Description
Technical field
The utility model is related to civil construction technical fields, and in particular to a kind of civil engineering side slope protection grouted anchor bar.
Background technology
Project post-evaluation has slope protection and retaining structure to protect two classes.The common measure of slope protection has mortar or tabia
Deng plastering, whitewashing, pneumatically placed concrete, mortar flag stone revetment, shotcrete bank protection, anchor and spray net bank protection etc..Such measures are mainly protecting
The rock weathering of excavation slope slope surface peels off, broken falls and phenomena such as a small amount of falling rocks chip off-falling.The side slope protected should have enough
Stability, for unstable side slope, then first supporting and retaining system is protected again.The type of retaining structure is more, such as retaining wall, anchored bolt retaining wall, resists
Sliding pile etc..The existing protective action of these retaining structures, and play the role of reinforcing slopes.Using engineering measure bank protection, often excessively
Intensity effect is pursued, destroys ecological natural, landscape effect is poor, and over time, concrete surface, mortar flag stone face
Meeting weathering, aging, or even damage, later stage regulation is costly.
Grouted anchor bar is to be actually needed and developed according to China's Tunnel Engineering, Reinforcement Works of Rock Slopes, coal mine roadway engineering etc.
New product.The anchor bar body of grouted anchor bar uses hollow design, body of rod mesoporous to be used as drilling high-pressure blast aquaporin and slip casting channel,
Compared with the solid body of rod, hollow lever design can get better rigidity and shearing strength.Anchor pole external surface overall length standard is big
Pitch screw structure, cutting and spreading of the helicitic texture convenient for anchor pole, increases anchor bar body and slip casting material compared with the smooth body of rod
The bond area of material is to improve anchor force.
Currently, in the construction process, it is often necessary to carry out side slope protection, but in protection process, it may appear that the soil body caves in
The case where, wet region is more especially being glued for soil property, such as situations such as lakeside, existing grouted anchor bar when in use, by anchor
Bar is squeezed into the soil body, then inwardly carries out slip casting, however the structure of grouted anchor bar is all single hollow tube tubulose, grout outlet side
To single, the matrix formed in the soil body after slurries injection solidification is also more local, and the slurry stream of injected hole goes out without successively
Sequentially, more complicated grouted anchor bar can start slip casting in side wall, in slurries injection process, flowed out from side wall, form reflux, overflow
Go out the soil body, and during anchor pole is squeezed into, the soil body of sidewall locations is extruded consolidation, and most slurries are difficult outflow so that
The combination of medium position and the soil body is poor, anchor pole occurs and fixes shakiness, protection effect is poor.
