gabo Systemtechnik speed•pipe® bundle ground Laying instructions SRV-G und SRV-G tc 50 SRV-G tc are in general suitable for all Micro- and Minitrenching techniques. But until now there is no relevant long-time experience regarding damage to the road surface and although the influence for SRV-G (tc) and the speed•pipe® ground. We recommend using these techniques on little loaded walkways and streets. Take care for following conditions: • The trench bottom have to be free from stones (layed ideally in sand bed). • Throw no stones on speed•pipe® ground or SRV-G tc. • Linear laying of the SRV-G tc. • Laying under tension. • No twisting of the SRV-G tc. • Realize bending radius so big as possible. • Branch off with controlled bending, e. g. with TBS or LBS. • Max. temperature for SRV-G tc and speed•pipe® ground is 80 °C. By sealing with heated pottant (e. g. hot asphalt) the bundle respectively the speed•pipe® ground have to be protected against temperature. This can be handled for example with a sufficient overlap of sand (≥ 2 cm). 17.4 Laying with Micro- and Minitrenching.
