Description
Technical field
The present invention provides a kind of reinforcing grouting materials.
Background technique
Tunnel and culvert structure are mostly using concrete or reinforced concrete structure at present, concrete tunnel during operation
Easily there is cracking, the dew diseases such as muscle and percolating water in road or culvert structure, influence the normal use of structure.
The management measure of the diseases such as tunnel vault cracking chip off-falling sets set serves as a contrast, structure changes, pastes W steel band etc. in having.Inside set
Tunnel clearance can be greatly decreased in set lining method, may invade tunnel clearance, and the construction time is long, need to carry out speed limit processing to train；
Structure, which changes method, needs dead line current, and the construction time is long, seriously affects the normal operation of route；W steel band pastes method construction work
Skill is complicated, and bearing capacity is limited, general to the consolidation effect of vault cracking chip off-falling disease.
The management measure of culvert disease has inner sleeve frame structure, replacement cover board, glued crack closing etc..Wherein, inner sleeve frame structure method
Culvert headroom can be greatly decreased, caused water or the traffic capacity to decline, and the construction time is long, need to block route could construct；
Replacement cover board method needs dead line current, and Window time requires height, seriously affects the normal operation of route；Glued crack closes method
Fracture is repaired, and crack progressing is delayed, to improving the existing bearing capacity of culvert without positive effect.
Field of traffic has started gradually to reinforce tunnel and culvert using prefabricated assembled corrugated board structures, it builds up
A kind of composite structure is formed by the pouring material and existing structure filled after plate afterwards, common stress not only improves structure
Mechanical characteristic, and existing structure is reinforced.The pouring material that scene uses need to have that self drainage is good, it is fast it is hard, it is early it is strong,
