Description

Pumping station

The invention relates to a pumping station containing a shaft as an outer wall and a base plate on which there is a sewage lifting plant.

Such pumping stations are known to be required in waste disposal facilities to remove z. B. sewage or the like to be able to dissipate. For this purpose, the pumping stations have their own wastewater lifting plant.

The assembly of the well-known pump stations, which have been tried and tested, has so far proven to be quite time-consuming in practice and thus also proven to be cost-intensive.

Usually an excavation pit is first dug, and then the walls are clad or otherwise secured. Next you usually have a concrete base or the like is made on the floor of the excavation pit that has been completed so far, and the actual wastewater lifting plant is finally placed and mounted on this base been. Ultimately, the necessary pipe and cable penetrations had to be provided.

The procedure described above makes it clear that that for the creation of a complete pumping station with a sewage lifting system a not insignificant one Time is required, which leads to the described cost disadvantage.

This is where the invention comes in, which is based on the object of avoiding the disadvantages described and a To create a pumping station that can be set up quickly and inexpensively.

To solve this problem, the invention provides that at least the shaft and the base plate to form a unit are summarized as a complete shaft structure. In an expedient embodiment of the invention the sewage lifting system is already installed on the base plate, which together with the shaft structure forms a complete unit.

As a result of the measure according to the invention, a complete, so to speak Pre-assembled pumping station to be used with the sewage lifting unit in a complete watertight Manhole structure is installed in one piece, can be a surprisingly short assembly time in practice reach the complete pumping station. It was found that the complete installation of the novel pumping station can easily be done within a single working day until it is ready for operation, and including digging the necessary excavation pit. When the latter is finished, all you need is the pre-assembled pumping station to be lowered into the excavation with a crane. Then the construction pit is backfilled, and the pumping station is practically complete.

The quick assembly time made possible by the invention offers considerable advantages. This eliminates the usual

borrowed long dewatering. This allows expensive pump and save energy costs. Another advantage is that there is no need for complex construction site equipment can be.

Further expedient refinements of the invention are given in the sub-claims.

The invention is explained in more detail below using the exemplary embodiment shown in the drawing. Show it:

FIG. 1 is a perspective view of a pumping station, and FIG

Figure 2 shows the cross-sectional view of a pumping station.

The pumping station 1 shown in the drawing, which already is preassembled and consists of one piece, comprises a shaft 2 and a base plate 4 or a shaft bottom 20. The latter is preferably made of concrete. The shaft 2 is circular in the embodiment shown designed like a pipe and consists of asbestos cement.

The illustration in Figure 2 shows the pumping station 1, such as it is in the ground 3. The pumping station has already been sunk into the excavation, and this is

has already been backfilled.

A sewage lifting system 8 is mounted on the shaft bottom 20 or on the base plate 4. For the proper Operation of the sewage lifting plant 8, an inlet line 10 and a pressure pipe 12 are provided, the shaft 2 being provided with corresponding connections for these lines. In addition, the shaft has 2 still has a row of crampons 14 on its inner wall, so that an operator can get into the shaft 2 and can carry out maintenance or assembly work.

The shaft 2 is closed at its upper end by a cover plate 16, which is expediently is provided with an entry hatch 18, specifically in the area of the row of crampons 14.

The pump station 1 shown also has a boiler vent 22 for the sewage lifting plant 8, as well as a room ventilation 26 and a room ventilation 28. The two the latter each have vapor hats 30 at their outwardly facing ends for ventilating the interior of the shaft 2. An external cabinet 24 is also attached to the ground 3 as a switch cabinet. The one in it The electrical circuit that is housed and required for operation can also be located in a remote location Buildings (not shown) are housed.

It can happen that when assembling the fcompetten Pumping station 1 in the excavated construction pit the problem of buoyancy due to water at extreme

C t

Groundwater situation. The base plate 4 is therefore made particularly strong ¹ "to achieve this, a buoyancy control in the aforementioned extreme groundwater situation. As FIG. 2 illustrates, the base plate 4 has a shoulder 6 in the form of an enlargement of the diameter, and the shaft 2 rests on this shoulder 6.

The assembly of the new pumping station is extremely easy. After digging a construction pit, the pumping station becomes 1 sunk into the excavation, and the cover plate 16 is then placed. Then the connection of the Shaft 2 to the inlet line 10 and pressure pipeline 12. Finally, the hoods 3O for Ventilation put on. The cover plate 16 is advantageously made of reinforced concrete, so that the Cover plate 16 can be driven over, for example, up to 40 tons is.

The particular advantage of the new pumping station 1 is that it is delivered to the construction site fully assembled and unloaded by means of a crane not shown in the drawing and sunk into the excavation can be. Overall, a watertight, clean structure is created by the invention, which quickly and can be easily installed on the construction site. The diameter of the tubular shaft 2 can, for example between 1.2 m to 2.5 m, and the depth of the shaft can be, for example, up to 10 m.
