Remediation capsule
A renovation capsule is a component with the help of which a gas or water house connection can be renewed trenchlessly in accordance with the standards.
General
For the renovation of house connections , including the service line, there are different products and methods. The spectrum ranges from the excavation and complete removal of the old stock with subsequent relocation to products that enable trenchless relocation of a house connection. Trenchless construction is often preferred because it is very economical compared to conventional construction.
The part of the name - capsule comes from the pipe capsule , a design of building entries on which the renovation capsule is based.
construction
Refurbishment capsules essentially consist of the same components as a building entry , but differ in their dimensions. Since they are partially pushed into the old pipe , they are smaller than normal house entries. For additional security, they have a pull-out protection in the form of a plate that is screwed to the wall in the building.
function
In the case of a renovation capsule, the entire route of the house connection line remains unaffected, which means that the garden and traffic areas remain undamaged. All that is required is a head hole on the main line.
In order to create a new standard-compliant house entry, the pipe cannot simply be inserted into the house. The wall penetration must be made with the renovation capsule in order to meet all requirements of a building entry such as tightness, strength and service life.
When renovating a house connection with a renovation capsule, the existing gas pipe is used as an empty pipe for the new installation. A new line (usually made of plastic) is pushed through the old line. The new pipe must be at least two dimensional jumps smaller than the old pipe so that it can be pushed in without any problems. The resulting smaller cross-section of the new line must be taken into account in the design, but usually does not pose a problem. In the past, house connection lines were often oversized. In addition, the buildings to be refurbished often have newer and more effective heating systems and the need for heat is reduced due to building modernization with new insulation and better windows, etc.
