Abstract

The invention discloses a precision adjustment device of track-and-field runway steel pipe projection edge in the sports facility technique domain, which comprises the following parts: track-and-field runway (1),several water expansion adjusters (2) on the steel pipe projection edge line segment of (1) outer runway, several length adjusters (3) on the steel pipe projection edge arc segment of (1) inner runway, several hollow pipe adjusters (4) on the steel pipe projection edge line segment of (1) inner runway, several support adjusters (5) under the (1) steel pipe projection edge line segment.

Description

Technical field: [0001] The invention relates to a device for adjusting the precision of a steel pipe protruding edge of a runway in a track and field field, belonging to the technical field of sports facilities. technical background: [0002] In 1998, my country announced the implementation of new technical standards for track and field tracks formulated by the IAAF. Taking the 400-meter standard runway as an example, the actual running line (calculation line) is required to be 400 meters, and the allowable deviation value is +0.04 meters; the building line (measurement line) is 398.12 meters, and the allowable deviation value is +0.04 meters. [0003] In order to reach the above-mentioned technical standards, domestic track and field runways adopt metal, cement, brick, wood, stone or rubber ledges respectively. The inventor has invented the "track and field field steel pipe edge" that the patent No. is 89103082.4 in 89 years. Although this patented technology can solve c...
