The innovation relates to a bottom-side closure for inspection shafts to be inserted into a sewerage system composed of sewer pipes, consisting of a base in the form of a cup with side wall extending in line with the manhole rings to be placed on it, in the bottom of which a channel is fortified, the axis of which goes through the center of the The base and the side wall of which has ^{diametrically opposed openings in the Ii 1} Iu ent of the channel to accommodate the sewer pipes *

From the creation of the Sehacht base on site, that is in the pit receiving the shaft, by bricking up or concreting, in recent years one has switched to prefabricate the base and insert the prefabricated base into the insert the pit receiving the shaft.

The well-known, prefabricated wooden plinths are so heavy, that the transport and especially the insertion into the pit receiving the shaft is associated with difficulties and are accordingly expensive. In many cases, therefore, the shaft base is still in the conventional manner in the The pit that accommodates the manhole is created “The heavy weight of the well-known, prefabricated manhole base is a major factor the thick floor in comparison to the plinth wall in »When measuring the thickness of the floor, it has been assumed so far that the floor must also be sufficiently thick in the area of the channel formed in the floor »

The innovation is based on the need for a lighter, easier-to-use base »

This is taken into account according to the innovation in such a way that in a manhole base of the type described in the in the essentially a base having a thickness corresponding to the thickness of the shaft wall in the region of the base formed in the base Channel is set off to the outside with the formation of a Yorprunges, such that the bottom over the entire Sehacht cross section an essentially constant thickness

knows «

In the case of manhole bases with one that rises outwards from the channel In a further embodiment of the furnace, the base has a base on the outside starting from the projection the inclination of the inside corresponding to the inclination in the same direction on.

The shaft base formed in this way is essential lighter than the previously known, prefabricated Schachtsoekel, and it can therefore be handled better, in particular it can be more easily inserted into the pit receiving the shaft deploy. The projection on the outside of the base also helps to fix the position of the base in the Pit receiving the shaft.

In the drawing is an embodiment of the innovation according to the invention Plinth shown «It show;

Figure 1: a vertical section through the base

Line A - A in Figure 3?

Figure 2: a vertical section through the base along line B - B in Figure 3?

Figure 3 '''shows a horizontal section through the base along line C - 0 in Figure 2,

The base 11 consists of the base 12 and the side wall 13. In the base 12, the channel 14- is formed , which in the side wall 13 into the openings 16, 16 ^! transforms"

The bottom 12, which has essentially the same thickness over the shaft cross-section, is in the region of the channel H after Deposed on the outside with the formation of a protrusion 121.

Inside (111) the floor 12 rises from the gutter 11 to the side landing 13 with the formation of the so-called berm. Starting from the projection 121, the base 12 faces on the outside an inclination in the same direction corresponding to the inclination of the inside on ο

After the pit has been excavated, the base 11 _{s is} expediently placed on the shaft base 17 after a gravel bed 18 has been introduced rests »

Claims (2)

Applicant; Johannes Bock, Dortmund-Kirchhörde, Patroklusweg 18 Claims 1) Bottom-side closure for inspection shafts to be inserted into a sewerage system composed of sewer pipes, consisting of a base in the form of a cup with side wall extending in line with the manhole rings to be placed on it, in the bottom of which a channel is forged, the axis of which through the center point of the base and the side wall of which in the plunge of the channel has diametrically opposed openings for receiving the sewer _{pipes 5,} characterized in that the base (12), which essentially has a thickness corresponding to the thickness of the shaft wall (13), is in the area of the base molded channel (14) is offset to the outside with the formation of a projection (121) in such a way that the bottom (12) has an essentially constant thickness over the entire shaft cross-section » ~ 2 - 2) Base according to claim 1 with a floor that is in a known manner from the channel to the outside touching, characterized in that the bottom (12) has an incline on the outside starting from the projection (121) the inside has corresponding, same-directional inclination.
