speed•pipe® bundle ground gabo Systemtechnik SRV-G und SRV-G tc Laying instructions 43 The following topics under point 17 apply for SRV-G tc and for the application of a speed•pipe® ground as a single micro duct. The structurally engineered specifications and standards for the following laying procedures have to be fulfilled and clarified with the according administrations. Important The speed•pipe® bundle ground SRV-G tc must not be wound off by rolling the drum over the ground. By doing so there is the risk to squeeze the speed•pipe® ground. Therefore, a trailer for drums or a laying carriage always must be used. INSTALLATION RECOMMENDATION*: open trench laying direction pulling direction SRV-G tc surface trench bottom SRV-G tc SRV-G tc spool The SRV-G tc must be wound off the coil as described in the illustration (see picture). It is particularly important to respect the linear laying under tension (spool slowed down in a controlled manner). It is not permitted to unwind the SRV-G tc on the flange (in direction of the coil axis, because of spiral forming of the SRV-G tc). Avoid a wave like laying (neither horizontal nor vertical) coercively. * Special conditions on the construction site or laying process may differ from the recommended principle. 17. Types of installation of the SRV-G tc in direct buried installation. 17.1 In the open trench. Important note
