Abstract

The module (1) has shell parts that include two quarter shells (2,2`), and one half shell, where the quarter shells adjoin one another in an area of a crown line (5) of a groove wall in such a manner that an inlet groove is formed along the crown line. The inlet groove is bounded by two inlet surfaces, which extend away from edges of quarter shells approximately parallel to the outside of the groove.

Description

The The present invention relates to a retention channel module for construction a retention channel for an underground storage of surface water, wherein the retention channel module composed of shell parts.

One Such retention channel module is already known from DE 20 2005 004 634 U1 previously known. There is in particular described that a Retention channel of at least one gutter base and a gutter shell consists, to enlarge the capacity an intermediate layer of elevations is possible. Such a retention channel has openings at the top of the channel top up, over which can be connected to the gutter inlet, which preferably run apart funnel-shaped in the area of the surface. The resulting inlet is overlapped by a rail, which forms a cover grille with the release of inlet slots. Through this design is achieved that both the installation depth of the gutter due to retractable inlet nozzle, as well as the gutter capacity due the elevation pieces variable is held.

Generally Such retention channel modules are preferred for surface drainage from airports or similar large-scale plants used. The retention channel is essentially a kind of buffer, in the accumulating surface water retained and gradually to the soil or the sewer system is delivered. about slot-like inlet openings gets the surface water into the retention channel and is over derived a predetermined sequence. Through this cache is in heavy rains an overload the sewers avoided, which otherwise cause flooding of important traffic areas to lead can.

Known Retention channels are cast in one piece and therefore not variable. The retention channel described in DE 20 2005 004 634 U1 overcomes this disadvantage in that it is composed of several shell parts.

however dwells this disadvantage the disadvantage that it with the variable Design goes along with that the inlet pipe a bottleneck embody, in which dirt, leaves or the like can set. These be over washed in the funnels and can to settle in the union, what functionality of a gutter can significantly restrict.

Of the The invention is therefore based on the object, a retention channel to create, which with few differing from each other Elements can be produced and on bottlenecks at the inlet nozzle waived.

Is solved this task by means of a retention channel according to the features of the main claim. Further advantageous embodiments can be taken from the subclaims become.

According to the invention the retention channel module of several shell parts, of which at least two shell parts are quarter shells and which one together forming tubular body. The intended purpose of the Although the top of the trough arranged shell parts encounter though to each other, so that the gutter module has the associated stability. However, the push is not continuous or even impermeable, but rather only executed selectively, so that between the shell parts Upper side, an inlet slot is released. Through this inlet slot can be on the surface accumulate accumulating water in the retention channel, wherein a Entry of coarser Material possible is, due to the shape of the inlet slot a blockage of the inlet nozzle is avoided.

With Supplement advantage the said quarter shells with only one additional Half shell to a complete Tube.

The Shell parts are preferably made of a particularly robust and water-resistant material as produced by PEHD, but also other materials such as galvanized Steel or stainless steel are suitable.

In meaningful development of the inlet slot is limited by two inlet surfaces, which run largely parallel to each other and an inlet channel into the gutter. This eliminates the need for additional use Inlet connection.

retention grooves become common under traffic areas used, so that usually a high load on the gutters acts. Therefore, the inlet surfaces of the Shell parts, preferably with the aid of spacer screws, with each other connected so that a displacement or bending of the gutter parts, especially the inlet, is avoided.

In order to present on the surface no obstacle and no risk of injury, the inlet is advantageously associated with an essay, in particular made of plastic or metal, such as sheet metal. As a result, the stability of the channel, in particular in the region of the inlet is increased. Such a reinforced channel can be approximately in the area of traffic areas which are exposed to an increased load, such as heavy goods traffic. In addition, an optical termination of the groove is created.

With Advantage is this slotted sheet or cover grille with an anchor provided by means of which a fixation of the slot plate or the grating is made possible either with the gutter or with the soil.

The Shell parts are mutually beneficial with a connection mechanism connected, such as with a tongue and groove connection. Otherwise, can the shell parts are bolted together or over a Flange to be connected. Likewise, compounds are among several Gutter modules possible.

to Improving the dimensional accuracy of the gutter, it is extremely advantageous if, at least a shell part stiffening ribs are assigned, which the Support outer walls. By the shell part construction may optionally also on individual Parts used where ribbing can be omitted.

With It is particularly advantageous for the shell parts to be able to attach elevation pieces, with the aid of which an enlargement of the height is achieved Channel volume and thus an increase in capacity created can be.

The The invention described above will be described below with reference to a explained in detail in the drawing embodiment.

It demonstrate

1 a retention channel module consisting of a half-shell and two quarter-shells in a perspective view, as well

2 the retention channel module off 1 with a slotted sheet, also in a perspective view.

1 shows a retention channel module 1 a retention channel, consisting of a half-shell 3 covering the bottom of said retention trough module 1 forms as well as two quarter shells 2 . 2 ' which the half shell 3 to complement an almost completely tubular body. Between the two quarter shells 2 . 2 ' is an inlet slot 5 released, about which in the installed state of the retention channel module 1 Surface water can flow into the retention channel. The inlet slot 5 is from two inlet surfaces 6 . 6 ' fringed, so that a greater installation depth of the entire arrangement can be achieved. The width of the inlet surfaces 6 . 6 ' specifies the achievable installation depth. The inlet surfaces 6 . 6 ' are also using spacer screws 4 interconnected, whereby a pressure and tension-resistant connection of the two surfaces is ensured. As a result, a shift and / or deformation of the inlet surfaces 6 . 6 ' formed inlet avoided.

2 shows the retention channel module 1 out 1 , this one as essay a slotted sheet 7 is assigned so that it is the inlet, at the inlet surfaces 6 . 6 ' fitting, completely overlapping. It thus contributes to increasing the stability of the arrangement by the two inlet surfaces 6 . 6 ' additionally supported against the forces acting. The slotted sheet 7 is by means of anchors 8th connectable to the soil, so that also a shift of the slot plate 7 not done from the specified position above the inlet.

The retention channel module 1 are also for stiffening stiffening ribs 10 associated, whereby a greater load capacity of the outer surfaces is achieved. At the front end of the retention channel this is an end wall 11 connected, which a connecting piece 12 having. About this connection piece 12 the water stored in the retention channel is slowly released to the sewage system.

above Thus, a retention channel module is described, which in the capacity and the installation depth is variable and at the same time a large inlet cross-section to prevent blockages.
