[0013] When the track foundation settlement height is above 100, the adjustment method is as follows:

[0014] 1) measuring the settlement of each part of the rail, preparing the concrete or cement required for the foundation, preparing the base plate, lengthening the casing and connecting the extension pipe in advance;

[0015] 2) loosening the casing bolt of the rail fixing system in the range of the settlement height of 100 mm and its surroundings, lifting the rail together with the fixing system, and lifting height is 200 mm;

[0016] 3) The lifting pad used for micro-precipitation of the rail is withdrawn, and can be reserved for secondary sedimentation; [0017] 4) The newly added pre-buried bottom plate, elongated sleeve and connecting extension tube are The pre-embedded board in the original system is connected with the pre-embedded bushing, and then the height of the embedded board is adjusted by connecting the extension tube;

[0018] 5) supporting the baffle, preparing to pour concrete or cement;

[0019] 6) first screw the casing bolt to the adjusted elongated sleeve on both sides, and then pour the concrete or cement after tightening;

[0020] 7) After the concrete or the cement is solidified, the template is removed, the rail is lowered, the rail is fine-tuned, and then the base is fixed by bushing bolts, and the adjustment is completed.

Advantageous effects of the invention

Beneficial effect [0021] The beneficial effects of the present invention are: After the foundation of the rail appears to be settled, the settled track is lifted together with the fixing system by the system for adjustment, and depending on the amount of settlement, the heightening pad or the height adjusting base can be adopted. The method is to adjust the height direction, which reduces the process of disassembling and fixing the system, saving labor and labor. The track foundation height adjustment system ensures the stability and reliability of the track during long-term use. The use of the track foundation height adjustment system can solve the problems of complicated construction of the existing track in the process of height adjustment and insufficient specification of the material to be adjusted, and save a lot of manpower and material resources for the customer.
