The geodetic systems: local and national

Why two systems at GANIL ?

1- Local system

GANIL has a "local" geodetic system : used to align and position the functional components.

2- National systemA general topographic plan of the site was produced in 2003: expressed in the French national geodetic systems.

The construction plans of the SPIRAL2 project were produced on the basis of the topographic plan.

Connection consisted :

to transfer 4 points (in blue) to the outside of the installations.

on the topographic plan, 4 stations (in red) known in the national system were selected .

A change of system :

transformation

This operation had 2 objectives:

"register" precisely both construction and building plans to match our local system,

simplify the installation of the process to guarantee the required connection.

Phase 2 radioactive beam transport line

This geodetic network had two objectives:

to provide reference points to allow installation of the process at level -9.50 m,

to monitor movements of the building at level 0.

Pillar will be anchored on at the geologically highly stable bed and isolated from the future infrastructures and their excavations.

These pillars will remain in position throughout the lifetime of the accelerator

How to install the process geographically ?

Network takes into account the land occupied by the worksite, earthworks area and final layout

Pillars must be installed after the earthworks and before starting the civil engineering work for the building

Surveying for surface network will be carried out by TDA tacheometer with GPS observations

Simulation remains to be done

Final accuracy expected : ± 3.0 mm ?

This solution was rejected because of the risk of neutron scattering at level 0 due to the difficulty to press down the calcareous stone around the shaft

performed before

the concrete slabs of the higher levels are poured (ceiling of

reference marks will be sealed in the slab at predefined positions,

their Cartesian coordinates will be determined using the geodetic pillars of the first order network.

SUMMARY

Slide22

Summary

Final goal : to guarantee the future connection of the new accelerator,

The connection requires designing a “surface” network linked to the local survey,

The local system was “connected” to the national system : to express in both systems the process and construction plans requirements,

The first order network geodetic pillars will be surveyed by tacheometer TDA 5005 coupled to a differential GPS,

The

surface network will be transferred to the floor accelerator tunnel, in order to define the reference network for aligning all functional components. See poster: « Survey and Alignment Concept for the SPIRAL2 Accelerator »
