Description
Technical field
The present invention relates to high-speed railway subgrade conserving material technical field, add in particular to a kind of repairing of high-speed railway subgrade
Gu Special grouting material and its grouting method.
Background technology
The high-speed railway speed of service is fast, and dynamic loading is big, in order to ensure the stability and security of bullet train operation, to height
Fast railway bed situation proposes strict requirements.Due to the complexity and diversity of geological conditions, foundation of road bed is transported by train
Repeated stock and vibration effect during row, uncontrollable sedimentation can be produced in some special areas, and occur coming to nothing, bursting and become muddy when a thaw sets in emits
The diseases such as mud, adverse effect is all generated to train operation efficiency, driving comfort and operation safety etc..Therefore, it is necessary in time
To these disease problems, it is effectively renovated.
The research of current cement based grouting material has had a lot, and performance is diversified, and has and be much successfully applied to state
The various aspects of people's construction field, also there is substantial amounts of related invention Patent Publication.
Entitled such as Patent No. " CN103880372B " " is used for cement based grouting material, its preparation side of reinforcing and repairing
In the Chinese invention patent of method and its application ", the 2h compression strength of its injecting paste material reaches 5MPa, and compression strength is not less than within 1 day
30MPa, it is adaptable to the pit shaft slip casting in mine, colliery etc..
The Disease Treatment field on high ferro roadbed, also has many scholars to propose the repair materials of corresponding engineering method, such as specially
Profit number is the Chinese invention patent of entitled " soft clay area high-speed railway subgrade settles regulation method " of " CN105064157A ", with
And promulgated by the State Council in entitled " the existing high-speed railway subgrade deformation Disease Treatment structure of micro-disturbance " of Patent No. " CN202830649U "
Bright patent, the two patents carry out rotary churning pile reinforcing and grouting and reinforcing using cement single slurry, cement-sodium silicate double liquid,
The soil body to high ferro roadbed carries out lifting reinforcing, but the requirement of its slip casting slurry set strength is low, and core strength is left in 2-3MPa
The right side, is not suitable for the space filling high of intensity requirement between high ferro roadbed supporting plate and graded broken stone layer and reinforces.
In sum, the research of current cement based grouting material has a lot, using also very extensive, such as pit shaft slip casting, public affairs
Road roadbed reparation etc..And repair field in high-speed railway subgrade, it is contemplated that and the particularity of high-speed railway, for the note of high-speed railway
Pulp material not only to meet within certain activity duration construct mobility and holding capacity it is good, process of press in continuously not plugging, also
Needs are simple to operate, meet hour intensity super hardening demand high, and later strength higher, good body are also required in performance
Product stability, adhesion strength and endurance quality.The current injecting paste material reinforced specifically designed for high-speed railway subgrade repairing and slip casting
Reinforcement means rarely has research to apply.
The content of the invention
