Description

Construction kit for a water pipe

Technical field of the invention

The invention relates to a building kit for a water conduit and a solid-walled tubular component for said building kit and a method of manufacturing the tubular component.

Technical background

In the field of rainwater harvesting, i.e. rainwater harvesting, rainwater conveyance and rainwater transfer, or in the field of forestry and of agriculture, such as crossing dirt roads, plastic pipes are mainly used in addition to traditional concrete pipes. Due to the cost and their weight advantage, composite pipes are preferably used. Corrugated and finned pipes are only of secondary importance. At the outlet of such a water supply pipe, an outlet opening is provided, adapted to the respective slope angle of the environment. The simplest and most economical solution is to cut the composite pipe obliquely, which, however, has the disadvantage that the hollow chambers formed by the corrugation are open. In practice, this economical solution is often rejected for visual reasons. Another solution is to manufacture outlet sections made of solid-walled pipes. This is complex and above all very expensive.

The object of the invention is to create a construction kit for a generic type water supply pipe, which can be manufactured in a simple and inexpensive way.

This objective is achieved by means of a construction kit of the generic type for a water supply pipe, having at least one plastic composite pipe with a central longitudinal axis and an outlet section comprising a outlet, characterized in that the outlet section is designed as a one-piece solid-walled tubular component separate from the composite pipe having a central longitudinal axis and first and second ends, in that the solid-walled tubular component has a tubular section, and at the first end a pipe sleeve adapted to the composite pipe, in that the tubular section is provided, on its outer wall, with external longitudinal ribs extending to the second end and parallel to the central longitudinal axis, to which are associated longitudinal channels formed on the inner wall of the tubular section, in that annular reinforcing ribs extending t on the circumference of the tubular section are formed thereon and in that annular channels formed on the inner wall of the tubular section are associated with the annular circumferential reinforcing ribs.

The solid-walled tubular component for the exit section can be produced very simply and inexpensively as a blank using a centrifugal casting process. When in use, only the outlet opening is cut obliquely. During the simple manufacturing process, longitudinal ribs on the outside and longitudinal channels on the inside are formed at the same time. The longitudinal channels, in particular the longitudinal channel located on the ground after installation, are used to allow the evacuation of a small quantity of water. The longitudinal ribs serve to stabilize the surrounding ground. In the selected centrifugal casting process, the longitudinal channels are formed almost by themselves when forming the longitudinal ribs.

The reinforcing ribs serve to stiffen the pipe section and at the same time establish a fit with the surrounding ground. The inner annular channels cause some flow throttling in the event of heavy rainfall.

There are other advantageous embodiments of the construction kit according to which:

- the following applies to the length L of the tubular section with respect to the internal diameter d of the composite pipe: 1.5 <= L/d <= 1.8;

- the outlet opening towards the second end of the tubular section is cut at an opening angle a obliquely with respect to the central longitudinal axis;

- the following applies to the opening angle a:
40°<= a <= 60° and in particular 45° <= a <= 57°;

- the following applies to the width B of the longitudinal channels with respect to the width b of the annular channels: B > b;

- the following applies to the width B of the longitudinal channels with respect to the inner diameter d of the composite pipe:
0.05 <= B/d <= 0.10;

- a transition section free of longitudinal ribs and longitudinal channels is provided between the pipe sleeve and the area of the pipe component provided with longitudinal ribs.

A variant relates to a solid-walled tubular component for a construction kit according to the invention. Another variant relates to a particularly advantageous method of manufacturing the solid-walled tubular component using a centrifugal casting method.
