Industry, by analyzing boring extracting soil soil sample, formulates bored grouting depth, at the same time carries out cement mortar preparation ratio of mud control and exists
0.4:1～0.6:1, drilling construction is once completed, and grouting pipe is inserted immediately carries out slip casing by pressure, in this operation, slip casting pressure
Power is controlled in 0.2Mpa～0.4Mpa, and hell need to be blocked tightly, when slurries leak, stops slip casting, moves to next hole position
Operation, after 2 test hole position slip castings are completed, Suspend Job after cement mortar initial set, is chosen two hole position centre positions and is bored
Sampling is visited, Inspection and analysis slip casting osmotic effect determines therefrom that follow-up slip casting cloth pitch of holes and grouting pressure；
(4-4), bored grouting construction implements bored grouting construction using railways train operation interval time, according to first outside and then inside order
Carry out, i.e., first complete peripheral bored grouting, after slip casting final set forms seepage proof curtain, then drilling on inner side slip casting is carried out, until complete
Into the construction of whole bored groutings；
(5), reinforce section of railway track to recover under construction normal temperature 10 days after mortar depositing construction is completed, slip casting roadbed complex intensity can reach
To more than 85%, using the artificial railway roadbed mud tiny fragments of stone, coal, etc. of hole-specifically removing to road bed absolute altitude, 0.15m thickness yellow sand filter protections are backfilled successively
Layer, 0.2m thickness rubble ballast layers, make firm by ramming, implementing track maintenance operations, after reaching basic train-passing through conditions, railway reinforced device are removed successively, mend
Railway ballast is filled, Comprehensive trimming is carried out, recovers railway original technology standard.
