地铁正线ZD(J)9道岔安装验收标准(国外英文资料) The acceptance criteria for the installation of the main subway line ZD (J) 9 All bifurcation adopts ZD (J) 9 dt170-4.0 K three-phase alternating current switch machine. The bifurcation shall be installed in accordance with the following requirements: A) the change of the track of the branch is no more than the limit, the basic rail is not moving, the sharp rail is moving in the same direction. B) the bifurcation should be square. The deviation of the two sharp rails of a single opening (or symmetrical bifurcation) must not be greater than 20 mm. C) the opening of the switch should be appropriate, and the pointed rail should be able to meet the basic rail. D) the sleeper should meet the requirements of the installation. If the switch does not meet the installation requirements, it shall be cleaned up by the department of the line and shall be installed after the installation standard of the switch device. The installation of the switch shall meet the following requirements: A) adopt the galvanized switch machine installation, tighten bolts to use the anti-loose bolts, and the rods are double pressed nuts. B) the Angle iron of fixed length Angle steel should be with the rail tightness (excluding the waist). C) the base Angle of the long base Angle is perpendicular to the straight line of the direct strand of the single opening, the deviation should not be greater than 20mm. The short base Angle of the fixed switch equipment should be perpendicular to the long base Angle. E) the adjustment rod, the means of the pole or the lock rod, the end pole, the first link bar and the long base Angle steel are parallel, the deviation of each other is not greater than 20 mm. The parallel deviation of the switch equipment and the direct line of the direct strand or the center line of the symmetrical bifurcation shall not be greater than 10mm. In the case of the fine adjustment of the rod, the distance between the position and the motion shall not be less
