Double-track-distance railway concrete sleeper
The invention relates to the technical field of railways, in particular to a double-track-distance railway concrete sleeper. An embedded iron seat component is fixed on the upper surface of a special-shaped sleeper, a rail is fixedly mounted on the upper surface of the middle of the embedded iron seat component, the embedded iron seat component is of a double-limb structure, and a wedge-shaped plate is arranged in adjacent cavities of double limbs. The wedge-shaped plate in the sleeper is made of a polymer composite material, insulation resistance between the left steel rail and the right steel rail of the same adjacent rail can be improved, and the reliability of a rail circuit is improved; and the wedge-shaped plate has certain elasticity, so that the impact force of a wheel rail is reduced.
本发明涉及铁路技术领域，具体涉及一种双轨距铁路混凝土轨枕，异形的轨枕上表面固定预埋铁座构件，预埋铁座构件中部上表面固定安装铁轨，其中，预埋铁座构件为双肢结构，双肢相邻空腔内设置楔形板；本发明轨枕中的楔形板采用高分子复合材料，有利于提高相邻同一轨道左右两根钢轨之间的绝缘电阻，提高轨道电路的可靠性；楔形板具有一定弹性，有利于降低轮轨冲击力。
