The invention further relates to such a draining pipe mesh (1) which is provided with intersection boxes (5). The intersection box (5) is provided with access tubes (8) adapted to extend to the surface of the shotcrete. In a particularly advantageous embodiment of the invention, the access tubes (8) may be provided with flushing units (14) or pressure indicators (15). |
