Heavy load prestressed reinforced concrete sleeper and mine underground rail travel track structure

The utility model belongs to the technical field of mine transportation the technical of the orbit and specifically relates to a heavy load prestressed reinforced concrete sleeper and mine undergroundrail travel track structure is related to, including the sleeper body, the gauge of sleeper body is first default, the rail length of sleeper body and the ratio between the first default are 460287,the wide range of value that compares with the rail is high of rail of sleeper body is 4029 to 75. In this scheme, the sleeper contraction in length can reduce roadway section 9% and control after being 2300mm, can effectively reduce tunnel excavation project volume, reduces the track structure width, dwindles roadway section, reduces the engineering volume, reduces the tunnel investment. 本实用新型涉及矿山运输轨道技术领域，尤其是涉及种重载预应力钢筋混凝土轨枕及矿山地下有轨运输轨道结构，包括轨枕本体；所述轨枕本体的轨距为第预设值，所述轨枕本体的轨长与第预设值之间的比值为460/287，所述轨枕本体的轨宽与轨高的比值范围为40/29至7/5。本方案中，轨枕长度缩短为2300mm后，可减小巷道断面9％左右，能够有效减小巷道开挖工程量，减少轨道结构宽度，缩小巷道断面，降低工程量，减小巷道投资。
