Description

The invention relates to a drain well for wastewater, in particular to a groove drain well according to the preamble of claim 1.

Drain wells (however, not for gutters) having a revision that comprise openings provided with a locking element are known in a wide variety. As an example, reference can be made to the publications DE 36146, DE 102006053751 A1, DE 4411492 C2, DE 2434895 A1, DE 1854390 U, DE 1826194 U, DE 1825087 U, DE 1854795 U or DE 1816291 U. In the known drain wells, there is a problem that on the one hand, after some time, revisions cannot be opened, that is, the locking elements can no longer be removed, on the other hand, the complete cleaning of the drain wells is very difficult.

The basis of the invention is the task of improving the drain well of the previously mentioned type in order to ensure its applicability, especially in terms of complete cleaning in a simple way.

This problem is solved in the claimed drain well for wastewater, especially the trench drain well.

The drainage well of the invention proposed for wastewater, especially a chute drainage well, has a receiving box that is designed to receive and hold a reservoir with a siphon drainage valve and has at least one immersion wall that projects into the reservoir and forms at least one bottom of the reservoir at least one hole through which wastewater flows and has a barrier through which wastewater flows and which forms a maintained level of wastewater in the tank. The wastewater drainage well of the invention also has a drainage box that accommodates overflowing wastewater and directs it into the drain pipe fitting, and a revision that includes an opening to be closed by a locking element through which the drain pipe fitting is accessible without crossing the receiving box. The problem is solved by the fact that the hole is located below the barrier, that is, below the supported level, and the revision contains a fitting that stands at the bottom of the tank and is open upwards, and also open from the side, i.e. side, to the drain box and fitting. This ensures simplicity of design, as well as a high level of production and operational manufacturability. In addition, air oxygen is not allowed to the hole and the locking element. This provides increased durability. In addition, thanks to this design, it is easier to remove water from the tank with a siphon drainage shutter, that is, to remove particles accumulated there.

Preferably, the audit is located inside the receiving box. This provides easy access.

Preferably, the drain box has an inclined bottom towards the nozzle. This ensures that the incoming dirt particles are fed to the fitting of the drain pipe with a relatively high flow rate, that is, they cannot catch.

The immersion wall passes through several sides, primarily two sides, of the receiving box. This ensures that even unexpectedly large amounts of water can be discharged without interruption.

Preferably, the barrier delimits the reservoir from several, especially two, sides. This also leads to improved drainage of rather large flows of water.

Preferably, the emptying device further comprises a U-shaped curved hose. It can be used, and then it sucks out the liquid located in the tank with the siphon drainage gate, and even quite large mud particles can be removed.

Preferably, the locking element is designed so that it is installed in the hole with its overlap and can be removed from there without tools. Since the hole lies below a supported level, with small leaks that are large enough to leak fetid gases, it is quite possible to put up. After all, these leaks are sufficiently sealed by the liquid level, and the flow of water and the emptying of the tank with a sewer siphon lock still does not occur.

Preferably, the receiving box on its upper side is made with a transition to the flange section so that a drain gutter is attachable. Thus, with simplicity of design, ease of installation is ensured.

Next, a preferred embodiment of the invention is explained in more detail using the drawings. It is shown:

in FIG. 1 is a schematic longitudinal section,

in FIG. 2 is a side view of the device according to FIG. 1,

in FIG. 3 - section along the line III-III in figure 1,

in FIG. 4 - an embodiment of the device according to figure 1 with inserted U-shaped curved hose,

in FIG. 5 - the device according to figure 4,

in FIG. 6 is a section along the line VI-VI in figure 4,

in FIG. 7 is a perspective view of an embodiment of a drain well shown here; and

in FIG. 8-14 are various cross-sectional images of the device according to FIG. 7, whereby a sectional plane is indicated.

In the following description, the same reference signs are used for the same and having the same function parts.

As shown in FIGS. 1-3, a receiving box 10 is provided, which on both sides has immersion walls 11 and 12 that end above the bottom of the tank 17 and thereby form slit-like openings 13, 14.

Further outward, with an offset towards the outer walls 23, 24 of the receiving box 10, barriers 15, 16 protrude from the bottom of the tank 17, determining the maximum level of liquid that may be present in the receiving box 10.

When the liquid level rises, the liquid overflows through the barriers 15, 16 and then flows into the drain box 20. This drain box 20 is formed by the outer walls 23, 24, the bottoms 21, 22, the front wall 25 and the rear wall 26.

The bottoms 21, 22 of the drain box 20 are inclined towards the nozzle 30 of the drain pipe, so that water flowing through the barriers 15, 16 flows at a high flow rate towards the nozzle 30 of the drain pipe along the drain box 20.

In the receiving box 10 or with a protrusion from the bottom of the tank 17, a revision 40 is provided, which includes a fitting 43 having an opening 42 on its upper side. An inspection hole 45 is provided on one side 44 of the fitting 43, so that the inside of the fitting 30 is hole 42 and inspection hole 45 are substantially freely accessible. To close the opening 42, a locking element 41 is provided, preferably made in the form of a plug, which can be inserted into the opening 42 by hand with a tapered side surface, that is, without using a tool. Preferably, this locking element 41 may experience elastic deformation.

When the drain well shown here needs to be cleaned, an emptying device 35 may be used, comprising a substantially U-shaped hose, which when inserted into the opening 42 with one free end ends near the bottom of the tank 17 and its second end extends towards the nozzle 30 drain pipe. With the quick introduction of the emptying device 35 into the opening 42, the liquid level is high enough so that the liquid passes inside the U-shaped tube and then there is a well-known absorption. If this does not happen, then by adding liquid, the liquid level can be increased so that filling of the U-shaped tube is ensured. Then the emptying process takes place without difficulty.

Finally, the receiving box 10 on its upper side has outwardly extending flanges 18, 19, as well as a gutter-shaped inlet portion, so that a correspondingly shaped gutter can be directly connected.

The details described above are once again shown, first of all, with the help of FIGS. 7-14, and here the volume of disclosure of these figures, including the dimensions given there, is strongly indicated.
