track fasteners manufacturer is a kind of railway spike and one of many railway accessories, which plays a fastening role in the fixing of the entire railway track. The importance of track fasteners manufacturer is undeniable, so it is necessary to pay special attention to track fasteners manufacturer in daily inspection and maintenance.

On the one hand, it is necessary to ensure that the quality of the track fasteners manufacturer is qualified, and on the other hand, it is necessary to properly install and anchor the track fasteners manufacturer. So, what standards should be achieved when anchoring track fasteners manufacturer? The following will summarize and introduce this problem.

1, track fasteners manufacturer with sulfur cement mortar anchorage. The formulation and preparation process of sulfur cement mortar shall comply with the relevant provisions of the railway track construction and acceptance code.

2. Before anchoring, the debris in the sleeper reserve hole and the adhesive on the track fasteners manufacturer should be cleared. The track fasteners manufacturer should be dry and its temperature should be kept above 0 ° C.

3, the anchoring method should use anti-anchor, track fasteners manufacturer with mold positioning. The anchor slurry is injected into the hole from the pillow bottom, and the mold is reversed after solidification. When the anchor is positive, the bottom of the reserved hole should be plugged tightly to prevent slurry leakage. After the anchor slurry is injected into the hole from the pillow surface, the track fasteners manufacturer should rotate left and right and slowly insert it vertically. When the sulfur cement mortar is injected into the hole, the temperature should not be lower than 130℃, and segregation should be prevented. One hole should be filled at a time, and the grouting depth should be 20mm longer than the length of the track fasteners manufacturer inserted in the hole. The top surface of the anchor slurry should be flat with the surface of the rail groove.

4, the track fasteners manufacturer should be perpendicular to the rail groove surface, and the skew should not be greater than 2°. The intersection point between the center line of spike and the groove surface of the bearing rail shall not be greater than 2mm from the center of the reserved hole, the bottom of the spike round table shall be higher than the groove surface of the bearing rail, but shall not be greater than 2mm, and the pulling force of the track fasteners manufacturer shall not be less than 60kn.
