Definitions
- the telescopic column pipe When the top covering is in a lowered position the telescopic column pipe facilitates reconstruction of a street or road, particularly when the top covering is adjusted to a final position before the street, or road is surfaced. Moreover - and this is also important - the top covering can follow movements of the ground, if any, at settling or frost action of the ground due to the fact that the top covering is floating on the street or road surfacing. The top covering accordingly will remain at the ground level independently of ground movements, if any. Thus, with a telescopic column pipe of this construction it is not necessary normally to effect adjustments, and if this is nevertheless necessitated by street or road work, the adjustment can be made in a relatively simple manner.
- Figure 2 is a vertical sectional view of the upper portion of the telescopic column pipe.
- the column pipe shown in the drawings is located in the ground as will be seen from Figure 2 and comprises a lower pipe element 10 which can be made of plastic material and can be connected at the lower end thereof for example to a well of any type, which is not shown herein.
- the column pipe comprises also an upper pipe element 11 which also can be made of plastic material and is inserted into the lower pipe element 10, a resilient sealing ring 12 being provided between the pipe elements.
- This sealing ring allows displacement of the upper pipe element in the lower pipe element and also allows relative angling of the pipe elements.
- a hollow socket 13 is connected to the outside of the upper pipe element 11, and this socket too can be made of plastic material and forms a top covering rim 14 at the upper end thereof.
- the flange 17 or the flanges function as a screw thread which provides axial displacement of the pipe element 11 and elements connected therewith, when the top covering rim 14 is being rotated, by cooperation with the surrounding ground material.
- a flange or several flanges are arranged as proposed according to the invention it is not necessary that the top covering rim 14 projects from the socket 13 as shown in the drawings, to support the top covering on the ground surface.
- Sufficient ⁇ support is provided by the flange or flanges engaging the ground material, in order to make the top covering a floating covering following the movements of the ground.
