Many people want to know what are the anchoring regulations for spiral spikes? The following coach screw spike manufacturers will take you to know more about it.
(1) Spiral spikes are anchored with sulfur cement mortar. The coach screw spike manufacturer tells you that the formula and preparation process of sulfur cement mortar should meet the relevant regulations of railway track construction and acceptance specifications.
(2) Before the wrong fixation, the debris in the reserved holes of the sleeper and the adhesions on the spiral spikes should be removed. The coach screw spike manufacturer tells you that the screw spike should be dry and its temperature should be kept above 0℃.
(3) The anchoring method should adopt anti-anchor, and the spiral spike should be positioned with a mold. The coach screw spike manufacturer tells you that the anchoring grout is injected into the hole from the pillow bottom, and after solidification, it is straightened and demolded. When anchoring, the bottom of the reserved hole should be blocked tightly to prevent slurry leakage. After the anchoring slurry is injected into the hole from the pillow surface, the spiral spike should be rotated slowly from left to right and inserted into the position vertically. When the sulfur cement mortar is injected into the hole, the temperature should not be lower than 130°C, and segregation should be prevented, and one hole should be filled at a time. The coach screw spike manufacturer tells you that the grouting depth should be 20mm longer than the length of the screw spike inserted into the hole. The top surface of the anchoring grout should be level with the rail groove surface, and the overflowing residue should be removed and leveled after solidification.
(4) Spiral spikes should be perpendicular to the surface of the supporting rail groove, and the skew should not be greater than 2°. The coach screw spike manufacturer tells you that the point of intersection between the center line of the spike and the surface of the supporting rail groove should not deviate more than 2mm from the center of the reserved hole. Not less than 60kn.
The above is the coach screw spike manufacturer telling you what the relevant content of the screw spike anchoring regulations are, I hope it can help you.
