size of the discharge event is expected, or if a fixed number of containers are kept empty to provide a given volume , In the former case, emptying is started only when an unloading event is reported. In the latter case, irrespective of the message of a discharge event, one or a certain number of modules that have been pumped empty are available for receiving mixed water.

In Dependence on the total weight of the modules and the maximum number In some cases empty modules may be the attachment by flat or deep foundation at the bottom of the water being held.

Around in addition to the buoyancy due to the weight of the modular system counteract the containers with a ballast be complained about.

The Containers may be pumping devices for pumping out the fluid and the ambient water through the respective sequence.

Farther The containers can be a device for rinsing of deposits of the fluid. In particular, this device can have one or more vortex jets. With such vortex jets solids can be kept suspended become and / or forming deposits for the cleaning of the soil the container will be solved.

to Prevention of deposits in the containers can these or from several composite modules also a closable opening have on a side wall near the ground, by the ambient water flows into the container with appropriate pressure and thus rinses off deposits. The influx of the ambient water, for example, by opening a Slider done.

Around It is easier to rinse off deposits preferably the bottom of the container is inclined.

Farther the containers are preferably provided with smooth inner sides. The insides can also be a dirt-repellent layer exhibit.

to Maintenance of the containers can make these on their top Have entry opening.

The Containers can continue to use technologies for cleaning of the fluid, for example by ozone, UV light, sieving, precipitation and / or flocculation.

advantageously, the containers have a level gauge, which the respective filling and thus the remaining volume for receiving the fluid or ambient water and the complete Filling registered and displayed.

The Surfaces of the containers can be used be used to foundations in the shores of the water body for example, platforms, superstructures, green spaces or to create facilities for the treatment of wastewater.

embodiments The present invention will become more apparent from the following description made with reference to the accompanying drawings described. In the drawing show

1 a simple module in the shape of a container,

2 another version of the in 1 shown containers,

3 the module after 2 with foundation and surcharge,

4 a combination of several containers after the 1 and 2 to a module with a larger capacity and

5 a five-module system with three modules filled with ambient water, one module empty and the fifth module filled with mixed water.

In 1 is a fluid receptacle 1 as a simple module of a modular system of such containers 1 shown, wherein the fluid receptacle 1 manufactured in the dimensions of a container, so that the transport can easily take place. The container 1 can be pre-assembled completely at the place of manufacture together with the other containers forming the modular system. After its transport to the place of use together with the other containers, only the connection to the sewage system and the foundation are made there.

The container is connected to the (not shown in the drawing) drains through a pipeline. In 1 shown is the inlet 2 and expiration 3 for the fluid, that is, the mixed water obtained in the sewerage in each case, in the form of a pipe socket. The sequence 3 leads to the vicinity of the tank bottom 4 , Furthermore, in 1 a pumping device 5 shown with the mixed water from the container 1 can be pumped back into the sewage system.

The container 1 also has a feed 6 and drain for the ambient water of the surrounding it (not shown in the drawing) waters 5 on. The process is with the process 3 identical for the mixed water. Through him, both the mixed water and the ambient water through the pumping device 5 pumped out. While the mixed water through the pipe 7 is pumped back into the sewer, z. B. by a two-way valve, the ambient water through the pipe 8th pumped back into the water.

The container 1 also points to its bottom 4 , a vortex jet 9 for preventing sedimentation. In addition, a level gauge, control devices for the pumping device 5 and control devices for the entry and discharge of mixed water and ambient water depending on the size of the reported discharge event or a reported recovery capacity of the sewer systems.

The container 1 is equipped with smooth side walls to minimize deposits. The tank bottom 4 points you to the process 3 for the mixed water inclined course, so that deposits can be easily rinsed off.

The container 1 may eventually be equipped with technologies for the purification of the mixed water, for example by ozone, UV light, screening, precipitation and / or flocculation.

The insides of the container 1 are with a dirt repellent layer 10 provided for the reduction of dirt deposits. At the top of the container 1 may be a (not shown in the drawing) manhole for maintenance of the container 1 be provided.

2 shows a variant of the container 1 , where instead of a vortex jet of the inlet 6 at the expiration 3 opposite end face to prevent and rinse off deposits ambient water with a corresponding pressure in the container 1 flows. The ambient water can through the inlet 6 by opening a slider 11 in the container 1 flow.

3 shows schematically a possible foundation of the container 1 in the bottom of the water. The foundation is as deep foundation with the help of piles 12 executed.

In addition, the container 1 to keep his buoyancy in the waters at the bottom of the water is on top of the container 1 a surcharge 13 intended.

The buoyancy of the container 1 in the water, however, is significantly reduced by a successively described below by way of example successive filling and emptying of the module system from such containers with fluid, ie mixed water in the example considered here use, and ambient water.

How out 4 shows are several containers 1 , which are the size of a container, combined by removing the long dividing walls into rooms with a larger capacity. This example of four containers 1 existing module then has only one inlet 2 for the mixed water and a feed 6 for the ambient water. Furthermore, there is a procedure 3 vorgese for the mixed water and the ambient water hen. To pump out the mixed water or ambient water, the pump device is used 5 ,

The from several (here four) containers 1 Containerized modules are assembled at the jobsite and lowered into the water in the shore area.

5 shows an arrangement of five modules in the shore area 14 of the water 15 , The modules are attached to each other along the longitudinal side and fixed by piling on the bottom of the water. In order to keep the buoyancy of the module system as low as possible and thus reduce the cost of the foundation in the water bottom, it is provided that the module system is constantly filled up to a maximum of one module with ambient water of the water and / or mixed water from the sewer system. This happens as follows.

As long as there is no need for receiving mixed water from the sewerage system and there is no partial filling of the module system with mixed water, at least part of the modules is filled with ambient water of the water body. In the considered embodiment, in this situation, the in 5 Left module shown empty, while the remaining four modules are filled with ambient water. When mixed water enters the module system through the sewer, it first fills the empty module. At the same time, the module adjacent to the right, which has hitherto been filled with ambient water, is pumped empty. This situation is in 5 shown.

If the first module is filled and more mixed water is flowing through the sewer system, the second module is filled. Meanwhile, the surrounding water is pumped out of the third module located to the right. Thus, the entire module system can be successively filled with mixed water until at most all modules of the system are filled with mixed water and thus the absorption capacity of the module system is reached. The mixed water then remains in the module system until it can be resumed through the sewerage system. Then, the mixed water from the modules is successively pumped back into the sewerage system, each by an empty pumped container 1 is filled with ambient water of the water through the corresponding inlet. This can be done by opening the in 2 shown slider 9 respectively.

If the sewerage system is able to take up the total mixing water volume of the modular system, either the last empty pumped module, which is in 5 module shown on the far left, filled with ambient water, if sufficient time remains to be given to discharge the module from the ambient water if the discharge event is expected in good time, or the module is kept empty in the standby mode of a mixed water inflow.

to successive filling of the modules with mixed water or ambient water can be the next adjacent modules be connected with an overflow, so if a module is filled with mixed or ambient water and more Space needed to hold mixed or ambient water is, the water flows into the next adjacent module.
