Splitmaster
2.1 Technical problems of the invention = technical task and objective The traditional method involves laying pipes in the gravel and adjusting them until they are at the correct height relative to the top edge of the lawn, perfectly straight, or at the desired slope. This is not easy for amateurs and requires considerable skill. 2.2 Solution of the problem or technical task. To make the correct alignment of the pipes absolutely easy, even for laypersons, so that everyone can do it, so-called skewers (Splitmaster, Fig. 3) are clipped onto the pipes to solve the problem. The spikes are then pressed into the ground and aligned with a spirit level until they are perfectly straight or at a slope and at the correct height to the top edge of the lawn. The spikes clipped onto the pipe, which are firmly anchored in the ground, prevent the pipe from slipping. The second pipe is then aligned parallel to the first pipe at a certain distance using a spirit level. Now the split can be leveled off using a straightedge or a board. 2.3 Application example. Application examples include the construction of a terrace, a path, or a square. The invention makes it possible for anyone to pave a terrace, path or square exactly level or with a slope on one or two sides.
