Abstract: The portable mechanically assembled ground fixation stake device is applied to the engineering of treating land earthwork, water-based desilting, excavating materials, moving, land, underwater heavy objects, civil engineering, harbor, river, lake construction and the like, and is characterized in that the whole device is fixed only by the action of the working tensile force itself. The whole device has six stake columns 2a, 2b, 4a,4b, 9, 1) arranged on the ground, wherein four constituent brackets (2a, 2b, 4a, 4b) are supported on the ground. The top ends of the four supports are mounted on the shaft (6), and a cuboid rigid block (15) is mounted in the middle of the shaft (6).

Abstract: A crosslinkable rubber composition comprising:—natural rubber or a rubber blend comprising natural rubber and 0-25 wt % EPDM,—elemental sulfur—one or more sulfur cure accelerators or sulfur donors, and—at least one organic peroxide with a 10 hour half-life in monochlorobenzene at a temperature in the range 95-145?C, wherein the weight ratio of the total amount of sulfur cure accelerators and sulfur donors relative to the amount of elemental sulfur is not higher than 2.5, and wherein the composition is substantially free of non-diene rubber.
