Abstract

A pipe construction kit for a sewer pipeline comprises several pipes made of plastic, which exhibit a circular cross-section. Between in each case two pipes there is to be arranged a shaft base body made of plastic, exhibiting a central connection section. The connection section exhibits a foot having a supporting surface and, diametrically thereto, a connection element for a shaft. On both sides of the connection section there are formed pipe sections for connection with the pipes. The diameter d of the shaft is significantly smaller than the diameter D of the shaft base body.

Claims

1. Pipe construction kit for a sewer pipeline (1), comprising

several pipes (2), made of plastic, having a circular cross-section,

in each case, a shaft base body (5) having a diameter D and to be arranged between two pipes (2) and to be connected with said pipes (2) by means of sockets (6),

in each case, an inspection and flushing shaft (9), which has a circular cross-section and a diameter d, to be connected with the shaft base body (5),

wherein the shaft base body (5) is provided with a central connection section (12) and, on both sides on said connection section (12), pipe sections (13) with a circular cross-section for connection with said pipes (2),

wherein the connection section (12) exhibits a supporting surface (17) and, diametrically opposite said supporting surface (17), a connection element (18) for said inspection and flushing shaft (9),

wherein the diameter D of the shaft base body (5) is larger than the diameter d of the inspection and flushing shaft (9),

and

wherein the shaft base body (5) is designed as a composite pipe with a corrugated outer pipe section (14, 14′

) and an essentially cylindrical inner pipe section (15).

3. Pipe construction kit according to claim 1, wherein for the diameter d of the inspection and flushing shaft (9) the following applies with respect to the diameter D of the shaft base body (5):

0.1 D≦

d≦

0.8 D.

4. Pipe construction kit according to claim 1, wherein the supporting surface (17) is formed on a foot (16) of the connection section (12).

5. Pipe construction kit according to claim 1, wherein the connection section (12) exhibits approximately a horseshoe cross-section.

6. Pipe construction kit according to claim 1, wherein laterally between the supporting surface (17) and the connection element (18) for the inspection and flushing shaft (9) there is formed at least one connection element (21, 22) for a sewage connection pipe (25).

7. Pipe construction kit according to claim 5, wherein for the diameter b of the at least one connection element (21, 22) for a sewage connection pipe (25) the following applies with respect to the diameter D of the shaft base body (5):

0.05 D≦

b≦

0.4 D.

8. Pipe construction kit according to claim 1, wherein the connection element for the inspection and flushing shaft (9) is designed as a shaft connection surface (18).

9. Pipe construction kit according to claim 5, wherein the at least one connection element for the sewage connection pipe (25) is designed as a feed connection surface (21, 22).

11. Pipe construction kit according to claim 1, wherein the inspection and flushing shaft (9) is designed as a composite pipe with external corrugations.

13. Pipe construction kit according to claim 1, wherein a removable cap (10) is provided for closing the inspection and flushing shaft (9).

14. Pipe construction kit according to claim 1, wherein the shaft base body (5) is designed inline.
