Description

The following work was carried out to construct the system:

  • Construction site setup, provision of BE, construction site clearance
  • Manufacture of a pilot probe / Conduct a thermal response test including evaluation
  • Design of the system using analytical calculations and carrying out a hydraulic calculation
  • Preparation of approval, execution, work and assembly as well as revision planning
  • Construction of a total of 24 geothermal probes of 70 m each including disposal of 121 t of drilling cuttings and disposal of excess drilling fluid.
  • Construction of 448 m³ of trenches for the laying of pipelines / excavation for the construction of an excavation pit for the distribution shaft
  • Disposal of 549 t of surplus soil
  • Supply and installation of 46 t of rolled gravel, 114 t of cable sand and 294 t of backfill material as well as reinstallation of 440 m³ of laterally stored excavated material
  • Laying of 1,302 m of connecting pipes and connecting the connecting pipes to the geothermal probes. Laying of 8 m of collecting pipe.
  • Installation of a 24-way distribution shaft and connection of the connecting and collecting lines to the shaft
  • Filling the system with 5 m³ of heat transfer medium and carrying out the hydraulic balancing
  • Final functional test of the system
