Boundary i.e. surface boundary, for use as sleeper for horse riding places, has angle elements including L-cross section shape with short and long sides, where part of angle elements and two-part segment lie on ground

摘要

The boundary (1) has angle elements (2) including an L-cross section shape with short and long sides (5, 6). A part of the angle elements and a two-part segment lie on a ground (40), and is arranged below a ballast structure. A height of the boundary is larger than or equal to 30 cm. The two-part segment is composed of an upper part and lower parts detachably connected with each other. The lower parts include an inverse T-shape cross-section, and are rigidly designed. The upper part is softly designed. The angle elements and the segment are custom-fit detachably connected with each other.
