Step 2: carry out bolt anchoring with the anchoring adhesive of high strength in the anchor hole bored on bed plate (8), and with high-strength bolt (3), H type is indulged girder steel (1) and be fixed on bed plate (8); By welding, H type tail trimmer (2) being fixed on longitudinal H type again indulges on girder steel (1), and H type tail trimmer (2) stretches out certain length in every side, bed plate (8) left and right sides;
, under ensureing each H type tail trimmer (2), there is concrete pier in step 3: lay vertical concrete pier (6) under H type tail trimmer (2);
Step 4: lay a vertical jack (4) below each H type tail trimmer (2) extension, vertical jack (4) top is connected with H type tail trimmer (2) by tetrafluoro plate (5), and bottom is directly placed in above vertical concrete pier (6);
Step 5: track plates (7) Integral synchronous jacking: simultaneously control all vertical jack (4) by control system, by track plates (7) jacking to corresponding height;
Step 6: the horizontal jack (10) controlled by control system makes track plates (7) move to assigned position;
Step 7: after track plates (7) translation puts in place, between bed plate (8) and rubble rolling layers, adopt CGM cement-based polymers mortar to be in the milk, it is made to return to design elevation, slip-casting lifting process will carry out Real-Time Monitoring, adopt vertical displacement sensor and horizontal displacement sensors to carry out Simultaneous Monitoring to the height of bed plate (8) and horizontal movement change simultaneously, ensure track rising height and control of horizontal displacement precision.
7. the method as described in claim 5 or 6, it is characterized in that, between step 3 and 4, also comprise bed plate (8) off-load step, be specially the inserts of confining bed that the line of cut (12) along each 5cm in bed plate (8) both sides cuts and convex gear platform (13).
8. method as claimed in claim 4, is characterized in that, after step 6, also perform following steps,
Step 7: check lifting value, checks that main frame lifting data and sensing data check rising height;
Step 8: regain jack;
Step 9: fastener recovers, and lift plate section and lift plate two ends track along sledge, adjustment, high measurement led by contact net, lifts plate track on the same day and adopts V≤120km/h deviation management standard along sledge and accurate adjustment;
Step 10: after Cementer completes, lifting frock is removed, adopt shrinkage joint packing material (such as, silicone material) recover former shrinkage joint, and backfill the boring of bed plate (8) with shutoff mortar (such as, polymer quick-setting mortar) and remove the boring after frock;
Step 11: construction quality and orbit adjusting return inspection: scene is checked the bed plate (8) having noted slurry, sees if there is the position that non-slip casting is full, and inspection is carried out back to Rail inspection.
9. method as claimed in claim 7, wherein, finds that lifting value is less than when fixing one's aim in advance, repeats step 5,6 steps in step 7.
10. method as claimed in claim 5, is characterized in that, after step 7, also perform following steps,
Step 8: check that main frame lifting data and sensing data check rising height and horizontal movement;
Step 9: regain jack cylinder;
Step 10: fastener recovers, and lift plate section and lift plate two ends track along sledge, adjustment, high measurement led by contact net, lifts plate track on the same day and adopts V≤120km/h deviation management standard along sledge and accurate adjustment;
Step 11: remove lifting frock after Cementer completes, adopts shrinkage joint packing material to recover former shrinkage joint, and with the boring after the boring of shutoff mortar backfill bed plate (8) and dismounting frock;
Step 12: construction quality and orbit adjusting return inspection: scene is checked the bed plate (8) having noted slurry, sees if there is the position that non-slip casting is full, and inspection is carried out back to Rail inspection.
11. methods as claimed in claim 10, wherein, find that lifting value, displacement value are less than when fixing one's aim in advance, repeat step 5,6,7 in step 8.
